    Full Text Available University students frequently send and receive cellular phone text messages during classroominstruction. Cognitive psychology research indicates that multi-tasking is frequently associatedwith performance cost. However, university students often have considerable experience withelectronic multi-tasking and may believe that they can devote necessary attention to a classroomlecture while sending and receiving text messages. In the current study, university students whoused text messaging were randomly assigned to one of two conditions: 1. a group that sent andreceived text messages during a lecture or, 2. a group that did not engage in text messagingduring the lecture. Participants who engaged in text messaging demonstrated significantlypoorer performance on a test covering lecture content compared with the group that did notsend and receive text messages. Participants exhibiting higher levels of text messaging skill hadsignificantly lower test scores than participants who were less proficient at text messaging. It ishypothesized that in terms of retention of lecture material, more frequent task shifting by thosewith greater text messaging proficiency contributed to poorer performance. Overall, the findingsdo not support the view, held by many university students, that this form of multitasking has littleeffect on the acquisition of lecture content. Results provide empirical support for teachers andprofessors who ban text messaging in the classroom.

    This study aims to determine whether communicating via short message service text message during surgery procedures leads to decreased intake of fentanyl for patients receiving regional anesthesia below the waist compared with a distraction condition and no intervention. Ninety-eight patients receiving regional anesthesia for minor surgeries were recruited from a hospital in Montreal, QC, between January and March 2012. Patients were randomly assigned to text message with a companion, text message with a stranger, play a distracting mobile phone game, or receive standard perioperative management. Participants who were asked to text message or play a game did so before receiving the anesthetic and continued until the end of the procedure. The odds of receiving supplemental analgesia during surgery for patients receiving standard perioperative management were 6.77 (P=0.009; N=13/25) times the odds for patients in the text a stranger condition (N=22/25 of patients), 4.39 times the odds for those in the text a companion condition (P=0.03; N=19/23), and 1.96 times the odds for those in the distraction condition (P=0.25; N=17/25). Text messaging during surgery provides analgesic-sparing benefits that surpass distraction techniques, suggesting that mobile phones provide new opportunities for social support to improve patient comfort and reduce analgesic requirements during minor surgeries and in other clinical settings.

    Hispanic adults in the United States are at particular risk for diabetes and inadequate blood pressure control. Physical activity improves these health problems; however Hispanic adults also have a low rate of recommended aerobic physical activity. To address improving physical inactivity, one area of rapidly growing technology that can be utilized is text messaging (short message service, SMS). A physical activity research team, Text4Walking, had previously developed an initial database of motivational physical activity text messages in English that could be used for physical activity text messaging interventions. However, the team needed to translate these existing English physical activity text messages into Spanish in order to have culturally meaningful and useful text messages for those adults within the Hispanic population who would prefer to receive text messages in Spanish. The aim of this study was to translate a database of English motivational physical activity messages into Spanish and review these text messages with a group of Spanish speaking adults to inform the use of these text messages in an intervention study. The consent form and study documents, including the existing English physical activity text messages, were translated from English into Spanish, and received translation certification as well as Institutional Review Board approval. The translated text messages were placed into PowerPoint, accompanied by a set of culturally appropriate photos depicting barriers to walking, as well as walking scenarios. At the focus group, eligibility criteria for this study included being an adult between 30 to 65 years old who spoke Spanish as their primary language. After a general group introduction, participants were placed into smaller groups of two or three. Each small group was asked to review a segment of the translated text messages for accuracy and meaningfulness. After the break out, the group was brought back together to review the text messages

    Many studies assess provider-patient communication through text messaging; however, minimal research has addressed communication among physicians. The purpose of this study was to evaluate the use of text messaging by pediatric hospitalists. A brief, anonymous, electronic survey was distributed through the American Academy of Pediatrics Section on Hospital Medicine Listserv in February 2012. Survey questions assessed work-related text messaging. Of the 106 pediatric hospitalist respondents, 97 met inclusion criteria. Most were female (73%) and had been in practice messages, some (12%) more than 10 times per shift. More than half (53%) received work-related text messages when not at work. When asked to identify all potential work recipients, most often sent work-related text messages to other pediatric hospitalists (64%), fellows or resident physicians (37%), and subspecialists/consulting physicians (28%). When asked their preferred mode for brief communication, respondents' preferences varied. Many (46%) respondents worried privacy laws can be violated by sending/receiving text messages, and some (30%) reported having received protected health information (PHI) through text messages. However, only 11% reported their institution offered encryption software for text messaging. Physicians were using text messaging as a means of brief, work-related communication. Concerns arose regarding transfer of PHI using unsecure systems and work-life balance. Future research should examine accuracy and effectiveness of text message communication in the hospital, as well as patient privacy issues.

    To expand recently-developed text messaging systems with new technology-based solutions so as to allow persons with multiple disabilities to write messages. Two case studies were conducted. In Study I, the new technology-based solution involved vocal scanning of the alphabet letters to allow letter selection/writing and was assessed with a woman with blindness and extensive motor disability. In Study II, the new technology-based solution involved a touch-screen superimposed on letter symbols arranged alphabetically and was assessed with a man with acquired brain injury, motor disability and lack of speech. Each study involved an ABAB design. Participants learned to write their messages, to send them out and to listen to incoming messages during intervention sessions of nearly 30 and 20 minutes, respectively. Text messaging systems can be developed that allow participants with multiple disabilities to write messages.

    The objective of this study was to identify biomechanical measures that can distinguish texting distraction in a laboratory-simulated driving environment. The goal would be to use this information to provide an intervention for risky driving behaviour. Sixteen subjects participated in this study. Three independent variables were tested: task (texting, visual targeting, weighted and non-weighted movements), task direction (front and side) and task distance (close and far). Dependent variables consisted of biomechanical moments, head displacement and the length of time to complete each task. Results revealed that the time to complete each task was higher for texting compared to other tasks. Peak moments during texting were only distinguishable from visual targeting. Peak head displacement and cumulative biomechanical exposure measures indicated that texting can be distinguished from other tasks. Therefore, it may be useful to take into account both temporal and biomechanical measures when considering warning systems to detect texting distraction.

    Along with the development of technology today, humans are very facilitated in accessing information and Communicate with various media, including through the Internet network . Messages are sent by media such as text are not necessarily guaranteed security. it is often found someone that wants to send a secret message to the recipient, but the messages can be known by irresponsible people. So the sender feels dissappointed because the secret message that should be known only to the recipient only becomes known by the irresponsible people . It is necessary to do security the message by using the RSA algorithm, Using fingerprint image to generate RSA key.This is a solution to enrich the security of a message,it is needed to process images firstly before generating RSA keys with feature extraction.

    Full Text Available This paper discusses the enhancements made on the current mobile phone messaging software, namely the predictive text entry. In addition, the application also has a facility to abbreviate any unabbreviated words that exist in the dictionary, so that the message length can be reduced. The application was tested in a computer-simulated mobile environment and the results of the tests are presented here. These additional features will potentially enable users to send messages at a reduced length and thus reduce the cost of sending messages. Moreover, users who are not adept in using the abbreviations can now do so with features made available on their mobile phones. It is believed that these additional features will also encourage more users to use the predictive software as well as further improve users’ messaging satisfaction.

    2017-08-01

    Background Text messaging services could increase access to psychotherapeutic content for individuals with depression by avoiding barriers to in-person psychotherapy such as cost, transportation, and therapist availability. Determining whether text messages reflecting different psychotherapeutic techniques exhibit differences in acceptability or effectiveness may help guide service development. Objectives We aimed to determine: (1) the feasibility of delivering a psychotherapy-based text messaging service to people with depression identified via the internet, (2) whether there is variation in satisfaction with messages according to the type of psychotherapeutic technique they represent, and (3) whether symptoms of depression vary according to receipt of each message type and participants' satisfaction with the messages they received. Methods For this study 190 US adults who screened positive for a major depressive episode (Patient Health Questionnaire (PHQ-9) score ≥10) were recruited from online advertisements. Participants received a daily psychotherapy-based text message 6 days per week for 12 weeks. Text messages were developed by a team of psychiatrists, psychologists, and social workers to reflect three psychotherapeutic approaches: acceptance and commitment therapy (ACT), behavioural activation, and cognitive restructuring. Each week the message type for the week was randomly assigned from one of the three types, allowing for repeats. Participants were asked daily to rate each message. On the 7th day of each week, participants completed a two-item depression screener (PHQ-2). Web-based surveys at baseline, 6, and 12 weeks were used as the primary measure of depressive symptoms (PHQ-9). Results Of the 190 participants enrolled, 85 (45%) completed the 6-week web survey and 67 (35%) completed the 12-week survey. The mean baseline PHQ-9 score was 19.4 (SD 4.2) and there was a statistically significant mean improvement in PHQ-9 scores of -2.9 (SD 6.0; p

    Full Text Available In the work are researched problems, which arise during hiding of messages in text environments, being transmitted by electronic communication channels and the Internet. The analysis of selection of places in text environment (TE, which can be replaced by word from the message is performed. Selection and replacement of words in the text environment is implemented basing on semantic analysis of text fragment, consisting of the inserted word, and its environment in TE. For implementation of such analysis is used concept of semantic parameters of words coordination and semantic value of separate word. Are used well-known methods of determination of values of these parameters. This allows moving from quality level to quantitative level analysis of text fragments semantics during their modification by word substitution. Invisibility of embedded messages is ensured by providing preset values of the semantic cooperation parameter deviations.

    Full Text Available This study is a syntactic analysis of text messages in English language used by University of Zimbabwe students. The study specifically focuses on sentences where there are omissions of pronouns, auxiliary verbs and where contractions occur. The study also analyzes the impact of sociolinguistic variables on the sentence structure of English language in text messages. The fifty respondents’ forwarded two messages each from their sent items on their cell phones to the researcher and to understand the factors triggering the syntactic structures the researcher carried out unstructured interviews. The data collected showed that cell phone texting has indeed been affected by the socio-economic factors and these factors trigger omissions of important elements of English language sentence structure such as ,pronouns, auxiliary verbs and contraction of phrases.

    Full Text Available Abstract Background Advances in communication technologies have dramatically changed how individuals access information and communicate. Recent studies have found that mobile phone text messages (SMS can be used successfully for short-term behaviour change. However there is no published information examining the acceptability, utility and efficacy of different characteristics of health promotion SMS. This paper presents the results of evaluation focus groups among participants who received twelve sexual health related SMS as part of a study examining the impact of text messaging for sexual health promotion to on young people in Victoria, Australia. Methods Eight gender-segregated focus groups were held with 21 males and 22 females in August 2008. Transcripts of audio recordings were analysed using thematic analysis. Data were coded under one or more themes. Results Text messages were viewed as an acceptable and 'personal' means of health promotion, with participants particularly valuing the informal language. There was a preference for messages that were positive, relevant and short and for messages to cover a variety of topics. Participants were more likely to remember and share messages that were funny, rhymed and/or tied into particular annual events. The message broadcasting, generally fortnightly on Friday afternoons, was viewed as appropriate. Participants said the messages provided new information, a reminder of existing information and reduced apprehension about testing for sexually transmitted infections. Conclusions Mobile phones, in particular SMS, offer health promoters an exciting opportunity to engage personally with a huge number of individuals for low cost. The key elements emerging from this evaluation, such as message style, language and broadcast schedule are directly relevant to future studies using SMS for health promotion, as well as for future health promotion interventions in other mediums that require short formats, such

    Background There is an ongoing effort to maximize educational material provided to residents who are in a time-constrained work environment. Mobile technology, principally smartphone applications and online modules, has shown educational promise. Intervention We developed a text-messaging program, Text4Peds, to assist residents with preparation for their pediatric board examinations. Goals were to assess (1) the feasibility of texting educational messages to residents, and (2) resident satisfaction and perceived usefulness of a texting program. Methods We conducted a prospective study of pediatrics and combined internal medicine-pediatrics residents. Messages derived from the most missed pediatric in-training examination questions were sent daily to residents. After 3 months, residents completed surveys that gauged their perception on the educational value of the text messages and the effect on their pediatric board preparation. Feasibility of the system was assessed as a total percentage of messages successfully received by residents. Results Of 55 residents, 35 (64%) participated in the program. Of 2534 messages sent out to participants, 2437 (96.2%) were delivered successfully. Positive comments cited the texting of board facts as a quick, helpful, daily study tool. Residents liked that messages were sent at 2:00 pm, and most felt that 1 to 5 messages per week was appropriate. Drawbacks included character restrictions of messages, content limitations, and the lack of a question-answer format. Conclusions An educational text message–based program was successfully implemented in our residency program. Messages were delivered with a high success rate, and residents found educational value in the messages. PMID:26140130

    Ayoola, Kehinde A.

    2014-02-01

    Full Text Available This paper is an application of Relevance Theory for the interpretation of short messaging service (SMS text messages emanating from Nigerian telecommunications companies to their subscribers. The aim of the research was to identify and describe the manipulative strategies employed by Nigerian telecommunications companies to induce subscribers to part with their money through sales promotion lotteries. 100 SMS texts were purposively extracted from the cell phones of randomly selected residents of Lagos Nigeria who had received promotional SMS text messages from three major Nigerian telecommunications companies. Using Sperber and Wilson's Relevance Theory (1995 as its theoretical framework, the paper described the manipulative use of SMS by Nigerian telecommunications companies. The analysis revealed that SMS text messages were encoded to achieve maximization of relevance through explicature and implicature; contextual implication and strengthening; and the reduction of processing effort through violating the maxim of truthfulness and the creative use of graphology. The paper concludes that SMS text-messages were used manipulatively by Nigerian telecommunications companies to earn indirect income from sales promotion lottery.

  6. A Wireless Text Messaging System Improves Communication for Neonatal Resuscitation.

    Hughes Driscoll, Colleen A; Schub, Jamie A; Pollard, Kristi; El-Metwally, Dina

    Handoffs for neonatal resuscitation involve communicating critical delivery information (CDI). The authors sought to achieve ≥95% communication of CDI during resuscitation team requests. CDI included name of caller, urgency of request, location of delivery, gestation of fetus, status of amniotic fluid, and indication for presence of the resuscitation team. Three interventions were implemented: verbal scripted handoff, Spök text messaging, and Engage text messaging. Percentages of CDI communications were analyzed using statistical process control. Following implementation of Engage, the communication of all CDI, except for indication, was ≥95%; communication of indication occurred 93% of the time. Control limits for most CDI were narrower with Engage, indicating greater reliability of communication compared to the verbal handoff and Spök. Delayed resuscitation team arrival, a countermeasure, was not higher with text messaging compared to verbal handoff ( P = 1.00). Text messaging improved communication during high-risk deliveries, and it may represent an effective tool for other delivery centers.

    Hospitals today are experiencing major changes in their clinical communication workflows as conventional numeric paging and face-to-face verbal conversations are being replaced by computer mediated communication systems. In this paper, we highlight the importance of understanding this transition and discuss some of the impacts that may emerge when verbal clinical conversations are replaced by short text messages. In-depth interviews (n=108) and non-participatory observation sessions (n=260h) were conducted on the General Internal Medicine wards at five academic teaching hospitals in Toronto, Canada. From our analysis of the qualitative data, we identified two major themes. De-contextualization of complex issues led to an increase in misinterpretation and an increase in back and forth messaging for clarification. Depersonalization of communication was due to less verbal conversations and face-to-face interactions and led to a negative impact on work relationships. Text-based communication in hospital settings led to the oversimplification of messages and the depersonalization of communication. It is important to recognize and understand these unintended consequences of new technology to avoid the negative impacts to patient care and work relationships.

    With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient-clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. Mobile texting messaging has the potential to play an important role in patient-clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication.

    Text messaging is a powerful communication tool for public health purposes, particularly because of the potential to customize messages to meet individuals' needs. However, using text messaging to send personal health information requires analysis of laws addressing the protection of electronic health information. The Health Insurance Portability and Accountability Act (HIPAA) Security Rule is written with flexibility to account for changing technologies. In practice, however, the rule leads to uncertainty about how to make text messaging policy decisions. Text messaging to send health information can be implemented in a public health setting through 2 possible approaches: restructuring text messages to remove personal health information and retaining limited personal health information in the message but conducting a risk analysis and satisfying other requirements to meet the HIPAA Security Rule.

    Human papillomavirus (HPV) vaccination is routinely recommended for U.S. adolescents ages 11 to 12 years, yet vaccine coverage remains low. Text message HPV immunization reminders to parents have been effective with increasing uptake, but text messages directly to adolescents in order to increase HPV vaccination uptake are unknown. The purpose of this study was to examine the acceptability of text messages about HPV vaccination and message preferences among adolescents. Middle school students (n = 43) assisted in designing text messages to promote HPV vaccine among their peers. Through seven focus groups and two in-class surveys, we assessed students’ knowledge of HPV vaccine, use of texting, and preferences for text messages and sources. The average age of participants was 13 years, and all were White (17 males, 26 females) in this rural setting. More than 70% used text messaging with a cell phone. The text message with the best composite score (M = 2.33, SD = 0.72) for likeability, trustworthiness, and motivation to seek more information was a gain frame emphasizing reduction in HPV infection if vaccinated against HPV. Text messages with lower scores emphasized threats of disease if not vaccinated. Participants (68%) preferred doctors as their information source. Text messaging to adolescents may be a strategy to improve HPV knowledge and vaccination. PMID:25258431

    Full Text Available This article examined how higher education students used text and instant messaging for academic purposes with their peers and faculty. Specifically, comfort level, frequency of use, usefulness, reasons for messaging and differences between peer-to-peer and peer-to-instructor interactions were examined. Students noted that they were very comfortable with using both text and instant messaging. Text messaging was used weekly with instructors and daily with peers. Instant messaging was used rarely with instructors but weekly with peers. Students rated text messaging as very useful and instant messaging as moderately useful for academic purposes. Key reasons cited for using both text and instant messaging included saving time, resolving administrative issues, convenience and ease of use. Text messaging appears to be the preferred mode of communication for students with respect to communicating with both peers and instructors. It is concluded that both text and instant messaging are useful and viable tools for augmenting student's communication among peers and faculty in higher education.

    Abstract Background: With the increasing penetration of digital mobile devices among adolescents, mobile texting messaging is emerging as a new channel for patient–clinician communication for this population. In particular, it can promote active communication between healthcare clinicians and adolescents with asthma. However, little is known about the content of the messages exchanged in medical encounters via mobile text messaging. Therefore, this study explored the content of text messaging between clinicians and adolescents with asthma. Materials and Methods: We collected a total of 2,953 text messages exchanged between 5 nurse case managers and 131 adolescents with asthma through a personal digital assistant. The text messages were coded using a scheme developed by adapting categories from the Roter Interaction Analysis System. Results: Nurse case managers sent more text messages (n=2,639) than adolescents with asthma. Most messages sent by nurse case managers were targeted messages (n=2,475) directed at all adolescents with asthma, whereas there were relatively few tailored messages (n=164) that were created personally for an individual adolescent. In addition, both targeted and tailored messages emphasized task-focused behaviors over socioemotional behaviors. Likewise, text messages (n=314) sent by adolescents also emphasized task-focused over socioemotional behaviors. Conclusions: Mobile texting messaging has the potential to play an important role in patient–clinician communication. It promotes not only active interaction, but also patient-centered communication with clinicians. In order to achieve this potential, healthcare clinicians may need to focus on socioemotional communication as well as task-oriented communication. PMID:25401324

    To understand adolescents' perspectives on the use of a preventive sexual health text messaging service. Twenty-six adolescents aged 15-20 years old were recruited from two teen clinics in Los Angeles County to participate in focus groups. Three focus groups were held. Discussions focused on the content of the weekly text messages sent by a service called the Hookup, as well as the acceptability of using text messaging to relay sexual health education to adolescents. Codes and themes were developed from transcripts using standard constant comparison methods. Participants enjoyed receiving weekly text messages related to sexual health. They linked their enjoyment to the message content being informative (providing relevant and new information), simple (automatically limited to small words and short phrases), and sociable (easily able to be shared with friends). Participants also pointed to the convenience and ubiquity of text messaging and generally felt that cost of messages was not a concern. Most felt that text messaging provided a sense of privacy for learning about sensitive health topics, although a few expressed concerns about stigma from peers' seeing the messages. Teens may face several barriers to accessing reliable, useful, and age-appropriate information and services for their health. The use of text messaging is an innovative way to engage teens in preventive health learning and practices. Text messaging may allow efficient delivery of health messages and may offer a discreet way for teens to learn important health information, especially for sensitive topics like sexual health.

    Text messaging has become more prevalent in general practice as a tool with which to communicate with patients. The main objectives were to assess the extent, growth, and perceived risks and benefits of text messaging by GPs to communicate with patients, and assess patients' attitudes towards receiving text messages from their GP. A mixed methods study, using surveys, a review, and a focus group, was conducted in both urban and rural practices in the south-west of Ireland. A telephone survey of 389 GPs was conducted to ascertain the prevalence of text messaging. Subsequently, the following were also carried out: additional telephone surveys with 25 GPs who use text messaging and 26 GPs who do not, a written satisfaction survey given to 78 patients, a review of the electronic information systems of five practices, and a focus group with six GPs to ascertain attitudes towards text messaging. In total, 38% (n = 148) of the surveyed GPs used text messaging to communicate with patients and 62% (n = 241) did not. Time management was identified as the key advantage of text messaging among GPs who used it (80%; n = 20) and those who did not (50%; n = 13). Confidentiality was reported as the principal concern among both groups, at 32% (n = 8) and 69% (n = 18) respectively. Most patients (99%; n = 77) were happy to receive text messages from their GP. The GP focus group identified similar issues and benefits in terms of confidentiality and time management. Data were extracted from the IT systems of five consenting practices and the number of text messages sent during the period from January 2013 to March 2016 was generated. This increased by 40% per annum. Collaborative efforts are required from relevant policymakers to address data protection and text messaging issues so that GPs can be provided with clear guidelines to protect patient confidentiality. © British Journal of General Practice 2017.

    African American young adults are at high risk of HIV infection during their lifetimes, and the male condom remains the best method of prevention. Efforts to increase condom use should address the barrier of condom negotiation. We conducted a thematic analysis of qualitative, semistructured interviews with African American young adults to examine their use of text messaging for requesting human immunodeficiency virus (HIV) or sexually transmitted infection (STI) testing and condom use within the larger context of general sexual communication using text messages. Text messaging gave participants a level of comfort and disinhibition to discuss sexual topics and negotiate sexual safety. Benefits of text messages included ease of communication, privacy, and increased ability to express condom desires. Difficulties reflected the potential relationship implications of suggesting HIV/STI testing and condom use. Condom negotiation strategies using text messages also mirrored those found to be used in face-to-face communication.

  5. Two-way text messaging: an interactive mobile learning environment in higher education

    Full Text Available Short messaging service (SMS is perhaps the most popular mobile technology prevalent among students in higher education due to its ubiquitous nature and the capability of two-way communication. However, a major limitation in two-way text messaging is sending back a part of received data with the reply message. This limitation results in users of a mobile learning environment being unable to reply back to the correct destination. This article presents a two-way text messaging system that can be integrated into a learning management system (LMS to provide an interactive learning experience to the user community. Initially, a database is integrated into the LMS that holds message information such as recipient's phone number, message body and user data header. A specific port associated with the SMS is used to conceal and exchange data of a particular course unit. Subsequently, software in the student's mobile device captures this message and sends back the reply message to the appropriate course unit allowing both teachers and students to view messages sent and replies received pertaining to a particular course. Results indicate the educational impact of the proposed system in improving the learning environment and benefits it offers to the community in a campus-wide implementation.

    mHealth interventions that incorporate text messages have great potential to increase receipt of preventive health services such as colorectal cancer screening. However, little is known about older adult perspectives regarding the receipt of text messages from their health care providers. To assess whether older adults would value and access text messages from their physician's practice regarding colorectal cancer screening. We conducted four focus groups with 26 adults, aged 50 to 75 years, who had either recently completed or were overdue for colorectal cancer screening. A trained moderator followed a semistructured interview guide covering participant knowledge and attitudes regarding colorectal cancer screening, potential barriers to colorectal cancer screening, attitudes about receiving electronic communications from a doctor's office, and reactions to sample text messages. Participant responses to three primary research questions were examined: (1) facilitators and barriers to colorectal cancer screening, (2) attitudes toward receiving text messages from providers, and (3) characteristics of appealing text messages. Two themes related to facilitators of colorectal cancer screening were perceived benefits/need and family experiences and encouragement. Themes related to barriers included unpleasantness, discomfort, knowledge gaps, fear of complications, and system factors. Four themes emerged regarding receipt of text messages from health care providers: (1) comfort and familiarity with technology, (2) privacy concerns/potential for errors, (3) impact on patient-provider relationship, and (4) perceived helpfulness. Many participants expressed initial reluctance to receiving text messages but responded favorably when shown sample messages. Participants preferred messages that contained content that was important to them and were positive and reassuring, personalized, and friendly to novice texters (eg, avoided the use of texting shorthand phrases and complicated

    Text messages improve health outcomes for adults engaged in weight management. Little is known about whether text messaging parents of children enrolled in obesity treatment will improve child health. We conducted a 2-group randomized controlled study among 101 children aged 5-12 and their parent/guardian enrolling in tertiary-care obesity treatment. Participants were randomized to standard care or standard care plus daily motivational interviewing-based text messages. The primary outcome was change in child BMI at 3 months. Secondary outcomes included feasibility, health behaviors, attrition, motivation, and parent BMI. We enrolled 101 parent-child dyads and retained 81% to 3-month follow-up. Child participants had a mean age of 9.9 years, and baseline BMI of 30.5 kg/m2. Half (48%) of participants were Black, and 64% of parent participants had a high school equivalent education or less. Ninety-nine percent of parents owned a mobile device with unlimited text messaging. Parents responded to 80% of texts, and 95% felt the texts "always" or "almost always" helped them make a good health decision. We observed no between-group difference in child zBMI from baseline to 3 months (0.0 vs. 0.2, p = 0.2). Intervention participants had significantly better adherence to clinic visits (3.3 visits vs. 2.1 visits/3 months, p text messages did not significantly change child BMI. However, texting significantly reduced attrition for treatment visits. Nearly all parents in this racially diverse, low-income sample engaged in daily text messaging, making this a feasible approach.

    2011-01-01

    The increasing popularity of text messaging has made this mode of communication the preferred interaction portal for teens. Virtually every teenager has a cell phone with an unlimited text messaging plan. Text messaging easily facilitates communication between individuals without much interruption into daily life. After administering a survey to ten early adolescents and ten late adolescents, the effects of this technology are manifested across many developmental characteristics. Communication, responsibility, and relationships all seem to be negatively influenced by the use of text messaging. This pattern is seen in both early and late adolescent groups. Developmentally, different characteristic features categorize early and late adolescence, yet it seems the use of text messaging is propelling early adolescence forward by removing the consequences of awkward face-to-face interactions. This early onset of late adolescence results in having very young teens, 12 and 13 year olds, showing increased interest in romantic relationships and sexual exploration. The anxiety and uneasiness felt by early teens about speaking with others has led to deficits in the ability to communicate in social settings, which could prove troublesome later. This study looks at only a few developmental issues associated with text messaging use among teens. It would be relevant and appropriate to study other ways that text messaging affects our youth in addition to exploring the more long-term effects of using this technology.

    Short message service (SMS) text messaging is an efficient form of communication and pervasive in health care, but may not securely protect patient information. It is unclear if resident providers are aware of the security concerns of SMS text messaging when communicating about patient care. We sought to compare residents' preferences for SMS text messaging compared with other forms of in-hospital communication when considering security versus ease of use. This study was a cross-sectional multi-institutional survey of internal medicine residents. Residents ranked different communication modalities based on efficiency, ease of use, and security using a Likert scale. Communication options included telephone, email, hospital paging, and SMS text messaging. Respondents also reported whether they had received confidential patient identifiers through any of these modalities. SMS text messaging was preferred by 71.7% (94/131) of respondents because of its efficiency and by 79.8% (103/129) of respondents because of its ease of use. For security, 82.5% (104/126) of respondents preferred the hospital paging system, whereas only 20.6% (26/126) of respondents preferred SMS text messaging for secure communication. In all, 70.9% (93/131) of respondents reported having received patient identifiers (first and/or last name), 81.7% (107/131) reported receiving patient initials, and 50.4% (66/131) reported receiving a patient's medical record number through SMS text messages. Residents prefer in-hospital communication through SMS text messaging because of its ease of use and efficiency. Despite security concerns, the majority of residents reported receiving confidential patient information through SMS text messaging. For providers, it is possible that the benefits of improved in-hospital communication with SMS text messaging and the presumed improvement in the coordination and delivery of patient care outweigh security concerns they may have. The tension between the security and

    We examined the use of tailored messages sent to the mobile phones of obese adolescents enrolled in a weight-management programme, as a means of increasing adherence. The feasibility study was conducted in three phases: (1) a library of 90 messages was developed about five weight-related behaviours; (2) a computer application was developed to tailor these messages to participants' characteristics; the SMS messages (text and images) were sent to mobile phones daily; (3) a three-month trial of the intervention was performed with 20 adolescents. Semi-structured interviews were conducted to assess the participants' perceptions of the intervention and the participants', providers' and computer consultants' reports about technology performance. These interviews revealed that participants were enthusiastic about the intervention and most found the messages to be personally relevant. The favourite messages were meal suggestions and recipe ideas. The computer tailoring application performed faultlessly and messages were delivered on schedule and in the desired sequence. Computerized tailored text messaging is a feasible adjunct to multidisciplinary obesity treatment and is acceptable to adolescents as an enjoyable means of improving their adherence to healthy lifestyle practices.

    Young adults are a particularly hard to reach group using conventional health promotion practices as they do not see nutrition messages as personally relevant to them. Text messaging (short message service, SMS) offers an innovative approach to reaching young adults to support and promote dietary behavior change. The aim of this study was to develop and test tonal preferences for nutrition text messages among young adults using focus groups. A total of 39 young adults aged 18-30 years residing in Perth, Western Australia participated in four focus groups. Participants briefly discussed their perception of healthy eating and their responses to messages about increasing fruit and vegetables, and reducing "junk food" and alcohol intake. They ranked their preference for 15 nutrition messages across 3 dietary behaviors (fruit and vegetables, junk food, and alcohol) with 5 different message tones (authoritative, empathetic, generation Y, solutions, and substitutions) and identified the messages most likely to persuade young adults to change their diet. A 5-point ranking of the nutrition messages was from the most likely to least likely to persuade (1-5). The focus groups were conducted by a trained facilitator and observer and were recorded. Data driven content analysis was used to explore themes. Tonal preferences and potential motivators were collated and frequencies presented. Participants ranked offering substitutes (29%, 11/39) and using empathy (22%, 9/39) as the most persuasive message techniques in improving diets of young adults, with low responses for Generation Y (17%, 7/39), solutions (17%, 7/39), and authoritative (15%, 6/39) tones. Females were more likely to consider substitution messages persuasive (35%, 7/20) compared with males (22%, 4/19). A greater proportion of males compared with females considered authoritative messages persuasive: (22%, 4/19) compared with (7%, 1/20). There is a strong preference for a substitution tone for fruit and vegetable

    Text messaging has successfully supported smoking cessation. This study compares a mobile application with text messaging to support smoking cessation. Young adult smokers 18-30 years old (n = 102) participated in a randomized pretest-posttest trial. Smokers received a smartphone application (REQ-Mobile) with short messages and interactive tools or a text messaging system (onQ), managed by an expert system. Self-reported usability of REQ-Mobile and quitting behavior (quit attempts, point-prevalence, 30-day point-prevalence, and continued abstinence) were assessed in posttests. Overall, 60% of smokers used mobile services (REQ-Mobile, 61%, mean of 128.5 messages received; onQ, 59%, mean of 107.8 messages), and 75% evaluated REQ-Mobile as user-friendly. A majority of smokers reported being abstinent at posttest (6 weeks, 53% of completers; 12 weeks, 66% of completers [44% of all cases]). Also, 37% (25%of all cases) reported 30-day point-prevalence abstinence, and 32% (22% of all cases) reported continuous abstinence at 12 weeks. OnQ produced more abstinence (pMobile. Use of both services predicted increased 30-day abstinence at 12 weeks (used, 47%; not used, 20%; p = 0.03). REQ-Mobile was feasible for delivering cessation support but appeared to not move smokers to quit as quickly as text messaging. Text messaging may work better because it is simple, well known, and delivered to a primary inbox. These advantages may disappear as smokers become more experienced with new handsets. Mobile phones may be promising delivery platforms for cessation services using either smartphone applications or text messaging.

    Full Text Available African American girls are at a greater risk of obesity than their nonminority peers. Parents have the primary control over the home environment and play an important role in the child obesity prevention. Obesity prevention programs to help parents develop an obesity-preventive home environment are needed. The purpose of this study was to collect formative research from parents of 8–10-year old African American girls about perceptions, expectations, and content for a text messaging based program. Mothers (n = 30 participated in surveys and interviews to inform message development and content. A professional expert panel (n = 10 reviewed draft text messages via a survey. All the mothers reported owning a cellphone with an unlimited texting plan, and they used their cellphones for texting (90.0% and accessing the Internet (100.0%. The majority were interested in receiving text messages about healthy eating and physical activity (86.7%. Interviews confirmed survey findings. One hundred and seven text messages promoting an obesity-preventive home environment were developed. The expert panel and parents reported positive reactions to draft text messages. This research provides evidence that mobile health (mHealth interventions appeal to parents of African American girls and they have ready access to the technology with which to support this approach.

    Text messaging while driving can be distracting and significantly increases the risk of being involved in a collision. Compared to freeway driving, driving in a tunnel environment introduces factors that may interact with driver attentional resources to exacerbate the effects of distraction on driving safety. With planning and design of the 18km Stockholm Bypass tunnel ongoing, and because of the potentially devastating consequences of crashes in long tunnels, it is critical to assess the effects of driver distraction in a tunnel environment. Twenty-four participants (25-50 years) drove in simulated highway and tunnel road environments while reading and writing text messages using their own mobile phones. As expected, compared to driving alone, text messaging was associated with decrements in driving performance and visual scanning behavior, and increases in subjective workload. Speeds were slower compared to baseline (no text-messaging) driving when participants performed the text-messaging tasks in the tunnel environment compared to the freeway, suggesting that drivers may have attempted to compensate more for the increased text-messaging-related workload when they were in the tunnel. On the other hand, increases in lane deviation associated with the most complex text-messaging task were more pronounced in the tunnel compared to on the freeway. Collectively, results imply that driver distraction in tunnels is associated with generally similar driving decrements as freeway driving; however, the potential consequences of these decrements in tunnels remain significantly more serious. Future research should attempt to elucidate the nature of any differential compensatory behavior in tunnel, compared to freeway, driving. In the meantime, drivers should be advised to refrain from text messaging, especially when driving in tunnels. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Several post-suicide prevention strategies such as sending postcards or making phone calls have been used to keep in contact with suicide attempters. The continuity of care has been beneficial to the prevention of post-acute suicidal behaviors. The aim of the study was to evaluate the technical feasibility and acceptability of text messaging outreach in post-acute suicide attempters. Eighteen post-suicidal patients were included in a prospective, monocentric, open-label, 2 months pilot study. The text messages were sent from the intranet program that we specially developed for the study. Technical feasibility of this text message intervention was evaluated by the analysis of text message reports. Acceptability of such intervention was evaluated by a standardized phone interview. Our study showed that receiving text messages sent from an intranet program after a suicide attempt is technically possible. This post-crisis outreach program was accepted by the patients who found it to have a positive preventive impact. Text messaging outreach offers several advantages such as lower cost, and easier utilization compared to current post-acute care strategies. We suggest further randomized controlled trials in a large sample of suicidal patients to assess the efficacy of this novel outreach tool for prevention of post-acute suicide.

    Few studies have evaluated text message content preferences to support evidence-based treatment approaches for opioid use disorders, and none in primary care office-based buprenorphine treatment settings. This study assessed the acceptability and preferences for a tailored text message intervention in support of core office-based buprenorphine treatment medical management components (e.g., treatment adherence, encouraging abstinence, 12-step group participation, motivational interviewing, and patient-provider communication as needed). There were 97 patients enrolled in a safety net office-based buprenorphine treatment program who completed a 24-item survey instrument that consisted of multiple-choice responses, 7-point Likert-type scales, binomial "Yes/No" questions, and open-ended responses. The sample was predominately male (81%), had an average age of 46 years, and was diverse (64% ethnic/racial minorities); 56% lacked stable employment. Respondents were interested in receiving text message appointment reminders (90%), information pertaining to their buprenorphine treatment (76%), supportive content (70%), and messages to reduce the risk of relapse (88%). Participants preferred to receive relapse prevention text messages during all phases of treatment: immediately after induction into buprenorphine treatment (81%), a "few months" into treatment (57%), and after discontinuing buprenorphine treatment (72%). Respondents also expressed interest in text message content enhancing self-efficacy, social support, and frequent provider communication to facilitate unobserved "home" induction with buprenorphine. Older participants were significantly less receptive to receiving text message appointment reminders; however, they were as interested in receiving supportive, informational, and relapse prevention components compared to younger respondents. Implications for integrating a text message support system in office-based buprenorphine treatment are discussed.

    To determine whether a smoking cessation service using mobile phone text messaging is as effective for Maori as non-Maori. A single-blind randomised controlled trial was undertaken with recruitment targeted to maximise the participation of young Maori. The intervention included regular, personalised text messages providing smoking cessation advice, support, and distraction. Maori text messages related to Maori language, support messages (in Maori and English) and information on Maori traditions. Text messaging was free for 1 month. After 6 weeks, the number of messages reduced from 5 per day to 3 per week until the 26-week follow-up. Participants included 355 Maori and 1350 non-Maori. Maori in the intervention group were more likely to report quitting (no smoking in the past week) at 6 weeks (26.1%) than those in the control group (11.2%) RR 2.34, 95% CI: 1.44-3.79. There was no significant difference between the RR for Maori and that for non-Maori (RR: 2.16, 95%CI: 1.72-2.71). A mobile phone-based cessation programme was successful in recruiting young Maori, and was shown to be as effective for Maori as non-Maori at increasing short-term self-reported quit rates. This shows clear potential as a new public health initiative.

    Background Tobacco use is one of the leading preventable global health problems producing nearly 6 million smoking-related deaths per year. Interventions delivered via text messaging (short message service, SMS) may increase access to educational and support services that promote smoking cessation across diverse populations. Objective The purpose of this meta-analysis is to (1) evaluate the efficacy of text messaging interventions on smoking outcomes, (2) determine the robustness of the evidence, and (3) identify moderators of intervention efficacy. Methods Electronic bibliographic databases were searched for records with relevant key terms. Studies were included if they used a randomized controlled trial (RCT) to examine a text messaging intervention focusing on smoking cessation. Raters coded sample and design characteristics, and intervention content. Summary effect sizes, using random-effects models, were calculated and potential moderators were examined. Results The meta-analysis included 20 manuscripts with 22 interventions (N=15,593; 8128 (54%) women; mean age=29) from 10 countries. Smokers who received a text messaging intervention were more likely to abstain from smoking relative to controls across a number of measures of smoking abstinence including 7-day point prevalence (odds ratio (OR)=1.38, 95% confidence interval (CI)=1.22, 1.55, k=16) and continuous abstinence (OR=1.63, 95% CI=1.19, 2.24, k=7). Text messaging interventions were also more successful in reducing cigarette consumption relative to controls (d+=0.14, 95% CI=0.05, 0.23, k=9). The effect size estimates were biased when participants who were lost to follow-up were excluded from the analyses. Cumulative meta-analysis using the 18 studies (k=19) measuring abstinence revealed that the benefits of using text message interventions were established only after only five RCTs (k=5) involving 8383 smokers (OR=1.39, 95% CI=1.15, 1.67, Pinterventions for smoking abstinence (OR=1.37, 95% CI=1.25, 1

    To assess caloric knowledge of participants and determine if an e-mail and/or text message intervention could increase knowledge of recommended daily caloric intake. Randomized, control trial. Johns Hopkins Hospital Cobblestone Café. The 246 participants reported eating at the Café at least twice/week. Participants randomized to control, e-mail, or text condition. The text and e-mail conditions received a message on four consecutive Mondays stating the recommended daily caloric intake. Knowledge of the government reference value of 2,000 calories. Intention-to-treat analysis was conducted. Multivariate logistic regression examined the effectiveness of text and e-mail messaging for improving knowledge of the government calorie reference value. Baseline awareness of the daily calorie reference value in study population was low. Participants in the text message condition were twice as likely to know the government calorie reference value compared to controls (p = .047, odds ratio = 2.2, 95% confidence interval [1.01, 4.73]). No significant differences were found for the e-mail condition (p = .5). Many people do not know the daily recommended caloric intake. Public education on the government calorie reference value is necessary for menu-labeling interventions to be more effective. Weekly text messaging can serve as an effective modality for delivering calorie information and nutrition education. © 2014 Society for Public Health Education.

    Students at community colleges comprise nearly half of all U.S. college students and show higher risk of heavy drinking and related consequences compared to students at 4-year colleges, but no alcohol safety programs currently target this population. To examine the feasibility, acceptability, and preliminary efficacy of an alcohol risk-reduction program delivered through text messaging designed for community college (CC) students. Heavy drinking adult CC students (N=60) were enrolled and randomly assigned to the six-week active intervention (Text Message Alcohol Program: TMAP) or a control condition of general motivational (not alcohol related) text messages. TMAP text messages consisted of alcohol facts, strategies to limit alcohol use and related risks, and motivational messages. Assessments were conducted at baseline, week 6 (end of treatment) and week 12 (follow up). Most participants (87%) completed all follow up assessments. Intervention messages received an average rating of 6.8 (SD=1.5) on a 10-point scale. At week six, TMAP participants were less likely than controls to report heavy drinking and negative alcohol consequences. The TMAP group also showed significant increases in self-efficacy to resist drinking in high risk situations between baseline and week six, with no such increase among controls. Results were maintained through the week 12 follow up. The TMAP alcohol risk reduction program was feasible and highly acceptable indicated by high retention rates through the final follow up assessment and good ratings for the text message content. Reductions in multiple outcomes provide positive indications of intervention efficacy. Copyright © 2016. Published by Elsevier Ltd.

    Intensity of depressive symptoms could be exacerbated due to the paucity of appropriate treatments. We assessed the effectiveness of bibliotherapy and text messaging, which aimed at amelioration of patient's behavior and consciousness, which could lead to suicide prevention. This was a randomized clinical trial implemented in rural health centers of Isfahan district (Iran). Health centers were assigned in three trials consisting of the booklet, text messaging, and control groups. Each group consisted of 70 patients. Inclusion criteria were being affected by depressive symptom, bibliotherapy could efficiently decrease the intensity of depressive symptoms. Nevertheless, in comparison with our booklet trial, the text messaging group achieved neither durable nor significant success; thus, bibliotherapy could be utilized as a complementary methodology aiming depression treatment.

    There is a need for innovation in both the enrollment of pregnant smokers in smoking cessation treatment programs and in the types of treatments offered. The study tests whether an interactive and intensive text messaging program, Quit4baby, can promote smoking cessation for pregnant women already enrolled in a health text messaging program, Text4baby. Between July 2015 and February 2016, a total of 35,957 recruitment text messages were sent to Text4baby subscribers. Eligible pregnant smokers were enrolled and randomized to receive Text4baby (control) or Text4baby and Quit4baby (intervention; N=497). Participants were surveyed at 1 month, 3 months, and 6 months post-enrollment, and saliva samples were collected at 3 months for biochemical verification of smoking status. Data were collected from 2015 to 2016 and analyzed in 2016. Using an intention-to-treat analysis, 28.80% of the intervention group and 15.79% of the control group reported not smoking in the past 7 days at 1 month (ptext messaging program in the short term and late in pregnancy, but not in the postpartum period.

    We tested the feasibility and effectiveness of an alcohol counseling intervention delivered via personalized text messages for college students with problem alcohol use. College students aged 18-23 completed online substance use and mental health questionnaires that served as a screening tool for problem alcohol use. We invited students who screened positive to be randomized to intervention (n = 8) or control groups (n = 10) and assessed them at 1 month after they received their last text message. The intervention group received between four and six text messages daily for 4 days that required brief participant responses during the week following the web-based baseline assessment. Participants in the intervention group could also request booster texts for additional support. We personalized all texts, using data collected at baseline. Using a repeated measures ANOVA, we found that compared to the control group, the intervention group increased in readiness to change from baseline to follow-up (p alcohol use. These exploratory results indicate that the automated texting program we developed works well with college students and that text messaging as a means to deliver preventive interventions is a promising delivery platform.

    Cognitive Behavioral Therapy (CBT) for depression is efficacious, but effectiveness is limited when implemented in low-income settings due to engagement difficulties including nonadherence with skill-building homework and early discontinuation of treatment. Automated messaging can be used in clinical settings to increase dosage of depression treatment and encourage sustained engagement with psychotherapy. The aim of this study was to test whether a text messaging adjunct (mood monitoring text messages, treatment-related text messages, and a clinician dashboard to display patient data) increases engagement and improves clinical outcomes in a group CBT treatment for depression. Specifically, we aim to assess whether the text messaging adjunct led to an increase in group therapy sessions attended, an increase in duration of therapy attended, and reductions in Patient Health Questionnaire-9 item (PHQ-9) symptoms compared with the control condition of standard group CBT in a sample of low-income Spanish speaking Latino patients. Patients in an outpatient behavioral health clinic were assigned to standard group CBT for depression (control condition; n=40) or the same treatment with the addition of a text messaging adjunct (n=45). The adjunct consisted of a daily mood monitoring message, a daily message reiterating the theme of that week's content, and medication and appointment reminders. Mood data and qualitative responses were sent to a Web-based platform (HealthySMS) for review by the therapist and displayed in session as a tool for teaching CBT skills. Intent-to-treat analyses on therapy attendance during 16 sessions of weekly therapy found that patients assigned to the text messaging adjunct stayed in therapy significantly longer (median of 13.5 weeks before dropping out) than patients assigned to the control condition (median of 3 weeks before dropping out; Wilcoxon-Mann-Whitney z=-2.21, P=.03). Patients assigned to the text messaging adjunct also generally

    Suicidal behaviour and deliberate self-harm are common among adults. Research indicates that maintaining contact either via letter or postcard with at-risk adults following discharge from care services can reduce reattempt risk. Feasibility trials demonstrated that intervention through text message was also effective in preventing suicide repetition amongst suicide attempters. The aim of the current study is to investigate the effect of text message intervention versus traditional treatment on reducing the risk of suicide attempt repetition among adults after self-harm. The study will be a 2-year multicentric randomized controlled trial conducted by the Brest University Hospital, France. Participants will be adults discharged after self-harm, from emergency services or after a short hospitalization. Participants will be recruited over a 12-month period. The intervention is comprised of an SMS that will be sent at h48, D7, D15 and monthly. The text message enquires about the patients' well-being and includes information regarding individual sources of help and evidence-based self help strategies. Participants will be assessed at the baseline, month 6 and 13. As primary endpoint, we will assess the number of patients who reattempt suicide in each group at 6 months. As secondary endpoints, we will assess the number of patients who reattempt suicide at 13 month, the number of suicide attempts in the intervention and control groups at 6 and 13 month, the number of death by suicide in the intervention and control groups at month 6 and 13. In both groups, suicidal ideations, will be assessed at the baseline, month 6 and 13. Medical costs and satisfaction will be assessed at month 13. This paper describes the design and deployment of a trial SIAM; an easily reproducible intervention that aims to reduce suicide risk in adults after self-harm. It utilizes several characteristics of interventions that have shown a significant reduction in the number of suicide reattempts. We

    Background: Intensity of depressive symptoms could be exacerbated due to the paucity of appropriate treatments. We assessed the effectiveness of bibliotherapy and text messaging, which aimed at amelioration of patient's behavior and consciousness, which could lead to suicide prevention. Methods: This was a randomized clinical trial implemented in rural health centers of Isfahan district (Iran). Health centers were assigned in three trials consisting of the booklet, text messaging, and control groups. Each group consisted of 70 patients. Inclusion criteria were being affected by depressive symptom, <18 years, and cell phone accessibility. Mental retardation, drug and alcohol abuse, visual disability, dementia, suicide attempt history, electrotherapy, and receiving psychological interventions were our not met criteria. Our patient outcomes comprised intensity of depressive symptom and treatment compliance. The first two trials were requested to study instructive booklets in 30 days while the second cohort was demanded to study the booklet in accordance with the daily delivered text messaging. Results: Out of 210 individuals, 198 patients finished this study. The intensity of depressive symptom was significantly affected through time and group factors as well as time-group interaction (F = 12.30, P < 0.001). Based on treatment compliance, the interactive effect of group factor and the time factor was statistically significant. Conclusions: It seems that bibliotherapy could efficiently decrease the intensity of depressive symptoms. Nevertheless, in comparison with our booklet trial, the text messaging group achieved neither durable nor significant success; thus, bibliotherapy could be utilized as a complementary methodology aiming depression treatment.

    Health care-associated infections are a major worldwide public health issue. Hand hygiene is a major component in the prevention of pathogen transmission in hospitals, and hand hygiene adherence by health care workers is low in many studies. We report an intervention using text messages as reminders and feedback to improve hand hygiene adherence. The study is a historical comparison proof-of-concept study. Eighteen health care workers were monitored during 12 months by a radiofrequency identification system. Afterward we sent 2 types of text messages, congratulation or encouragement, and we studied the evolution of hand hygiene adherence. We recorded 15,723 hand hygiene opportunities, 8,973 before intervention and 6,750 during and after the intervention. Using a multilevel logistic regression analysis, we found a significant increase in hand hygiene adherence during the intervention (odds ratio, 1.68) compared with the historical period. Despite limitations due to the type of study, a text message encouraging personnel to be more vigilant is effective in increasing hand hygiene adherence in health care workers. Text message feedback should be incorporated into multimodal approaches for improving hand hygiene compliance.

    We examined the feasibility of using mobile phone text messaging with homeless veterans to increase their engagement in care and reduce appointment no-shows. We sent 2 text message reminders to participants (n = 20) before each of their outpatient appointments at an urban Veterans Affairs medical center. Evaluation included pre- and postsurvey questionnaires, open-ended questions, and review of medical records. We estimated costs and savings of large-scale implementation. Participants were satisfied with the text-messaging intervention, had very few technical difficulties, and were interested in continuing. Patient-cancelled visits and no-shows trended downward from 53 to 37 and from 31 to 25, respectively. Participants also experienced a statistically significant reduction in emergency department visits, from 15 to 5 (difference of 10; 95% confidence interval [CI]  = 2.2, 17.8; P = .01), and a borderline significant reduction in hospitalizations, from 3 to 0 (difference of 3; 95% CI = -0.4, 6.4; P = .08). Text message reminders are a feasible means of reaching homeless veterans, and users consider it acceptable and useful. Implementation may reduce missed visits and emergency department use, and thus produce substantial cost savings.

    Patient-reported outcome (PRO) instruments allow patients to interpret their health and are integral in evaluating orthopedic treatments and outcomes. The purpose of this study was to define: (1) correlation between PROs collected by automated delivery of text messages on mobile phones compared with paper delivery; and (2) patient use characteristics of a technology platform utilizing automated delivery of text messages on mobile phones. Paper versions of the 12-Item Short Form Health Survey (SF-12) and the short form of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) were completed by patients in orthopedic hand and upper extremity clinics. Over the next 48 hours, the same patients also completed the mobile phone portion of the study outside of the clinic which included text message delivery of the SF-12 and QuickDASH, assigned in a random order. Correlations between paper and text message delivery of the 2 PROs were assessed. Among 72 patients, the intraclass correlation coefficient (ICC) between the written and mobile phone delivery of QuickDASH was 0.91 (95% confidence interval [CI], 0.85-0.95). The ICC between the paper and mobile phone delivery of the SF-12 physical health composite score was 0.88 (95% CI, 0.79-0.93) and 0.86 (95% CI, 0.75-0.92) for the SF-12 mental health composite score. We find that text message delivery using mobile phones permits valid assessment of SF-12 and QuickDASH scores. The findings suggest that software-driven automated delivery of text communication to patients via mobile phones may be a valid method to obtain other PRO scores in orthopedic patients.

    Emerging adults use text messaging as a principal form of social communication, day and night, and this may compromise their sleep. In this study, a hypothetical model was tested linking daytime and nighttime text message use with multiple sleep characteristics. Subjective and objective measures of texting and sleep were utilized to assess 83 college students over a seven-day period during an academic term. Greater number of daily texts, awareness of nighttime cell phone notifications, and compulsion to check nighttime notifications were significantly associated with poorer subjective sleep quality. Awareness of nighttime notifications was significantly associated with higher self-reported global sleep problems and more sleep disruptions. Results suggest potential benefits of targeting nighttime texting habits in health promotion efforts for emerging adults.

    Mobile text messages are a widely recognized communication method in societies, as the global penetration of the technology approaches 100% worldwide. Systematic knowledge is still lacking on how the mobile telephone text messaging (short message service, SMS) has been used in health care services. This study aims to review the literature on the use of mobile phone text message reminders in health care. We conducted a systematic literature review of studies on mobile telephone text message reminders. The data sources used were PubMed (MEDLINE), CINAHL, Proquest Databases/ PsycINFO, EMBASE, Cochrane Library, Scopus, and hand searching since 2003. Studies reporting the use of SMS intended to remind patients in health services were included. Given the heterogeneity in the studies, descriptive characteristics, purpose of the study, response rates, description of the intervention, dose and timing, instruments, outcome measures, and outcome data from the studies were synthesized using a narrative approach. From 911 initial citations, 60 studies were included in the review. The studies reported a variety of use for SMS. Mobile telephone text message reminders were used as the only intervention in 73% (44/60) of the studies, and in 27% (16/60) of the remaining studies, SMS was connected to another comprehensive health intervention system. SMS reminders were sent to different patient groups: patients with HIV/AIDS (15%, 9/60) and diabetes (13%, 8/60) being the most common groups. The response rates of the studies varied from 22-100%. Typically, the text message reminders were sent daily. The time before the specific intervention to be rendered varied from 10 minutes (eg, medication taken) to 2 weeks (eg, scheduled appointment). A wide range of different evaluation methods and outcomes were used to assess the impact of SMS varying from existing databases (eg, attendance rate based on medical records), questionnaires, and physiological measures.

    To estimate whether women receiving daily text-message reminders have increased oral contraceptive pill adherence compared with women not receiving reminders. This randomized controlled trial estimated whether there was an effect of daily text-message reminders on oral contraceptive pill adherence of new oral contraceptive pill users. Pill-taking was tracked for 3 months by an electronic monitoring device with wireless data collection. During the study period, participants assigned the intervention received a daily reminder text message. Eighty-two women were assigned randomly to detect a 1.6+/-2.0 pill difference (90% power, 5% alpha, 15% dropout). Participants were 79% white, non-Hispanic, 99% high school graduates, and 99% nulliparous with a mean age of 22 years. Most reported condom use with past coital activity, and more than half reported prior emergency contraception use. The mean number of missed pills per cycle did not differ significantly between the groups: 4.9+/-3.0 for the text-message group and 4.6+/-3.5 for the control group (P=.60). The number of missed pills per cycle increased over the course of the study, but this pattern did not increase differentially between the groups. Adherence recorded by the electronic monitoring device indicated much poorer adherence than that recorded by patient diaries. Despite poor pill-taking, there were no pregnancies. Daily text-message reminders did not improve oral contraceptive pill adherence. Although the lack of benefit may be attributed to the frequent use of alternative reminder systems in the control group, the rate of missed pills when measured objectively was still very high in both groups.

    Existing evidence shows that text message interventions can produce short-term health behavior change. However, understanding is limited regarding intervention characteristics moderating this effect or the long-term effectiveness of text message interventions on behavior change after contact stops. MEDLINE, PubMed Central, ERIC, PsycINFO, and Web of Science were searched for articles published between April 2008 and December 2014 that evaluated an intervention targeting preventive health behaviors, delivered primarily by text message. Intervention development and design characteristics and research outcomes were evaluated for 51 studies. Thirty-five studies were included in a meta-analysis (conducted in 2015) examining overall effect size and moderators of effect size. The overall pooled effect of interventions was d=0.24 (95% CI=0.16, 0.32, pmaintenance period and showed a small but significant pooled maintenance effect (d=0.17, 95% CI=0.03, 0.31, p=0.017, k=7). Few variables significantly moderated intervention efficacy. Interventions that did not use a theoretic basis, used supplementary intervention components, and had a duration of 6-12 months were most effective. The specific behavior being targeted was not associated with differences in efficacy nor was tailoring, targeting, or personalization of text message content. Text message interventions are capable of producing positive change in preventive health behaviors. Preliminary evidence indicates that these effects can be maintained after the intervention stops. The moderator analysis findings are at odds with previous research, suggesting a need to examine moderators at the behavior-specific level. Copyright © 2017 American Journal of Preventive Medicine.

    To facilitate patient involvement in online health community and obtain informative support and emotional support they need, a topic identification approach was proposed in this paper for identifying automatically topics of the health-related messages in online health community, thus assisting patients in reaching the most relevant messages for their queries efficiently. Feature-based classification framework was presented for automatic topic identification in our study. We first collected the messages related to some predefined topics in a online health community. Then we combined three different types of features, n-gram-based features, domain-specific features and sentiment features to build four feature sets for health-related text representation. Finally, three different text classification techniques, C4.5, Naïve Bayes and SVM were adopted to evaluate our topic classification model. By comparing different feature sets and different classification techniques, we found that n-gram-based features, domain-specific features and sentiment features were all considered to be effective in distinguishing different types of health-related topics. In addition, feature reduction technique based on information gain was also effective to improve the topic classification performance. In terms of classification techniques, SVM outperformed C4.5 and Naïve Bayes significantly. The experimental results demonstrated that the proposed approach could identify the topics of online health-related messages efficiently.

    Postpartum depression (PPD) is the most common medical problem among new mothers that can have a negative impact on infant health. Traditional treatments are often difficult for low-income mothers to complete, particularly given the numerous barriers families face. Among low-income, primarily racial, and ethnic minority mothers with postpartum depression, our aim was to evaluate (1) the feasibility of sending supportive text messages, and (2) the perception of receiving private, supportive text messages for postpartum depression. Mothers found to be at risk for postpartum depression received supportive text messages four times weekly for 6 months in addition to receiving access to traditional counseling services based within an academic pediatric office. Feasibility was evaluated along with cellular and text messaging use, access, and perception of the message protocol. Perception of the message protocol was evaluated at study completion via a Likert scale questionnaire and open-ended qualitative survey. In total, 4158/4790 (86.81%) text messages were successfully delivered to 54 mothers over a 6-month period at a low cost (US $777.60). Among the 96 scripted messages, 37 unique messages (38.54%) allowed for a response. Of all sent messages that allowed for responses, 7.30% (118/1616) were responded to, and 66.1% of those responses requested a call back; 46% (25/54) of mothers responded at least once to a text message. Mothers felt that messages were easily received and read (25/28, 89%) and relevant to them personally (23/28, 82%). Most shared texts with others (21/28, 75%). Text messaging is feasible, well-accepted, and may serve as a simple, inexpensive adjunct therapy well-suited to cross socioeconomic boundaries and provide private support for at-risk mothers suffering from postpartum depression.

    Despite promising data in Western countries, there is a dearth of research into the efficacy of text messaging-based smoking cessation programs in other settings, including the Middle East, where smoking prevalence rates are higher. This paper reports cessation rates observed in SMS Turkey, a text messaging-based smoking cessation program for adult smokers in Ankara, Turkey. This study was a small-scale, parallel-group randomized controlled trial (RCT) conducted in Ankara, Turkey. Participants were adult daily smokers who were seriously thinking about quitting in the next 15 days and living in Ankara, Turkey. The text messaging intervention, SMS Turkey, provided 6 weeks of daily messages aimed at giving participants skills to help them quit smoking. Messages were sent in an automated fashion, except 2 days and 7 days after the initial quit day. On days 2 and 7, the research assistant manually assigned participants to content "paths" based on whether they were still not smoking or had relapsed. The control arm received a brochure that provided similar information about smoking cessation. The main outcome measure was self-reported 3-month sustained abstinence, verified by carbon monoxide (CO) readings. Neither participants nor researchers were blinded to arm assignment. The 151 participants were randomly assigned to 1 of 2 groups: 76 to the SMS Turkey intervention group and 75 to the brochure control group. Using intention to treat, all 151 participants were included in analyses. Three-month cessation trends were not significantly higher in the intervention group: 11% intervention vs 5% control had quit (χ(2)(1)=1.4, P=.24; R(2)=2.0, 95% CI 0.62-6.3). When the sample was stratified by sex, female intervention participants (14%, n=5) were significantly more likely to have quit at 3 months than female control participants (0%, n=0; χ(2)(1)=3.7, P=.05). Among light smokers (ie, those smoking less than 20 cigarettes per day), intervention participants (17%, n=5) also

    Although adolescent tobacco use has declined in the last 10 years, African American high school seniors' past 30-day use has increased by 12 %, and as they age they are more likely to report lifetime use of tobacco. Very few urban youth are enrolled in evidenced-based smoking prevention and cessation programming. Therefore, we tested a text messaging smoking cessation intervention designed to engage urban youth through an automated texting program utilizing motivational interviewing-based peer network counseling. We recruited 200 adolescents (90.5 % African American) into a randomized controlled trial that delivered either the experimental intervention of 30 personalized motivational interviewing-based peer network counseling messages, or the attention control intervention, consisting of text messages covering general (non-smoking related) health habits. All adolescents were provided smart phones for the study and were assessed at baseline, and at 1, 3, and 6 months post intervention. Utilizing repeated measures general linear models we examined the effects of the intervention while controlling for race, gender, age, presence of a smoker in the home, and mental health counseling. At 6 months, participants in the experimental condition significantly decreased the number of days they smoked cigarettes and the number of cigarettes they smoked per day; they significantly increased their intentions not to smoke in the future; and significantly increased peer social support among girls. For boys, participants in the experimental condition significantly reduced the number of close friends in their networks who smoke daily compared to those in the control condition. Effect sizes ranged from small to large. These results provide encouraging evidence of the efficacy of text messaging interventions to reduce smoking among adolescents and our intervention holds promise as a large-scale public health preventive intervention platform.

    Text4baby is the only free text-message program for pregnancy available. Our objective was to determine whether content differed between Text4baby and popular pregnancy smart phone applications (apps). Researchers enrolled in Text4baby in 2012 and downloaded the four most-popular free pregnancy smart phone apps in July 2013; content was re-extracted in February 2014. Messages were assigned thematic codes. Two researchers coded messages independently before reviewing all the codes jointly to ensure consistency. Logistic regression modeling determined statistical differences between Text4baby and smart phone apps. About 1399 messages were delivered. Of these, 333 messages had content related to more than one theme and were coded as such, resulting in 1820 codes analyzed. Compared to smart phone apps, Text4baby was significantly more likely to have content regarding Postpartum Planning, Seeking Care, Recruitment and Prevention and significantly less likely to mention Normal Pregnancy Symptoms. No messaging program included content regarding postpartum contraception. To improve content without increasing text message number, Text4baby could replace messages on recruitment with messages regarding normal pregnancy symptoms, fetal development and postpartum contraception.

    Extending contact with participants after the end of an initial weight loss intervention has been shown to lead to maintained weight loss and related behavioral change. Mobile phone text messaging (short message service, SMS) offers a low-cost and efficacious method to deliver extended contact. In this rapidly developing area, formative work is required to understand user perspectives of text message technology. An extended contact intervention delivered by text messages following an initial telephone-delivered weight loss intervention in breast cancer survivors provided this opportunity. The aim of this study was to qualitatively explore women's perceptions of participation in an extended contact intervention using text messaging to support long-term weight loss, physical activity, and dietary behavioral change. Following the end of an initial 6-month randomized controlled trial of a telephone-delivered weight loss intervention (versus usual care), participants received a 6-month extended contact intervention via tailored text messages. Participant perceptions of the different types of text messages, the content, tailoring, timing, and frequency of the text messages, and the length of the intervention were assessed through semistructured interviews conducted after the extended contact intervention. The interviews were transcribed verbatim and analyzed with key themes identified. Participants (n=27) were a mean age of 56.0 years (SD 7.8) and mean body mass index of 30.4 kg/m2 (SD 4.2) and were at a mean of 16.1 months (SD 3.1) postdiagnosis at study baseline. Participants perceived the text messages to be useful behavioral prompts and felt the messages kept them accountable to their behavioral change goals. The individual tailoring of the text message content and schedules was a key to the acceptability of the messages; however, some women preferred the support and real-time discussion via telephone calls (during the initial intervention) compared with the text

    There is no functional pharmacovigilance system in Cambodia to our knowledge. Mobile phone-based tools, such as short message service (SMS) text messages, are increasingly used for surveillance purposes. To pilot-test the FrontlineSMS mobile phone-based tool for notification of adverse events, using Cambodia's only International Vaccination Center at the Institut Pasteur du Cambodge as a field site. People receiving vaccinations, aged over 18 years, and who owned a cell phone were recruited in the study following informed consent. The names and mobile phone numbers of the participants interviewed were entered each day into the FrontlineSMS software. Two days after being vaccinated, participants received an automatically generated SMS text message asking whether any adverse events had occurred. Their SMS reply was number-coded and exported from the software daily to an Excel spreadsheet and examined before being saved. If the participant replied with a code for a severe adverse event (8 or 9), they were automatically advised to consult the nearest doctor. The active surveillance study was conducted over 72 days in the spring of 2012. Patients agreed to be asked by SMS text message whether unwanted events had occurred after vaccination. Of 1331 persons aged over 18 years referred to the vaccination unit, 184 (13.8%) were asked and agreed to participate. When texted for clinical status 48 hours after vaccination, 52 (28.3%) participants did not reply, 101 (54.9%) sent an immediate SMS reply, and 31 (16.8%) sent an SMS reply after additional prompting. Of the initial 184 participants, 132 (71.7%) replied. These 132 participants received 135 vaccine doses and 109 (82.6%) reported no adverse events, whereas 23 (17.4%) reported adverse events, all benign. Notification using an SMS-based text message system is already used in Cambodia for syndromic surveillance in health centers and reporting by health care workers. Our results show that such tools can also be useful for

    Background Mobile health interventions are often standardized and assumed to work the same for all users; however, we may be missing cultural differences in the experiences of interventions that may impact how and if an intervention is effective. Objective The objective of the study was to assess qualitative feedback from participants to determine if there were differences between Spanish speakers and English speakers. Daily text messages were sent to patients as an adjunct to group Cognitive Behavioral Therapy (CBT) for depression. Methods Messages inquired about mood and about specific themes (thoughts, activities, social interactions) of a manualized group CBT intervention. There were thirty-nine patients who participated in the text messaging pilot study. The average age of the participants was 53 years (SD 10.4; range of 23-72). Results Qualitative feedback from Spanish speakers highlighted feelings of social support, whereas English speakers noted increased introspection and self-awareness of their mood state. Conclusions These cultural differences should be explored further, as they may impact the effect of supportive mobile health interventions.

    Adolescents participating in weight loss programs experience difficulty adhering to behavior change recommendations. Communications technology provides a low cost means to increase the frequency of contact with adolescents which can improve their engagement and also lead to behavior change. Within a larger project on the development of tailored text messages for adolescents enrolled in an existing multidisciplinary weight management program, this study explored participants’ perspectives about message content. A library of messages was developed focused on topics central to weight management. Four focus groups were conducted with a total of 24 participants from the weight management program to gage their reactions to the messages. Detailed notes from the focus groups were analyzed to assess the acceptability of individual messages and to identify overriding themes. Results indicate that participants were very enthusiastic about receiving text messages. They preferred messages that provided recipe ideas, included successful weight loss strategies used by peers, and requested feedback regarding their progress. They preferred positive, encouraging, and direct messages. They were unanimous that messages should include encouraging symbols (e.g., exclamation points and “smiley faces”) as often as possible. They emphasized that any mention of unhealthy foods or behaviors would trigger them to eat those foods or engage in those behaviors. Text messaging acronyms (e.g., LOL) were considered too informal for messages from healthcare providers. This study suggests that including text messages in obesity interventions is acceptable to obese adolescents as a means of supporting their weight loss efforts, and it highlights the need for such messages to be carefully constructed.

    Adolescents participating in weight loss programs experience difficulty adhering to behavior change recommendations. Communications technology provides a low cost means to increase the frequency of contact with adolescents which can improve their engagement and also lead to behavior change. Within a larger project on the development of tailored text messages for adolescents enrolled in an existing multidisciplinary weight management program, this study explored participants' perspectives about message content. A library of messages was developed focused on topics central to weight management. Four focus groups were conducted with a total of 24 participants from the weight management program to gage their reactions to the messages. Detailed notes from the focus groups were analyzed to assess the acceptability of individual messages and to identify overriding themes. Results indicate that participants were very enthusiastic about receiving text messages. They preferred messages that provided recipe ideas, included successful weight loss strategies used by peers, and requested feedback regarding their progress. They preferred positive, encouraging, and direct messages. They were unanimous that messages should include encouraging symbols (e.g., exclamation points and "smiley faces") as often as possible. They emphasized that any mention of unhealthy foods or behaviors would trigger them to eat those foods or engage in those behaviors. Text messaging acronyms (e.g., LOL) were considered too informal for messages from healthcare providers.

    Full Text Available In interpreting verbal messages, humans use not only verbal information but also non-verbal signals such as facial expression. For example, when a person says yes with a troubled face, what he or she really means appears ambiguous. In the present study, we examined how deaf and hearing people differ in perceiving real meanings in texts accompanied by representations of facial expression. Deaf and hearing participants were asked to imagine that the face presented on the computer monitor was asked a question from another person (e.g., do you like her?. They observed either a realistic or a schematic face with a different magnitude of positive or negative expression on a computer monitor. A balloon that contained either a positive or negative text response to the question appeared at the same time as the face. Then, participants rated how much the individual on the monitor really meant it (i.e., perceived earnestness, using a 7-point scale. Results showed that the facial expression significantly modulated the perceived earnestness. The influence of positive expression on negative text responses was relatively weaker than that of negative expression on positive responses (i.e., no tended to mean no irrespective of facial expression for both participant groups. However, this asymmetrical effect was stronger in the hearing group. These results suggest that the contribution of facial expression in perceiving real meanings from text messages is qualitatively similar but quantitatively different between deaf and hearing people.

    This study examined the effects of electronic communication distractions, including cell-phone and texting demands, on true and false recognition, specifically semantically related words presented and not presented on a computer screen. Participants were presented with 24 Deese-Roediger-McDermott (DRM) lists while manipulating the concurrent presence or absence of cell-phone and text-message distractions during study. In the DRM paradigm, participants study lists of semantically related words (e.g., mother, crib, and diaper) linked to a non-presented critical lure (e.g., baby). After studying the lists of words, participants are then requested to recall or recognize previously presented words. Participants often not only demonstrate high remembrance for presented words (true memory: crib), but also recollection for non-presented words (false memory: baby). In the present study, true memory was highest when participants were not presented with any distraction tasks during study of DRM words, but poorer when they were required to complete a cell-phone conversation or text-message task during study. False recognition measures did not statistically vary across distraction conditions. Signal detection analyses showed that participants better discriminated true targets (list items presented during study) from true target controls (items presented during study only) when cell-phone or text-message distractions were absent than when they were present. Response bias did not vary significantly across distraction conditions, as there were no differences in the likelihood that a participant would claim an item as "old" (previously presented) rather than "new" (not previously presented). Results of this study are examined with respect to both activation monitoring and fuzzy trace theories.

    There has been little progress in adolescent health outcomes in recent decades. Researchers and youth-serving organizations struggle to accurately elicit youth voice and translate youth perspectives into health care policy. Our aim is to describe the protocol of the MyVoice Project, a longitudinal mixed methods study designed to engage youth, particularly those not typically included in research. Text messaging surveys are collected, analyzed, and disseminated in real time to leverage youth perspectives to impact policy. Youth aged 14 to 24 years are recruited to receive weekly text message surveys on a variety of policy and health topics. The research team, including academic researchers, methodologists, and youth, develop questions through an iterative writing and piloting process. Question topics are elicited from community organizations, researchers, and policy makers to inform salient policies. A youth-centered interactive platform has been developed that automatically sends confidential weekly surveys and incentives to participants. Parental consent is not required because the survey is of minimal risk to participants. Recruitment occurs online (eg, Facebook, Instagram, university health research website) and in person at community events. Weekly surveys collect both quantitative and qualitative data. Quantitative data are analyzed using descriptive statistics. Qualitative data are quickly analyzed using natural language processing and traditional qualitative methods. Mixed methods integration and analysis supports a more in-depth understanding of the research questions. We are currently recruiting and enrolling participants through in-person and online strategies. Question development, weekly data collection, data analysis, and dissemination are in progress. MyVoice quickly ascertains the thoughts and opinions of youth in real time using a widespread, readily available technology-text messaging. Results are disseminated to researchers, policy makers, and

  12. Three-Phase Text Error Correction Model for Korean SMS Messages

    Science.gov (United States)

    Byun, Jeunghyun; Park, So-Young; Lee, Seung-Wook; Rim, Hae-Chang

    In this paper, we propose a three-phase text error correction model consisting of a word spacing error correction phase, a syllable-based spelling error correction phase, and a word-based spelling error correction phase. In order to reduce the text error correction complexity, the proposed model corrects text errors step by step. With the aim of correcting word spacing errors, spelling errors, and mixed errors in SMS messages, the proposed model tries to separately manage the word spacing error correction phase and the spelling error correction phase. For the purpose of utilizing both the syllable-based approach covering various errors and the word-based approach correcting some specific errors accurately, the proposed model subdivides the spelling error correction phase into the syllable-based phase and the word-based phase. Experimental results show that the proposed model can improve the performance by solving the text error correction problem based on the divide-and-conquer strategy.

    This mixed-methods study applies Communication Accommodation Theory to explore how liking, power, and sex predict one's likelihood for using textisms in digital interpersonal interactions. Textisms are digital cues that convey nonverbal meaning and emotion in text communication. The main experiment used a hypothetical texting scenario to manipulate textism amounts (none/many) and participant's perceived power levels (low/equal/high) during texting interactions to examine the number of textisms participants used in subsequent responses in comparison to the number of textisms they viewed. Primary results show that (1) participants moderately converged to use similar amounts of textisms, and (2) those with low power who viewed many textisms were more likely to use textisms themselves during subsequent responses. Through the examination of adaption behaviors in text messaging, scholars can better understand the contexts in which users will include textisms to intentionally convey nonverbal meaning and emotion in digital communication.

    Growing evidence suggests that text messaging programs are effective in facilitating health behavior change. However, high dropout rates limit the potential effectiveness of these programs. This paper describes patterns of early dropout in the HealthyYou text (HYTxt) program, with a focus on the impact of baseline motivation quality on dropout, as characterized by Self-Determination Theory (SDT). This analysis included 193 users of HYTxt, a diet and physical activity text messaging intervention developed by the US National Cancer Institute. Descriptive statistics were computed, and logistic regression models were run to examine the association between baseline motivation type and early program dropout. Overall, 43.0% (83/193) of users dropped out of the program; of these, 65.1% (54/83; 28.0% of all users) did so within the first 2 weeks. Users with higher autonomous motivation had significantly lower odds of dropping out within the first 2 weeks. A one unit increase in autonomous motivation was associated with lower odds (odds ratio 0.44, 95% CI 0.24-0.81) of early dropout, which persisted after adjusting for level of controlled motivation. Applying SDT-based strategies to enhance autonomous motivation might reduce early dropout rates, which can improve program exposure and effectiveness.

    Virtual forms of communication (eg texting) can support patients and may contribute to better care. However, these informal communication methods may intrude on the doctor’s leisure time and undermine standards of care if they replace face-to-face consultations.Texting may cross boundaries in potentially unprofessional ways, especially when particular patients are favoured with this privilege. It may disadvantage patients who are not favoured or who are not comfortable using mobile technology. We also note that GPs cannot control the distribution of their number or recall it without the inconvenience of changing the number once it has been disclosed.Virtual communication is an integral part of the way we live, despite the potential pitfalls. Each form (social media, electronic messaging systems, video consultations, mobile phones, etc) has its advantages and disadvantages. This makes it important for practices to develop policies supporting the responsible use of virtual communication. Such policies should:clarify (for patients and GPs) when its use is appropriate accommodate doctors’ individual preferences regarding technology provide guidance regarding GPs’ duties, especially for interactions that do not allow full evaluation of patients.GPs may wish to have specific criteria for providing patients with this degree of access, set very clear indications and contraindications to its use, explain the potential pitfalls, and ensure that text messages augment good care rather than replace it.

    Coronary heart disease (CHD) is a leading cause of morbidity and mortality in India. Text message based prevention programs have demonstrated reduction in cardiovascular risk factors among patients with CHD in selected populations. Customisation is important as behaviour change is influenced by culture and linguistic context. To customise a mobile phone text message program supporting behaviour and treatment adherence in CHD for delivery in North India. We used an iterative process with mixed methods involving three phases: (1) Initial translation, (2) Review and incorporation of feedback including review by cardiologists in India to assess alignment with local guidelines and by consumers on perceived utility and clarity and (3) Pilot testing of message management software. Messages were translated in three ways: symmetrical translation, asymmetrical translation and substitution. Feedback from cardiologists and 25 patients was incorporated to develop the final bank. Patients reported Hinglish messages were easy to understand (93%) and useful (78%). The software located in Australia successfully delivered messages to participants based in Delhi-surrounds (India). Our process for customisation of a text message program considered cultural, linguistic and the medical context of potential participants. This is important in optimising intervention fidelity across populations enabling examination of the generalisability of text message programs across populations. We also demonstrated the customised program was acceptable to patients in India and that a centralised cross-country delivery model was feasible. This process could be used as a guide for other groups seeking to customise their programs. TEXTMEDS Australia (Parent study)-ACTRN 12613000793718.

    Mobile and automated technologies are increasingly becoming integrated into mental health care and assessment. The purpose of this study was to determine how automated daily mood ratings are related to the Patient Health Questionnaire-9 (PHQ-9), a standard measure in the screening and tracking of depressive symptoms. There was a significant relationship between daily mood scores and PHQ-9 scores, and between one-week average mood scores and PHQ-9 scores, controlling for linear change in depression scores. PHQ-9 scores were not related to the average of two week mood ratings. This study also constructed models using variance, maximum, and minimum values of mood ratings in the preceding week and two-week periods as predictors of PHQ-9. None of these variables significantly predicted PHQ-9 scores when controlling for daily mood ratings and the corresponding averages for each period. This study only assessed patients who were in treatment for depression, therefore findings might not generalize to the relationship between text message mood ratings for those who are not depressed. The sample was also predominantly Spanish speaking and low-income making generalizability to other populations uncertain. Our results show that automatic text message based mood ratings can be a clinically useful proxy for the PHQ-9. Importantly, this approach avoids the limitations of the PHQ-9 administration, which include length and a higher requirement for literacy. Copyright © 2015 Elsevier B.V. All rights reserved.

    Research has demonstrated that use of texting slang (textisms) when text messaging does not appear to impact negatively on children's literacy outcomes and may even benefit children's spelling attainment. However, less attention has been paid to the impact of text messaging on the development of children's and young people's understanding of grammar. This study therefore examined the interrelationships between children's and young adults' tendency to make grammatical violations when texting a...

    A fully immersive, high-fidelity street-crossing simulator was used to examine the effects of texting on pedestrian street-crossing performance. Research suggests that street-crossing performance is impaired when pedestrians engage in cell phone conversations. Less is known about the impact of texting on street-crossing performance. Thirty-two young adults completed three distraction conditions in a simulated street-crossing task: no distraction, phone conversation, and texting. A hands-free headset and a mounted tablet were used to conduct the phone and texting conversations, respectively. Participants moved through the virtual environment via a manual treadmill, allowing them to select crossing gaps and change their gait. During the phone conversation and texting conditions, participants had fewer successful crossings and took longer to initiate crossing. Furthermore, in the texting condition, smaller percentage of time with head orientation toward the tablet, fewer number of head orientations toward the tablet, and greater percentage of total characters typed before initiating crossing predicted greater crossing success. Our results suggest that (a) texting is as unsafe as phone conversations for street-crossing performance and (b) when subjects completed most of the texting task before initiating crossing, they were more likely to make it safely across the street. Sending and receiving text messages negatively impact a range of real-world behaviors. These results may inform personal and policy decisions. © 2015, Human Factors and Ergonomics Society.

    BACKGROUND SmokefreeVET is a text messaging smoking cessation program available to veterans enrolled in the Veterans Health Administration. SmokefreeVET was developed in collaboration with the National Cancer Institute as part of the SmokefreeTXT initiative. PURPOSE To evaluate the real world use of and effectiveness of the SmokefreeVET program for SmokefreeVET users who enrolled between 2013 and 2014. METHODS Demographics and smoking behavior of 1,470 SmokefreeVET users who enrolled between 2013 and 2014 were analyzed. Latent growth mixture modeling was used to identify discrete classes of SmokefreeVET users based on engagement patterns. Multi-level modeling determined class differences in abstinence. RESULTS The average age of the SmokefreeVET user was 48, 75% of users were male, and 84% were daily smokers. After five weeks, 13% of all users reported abstinence from smoking. Five statistically distinct engagement classes of SmokefreeVET users were identified. Highly engaged classes were significantly less likely to opt-out and more likely to report abstinence. Over 60% of users who were classified as high engagers throughout the program reported abstinence 5 weeks after their quit date. Users were more likely to report abstinence after two weeks if they used smoking cessation medication than those that did not use medication (OR=9.01, ptext messaging smoking cessation intervention.

    Full Text Available Abstract Background In 2010, there were approximately 8.8 million incident cases of tuberculosis (TB worldwide. The treatment of TB is at least six months long and may be complicated by a high pill burden. In addition, TB patients often do not take their medication on schedule simply because they forget. Mobile phone text messaging has the potential to help promote TB treatment adherence. We, therefore, propose to conduct a review of current best evidence for the use of mobile phone text messaging to promote patient adherence to TB treatment. Methods This is a systematic review of the literature. We will preferably include randomized controlled trials (RCTs. However, non-randomized studies (NRS will be considered if there is an inadequate number of RCTs. We will search PubMed, EMBASE, CINAHL, CENTRAL, Science Citation Index, Africa-Wide Information, and WHOLIS electronic databases for eligible studies available by 30 November 2012 regardless of language or publication status. We will also check reference lists for additional studies, identify abstracts from conference proceedings and communicate with authors for any relevant material. At least two authors will independently screen search outputs, select studies, extract data and assess the risk of bias (using separate criteria for RCTs and NRS; resolving discrepancies by discussion and consensus. We will assess clinical heterogeneity by examining the types of participants, interventions and outcomes in each study and pool studies judged to be clinically homogenous. We will also assess statistical heterogeneity using the chi-square test of homogeneity and quantify it using the I-square statistic. If study results are found to be statistically homogeneous (that is heterogeneity P > 0.1, we will pool them using the fixed-effect meta-analysis. Otherwise, we will use random-effects meta-analysis. We will calculate risk ratios and their corresponding 95% confidence intervals for dichotomous outcomes

  5. The impact of text message reminders on adherence to antimalarial treatment in northern Ghana: a randomized trial.

    Julia R G Raifman

    Full Text Available BACKGROUND: Low rates of adherence to artemisinin-based combination therapy (ACT regimens increase the risk of treatment failure and may lead to drug resistance, threatening the sustainability of current anti-malarial efforts. We assessed the impact of text message reminders on adherence to ACT regimens. METHODS: Health workers at hospitals, clinics, pharmacies, and other stationary ACT distributors in Tamale, Ghana provided flyers advertising free mobile health information to individuals receiving malaria treatment. The messaging system automatically randomized self-enrolled individuals to the control group or the treatment group with equal probability; those in the treatment group were further randomly assigned to receive a simple text message reminder or the simple reminder plus an additional statement about adherence in 12-hour intervals. The main outcome was self-reported adherence based on follow-up interviews occurring three days after treatment initiation. We estimated the impact of the messages on treatment completion using logistic regression. RESULTS: 1140 individuals enrolled in both the study and the text reminder system. Among individuals in the control group, 61.5% took the full course of treatment. The simple text message reminders increased the odds of adherence (adjusted OR 1.45, 95% CI [1.03 to 2.04], p-value 0.028. Receiving an additional message did not result in a significant change in adherence (adjusted OR 0.77, 95% CI [0.50 to 1.20], p-value 0.252. CONCLUSION: The results of this study suggest that a simple text message reminder can increase adherence to antimalarial treatment and that additional information included in messages does not have a significant impact on completion of ACT treatment. Further research is needed to develop the most effective text message content and frequency. TRIAL REGISTRATION: ClinicalTrials.gov NCT01722734.

    Tuberculosis (TB) remains a major global public health problem and mobile health (mHealth) interventions have been identified as a modality to improve TB outcomes. TextTB, an interactive text-based intervention to promote adherence with TB medication, was pilot-tested in Argentina with results supporting the implementation of trials at a larger scale. The objective of this research was to understand issues encountered during pilot-testing in order to inform future implementation in a larger-scale trial. A descriptive, observational qualitative design guided by a sociotechnical framework was used. The setting was a clinic within a public pulmonary-specialized hospital in Argentina. Data were collected through workflow observation over 115 days, text messages (n=2286), review of the study log, and stakeholder input. Emerging issues were categorized as organizational, human, technical, or sociotechnical considerations. Issues related to the intervention included workflow issues (eg, human, training, security), technical challenges (eg, data errors, platform shortcomings), and message delivery issues (eg, unintentional sending of multiple messages, auto-confirmation problems). System/contextual issues included variable mobile network coverage, electrical and Internet outages, and medication shortages. Intervention challenges were largely manageable during pilot-testing, but need to be addressed systematically before proceeding with a larger-scale trial. Potential solutions are outlined. Findings may help others considering implementing an mHealth intervention to anticipate and mitigate certain challenges. Although some of the issues may be context dependent, other issues such as electrical/Internet outages and limited resources are not unique issues to our setting. Release of new software versions did not result in solutions for certain issues, as specific features used were removed. Therefore, other software options will need to be considered before expanding into a

    Measuring self-reported substance use behavior is challenging due to issues related to memory recall and patterns of bias in estimating behavior. Limited research has focused on the use of ecological momentary assessment (EMA) to evaluate marijuana use. This study assessed the feasibility of using short message service (SMS) texting as a method of EMA with college-age marijuana users. Our goals were to evaluate overall response/compliance rates and trends of data missingness, response time, baseline measures (e.g., problematic use) associated with compliance rates and response times, and differences between EMA responses of marijuana use compared to timeline followback (TLFB) recall. Nine questions were texted to participants on their personal cell phones 3 times a day over a 2-week period. Overall response rate was high (89%). When examining predictors of the probability of data missingness with a hierarchical logistic regression model, we found evidence of a higher propensity for missingness for Week 2 of the study compared to Week 1. Self-regulated learning was significantly associated with an increase in mean response time. A model fit at the participant level to explore response time found that more time spent smoking marijuana related to higher response times, while more time spent studying and greater "in the moment" academic motivation and craving were associated with lower response times. Significant differences were found between the TLFB and EMA, with greater reports of marijuana use reported through EMA. Overall, results support the feasibility of using SMS text messaging as an EMA method for college-age marijuana users. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    Managing large student cohorts can be a challenge for university academics, coordinating these units. Bachelor of Nursing programmes have the added challenge of managing multiple groups of students and clinical facilitators whilst completing clinical placement. Clear, time efficient and effective communication between coordinating academics and clinical facilitators is needed to ensure consistency between student and teaching groups and prompt management of emerging issues. This study used a descriptive survey to explore the use of text messaging via a mobile phone, sent from coordinating academics to off-campus clinical facilitators, as an approach to providing direction and support. The response rate was 47.8% (n=22). Correlations were found between the approachability of the coordinating academic and clinical facilitator perception that, a) the coordinating academic understood issues on clinical placement (r=0.785, pacademics and clinical facilitators. Findings suggest improved connection, approachability and collaboration between the coordinating academic and clinical facilitation staff. Copyright © 2014 Elsevier Ltd. All rights reserved.

    More approaches to support weight control are needed, especially among racial minorities who shoulder a disproportionate obesity burden. Using an approach influenced by regulatory fit theory, we conducted a 28-day, 4-arm experimental trial with 89 obese adults recruited from urban, predominantly African American churches to ascertain the efficacy of framed text messages to motivate behaviors conducive to weight loss. Participants were assigned to receive message framing that was matched versus mismatched to their motivational orientation. Results were mixed overall; however, matched texts elicited greater motivation to change eating and exercise behavior, suggesting promise in using motivational approaches to tailor messages.

    SmokefreeVET is a text messaging smoking cessation program available to veterans enrolled in the Veterans Health Administration. SmokefreeVET was developed in collaboration with the National Cancer Institute as part of the SmokefreeTXT initiative. To evaluate the real world use of and effectiveness of the SmokefreeVET program for SmokefreeVET users who enrolled between 2013 and 2014. Demographics and smoking behavior of 1470 SmokefreeVET users who enrolled between 2013 and 2014 were analyzed. Latent growth mixture modeling was used to identify discrete classes of SmokefreeVET users based on engagement patterns. Multi-level modeling determined class differences in abstinence. The average age of the SmokefreeVET user was 48, 75% of users were male, and 84% were daily smokers. After five weeks, 13% of all users reported abstinence from smoking. Five statistically distinct engagement classes of SmokefreeVET users were identified. Highly engaged classes were significantly less likely to opt-out and more likely to report abstinence. Over 60% of users who were classified as high engagers throughout the program reported abstinence 5weeks after their quit date. Users were more likely to report abstinence after two weeks if they used smoking cessation medication than those that did not use medication (OR=9.01, pusers. Smoking cessation medication use was also associated with abstinence in SmokefreeVET users. Engagement appears to be a critical component when assessing the efficacy of a text messaging smoking cessation intervention. Published by Elsevier Ltd.

    Neighborhood features such as the density of tobacco outlets relative to one's home and evaluations of safety of one's activity space (routine locations), are known to influence health behaviors. Understanding the time-varying nature of these aspects of the urban ecology provides unique insights into the dynamic interactions of individuals and their environments. The present study tested the time-varying effects of tobacco outlets and perceived safety within a randomized controlled trial of an adolescent text-messaging smoking intervention. We used ecological momentary assessment data (EMA) from an automated text-messaging smoking cessation randomized trial with 197 primarily African American urban adolescents. We employed a time-varying effect model to estimate the effects of density of tobacco outlets within one-half mile of participants' home locations (time-invariant covariate) and evaluations of safety of their activity space (time-varying covariate) on momentary smoking over 6 months by treatment condition. The time-varying effect model approach models behavioral change and associations of coefficients expressed dynamically and graphically represented as smooth functions of time. Differences in trajectories of smoking between treatment conditions were apparent over the course of the study. During months 2 and 6, the association between tobacco outlet density and smoking was significantly stronger in the control condition, suggesting treatment dampens this association during these time periods. The intervention also significantly reduced the association of perceived safety and smoking among the treatment condition during months 3 through 6. Results support testing the time-varying effects of urban ecological features and perceptions of safety among adolescents in text-based smoking cessation interventions. This study makes a unique contribution towards understanding the time-varying effects of urban neighborhoods on adolescent tobacco use within the context of

    To assess the injury incidence in elite handball, and if gender and previous injuries are risk factors for new injuries. Cohort study of 517 male and female elite handball players (age groups under (u)16, u-18 and senior). Participants completed a web survey establishing injury history, demographic information and sports experience, and provided weekly reports of time-loss injuries and handball exposure for 31 weeks by short message service text messaging (SMS). Injuries were further classified by telephone interview. The weekly response rate ranged from 85% to 90% illustrating the promise of the SMS system as a tool in injury surveillance. Of 448 reported injuries, 165 injuries (37%) were overuse injuries and 283 (63%) traumatic injuries. Knee (19%) and ankle (29%) were the most common traumatic injuries. The injury incidence during match play was 23.5 (95% CI 17.8 to 30.4), 15.1 (95% CI 9.7 to 22.2), 11.1 (95% CI 7.0 to 16.6) injuries per 1000 match hours among senior, u-18 and u-16 players, respectively. U-18 male players had an overall 1.76 (95% CI 1.10 to 2.80) times higher risk of injury compared to females. Having had two or more previous injuries causing absence from handball for more than 4 weeks increased the risk of new injury in the u-16 group (IRR: 1.79 (95% CI 1.03 to 3.11)-2.23 (95% CI 1.22 to 4.10)). The incidence of time-loss injuries in elite handball was higher during match play than previously reported in recreational handball. Previous injuries were a risk factor for new injuries among u-16 players. Male players had a significant higher injury rate in the u-18 group.

    The use of new technologies, such as mobile phones and internet, has increased dramatically in recent years. Text messages offer a novel method of sexual health promotion to young people who are the greatest users of new technology and are also at high risk of sexually transmitted infections (STIs). In January 2008, young people aged between 16 and 29 years were recruited from a music festival in Melbourne, Australia. They completed a short survey and were asked to provide their mobile phone numbers. Participants received fortnightly short messaging service (SMS) relating to sexual health for 4 months, and then completed an online follow-up survey. Survey data were weighted to account for those lost to follow-up. McNemar's test was used to compare changes in survey responses. A total of 1771 participants were included in analysis as they were sexually active and provided a valid mobile phone number at baseline. In all, 18% (319/1771) withdrew from receiving the SMS during the broadcast period and 40% (587/1452) completed the follow-up survey. The majority reported on the follow-up survey that they found the SMS entertaining (80%), informative (68%), and they showed the SMS to others (73%). Weighted analyses found a significant increase in knowledge (P < 0.01) and STI testing (P < 0.05) over time in both males and females. The findings indicate that SMS appear to be a feasible, popular, and effective method of sexual health promotion to young people with a relatively low withdrawal rate, positive feedback, and an observed improvement in sexual health knowledge and STI testing.

    Parents can struggle while providing perioperative tonsillectomy care for their children at home. Short message service (SMS) technology is an accessible and direct modality to communicate timely, evidence-based recommendations to parents across the perioperative period. This study focused on validating a SMS protocol, Tonsil-Text-To-Me (TTTM), for parents of children undergoing tonsillectomy. This study used a modified Delphi expert consensus method. Participants were an international sample of 27 clinicians/researchers. Participants rated level of agreement with recommendations across seven perioperative domains, derived systematically from scientific and lay literature. A priori consensus analysis was conducted using threshold criterion. A multidisciplinary team of local clinicians were also individually interviewed to consolidate text messages and implement recurrent suggestions. In the modified Delphi panel, 30 statements reached threshold agreement (>3.0 of 4.0); recommendations surrounding diet (3.87) and hygiene (3.83) had the highest level of consensus, while recommendations regarding activity (3.42) and non-pharmacologic pain management (3.55) had the lowest consensus. The 30 statements reconfigured into 12 concise text messages. After further interviews with local clinicians, 14 final text messages were included in the SMS protocol to be sent two weeks preoperatively to one week postoperatively. This study illustrates the development of TTTM which is designed to deliver key sequential text messages at the optimal time during the perioperative setting to parents caring for their children who are undergoing tonsillectomy.

    Full Text Available Severin Haug Swiss Research Institute for Public Health and Addiction at Zurich University, Zurich, Switzerland Background: Alcohol and tobacco use are major causes of the disease burden in most countries of the world. Mobile phone text messaging is very popular among adolescents and young adults and has the potential to deliver individualized information to large population groups at low costs. Objective: To provide a narrative review on studies testing the appropriateness and effectiveness of text messaging-based programs to reduce alcohol and tobacco use in young people. Results: Two published studies on text message-based programs for the reduction of problem drinking and two studies on programs for enhancing smoking cessation were identified. A US-American pilot experimental study tested the feasibility and initial efficacy of a text messaging-based assessment and brief intervention among young adults identified during their emergency department visit with hazardous drinking. It demonstrated the feasibility of the text messaging-based program to collect drinking data in young adults after emergency department discharge. A Swiss pre–post study tested the appropriateness and initial effectiveness of a combined, individually tailored web- and text messaging (SMS-based program to reduce problem drinking in vocational school students. It provided evidence for the appropriateness of the intervention and initial evidence for its efficacy to reduce problem drinking. One of the two studies addressing smoking cessation was a US-American pilot randomized controlled trial. Participants were recruited via online advertisements and received text messages tailored according to their quitting stage. The intervention significantly affected self-reported quitting rates at 4 weeks but not at 3 months after the quit date. Within a cluster-randomized controlled trial conducted in Switzerland, smoking students were proactively recruited within vocational

    Type 2 diabetes mellitus (T2DM) is a disease affecting approximately 29.1 million people in the United States, and an additional 86 million adults have prediabetes. Diabetes self-management education, a complex health intervention composed of 7 behaviors, is effective at improving self-care behaviors and glycemic control. Studies have employed text messages for education, reminders, and motivational messaging that can serve as "cues to action," aiming to improve glucose monitoring, self-care behaviors, appointment attendance, and medication adherence. The Text to Move (TTM) study was a 6-month 2-parallel group randomized controlled trial of individuals with T2DM to increase physical activity, measured by a pedometer. The intervention arm received text messages twice daily for 6 months that were tailored to the participant's stage of behavior change as defined by the transtheoretical model of behavior change. We assessed participants' attitudes regarding their experience with text messaging, focusing on perceived barriers and facilitators, through two focus groups and telephone interviews. All interviews were audiorecorded, transcribed verbatim, coded, and analyzed using a grounded theory approach. The response rate was 67% (31/46 participants). The average age was 51.4 years and 61% (19/31 participants) were male. The majority of individuals were English speakers and married, had completed at least 12th grade and approximately half of the participants were employed full-time. Overall, participants were satisfied with the TTM program and recalled the text messages as educational, informational, and motivational. Program involvement increased the sense of connection with their health care center. The wearing of pedometers and daily step count information served as motivational reminders and created a sense of accountability through the sentinel effect. However, there was frustration concerning the automation of the text message program, including the repetitiveness

    Background Coronary heart disease (CHD) is a leading cause of morbidity and mortality in India. Text message based prevention programs have demonstrated reduction in cardiovascular risk factors among patients with CHD in selected populations. Customisation is important as behaviour change is influenced by culture and linguistic context. Objectives To customise a mobile phone text message program supporting behaviour and treatment adherence in CHD for delivery in North India. Methods We used an iterative process with mixed methods involving three phases: (1) Initial translation, (2) Review and incorporation of feedback including review by cardiologists in India to assess alignment with local guidelines and by consumers on perceived utility and clarity and (3) Pilot testing of message management software. Results Messages were translated in three ways: symmetrical translation, asymmetrical translation and substitution. Feedback from cardiologists and 25 patients was incorporated to develop the final bank. Patients reported Hinglish messages were easy to understand (93%) and useful (78%). The software located in Australia successfully delivered messages to participants based in Delhi-surrounds (India). Conclusions Our process for customisation of a text message program considered cultural, linguistic and the medical context of potential participants. This is important in optimising intervention fidelity across populations enabling examination of the generalisability of text message programs across populations. We also demonstrated the customised program was acceptable to patients in India and that a centralised cross-country delivery model was feasible. This process could be used as a guide for other groups seeking to customise their programs. Trial registration number TEXTMEDS Australia (Parent study)—ACTRN 12613000793718. PMID:27752288

    Background In solid organ transplant patients, non-participation in all aspects of the medical regimen is a prevalent problem associated with adverse consequences particularly in the adolescent and young adult (AYA) age group. This study is the first to evaluate the feasibility, utility and impact of a text messaging (TM) intervention to improve participation in laboratory testing in adolescent liver transplant patients. Methods AYA patients, aged 12 to 21 years, were recruited for a prospective pilot trial evaluating a TM intervention delivered over a 1-year period. The intervention involved automated TM reminders with feedback administered according to a prescribed laboratory testing frequency. Participation rate in laboratory testing after the intervention was compared to the year prior. Patient responses and feedback by text and survey were used to assess feasibility, acceptability and use of the intervention. Results Forty-two patients were recruited and 33 patients remained enrolled for the study duration. Recipients of the TM intervention demonstrated a significant improvement in participation rate in laboratory testing from 58% to 78% (P<.001). This rate was also significantly higher than in non-intervention controls (P=.003). There was a high acceptability, response rate and a significant correlation with reported versus actual completion of laboratory tests by TM. Conclusions TM reminders significantly improved participation in laboratory testing in AYA liver transplant patients. The intervention demonstrated feasibility, acceptability, and use with a high proportion of patients who engaged in and perceived a benefit from using this technology. PMID:26213633

    Full Text Available By looking at young Norwegians’ text messages in sexual romantic negotiations, this article examines whether text messages may provide a site for performing femininity and masculinity in ways that subvert traditional conceptions of these constructs. Although various studies on gender, sexuality and media [1] have consistently indicated gender specific usage/performances which in this article is indicated and supported by the study’s young informants’ own formulations, the discourse analysis approach employed a more complex image. Here, I focus on how the young people indicate and translate their modes and body-language into texts, paying particular attention to how signs of femininity and masculinity emerge in text message love-projects, I argue that especially for young males, text messages in love-projects offer a site where in particular young males may perform masculinity in counter-traditional ways. The article is a part of a long study of young Norwegian’s usages, self-understanding and gender performances through text message communication.

    Full Text Available Cell phones are the most ubiquitous communication device owned by young people today, and students’ text messaging during class is a common occurrence in many university classrooms. Analyzing data from a qualitative study involving 34 undergraduate students at a university in the Northeastern United States, this paper seeks to explore: Why do university students text message during class, and what does this tell us about text messaging as a new literacy practice within traditional classroom settings? Drawing on perspectives from new literacies and communication studies, I argue that texting was a meaningful practice for students as it afforded the opportunity for ongoing participation in social networks, and provided a means of exercising power within the controlled space of the classroom.

    Despite the widespread availability and convenience of short messaging systems, there has been limited adoption of this technology into the medical setting. Resistance may be attributable, in part, to the perceived lack of clinical benefit, privacy concerns, and a lack of physician compensation. This study evaluates the impact of a short messaging system clinical protocol between surgeons and patients. The endpoints evaluated were number of clinic visits, telephone calls, and days to surgical drain removal. Retrospective review identified 102 procedure-matched patients who underwent breast reconstruction for an oncologic diagnosis. A short messaging system protocol was routinely used by one of the two study surgeons. Data collected included demographics, pathologic findings, procedures, complications, clinic visits, clinic telephone calls, days until drain removal, and episode of drain removal. The two groups were well-matched for age, procedure, race, complications, and pathologic findings. Patients in the short messaging system clinical protocol had statistically fewer clinic visits within the first 30 days (p = 0.0004) and 90 days (p = 0.017) postoperatively. There were fewer clinic telephone calls in the messaging group (p = 0.0002). The short messaging system protocol allowed for fewer days until drain removal (9.67 ± 0 .41 versus 12.45 ± 1.02, p = 0.013). Patients in the messaging group were more likely to undergo drain removal at the first clinic visit. Benefits of a short messaging system protocol included reduced number of clinic visits, fewer overall days of drain requirement, and increased efficiency of clinic visits. Concerns regarding physician privacy, compensation, and time need to be addressed before further application of this technology. Therapeutic, III.

    Text messaging (TMs) on cell phones is emerging as an effective means of delivering behavioral interventions. However, little is known about TM use in adult cancer patients. The present study aimed to extend knowledge on acceptability of a TM intervention in adult cancer patients; examine factors of those screened and enrolled; and compare recruitment at a large national specialty pharmacy versus community-based cancer clinics. Screening, enrollment, and baseline data collected in two randomized controlled trials examining the efficacy of TMs on medication adherence or symptom severity in adults prescribed oral anticancer agents were linked. Chi-square, Fisher's exact, t-tests, and generalized linear modeling were used to examine sociodemographics, cancer type and stage, depressive symptoms, self-efficacy, social support, and symptoms. The cancer clinics screened 293 patients, 43% were eligible, and 56% consented. The specialty pharmacy screened 169 patients, 72% were eligible, and 74% consented. Mean age was 58 years and did not differ by recruitment setting. Later stage disease (p = 0.01) and higher number of symptoms (p cancer patients were likely to participate in a TM intervention trial. Recruiting through the specialty pharmacy reached a population with higher cell phone ownership and TM usage; with greater interest in a TM intervention compared to the cancer clinics.

    To consider whether Youth All Engaged! (a text message intervention) intensified the effects of the adolescent pregnancy prevention Teen Outreach Program (control) for youths. In this trial performed in Denver, Colorado, from 2011 to 2014, we randomized 8 Boys & Girls Clubs each of 4 years into 32 clubs per year combinations to ensure each club would serve as a treatment site for 2 years and a control site for 2 years. Control intervention consisted of the Teen Outreach Program only. We enrolled 852 youths (aged 14-18 years), and 632 were retained at follow-up, with analytic samples ranging from 50 to 624 across outcomes. We examined program costs, and whether the intervention increased condom and contraceptive use, access to care, and pregnancy prevention. Control program costs were $1184 per participant, and intervention costs were an additional $126 per participant (+10.6%). There were no statistically significant differences in primary outcomes for the full sample. Hispanic participants in the intervention condition had fewer pregnancies at follow-up (1.79%) than did those in the control group (6.72%; P = .02). Youth All Engaged is feasible, low cost, and could have potential benefits for Hispanic youths.

    High relapse rates in Major Depressive Disorder (MDD) indicate the need for interventions enhancing the sustainability of treatment outcomes. Primary aim of the present study was to evaluate the effectiveness of a text-message-based maintenance intervention for depression (TMMI-D). Additionally, we aimed to clarify whether the use of individualized messages would lead to better outcome than the use of standardized messages which focused upon adaptive ways of regulating undesired emotions. In this RCT, 226 individuals who had completed inpatient treatment for MDD were randomly allocated to a condition in which participants received TMMI-D with standardized messages targeting emotion regulation, or to a condition with individualized messages, or to a waitlist control condition. Primary outcome was depressive symptom severity assessed with the BDI-II. Multilevel analyses suggest that participants receiving TIMMI-D with standardized messages reported a significantly smaller increase of depressive symptoms during the post-treatment and follow-up interval than did patients in the waitlist control condition. Contrastingly, there was no such effect for patients who had used TIMMI-D with individualized messages. Limitations include proportions of missing data, thus, generalizing the findings of the present study might be an overestimation. Text-message-based interventions may help increase the sustainability of outcome after treatment for MDD. The unexpected superiority of the standardized over the individualized version is in line with research that points to the efficacy of interventions fostering adaptive emotion regulation as a means to treat depression (and other mental disorders).

    This research examined adolescents' written text messages with sexual content to investigate how sexting relates to sexual activity and borderline personality features. Participants (N = 181, 85 girls) completed a measure of borderline personality features prior to 10th grade and were subsequently given smartphones configured to capture the content of their text messages. Four days of text messaging were micro-coded for content related to sex. Following 12th grade, participants reported on their sexual activity and again completed a measure of borderline personality features. Results showed that engaging in sexting at age 16 was associated with reporting an early sexual debut, having sexual intercourse experience, having multiple sex partners, and engaging in drug use in combination with sexual activity two years later. Girls engaging in sex talk were more likely to have had sexual intercourse by age 18. Text messaging about hypothetical sex in grade 10 also predicted borderline personality features at age 18. These findings suggest that sending text messages with sexual content poses risks for adolescents. Programs to prevent risky sexual activity and to promote psychological health could be enhanced by teaching adolescents to use digital communication responsibly.

    Mobile health interventions have the potential to promote risk factor management and lifestyle modification, and are a particularly attractive approach for scaling across healthcare systems with limited resources. We are conducting two randomised trials to evaluate the efficacy of text message-based health messages in improving secondary coronary heart disease (CHD) prevention among patients with or without diabetes. The Cardiovascular Health And Text Messaging (CHAT) Study and the CHAT-Diabetes Mellitus (CHAT-DM) Study are multicentre, single-blind, randomised controlled trials of text messaging versus standard treatment with 6 months of follow-up conducted in 37 hospitals throughout 17 provinces in China. The intervention group receives six text messages per week which target blood pressure control, medication adherence, physical activity, smoking cessation (when appropriate), glucose monitoring and lifestyle recommendations including diet (in CHAT-DM). The text messages were developed based on behavioural change techniques, using models such as the information-motivation-behavioural skills model, goal setting and provision of social support. A total sample size of 800 patients would be adequate for CHAT Study and sample size of 500 patients would be adequate for the CHAT-DM Study. In CHAT, the primary outcome is the change in systolic blood pressure (SBP) at 6 months. Secondary outcomes include a change in proportion of patients achieving a SBP CHAT-DM, the primary outcome is the change in glycaemic haemoglobin (HbA 1C ) at 6 months.

    Cell phone text messaging, via the Short Messaging Service (SMS), offers the promise of a highly portable, well-accepted, and inexpensive modality for engaging youth and young adults in the management of their diabetes. This pilot and feasibility study compared two-way SMS cell phone messaging with e-mail reminders that were directed at encouraging blood glucose (BG) monitoring. Forty insulin-treated adolescents and young adults with diabetes were randomized to receive electronic reminders to check their BG levels via cell phone text messaging or e-mail reminders for a 3-month pilot study. Electronic messages were automatically generated, and participant replies with BG results were processed by the locally developed Computerized Automated Reminder Diabetes System (CARDS). Participants set their schedule for reminders on the secure CARDS website where they could also enter and review BG data. Of the 40 participants, 22 were randomized to receive cell phone text message reminders and 18 to receive e-mail reminders; 18 in the cell phone group and 11 in the e-mail group used the system. Compared to the e-mail group, users in the cell phone group received more reminders (180.4 vs. 106.6 per user) and responded with BG results significantly more often (30.0 vs. 6.9 per user, P = 0.04). During the first month cell phone users submitted twice as many BGs as e-mail users (27.2 vs. 13.8 per user); by month 3, usage waned. Cell phone text messaging to promote BG monitoring is a viable and acceptable option in adolescents and young adults with diabetes. However, maintaining interest levels for prolonged intervals remains a challenge.

    This multisite, randomized controlled trial assigned 75 adult cancer patients prescribed an oral anticancer agent to either an experimental group that received daily text messages for adherence for 21 days plus usual care or a control group that received usual care. Measures were administered at baseline, weekly (Weeks 1-8), and at exit (Week 9). A satisfaction survey was conducted following the intervention. Acceptability, feasibility, and satisfaction were examined. Primary outcomes were adherence and symptoms. Secondary outcomes were depressive symptoms, self-efficacy, cognition, physical function, and social support. Mixed or general linear models were used for the analyses comparing trial groups. Effect sizes (ES) were estimated to gauge clinical significance. Regarding acceptability, 57.2% (83 of 145) of eligible patients consented, 88% (n = 37 of 42) receiving text messages read them most or all of the time, and 90% (n = 38) were satisfied. The differences between experimental and control groups' ES were 0.29 for adherence, 0.21 for symptom severity, and 0.21 for symptom interference, and differences were not statistically significant. Furthermore, perceived social support was higher (p = 0.04; ES = 0.54) in the experimental group. Proof of concept and preliminary efficacy of a mobile health intervention using text messages to promote adherence for patients prescribed oral anticancer agents were demonstrated. Patients accepted and had high satisfaction with the intervention, and adherence improved after the intervention. Text messages show promise. Additional research is needed prior to use in practice.

    Using text messaging for vaccine safety monitoring, particularly for non-medically attended events, would be valuable for pandemic influenza and emergency vaccination program preparedness. We assessed the feasibility and acceptability of text messaging to evaluate fever and wheezing post-influenza vaccination in a prospective, observational, multi-site pediatric study. Children aged 2-11 years old, with an emphasis on children with asthma, were recruited during the 2014-2015 influenza season from three community-based clinics in New York City, and during the 2014-2015 and 2015-2016 seasons from a private practice in Fall River, Massachusetts. Parents of enrolled children receiving quadrivalent live attenuated (LAIV4) or inactivated influenza vaccine (IIV4) replied to text messages assessing respiratory symptoms (day 3 and 7, then weekly through day 42), and temperature on the night of vaccination and the next seven nights (day 0-7). Missing data were collected via diary (day 0-7 only) and phone. Phone confirmation was obtained for both presence and absence of respiratory symptoms. Reporting rates, fever (T≥100.4 °F) frequency, proportion of wheezing and/or chest tightness reports captured via text message versus all sources (text, phone, diary, electronic health record) and parental satisfaction were assessed. Across both seasons, 266 children were analyzed; 49.2% with asthma. Parental text message response rates were high (>70%) across sites. Overall, fever frequency was low (day 0-2: 4.1% [95% confidence interval (CI) 2.3-7.4%]; d3-7: 6.7% [95% CI 4.1-10.8%]). A third (39.2%) of parents reported a respiratory problem in their child, primarily cough. Most (88.2%) of the 52 wheezing and/or chest tightness reports were by text message. Most (88.1%) participants preferred text messaging over paper reporting. Text messaging can provide information about pediatric post-vaccination fever and wheezing and was viewed positively by parents. It could be a helpful tool

    To determine how receptive patients are to the use of e-mail and text message reminders for appointments and medications. We conducted a consecutive cross-sectional survey of eligible patients with glaucoma or ocular hypertension at a private glaucoma subspecialty practice with 3 locations from February 2011 to January 2012. Main outcome measures were answers to survey questions regarding how receptive patients are to e-mail and text messaging reminders for appointments and medications. Of 989 patients, 404 (40.8%) patients reported that e-mail reminders would help remember appointments and 185 (18.7%) reported that they would help for medications. Among those with access to text messaging, 280 (68.9%) reported text messaging would help them remember appointments and 193 (47.5%) reported it would help with medications. Patients who reported e-mail would help them remember medications were more likely to live in an urban location [P=0.05, odds ratio (OR)=1.84], check the internet at least daily (P≤0.001, OR=1.04), check e-mail when not at home or the office (P=0.02, OR=1.62), and know how to open attachments (P=0.03, OR=1.87). Patients who reported that text messaging would help them remember their medications were more likely to be 40 or less (P≤0.001, OR=8.54) and African American (PE-mail and text messaging reminders currently may have a limited utility in improving adherence in the general glaucoma population but may be useful in younger patients with glaucoma.

    Medication adherence is a complex behavior that is influenced by numerous factors. Applying self-efficacy theory, the primary aim of this randomized controlled trial was to compare medication self-efficacy among patients with coronary heart disease who received: (a) text messages (TMs) for medication reminders and education, (b) TMs for education, or (c) no TMs. The second aim was to identify the personal (sociodemographic and clinical characteristics) and psychosocial factors that were associated with and predicted medication adherence. Customized TMs were delivered over 30 days. Repeated measures analysis of variance was used to analyze medication self-efficacy. A multiple regression analysis was performed at baseline and follow-up to determine variables that were associated with and predicted self-reported medication adherence. Among 90 subjects with mean age 59.2 years (standard deviation (SD) 9.4, range 35-83), total scores for medication self-efficacy improved over 30 days; however, there was no significant difference in this improvement as a function of the different treatment groups (p=0.64). Controlling for other variables in the model (age, education, depression, and social support), less depression (p=0.004) and higher social support (p=0.02) positively predicted higher medication adherence in the final model. TM medication reminders and/or health education did not improve medication self-efficacy. Further theory testing of current and future models and interventions are required to understand variables related to self-efficacy and medication adherence. Addressing psychosocial factors such as depression and social support should be a priority to improve medication adherence among patients with coronary heart disease. © The European Society of Cardiology 2014.

  16. Using text messages to bridge the intention-behavior gap? A pilot study on the use of text message reminders to increase objectively assessed physical activity in daily life

    Full Text Available Sedentarism is a serious health concern in industrialized countries throughout the world. We examined whether a text message-based intervention, targeted at increasing daily levels of physical activity, would be more effective than a standard psychoeducational intervention and a control condition. Sixty-three individuals (43 women with a mean age of 23.7 years participated in the study. They were randomly assigned to a psychoeducational standard intervention; an augmented intervention with additional short text messages sent to the mobile phones to remind participants of their action plans, and a control condition. Objectively assessed physical activity and self-efficacy were assessed pre- and post-intervention. Participants in the control condition showed a significant decline in physical activity from pre- assessment to post-assessment, whereas participants in both intervention arms exhibited a slight increase. Moreover, the augmented intervention resulted in a marginally significant increase in self-efficacy, whereas the standard intervention resulted in a significant decrease. The findings suggest that short text messages reminding individuals of their action plans are not more effective than an intervention without text messages, although there seems to be a beneficial effect on self-efficacy, which might facilitate behavior change in the long-term. Challenging aspects of the research design (e.g., reactivity of the assessment protocol are discussed and suggestions for future research are highlighted.

    Some adults with Type 2 diabetes mellitus have difficulty adhering to their oral medication regimens. The current study used a multiple baseline design with 3 adults with Type 2 diabetes. Medication taking was monitored remotely in real time via an electronic pill bottle. During the intervention, monetary incentives were delivered contingent on evidence of adherence to taking medication at specified times. Text-message reminders were also sent if medication was not taken. Adherence increased for all participants. Future studies should separate the relative contributions of text-message and incentive components of the intervention. © 2016 Society for the Experimental Analysis of Behavior.

    2014-11-01

    Research has demonstrated that use of texting slang (textisms) when text messaging does not appear to impact negatively on children's literacy outcomes and may even benefit children's spelling attainment. However, less attention has been paid to the impact of text messaging on the development of children's and young people's understanding of grammar. This study therefore examined the interrelationships between children's and young adults' tendency to make grammatical violations when texting and their performance on formal assessments of spoken and written grammatical understanding, orthographic processing and spelling ability over the course of 1 year. Zero-order correlations showed patterns consistent with previous research on textism use and spelling, and there was no evidence of any negative associations between the development of the children's performance on the grammar tasks and their use of grammatical violations when texting. Adults' tendency to use ungrammatical word forms ('does you') was positively related to performance on the test of written grammar. Grammatical violations were found to be positively associated with growth in spelling for secondary school children. However, not all forms of violation were observed to be consistently used in samples of text messages taken 12 months apart or were characteristic of typical text messages. The need to differentiate between genuine errors and deliberate violation of rules is discussed, as are the educational implications of these findings. © 2014 The Authors.

    Full Text Available Objective. To assess a text messaging intervention to promote tuberculosis (TB treatment adherence. Methods. A mixed-methods pilot study was conducted within a public pulmonary-specialized hospital in Argentina. Patients newly diagnosed with TB who were 18 or older, and had mobile phone access were recruited and randomized to usual care plus either medication calendar (n=19 or text messaging intervention (n=18 for the first two months of treatment. Primary outcomes were feasibility and acceptability; secondary outcomes explored initial efficacy. Results. Feasibility was evidenced by high access to mobile phones, familiarity with texting, most phones limited to basic features, a low rate of participant refusal, and many describing suboptimal TB understanding. Acceptability was evidenced by participants indicating feeling cared for, supported, responsible for their treatment, and many self-reporting adherence without a reminder. Participants in the texting group self-reported adherence on average 77% of the days whereas only 53% in calendar group returned diaries. Exploring initial efficacy, microscopy testing was low and treatment outcomes were similar in both groups. Conclusion. The texting intervention was well accepted and feasible with greater reporting of adherence using text messaging than the diary. Further evaluation of the texting intervention is warranted.

    2016-01-01

    Background Mobile technology to promote exercise is effective; however, most evidence is from studies of younger groups in high-income countries. Investigating if short message service (SMS) texting can affect exercise participation in older adults from an upper-middle-income country is important considering the proliferation of mobile phones in developing regions and the increased interest of older adults in using mobile phones. Objective The main objective was to examine the short- and long-term effects of SMS text messaging on exercise frequency in older adults. Secondary objectives were to investigate how SMS text messages impact study participants’ exercise frequency and the effects of the intervention on secondary outcomes. Methods The Malaysian Physical Activity for Health Study (myPAtHS) was a 24-week, 2-arm, parallel randomized controlled trial conducted in urban Malaysia. Participants were recruited via health talks in resident associations and religious facilities. Older Malaysians (aged 55-70 years) who used mobile phones and did not exercise regularly were eligible to participate in the study. Participants randomly allocated to the SMS texting arm received an exercise booklet and 5 weekly SMS text messages over 12 weeks. The content of the SMS text messages was derived from effective behavior change techniques. The non-SMS texting arm participants received only the exercise booklet. Home visits were conducted to collect outcome data: (1) exercise frequency at 12 and 24 weeks, (2) secondary outcome data (exercise self-efficacy, physical activity–related energy expenditure, sitting time, body mass index, grip and leg strength) at baseline and at 12 and 24 weeks. Intention-to-treat procedures were applied for data analysis. Semistructured interviews focusing primarily on the SMS text messages and their impact on exercise frequency were conducted at weeks 12 and 24. Results In total, 43 participants were randomized into the SMS texting arm (n=22) and

    2016-01-01

    Background Among adults with type 2 diabetes mellitus (T2DM), adherence to recommended self-care activities is suboptimal, especially among racial and ethnic minorities with low income. Self-care nonadherence is associated with having worse glycemic control and diabetes complications. Text messaging interventions are improving the self-care of adults with T2DM, but few have been tested with disadvantaged populations. Objective To develop Rapid Education/Encouragement And Communications for Health (REACH), a tailored, text messaging intervention to support the self-care adherence of disadvantaged patients with T2DM, based on the Information-Motivation-Behavioral skills model. We then tested REACH’s usability to make improvements before evaluating its effects. Methods We developed REACH’s content and functionality using an empirical and theory-based approach, findings from a previously pilot-tested intervention, and the expertise of our interdisciplinary research team. We recruited 36 adults with T2DM from Federally Qualified Health Centers to participate in 1 of 3 rounds of usability testing. For 2 weeks, participants received daily text messages assessing and promoting self-care, including tailored messages addressing users’ unique barriers to adherence, and weekly text messages with adherence feedback. We analyzed quantitative and qualitative user feedback and system-collected data to improve REACH. Results Participants were, on average, 52.4 (SD 9.5) years old, 56% (20/36) female, 63% (22/35) were a racial or ethnic minority, and 67% (22/33) had an income less than US $35,000. About half were taking insulin, and average hemoglobin A1c level was 8.2% (SD 2.2%). We identified issues (eg, user concerns with message phrasing, technical restrictions with responding to assessment messages) and made improvements between testing rounds. Overall, participants favorably rated the ease of understanding (mean 9.6, SD 0.7) and helpfulness (mean 9.3, SD 1.4) of self

    Mobile phone text messages (short message service, SMS) are used pervasively as a form of communication. Almost 100% of the population uses text messaging worldwide and this technology is being suggested as a promising tool in psychiatry. Text messages can be sent either from a classic mobile phone or a web-based application. Reviews are needed to better understand how text messaging can be used in mental health care and other fields of medicine. The objective of the study was to review the literature regarding the use of mobile phone text messaging in mental health care. We conducted a thorough literature review of studies involving text messaging in health care management. Searches included PubMed, PsycINFO, Cochrane, Scopus, Embase and Web of Science databases on May 25, 2015. Studies reporting the use of text messaging as a tool in managing patients with mental health disorders were included. Given the heterogeneity of studies, this review was summarized using a descriptive approach. From 677 initial citations, 36 studies were included in the review. Text messaging was used in a wide range of mental health situations, notably substance abuse (31%), schizophrenia (22%), and affective disorders (17%). We identified four ways in which text messages were used: reminders (14%), information (17%), supportive messages (42%), and self-monitoring procedures (42%). Applications were sometimes combined. We report growing interest in text messaging since 2006. Text messages have been proposed as a health care tool in a wide spectrum of psychiatric disorders including substance abuse, schizophrenia, affective disorders, and suicide prevention. Most papers described pilot studies, while some randomized clinical trials (RCTs) were also reported. Overall, a positive attitude toward text messages was reported. RCTs reported improved treatment adherence and symptom surveillance. Other positive points included an increase in appointment attendance and in satisfaction with

    To evaluate whether text-messaging programs can improve reproductive health among adolescent girls in low- and middle-income countries. We conducted a cluster-randomized controlled trial among 756 female students aged 14 to 24 years in Accra, Ghana, in 2014. We randomized 38 schools to unidirectional intervention (n = 12), interactive intervention (n = 12), and control (n = 14). The unidirectional intervention sent participants text messages with reproductive health information. The interactive intervention engaged adolescents in text-messaging reproductive health quizzes. The primary study outcome was reproductive health knowledge at 3 and 15 months. Additional outcomes included self-reported pregnancy and sexual behavior. Analysis was by intent-to-treat. From baseline to 3 months, the unidirectional intervention increased knowledge by 11 percentage points (95% confidence interval [CI] = 7, 15) and the interactive intervention by 24 percentage points (95% CI = 19, 28), from a control baseline of 26%. Although we found no changes in reproductive health outcomes overall, both unidirectional (odds ratio [OR] = 0.14; 95% CI = 0.03, 0.71) and interactive interventions (OR = 0.15; 95% CI = 0.03, 0.86) lowered odds of self-reported pregnancy for sexually active participants. Text-messaging programs can lead to large improvements in reproductive health knowledge and have the potential to lower pregnancy risk for sexually active adolescent girls.

    Objective: To do a clinical and ultrasonic evaluation of subjects with thumb pain with text messaging. Background: Thumbs are commonly used for text messaging, which are not as well designed for fine manipulative or dexterous work. Repetitive use as in text messaging can lead to the injury to the tendons of the thumb. Materials and Methods: Ninety eight students with symptoms of Repetitive Strain Type of injuries of the thumb were selected from a survey and evaluated both clinically and by ultrasound analysis of the musculotendinous unit of the thumb to note changes due to excessive use of the mobile phone. Age and sex matched controls were also subjected to ultrasound evaluation. Results: Clinical examination showed positive Finkelstein test in 40% of the cases, significant reduction in the lateral and tip pinch strengths in the cases. Ultrasound detected changes in the first and the third compartments in 19% of the cases. Conclusion: Isolated cases of pain in the thumb have been reported but this study noted changes both clinically and by ultrasound in the tendons of the thumb. These changes should be taken as warning signs of possible subclinical changes taking place in the soft tissues of the thumb in these subjects due to repetitive use of mobile phones and thus, making them prone for developing painful Musculoskeletal Disorders. Application: Repetitive use of mobile phones for text messaging can lead to the damage of Extensor pollicis longus of the thumb in addition to the tendons of the first compartment of the wrist.

    Alaska Native and American Indian people (AN/AIs) have a high incidence of colorectal cancer (CRC) and CRC-related mortality. Screening can prevent death from CRC, but screening rates are low in racially and ethnically diverse populations. The authors conducted a randomized controlled trial using text messaging to increase CRC screening among unscreened AN/AIs in a tribal health care system in Anchorage, Alaska. The intervention entailed up to 3 text messages sent 1 month apart. The authors randomized 2386 AN/AIs aged 40 to 75 years who were eligible for CRC screening to the intervention or usual-care control conditions. Screening status was ascertained from electronic health records 3 months and 6 months after the last text message. Hazard ratios (HRs) were estimated to evaluate the effectiveness of the intervention, stratified by age and sex. The intervention increased CRC screening for AN/AIs aged 50 to 75 years (HR, 1.42; 95% confidence interval [95% CI], 0.97-2.09) and aged 40 to 49 years (HR, 1.24; 95% CI, 0.95-1.62). Within both age groups, the HRs were higher for women (HR, 1.69 [95% CI, 1.02-2.80] and HR, 1.37 [95% CI, 1.01-1.88]) compared with men (HR, 1.09 [95% CI, 0.59-1.99] and HR, 0.90 [95% CI, 0.54-1.53]). Interaction analysis yielded P values of .55 and .09, respectively, for age and sex. A simple text messaging intervention was found to increase CRC screening rates in AN/AIs, a group with high CRC morbidity and mortality. Text messaging may be a cost-effective means of reducing CRC screening disparities in AN/AIs and other populations.

    Inadequate medication adherence reduces optimal health outcomes and can lead to increased costs, particularly in patients with diabetes. Efforts to improve adherence have resulted in limited effects; approaches leveraging mobile technology have emerged, but their focus has mainly been limited to simple reminder messages. The purpose of this pilot study was to test the effectiveness of tailored text messages focusing on improving medication adherence and health beliefs in adults with diabetes. Adults aged 21-64, with uncontrolled diabetes, and taking at least one anti-diabetic medication were recruited and randomized into 2 study arms: daily tailored text messaging for 90 days or standard care. Comparing baseline and endpoint survey responses, changes in theory-driven health beliefs and attitudes were assessed. The impact on medication adherence was evaluated using pharmacy claims by calculating the percent of days covered (PDC). A total of 75 subjects were consented, and 48 were randomized. Mean PDC at baseline were comparable between cohorts (84.4% and 87.1%, respectively). Declines in adherence were observed in both groups over time but no significant differences were observed between groups or from baseline to the end of the active study period. Unadjusted tests suggested that perceived benefits and competence might have improved in the intervention arm. Tailoring mobile phone text messages is a novel way to address medication nonadherence and health beliefs; further investigation to this combined technique is needed to better understand its impact on behavior change in adults with diabetes.

    This study examined the effects of text message content (generic vs. culturally tailored) on the login rate of an Internet physical activity program in Hong Kong Chinese adolescent school children. A convenience sample of 252 Hong Kong secondary school adolescents (51% female, 49% male; M age = 13.17 years, SD = 1.28 years) were assigned to one of 3 treatments for 8 weeks. The control group consisted of an Internet physical activity program. The Internet plus generic text message group consisted of the same Internet physical activity program and included daily generic text messages. The Internet plus culturally tailored text message group consisted of the Internet physical activity program and included daily culturally tailored text messages. Zero-inflated Poisson mixed models showed that the overall effect of the treatment group on the login rates varied significantly across individuals. The login rates over time were significantly higher in the Internet plus culturally tailored text message group than the control group (β = 46.06, 95% CI 13.60, 156.02; p = .002) and the Internet plus generic text message group (β = 15.80, 95% CI 4.81, 51.9; p = .021) after adjusting for covariates. These findings suggest that culturally tailored text messages may be more advantageous than generic text messages on improving adolescents' website login rate, but effects varied significantly across individuals. Our results support the inclusion of culturally tailored messaging in future online physical activity interventions.

    Full Text Available Background. Maternal obesity and excessive gestational weight gain (GWG are on the rise with negative impact on pregnancy and birth outcomes. Research into managing GWG using accessible technology is limited. The maternal obesity management using mobile technology (MOMTech study aimed at evaluating the feasibility of text messaging based complex intervention designed to support obese women (BMI ≥ 30 with healthier lifestyles and limit GWG. Methods. Participants received two daily text messages, supported by four appointments with healthy lifestyle midwife, diet and activity goal setting, and self-monitoring diaries. The comparison group were obese mothers who declined to participate but consented for their routinely collected data to be used for comparison. Postnatal interviews and focus groups with participants and the comparison group explored the intervention’s acceptability and suggested improvements. Results. Fourteen women completed the study which did not allow statistical analyses. However, participants had lower mean GWG than the comparison group (6.65 kg versus 9.74 kg and few (28% versus 50% exceeded the Institute of Medicine’s upper limit of 9 kg GWG for obese women. Conclusions. MOMTech was feasible within clinical setting and acceptable intervention to support women to limit GWG. Before further trials, slight modifications are planned to recruitment, text messages, and the logistics of consultation visits.

    Full Text Available Abstract Background Smoking is still the leading cause of preventable ill health and death. There is a limited amount of evidence for effective smoking cessation interventions among young people. To address this, a text messaging-based smoking cessation programme, the NEXit intervention, was developed. Short-term effectiveness, measured immediately after the 12-week intervention revealed that 26% of smokers in the intervention group had prolonged abstinence compared with 15% in the control group. The present study was performed to explore the users’ experiences of the structure and content of the intervention in order to further develop the intervention. Methods Students participating in the main NEXit randomized controlled trial were invited to grade their experiences of the structure and content of the intervention after having completed follow-up. The participants received an e-mail with an electronic link to a short questionnaire. Descriptive analysis of the distribution of the responses to the questionnaire was performed. Free-text comments to 14 questions were analysed. Results The response rate for the user feedback questionnaire was 35% (n = 289/827 and 428 free-text comments were collected. The first motivational phase of the intervention was appreciated by 55% (158/289 of the participants. Most participants wanted to quit smoking immediately and only 124/289 (43% agreed to have to decide a quit-date in the future. Most participants 199/289 (69% found the content of the messages in the core programme to be very good or good, and the variability between content types was appreciated by 78% (224/289. Only 34% (97/289 of the participants thought that all or nearly all messages were valuable, and some mentioned that it was not really the content that mattered, but that the messages served as a reminder about the decision to quit smoking. Conclusions The programme was largely perceived satisfactory in most aspects concerning structure

    Full Text Available Abstract Background Mobile health (mHealth is emerging as a useful tool to improve healthcare access especially in the developing world, where limited access to health services is linked to poor antenatal care, and maternal and perinatal mortality. The objective of this study is to 1 understand pregnant women’s access and usage of cell phones and 2 survey the health information needs and interests in a population attending public hospitals and health centers of two cities in Argentina. This information is not available and it is the basis to develop a strategy for improving maternal care via cell phones. Methods Questionnaires were verbally administered to pregnant women who were attending an antenatal care visit in community health centers and public hospitals in Rosario, Santa Fe and Mercedes, Corrientes. Participants were 18 years of age or older and had previously given birth. The data obtained was qualitative and analyzed using SPSS version 18. Results A total of 147 pregnant women meeting inclusion criteria (Rosario: 63; Mercedes: 84 were approached and verbally consented to participate. The average age was 29.5 years, most lived in urban areas (89% with a mean travel time of 43.4 minutes required to get to the health center and 57.3 minutes to get the hospital. Ninety-six percent of women (n = 140 responded that they would like to receive text messages and cell phone calls with information regarding prenatal care, although the topics and period of time to receive information varied greatly. Conclusions Considering the vast majority of the interviewed women had access to and were interested in receiving text messages and calls with educational information regarding pregnancy and infant health, pregnant women in Argentina could benefit from such an mHealth program. The low access to Internet suggests it is not an option for this population; however, this cannot be assumed as representative of the country’s situation. To retain

    Text messaging interventions for health are becoming increasingly popular, but it is unclear how rigorously such interventions are developed and pretested before being implemented. Pretesting is important to the development of successful health communication interventions. This study reviewed the literature published on text messaging health behavior change interventions and examined pretesting practices. Results showed that pretesting is rarely mentioned in articles, although it is not clear as to why. Six articles mentioned pretesting practices conducted for their mobile intervention, and three articles were written specifically on the pretesting of an intervention. Most pretesting used qualitative methods. Recommendations are provided on pretesting best practices and pretesting reporting to help other researchers in the field of mobile health.

    We evaluated the effectiveness of text messaging versus email, as a delivery method to enhance knowledge retention of emergency medicine (EM) content in EM residents. We performed a multi-centered, prospective, randomized study consisting of postgraduate year (PGY) 1 to PGY 3 & 4 residents in three United States EM residency programs in 2014. Fifty eight residents were randomized into one delivery group: text message or email. Participants completed a 40 question pre- and post-intervention exam. Primary outcomes were the means of pre- and post-intervention exam score differences. Data were analyzed using descriptive statistics, paired t-test, and multiple linear regressions. No significant difference was found between the primary outcomes of the two groups (P=0.51). PGY 2 status had a significant negative effect (P=0.01) on predicted exam score difference. Neither delivery method enhanced resident knowledge retention. Further research on implementation of mobile technology in residency education is required.

    Bullying is a significant public health issue among middle school-aged youth. Current prevention programs have only a moderate impact. Cell phone text messaging technology (mHealth) can potentially overcome existing challenges, particularly those that are structural (e.g., limited time that teachers can devote to non-educational topics). To date, the description of the development of empirically-based mHealth-delivered bullying prevention programs are lacking in the literature. To describe the development of BullyDown, a text messaging-based bullying prevention program for middle school students, guided by the Social-Emotional Learning model. We implemented five activities over a 12-month period: (1) national focus groups (n=37 youth) to gather acceptability of program components; (2) development of content; (3) a national Content Advisory Team (n=9 youth) to confirm content tone; and (4) an internal team test of software functionality followed by a beta test (n=22 youth) to confirm the enrollment protocol and the feasibility and acceptability of the program. Recruitment experiences suggested that Facebook advertising was less efficient than using a recruitment firm to recruit youth nationally, and recruiting within schools for the pilot test was feasible. Feedback from the Content Advisory Team suggests a preference for 2-4 brief text messages per day. Beta test findings suggest that BullyDown is both feasible and acceptable: 100% of youth completed the follow-up survey, 86% of whom liked the program. Text messaging appears to be a feasible and acceptable delivery method for bullying prevention programming delivered to middle school students.

    Tonsillectomy is the most common type of surgical procedure performed in preschool children. Due to short period of hospitalization, mothers are expected to manage their children's care at home. However, they are rarely provided with sufficient information about postoperative management. This study aims to determine the effectiveness of providing caregivers with information on tonsillectomy care by smartphone text messaging in increasing their mothers' knowledge, reducing the anxiety, and improving the sick-role behavior of pediatric tonsillectomy patients. A sample of 61 pediatric patients and their mothers was recruited. Participants were randomly assigned into either the experimental group (n = 27) or the control group (n = 34). The control group was given information about the tonsillectomy by conventional textual and verbal means, whereas the experimental group received the same information in the form of 10 text messages during the period from hospitalization to their first follow-up visits. Results of mixed design, two-way analysis of variance indicated significant interaction effects between time points and groups for mothers' knowledge (F = 4.26, p = 0.043) and children's anxiety (F = 3.32; p = 0.037). Thus, the results do support the effectiveness of tonsillectomy education using smartphone text messaging in increasing mothers' knowledge and reducing children's anxiety. These results can be applied to preoperative and postoperative interventions for children not only for tonsillectomy but also for many other operations. The development of various educational programs using smartphone text messaging for postoperative patient management would also be valuable.

    Text-message and e-mail are emerging as potential methods for improving weight outcomes among obese individuals. The optimal volume, frequency, and timing of such interventions are unknown. This study investigated the effect of adjunct technological support on weight and psychological variables after a 3-month cognitive-behaviour therapy (CBT) group intervention. Sixty obese adults were randomised to a CBT programme plus intensive (text-message and e-mail; CBT+ITS) or minimal (text-message only; CBT+MTS) technological support. Assessments occurred at baseline, 3-, 6-, 9-, and 15-months. Outcome variables included weight (kg), body mass index (kg/m 2 ), waist circumference (cm), binge-eating tendencies, weight self-efficacy, and weight control cognitions and behaviours. CBT+ITS (n=31) and CBT+MTS (n=29) participants lost 5.2% (±1.1) and 4.7% (±1.1) of their baseline weight by 3-months, 8.4% (±1.2) and 6.4% (±1.1) by 6-months, 9.6% (±1.3) and 6.4% (±1.3) by 9-months, and sustained a 7.5% (±1.3) and 5.1% (±1.3) loss at 15-months, respectively. There were no significant differences between intensive and minimal support, however, the CBT+ITS group showed a marginal advantage across all anthropometric measures. A low intensity text-message support programme is just as effective as higher intensity technological support for maintaining weight loss in obese adults. This represents a low-cost means of aiding weight loss maintenance without reliance on extended face-to-face treatment. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Obesity has become a worldwide epidemic. Qatar, a rapidly developing country in the Middle East, has seen a sharp increase in the prevalence of obesity. The increase can be attributed to several reasons, including sedentary lifestyles imposed by a harsh climate and the introduction of Western fast food. Mobile technologies have been used and studied as a technology to support individuals’ weight loss. The authors have developed a mobile application that implements three strategies drawn from proven theories of behavioral change. The application is localized to the cultural context of its proposed users. The objective of this paper is to present a method through which we adapted the messaging content of a weight loss application to the context of its users while retaining an effective degree of automation. The adaptation addressed body image, eating and physical exercise habits, and regional/cultural needs. The paper discusses how surveying potential users can be used to build a profile of a target population, find common patterns, and then develop a database of text messages. The text messages are automated and sent to the users at specific times of day, as suggested by the survey results.

    Text messages are increasingly being used because of the low cost and the ubiquitous nature of mobile phones to engage patients in self-care behaviors. Self-care is particularly important in achieving treatment outcomes in type 2 diabetes mellitus (T2DM). This study examined the effect of personalized text messages on physical activity, as measured by a pedometer, and clinical outcomes in a diverse population of patients with T2DM. Text to Move (TTM) incorporates physical activity monitoring and coaching to provide automated and personalized text messages to help patients with T2DM achieve their physical activity goals. A total of 126 English- or Spanish-speaking patients with glycated hemoglobin A1c (HbA1c) >7 were enrolled in-person to participate in the study for 6 months and were randomized into either the intervention arm that received the full complement of the intervention or a control arm that received only pedometers. The primary outcome was change in physical activity. We also assessed the effect of the intervention on HbA1c, weight, and participant engagement. All participants (intervention: n=64; control: n=62) were included in the analyses. The intervention group had significantly higher monthly step counts in the third (risk ratio [RR] 4.89, 95% CI 1.20 to 19.92, P=.03) and fourth (RR 6.88, 95% CI 1.21 to 39.00, P=.03) months of the study compared to the control group. However, over the 6-month follow-up period, monthly step counts did not differ statistically by group (intervention group: 9092 steps; control group: 3722 steps; RR 2.44, 95% CI 0.68 to 8.74, P=.17). HbA1c decreased by 0.07% (95% CI -0.47 to 0.34, P=.75) in the TTM group compared to the control group. Within groups, HbA1c decreased significantly from baseline in the TTM group by -0.43% (95% CI -0.75 to -0.12, P=.01), but nonsignificantly in the control group by -0.21% (95% CI -0.49 to 0.06, P=.13). Similar changes were observed for other secondary outcomes. Personalized text messaging

    The aim of our study was to examine the association between problematic cell phone use (PCPU) for text messaging and substance abuse in young adolescents. This cross-sectional study was conducted on the basis of an ad hoc questionnaire, during the 2014-2015 school year in a province of the Veneto Region (Italy); it involved a sample of 1156 students in grades 6 to 8 (11 to 13 years old). A self-report scale based on the Short Message Service (SMS) Problem Use Diagnostic Questionnaire (SMS-PUDQ) was administered to assess the sample's PCPU. A multivariate logistic regression model was applied to seek associations between PCPU (as the dependent variable) and independent variables. The proportion of students who reported a PCPU increased with age in girls (13.5% in 6th grade, 16.4% in 7th grade, and 19.5% in 8th grade), but not in boys (14.3% in 6th grade, 18.0% in 7th grade, and 14.8% in 8th grade). Logistic regression showed that drunkenness at least once and energy drink consumption raised the odds of PCPU, whereas reading books, higher average school marks, and longer hours of sleep were associated with lower odds of PCPU in early adolescence. our findings confirm a widespread PCPU for text messaging among early adolescents. The odds of PCPU is greater in young people at risk of other substance abuse behavior.

    To carry out a randomised controlled trial on the effect of a new method of health promotion-email and mobile phone text messages (short messaging service (SMS))-on young people's sexual health. 994 people aged 16-29 were recruited at a music festival to a non-blinded randomised controlled trial. Participants were randomised to either receive sexual health promotion messages (n=507) or the control group (n=487). The 12-month intervention included SMS (catchy sexually transmissible infections prevention slogans) and emails. Participants completed questionnaires at the festival at baseline and online after 3, 6 and 12 months. Outcomes were differences between the control and intervention groups in health-seeking behaviour, condom use with risky partners (new or casual partners or two or more partners within 12 months) and STI knowledge. 337 (34%) completed all three follow-up questionnaires and 387 (39%) completed the final questionnaire. At 12 months, STI knowledge was higher in the intervention group for both male (OR=3.19 95% CI 1.52 to 6.69) and female subjects (OR=2.36 95% CI 1.27 to 4.37). Women (but not men) in the intervention group were more likely to have had an STI test (OR=2.51, 95% CI 1.11 to 5.69), or discuss sexual health with a clinician (OR=2.92, 95% CI 1.66 to 5.15) than their control counterparts. There was no significant impact on condom use. Opinions of the messages were favourable. This simple intervention improved STI knowledge in both sexes and STI testing in women, but had no impact on condom use. SMS and email are low cost, popular and convenient, and have considerable potential for health promotion. Australian Clinical Trials Registry - ACTRN12605000760673.

    Hand preference for sending mobile-phone text messages ("texting") and its relationship with hand preference for other activities were investigated in a questionnaire study with 886 participants. Overall rates of both sinistrality and dextrality were reduced for texting, in comparison with other activities, due to the substantial number of individuals who use both hands simultaneously when performing this activity. Because they both involve verbal expression, it was hypothesised that the association between hand preferences for texting and writing might be stronger than the association between either of these tasks and more spatial activities, such as throwing. This prediction was not confirmed, either in the sample as a whole or in a sub-group of individuals who reported writing and throwing with opposite hands. Females were less likely than males to use their left hand when sending text messages. Implications of these findings are discussed, in relation to theoretical views of handedness and in relation to practical aspects of mobile-phone design.

    The number of adolescents with chronic health conditions (CHCs) continues to increase. Medication nonadherence is a global challenge among adolescents across chronic conditions and is associated with poor health outcomes. While there has been growing interest in the use of mHealth technology to improve medication adherence among adolescents with CHCs, particularly text messaging and mobile phone apps, there has been no prior systematic review of their efficacy. The purpose of this review was to systematically evaluate the most recent evidence for the efficacy of text messaging and mobile phone apps as interventions to promote medication adherence among adolescents with CHCs. PubMed, Embase, CENTRAL, PsycINFO, Web of Science, Google Scholar, and additional databases were searched from 1995 until November 2015. An additional hand search of related themes in the Journal of Medical Internet Research was also conducted. The Preferred Reporting Results of Systematic Reviews and Meta-Analyses guidelines were followed. Two reviewers independently screened titles/abstracts, assessed full-text articles, extracted data from included articles, and assessed their quality using Grades of Recommendation, Assessment, Development, and Evaluation criteria. Included studies were described in original research articles that targeted adherence in adolescents with CHCs (12-24 years-old). Of the 1423 records examined, 15 met predefined criteria: text messaging (n=12) and mobile phone apps (n=3). Most studies were performed in the United States (11/15, 73%), were randomized-controlled trials (8/15, 53%), had a sample size mobile phone app interventions varied across studies. Seven articles (7/15, 47%) reported significant improvement in adherence with moderate to large standardized mean differences. Most of the included studies were of low or moderate quality. Studies varied in sample size, methods of adherence assessment, and definition of adherence, which prohibited performing a meta

    To determine the effectiveness of a mobile phone text messaging smoking cessation programme. Randomised controlled trial New Zealand 1705 smokers from throughout New Zealand who wanted to quit, were aged over 15 years, and owned a mobile phone were randomised to an intervention group that received regular, personalised text messages providing smoking cessation advice, support, and distraction, or to a control group. All participants received a free month of text messaging; starting for the intervention group on their quit day to assist with quitting, and starting for the control group at six months to encourage follow up. Follow up data were available for 1624 (95%) at six weeks and 1265 (74%) at six months. The main trial outcome was current non-smoking (that is, not smoking in the past week) six weeks after randomisation. Secondary outcomes included current non-smoking at 12 and 26 weeks. More participants had quit at six weeks in the intervention compared to the control group: 239 (28%) v 109 (13%), relative risk 2.20 (95% confidence interval 1.79 to 2.70), p 0.2). The relative risk estimates were similar in sensitivity analyses adjusting for missing data and salivary cotinine verification tests. Reported quit rates remained high at six months, but there was some uncertainty about between group differences because of incomplete follow up. This programme offers potential for a new way to help young smokers to quit, being affordable, personalised, age appropriate, and not location dependent. Future research should test these findings in different settings, and provide further assessment of long term quit rates.

    Brief, web-based motivational interventions have shown promising results for reducing alcohol use and associated harm among college students. However, findings regarding which alcohol use outcomes are impacted are mixed and effects tend to be small to moderate, with effect sizes decreasing over longer-term follow-up periods. As a result, these interventions may benefit from adjunctive strategies to bolster students' engagement with intervention material and to extend interventions beyond initial contacts into student's daily lives. This study tested the efficacy of text messaging as an adjunct to a web-based intervention for heavy episodic drinking college students. One-hundred and thirteen undergraduate student risky drinkers recruited from an introductory psychology class were randomly assigned to one of three conditions-assessment only (AO), web intervention (WI), and web intervention plus text messaging (WI+TXT). Heavy drinking episodes (HDEs), weekend quantity per occasion, and alcohol-related consequences were assessed at baseline and one month follow-up. Univariate analysis of covariance (ANCOVA) was used to assess the influence of condition assignment on 1-month outcomes, controlling for baseline variables. Planned contrasts showed that those in the WI+TXT condition showed significantly less weekend drinking than those in the AO and WI conditions. Although those in the WI+TXT condition showed significantly fewer HDEs compared to AO, it was not significantly different than the WI only condition. No differences were observed on alcohol-related problems. These findings provide partial support for the view that text messaging may be a useful adjunct to web-based interventions for reducing alcohol consumption among student drinkers. Copyright © 2017.

    Text messaging (short message service, SMS) is a widely accessible and potentially cost-effective medium for encouraging behavior change. Few studies have examined text messaging interventions to influence child health behaviors or explored parental perceptions of mobile technologies to support behavior change among children. Our aim was to examine parental acceptability and preferences for text messaging to support pediatric obesity-related behavior change. We conducted focus groups and follow-up interviews with parents of overweight and obese children, aged 6-12 years, seen for "well-child" care in eastern Massachusetts. A professional moderator used a semistructured discussion guide and sample text messages to catalyze group discussions. Seven participants then received 3 weeks of text messages before a follow-up one-on-one telephone interview. All focus groups and interviews were recorded and transcribed verbatim. Using a framework analysis approach, we systematically coded and analyzed group and interview data to identify salient and convergent themes. We reached thematic saturation after five focus groups and seven follow-up interviews with a total of 31 parents of diverse race/ethnicity and education levels. Parents were generally enthusiastic about receiving text messages to support healthy behaviors for their children and preferred them to paper or email communication because they are brief and difficult to ignore. Participants anticipated high responsiveness to messaging endorsed by their child's doctor and indicated they would appreciate messages 2-3 times/week or more as long as content remains relevant. Suggestions for maintaining message relevance included providing specific strategies for implementation and personalizing information. Most felt the negative features of text messaging (eg, limited message size) could be overcome by providing links within messages to other media including email or websites. Text messaging is a promising medium for

    Background Text messaging (texting) has become a routine medium of communication in society. However, its use among clinicians has not been fully characterized. We explored general surgery residents' practices and views on texting for patient-related communication. Methods An email survey was distributed to all general surgery residents at a large Canadian medical school. Results Overall, 46 (57%) of those surveyed responded. All used texting for patient-related communication. Eleven percent of residents did not have a password on their cell phone and 89% did not have encrypted phones. Texting was the most common way (41%) by which residents communicated routine patient-related information with staff physicians. Most (85%) residents agreed that texting enhances patient care. The majority (66%) did not know if their hospital had a policy on texting and were unaware of legislation surrounding texting in patient care (89%). Conclusions Most general surgery residents use texting for communication of routine patient-related care issues. However, they acknowledge concerns regarding the security of this medium. © The Author(s) 2016.

    This study identified the extent and nature of engagement with a theoretically based behaviour change text message intervention intended to reduce binge drinking. The data were from a randomised controlled trial tackling binge drinking among socially disadvantaged men. An intervention, comprising 112 text messages, and based on the principles of the Health Action Process Approach, was delivered to 411 socially disadvantaged men. Participants sent almost 7500 responses to the text messages. Engagement was assessed by whether text message replies showed the intended response to key components of the behaviour change strategy. The median number of responses to the text messages was 17 per man (range 0-81). Men often gave detailed sensitive personal information about their drinking and the harms it caused them. They also described their attempts at drinking less, the setbacks encountered and the benefits they enjoy when they are successful at cutting down. Specific examples of engagement with the targeted messages include the following: of the 248 men who responded to the prompt on outcome expectancies, most (230) identified potential benefits of cutting down; for intention to reduce drinking, 260 men responded of whom 44% said they had thought about changing; of the 172 men who responded to the question on goal setting, 158 reported personal goals. The responses showed that most men engaged as intended with the key components of the intervention. Text message interventions should include questions addressing key components of the behaviour change strategy to determine whether there is effective engagement with intervention components.

Research articles published during 2011 to 2014; analyses focused on intervention targeting adolescents (10-19 years), with healthy lifestyle behaviors as main variables, delivered via mobile phone-based TM. The authors extracted data from 27 of 281 articles using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method. Adolescent and setting characteristics, study design and rigor, intervention effectiveness, challenges, and risk of bias. Across studies, 16 (59.3%) of 27 included non-Caucasians. The gender was split for 22 (81.5%) of 27 studies. Thirteen studies were randomized controlled trials. There was heterogeneity among targeted conditions, rigor of methods, and intervention effects. Interventions for monitoring/adherence (n = 8) reported more positive results than those for health behavior change (n = 19). Studies that only included message delivered via TM (n = 14) reported more positive effects than studies integrating multiple intervention components. Interventions delivered using TM presented minimal challenges, but selection and performance bias were observed across studies. Interventions delivered using TM have the potential, under certain conditions, to improve healthy lifestyle behaviors in adolescents. However, the rigor of studies varies, and established theory and validated measures have been inconsistently incorporated. © The Author(s) 2016.

    Infant mortality is associated with access to healthcare, knowledge, and health literacy. Text4baby, the largest national texting health initiative, seeks to address these factors. However, no research has examined the program's theoretical framework, an aspect that may impact its success. To address this gap, Text4baby's use of theory was evaluated through a content analysis of Text4baby messages and interviews with Text4baby content developers. We compared the main variables of health behavior theories framing Text4baby messages with the situational theory of publics and its factors of problem recognition and constraint recognition. The situational theory of publics provides an understanding of the types of publics that might emerge from Text4baby's audiences of pregnant women. Aware, latent, and active publics are defined by the situational theory and are created out of problem recognition and constraint recognition along with a level of personal involvement in the issue of prenatal health. We used content analysis and interviewing to explore how Text4baby prenatal messages were constructed using theory and to offer lessons learned for prenatal health campaigns. The multi-methodological approach to understanding meaning construction in the production of these text messages and how meaning played out in the messages is a useful framework for text message campaigns.

    Full Text Available BACKGROUND: Process evaluation is essential in developing, piloting and evaluating complex interventions. This often involves observation of intervention delivery and interviews with study participants. Mobile telephone interventions involve no face to face contact, making conventional process evaluation difficult. This study assesses the utility of novel techniques for process evaluation involving no face to face contact. METHODS: Text messages were delivered to 34 disadvantaged men as part of a feasibility study of a brief alcohol intervention. Process evaluation focused on delivery of the text messages and responses received from study participants. The computerized delivery system captured data on receipt of the messages. The text messages, delivered over 28 days, included nine which asked questions. Responses to these questions served as one technique for process evaluation by ascertaining the nature of engagement with the study and with steps on the causal chain to behavior change. RESULTS: A total of 646 SMS text messages were sent to participants. Of these, 613 messages (95% were recorded as delivered to participants' telephones. 88% of participants responded to messages that asked questions. There was little attenuation in responses to the questions across the intervention period. Content analysis of the responses revealed that participants engaged with text messages, thought deeply about their content and provided carefully considered personal responses to the questions. CONCLUSIONS: Socially disadvantaged men, a hard to reach population, engaged in a meaningful way over a sustained period with an interactive intervention delivered by text message. The novel process measures used in the study are unobtrusive, low cost and collect real-time data on all participants. They assessed the fidelity of delivery of the intervention and monitored retention in the study. They measured levels of engagement and identified participants' reactions to

    Patient-provider communication is a major challenge in resource-limited settings with large catchment areas. Though mobile phone usership increased 20-fold in Africa over the past decade, little is known about acceptability of, perceptions about disclosure and confidentiality, and preferences for cell phone communication of health information in the region. We performed structured interviews of fifty patients at the Immune Suppression Syndrome clinic in Mbarara, Uganda to assess four domains of health-related communication: a) cell phone use practices and literacy, b) preferences for laboratory results communication, c) privacy and confidentiality, and d) acceptability of and preferences for text messaging to notify patients of abnormal test results. Participants had a median of 38 years, were 56% female, and were residents of a large catchment area throughout southwestern Uganda. All participants expressed interest in a service to receive information about laboratory results by cell phone text message, stating benefits of increased awareness of their health and decreased transportation costs. Ninety percent reported that they would not be concerned for unintended disclosure. A minority additionally expressed concerns about difficulty interpreting messages, discouragement upon learning bad news, and technical issues. Though all respondents expressed interest in password protection of messages, there was also a strong desire for direct messages to limit misinterpretation of information. Cell phone text messaging for communication of abnormal laboratory results is highly acceptable in this cohort of HIV-infected patients in rural Uganda. The feasibility of text messaging, including an optimal balance between privacy and comprehension, should be further studied.

    Reproducible outcomes in clinical trials depend on adherence to study protocol. Short message service (also known as text message) reminders have been shown to improve clinical trial adherence in the United States and elsewhere. However, due to systematic differences in mobile data plans, languages, and technology, these systems are not easily translated to international settings. To gauge technical capabilities for international projects, we developed SMSMessenger, an automated Android application that uses a US server to send medication reminders to participants in a clinical trial in St. Petersburg, Russia (Zinc for HIV disease among alcohol users-a randomized controlled trial in the Russia Alcohol Research Collaboration on HIV/AIDS cohort). The application is downloaded once onto an Android study phone. When it is time for the text message reminders to be sent, study personnel access the application on a local phone, which in turn accesses the existing clinical trial database hosted on a US web server. The application retrieves a list of participants with the following information: phone number, whether a message should be received at that time, and the appropriate text of the message. The application is capable of storing multiple outgoing messages. With a few clicks, text messages are sent to study participants who can reply directly to the message. Study staff can check the local phone for incoming messages. The SMSMessenger application uses an existing clinical trial database and is able to receive real-time updates. All communications between the application and server are encrypted, and phone numbers are stored in a secure database behind a firewall. No sensitive data are stored on the phone, as outgoing messages are sent through the application and not by messaging features on the phone itself. Messages are sent simultaneously to study participants, which reduces the burden on local study staff. Costs and setup are minimal. The only local requirements

    Background Smoking prevalence remains high, particularly among adolescents and young adults with lower educational levels, posing a serious public health problem. There is limited evidence of effective smoking cessation interventions in this population. Objective To test the efficacy of an individually tailored, fully automated text messaging (short message service, SMS)–based intervention for smoking cessation in young people. Methods A 2-arm cluster randomized controlled trial, using school class as the randomization unit, was conducted to test the efficacy of the SMS text messaging intervention compared to an assessment-only control group. Students who smoked were proactively recruited via online screening in vocational school classes. Text messages, tailored to demographic and smoking-related variables, were sent to the participants of the intervention group at least 3 times per week over a period of 3 months. A follow-up assessment was performed 6 months after study inclusion. The primary outcome measure was 7-day smoking abstinence. Secondary outcomes were 4-week smoking abstinence, cigarette consumption, stage of change, and attempts to quit smoking. We used regression models controlling for baseline differences between the study groups to test the efficacy of the intervention. Both complete-case analyses (CCA) and intention-to-treat analyses (ITT) were performed. Subgroup analyses were conducted for occasional and daily smokers. Results A total of 2638 students in 178 vocational school classes in Switzerland participated in the online screening. Overall, 1012 persons met the inclusion criteria for study participation, and 755 persons (74.6%) participated in the study (intervention: n=372; control: n=383). Of the 372 program participants, 9 (2.4%) unsubscribed from the program during the intervention period. Six-month follow-up data were obtained for 559 study participants (74.0%). The 7-day smoking abstinence rate at follow-up was 12.5% in the

    Hispanics represent a critical target for culturally adapted diet interventions. In this formative research, we translated HealthyYouTXT, an mHealth program developed by the U.S. National Cancer Institute, into HealthyYouTXT en Español, a linguistically and culturally appropriate version for Spanish speakers in the United States. We report a three-stage, mixed-methods process through which we culturally adapted the text messages, evaluated their acceptability, and revised the program based on the findings. In Stage 1, we conducted initial translations and adaptations of the text libraries using an iterative, principle-guided process. In Stage 2, we used mixed methods including focus groups and surveys with 109 Hispanic adults to evaluate the acceptability and cultural appropriateness of the program. We used survey data to evaluate whether self-determination theory (SDT) factors (used to develop HealthyYouTXT) of autonomous motivation, controlled motivation, and amotivation and Hispanic cultural beliefs about familism, fatalism, and destiny predict program interest and its perceived efficacy. Mixed-methods analyses revealed substantial interest in HealthyYouTXT, with most participants desiring to use it and viewing it as highly efficacious. Both cultural beliefs (i.e., beliefs in destiny and, for men, high familism) and SDT motivations (i.e., autonomy) predicted HealthyYouTXT evaluations, suggesting utility in emphasizing them in messages. Higher destiny beliefs predicted lower interest, suggesting that they could impede program use. In Stage 3, we implemented the mixed-methods findings to finalize HealthyYouTXT en Español. The emergent linguistic principles and multistage, multimethods process can be applied in health communication adaptations.

  15. Comparison of text messaging and paper-and-pencil for ecological momentary assessment of food craving and intake.

    Electronic devices such as mobile phones are quickly becoming a popular way to gather participant reports of everyday thoughts, feelings, and behaviors, including food cravings and intake. Electronic devices offer a number of advantages over alternative methods such as paper-and-pencil (PNP) assessment including automated prompts, on-the-fly data transmission, and participant familiarity with and ownership of the devices. However, only a handful of studies have systematically compared compliance between electronic and PNP methods of ecological momentary assessment (EMA), and none have examined eating specifically. Existing comparisons generally find greater compliance for electronic devices than PNP, but there is variability in the results across studies that may be accounted for by differences across research domains. Here, we compared the two EMA methods in an unexamined domain - eating - in terms of response rate and response latency, and their sensitivity to individual difference variables such as body mass index (BMI). Forty-four participants were randomly assigned to report on their food craving, food intake, and hunger four times each day for 2 weeks using either a PNP diary (N = 19) or text messaging (TXT; N = 25). Response rates were higher for TXT than PNP (96% vs. 70%) and latencies were faster (29 min vs. 79 min), and response rate and latency were less influenced by BMI in the TXT condition than in the PNP condition. These results support the feasibility of using text messaging for EMA in the eating domain, and more broadly highlight the ways that research domain-specific considerations (e.g., the importance of response latency in measuring short-lived food craving) interact with assessment modality during EMA.

This randomized trial tested the efficacy of a 12-week interactive text message intervention to reduce binge drinking up to 6 months after intervention completion among young adults.Young adult participants (18-25 y; n = 765 drinking above the low-risk limits (AUDIT-C score >3/4 women/men, but not seeking alcohol treatment, were enrolled from 4 Emergency Departments (EDs in Pittsburgh, PA. Participants were randomized to one of three conditions in a 2:1:1 allocation ratio: SMS Assessments + Feedback (SA+F, SMS Assessments (SA, or control. For 12 weeks, SA+F participants received texts each Thursday querying weekend drinking plans and prompting drinking limit goal commitment and each Sunday querying weekend drinking quantity. SA+F participants received tailored feedback based on their text responses. To contrast the effects of SA+F with self-monitoring, SA participants received texts on Sundays querying drinking quantity, but did not receive alcohol-specific feedback. The control arm received standard care. Follow-up outcome data collected through web-based surveys were provided by 78% of participants at 3- months, 63% at 6-months and 55% at 9-months. Multiple imputation-derived, intent-to-treat models were used for primary analysis. At 9-months, participants in the SA+F group reported greater reductions in the number of binge drinking days than participants in the control group (incident rate ratio [IRR] 0.69; 95% CI .59 to.79, lower binge drinking prevalence (odds ratio [OR] 0.52; 95% CI 0.26 to 0.98], less drinks per drinking day (beta -.62; 95% CI -1.10 to -0.15 and lower alcohol-related injury prevalence (OR 0.42; 95% CI 0.21 to 0.88. Participants in the SA group did not reduce drinking or alcohol-related injury relative to controls. Findings were similar using complete case analyses.An interactive

    Background Cervical cancer poses a significant threat to Korean American women, who are reported to have one of the highest cervical cancer mortality rates in the United States. Studies consistently report that Korean American women have the lowest Pap test screening rates across US ethnic groups. Objective In response to the need to enhance cervical cancer screening in this vulnerable population, we developed and tested a 7-day mobile phone text message-based cervical cancer Screening (mScreening) intervention designed to promote the receipt of Pap tests by young Korean American women. Methods We developed and assessed the acceptability and feasibility of a 1-week mScreening intervention to increase knowledge of cervical cancer screening, intent to receive screening, and the receipt of a Pap test. Fogg’s Behavior Model was the conceptual framework that guided the development of the mScreening intervention. A series of focus groups were conducted to inform the development of the intervention. The messages were individually tailored for each participant and delivered to them for a 7-day period at each participant’s preferred time. A quasi-experimental research design of 30 Korean American women aged 21 to 29 years was utilized with baseline, post (1 week after the completion of mScreening), and follow-up (3 months after the completion of mScreening) testing. Results Findings revealed a significant increase in participants’ knowledge of cervical cancer (Pcancer screening (P=.006). A total of 23% (7/30) (95% CI 9.9-42.3) of the mScreening participants received a Pap test; 83% (25/30) of the participants expressed satisfaction with the intervention and 97% (29/30) reported that they would recommend the program to their friends, indicating excellent acceptability and feasibility of the intervention. Conclusions This study provides evidence of the effectiveness and feasibility of the mScreening intervention. Mobile technology is a promising tool to increase both

    The txt2stop trial has shown that mobile-phone-based smoking cessation support doubles biochemically validated quitting at 6 months. This study examines the cost-effectiveness of smoking cessation support delivered by mobile phone text messaging. The lifetime incremental costs and benefits of adding text-based support to current practice are estimated from a UK NHS perspective using a Markov model. The cost-effectiveness was measured in terms of cost per quitter, cost per life year gained and cost per QALY gained. As in previous studies, smokers are assumed to face a higher risk of experiencing the following five diseases: lung cancer, stroke, myocardial infarction, chronic obstructive pulmonary disease, and coronary heart disease (i.e. the main fatal or disabling, but by no means the only, adverse effects of prolonged smoking). The treatment costs and health state values associated with these diseases were identified from the literature. The analysis was based on the age and gender distribution observed in the txt2stop trial. Effectiveness and cost parameters were varied in deterministic sensitivity analyses, and a probabilistic sensitivity analysis was also performed. The cost of text-based support per 1,000 enrolled smokers is £16,120, which, given an estimated 58 additional quitters at 6 months, equates to £278 per quitter. However, when the future NHS costs saved (as a result of reduced smoking) are included, text-based support would be cost saving. It is estimated that 18 LYs are gained per 1,000 smokers (0.3 LYs per quitter) receiving text-based support, and 29 QALYs are gained (0.5 QALYs per quitter). The deterministic sensitivity analysis indicated that changes in individual model parameters did not alter the conclusion that this is a cost-effective intervention. Similarly, the probabilistic sensitivity analysis indicated a >90 % chance that the intervention will be cost saving. This study shows that under a wide variety of conditions, personalised

    In developed countries, antenatal education aims to reduce difficulties that mothers and fathers experience during transition to parenthood. However, fathers are often distracted from preparing themselves by the attention given to preparing and supporting mothers. Developments in digital communication present alternative means of supporting fathers at this time. Studies, across a range of health concerns, have reported successful outcomes from text-based interventions. Text messaging, focusing on the issues that cause paternal distress at this time, could provide timely, targeted, and effective support to fathers in their transition to parenthood. This study aimed to develop a corpus of messages that could be sent to new fathers during pregnancy and in the months after birth. Messages were intended to support new dads in caring for their own physical and mental health, nurturing strong relationships with their child, and developing strong parenting partnerships. The process employed in message development was similar to that previously employed in developing messages for people who had experienced a cardiac event. A corpus of messages and linked information focusing on fathers' relationships with their children, partners, and themselves were initially developed by a core group. The corpus was then culled, refined, and expanded by a larger, more diverse, group of experts ( n = 46), including parents, academics, and practitioners. The iterative, consultative process used in this study proved to be a functional way of developing and refining a large corpus of timed messages, and linked information, which could be sent to new fathers during their transition to fatherhood.

This qualitative study used focus groups to explore the views and experiences of HIV patients on HAART with adherence reminders, especially the text message (SMS [short message service]. The ethnographic data obtained were used to design a clinical trial to assess the effect of motivational text messages versus usual care to enhance adherence to HAART among HIV patients in Yaoundé, Cameroon. Participants appreciated the idea of a timely SMS reminder, and cited the physician as a role model. They expressed concerns about privacy. Long-term life goals were a motivating factor to adhere. Overall, text messaging was viewed positively as a tool with a dual function of reminder and motivator. Messages coming from the attending physician may have a stronger impact. Trials investigating the use of text messages to improve adherence to HAART need to consider the content and timing of SMS, taking into account technical challenges and privacy.Keywords: focus groups, adherence, highly active antiretroviral therapy (HAART, text message, short message service (SMS, human immunodeficiency virus (HIV

    This study aimed to develop and examine the acceptability, feasibility, and usability of a text messaging, or Short Message Service (SMS), system for improving the receipt of survivorship care for adolescent and young adult (AYA) survivors of childhood cancer. Researchers developed and refined the text messaging system based on qualitative data from AYA survivors in an iterative three-stage process. In stage 1, a focus group (n = 4) addressed acceptability; in stage 2, key informant interviews (n = 10) following a 6-week trial addressed feasibility; and in stage 3, key informant interviews (n = 23) following a 6-week trial addressed usability. Qualitative data were analyzed using a constant comparative analytic approach exploring in-depth themes. The final system includes programmed reminders to schedule and attend late effect screening appointments, tailored suggestions for community resources for cancer survivors, and messages prompting participant feedback regarding the appointments and resources. Participants found the text messaging system an acceptable form of communication, the screening reminders and feedback prompts feasible for improving the receipt of survivorship care, and the tailored suggestions for community resources usable for connecting survivors to relevant services. Participants suggested supplementing survivorship care visits and forming AYA survivor social networks as future implementations for the text messaging system. The text messaging system may assist AYA survivors by coordinating late effect screening appointments, facilitating a partnership with the survivorship care team, and connecting survivors with relevant community resources. The text messaging system has the potential to improve the receipt of survivorship care.

    Smoking is globally the most important preventable cause of ill health and death. Mobile telephone interventions and, in particular, short message service (SMS) text messaging, have the potential to overcome access barriers to traditional health services, not least among young people. To determine the effectiveness of a text-based smoking cessation intervention among young people. A single-blind, 2-arm, randomized clinical trial (Nicotine Exit [NEXit]) was conducted from October 23, 2014, to April 17, 2015; data analysis was performed from April 23, 2014, to May 22, 2015. Participants included daily or weekly smokers willing to set a quit date within 1 month of enrollment. The study used email to invite all college and university students throughout Sweden to participate. The NEXit core program is initiated with a 1- to 4-week motivational phase during which participants can choose to set a stop date. The intervention group then received 157 text messages based on components of effective smoking cessation interventions for 12 weeks. The control group received 1 text every 2 weeks thanking them for participating in the study, with delayed access to the intervention. The primary outcomes were self-reported prolonged abstinence (not having smoked >5 cigarettes over the past 8 weeks) and 4-week point prevalence of complete smoking cessation shortly after the completion of the intervention (approximately 4 months after the quit date). A total of 1590 participants, mainly between 21 and 30 years of age, were randomized into the study; 827 (573 [69.3%] women) were allocated to the intervention group and 763 (522 [68.4%] women) were included in the control group. Primary outcome data were available for 783 (94.7%) of the intervention group and 719 (94.2%) of the control group. At baseline, participants were smoking a median (range) of 63 (1-238) and 70 (2-280) cigarettes per week, respectively. Eight-week prolonged abstinence was reported by 203 participants (25.9%) in the

    It has been suggested that low health literacy (HL) is associated with poor medication adherence. This study aimed to examine the effect of a text message-based HL intervention to promote medication adherence, compared with text messages that only sent medication reminders, in patients with type 2 diabetes. This was a single-center, open-label, randomized (1:1) controlled pilot study. The study period was 6 months. Intervention group was sent HL related text messages, compared to the reminder messages that were sent to the control group. The primary outcome was the difference in the change rate of scores on the Morisky Eight-Item Medication Adherence Scale (MMAS-8). Forty-one participants were randomized into the intervention (n = 21) and control (n = 20) groups and completed the 6-month follow-up. Although almost participants read and understood the information provided in the messages, no significant difference was observed between groups for the primary outcome (p = 0.78). Our results suggested that medication adherence at 6 months after discharge in patients with type 2 diabetes did not significantly change by text messages, which aimed to improve their HL levels.

    Mobile health (mHealth) services cannot easily adapt to users' unique needs. We used simulations of text messaging (SMS) for improving medication adherence to demonstrate benefits of interventions using reinforcement learning (RL). We used Monte Carlo simulations to estimate the relative impact of an intervention using RL to adapt SMS adherence support messages in order to more effectively address each non-adherent patient's adherence barriers, e.g., forgetfulness versus side effect concerns. SMS messages were assumed to improve adherence only when they matched the barriers for that patient. Baseline adherence and the impact of matching messages were estimated from literature review. RL-SMS was compared in common scenarios to simple reminders, random messages, and standard tailoring. RL could produce a 5-14% absolute improvement in adherence compared to current approaches. When adherence barriers are not accurately reported, RL can recognize which barriers are relevant for which patients. When barriers change, RL can adjust message targeting. RL can detect when messages are sent too frequently causing burnout. RL systems could make mHealth services more effective.

    Mobile technology supporting text messaging interventions (TMIs) continues to evolve, presenting challenges for researchers and healthcare professionals who need to choose software solutions to best meet their program needs. The objective of this review was to systematically identify and compare text messaging platforms and to summarize their advantages and disadvantages as described in peer-reviewed literature. A scoping review was conducted using four steps: 1) identify currently available platforms through online searches and in mHealth repositories; 2) expand evaluation criteria of an mHealth mobile messaging toolkit and integrate prior user experiences as researchers; 3) evaluate each platform's functions and features based on the expanded criteria and a vendor survey; and 4) assess the documentation of platform use in the peer-review literature. Platforms meeting inclusion criteria were assessed independently by three reviewers and discussed until consensus was reached. The PRISMA guidelines were followed to report findings. Of the 1041 potentially relevant search results, 27 platforms met inclusion criteria. Most were excluded because they were not platforms (e.g., guides, toolkits, reports, or SMS gateways). Of the 27 platforms, only 12 were identified in existing mHealth repositories, 10 from Google searches, while five were found in both. The expanded evaluation criteria included 22 items. Results indicate no uniform presentation of platform features and functions, often making these difficult to discern. Fourteen of the platforms were reported as open source, 10 focused on health care and 16 were tailored to meet needs of low resource settings (not mutually exclusive). Fifteen platforms had do-it-yourself setup (programming not required) while the remainder required coding/programming skills or setups could be built to specification by the vendor. Frequently described features included data security and access to the platform via cloud-based systems. Pay

    Full Text Available African American adults are less likely to meet the recommended physical activity guidelines for aerobic and muscle-strengthening activity than Caucasian adults. The purpose of this study was to assess whether a text message intervention would increase physical activity in this population. This pilot study used a pre-/post-questionnaire non-randomized design. Participants in a faith-based weight loss competition who agreed to participate in the text messaging were assigned to the intervention group (n = 52. Participants who declined to participate in the intervention, but agreed to participate in the study, were assigned to the control group (n = 30. The text messages provided strategies for increasing physical activity and were based on constructs of the Health Belief Model and the Information-Motivation-Behavioral Skills Model. Chi square tests determined the intervention group participants increased exercise time by approximately eight percent (p = 0.03, while the control group’s exercise time remained constant. The intervention group increased walking and running. The control group increased running. Most participants indicated that the health text messages were effective. The results of this pilot study suggest that text messaging may be an effective method for providing options for motivating individuals to increase physical activity.

    Cell phone-based health information (mobile health or mHealth) campaigns are an emerging technology. This evaluation focused on the aspect of cost of two health information campaigns, one on hypertension and one on pregnancy. Researchers could either contract out the technical components of the campaigns or attempt to run the campaigns themselves, in-house. The in-house campaigns cost an estimated ZAR13 548.72 v. the private provider quotes which ranged from ZAR27 542.97 to ZAR34 227.59. Running the campaigns in-house was more labour intensive and required more technical expertise, but had a reduced delivery failure rate (9.2% in-house v. 30.0% private provider). Running small to medium SMS (text message) campaigns for evaluative purposes proved advantageous over contracting out to private providers. Larger-scale evaluations and full-scale roll-out will require the services of private providers, but it is still essential that researchers actively engage with and monitor the technical aspects of these campaigns.

    Full Text Available Abstract Background Patient-provider communication is a major challenge in resource-limited settings with large catchment areas. Though mobile phone usership increased 20-fold in Africa over the past decade, little is known about acceptability of, perceptions about disclosure and confidentiality, and preferences for cell phone communication of health information in the region. Methods We performed structured interviews of fifty patients at the Immune Suppression Syndrome clinic in Mbarara, Uganda to assess four domains of health-related communication: a cell phone use practices and literacy, b preferences for laboratory results communication, c privacy and confidentiality, and d acceptability of and preferences for text messaging to notify patients of abnormal test results. Results Participants had a median of 38 years, were 56% female, and were residents of a large catchment area throughout southwestern Uganda. All participants expressed interest in a service to receive information about laboratory results by cell phone text message, stating benefits of increased awareness of their health and decreased transportation costs. Ninety percent reported that they would not be concerned for unintended disclosure. A minority additionally expressed concerns about difficulty interpreting messages, discouragement upon learning bad news, and technical issues. Though all respondents expressed interest in password protection of messages, there was also a strong desire for direct messages to limit misinterpretation of information. Conclusions Cell phone text messaging for communication of abnormal laboratory results is highly acceptable in this cohort of HIV-infected patients in rural Uganda. The feasibility of text messaging, including an optimal balance between privacy and comprehension, should be further studied.

    The aim of this study is to test the acceptance and efficacy of an individualised text messaging (SMS)-based intervention to support smoking cessation in apprentices of vocational schools. The SMS program MyWay, which generated individualised text messages to support smoking cessation based on an online assessment and a weekly SMS assessment, was developed. The text messages were based on the Transtheoretical Model of Behavior Change and sent to the programme participants over a period of 3 months. The programme was tested in 62 school classes at 6 vocational schools in Bremen, Germany, where 1 086 apprentices participated in an online assessment addressing demographic and smoking related variables. A total of 415 persons (38%) fulfilled the inclusion criteria "daily cigarette smoking", "ownership of a cell phone" and "regular use of text messaging". Of these, 210 persons (51%) participated in the programme. A 6-month follow-up telephone interview for the evaluation of the SMS programme and the assessment of smoking-related variables could be conducted in 125 (60%) of the 210 programme participants. Compared to the baseline assessment, the smoking prevalence (7-day-point prevalence abstinence, 11%) and the intention to stop smoking (psmoked at this point in time (psmoking cessation services, this intervention approach allows us to reach a substantial part of smokers in vocational schools.

    Depression and Alcohol Use Disorders (AUDs) are two leading causes of disability worldwide and are associated with significant treatment challenges requiring new, innovative, cost-effective and technologically-based therapies including the use of supportive text messages. To determine the feasibility and effectiveness of supportive text messages in long-term follow-up to reduce mood symptoms and problem drinking in patients with Depression or AUD respectively and to explore the usefulness of self-reports of health services utilization as an outcomes measure. This will be a longitudinal, prospective, parallel-design, two-arm, placebo-controlled single-rater-blinded randomized clinical trial with a recruitment period of 6 months and an observation period of 12 months for each participant, with two strata based on primary diagnosis of Major Depressive Disorder or AUD. The sample size will be 120, with about 60 patients randomized from each primary diagnostic grouping. Patients in all intervention groups will receive twice-daily supportive SMS text messages for 3 months and then daily supportive text messages for the next three months. Patients will also receive a phone call every two weeks from the research assistant assigning treatment allocation to confirm that they are still receiving the text messages and to thank them for taking part in the study. Patients in the control group will receive no text messages but will also receive a phone call from the same research assistant every two weeks to thank them for taking part in the study. The study starts in April 2015 and ends in September 2016. It is envisaged that both qualitative and quantitative primary and secondary outcomes, including patient perceptions of the intervention, will shed light on the feasibility of using automated supportive text message interventions in long term for patients with Depression and AUD. This will inform a full-scale clinical trial. The paradigm for behavior change using text messages

    Black men who have sex with men (MSM) are disproportionately infected with HIV and are less well retained along the HIV continuum of care. We report on the feasibility of a peer support text messaging intervention designed to increase retention in HIV care and HIV medication adherence among HIV-infected black men who have sex with men. Based on formative research, a cell phone app was developed to support a peer-based text messaging intervention. The app allowed the researchers to view text messages sent between mentors and mentees, but did not allow them to view other text messages sent by these phones. Three HIV-infected black men who have sex with men were recruited to serve as volunteer peer mentors. They were trained in motivational techniques, peer support skills, and skills for improving appointment attendance and medication adherence. Mentees (N = 8) received the intervention for 1 month. Mentees completed a postintervention survey and interview. The peer mentor text messaging intervention was feasible. Mentors delivered support in a nonjudgmental, motivational way. However, technical and other implementation problems arose. Some mentees desired more frequent contact with mentors, and mentors reported that other commitments made it difficult at times to be fully engaged. Both mentors and mentees desired more personalized contact (ie, phone calls). A text messaging peer mentor intervention was feasible. Additional research with a larger sample is needed to determine optimal ways to improve mentors' engagement in the intervention and to determine intervention acceptability and efficacy. In future studies, peer support phone calls could be incorporated.

    This study examines factors associated with the acceptability of receiving sexually transmitted disease (STD) laboratory results by text message and e-mail among clinic attendees. An anonymous self-administered survey was conducted with a convenience sample of STD clinic attendees in South Carolina and Mississippi in 2009-2010. In total, 2,719 individuals with a median age of 26 years (interquartile range, 21-32 years) completed the survey. More than 70% had Internet access at home, and 80% reported using text messaging daily. Participants preferred receiving laboratory results by text message compared with e-mail (50.2% versus 42.3%; p<0.001). Acceptability of receiving laboratory results by text message was higher with younger age (adjusted odds ratio [aOR] 1.13; 95% confidence interval [CI] 1.10-1.26), daily use of text messaging (aOR 1.30; 95% CI 1.14-1.49), and reporting cell phone and text message as the preferred choice of regular communication with the clinic (aOR 2.31; 95% CI 1.50-3.58) and was significantly lower in female subjects (aOR 0.89; 95% CI 0.81-0.98) and those with college-level education (aOR 0.88; 95% CI 0.77-0.99). A majority of STD clinic attendees have access to cell phones and Internet. The acceptability of receiving STD laboratory results electronically may facilitate test result delivery to patients and expedite treatment of infected individuals.

    Simple interventions for improving health workers' adherence to malaria case-management guidelines are urgently required across Africa. A recent trial in Kenya showed that text-message reminders sent to health workers' mobile phones improved management of pediatric outpatients by 25 percentage points. In this paper we examine costs and cost-effectiveness of this intervention. We evaluate costs and cost-effectiveness in 2010 USD under three implementation scenarios: (1) as implemented under study conditions in study areas; (2) if the intervention was routinely implemented by the Ministry of Health (MoH) in the same areas; and (3) if the intervention was scaled up nationally. Under study conditions, intervention costs were 19,342 USD, of which 45% were for developing and pretesting text-messages, 12% for developing text-message distribution system, 29% for collecting health workers' phone numbers, and 13% were costs of sending text-messages and monitoring of the system. If the intervention was implemented in the same areas by the MoH, the costs would be 28% lower (13,920 USD) due to lower costs of collecting health workers' numbers. The cost of national scale-up would be 97,350 USD, and the majority of these costs (66%) would be for sending text-messages. The cost per additional child correctly managed was 0.50 USD under study conditions, 0.36 USD if implemented by the MoH in the same area, and estimated at only 0.03 USD if implemented nationally. Even if the effect size was only 5% or the cost on the national scale was 400% higher than estimated, the cost per additional child correctly managed would be only 0.16 USD. A simple text-messaging intervention improving health worker adherence to malaria guidelines is effective and inexpensive. Further research is justified to optimize delivery of the intervention and expand targets beyond children and malaria disease.

    The objective of this paper is to characterize effective patient care reminder strategies for people living with HIV/AIDS (PLWHA) to improve antiretroviral therapy (ART) adherence) using short message service (SMS) based on patient perspectives. We conducted a qualitative study with adult PLWHA in a community-based clinic in Lima, Peru using focus groups. 26 HIV-positive individuals participated in four focus groups (20 men, 6 women). The participants expressed positive perceptions towards receiving reminders via SMS, but specified certain characteristics they wanted them to have (such as being simple and concise). It was also important that the messages maintained confidentiality and privacy by using coded words or phrases (“Remember, it is the time of your life”) instead of “sensitive” words (HIV or antiretroviral). This study suggests that patients want healthcare SMS that appropriately notify them, deliver a careful crafted message, and assess the context in which they are received. PMID:21633523

  18. More Than a Text Message: Dismantling Digital Triggers to Curate Behavior Change in Patient-Centered Health Interventions.

    Digital triggers such as text messages, emails, and push alerts are designed to focus an individual on a desired goal by prompting an internal or external reaction at the appropriate time. Triggers therefore have an essential role in engaging individuals with digital interventions delivered outside of traditional health care settings, where other events in daily lives and fluctuating motivation to engage in effortful behavior exist. There is an emerging body of literature examining the use of digital triggers for short-term action and longer-term behavior change. However, little attention has been given to understanding the components of digital triggers. Using tailoring as an overarching framework, we separated digital triggers into 5 primary components: (1) who (sender), (2) how (stimulus type, delivery medium, heterogeneity), (3) when (delivered), (4) how much (frequency, intensity), and (5) what (trigger's target, trigger's structure, trigger's narrative). We highlighted key considerations when tailoring each component and the pitfalls of ignoring common mistakes, such as alert fatigue and habituation. As evidenced throughout the paper, there is a broad literature base from which to draw when tailoring triggers to curate behavior change in health interventions. More research is needed, however, to examine differences in efficacy based on component tailoring, to best use triggers to facilitate behavior change over time, and to keep individuals engaged in physical and mental health behavior change efforts. Dismantling digital triggers into their component parts and reassembling them according to the gestalt of one's change goals is the first step in this development work. ©Frederick Muench, Amit Baumel.

    SMS text messaging is increasingly used for delivering smoking cessation support and pilot studies suggest this may also be useful in pregnancy. This study explores the views of women who received a tailored text messaging cessation intervention (MiQuit) during pregnancy, focusing on acceptability, perceived impact, and suggestions for improvements. Semi-structured interviews were undertaken with 15 purposively sampled women who had received the MiQuit intervention during pregnancy as part of a randomized controlled trial. Data were analyzed thematically. Three main themes were identified: "impact", "approach," and "optimization." Participants described an immediate, yet often short-lived, impact from the texts that distracted and delayed them from smoking and they perceived that texts focusing on the development of and risk to the baby generated more enduring emotional impacts. Most women found receiving support by text preferable to face-to-face cessation support, with participants citing the greater regularity, convenience, and non-judgmental style as particular advantages. Participants would have preferred a longer support program with increased tailoring, greater customization of text timings and consideration of cutting down as an alternative/precursor to quitting. Pregnancy-specific cessation support by text message was well received and participants considered the support increased their motivation to stop smoking. The focus on the developing baby, the regularity of contact and the provision of gentle, encouraging messages were highlighted as particularly important elements of the program. This study adds further evidence to the acceptability and perceived positive impact of text-messaging programs in aiding smoking cessation in pregnancy. The findings indicate that for some women, this type of support is preferable to face-to-face methods and could be utilized by health professionals, either in addition to current methods or as an alternative.

    Ecological momentary assessments (EMA) are data collection approaches that characterize behaviors in real-time. However, EMA is underutilized in alcohol and substance use research among men who have sex with men (MSM). The aim of this analysis is to explore the correlates of engagement in EMA text messages among substance-using MSM in San Francisco. The present analysis uses data collected from the Project iN pilot study (n=30). Over a two-month period, participants received and responded to EMA daily text messages inquiring about their study medication, alcohol, and methamphetamine use. Baseline characteristics including demographics, alcohol use, and substance use were examined as potential correlates of engagement in EMA text messages in logistic regression and proportional hazards models. Participants had a 74% response rate to EMA text messages over the study period. MSM of color had significantly lower adjusted odds of responding to EMA texts 80% of the time or more, compared to white MSM (adjusted odds ratio=0.05, 95%CI=0.01-0.38). College-educated MSM had a lower adjusted hazard of week-long discontinuation in EMA texts (adjusted hazard ratio=0.12, 95%CI=0.02-0.63). Older MSM had a higher adjusted hazard of week-long discontinuation in EMA texts (adjusted hazard ratio=1.15, 95%CI=1.01-1.31). Differences in engagement in EMA text prompts were discovered for MSM with different racial/ethnic backgrounds, ages, and education levels. Substance use variables were not correlated with engagement in text messages, suggesting that EMA may be a useful research tool among actively substance-using MSM in San Francisco.

    OBJECTIVE To engage a group of people with relevant lived experience in the development of a text-messaging intervention to reduce repetition of self-harm. BACKGROUND Contact-based interventions, such as follow-up letters, postcards and telephone calls, have shown potential to reduce repetition of self-harm in those who present at Accident and Emergency departments. Text messaging offers a low-cost alternative that has not been tested. We set out to develop a text-based intervention. The process of intervention development is rarely reported and little is known about the impact of service user involvement on intervention design. METHOD We held a series of six participatory workshops and invited service users and clinicians to help us work out how to get the right message to the right person at the right time, and to simulate and test prototypes of an intervention. RESULTS Service users rejected both the idea of a generic, 'one size fits all' approach and that of 'audience segmentation', maintaining that text messages could be safe and effective only if individualized. This led us to abandon our original thinking and develop a way of supporting individuals to author their own self-efficacy messages and store them in a personal message bank for withdrawal at times of crisis. CONCLUSIONS This paper highlights both the challenge and the impact of involving consumers at the development stage. Working with those with lived experience requires openness, flexibility and a readiness to abandon or radically revise initial plans, and may have unexpected consequences for intervention design. © 2010 Blackwell Publishing Ltd.

  2. Experiences of Older Adults With Mobile Phone Text Messaging as Reminders of Home Exercises After Specialized Manual Therapy for Recurrent Low Back Pain: A Qualitative Study

    Science.gov (United States)

    2017-01-01

    Background Clinical experience of manual therapy for musculoskeletal pain is that patients often suffer from recurrent pain and disorders, but that they do not continue to perform their physical home exercises when they are free from symptoms. The chance of positive long-term effects of manual therapy would probably increase if patients were reminded that they are to continue to perform their exercises. Mobile phone text messaging (short messaging service, SMS) is increasingly used as an innovative intervention to remind patient to exercise. However, there are only a few studies on such interventions in the field of low back pain (LBP). Qualitative studies of patients’ experiences of receiving text messages as reminders of home exercises after manual treatment for recurrent LBP have to the best of our knowledge never been published. Objectives The aim of this study was to explore older persons’ common experiences of receiving reminders of home exercises through mobile phone text messaging after specialized manual therapy for recurrent LBP. Methods A total of 7 men and 8 women (67-86 years), who had sought specialized manual therapy (Naprapathic manual therapy) for recurrent LBP were included in the study. Individual one-way text messages as reminders of home exercises (to be performed on a daily basis) were sent to each patient every third day for 3 weeks, then once a week for another 2 weeks. Semistructured interviews with 2 broad, open-ended questions were held and data were analyzed with systematic text condensation, based on Giorgi’s principles of psychological phenomenological analysis. Results The participants appreciated the messages, which were perceived as timely and usable, and also stimulated memorizing. The messages made the participants reflect on the aim of the exercise, value of being reminded, and on their improvement in pain. During the interviews, the participants created their own routines for continued adherence to the exercises

    Significant gaps exist in the published literature regarding the treatment of overweight/obesity in preschool-aged children, especially in primary care settings. Parental influence plays an important factor in the development of healthy behaviors in children, yet there is no consensus about why some behavior change intervention strategies for parents of young children are more influential and effective than others. The purpose of this secondary data analysis was to assess correlations among the study variables (healthy lifestyle beliefs, perceived difficulty, and healthy lifestyle behaviors) in parents of overweight/obese preschool children. A second aim explored if the parent's level of cognitive beliefs and perceived difficulty of engaging in healthy lifestyle behaviors correlated with text messaging cognitive behavioral support. Fifteen preschool-parent dyads from primary care clinics completed a 7-week cognitive behavioral skills building intervention. Beck's Cognitive Theory guided the intervention content, and Fogg's Behavior Model guided the implementation. The intervention was delivered using a combination of face-to-face clinic visits and ecological momentary interventions using text messaging. Supported are the interconnected relationships among the study variables, that is, parental healthy lifestyle beliefs, thoughts, and behaviors. At baseline, parental healthy lifestyle belief scores significantly correlated with perceived difficulty (rs = 0.598, p behaviors (rs = 0.545, p cognitive behavioral skills building and tailored text messaging, the need for general support via text messaging lessened, warranting additional research.

    Mobile phone text messaging has been shown to improve adherence to antiretroviral therapy and to improve communication between patients and health care workers. It is unclear which strategies are most appropriate for scaling up text messaging programmes. We sought to investigate acceptability and readiness for ownership (community members designing, sending and receiving text messages) of a text message programme among a community of clients living with human immunodeficiency virus (HIV) in Yaoundé, Cameroon and to develop a framework for implementation. We used the mixed-methods sequential exploratory design. In the qualitative strand we conducted 7 focus group discussions (57 participants) to elicit themes related to acceptability and readiness. In the quantitative strand we explored the generalizability of these themes in a survey of 420 clients. Qualitative and quantitative data were merged to generate meta-inferences. Both qualitative and quantitative strands showed high levels of acceptability and readiness despite low rates of participation in other community-led projects. In the qualitative strand, compared to the quantitative strand, more potential service users were willing to pay for a text messaging service, preferred participation of health personnel in managing the project and preferred that the project be based in the hospital rather than in the community. Some of the limitations identified to implementing a community-owned project were lack of management skills in the community, financial, technical and literacy challenges. Participants who were willing to pay were more likely to find the project acceptable and expressed positive feelings about community readiness to own a text messaging project. Community ownership of a text messaging programme is acceptable to the community of clients at the Yaoundé Central Hospital. Our framework for implementation includes components for community members who take on roles as services users (demonstrating

    evidence-based text message created by researchers and the message received by the recipient in mobile health interventions. These discrepancies were primarily generated by six mediators of meaning in SMS messages: (1) negative or non-affirming framing of advocacies, (2) fear- or stress-inducing content, (3) oppressive or authoritarian content, (4) incongruity with cultural and traditional practices, (5) disconnect with the reality of the social determinants of health and the diversity of cultures within a population, and (6) lack of clarity and/or practicality of content. These 6 mediators of meaning provide the basis for sound strategies for message development because they impact directly on the target populations' capability, opportunity, and motivation for behavior change. The quality of text messages impacts significantly on the effectiveness of a mobile health intervention. Our research underscores the urgent need for interventions to incorporate and evaluate the quality of SMS messages and to examine the mediators of meaning within each targeted cultural and demographic group. Reporting on this aspect of mobile health intervention research will allow researchers to move away from the current black box of SMS text message development, thus improving the transparency of the process as well as the quality of the outcomes.

    2017-01-01

    Qualitative and quantitative research was used to create the Uses of Texting in Sexual Relationships scale. At-risk, predominantly African American emerging adults participated in qualitative interviews (N = 20) and quantitative surveys (N = 110) about their uses of text messaging within romantic and sexual relationships. Exploratory factor analysis of items generated from interviews resulted in four subscales: Sexting, Relationship Maintenance, Relationship Development, and Texting for Sexual Safety. Exploratory analyses indicated associations of Sexting with more instances of condomless sex, and Texting for Sexual Safety with fewer instances of condomless sex, which was moderated by relationship power. Further research on the connections between text messaging in relationships and sexual behavior among high-risk and minority young adults is warranted, and intervention efforts to decrease sexual risks need to incorporate these avenues of sexual communication.

    Physicians' daily work is increasingly affected by the use of emails, text messages and cell phone calls with their patients. The aim of this study was to describe their use between primary-care physicians and patients in a French-speaking part of Switzerland. A cross-sectional mail survey was conducted among all primary-care physicians of Geneva canton (n = 636). The questionnaire focused on the frequency of giving access to, type of use, advantages and disadvantages of email, cell phone calls and text messages communication between physicians and patients. Six hundred thirty-six questionnaires were mailed, 412 (65 %) were returned and 372 (58 %) could be analysed (37 refusals and three blanks). Seventy-two percent physicians gave their email-address and 74 % their cell phone number to their patients. Emails were used to respond to patients' questions (82 %) and change appointments (72 %) while cell phone calls and text messages were used to follow patients' health conditions. Sixty-four percent of those who used email communication never discussed the rules for email exchanges, and 54 % did not address confidentiality issues with their patients. Most commonly identified advantages of emails, cell phone calls and text messages were improved relationship with the patient, saving time (for emails) and improving the follow-up (for cell phone and text messages). The main disadvantages included misuse by the patient, interference with private life and lack of reimbursement. These tools are widely used by primary-care physicians with their patients. More attention should be paid to confidentiality, documentation and reimbursement when using email communication in order to optimize its use.

    Low-income, racial/ethnic minorities are often nonadherent to diabetes medications, have uncontrolled glycemia, and have high rates of diabetes-related morbidity. Cell phones provide a viable modality to support medication adherence, but few cell phone-based interventions have been designed for low-income persons, a population with more feature phone penetration than smartphone penetration. In an effort to reach the broadest range of patients, we leveraged the voice and text messaging capabilities shared by all cell phones to design the MEssaging for Diabetes intervention. We specifically advanced and adapted an existing tailored text messaging system to include interactive voice response functionality and support the medication adherence barriers of low-income, diverse adults with type 2 diabetes mellitus. We report on the design process and feasibility testing results (i.e., technical use patterns and subjective user experiences) from patients from the target population who used the intervention in one of three user-centered design iterations. The types of challenges encountered in design were related to providing text message content with valued information and support that engages patients. The design process also highlighted the value of obtaining mixed methods data to provide insight into legitimate versus illegitimate missing data, patterns of use, and subjective user experiences. The iterative testing process and results outlined here provide a potential template for other teams seeking to design technology-based self-care support solutions for comparable patient populations.

    Background Poor communications between cystic fibrosis (CF) patients and health-care providers may result in gaps in knowledge and misconceptions about medication usage, and can lead to poor adherence. We aimed to assess the feasibility of using WhatsApp and Skype to improve communications. Methods This single-centre pilot study included CF patients who were older than eight years of age assigned to two groups: one without intervention (control group), and one with intervention. Each patient from the intervention group received Skype-based online video chats and WhatsApp messages from members of the multidisciplinary CF team. CF questionnaires, revised (CFQ-R) scores, knowledge and adherence based on CF My Way and patients satisfaction were evaluated before and after three months. Feasibility was assessed by session attendance, acceptability and satisfaction survey. Descriptive analysis and paired and non-paired t-tests were used as applicable. Results Eighteen patients were recruited to this feasibility study (nine in each group). Each intervention group participant had between four and six Skype video chats and received 22-45 WhatsApp messages. In this small study, CFQ-R scores, knowledge, adherence and patient satisfaction were similar in both groups before and after the three-month intervention. Conclusions A telehealth-based approach, using Skype video chats and WhatsApp messages, was feasible and acceptable in this pilot study. A larger and longer multi-centre study is warranted to examine the efficacy of these interventions to improve knowledge, adherence and communication.

  16. Costs and cost-effectiveness of a mobile phone text-message reminder programmes to improve health workers' adherence to malaria guidelines in Kenya.

    Dejan Zurovac

    Full Text Available BACKGROUND: Simple interventions for improving health workers' adherence to malaria case-management guidelines are urgently required across Africa. A recent trial in Kenya showed that text-message reminders sent to health workers' mobile phones improved management of pediatric outpatients by 25 percentage points. In this paper we examine costs and cost-effectiveness of this intervention. METHODS/FINDINGS: We evaluate costs and cost-effectiveness in 2010 USD under three implementation scenarios: (1 as implemented under study conditions in study areas; (2 if the intervention was routinely implemented by the Ministry of Health (MoH in the same areas; and (3 if the intervention was scaled up nationally. Under study conditions, intervention costs were 19,342 USD, of which 45% were for developing and pretesting text-messages, 12% for developing text-message distribution system, 29% for collecting health workers' phone numbers, and 13% were costs of sending text-messages and monitoring of the system. If the intervention was implemented in the same areas by the MoH, the costs would be 28% lower (13,920 USD due to lower costs of collecting health workers' numbers. The cost of national scale-up would be 97,350 USD, and the majority of these costs (66% would be for sending text-messages. The cost per additional child correctly managed was 0.50 USD under study conditions, 0.36 USD if implemented by the MoH in the same area, and estimated at only 0.03 USD if implemented nationally. Even if the effect size was only 5% or the cost on the national scale was 400% higher than estimated, the cost per additional child correctly managed would be only 0.16 USD. CONCLUSIONS: A simple text-messaging intervention improving health worker adherence to malaria guidelines is effective and inexpensive. Further research is justified to optimize delivery of the intervention and expand targets beyond children and malaria disease.

    The college experience is often the first time when young adults live independently and make their own lifestyle choices. These choices affect dietary behaviors, exercise habits, techniques to deal with stress, and decisions on sleep time, all of which direct the trajectory of future health. There is a need for effective strategies that will encourage healthy lifestyle choices in young adults attending college. This preliminary randomized controlled trial tested the effect of coaching and text messages (short message service, SMS) on self-selected health behaviors in the domains of diet, exercise, stress, and sleep. A second analysis measured the ripple effect of the intervention on health behaviors not specifically selected as a goal by participants. Full-time students aged 18-30 years were recruited by word of mouth and campuswide advertisements (flyers, posters, mailings, university website) at a small university in western Pennsylvania from January to May 2015. Exclusions included pregnancy, eating disorders, chronic medical diagnoses, and prescription medications other than birth control. Of 60 participants, 30 were randomized to receive a single face-to-face meeting with a health coach to review results of behavioral questionnaires and to set a health behavior goal for the 8-week study period. The face-to-face meeting was followed by SMS text messages designed to encourage achievement of the behavioral goal. A total of 30 control subjects underwent the same health and behavioral assessments at intake and program end but did not receive coaching or SMS text messages. The texting app showed that 87.31% (2187/2505) of messages were viewed by intervention participants. Furthermore, 28 of the 30 intervention participants and all 30 control participants provided outcome data. Among intervention participants, 22 of 30 (73%) showed improvement in health behavior goal attainment, with the whole group (n=30) showing a mean improvement of 88% (95% CI 39-136). Mean

    Breast cancer is now the leading cause of death in Hispanic women (HW). Internet, e-mail, and instant text messaging may be cost-effective in educating HW about breast health and in reducing breast cancer mortality. We surveyed 905 HW women attending a free health fair about their technology use, acculturation, insurance status, mammography use, and breast cancer knowledge. Data were analyzed by t test or χ(2) tests. Mean age was 51.9 ± 14.2 years (range, 18 to 88 years). Ninety-two per cent were foreign-born. Most had completed some high school (39%) or elementary (38%) education. Most (62%) were uninsured. The majority spoke (67%) and read (66%) only Spanish. Only 60 per cent of HW older than 40 years had a recent mammogram. HW older than 40 years who had not had a recent mammogram were younger (mean 54.9 ± 10.8 vs 58 ± 10.4 years) and less likely to have health insurance (25 vs 44%; P e-mail (64%). However, 70 per cent have mobile phones (66% older than 40 years), and 65 per cent use text messaging daily (58% older than 40 years, P = 0.001). In fact, 45 per cent wish to receive a mammogram reminder by text. Text messaging may be an inexpensive way to promote breast health and screening mammography use among uninsured HW.

    ABSTRACT: INTRODUCTION: The use of automated text messages has made it possible to identify different courses of low back pain (LBP), and it has been observed that pain often fluctuates and that absolute recovery is rather rare. The purpose of this study was to describe the prevalence of pain...... treated by chiropractors for non-specific LBP. Over 18 weeks, subjects answered a weekly automated text message question on the number of days in the past week that they had experienced bothersome LBP, i.e. a number between 0 and 7. The number of weeks in a row without any LBP at all ("zero weeks......") as well as the maximum number of zero weeks in a row was determined for each individual. Comparisons were made between the two study samples. Estimates are presented as percentages with 95% confidence intervals. RESULTS: In the Danish and the Swedish populations respectively, 93/110 (85%) and 233/262 (89...

    Objective: We sought to identify patterns of response (latent classes) to a text-message (short message service) intervention based on weekend drinking cognitions (e.g., drinking plans, commitment to a low consumption goal), and to examine how the latent classes differed in baseline characteristics and alcohol consumption outcomes. Method: We conducted a secondary analysis of 384 non–treatment seeking young adults with hazardous alcohol use randomly assigned to a 12-week short message service intervention. Responses to weekly short message service queries related to weekend drinking cognitions were categorized as (a) planned not to drink, (b) planned to drink but did not plan a heavy drinking episode (HDE), (c) planned to have an HDE but willing to limit alcohol consumption, (d) planned to have an HDE and not willing to limit alcohol consumption We used repeated-measures latent class analysis to identify distinct classes based on these categories and examined associations of the classes with baseline covariates and alcohol consumption outcomes through 6 months. Results: We identified the following three latent classes: planned not to drink (62%), willing to limit drinks (27%), and not willing to limit drinks (12%). The “not willing to limit drinks” class exhibited the least reductions in alcohol consumption and was more likely to include White individuals and those with higher baseline drinking severity. The “planned not to drink” class had the greatest reductions in alcohol consumption. Conclusions: Young adults who exhibited low likelihood of committing to goals to limit weekend drinking were less responsive to short message service intervention, suggesting the need for alternative interventions.

    Full Text Available Following male circumcision for HIV prevention, a high proportion of men fail to return for their scheduled seven-day post-operative visit. We evaluated the effect of short message service (SMS text messages on attendance at this important visit.We enrolled 1200 participants >18 years old in a two-arm, parallel, randomized controlled trial at 12 sites in Nyanza province, Kenya. Participants received daily SMS text messages for seven days (n = 600 or usual care (n = 600. The primary outcome was attendance at the scheduled seven-day post-operative visit. The primary analysis was by intention-to-treat.Of participants receiving SMS, 387/592 (65.4% returned, compared to 356/596 (59.7% in the control group (relative risk [RR] = 1.09, 95% confidence interval [CI] 1.00-1.20; p = 0.04. Men who paid more than US$1.25 to travel to clinic were at higher risk for failure to return compared to those who spent ≤ US$1.25 (adjusted relative risk [aRR] 1.35, 95% CI 1.15-1.58; p<0.001. Men with secondary or higher education had a lower risk of failure to return compared to those with primary or less education (aRR 0.87, 95% CI 0.74-1.01; p = 0.07.Text messaging resulted in a modest improvement in attendance at the 7-day post-operative clinic visit following adult male circumcision.

    Despite the increased use of social media and text messaging among adolescents, it is unclear how effective education transmitted via these mechanisms is for reducing sexual risk behavior. Accordingly, we conducted a systematic review of the literature to examine the effectiveness of social media and text messaging interventions designed to increase sexually transmitted disease (STD) knowledge, increase screening/testing, decrease risky sexual behaviors, and reduce the incidence of STDs among young adults aged 15 through 24 years. Eleven studies met our inclusion criteria. Most of the included studies used a control group to explore intervention effects and included both young men and women. Sample sizes ranged from 32 to 7606 participants, and follow-up periods ranged between 4 weeks and 12 months. These studies provide preliminary evidence indicating that social media and text messaging can increase knowledge regarding the prevention of STDs. These interventions may also affect behavior, such as screening/testing for STDs, sexual risk behaviors, and STD acquisition, but the evidence for effect is weak. Many of these studies had several limitations that future research should address, including a reliance on self-reported data, small sample sizes, poor retention, low generalizability, and low analytic rigor. Additional research is needed to determine the most effective and engaging approaches for young men and women.

    Artemisinin combination therapies are available in private outlets, but patient adherence might be compromised by poor advice from dispensers. In this cluster randomized trial in drug shops in Tanzania, 42 of 82 selected shops were randomized to receive text message reminders about what advice to provide when dispensing artemether-lumefantrine (AL). Eligible patients purchasing AL at shops in both arms were followed up at home and questioned about each dose taken. Dispensers were interviewed regarding knowledge of AL dispensing practices and receipt of the malaria-related text messages. We interviewed 904 patients and 110 dispensers from 77 shops. Although there was some improvement in dispenser knowledge, there was no difference between arms in adherence measured as completion of all doses (intervention 68.3%, control 69.8%, p [adjusted] = 0.6), or as completion of each dose at the correct time (intervention 33.1%, control 32.6%, p [adjusted] = 0.9). Further studies on the potential of text messages to improve adherence are needed. © The American Society of Tropical Medicine and Hygiene.

    For youth living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), nonadherence to antiretroviral therapy (ART) can lead to poor health outcomes and significantly decreased life expectancy. To evaluate the feasability, acceptability, and preliminary efficacy of short message service (SMS) or text message reminders to improve adherence to ART for youth living with HIV/AIDS. We conducted this prospective pilot study using a pre-post design from 2009 to 2010 at a community-based health center providing clinical services to youth living with HIV/AIDS. Eligibility criteria included HIV-positive serostatus, age 14-29 years, use of a personal cell phone, English-speaking, and being on ART with documented poor adherence. During the 24-week study period, participants received personalized daily SMS reminders and a follow-up message 1 hour later assessing whether they took the medication, and asking participants to respond via text message with the number 1 if they took the medication and 2 if they did not. Outcome measures were feasibility, acceptability, and adherence. Self-reported adherence was determined using the visual analog scale (VAS) and AIDS Clinical Trial Group (ACTG) questionnaire 4-day recall. Viral load and CD4 cell count were followed as biomarkers of adherence and disease progression at 0, 12, and 24 weeks. Participants (N = 25) were mean age 23 (range 14-29) years, 92% (n = 23) male, 60% (n = 15) black, and 84% (n = 21) infected through unprotected sex. Mean VAS scores significantly increased at 12 and 24 weeks in comparison with baseline (week 0: 74.7, week 12: 93.3, P AIDS.

    A randomized controlled trial was conducted in 2015 to evaluate a mobile continuing medical education (mCME) intervention that provided daily text messages to community-based physicians' assistants (CBPAs) in Thai Nguyen Province, Vietnam. Although the intervention failed to improve medical knowledge over a 6-month period, a companion qualitative study provided insights on the views and experiences of intervention participants. We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) among participants randomized to receive text messages containing either simple medical facts or quiz questions. Trained interviewers collected data immediately following the conclusion of the trial in December 2015. Using semi-structured question guides, respondents were queried on their views of the intervention, positive and negative, and perceived impacts of the intervention. During analysis, after learning that the intervention had failed to increase knowledge among participants, we also examined reasons for lack of improvement in medical knowledge. All analyses were performed in NVivo using a thematic approach. A total of 70 CBPAs engaged in one of 8 FGDs or an IDI. One-half were men; average age among all respondents was 40 years. Most (81%) practiced in rural settings and most (51%) focused on general medicine. The mean length of work experience was 3 years. All respondents made positive comments about the intervention; convenience, relevance, and quick feedback (quiz format) were praised. Downsides encompassed lack of depth of information, weak interaction, technology challenges, and challenging/irrelevant messages. Respondents described perceived impacts encompassing increased motivation, knowledge, collegial discussions, Internet use to search for more information, and clinical skills. Overall, they expressed a desire for the intervention to continue and recommended expansion to other medical professionals. Overreliance on the text messages, lack of

    To improve the knowledge and skills of diabetic patients on insulin injections using mobile phone short message services and to evaluate the association of this intervention with metabolic outcomes. Mobile communication technologies are widely used in Turkey, which maintains a diabetic population of more than 6·5 million. However, there are a limited number of studies using mobile technologies in the challenging and complicated management of diabetes. A one group pretest-posttest design was used in this study. The study sample consisted of 221 people with type 1 and type 2 Diabetes Mellitus from eight outpatient clinics in six cities in Turkey. The 'Demographic and diabetes-related information Form' and 'Insulin Injection Technique and Knowledge Form' were used in the initial interview. Subsequently, 12 short messages related to insulin administration were sent to patients twice a week for six months. Each patient's level of knowledge and skills regarding both the insulin injection technique and glycaemic control (glycated haemoglobin A1c) levels were measured at three months and six months during the text messaging period and six months later (12 months total) when text messaging was stopped. The mean age of the patients with diabetes was 39·8 ± 16·2 years (min: 18; max: 75). More than half of the patients were females with a mean duration of diabetes of 11·01 ± 7·22 years (min 1; max: 32). Following the text message reminders, the patients' level of knowledge and skills regarding the insulin injection technique improved at month 3 and 6 (p levels statistically significantly decreased at the end of month 3, 6 and 12 compared to the baseline values (p diabetes by nurses resulted in improved self-administration of insulin and metabolic control.

    Background Obesity, deconditioning, cognitive impairment, and poor exercise tolerance are health issues concerning adults with spina bifida (SB). Our aim is to describe exercise participation and identify motivating tactics and exercise devices that increase participation. Design In a quasi-experimental randomized crossover design, the GameCycle was compared to a Saratoga Silver I arm ergometer. Personalized free or low cost text/voice message reminders to exercise were sent. Methods Nineteen young adults with SB were assigned to either the GameCycle or Saratoga exercise group. Within each group, participants were randomized to receive reminders to exercise, or no reminders, then crossed over to the opposite message group after eight weeks. Before and after a 16 week exercise program we collected anthropometric, metabolic, exercise testing and questionnaire data, and recorded participation. Results Miles traveled by the GameCycle group were significantly higher than the Saratoga exercise groups. No significant differences were found in participation between the message reminder groups. Low participation rates were seen overall. Conclusions Those using the GameCycle traveled more miles. Barriers to exercise participation may have superseded ability to motivate adults with SB to exercise even with electronic reminders. Support from therapists to combat deconditioning and develop coping skills may be needed. PMID:24620701

    Non-attendance at outpatient clinics is common and costly. This study aimed to determine if sending SMS ('short message service' or text message) reminders to patients before appointments reduced non-attendance. We collected outpatient data at Ballyfermot and Lucan Community Adult Mental Health Service, Dublin, Ireland during 6-month periods (a) immediately prior to the introduction of SMS reminders for outpatient appointments; (b) immediately following the introduction of SMS reminders; and (c) two and a half years later. In the 6-month period prior to SMS reminders, 2170 outpatient appointments were offered and there was a 22.2% non-attendance rate. In the 6-months following the introduction of SMS reminders, 2092 appointments were offered and the non-attendance rate fell to 13.9% (p < 0.001), with the lower non-attendance rate among those who did not receive SMS reminders (9.7%) rather than those who did (15.7%) (p = 0.0002). There were 98 appointment cancellations during this period (73% via SMS messaging). In the 6-month period two and a half years after the introduction of SMS reminders, 2474 appointments were offered and the non-attendance rate rose to 19.3%; this did not differ between those who received SMS reminders (19.3%) and those who did not (19.1%) (p = 0.38209) and was still lower than the rate prior to SMS reminders (p = 0.01321). During this period, 197 appointments were cancelled (75% via SMS messaging). The chief value of SMS reminders lies not in reminding patients of appointments but in providing a convenient way to cancel them, thus allowing more appointments to be offered.

    The use of mobile phones to deliver health care (mHealth) is increasing in popularity due to the high prevalence of mobile phone penetration. This is seen in developing countries, where mHealth may be particularly useful in overcoming traditional access barriers. Non-communicable diseases may be particularly amenable to mHealth interventions, and hypertension is one with an escalating burden in the developing world. The objective of this study was to test whether the dissemination of health information via a short message service (SMS) led to improvements in health knowledge and self-reported health-related behaviors. A mixed methods study was carried out among a cohort of 223 hypertension clinic patients, in a resource-poor setting in Cape Town, South Africa, in 2012. Hypertensive outpatients were recruited at the clinic and administered a baseline questionnaire to establish existing knowledge of hypertension. Participants were then randomly assigned to intervention or control groups. The intervention group received 90 SMSes over a period of 17 weeks. Thereafter, the baseline questionnaire was readministered to both groups to gauge if any improvements in health knowledge had occurred. Those who received SMSes were asked additional questions about health-related behavior changes. A focus group was then conducted to obtain in-depth feedback about participants' experience with, and response to, the SMS campaign. No statistically significant changes in overall health knowledge were observed between the control and intervention groups. The intervention group had positive increases in self-reported behavior changes. These were reaffirmed by the focus groups, which also revealed a strong preference for the SMS campaign and the belief that the SMSes acted as a reminder to change, as opposed to providing new information. Although the content of the SMSes was not new, and did not improve health knowledge, SMSes were effective in motivating positive self-reported behavior

    Breastfeeding rates among mothers in the Supplemental Nutrition Program for Women, Infants, and Children (WIC) are lower than for other mothers in the United States. The objective of this study was to test the acceptability and feasibility of the Lactation Advice thru Texting Can Help intervention. Mothers were enrolled at 18-30 weeks gestation from two WIC breastfeeding peer counselling (PC) programmes if they intended to breastfeed and had unlimited text messaging, more than fifth-grade literacy level, and fluency in English or Spanish. Participants were randomized to the control arm (PC support without texting) or the intervention arm (PC support with texting). The two-way texting intervention provided breastfeeding education and support from peer counsellors. Primary outcomes included early post-partum (PP) contact and exclusive breastfeeding (EBF) rates at 2 weeks PP. Feasibility outcomes included text messaging engagement and mother's satisfaction with texting platform. Fifty-eight women were enrolled, 52 of whom were available for intention-to-treat analysis (n = 30 texting, n = 22 control). Contact between mothers and PCs within 48 hr of delivery was greater in the texting group (86.6% vs. 27.3%, p < .001). EBF rates at 2 weeks PP among participants in the texting intervention was 50% versus 31.8% in the control arm (p = .197). Intervention group mothers tended to be more likely to meet their breastfeeding goals (p = .06). Participants were highly satisfied with the Lactation Advice thru Texting Can Help intervention, and findings suggest that it may improve early post-delivery contact and increase EBF rates among mothers enrolled in WIC who receive PC. A large, multicentre trial is feasible and warranted. © 2017 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Behavioural brief interventions (BI can support people to reduce harmful drinking but multiple barriers impede the delivery and equitable access to these. To address this challenge, we developed YourCall™, a novel short message service (SMS text message intervention incorporating BI principles. This protocol describes a trial evaluating the effectiveness of YourCall™ (compared to usual care in reducing hazardous drinking and alcohol related harm among injured adults who received in-patient care. Methods/design Participants recruited to this single-blind randomised controlled trial comprised patients aged 16-69 years in three trauma-admitting hospitals in Auckland, New Zealand. Those who screened positive for moderately hazardous drinking were randomly assigned by computer to usual care (control group or the intervention. The latter comprised 16 informational and motivational text messages delivered using an automated system over the four weeks following discharge. The primary outcome is the difference in mean AUDIT-C score between the intervention and control groups at 3 months, with the maintenance of the effect examined at 6 and 12 months follow-up. Secondary outcomes comprised the health and social impacts of heavy drinking ascertained through a web-survey at 12 months, and further injuries identified through probabilistic linkage to national databases on accident insurance, hospital discharges, and mortality. Research staff evaluating outcomes were blinded to allocation. Intention-to-treat analyses will include assessment of interactions based on ethnicity (Māori compared with non-Māori.

    Particularly in groups of adolescents with lower educational level the smoking prevalence is still high and constitutes a serious public health problem. There is limited evidence of effective smoking cessation interventions in this group. Individualised text messaging (SMS) based interventions are promising to support smoking cessation and could be provided to adolescents irrespective of their motivation to quit. The aim of the current paper is to outline the study protocol of a trial testing the efficacy of an SMS based intervention for smoking cessation in apprentices. A two-arm cluster-randomised controlled trial will be conducted to test the efficacy of an SMS intervention for smoking cessation in adolescents and young adults compared to an assessment only control group. A total of 910 daily or occasional (≥ 4 cigarettes in the preceding month and ≥ 1 cigarette in the preceding week) smoking apprentices will be proactively recruited in vocational school classes and, using school class as a randomisation unit, randomly assigned to an intervention group (n = 455) receiving the SMS based intervention or an assessment only control group (n = 455). Individualised text messages taking into account demographic data and the individuals' smoking behaviours will be sent to the participants of the intervention group over a period of 3 months. Participants will receive two text messages promoting smoking cessation per week. Program participants who intend to quit smoking have the opportunity to use a more intensive SMS program to prepare for their quit day and to prevent a subsequent relapse. The primary outcome measure will be the proportion of participants with 7-day point prevalence smoking abstinence assessed at 6-months follow-up. The research assistants conducting the baseline and the follow-up assessments will be blinded regarding group assignment. It is expected that the program offers an effective and inexpensive way to promote smoking cessation among

    The Internet and mobile devices are increasingly used by men who have sex with men to find potential partners. Lack of partner information, besides e-mail addresses or user profiles, limits the ability to adequately perform partner notification by traditional means and test those at high risk. To streamline North Carolina Internet Partner Notification (IPN) services, University of North Carolina at Chapel Hill collaborated with the North Carolina Division of Public Health beginning in July 2011 to formalize state IPN and text messaging for partner notification (txtPN) policies and centralize notification practices by designating a single IPN/txtPN field coordinator within the University of North Carolina at Chapel Hill. We compared the number of IPN and txtPN contacts initiated and their outcomes in July 1, 2011, to June 30, 2012, and compared with outcomes in January 1, 2010, to December 31, 2010, the year before the collaboration. Overall, 362 IPN contacts were initiated compared with 133 initiated in 2010. More than half (59.1%) were black; mean age was 28.8 years. Almost all were men who have sex with men (83.7%). Approximately two-thirds (n = 230; 63.5%) of contacts were successfully notified using centralized IPN. Seven new cases of HIV infection, 11 new cases of syphilis, and 19 known previous HIV-positive persons were identified. Text messaging for partner notification was used for 29 contacts who did not initially respond to traditional notification or IPN; 14 (48%) responded to txtPN in a median time of 57.5 minutes (interquartile range, 9-2708). Centralization of IPN services augmented partner detection of new HIV and syphilis diagnoses. Text messaging for partner notification represents a potentially effective method for augmenting traditional partner services. In addition, IPN and txtPN allow identification of HIV-infected persons in need of linkage to care.

    Engagement with digital health interventions (DHIs) may be regarded as a prerequisite for the intervention to achieve positive health or behavior change outcomes. One method employed to promote engagement is the use of prompts such as emails and text messages. However, little is known about the characteristics of prompts that promote engagement. This study explored the association between the content and delivery mode of prompts and the users' engagement with HeLP-Diabetes (Healthy Living for People with type 2 Diabetes), a DHI that aimed to promote self-management in adults with type 2 diabetes. The objective of this study was to identify the characteristics of prompts, specifically the content and delivery mode, which were associated with increased engagement. This was a mixed-methods study. Email and text message prompts were sent to the registered users of HeLP-Diabetes. Use of the intervention was recorded and examined to identify which email and text message prompts were associated with subsequent visits to the DHI. Characteristics of prompts that were identified as particularly effective or ineffective were explored through think-aloud interviews with the participants. Of a total of 39 email prompts, 49% (19/39) prompts showed a significant association with subsequent visits to the DHI. However, none of the text message prompts were associated with subsequent visits to the DHI. Furthermore, think-aloud interviews were carried out with 6 experienced participants with type 2 diabetes. The findings suggest that these participants preferred email prompts that were clear, relatively short, and empowering; used nondirective advice; included health professional references; were visually appealing; and contained news and updates. The findings of this study contribute to the existing evidence supporting the role of email prompts in promoting and maintaining engagement with DHIs. This study described the content of prompts that may be engaging. However, the results

    ABSTRACT: BACKGROUND: Repeated data collection is desirable when monitoring fluctuating conditions. Mobile phones can be used to gather such data from large groups of respondents by sending and receiving frequently repeated short questions and answers as text messages. The analysis of repeated data...... and analytic approaches were illustrated and discussed, as well as the handling of missing data. In the applications the weekly outcome "number of days with pain" was analyzed in relation to the patients' "previous duration of pain" (categorized as more or less than 30 days in the previous year).

    Full Text Available Abstract Background Increasing intakes of fruits and vegetables intake, in tandem with reducing consumption of energy-dense and nutrient poor foods and beverages are dietary priorities to prevent chronic disease. Although most adults do not eat enough fruit and vegetables, teenagers and young adults tend to have the lowest intakes. Young adults typically consume a diet which is inconsistent with the dietary recommendations. Yet little is known about the best approaches to improve dietary intakes and behaviours among this group. This randomised controlled trial aims to evaluate the effectiveness of using a mobile device to assess dietary intake, provide tailored dietary feedback and text messages to motivate changes in fruit, vegetable and junk food consumption among young adults. Methods/design The CHAT project will involve the development of the mobile device food record (MDFR, and evaluation of dietary feedback and implementation of a 6-month intervention in young adults aged 18 to 30 years. The participants will be randomly assigned to one of three groups (1 Intervention Group 1: MDFR + Text Messages + Dietary Feedback; (2 Intervention Group 2: MDFR + Dietary Feedback; (3 Control Group 3: MDFR, no feedback. All groups will undertake a 3-day dietary record using the MDFR but only the Intervention Groups 1 and 2 will receive tailored dietary feedback at baseline and at 6-months which will consist of assessment of serves of fruits, vegetables and junk food in comparison to dietary recommendations. Tailored nutrition text messages will be sent to Intervention Group 1 over the 6 months. Data will be collected at baseline and again at the 6-month completion.

    Behavioural brief interventions (BI) can support people to reduce harmful drinking but multiple barriers impede the delivery and equitable access to these. To address this challenge, we developed YourCall™, a novel short message service (SMS) text message intervention incorporating BI principles. This protocol describes a trial evaluating the effectiveness of YourCall™ (compared to usual care) in reducing hazardous drinking and alcohol related harm among injured adults who received in-patient care. Participants recruited to this single-blind randomised controlled trial comprised patients aged 16-69 years in three trauma-admitting hospitals in Auckland, New Zealand. Those who screened positive for moderately hazardous drinking were randomly assigned by computer to usual care (control group) or the intervention. The latter comprised 16 informational and motivational text messages delivered using an automated system over the four weeks following discharge. The primary outcome is the difference in mean AUDIT-C score between the intervention and control groups at 3 months, with the maintenance of the effect examined at 6 and 12 months follow-up. Secondary outcomes comprised the health and social impacts of heavy drinking ascertained through a web-survey at 12 months, and further injuries identified through probabilistic linkage to national databases on accident insurance, hospital discharges, and mortality. Research staff evaluating outcomes were blinded to allocation. Intention-to-treat analyses will include assessment of interactions based on ethnicity (Māori compared with non-Māori). If found to be effective, this mobile health strategy has the potential to overcome current barriers to implementing equitably accessible interventions that can reduce harmful drinking.

    Background As the use of electronic cigarettes (e-cigarettes) rises, social media likely influences public awareness and perception of this emerging tobacco product. Objective This study examined the public conversation on Twitter to determine overarching themes and insights for trending topics from commercial and consumer users. Methods Text mining uncovered key patterns and important topics for e-cigarettes on Twitter. SAS Text Miner 12.1 software (SAS Institute Inc) was used for descriptive text mining to reveal the primary topics from tweets collected from March 24, 2015, to July 3, 2015, using a Python script in conjunction with Twitter’s streaming application programming interface. A total of 18 keywords related to e-cigarettes were used and resulted in a total of 872,544 tweets that were sorted into overarching themes through a text topic node for tweets (126,127) and retweets (114,451) that represented more than 1% of the conversation. Results While some of the final themes were marketing-focused, many topics represented diverse proponent and user conversations that included discussion of policies, personal experiences, and the differentiation of e-cigarettes from traditional tobacco, often by pointing to the lack of evidence for the harm or risks of e-cigarettes or taking the position that e-cigarettes should be promoted as smoking cessation devices. Conclusions These findings reveal that unique, large-scale public conversations are occurring on Twitter alongside e-cigarette advertising and promotion. Proponents and users are turning to social media to share knowledge, experience, and questions about e-cigarette use. Future research should focus on these unique conversations to understand how they influence attitudes towards and use of e-cigarettes. PMID:27956376

    This study was done to identify effects of a smoking cessation program including telephone counseling and text messaging using stages of change for outpatients who have had a myocardial infarction (MI). This research was a quasi-experimental design with a nonequivalent control group pretest-posttest. The participants were 48 outpatients (experimental group=24, control group=24) recruited from one university hospital. They were randomly assigned to one of two groups: (a) an experimental group with telephone counseling (once a week) and text messaging (five times a week) using stages of change, and (b) a control group with traditional telephone counseling (once a month). Efficacy of the intervention was measured by comparing the two groups on smoking-related variables at 3 weeks and 12 weeks. At the 3-week and 12-week measurements, there were significant differences between the experimental and control groups on smoking cessation self-efficacy (pstages of change is effective for outpatients after a MI. Further attention should be paid to the intensity of the smoking cessation program and periods for long-term follow-up.

    Full Text Available Abstract Background Particularly in groups of adolescents with lower educational level the smoking prevalence is still high and constitutes a serious public health problem. There is limited evidence of effective smoking cessation interventions in this group. Individualised text messaging (SMS based interventions are promising to support smoking cessation and could be provided to adolescents irrespective of their motivation to quit. The aim of the current paper is to outline the study protocol of a trial testing the efficacy of an SMS based intervention for smoking cessation in apprentices. Methods/Design A two-arm cluster-randomised controlled trial will be conducted to test the efficacy of an SMS intervention for smoking cessation in adolescents and young adults compared to an assessment only control group. A total of 910 daily or occasional (≥ 4 cigarettes in the preceding month and ≥ 1 cigarette in the preceding week smoking apprentices will be proactively recruited in vocational school classes and, using school class as a randomisation unit, randomly assigned to an intervention group (n = 455 receiving the SMS based intervention or an assessment only control group (n = 455. Individualised text messages taking into account demographic data and the individuals' smoking behaviours will be sent to the participants of the intervention group over a period of 3 months. Participants will receive two text messages promoting smoking cessation per week. Program participants who intend to quit smoking have the opportunity to use a more intensive SMS program to prepare for their quit day and to prevent a subsequent relapse. The primary outcome measure will be the proportion of participants with 7-day point prevalence smoking abstinence assessed at 6-months follow-up. The research assistants conducting the baseline and the follow-up assessments will be blinded regarding group assignment. Discussion It is expected that the program offers an effective

    There are conflicting findings about whether mobile phone text message reminders impact on antiretroviral adherence. We hypothesized that text reminders sent when dosing was late would improve adherence and HIV viral suppression. Antiretroviral therapy (ART)-naive participants, from a South African outpatient ART clinic, were randomized to standard of care (SoC, 3 pretreatment education sessions), or intervention (SoC and automated text reminders if dosing >30 minutes late). Dosing time was recorded by real-time electronic adherence monitoring devices, given to participants at ART start. CD4 cell count and HIV RNA were determined at baseline, 16 and 48 weeks. Primary outcome was cumulative adherence execution by electronic adherence monitoring device. HIV-1 viral suppression (TIs) >72 hours were secondary outcomes. Analysis was by intention to treat (missing = failure). Registration was with the Pan-African Clinical Trials Registry: PACTR201311000641402. A total of 230 participants were randomly assigned to control (n = 115) or intervention (n = 115) arms. Median adherence was 82.1% (interquartile range, 56.6%-94.6%) in the intervention arm, compared with 80.4% (interquartile range, 52.8%-93.8%) for SoC [adjusted odds ratio for adherence 1.08; 95% confidence interval (CI): 0.77 to 1.52]. Suppressed HIV RNA (TIs of >72 hours was reduced (adjusted incident rate ratio, 0.84; 95% CI: 0.75 to 0.94). Text message reminders linked to late doses detected by real-time adherence monitoring reduced the number of prolonged TIs, but did not significantly improve adherence or viral suppression.

    Severe mental disorders like psychotic disorders including schizophrenia and schizoaffective disorders have a 12-month-prevalence of 2.6, bipolar disorders of 1.5% in Germany. The relapse risk is high; so many patients need intensive monitoring and lifelong treatment. A high medication adherence is essential for a successful treatment. But in practice, medication adherence is low and decreases over time. Telemedical care concepts might improve treatment and bridge gaps between in- and outpatient treatment. A telemedical care concept based on regular telephone calls and short text messages was developed. The primary objective is to assess whether regular telephone calls and text messages can improve the medication adherence of patients. Secondary objectives are the reduction of rehospitalization rates, the improvement of quality of life and of the severity of symptoms. The Tecla study (Post stationary telemedical care of patients with severe psychiatric disorders) is a two-armed prospective randomized controlled trial. The participants in the intervention group receive in addition to usual care regular telephone calls every 2 weeks and weekly text messages on patient-individual topics during a 6 months period. Patients in the control group receive only regular care. Inclusion criteria are a physician-diagnosed bipolar disorder, schizoaffective disorder or schizophrenia and a signed informed consent. Exclusion criteria are planned inpatient treatments within the next 6 months and being non-reachable by phone. After 3 and 6 months both groups receive follow up assessments. The primary objective of this study is the medication adherence that is measured with the Medication Adherence Report Scale, German version (MARS-D). The MARS-D is a self-report with five items. Adherent behaviour is mostly overestimated using self-reports. The strength of the MARS-D is to detect non-adherent behaviour. The original Medication Adherence Report Scale in English language (MARS-5) was

    Unintended pregnancy can negatively impact women's lives and is associated with poorer health outcomes for women and children. Many women, particularly in low- and middle-income countries, continue to face obstacles in avoiding unintended pregnancy. In the State of Palestine, a survey conducted in 2006 estimated that 38% of pregnancies are unintended. In 2014, unmet need for contraception was highest among young women aged 20-24 years, at 15%. Mobile phones are increasingly being used to deliver health support. Once developed, interventions delivered by mobile phone are often cheaper to deliver than face-to-face support. The London School of Hygiene and Tropical Medicine and the Palestinian Family Planning and Protection Association have partnered to develop and evaluate a contraceptive behavioural intervention for young women in Palestine delivered by mobile phone. The intervention was developed guided by behavioural science and consists of short, mobile phone text messages that contain information about contraception and behaviour change methods delivered over 4 months. We will evaluate the intervention by conducting a randomised controlled trial. Five hundred and seventy women aged 18-24 years, who do not report using an effective method of contraception, will be allocated with a 1:1 ratio to receive the intervention text messages or control text messages about trial participation. The primary outcome is self-reported acceptability of at least one method of effective contraception at 4 months. Secondary outcomes include the use of effective contraception, acceptability of individual methods, discontinuation, service uptake, unintended pregnancy and abortion. Process outcomes include knowledge, perceived norms, personal agency and intervention dose received. Outcomes at 4 months will be compared between arms using logistic regression. This trial will determine the effect of the intervention on young women's attitudes towards the most effective methods of

    Resumption of sex before complete wound healing after male circumcision may increase risk of postoperative surgical complications, and HIV acquisition and transmission. We aimed to determine the effect of text messaging to deter resumption of sex before 42 days postcircumcision. We conducted a randomized trial where men older than18 years who owned mobile phones and had just undergone circumcision were randomized to receive a series of text messages (n = 600) or usual care (n = 600). The primary outcome was self-reported resumption of sex before 42 days. Sex before 42 days was reported by 139 of 491 (28.3%) men in the intervention group and 124 of 493 (25.2%) men in the control group [relative risk = 1.13, 95% confidence interval (CI): 0.91 to 1.38, P = 0.3]. Men were more likely to resume early if they were married or had a live-in sexual partner [adjusted relative risk (aRR) 1.57, 95% CI: 1.18 to 2.08, P < 0.01]; in the month before circumcision had 1 (aRR: 1.50, 95% CI: 1.07 to 2.12, P = 0.02) or more than 1 (aRR: 1.81, 95% CI: 1.24 to 2.66, P < 0.01) sexual partner(s); had primary school or lower education (aRR: 1.62, 95% CI: 1.33 to 1.97, P< 0.001); were employed (aRR: 1.35, 95% CI: 1.05 to 1.72, P = 0.02); or were 21-30 years old (aRR: 1.58, 95% CI: 1.01 to 2.47, P = 0.05), 31-40 years old (aRR: 1.91, 95% CI: 1.18 to 3.09, P < 0.01), or older than 40 years (aRR: 1.76, 95% CI: 1.04 to 2.97, P = 0.03) compared with younger than 21 years. Text messaging as used in this trial did not reduce early resumption of sex after circumcision. We identified key risk factors for early resumption that need to be considered in circumcision programs.

    To compare the effectiveness of proactive telephone counselling, reactive telephone counselling and an internet- and text-message-based intervention with a self-help booklet for smoking cessation. A randomized controlled trial with equal allocation to four conditions: (1) proactive telephone counselling (n = 452), (2) reactive telephone counselling (n = 453), (3) internet- and text-message-based intervention (n = 453) and (4) self-help booklet (control) (n = 452). Denmark. Smokers who had participated previously in two national health surveys were invited. Eligibility criteria were daily cigarette smoking, age ≥ 16 years, having a mobile phone and e-mail address. Primary outcome was prolonged abstinence to 12 months from the end of the intervention period. At 12-month follow-up, higher prolonged abstinence was found in the proactive telephone counselling group compared with the booklet group [7.3 versus 3.6%, odds ratio (OR) = 2.2, 95% confidence interval (CI) = 1.2-4.0]. There was no clear evidence of a difference in prolonged abstinence between the reactive telephone counselling group or the internet-based smoking cessation program and the booklet group: 1.8 versus 3.6%, OR = 0.8, 95% CI = 0.6-1.2 and 5.3 versus 3.6%, OR = 1.6, 95% CI = 0.8-3.0, respectively. In the proactive telephone counselling group, the cost per additional 12-month quitter compared with the booklet group was £644. Proactive telephone counselling was more effective than a self-help booklet in achieving prolonged abstinence for 12 months. No clear evidence of an effect of reactive telephone counselling or the internet- and text-message-based intervention was found compared with the self-help booklet. © 2016 Society for the Study of Addiction.

    Alcohol use disorders (AUDs) and mood disorders commonly co-occur, and are associated with a range of negative outcomes for patients. Mobile phone technology has the potential to provide personalised support for such patients and potentially improve outcomes in this difficult-to-treat cohort. The aim of this study is to examine whether receiving supporting SMS text messages, following discharge from an inpatient dual diagnosis treatment programme, has a positive impact on mood and alcohol abstinence in patients with an AUD and a comorbid mood disorder. The present study is a single-blind randomised controlled trial. Patients aged 18-70 years who meet the criteria for both alcohol dependency syndrome/alcohol abuse and either major depressive disorder or bipolar disorder according to the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders IV Axis I will be randomised to receive twice-daily supportive SMS text messages for 6 months plus treatment as usual, or treatment as usual alone, and will be followed-up at 3, 6, 9 and 12 months postdischarge. Primary outcome measures will include changes from baseline in cumulative abstinence duration, which will be expressed as the proportion of days abstinent from alcohol in the preceding 90 days, and changes from baseline in Beck Depression Inventory scores. The trial has received full ethical approval from the St. Patrick's Hospital Research Ethics Committee (protocol 13/14). Results of the trial will be disseminated through peer-reviewed journal articles and at academic conferences.

    Full Text Available Abstract Background As in other countries worldwide, the prevalence of mental disorders in Germany is high. Although numerically a dense network of in- and outpatient psychiatric health services exists, the availability in rural and remote regions is insufficient. In rural regions, telemedical concepts can be a chance to unburden and complement the existing healthcare system. Telemedical concepts consisting of video or telephone consulting show first positive results, but there are only a few studies with a randomized controlled design. To improve the treatment of patients with mental disorders in rural regions, we developed a telemedical care concept based on telephone contacts and text-messages. The primary objective of this study is to evaluate the effects of the telemedical interventions on psychopathological outcomes, e. g. anxiety, depressive symptoms, and somatisation. Secondary objective of the study is the analysis of intervention effects on the frequency of medical contacts with healthcare services. Furthermore, the frequency of patients' crises and the frequency and kind of interventions, initiated by the project nurses will be evaluated. We will also evaluate the acceptance of the telemedical care concept by the patients. Methods/Design In this paper we describe a three-armed, randomized, controlled study. All participants are recruited from psychiatric day hospitals. The inclusion criteria are a specialist-diagnosed depression, anxiety disorder, adjustment disorder or a somatoform disorder and eligibility to participate in the study. Exclusion criteria are ongoing outpatient psychotherapy, planned interval treatment at the day clinic and expected recurrent suicidality and self-injuring behaviour. The interventions consist of regular patient-individual telephone consultations or telephone consultations with complementing text-messages on the patients' mobile phone. The interventions will be conducted during a time period of 6 months

    Hypertension, the leading cause of morbidity and mortality, affects more than 1 billion people and is responsible globally for 10 million deaths annually. Hypertension can be controlled on a national level; in Canada, for example, awareness, treatment, and control improved dramatically from only 16% in 1990 to 66% currently. The ongoing development, dissemination, and implementation of Hypertension Canada's clinical practice guidelines is considered to be responsible, in part, for achieving these high levels of control and the associated improvements in cardiovascular outcomes. A gap still exists between the evidence and the implementation of hypertension guidelines in Indigenous communities in Canada, as well as in low- and middle-income countries (LMICs). The rapid rise in the ownership and use of mobile phones globally and the potential for texting (short message service, SMS) to improve health literacy and to link the health team together with the patient served as a rationale for the Dream-Global study in both Canada and Tanzania. The primary objective of the Dream-Global study is to assess the effect of innovative technologies and changes in health services delivery on blood pressure (BP) control of Indigenous people in Canada and rural Tanzanians with hypertension using SMS messages and community BP measurement through task shifting with transfer of the measures electronically to the patient and the health care team members. This prospective, randomized blinded allocation study enrolls both adults with uncontrolled hypertension (medicated or unmedicated) and those without hypertension but at high risk of developing this condition who participate in a BP screening study. Participants will be followed for at least 12 months. The primary efficacy endpoint in this study will be assessed by analysis of variance. Descriptive data will be given with the mean and standard deviation for continuous data and proportions for ordinal data. Exploratory subgroup analyses

    There are an estimated 25.8 million American children and adults, equivalent to 8.3% of the US population, living with diabetes. Diabetes is particularly burdensome on minority populations. The use of mobile technologies for reaching broad populations is a promising approach, given its wide footprint and ability to deliver inexpensive personalized messages, to increase awareness of type 2 diabetes and promote behavior changes targeting risk factors associated with type 2 diabetes. As a part of the Beacon Community Cooperative Agreement Program, txt4health, a public-facing mobile health information service, was launched in 3 Beacon Communities: the Southeast Michigan Beacon Community in Detroit, MI, the Greater Cincinnati Beacon Community in Cincinnati, OH, and the Crescent City Beacon Community in New Orleans, LA. Txt4health is a mobile health information service designed to help people understand their risk for type 2 diabetes and become more informed about the steps they can take to lead healthy lives. The purpose of this investigation was to use the RE-AIM framework to document txt4health reach and adoption by focusing on enrollment and participant engagement in program pilots in Southeast Michigan and Greater Cincinnati. We conducted a retrospective records analysis of individual-level txt4health system data from participants in Southeast Michigan and Greater Cincinnati to determine participant usage of txt4health and engagement with the program. Results from the retrospective records analysis revealed that 5570 participants initiated the 2-step enrollment process via 1 of 3 enrollment strategies: text message, website, or directly with Beacon staff who signed participants up via the website. In total, 33.00% (1838/5570) of participants completed the 2-step enrollment process and were fully enrolled in the program. All participants (100.00%, 1620/1620) who enrolled via text message completed the entire 2-step enrollment process versus 5.52% (218/3950) of

    Early infant diagnosis of HIV infection is challenging in rural sub-Saharan Africa as blood samples are sent to central laboratories for HIV DNA testing, leading to delays in diagnosis and treatment initiation. Simple technologies to rapidly deliver results to clinics and notify mothers of test results would decrease many of these delays. The feasibility of using mobile phones to contact mothers was evaluated. In addition, the first two years of implementation of a national short message service (SMS) reporting system to deliver test results from the laboratory to the clinic were evaluated. The study was conducted in Macha, Zambia from 2013 to 2015 among mothers of HIV-exposed infants. Mothers were interviewed about mobile phone use and willingness to be contacted directly or through their rural health center. Mothers were contacted according to their preferred method of communication when test results were available. Mothers of positive infants were asked to return to the clinic as soon as possible. Dates of sample collection, delivery of test results to the clinic and notification of mothers were documented in addition to test results. Four hundred nineteen mothers and infants were enrolled. Only 30% of mothers had ever used a mobile phone. 96% of mobile phone owners were reached by study staff and 98% of mothers without mobile phones were contacted through their rural health center. Turnaround times for mothers of positive infants were approximately 2 weeks shorter than for mothers of negative infants. Delivery of test results by the national SMS system improved from 2013 to 2014, with increases in the availability of texted results (38 vs. 91%) and arrival of the texted result prior to the hardcopy report (27 vs. 83%). Texted results arriving at the clinic before the hardcopy were received a median of 19 days earlier. Four discrepancies between texted and hardcopy results were identified out of 340 tests. Mobile phone and text messaging technology has the

    Mental and physical fatigue while at work is common among emergency medical services (EMS) shift workers. Extended shifts (for example 24 hours) and excessive amounts of overtime work increase the likelihood of negative safety outcomes and pose a challenge for EMS fatigue-risk management. Text message-based interventions are a potentially high-impact, low-cost platform for sleep and fatigue assessment and distributing information to workers at risk of negative safety outcomes related to sleep behaviors and fatigue. We will conduct a pilot randomized trial with a convenience sample of adult EMS workers recruited from across the United States using a single study website. Participants will be allocated to one of two possible arms for a 90-day study period. The intervention arm will involve text message assessments of sleepiness, fatigue, and difficulty with concentration at the beginning, during, and end of scheduled shifts. Intervention subjects reporting high levels of sleepiness or fatigue will receive one of four randomly selected intervention messages promoting behavior change during shiftwork. Control subjects will receive assessment only text messages. We aim to determine the performance characteristics of a text messaging tool for the delivery of a sleep and fatigue intervention. We seek to determine if a text messaging program with tailored intervention messages is effective at reducing perceived sleepiness and/or fatigue among emergency medicine clinician shift workers. Additional aims include testing whether a theory-based behavioral intervention, delivered by text message, changes 'alertness behaviors'. The SleepTrackTXT pilot trial could provide evidence of compliance and effectiveness that would support rapid widespread expansion in one of two forms: 1) a stand-alone program in the form of a tailored/individualized sleep monitoring and fatigue reduction support service for EMS workers; or 2) an add-on to a multi-component fatigue risk management program

    Full Text Available Since the turn of the new millennium, the new media has continued to alter the communication configuration in modern societies. The social media tools have been influencing the way we interact and communicate. These wireless networks have confirmed that our world has indeed become a global village by creating a superhighway for communication possibilities never witnessed in human history. While scholars  have explored the roles of  some of the new media platforms e.g. Facebook  blogging, and twitter for private and public discourses(e.g., Taiwo, 2010; Presley, 2010, 2012,  previous studies in the use of SMS in Nigeria have concentrated more on sociolinguistic, lexical, or morpho-syntactic  features of text messages (e.g., Awonusi, 2004; Chiluwa, 2010. The present study, however, considers aspects of the new media discourse strategies as resources in a second language setting that demonstrate users’ bilingual creativity. It adopts a discursive-semiotic approach in its analytical paradigm to examine how participants, sharing the mobile protocols, deploy linguistic and non-linguistic facilities as well as contextual resources to create relationship and to enact meaning. The approaches of Discourse Analysis (DA and Semiotics (Schiffrin, 1994; Chandler, 2001 as well as insight from Computer-Mediated Communication (CMC, and Computer-Mediated Discourse Analysis (CMDA(Herring 2001, 2004;  O’Riley, 2005;  Herring, 2007 provide the theoretical underpinning for this study.  CMC and CMDA, for instance, have been used as tool kits to study and   to explain how the new media technologies influence the strategies with which language users within a given virtual sphere engage a wide range of audience through the virtual protocols. The study finds that the use of text messages has opened up creative ways of deploying the resources of a non-native language (English among bilinguals in Nigeria.

    Full Text Available Abstract Introduction The use of automated text messages has made it possible to identify different courses of low back pain (LBP, and it has been observed that pain often fluctuates and that absolute recovery is rather rare. The purpose of this study was to describe the prevalence of pain-free weeks and pain-free periods in subjects with non-specific LBP treated by chiropractors, and to compare subjects from two different countries in these aspects. Methods Data were obtained from two practice-based multicentre prospective outcome studies, one Danish and one Swedish, involving subjects being treated by chiropractors for non-specific LBP. Over 18 weeks, subjects answered a weekly automated text message question on the number of days in the past week that they had experienced bothersome LBP, i.e. a number between 0 and 7. The number of weeks in a row without any LBP at all ("zero weeks" as well as the maximum number of zero weeks in a row was determined for each individual. Comparisons were made between the two study samples. Estimates are presented as percentages with 95% confidence intervals. Results In the Danish and the Swedish populations respectively, 93/110 (85% and 233/262 (89% of the subjects were eligible for analysis. In both groups, zero weeks were rather rare and were most commonly (in 40% of the zero weeks reported as a single isolated week. The prevalence of pain free periods, i.e. reporting a maximum of 0, 1 or 2, or 3-6 zero weeks in a row, were similar in the two populations (20-31%. Smaller percentages were reported for ≥ 7 zero weeks in a row. There were no significant differences between the two study groups. Conclusion It was uncommon that chiropractic subjects treated for non-specific LBP experienced an entire week without any LBP at all over 18 weeks. When this occurred, it was most commonly reported for brief periods only. Hence, recovery in the sense that patients become absolutely pain free is rare, even in a primary

    Full Text Available Abstract Background Repeated data collection is desirable when monitoring fluctuating conditions. Mobile phones can be used to gather such data from large groups of respondents by sending and receiving frequently repeated short questions and answers as text messages. The analysis of repeated data involves some challenges. Vital issues to consider are the within-subject correlation, the between measurement occasion correlation and the presence of missing values. The overall aim of this commentary is to describe different methods of analyzing repeated data. It is meant to give an overview for the clinical researcher in order for complex outcome measures to be interpreted in a clinically meaningful way. Methods A model data set was formed using data from two clinical studies, where patients with low back pain were followed with weekly text messages for 18 weeks. Different research questions and analytic approaches were illustrated and discussed, as well as the handling of missing data. In the applications the weekly outcome “number of days with pain” was analyzed in relation to the patients’ “previous duration of pain” (categorized as more or less than 30 days in the previous year. Research questions with appropriate analytical methods 1: How many days with pain do patients experience? This question was answered with data summaries. 2: What is the proportion of participants “recovered” at a specific time point? This question was answered using logistic regression analysis. 3: What is the time to recovery? This question was answered using survival analysis, illustrated in Kaplan-Meier curves, Proportional Hazard regression analyses and spline regression analyses. 4: How is the repeatedly measured data associated with baseline (predictor variables? This question was answered using generalized Estimating Equations, Poisson regression and Mixed linear models analyses. 5: Are there subgroups of patients with similar courses of pain

    Early adulthood represents the transition to independent living which is a period when changes in diet and body weight are likely to occur. This presents an ideal time for health interventions to reduce the effect of health problems and risk factors for chronic disease in later life. As young adults are high users of mobile devices, interventions that use this technology may improve engagement. The Connecting Health and Technology study aimed to evaluate the effectiveness of tailored dietary feedback and weekly text messaging to improve dietary intake of fruit, vegetables and junk food over 6 months among a population-based sample of men and women (aged 18-30 years). A three-arm, parallel, randomized control trial was conducted. After baseline assessments, participants were randomized to one of three groups: A) dietary feedback and weekly text messages, B) dietary feedback only or C) control group. Dietary intake was assessed using a mobile food record App (mFR) where participants captured images of foods and beverages consumed over 4-days at baseline and post-intervention. The primary outcomes were changes in serves of fruits, vegetables, energy-dense nutrient-poor (EDNP) foods and sugar-sweetened beverages (SSB). The intervention effects were assessed using linear mixed effect models for change in food group serves. Young adults (n = 247) were randomized to group A (n = 82), group B (n = 83), or group C (n = 82). Overall, no changes in food group serves for either intervention groups were observed. An unanticipated outcome was a mean weight reduction of 1.7 kg (P = .02) among the dietary feedback only. Men who received dietary feedback only, significantly reduced their serves of EDNP foods by a mean of 1.4 serves/day (P = .02). Women who received dietary feedback only significantly reduced their intake of SSB (P = .04) by an average of 0.2 serves/day compared with controls. Tailored dietary feedback only resulted in a decrease in EDNP

    Although there is great enthusiasm in both the public and private sector for the further development and use of large-scale consumer-facing public health applications for mobile platforms, little is known about user experience and satisfaction with this type of approach. As a part of the Beacon Community Cooperative Agreement Program, txt4health, a public-facing, mobile phone-based health information service targeting type 2 diabetes, was launched in 3 Beacon Communities: the Southeast Michigan Beacon Community in Detroit, MI, the Greater Cincinnati Beacon Community in Cincinnati, OH, and the Crescent City Beacon Community in New Orleans, LA. This program was marketed via large public health campaigns and drew many users within the respective communities. The purpose of this investigation was to use the RE-AIM framework to document txt4health efficacy by focusing on perceptions of satisfaction, usage, and behavior change among individuals who used txt4health in pilot studies in Southeast Michigan and Greater Cincinnati. We conducted a multimodal user survey with txt4health users recruited via text message through the program to understand participant perceptions of program use and satisfaction, as well as self-reported perceptions of behavior change as a result of using txt4health. Txt4health users reported very high levels of program satisfaction, with 67.1% (108/161) reporting satisfaction scores of ≥8 on a 10-point scale, with 10 equivalent to most satisfied (mean 8.2, SD 1.6). All survey participants agreed/strongly agreed that the messages included in txt4health were clear and easy to understand (100.0%, 160/160), and most found txt4health made them knowledgeable about their risk for type 2 diabetes (88.1%, 140/159) and made them conscious of their diet and physical activity (88.8%, 142/160). Most participants reported that txt4health helped them to make behavior changes related to diet; after having completed txt4health, most agreed/strongly agreed that

    Smoking represents an important health risk for people living with HIV (PLHIV). Low adherence to smoking cessation pharmacotherapy may limit treatment effectiveness. In this study, 158 participants recruited from three HIV care centers in New York City were randomized to receive 12-weeks of varenicline (Chantix) either alone as standard care (SC) or in combination with text message (TM) support or TM plus cell phone-delivered adherence-focused motivational and behavioral therapy (ABT). Generalized linear mixed-effect models found a significant decline in varenicline adherence from week 1-12 across treatment groups. At 12-weeks, the probability of smoking abstinence was significantly higher in SC+TM+ABT than in SC. The study demonstrates the feasibility of delivering adherence-focused interventions to PLHIV who smoke. Findings suggest intensive behavioral support is an important component of an effective smoking cessation intervention for this population, and a focus on improving adherence self-efficacy may lead to more consistent adherence and higher smoking abstinence.

    Public access defibrillation rarely reaches out-of-hospital cardiac arrest (OHCA) patients in residential areas. We developed a text message (TM) alert system, dispatching local lay rescuers (TM-responders). We analyzed the functioning of this system, focusing on response times and early defibrillation in relation to other responders. In July 2013, 14112 TM-responders and 1550 automated external defibrillators (AEDs) were registered in a database residing with the dispatch center of two regions of the Netherlands. TM-responders living defibrillator was connected from February 2010 until July 2013. Electrocardiograms from all defibrillators were analyzed for connection and defibrillation time. Of all OHCAs, the dispatcher activated the TM-alert system 893 times (58.1%). In 850 cases ≥1 TM-responder received a TM-alert and in 738 cases ≥1 AED was available. A TM-responder AED was connected in 184 of all OHCAs (12.0%), corresponding with 23.1% of all connected AEDs. Of all used TM-responder AEDs, 87.5% were used in residential areas, compared to 71.6% of all other defibrillators. TM-responders with AEDs defibrillated mean 2:39 (min:sec) earlier compared to emergency medical services (median interval 8:00 [25-75th percentile, 6:35-9:49] vs. 10:39 [25-75th percentile, 8:18-13:23], Pdefibrillation in OHCA, particularly in residential areas.

    The provision of medical care in environments with high levels of ambient noise (HLAN), such as concerts or sporting events, presents unique communication challenges. Audio transmissions can be incomprehensible to the receivers. Text-based communications may be a valuable primary and/or secondary means of communication in this type of setting. To evaluate the usability of text-based communications in parallel with standard two-way radio communications during mass-gathering (MG) events in the context of HLAN. This Canadian study used outcome survey methods to evaluate the performance of communication devices during MG events. Ten standard commercially available handheld smart phones loaded with basic voice and data plans were assigned to health care providers (HCPs) for use as an adjunct to the medical team's typical radio-based communication. Common text messaging and chat platforms were trialed. Both efficacy and provider satisfaction were evaluated. During a 23-month period, the smart phones were deployed at 17 events with HLAN for a total of 40 event days or approximately 460 hours of active use. Survey responses from health care providers (177) and dispatchers (26) were analyzed. The response rate was unknown due to the method of recruitment. Of the 155 HCP responses to the question measuring difficulty of communication in environments with HLAN, 68.4% agreed that they "occasionally" or "frequently" found it difficult to clearly understand voice communications via two-way radio. Similarly, of the 23 dispatcher responses to the same item, 65.2% of the responses indicated that "occasionally" or "frequently" HLAN negatively affected the ability to communicate clearly with team members. Of the 168 HCP responses to the item assessing whether text-based communication improved the ability to understand and respond to calls when compared to radio alone, 86.3% "agreed" or "strongly agreed" that this was the case. The dispatcher responses (n = 21) to the same item also

    Hypertension (HTN) is an important problem in the United States, with an estimated 78 million Americans aged 20 years and older suffering from this condition. Health disparities related to HTN are common in the United States, with African Americans suffering from greater prevalence of the condition than whites, as well as greater severity, earlier onset, and more complications. Medication adherence is an important component of HTN management, but adherence is often poor, and simply forgetting to take medications is often cited as a reason. Mobile health (mHealth) strategies have the potential to be a low-cost and effective method for improving medication adherence that also has broad reach. Our goal was to determine the feasibility, acceptability, and preliminary clinical effectiveness of BPMED, an intervention designed to improve medication adherence among African Americans with uncontrolled HTN, through fully automated text messaging support. We conducted two parallel, unblinded randomized controlled pilot trials with African-American patients who had uncontrolled HTN, recruited from primary care and emergency department (ED) settings. In each trial, participants were randomized to receive either usual care or the BPMED intervention for one month. Data were collected in-person at baseline and one-month follow-up, assessing the effect on medication adherence, systolic and diastolic blood pressure (SBP and DBP), medication adherence self-efficacy, and participant satisfaction. Data for both randomized controlled pilot trials were analyzed separately and combined. A total of 58 primary care and 65 ED participants were recruited with retention rates of 91% (53/58) and 88% (57/65), respectively. BPMED participants consistently showed numerically greater, yet nonsignificant, improvements in measures of medication adherence (mean change 0.9, SD 2.0 vs mean change 0.5, SD 1.5, P=.26), SBP (mean change -12.6, SD 24.0 vs mean change -11.3, SD 25.5 mm Hg, P=.78), and DBP

    Increasingly, low-income inner-city patients with diabetes utilize emergency departments (EDs) for acute and chronic care. We seek to determine whether a scalable, low-cost, unidirectional, text message-based mobile health intervention (TExT-MED) improves clinical outcomes, increases healthy behaviors, and decreases ED utilization in a safety net population. We conducted an randomized controlled trial of 128 adult patients with poorly controlled diabetes (glycosylated hemoglobin [Hb A1C] level ≥8%) in an urban, public ED. The TExT-MED group received 2 daily text messages for 6 months in English or Spanish. The primary outcome was change in Hb A1C level. Secondary outcomes included changes in medication adherence, self-efficacy, performance of self-care tasks, quality of life, diabetes-specific knowledge, ED utilization, and patient satisfaction. Hb A1C level decreased by 1.05% in the TExT-MED group compared with 0.60% in the controls (Δ0.45; 95% confidence interval [CI] -0.27 to 1.17) at 6 months. Secondary outcomes favored the TExT-MED group, with the most sizable change observed in self-reported medication adherence (as measured by the Morisky Medication Adherence Scale, an 8-point validated scale with higher scores representing better adherence), which improved from 4.5 to 5.4 in the TExT-MED group compared with a net decrease of -0.1 in the controls (Δ1.1 [95% CI 0.1 to 2.1]). Effects were larger among Spanish speakers for both medication adherence (1.1 versus -0.3; Δ1.4; 95% CI 0.2 to 2.7) and Hb A1C (-1.2% versus -0.4%) in the TExT-MED group. The proportion of patients who used emergency services trended lower in the TExT-MED group (35.9% versus 51.6%; Δ15.7%; 95% CI 9.4% to 22%). Overall, 93.6% of respondents enjoyed TExT-MED and 100% would recommend it to family/friends. The TExT-MED program did not result in a statistically significant improvement in Hb A1C. However, trends toward improvement in the primary outcome of Hb A1C and other secondary

    Full Text Available Abstract Background Non-specific low back pain (LBP is known to be a fluctuating condition and there is a growing realisation that it consists of different subgroups of patients. The detailed course of pain is not known since traditional methods of data collection do not allow very frequent follow-ups. This is a limitation in relation to identification of subgroups with different course patterns. The objective of this pilot study was to see if it is possible to identify characteristic course-patterns of non-specific LBP in patients treated in a primary care setting. Methods Patients seeing a chiropractor for a new LBP episode were included after the first consultation and followed for 18 weeks by means of automatic short message service (SMS received and returned on their mobile phones. Every week they were asked how many days they had experienced LBP in the preceding week. The course of pain was studied for each individual and described as an early course (1st - 4th week and a late course (5th - 18th week, which was fitted into one of 13 predefined course patterns. Results A total of 110 patients were included from 5 chiropractic clinics, and the study sample consisted of the 78 patients who participated at least until week 12. Nine of the predefined patterns were identified within this population. The majority of patients improved within the first four weeks (63%, and such early improvement was associated with a generally favourable course. Conclusion Patients with nonspecific LBP were shown to have a number of different course-patterns. The next step is to explore whether the identified patterns relate to different LBP diagnoses.

    Mobile phone technology (mHealth) is a promising tool that has been used to improve HIV care in high-risk populations worldwide. Understanding patient perspectives of newly diagnosed men who have sex with men (MSM) in Lima, Peru during linkage and engagement in the HIV care continuum can help close the gaps in care following initial HIV diagnosis and ensure retention in continuous care. From June 2015 to March 2016, as part of a randomized controlled trial, 40 MSM participants were linked to care with an mHealth intervention within 3 months of HIV diagnosis at Via Libre clinic. For 12 weeks, participants agreed to receive weekly predetermined, standardized short message service (SMS), WhatsApp©, and/or Facebook© messages from an assigned HIV counselor. Text messaging was bi-directional, meaning participants could also send messages to their counselor at any time. In this qualitative study, we coded and thematically analyzed 947 SMS, 918 WhatsApp, and 2,694 Facebook bi-directional messages. Mean age of participants was 29.8 years (20-50); with 70 percent reporting some post-high school education and 73 percent self-identifying as homosexual. We identified six recurring themes that emerged from the data: (a) mental health symptoms; (b) coping behaviors; (c) interpersonal support; (d) physical symptoms; (e) HIV knowledge; and (f) care coordination. Participants sent text messages describing depressive symptoms and seeking mental health services during this initial stage of HIV care. For newly diagnosed MSM entering the HIV care continuum, a bi-directional mHealth intervention provided support to facilitate care while eliciting deeply personal mental and emotional states. Future interventions could benefit from using mHealth interventions as ancillary support for clinicians.

    Effective use of proven treatments for high blood pressure, a preventable health risk, is challenging for many patients. Prompts via mobile phone SMS-text messaging may improve adherence to clinic visits and treatment, though more research is needed on impact and patient perceptions of such support interventions, especially in low-resource settings. An individually-randomised controlled trial in a primary care clinic in Cape Town (2012-14), tested the effect of an adherence support intervention delivered via SMS-texts, on blood pressure control and adherence to medication, for hypertensive patients. ( ClinicalTrials.gov NCT02019823). We report on a qualitative evaluation that explored the trial participants' experiences and responses to the SMS-text messages, and identified barriers and facilitators to delivering adherence support via patients' own mobile phones. Two focus groups and fifteen individual interviews were conducted. We used comparative and thematic analysis approaches to identify themes and triangulated our analysis amongst three researchers. Most participants were comfortable with the technology of using SMS-text messages. Messages were experienced as acceptable, relevant and useful to a broad range of participants. The SMS-content, the respectful tone and the delivery (timing of reminders and frequency) and the relational aspect of trial participation (feeling cared for) were all highly valued. A subgroup who benefitted the most, were those who had been struggling with adherence due to high levels of personal stress. The intervention appeared to coincide with their readiness for change, and provided practical and emotional support for improving adherence behaviour. Change may have been facilitated through increased acknowledgement of their health status and attitudinal change towards greater self-responsibility. Complex interaction of psycho-social stressors and health service problems were reported as broader challenges to adherence behaviours

    Full Text Available Abstract Background This trial aims at testing the efficacy of weekly reminder and motivational text messages, compared to usual care in improving adherence to Highly Active Antiretroviral Treatment in patients attending a clinic in Yaoundé, Cameroon. Methods and Design This is a single-centered randomized controlled single-blinded trial. A central computer generated randomization list will be generated using random block sizes. Allocation will be determined by sequentially numbered sealed opaque envelopes. 198 participants will either receive the mobile phone text message or usual care. Our hypothesis is that weekly motivational text messages can improve adherence to Highly Active Antiretroviral Treatment and other clinical outcomes in the control group by acting as a reminder, a cue to action and opening communication channels. Data will be collected at baseline, three months and six months. A blinded program secretary will send out text messages and record delivery. Our primary outcomes are adherence measured by the visual analogue scale, self report, and pharmacy refill data. Our secondary outcomes are clinical: weight, body mass index, opportunistic infections, all cause mortality and retention; biological: Cluster Designation 4 count and viral load; and quality of life. Analysis will be by intention-to-treat. Covariates and subgroups will be taken into account. Discussion This trial investigates the potential of SMS motivational reminders to improve adherence to Highly Active Antiretroviral Treatment in Cameroon. The intervention targets non-adherence due to forgetfulness and other forms of non-adherence.

    Schizophrenia is a high-cost, chronic, serious mental illness. There is a clear need to improve treatments and expand access to care for persons with schizophrenia, but simple, tailored interventions are missing. To evaluate the impact of tailored mobile telephone text messages to encourage adherence to medication and to follow up with people with psychosis at 12 months. Mobile.Net is a pragmatic randomized trial with inpatient psychiatric wards allocated to two parallel arms. The trial will include 24 sites and 45 psychiatric hospital wards providing inpatient care in Finland. The participants will be adult patients aged 18-65 years, of either sex, with antipsychotic medication (Anatomical Therapeutic Chemical classification 2011) on discharge from a psychiatric hospital, who have a mobile phone, are able to use the Finnish language, and are able to give written informed consent to participate in the study. The intervention group will receive semiautomatic system (short message service [SMS]) messages after they have been discharged from the psychiatric hospital. Patients will choose the form, content, timing, and frequency of the SMS messages related to their medication, keeping appointments, and other daily care. SMS messages will continue to the end of the study period (12 months) or until participants no longer want to receive the messages. Patients will be encouraged to contact researchers if they feel that they need to adjust the message in any way. At all times, both groups will receive usual care at the discretion of their team (psychiatry and nursing). The primary outcomes are service use and healthy days by 12 months based on routine data (admission to a psychiatric hospital, time to next hospitalization, time in hospital during this year, and healthy days). The secondary outcomes are service use, coercive measures, medication, adverse events, satisfaction with care, the intervention, and the trial, social functioning, and economic factors. Data will be

    Mobile technologies for health (mHealth) represent a promising strategy for reducing type 2 diabetes (T2DM) risk. The PROPELS trial investigates whether structured group-based education alone or supplemented with a follow-on support program combining self-monitoring with pedometers and tailored text-messaging is effective in promoting and maintaining physical activity among people at high risk of T2DM. This paper describes the iterative development of the PROPELS follow-on support program and presents evidence on its acceptability and feasibility. We used a modified mHealth development framework with four phases: (1) conceptualization of the follow-on support program using theory and evidence, (2) formative research including focus groups (n=15, ages 39-79 years), (3) pre-testing focus groups using a think aloud protocol (n=20, ages 52-78 years), and (4) piloting (n=11). Analysis was informed by the constant comparative approach, with findings from each phase informing subsequent phases. The first three phases informed the structure, nature, and content of the follow-on support program, including the frequency of text messages, the need for tailored content and two-way interaction, the importance of motivational messages based on encouragement and reinforcement of affective benefits (eg, enjoyment) with minimal messages about weight and T2DM risk, and the need for appropriate language. The refined program is personalized and tailored to the individual's perceived confidence, previous activity levels, and physical activity goals. The pilot phase indicated that the program appeared to fit well with everyday routines and was easy to use by older adults. We developed a feasible and innovative text messaging and pedometer program based on evidence and behavior change theory and grounded in the experiences, views, and needs of people at high diabetes risk. A large scale trial is testing the effectiveness of this 4-year program over and above structured group education

    Full Text Available To evaluate feasibility of self-assessment of medical abortion outcome using a low-sensitivity urine pregnancy test, checklist and text messages. The study assessed whether accurate self-assessment required a demonstration of the low-sensitivity urine pregnancy test or if verbal instructions suffice.This non-inferiority trial enrolled 525 adult women from six public sector abortion clinics. Eligible women were undergoing medical abortion at gestations within 63 days. Consenting women completed a baseline interview, received standard care with mifepristone and home-administration of misoprostol. All were given a low-sensitivity urine pregnancy test and checklist for use 14 days later, sent text reminders, and asked to attend in-clinic follow-up after two weeks. Women were randomly assigned 1:1 to an instruction-only group (n = 262; issued with pre-scripted instructions on the low-sensitivity pregnancy test, or a demonstration group (n = 263; performed practice tests guided by lay health workers. The primary outcome was accurate self-assessment of incomplete abortion, defined as needing additional misoprostol or vacuum aspiration. Analysis was by intention to treat and a non-inferiority margin was set to six percentage points. Women's acceptability of their abortion procedure and preferences for follow-up were also assessed.Follow-up was 81% for abortion outcome, confirmed in-clinic at two weeks or self-reported within six months. Non-inferiority of instruction-only to a demonstration was inconclusive for accurate self-assessment (risk difference for instruction-only -demonstration: -2.5%; 95%CI: -9% to 4%. Comparing instruction-only to demonstration groups, 99% and 100% found the pregnancy test easy to do; and 91% and 93% respectively chose the pregnancy test, checklist and text messages for abortion outcome assessment in the future.Routine self-assessment using a low-sensitivity pregnancy test, checklist and text messages is feasible and

    The psychological construct, readiness to change, is established as a central construct within behavioral change theories such as motivational interviewing (MI). Less is known about the interplay of mechanisms for change within adolescent treatment populations. Understanding the timing and interactive influence that adolescents' readiness to stop smoking and peer smoking have on subsequent tobacco use is important to advance intervention research. Toward this end, we used ecological momentary assessment (EMA) data from an automated texting smoking intervention randomized controlled trial to model the interactive effects of readiness to stop smoking and friends smoking on adolescent tobacco use. Two hundred adolescents were randomized into experimental treatment or attention control conditions, provided smart phones, and were followed for 6 months. African American youth represented the majority of the sample. We collected monthly EMA data for 6 months on friends smoking and readiness to stop smoking as well as survey outcome data. We tested a moderated mediation model using bias corrected bootstrapping to determine if the indirect effect of treatment on cigarettes smoked through readiness to stop smoking was moderated by friends smoking. Findings revealed that readiness to stop smoking mediated the effects of treatment on cigarettes smoked for those adolescents with fewer friends smoking, but not for those with more friends smoking. These results support importance of peer-focused interventions with urban adolescents and provide target mechanisms for future research. Copyright © 2015 Elsevier Inc. All rights reserved.

  9. Reducing stock-outs of life saving malaria commodities using mobile phone text-messaging: SMS for life study in Kenya.

    Full Text Available Health facility stock-outs of life saving malaria medicines are common across Africa. Innovative ways of addressing this problem are urgently required. We evaluated whether SMS based reporting of stocks of artemether-lumefantrine (AL and rapid diagnostic tests (RDT can result in reduction of stock-outs at peripheral facilities in Kenya.All 87 public health facilities in five Kenyan districts were included in a 26 week project. Weekly facility stock counts of four AL packs and RDTs were sent via structured incentivized SMS communication process from health workers' personal mobile phones to a web-based system accessed by district managers. The mean health facility response rate was 97% with a mean formatting error rate of 3%. Accuracy of stock count reports was 79% while accuracy of stock-out reports was 93%. District managers accessed the system 1,037 times at an average of eight times per week. The system was accessed in 82% of the study weeks. Comparing weeks 1 and 26, stock-out of one or more AL packs declined by 38 percentage-points. Total AL stock-out declined by 5 percentage-points and was eliminated by the end of the project. Stock-out declines of individual AL packs ranged from 14 to 32 percentage-points while decline in RDT stock-outs was 24 percentage-points. District managers responded to 44% of AL and 73% of RDT stock-out signals by redistributing commodities between facilities. In comparison with national trends, stock-out declines in study areas were greater, sharper and more sustained.Use of simple SMS technology ensured high reporting rates of reasonably accurate, real-time facility stock data that were used by district managers to undertake corrective actions to reduce stock-outs. Future work on stock monitoring via SMS should focus on assessing response rates without use of incentives and demonstrating effectiveness of such interventions on a larger scale.

    Screening is highly effective for cervical cancer prevention and control. Population-based screening programmes are widely implemented in high-income countries, although adherence is often low. In Portugal, just over half of the women adhere to cervical cancer screening, contributing for greater mortality rates than in other European countries. The most effective adherence raising strategies are based on patient reminders, small/mass media and face-to-face educational programmes, but sequential interventions targeting the general population have seldom been evaluated. The aim of this study is to assess the effectiveness of a stepwise approach, with increasing complexity and cost, to improve adherence to organised cervical cancer screening: step 1a-customised text message invitation; step 1b-customised automated phone call invitation; step 2-secretary phone call; step 3-family health professional phone call and face-to-face appointment. A population-based randomised controlled trial will be implemented in Portuguese urban and rural areas. Women eligible for cervical cancer screening will be randomised (1:1) to intervention and control. In the intervention group, women will be invited for screening through text messages, automated phone calls, manual phone calls and health professional appointments, to be applied sequentially to participants remaining non-adherent after each step. Control will be the standard of care (written letter). The primary outcome is the proportion of women adherent to screening after step 1 or sequences of steps from 1 to 3. The secondary outcomes are: proportion of women screened after each step (1a, 2 and 3); proportion of text messages/phone calls delivered; proportion of women previously screened in a private health institution who change to organised screening. The intervention and control groups will be compared based on intention-to-treat and per-protocol analyses. The study was approved by the Ethics Committee of the Northern Health

This non-inferiority trial enrolled 525 adult women from six public sector abortion clinics. Eligible women were undergoing medical abortion at gestations within 63 days. Consenting women completed a baseline interview, received standard care with mifepristone and home-administration of misoprostol. All were given a low-sensitivity urine pregnancy test and checklist for use 14 days later, sent text reminders, and asked to attend in-clinic follow-up after two weeks. Women were randomly assigned 1:1 to an instruction-only group (n = 262; issued with pre-scripted instructions on the low-sensitivity pregnancy test), or a demonstration group (n = 263; performed practice tests guided by lay health workers). The primary outcome was accurate self-assessment of incomplete abortion, defined as needing additional misoprostol or vacuum aspiration. Analysis was by intention to treat and a non-inferiority margin was set to six percentage points. Women's acceptability of their abortion procedure and preferences for follow-up were also assessed. Follow-up was 81% for abortion outcome, confirmed in-clinic at two weeks or self-reported within six months. Non-inferiority of instruction-only to a demonstration was inconclusive for accurate self-assessment (risk difference for instruction-only -demonstration: -2.5%; 95%CI: -9% to 4%). Comparing instruction-only to demonstration groups, 99% and 100% found the pregnancy test easy to do; and 91% and 93% respectively chose the pregnancy test, checklist and text messages for abortion outcome assessment in the future. Routine self-assessment using a low-sensitivity pregnancy test, checklist and text messages is feasible and preferred by women

    Introduction Screening is highly effective for cervical cancer prevention and control. Population-based screening programmes are widely implemented in high-income countries, although adherence is often low. In Portugal, just over half of the women adhere to cervical cancer screening, contributing for greater mortality rates than in other European countries. The most effective adherence raising strategies are based on patient reminders, small/mass media and face-to-face educational programmes, but sequential interventions targeting the general population have seldom been evaluated. The aim of this study is to assess the effectiveness of a stepwise approach, with increasing complexity and cost, to improve adherence to organised cervical cancer screening: step 1a—customised text message invitation; step 1b—customised automated phone call invitation; step 2—secretary phone call; step 3—family health professional phone call and face-to-face appointment. Methods A population-based randomised controlled trial will be implemented in Portuguese urban and rural areas. Women eligible for cervical cancer screening will be randomised (1:1) to intervention and control. In the intervention group, women will be invited for screening through text messages, automated phone calls, manual phone calls and health professional appointments, to be applied sequentially to participants remaining non-adherent after each step. Control will be the standard of care (written letter). The primary outcome is the proportion of women adherent to screening after step 1 or sequences of steps from 1 to 3. The secondary outcomes are: proportion of women screened after each step (1a, 2 and 3); proportion of text messages/phone calls delivered; proportion of women previously screened in a private health institution who change to organised screening. The intervention and control groups will be compared based on intention-to-treat and per-protocol analyses. Ethics and dissemination The study was

    Long-term human spaceflight means long-term menu planning. Since every pound of cargo comes with a steep price tag, NASA has long researched technologies and techniques to allow astronauts to grow their own food, both on the journey and in some cases at their destination. Sustainable food technologies designed for space have resulted in spinoffs that improve the nutrition, safety, and durability of food on Earth. There are of course tradeoffs involved in making astronauts part-time farmers. Any time spent tending plants is time that can t be spent elsewhere: collecting data, exploring, performing routine maintenance, or sleeping. And as scarce as time is for astronauts, resources are even more limited. It is highly practical, therefore, to ensure that farming in space is as automated and precise as possible.

    Popularity of social marketing messages indicates the effectiveness of the corresponding marketing strategies. This research aims to discover the characteristics of social marketing messages that contribute to different level of popularity. Using messages posted by a sample of restaurants on Facebook as a case study, we measured the message popularity by the number of "likes" voted by fans, and examined the relationship between the message popularity and two properties of the messages: (1) content, and (2) media type. Combining a number of text mining and statistics methods, we have discovered some interesting patterns correlated to "more popular" and "less popular" social marketing messages. This work lays foundation for building computational models to predict the popularity of social marketing messages in the future.

    Many physicians and practice staff use short messaging service (SMS) text messaging to communicate with patients. But SMS text messaging is unencrypted, insecure, and does not meet HIPAA requirements. In addition, the short and abbreviated nature of text messages creates opportunities for misinterpretation, and can negatively impact patient safety and care. Until recently, asking patients to sign a statement that they understand and accept these risks--as well as having policies, device encryption, and cyber insurance in place--would have been enough to mitigate the risk of using SMS text in a medical practice. But new trends and policies have made SMS text messaging unsafe under any circumstance. This article explains these trends and policies, as well as why only secure texting or secure messaging should be used for physician-patient communication.

    The present research aimed to test the efficacy of affective and instrumental text messages compared with a no-message control as a strategy to increase fruit and vegetable intake (FVI) in adolescents. A randomized controlled trial was used test impact of different text messages compared with no message on FVI over a 2-week period. A total of 1,065 adolescents (14-19 years) from a high school of the South of Italy completed the baseline questionnaire and were randomly allocated to one of three conditions: instrumental messages (N = 238), affective messages (N = 300), and no messages (N = 521). Students in the message conditions received one message each day over a 2-week period. The messages targeted affective (affective benefits) or instrumental (instrumental benefits) information about FVI. Self-reported FVI at 2 weeks was the key dependent variable. Analyses were based on the N = 634 who completed all aspects of the study. Findings showed that messages significantly increased FVI, particularly in the affective condition and this effect was partially mediated by changes in affective attitude and intentions towards FVI. Text messages can be used to increase FVI in adolescents. Text messages based on affective benefits are more effective than text messages based on instrumental benefits. Statement of contribution What is already known on this subject? Text messages have been shown to promote positive change in health behaviours. However, the most appropriate target for such text messages is less clear although targeting attitudes may be effective. What does this study add? This randomized controlled study shows that text messages targeting instrumental or affective attitudes produce changes in fruit and vegetable intake (FVI) in adolescents. Text messages targeting affective attitudes are shown to be more effective than text messages targeting instrumental attitudes. The effect of affective text messages on FVI was partially mediated by changes in

    2013-03-01

    Mobile Health (mHealth) has emerged as a promising direction for delivery of healthcare services via mobile communication devices such as cell phones. Examples include texting-based interventions for chronic disease monitoring, diabetes management, control of hypertension, smoking cessation, monitoring medication adherence, appointment keeping and medical test result delivery; as well as improving patient-provider communication, health information communication, data collection and access to health records. While existing messaging systems very well support bulk messaging and some polling applications, they are not designed for data collection and processing of health research oriented studies. For that reason known studies based on text-messaging campaigns have been constrained in participant numbers. In order to empower healthcare promotion and education research, this paper presents a system dedicated for healthcare research. It is designed for convenient communication with various study groups, feedback collection and automated processing.

    Full Text Available This 21st century will witness great advances in science and technology, many of which are certain to improve quality of life. Though numerous advances provide benefits, we still face the challenge of infectious diseases, which emerge or remerge, naturally or otherwise. The outbreak of the Ebola virus disease in West Africa at the end of 2013 is a case in point. It has continued for over a year and spread from the known origin of Guinea to neighboring countries, and reached the United States, Europe, and Asia through international travel. This outbreak accelerated translational research on vaccines and practical therapeutics. Thus, basic research paved the way for translational medicine. The driver for translational medicine is human health needs. In the era of the Internet, it is inevitable that people take full advantage of all this powerful tool can offer. The most obvious feature of the Internet age is the free sharing of knowledge and other information. In this regard, there is a need for a platform to share knowledge about infectious diseases and translational medicine. This journal, Infectious Diseases and Translational Medicine (IDTM, was designed to meet this requirement. We editors hope that this new journal will help our colleagues in exchanging ideas and bridging the gaps between basic research and translational medicine. We also hope that our readers will help in sharing their efforts with their colleagues by means of this platform. IDTM is a peer-reviewed, double-blinded, open-access, high-quality platform for online publication in both PDF and HTML formats. The journal is devoted to basic, applied, and translational research of infectious diseases. It includes diagnostics, therapeutics, and preventive countermeasures as well as related basic research, focusing on genomics, proteomics, and other omics-driven research to examine such areas as evolution, pathogenesis, and epidemiology. Here, we are formally announcing the launch of

    Full Text Available Abstract Background To motivate individuals to adhere to a regular physical activity regime, guidelines must be supplemented with persuasive messages that are disseminated widely. While substantial research has examined effective strategies for disseminating physical activity messages, there has been no systematic effort to examine optimal message content. This paper reviews studies that evaluate the effectiveness of three approaches for constructing physical activity messages including tailoring messages to suit individual characteristics of message recipients (message tailoring, framing messages in terms of gains versus losses (message framing, and targeting messages to affect change in self-efficacy (i.e., a theoretical determinant of behavior change. Methods We searched the MEDLINE, PsycINFO, EMBASE and CINAHL databases up to July 2008. Relevant reference lists also were searched. We included intervention trials, field experiments, and laboratory-based studies that aimed to test the efficacy or effectiveness of tailored messages, framed messages and self-efficacy change messages among healthy adults. We used a descriptive approach to analyze emerging patterns in research findings. Based on this evidence we made recommendations for practice and future research. Results Twenty-two studies were identified. Twelve studies evaluated message tailoring. In 10 of these studies, tailored messages resulted in greater physical activity than a control message. Six studies evaluated framed messages. Five of these studies demonstrated that gain-framed messages lead to stronger intentions to be active compared to a control message. Moreover, a gain-frame advantage was evident in three of the four studies that assessed physical activity. Four studies evaluated self-efficacy change messages. The two studies that used an experimental design provide a clear indication that individuals' beliefs can be affected by messages that incorporate types of information

    Audio steganography is about hiding the secret message into the audio. It is a technique uses to secure the transmission of secret information or hide their existence. It also may provide confidentiality to secret message if the message is encrypted. To date most of the steganography software such as Mp3Stego and DeepSound use block cipher such as Advanced Encryption Standard or Data Encryption Standard to encrypt the secret message. It is a good practice for security. However, the encrypted message may become too long to embed in audio and cause distortion of cover audio if the secret message is too long. Hence, there is a need to encrypt the message with stream cipher before embedding the message into the audio. This is because stream cipher provides bit by bit encryption meanwhile block cipher provide a fixed length of bits encryption which result a longer output compare to stream cipher. Hence, an audio steganography with embedding text with Rivest Cipher 4 encryption cipher is design, develop and test in this project.

    Instant messaging may compromise sleep quality and school performance in adolescents. We aimed to determine associations between nighttime messaging and daytime sleepiness, self-reported sleep parameters, and/or school performance. Students from 3 high schools in New Jersey completed anonymous questionnaires assessing sleep duration, daytime sleepiness, messaging habits, and academic performance. Of the 2,352 students sampled, 1,537 responses were contrasted among grades, sexes, and messaging duration, both before and after lights out. Students who reported longer duration of messaging after lights out were more likely to report a shorter sleep duration, higher rate of daytime sleepiness, and poorer academic performance. Messaging before lights out was not associated with higher rates of daytime sleepiness or poorer academic performance. Females reported more messaging, more daytime sleepiness, and better academic performance than males. There may be an association between text messaging and school performance in this cohort of students. © The Author(s) 2016.

    2015-01-01

    A direct connection between certain lifestyle factors and an increased risk of cancer has already been established. Despite well-documented associations, controversial messages on causes of cancer often appear without taking into consideration their impact on the general population. While mainstream coverage of cancer research is clearly welcome, consideration must be given to the risk of transmitting provocative messages with serious negative consequences for cancer research and public health. We must avoid becoming a breeding ground for the misinterpretation of scientific information. Polemical results can stimulate scientific research and progress, but controversial messages encourage confusion and impotence in an increasingly disoriented population. The correct communication of health messages is at least as important as research on risk factors.

    Full Text Available Abstract Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.

    Full Text Available Following HIV-1 acquisition, many individuals develop an acute retroviral syndrome and a majority seek care. Available antibody testing cannot detect an acute HIV infection, but repeat testing after 2-4 weeks may detect seroconversion. We assessed the effect of appointment reminders on attendance for repeat HIV testing.We enrolled, in a randomized controlled trial, 18-29 year old patients evaluated for acute HIV infection at five sites in Coastal Kenya (ClinicalTrials.gov NCT01876199. Participants were allocated 1:1 to either standard appointment (a dated appointment card or enhanced appointment (a dated appointment card plus SMS and phone call reminders, or in-person reminders for participants without a phone. The primary outcome was visit attendance, i.e., the proportion of participants attending the repeat test visit. Factors associated with attendance were examined by bivariable and multivariable logistic regression.Between April and July 2013, 410 participants were randomized. Attendance was 41% (85/207 for the standard group and 59% (117/199 for the enhanced group, for a relative risk of 1.4 [95% Confidence Interval, CI, 1.2-1.7].Higher attendance was independently associated with older age, study site, and report of transactional sex in past month. Lower attendance was associated with reporting multiple partners in the past two months.Appointment reminders through SMS, phone calls and in-person reminders increased the uptake of repeat HIV test by forty percent. This low-cost intervention could facilitate detection of acute HIV infections and uptake of recommended repeat testing.Clinicaltrials.gov NCT01876199.

    Full Text Available Mobile messaging is evolving beyond SMS (Short Message Service text messaging with the introduction of MMS (Multimedia Messaging Service. In the past, such a scheme is used for peer-to-peer communication. Messages are generally displayed on a cellular phone with a limited-sized screen. However, such a visualizing process is not suitable to broadcast real-time SMS/MMS messages to people in public. To facilitate the instancy and publicity, we develop a real-time information aggregator—Visualizing SMS and MMS Messages System (VSMMS—to realize the concept by integrating SMS and MMS messaging over GSM/GPRS/UMTS onto a remote display device. The device exhibits messages on a larger display device in public. VSMMS features a revolutionized variation of mass media broadcasting. In this paper, we practically illustrate how to design and implement VSMMS and use a M/M/1 model to conduct a theoretical analysis about the message delay in the system queue. Meanwhile, we make an empirical performance evaluation about the message transmission time over different networks.

    2013-07-01

    Full Text Available Gender has been an important area of research in the field of popular music studies. Numerous scholars have found that contemporary popular music functions as a locus of diverse constructions and expressions of gender. While most studies focus on content analyses of popular music, there is still a need for more research on audience’s perception of popular music’s messages. This study examined adult Malay listeners’ perceptions of gender messages in contemporary Malay songs. A total of 16 contemporary Malay songs were analysed using Fairclough’s (1992 method of text analysis. The content of the songs that conveyed messages about gender were the basis for analysis. The results showed that the messages revolve mainly around socially constructed gender roles and expectations in romantic relationships. Gender stereotypes are also used in the songs to reinforce men’s and women’s roles in romantic relationships. The results also showed that, while listeners acknowledge the songs’ messages about gender, their own perceptions of gender and what it means to be a gendered being in today’s world are neither represented nor discussed fully in the songs analysed. It is hoped the findings from this, particularly the mismatch between projected and perceived notions of gender, contribute to the field of popular Malay music studies in particular, and popular music studies in general where gender messages in popular songs and their influence on listeners’ perceptions of their own gender is concerned.

  6. Engineered cell-cell communication via DNA messaging

    2012-09-01

    Full Text Available Abstract Background Evolution has selected for organisms that benefit from genetically encoded cell-cell communication. Engineers have begun to repurpose elements of natural communication systems to realize programmed pattern formation and coordinate other population-level behaviors. However, existing engineered systems rely on system-specific small molecules to send molecular messages among cells. Thus, the information transmission capacity of current engineered biological communication systems is physically limited by specific biomolecules that are capable of sending only a single message, typically “regulate transcription.” Results We have engineered a cell-cell communication platform using bacteriophage M13 gene products to autonomously package and deliver heterologous DNA messages of varying lengths and encoded functions. We demonstrate the decoupling of messages from a common communication channel via the autonomous transmission of various arbitrary genetic messages. Further, we increase the range of engineered DNA messaging across semisolid media by linking message transmission or receipt to active cellular chemotaxis. Conclusions We demonstrate decoupling of a communication channel from message transmission within engineered biological systems via the autonomous targeted transduction of user-specified heterologous DNA messages. We also demonstrate that bacteriophage M13 particle production and message transduction occurs among chemotactic bacteria. We use chemotaxis to improve the range of DNA messaging, increasing both transmission distance and communication bit rates relative to existing small molecule-based communication systems. We postulate that integration of different engineered cell-cell communication platforms will allow for more complex spatial programming of dynamic cellular consortia.

  8. Improving Type Error Messages in OCaml

    Directory of Open Access Journals (Sweden)

    Arthur Charguéraud

    2015-12-01

    Full Text Available Cryptic type error messages are a major obstacle to learning OCaml or other ML-based languages. In many cases, error messages cannot be interpreted without a sufficiently-precise model of the type inference algorithm. The problem of improving type error messages in ML has received quite a bit of attention over the past two decades, and many different strategies have been considered. The challenge is not only to produce error messages that are both sufficiently concise and systematically useful to the programmer, but also to handle a full-blown programming language and to cope with large-sized programs efficiently. In this work, we present a modification to the traditional ML type inference algorithm implemented in OCaml that, by significantly reducing the left-to-right bias, allows us to report error messages that are more helpful to the programmer. Our algorithm remains fully predictable and continues to produce fairly concise error messages that always help making some progress towards fixing the code. We implemented our approach as a patch to the OCaml compiler in just a few hundred lines of code. We believe that this patch should benefit not just to beginners, but also to experienced programs developing large-scale OCaml programs.

    Wang, Shin-Ywan; Burleigh, Scott C.

    2011-01-01

    The Remote Asynchronous Message Service (RAMS) gateway is a special-purpose AMS application node that enables exchange of AMS messages between nodes residing in different AMS "continua," notionally in different geographical locations. JPL s implementation of RAMS gateway functionality is integrated with the ION (Interplanetary Overlay Network) implementation of the DTN (Delay-Tolerant Networking) bundle protocol, and with JPL s implementation of AMS itself. RAMS protocol data units are encapsulated in ION bundles and are forwarded to the neighboring RAMS gateways identified in the source gateway s AMS management information base. Each RAMS gateway has interfaces in two communication environments: the AMS message space it serves, and the RAMS network - the grid or tree of mutually aware RAMS gateways - that enables AMS messages produced in one message space to be forwarded to other message spaces of the same venture. Each gateway opens persistent, private RAMS network communication channels to the RAMS gateways of other message spaces for the same venture, in other continua. The interconnected RAMS gateways use these communication channels to forward message petition assertions and cancellations among themselves. Each RAMS gateway subscribes locally to all subjects that are of interest in any of the linked message spaces. On receiving its copy of a message on any of these subjects, the RAMS gateway node uses the RAMS network to forward the message to every other RAMS gateway whose message space contains at least one node that has subscribed to messages on that subject. On receiving a message via the RAMS network from some other RAMS gateway, the RAMS gateway node forwards the message to all subscribers in its own message space.

  20. VISUAL ART AND REGULATORY FIT MESSAGES ON CONSUMER EVALUATIONS

    Directory of Open Access Journals (Sweden)

    Danielle Mantovani

    2016-03-01

    Full Text Available In this study, we demonstrate that the art infusion effect, in which the presence of visual art causes a positive impact on consumers’ perceptions of products and advertising messages, might have a moderation effect on regulatory fit and non-fit messages. We investigate the impact of visual art on advertisement evaluations in regulatory (non- fit conditions. Regulatory focus theory suggests that consumers rely on their motivational focus (prevention vs. promotion for their evaluations and decisions. Usually, consumers prefer products that fit with their personal motivational focus. In the present study, the results of three experiments indicate that using visual art with a promotion or prevention fit message is recommended, while non-art images increase message persuasiveness when non-fit messages are presented. Therefore, not all information compatible with the consumer’s motivational focus are best evaluated. When non-art images are presented, non-fit messages might be more persuasive.

    Full Text Available With the increased usage of online technologies, there has been an escalation of Electronic Word - of –Mouth (eWOM messages related to sport products and services offered and consumed. Therefore, in this original investigation by applying eWOM to the sport industry, this study examined how the combination of the quality of the eWOM message and the provider of the eWOM message affects purchaseintentions depending on the expertise level of the consumer. This study – which involved the collection of data from 134 students at a large university situated in the Midwest of the United States – utilized repeated measures of Analysis of Variance (ANOVA with tripartite groups of expertise and experimental conditions as independent variables. Purchase intention was the dependent variables. The results indicated that the quality of the eWOM message moderated the effect of the provider of the eWOM message. The subject’s level of expertise also had a moderating role on purchase intention.

    2012-02-01

    Full Text Available As the Internet begins to encapsulate more people within online communities, it is important that the social researcher have well-rounded ethnographic methodologies for observing these phenomena. This article seeks to contribute to methodology by detailing and providing insights into three specific facets of virtual ethnography that need attention: space and time, identity and authenticity, and ethics. Because the Internet is a globalized and instantaneous medium where space and time collapse, identity becomes more playful, and ethics become more tenuous; understanding these aspects is crucial to the study of online social groups. A second focus of this article is to apply these notions to the study of online message boards—a frequently used medium for online communication that is frequently overlooked by methodologists.

    Full Text Available Due to the rapid growth of the Internet and use of e-commerce in the recent years, viral marketing has drawn the attention of manufacturing and service organizations. However, no research has been conducted to examine the impact of message appeal and message source credibility on consumers’ attitude with mediating role of intellectual involvement of consumers and their risk taking level. The aim of this study was to examine the impact of appeal and message source credibility on consumers’ attitude with mediating role of consumers’ intellectual involvement and their risk taking level. The population of this study includes consumers of mobile phones (Samsung, Sony, Nokia, LG and iPhone in the Bushehr city (Iran. As the population of the study is unlimited, 430 questionnaires were distributed using available sampling method, and 391 questionnaires were collected and analyzed. Using structural equation modeling, we analysed the data through smart PLS software. The results show that the appeal and credibility of the message source impact the consumer attitudes toward the brand. We also found that the intellectual involvement of consumers plays the mediating role in the relationship between message appeal and consumer attitudes toward brands. In the relationship between message source credibility and customer attitude towards the brand, the level of risk taking of people has no mediating role.

  7. Creative Analytics of Mission Ops Event Messages

    2017-01-01

    Historically, tremendous effort has been put into processing and displaying mission health and safety telemetry data; and relatively little attention has been paid to extracting information from missions time-tagged event log messages. Todays missions may log tens of thousands of messages per day and the numbers are expected to dramatically increase as satellite fleets and constellations are launched, as security monitoring continues to evolve, and as the overall complexity of ground system operations increases. The logs may contain information about orbital events, scheduled and actual observations, device status and anomalies, when operators were logged on, when commands were resent, when there were data drop outs or system failures, and much much more. When dealing with distributed space missions or operational fleets, it becomes even more important to systematically analyze this data. Several advanced information systems technologies make it appropriate to now develop analytic capabilities which can increase mission situational awareness, reduce mission risk, enable better event-driven automation and cross-mission collaborations, and lead to improved operations strategies: Industry Standard for Log Messages. The Object Management Group (OMG) Space Domain Task Force (SDTF) standards organization is in the process of creating a formal standard for industry for event log messages.

    1995-01-01

    The International Conference on Population and Development held in Cairo in September 1994 recognized the need for reducing unwanted fertility and promoting smaller families within reproductive health services along with improving women's equality in education, health, and economic opportunity. The implementation of the main message would require an ideological transformation both for the population and for the development establishments. The implementation of a broadened population policy must incorporate the reduction of gender disparities as the primary goal. The problem is that the UNFPA has no influence over resources allocated to child health, female education, economic opportunities for women, or empowerment of women. Reproductive health and family planning programs should be integrated within the broader health services; however, reproductive health may not receive the desired high priority. Family planning programs are also expected to solve two problems: to improve individual well-being and to reduce overall fertility. Managers are likely to implement the reproductive health approach if it is a cost-effective way of reducing total fertility. However, no evidence exists to show that treating reproductive tract infections is a cost-effective way of reducing fertility. The primary objective of family planning programs should be empowerment of individuals to achieve their own reproductive goals in a healthful manner. Fertility reduction should be linked to fertility reduction by focusing on unwanted childbirth and to reproductive health services. The redesign of contraceptive services from a reproductive health perspective would deal with the contraindications of each method by developing standards for screening and focusing as well on the diagnosis and treatment of these conditions. The suggested role of the population sector in the tasks of development and family planning lies in promoting the main message to a wider national and international audience

    2007-01-01

    Full Text Available In recent years, mobile devices have become relatively more powerful with additional features which have the capability to provide multimedia streaming. Better, faster and more reliable data storage solutions in the mobile messaging platform have become more essential with these additional improvements. The existing mobile messaging infrastructure, in particular the data storage platform has become less proficient in coping with the increased demand for its services. This demand especially in the mobile messaging area (i.e. SMS – Short Messaging Service, MMS – Multimedia Messaging Service, which may well exceeded 250,000 requests per second, means that the need to evaluate competing data management systems has become not only necessary but essential. This paper presents an evaluation of SMS and MMS platforms using different database management systems – DBMS and recommends the best data management strategies for these platforms.

  13. Secure Media Independent Handover Message Transport in Heterogeneous Networks

    Directory of Open Access Journals (Sweden)

    Cho Choong-Ho

    2009-01-01

    Full Text Available The IEEE 802.21 framework for Media Independent Handover (MIH provides seamless vertical handover support for multimode mobile terminals. MIH messages are exchanged over various wireless media between mobile terminals and access networks to facilitate seamless handover. This calls for the need to secure MIH messages against network security threats in the wireless medium. In this paper, we first analyze IPSec/IKEv2 and DTLS security solution for secure MIH message transport. We show that handover latency can be an impediment to the use of IPSec and DTLS solutions. To overcome the handover overhead and hence minimize authentication time, a new secure MIH message transport solution, referred as MIHSec in this paper, is proposed. Experimental results are obtained for MIH between WLAN and Ethernet networks and the impacts of MIH message security on the handover latency are evaluated for IPSec, DTLS, and MIHSec security solutions. The effectiveness of MIHSec is demonstrated.

    2014-01-01

    Full Text Available The transport message security provided by vehicles in VANETs is quite important; vehicle message should be real-time and it will be not complicated to validate message calculation. The method proposed in the essay is mainly to validate the identity by means of Bilinear Diffie-Hellman method, and make vehicles validate the authenticity of RSU and TA’s identity and the effectiveness of key. RSU and TA only need to validate vehicle identity, without helping vehicles produce any key. When vehicle identity validation is completed, vehicles will produce public value and transmit it to other RSU and vehicles, while other vehicles could validate the identity through the message from the sender and public value from RSU. The advantages of the method proposed in this essay are listed as follows. (1 Vehicles, RSU, and TA can validate mutual identities and the effectiveness of keys. (2 Vehicles can produce public value functions automatically, thus reducing key control risks. (3 Vehicles do not need to show certificates to validate their identities, preventing the certificates from attacking because of long-term exposure. (4 Vehicles adopt a pseudonym ID challenge to validate their own identities during the process of handoff. (5 Vehicle messages can be validated using the Bilinear Diffie-Hellman (BDH method without waiting for the RSU to validate messages, thus improving the instantaneity of messaging. The method proposed in the essay can satisfy source authentication, message integrity, nonrepudiation, privacy, and conditional untraceability requirements.

    Full Text Available During the past few years, there have been growing interests in using email for delivering various types of messages such as social, financial, etc. There are also people who use email messages to promote products and services or even to do criminal activities called Spam email. These unwanted messages are sent to different target population for different purposes and there is a growing interest to develop methods to filter such email messages. This paper presents a method to filter Spam email messages based on the keyword pattern. In this article, a multi-agent filter trade based on the Bayes rule, which has benefit of using the users’ interest, keywords and investigation the message content according to its topic, has been used. Then Nested Neural Network has been used to detect the spam messages. To check the authenticity of this proposed method, we test it for a couple of email messages, so that it could determine spams and hams from each other, effectively. The result shows the superiority of this method over the previous ones including filters with Multi-Layer Perceptron that detect spams.

    The frequency of screening for HIV and other sexually transmitted infections (STIs) among men who have sex with men (MSM) is still low in China. A sexual health clinic based randomised controlled trial will be conducted in Guangzhou, Wuxi and Shenzhen, China, enrolling 600 MSM. Eligibility will be judged by the pre-programed iPad based questionnaire: (1) age ≥18 years and (2) have had two or more male anal sex partners, or condomless anal sex with a casual male sex partner, or an STI history, in the past 6 months, and (3) provides a valid mobile phone number. Eligible men will be randomly allocated 1:1 to the intervention arm (with monthly text messages reminding them to test for HIV/STIs) or to the control arm (with no reminders). Men in both arms will complete a questionnaire onsite at enrolment and after 12 months, and another questionnaire online at 6 months. Men in both arms will be tested for HIV, syphilis, anal gonorrhoea/chlamydia and penile gonorrhoea/chlamydia at enrolment and at 12 months. The primary outcome is the rate and frequency of HIV testing within the 12 months after enrolment. The secondary outcome is the rate of unprotected anal intercourse. An assessment of the cost effectiveness of this intervention is also planned. The study has been approved by the ethical review committees of the University of New South Wales, Australia (HC16803), the Guangdong Provincial Centre for Skin Disease and STI Control (GDDHLS-20160926) and the Wuxi Centre for Disease Control and Prevention (WXCDC2016009), China.

  18. A Message Without a Code?

    Directory of Open Access Journals (Sweden)

    Tom Conley

    1981-01-01

    Full Text Available The photographic paradox is said to be that of a message without a code, a communication lacking a relay or gap essential to the process of communication. Tracing the recurrence of Barthes's definition in the essays included in Image/Music/Text and in La Chambre claire , this paper argues that Barthes's definition is platonic in its will to dematerialize the troubling — graphic — immediacy of the photograph. He writes of the image in order to flee its signature. As a function of media, his categories are written in order to be insufficient and inadequate; to maintain an ineluctable difference between language heard and letters seen; to protect an idiom of loss which the photograph disallows. The article studies the strategies of his definition in «The Photographic Paradox» as instrument of abstraction, opposes the notion of code, in an aural sense, to audio-visual markers of closed relay in advertising, and critiques the layout and order of La Chambre claire in respect to Barthes's ideology of absence.

    To study the impact on adolescent immunization rates of direct messages to parents/guardians. Electronic health record rules identified adolescents needing an immunization. Parents/guardians of adolescents were messaged via a single vendor using automated text, prerecorded voice, and/or postcard. Parents/guardians of 3,393 patients, ages 11-18 years, with one or more primary care visits in the prior 2 years, identified as needing (average of 2.04 years) a vaccination (meningococcal conjugate, human papillomavirus, or tetanus, diphtheria, and pertussis vaccines) were messaged (mean age, 14 years; 50% male; 38% African-American; 23% white; 19% Hispanic; and 79% public health insurance). A total of 7,094 messages were sent: 3,334 automated voice (47%), 2,631 texts (37%), and 1,129 postcards (16%). After the first message, 865 adolescents (25.5%) received at least one vaccine. Within 24 weeks of messaging 1,324 vaccines (745 human papillomavirus; 403 meningococcal conjugate; and 176 tetanus, diphtheria, and pertussis vaccines) occurred in 959 visits (83.8% physician visits and 16.2% nurse visits). Average visits generated $204 gross reimbursement for $1.77 in messaging expenses per vaccine given. No differences in immunization completion rates occurred by age, gender, race/ethnicity, or insurance type. At 24 weeks, one message was more effective than two or three messages (35.6%, 19.4%, and 24.1% effectiveness, respectively; p adolescents needing vaccination and required minimal financial expenditure.

    Full Text Available This paper presented a fundamental framework for Changeable Message Sign (CMS placement design along roadways with horizontal curves. This analytical framework determines the available distance for motorists to read and react to CMS messages based on CMS character height, driver's cone of vision, CMS pixel's cone of legibility, roadway horizontal curve radius, and CMS lateral and vertical placement. Sample design charts were developed to illustrate how the analytical framework may facilitate CMS placement design.

  3. Diffusion of Messages from an Electronic Cigarette Brand to Potential Users through Twitter.

    Full Text Available This study explores the presence and actions of an electronic cigarette (e-cigarette brand, Blu, on Twitter to observe how marketing messages are sent and diffused through the retweet (i.e., message forwarding functionality. Retweet networks enable messages to reach additional Twitter users beyond the sender's local network. We follow messages from their origin through multiple retweets to identify which messages have more reach, and the different users who are exposed.We collected three months of publicly available data from Twitter. A combination of techniques in social network analysis and content analysis were applied to determine the various networks of users who are exposed to e-cigarette messages and how the retweet network can affect which messages spread.The Blu retweet network expanded during the study period. Analysis of user profiles combined with network cluster analysis showed that messages of certain topics were only circulated within a community of e-cigarette supporters, while other topics spread further, reaching more general Twitter users who may not support or use e-cigarettes.Retweet networks can serve as proxy filters for marketing messages, as Twitter users decide which messages they will continue to diffuse among their followers. As certain e-cigarette messages extend beyond their point of origin, the audience being exposed expands beyond the e-cigarette community. Potential implications for health education campaigns include utilizing Twitter and targeting important gatekeepers or hubs that would maximize message diffusion.

    Dual task experiments have highlighted that driving while having a conversation on a cell phone can have negative impacts on driving (Strayer & Drews, 2007). It has also been noted that this negative impact is greater when reading a text-message (Lee, 2007). Commonly used in text-messaging are shortening devices collectively known as text-speak (e.g.,Ys I wll ttyl 2nite, Yes I will talk to you later tonight). To the authors' knowledge, there has been no investigation into the potential negative impacts of reading text-speak on concurrent performance on other tasks. Forty participants read a correctly spelled story and a story presented in text-speak while concurrently monitoring for a vibration around their waist. Slower reaction times and fewer correct vibration detections occurred while reading text-speak than while reading a correctly spelled story. The results suggest that reading text-speak imposes greater cognitive load than reading correctly spelled text. These findings suggest that the negative impact of text messaging on driving may be compounded by the messages being in text-speak, instead of orthographically correct text.

    Full Text Available Audiovisual programs are meant to be seen and heard simultaneously. Screen translators have to take the verbal, acoustic and visual elements of audiovisual works into consideration. However they translate only the verbal content of the message. In the following article we focus on one of the main modalities for audiovisual translation, namely the subtitling. Our aim is to describe the specificity of screen translation and to think about the impact of subtitling process on the final product, that is on translation. We will show how translators take advantage of the presence of the verbal (dialogues and the visual (screen codes with the aim of reducing an original text.

    2016-06-01

    Full Text Available Message passing is widely used in industry to develop programs consisting of several distributed communicating components. Developing functionally correct message passing software is very challenging due to the concurrent nature of message exchanges. Nonetheless, many safety-critical applications rely on the message passing paradigm, including air traffic control systems and emergency services, which makes proving their correctness crucial. We focus on the modular verification of MPI programs by statically verifying concrete Java code. We use separation logic to reason about local correctness and define abstractions of the communication protocol in the process algebra used by mCRL2. We call these abstractions futures as they predict how components will interact during program execution. We establish a provable link between futures and program code and analyse the abstract futures via model checking to prove global correctness. Finally, we verify a leader election protocol to demonstrate our approach.

    2017-09-15

    After the development of the first phone at the end of 19th century, communication technologies took a great leap forward in the 20th century. With the birth of the "smartphone" in the 21st century, communication technologies exponentially evolved and became an important part of our daily routine. Effective communications between clinicians is critical in medical care and miscommunications are a source of errors. Although telecommunication technologies have proliferated dramatically in the last decade, there is scarce evidence-based information on the use of this technology in medical care. For the purposes of medical communication, we can now consult each other about patients individually and within a group via instant messaging applications by using text messages, photos, audio messages and even videos. In this review, we examine the uses and drawbacks of instant messaging applications in medical communications.

  11. Quantifying regional differences in the length of Twitter messages.

    Directory of Open Access Journals (Sweden)

    Christian M Alis

    Full Text Available The increasing usage of social media for conversations, together with the availability of its data to researchers, provides an opportunity to study human conversations on a large scale. Twitter, which allows its users to post messages of up to a limit of 140 characters, is one such social media. Previous studies of utterances in books, movies and Twitter have shown that most of these utterances, when transcribed, are much shorter than 140 characters. Furthermore, the median length of Twitter messages was found to vary across US states. Here, we investigate whether the length of Twitter messages varies across different regions in the UK. We find that the median message length, depending on grouping, can differ by up to 2 characters.

    Abstract Instant Messaging communication services provide a variety of communication features that can be used by the user, such as text messaging (text messages both online and offline. One of the standard protocol that supports this service is XMPP (Extensible Messaging and Presence Protocol. XMPP communication using XML documents, making it vulnerable to passive attacks monitoring content of  communications. To overcome this drawback the solution is encrypted communications. The other solutions that try to offer in this research is the use of a covert channel to send hidden messages. In this research will create a browser based XMPP client application that is capable to deliver XMPP communication and also provide covert channel communication. XMPP communication can be built on a web-based application using WebSocket protocol. This protocol will exploit field masking-key to load the covert channel messages that is sent during the session XMPP communication takes place. From the test results, the client application is able to produce a covert channel communication with a data width of 3 bytes in each packet. The client application is also able to perform covert communication channel in a communication link with the condition of the probability of packet loss rate below 10%.   Keywords— WebSocket, XMPP, masking-key, Covert Channel, browser based application.

    Spurred in part by world-wide interest in improving warning messaging for and response to tsunamis in the wake of several catastrophic tsunamis since 2004 and growing interest at the US National Weather Service (NWS) to integrate social science into their Tsunami Program, the NWS Tsunami Warning Centers in Alaska and Hawaii have made great progress toward enhancing tsunami messages. These include numerous products, among them being Tsunami Warnings, Tsunami Advisories and Tsunami Watches. Beginning in 2010 we have worked with US National Tsunami Hazard Mitigation Program (NTHMP) Warning Coordination and Mitigation and Education Subcommittee members; Tsunami Program administrators; and NWS Weather Forecast Officers to conduct a series of focus group meetings with stakeholders in coastal areas of Alaska, American Samoa, California, Hawaii, North Carolina, Oregon, US Virgin Islands and Washington to understand end-user perceptions of existing messages and their existing needs in message products. We also reviewed research literature on behavioral response to warnings to develop a Tsunami Warning Message Metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order, Formatting, and Receiver Characteristics. A sample message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met, whether the message is a full length or short message. Incrementally, this work contributed to revisions in the format, content and style of message products issued by the National Tsunami Warning Center (NTWC). Since that time, interest in short warning messages has continued to increase and in May 2016 the NTWC began efforts to revise message products to take advantage of recent NWS policy changes allowing use of mixed-case text

    In this paper we present the concept of MPF, Message Passing Fluid, an abstract fluid where the molecules move by mean of the informations that they exchange each other, on the basis of rules and methods of a generalized Cellular Automaton. The model is intended for a simulation by mean of message passing libraries on the field of parallel computing, which seems to offer a natural environment for this subject. The first results show that by mean of simple mathematical models it's possible to obtain realistic simulations of fluid motion, in the case of a general geometry too.

Since the Arecibo message of 1974, the handful of METI broadcasts have increased in content and complexity, but the lack of an established protocol has produced unorganized or cryptic messages that could be difficult to interpret. Here we outline the development of a self-consistent protocol for messaging to extraterrestrial intelligence that provides constraints and guidelines for the construction of a message in order to maximize the probability that the message effectively communicates. A METI protocol considers several factors including signal encoding, message length, information content, anthropocentrism, transmission method, and transmission periodicity. Once developed, the protocol will be released for testing on different human groups worldwide and across cultural boundaries. An effective message to extraterrestrials should at least be understandable ...

  18. Addressing medication nonadherence by mobile phone: development and delivery of tailored messages.

    2014-01-01

    Medication nonadherence remains a significant public health problem, and efforts to improve adherence have shown only limited impact. The tailoring of messages has become a popular method of developing communication to influence specific health-related behaviors but the development and impact of tailored text messages on medication use is poorly understood. The aim of this paper is to describe an approach to developing theory-based tailored messages for delivery via mobile phone to improve medication adherence among patients with diabetes. Kreuter's five-step tailoring process was followed to create tailored messages for mobile phone delivery. Two focus group sessions, using input from 11 people, and expert review of message content were used to adapt the survey instrument on which the messages were tailored and edit the developed messages for the target population. Following established tailoring methods a library of 168 theory-driven and 128 medication-specific tailored messages were developed and formatted for automated delivery to mobile phones. Concepts from the Health Belief Model and Self-Determination Theory were used to craft the messages and an algorithm was applied to determine the order and timing of messages with the aim of progressively influencing disease and treatment-related beliefs driving adherence to diabetes medication. The process described may be applied to future investigations aiming to improve medication adherence in patients with diabetes and the effectiveness of the current messages will be tested in a planned analysis.

    Cvjetićanin Tijana

    2006-01-01

    Full Text Available The development of ICT media made way for a new form of folklore communication. Newly developed media, such as mobile phones, make it possible for their users to participate in electronically mediated communication, thus approaching the form of oral communication. The exchange of special type of SMS text messages represents a new way of transmitting contemporary folklore short forms. These messages use poetic language, they have standard style themes, patterns and formulas, and they form different genres and categories corresponding with already existing familiar folklore forms. The communication process that happens during the exchange of these messages also has folklore’s characteristics: it takes place within small groups, the communication is informal, the texts circulate in chain style, and undergo different transformation which generates the making of variants, etc. This form of electronic folklore is especially popular among teenagers, where it’s social functions and meanings are also most emphasized. Within this population, it adds to an older tradition of children’s written folklore poetry albums. Like poetry albums, SMS exchange influences the development of girls’ gender identity, providing also a socially defined channel for contacts between the sexes. It also functions as a mechanism of socialization and stratification within the group. At the same time, it creates a new field of meaning, which derives from the very media’s novelty and significance. In this sense, the exchange of SMS represents a symbolic act of acknowledging one’s belonging to the group of mobile telephone users. In this way, a new phenomenon is being symbolically processed through a new form of folklore.

    Full Text Available We present PolySing#, a calculus that models process interaction based on copyless message passing, in the style of Singularity OS. We equip the calculus with a type system that accommodates polymorphic endpoint types, which are a variant of polymorphic session types, and we show that well-typed processes are free from faults, leaks, and communication errors. The type system is essentially linear, although linearity alone may leave room for scenarios where well-typed processes leak memory. We identify a condition on endpoint types that prevents these leaks from occurring.

    Sontag, Jennah M; Noar, Seth M

    2017-04-01

    The recent Surgeon General's call-to-action to prevent skin cancer indicates an urgent need for research on messages to deter young women from tanning indoors. Answering this call, the current study assessed differences in the potential effectiveness of pictorial indoor tanning messages. We randomly assigned undergraduate female participants (N = 568) to one of three message conditions visually depicting health effects, appearance damage, or immediate risks, or to a text-only control. All participants viewed three messages within their condition and answered questions after message exposure. Factorial ANOVAs indicated that compared to the text-only condition, pictorial messages produced greater negative emotional reactions and were perceived as more effective than text-only messages. Text-only messages, however, were significantly more believable than pictorial messages. We observed several differences among the pictorial conditions and among the messages within the pictorial conditions. We conclude that messages discouraging indoor tanning should use pictorial messages illustrating the negative health and appearance damaging effects of indoor tanning, focusing on particular health and appearance consequences. Additional research is needed to guide the selection of images that are believable and will most discourage indoor tanning behavior.

    This paper concerns a modified approach of compressing Short Bengali Text Message for small devices. The prime objective of this research technique is to establish a low complexity compression scheme suitable for small devices having small memory and relatively lower processing speed. The basic aim is not to compress text of any size up to its maximum level without having any constraint on space and time, rather than the main target is to compress short messages up to an optimal level which needs minimum space, consume less time and the processor requirement is lower. We have implemented Character Masking, Dictionary Matching, Associative rule of data mining and Hyphenation algorithm for syllable based compression in hierarchical steps to achieve low complexity lossless compression of text message for any mobile devices. The scheme to choose the diagrams are performed on the basis of extensive statistical model and the static Huffman coding is done through the same context.

    Full Text Available What keeps us from becoming what we can be? Renaissance genius Michelangelo’s ideas about crafting sculpture are a powerful metaphor for the release of our hidden performance potential. The actualizations of inherent potential can be viewed as a creative work performance that synergizes head, heart, and body. Potential is seen as being closely related to the psychological concepts of talents and multiple intelligences.   For the global economy, the effective employment of talent, intelligence, and knowledge is projected to be a primary driving force for years to come. For business organizations, investment in the realization of human potential is seen to have lasting value and is considered to be a continuing source of competitive advantage. For the Arts and Humanities, the constructive realization of human potential has been a long-pursued Holy Grail. And, for the individual, there is the real possibility of enhanced future performance with an associated economic payoff.

    As scholars involved with the Search for Extraterrestrial Intelligence (SETI) have contemplated how we might portray humankind in any messages sent to civilizations beyond Earth, one of the challenges they face is adequately representing the diversity of human cultures. For example, in a 2003 workshop in Paris sponsored by the SETI Institute, the International Academy of Astronautics (IAA) SETI Permanent Study Group, the International Society for the Arts, Sciences and Technology (ISAST), and the John Templeton Foundation, a varied group of artists, scientists, and scholars from the humanities considered how to encode notions of altruism in interstellar messages art_science/2003>. Though the group represented 10 countries, most were from Europe and North America, leading to the group's recommendation that subsequent discussions on the topic should include more globally representative perspectives. As a result, the IAA Study Group on Interstellar Message Construction and the SETI Institute sponsored a follow-up workshop in Santa Fe, New Mexico, USA in February 2005. The Santa Fe workshop brought together scholars from a range of disciplines including anthropology, archaeology, chemistry, communication science, philosophy, and psychology. Participants included scholars familiar with interstellar message design as well as specialists in cross-cultural research who had participated in the Symposium on Altruism in Cross-cultural Perspective, held just prior to the workshop during the annual conference of the Society for Cross-cultural Research . The workshop included discussion of how cultural understandings of altruism can complement and critique the more biologically based models of altruism proposed for interstellar messages at the 2003 Paris workshop. This paper, written by the chair of both the Paris and Santa Fe workshops, will explore the challenges of communicating concepts of altruism that draw on both biological and cultural models.

    Full Text Available This paper tries to analyse the conditions of emerging of text linguistics, taking into consideration the rootsof the preoccupations in its domain, originated in the framework of the communication studies. Thus, the change ofthe perspective on communication, from the mechanistic transmission to interactivity and the exchange of themeanings, led to the pragmatic orientation of the linguistic researches, not just to the message itself, but also to theelements of the communicative act and to the context where the exchange of the meanings takes place. As a result,text linguistics defines the text as communicational occurrence, involving both the members of the communicationand the conditions of the production and the reception of the message, unlike conventional linguistics which studiesthe text in abstracto, just the message itself, ignoring the world that the text refers to, or the users of the message, thetransmitter and the receiver.

Correct resolution is made even more difficult when there is little context to determine which place is intended, as in a 140-character Twitter message, or when location cues from different sources conflict, as may be the case among different metadata fields of a Twitter message. We used supervised machine learning to weigh the different fields of the Twitter message and the features of a world gazetteer to create a model that will prefer the correct gazetteer candidate to resolve the extracted expression. We evaluated our model using the F1 measure and compared it to similar algorithms. Our method achieved results higher than state-of-the-art competitors.

    -planned subgroup analyses based on the type of message (screening, prevention, and treatment). The primary outcome was behaviour. We did not assess any adverse outcomes. We included 35 studies involving 16,342 participants (all health consumers) and reporting 51 comparisons.In the context of attribute framing, participants in one included study understood the message better when it was framed negatively than when it was framed positively (1 study; SMD -0.58 (95% confidence interval (CI) -0.94 to -0.22); moderate effect size; low quality evidence). Although positively-framed messages may have led to more positive perception of effectiveness than negatively-framed messages (2 studies; SMD 0.36 (95% CI -0.13 to 0.85); small effect size; low quality evidence), there was little or no difference in persuasiveness (11 studies; SMD 0.07 (95% CI -0.23 to 0.37); low quality evidence) and behavior (1 study; SMD 0.09 (95% CI -0.14 to 0.31); moderate quality evidence).In the context of goal framing, loss messages led to a more positive perception of effectiveness compared to gain messages for screening messages (5 studies; SMD -0.30 (95% CI -0.49 to -0.10); small effect size; moderate quality evidence) and may have been more persuasive for treatment messages (3 studies; SMD -0.50 (95% CI -1.04 to 0.04); moderate effect size; very low quality evidence). There was little or no difference in behavior (16 studies; SMD -0.06 (95% CI -0.15 to 0.03); low quality evidence). No study assessed the effect on understanding. Contrary to commonly held beliefs, the available low to moderate quality evidence suggests that both attribute and goal framing may have little if any consistent effect on health consumers' behaviour. The unexplained heterogeneity between studies suggests the possibility of a framing effect under specific conditions. Future research needs to investigate these conditions.

    Full Text Available Introduction Research suggests that electronic messaging can improve patient engagement. Studies indicate that a ‘digital divide’ may exist, where certain patient populations may be using electronic messaging less frequently. This study aims to determine which patient characteristics are associated with different levels of usage of an electronic patient-provider messaging system in a diverse urban population.Methods Cross-sectional electronic health record data were extracted for patients 10 years of age or older who live in New York City and who visited a set of clinics between 1 July 2011 and 30 June 2012. Regression analyses determined which participant characteristics were associated with the sending of electronic messages.Results Older, female, English-speaking participants of white race who received more messages, had any diagnoses, more office visits and a provider who sent messages were more likely to send more messages. Non-Millennial, non-white participants who received fewer messages, had more office visits, any diagnoses, a provider who saw fewer patients with patient portal accounts, lived in a low socioeconomic status neighbourhood, and did not have private insurance were more likely to send zero messages.Conclusion This study found significant differences in electronic messaging usage based on demographic, socioeconomic and health-related patient characteristics. Future studies are needed to support these results and determine the causes of observed associations.

    Full Text Available The assumption that snacks could cause problem in diet and bodyweight, makes this study interesting. Because this product, Fitbar, appears on the market as a healthy snack that is contrary to this assumption. This product is about to prove that there is a healthy and tasty snack as snacks. Marketing communications through advertising billboards with the media aims to reach the target market. Fitbar billboard ads convey the message content in the form of information about the attributes and benefits of products such as nutritional content and product slogans. This study uses path analysis techniques to determine the effect of variable X (advertisement message to variable Y (brand awareness and its implications on the variable Z (brand image. The results showed that the content of the message components such as message structure, message display, message format, and the source of the message have contributed in the formation of brand awareness, which further on has implications on brand image. Influence on brand awareness message content is equal to 0.609. The effect of variable X (message and Y (brand awareness to variable Z (brand image amounted to 0,365. Therefore, the use of billboards media in conveying the message to the target market of Fitbar products is to build brand awareness and the implications for brand image.

    Instant messaging (IM) is when users communicate instantly via their mobile devices, and it has become one of the most preferred choices of tools to communicate amongst health professions students. The aim of this study was to understand how dental students communicate via IM, faculty members' perspectives on using IM to communicate with students, and whether such tools are useful in the learning environment. After free-associating themes on online communication, two draft topic guides for structured interviews were designed that focussed on mobile device-related communication activities. A total of 20 students and six faculty members at the University of Birmingham School of Dentistry agreed to take part in the interviews. Students were selected from years 1-5 representing each year group. The most preferred communication tools were emails, social networking, and IM. Emails were used for more formal messages, and IM and social networking sites were used for shorter messages. WhatsApp was the most used IM app because of its popular features such as being able to check if recipients have read and received messages and group work. The students reported that changes were necessary to improve their communication with faculty members. The faculty members reported having mixed feelings toward the use of IM to communicate with students. The students wished to make such tools a permanent part of their learning environment, but only with the approval of faculty members. The faculty members were willing to accept IM as a communication tool only if it is monitored and maintained by the university and has a positive effect on learning.

    Information, education, and communication (IEC) programs need to be strengthened to appeal to adolescents, who are increasingly contributing to unwanted pregnancy and are using abortion as a means of birth control. Successful IEC programs have the following characteristics: 1) established communication theories that guide development of materials; 2) a multimedia and a mass media approach to information dissemination, and 3) emphasis on visual displays. The primary emphasis should be on presentation of a concise, clear message with the appropriate visual medium. Many communication specialists in developing countries, however, lack the training to design and use effective IEC software. Designing effective messages involves a process of integrating scientific ideas with artistic appeal. The aim is to stimulate the target audience to change its behavior of life style. The message must be convincing and contain practical and useful information. The IEC Software Design Cycle focuses on analysis and diagnosis, design production, pretesting and modification, and distribution and evaluation. Each of these processes are described. Necessary before any attempt is made is obtaining data on historical, sociocultural, and demographic characteristics, economic activities, health and social services, communication infrastructure, marriage and family life patterns, and decision making systems. Focus group discussions may be used to collect information about the target group. An example is given of the process of development, in a course through the Center or African Family Studies, of a poster about premarital sex directed to 11-16 year olds. On the basis of focus group discussions, it was decided that the message would be to encourage girls to talk with their mothers about family life and premarital sex. The poster was produced with 2 school girls talking in front of the school. The evaluation yielded modifications such as including a school building that resembled actual

    Full Text Available The given piece of work „Utterer. Receiver. Literary text”, sets to exemplify/illustrate the fact thatliterature is similar to a communication act. The writer, as the author of a message, becomes utterer, and thecode he uses is the artistic language. The reader becomes the receiver of this message through reading, seen as„a process of revealing the meanings”.Afterwards we wanted to puzzle out „the message” of the novel „Miss Romania” by Cezar Petrescu,following several levels of representation: denotation, connotation, myths, symbols.Literature is, therefore, an artistic process of communication between the creator and the receiver.

    review author. Study design features, characteristics of target populations, interventions and controls, and results data were extracted by two review authors and confirmed by a third author. Two authors assessed the risk of bias of the included studies. As the intervention characteristics and outcome measures were similar across included studies, we conducted a meta-analysis to estimate an overall effect size. We included eight randomised controlled trials involving 6615 participants. Four of these studies were newly identified during this update.We found moderate quality evidence from seven studies (5841 participants) that mobile text message reminders improved the rate of attendance at healthcare appointments compared to no reminders (risk ratio (RR) 1.14 (95% confidence interval (CI) 1.03 to 1.26)). There was also moderate quality evidence from three studies (2509 participants) that mobile text message reminders had a similar impact to phone call reminders (RR 0.99 (95% CI 0.95 to 1.02). Low quality evidence from one study (291 participants) suggests that mobile text message reminders combined with postal reminders improved the rate of attendance at healthcare appointments compared to postal reminders alone (RR 1.10 (95% CI 1.02 to 1.19)). Overall, the attendance to appointment rates were 67.8% for the no reminders group, 78.6% for the mobile phone messaging reminders group and 80.3% for the phone call reminders group. One study reported generally that there were no adverse effects during the study period; none of the studies reported in detail on specific adverse events such as loss of privacy, data misinterpretation, or message delivery failure. Two studies reported that the costs per text message per attendance were respectively 55% and 65% lower than costs per phone call reminder. The studies included in the review did not report on health outcomes or people's perceptions of safety related to receiving reminders by text message. Low to moderate quality evidence

  4. A Novel Approach for Arabic Text Steganography Based on the “BloodGroup” Text Hiding Method

    2017-04-01

    Full Text Available Steganography is the science of hiding certain messages (data in groups of irrelevant data possibly of other form. The purpose of steganography is covert communication to hide the existence of a message from an intermediary. Text Steganography is the process of embedding secret message (text in another text (cover text so that the existence of secret message cannot be detected by a third party. This paper presents a novel approach for text steganography using the Blood Group (BG method based on the behavior of blood group. Experimentally it is found that the proposed method got good results in capacity, hiding capacity, time complexity, robustness, visibility, and similarity which shows its superiority as compared to most several existing methods.

    2014-04-01

    Full Text Available This article presents the Concepts Network tool, developed using text mining technology. The main objective of this tool is to extract and relate terms of greatest incidence from a text and exhibit the results in the form of a graph. The Network was implemented in the Collective Text Editor (CTE which is an online tool that allows the production of texts in synchronized or non-synchronized forms. This article describes the application of the Network both in texts produced collectively and texts produced in a forum. The purpose of the tool is to offer support to the teacher in managing the high volume of data generated in the process of interaction amongst students and in the construction of the text. Specifically, the aim is to facilitate the teacher’s job by allowing him/her to process data in a shorter time than is currently demanded. The results suggest that the Concepts Network can aid the teacher, as it provides indicators of the quality of the text produced. Moreover, messages posted in forums can be analyzed without their content necessarily having to be pre-read.

  7. Asynchronous Message Service Reference Implementation

    Burleigh, Scott C.

    2011-01-01

    This software provides a library of middleware functions with a simple application programming interface, enabling implementation of distributed applications in conformance with the CCSDS AMS (Consultative Committee for Space Data Systems Asynchronous Message Service) specification. The AMS service, and its protocols, implement an architectural concept under which the modules of mission systems may be designed as if they were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating. Communication relationships among such modules are self-configuring; this tends to minimize complexity in the development and operations of modular data systems. A system built on this model is a society of generally autonomous, inter-operating modules that may fluctuate freely over time in response to changing mission objectives, modules functional upgrades, and recovery from individual module failure. The purpose of AMS, then, is to reduce mission cost and risk by providing standard, reusable infrastructure for the exchange of information among data system modules in a manner that is simple to use, highly automated, flexible, robust, scalable, and efficient. The implementation is designed to spawn multiple threads of AMS functionality under the control of an AMS application program. These threads enable all members of an AMS-based, distributed application to discover one another in real time, subscribe to messages on specific topics, and to publish messages on specific topics. The query/reply (client/server) communication model is also supported. Message exchange is optionally subject to encryption (to support confidentiality) and authorization. Fault tolerance measures in the discovery protocol minimize the likelihood of overall application failure due to any single operational error anywhere in the system. The multi-threaded design simplifies processing while enabling application nodes to

  8. Persuasive Populism? Estimating the Effect of Populist Messages on Political Cynicism

    Directory of Open Access Journals (Sweden)

    Matthijs Rooduijn

    2017-12-01

    Full Text Available Many European countries have seen a growth of populism in recent years. Extant research shows that populist parties are increasingly successful, and that populist messages appear more frequently in the media. This raises the question to what extent populist messages affect public opinion. The aim of this study is to assess whether populist messages fuel political cynicism by arguing that an arrogant, selfish and complacent political elite does not listen to what ordinary people find important. Moreover, it assesses whether populist messages affect only those already favourably predisposed towards populist parties, or whether it affects citizens across the board. The results of a survey experiment, conducted in the Netherlands, suggests that individuals who are exposed to populist messages are indeed more cynical afterwards than individuals who are exposed to a very similar, but more ‘neutrally formulated’ message. However, the effects seem to be restricted to supporters of populist parties.

    Full Text Available Exchange of information through cyberspace has many benefits as an example fast estimated time, unlimited physical distance and space limits, etc. But in these activities can also pose a security risk for confidential information. It is necessary for the safety that can be used to protect data transmitted through the Internet. Encryption algorithm that used to encrypt message to be sent (plaintext into messages that have been randomized (ciphertext is cryptography and steganography algorithms. In application of cryptographic techniques that will be used is Hill Cipher. The technique is combined with steganography techniques Least Significant Bit. The result of merging techniques can maintain the confidentiality of messages because people who do not know the secret key used will be difficult to get the message contained in the stego-image and the image that has been inserted can not be used as a cover image. Message successfully inserted and extracted back on all samples with a good image formats * .bmp, * .png , * .jpg at a resolution of 512 x 512 pixels , 256 x 256 pixels. MSE and PSNR results are not influenced file format or file size, but influenced by dimensions of image. The larger dimensions of the image, then the smaller MSE that means error of image gets smaller.

  18. Songs as a Medium for Embedded Reproductive Messages

    Directory of Open Access Journals (Sweden)

    Dawn R. Hobbs

    2011-07-01

    Full Text Available Research shows that sensational news stories as well as popular romance novels often feature themes related to important topics in evolutionary psychology. In the first of four studies described in this paper we examined the song lyrics from three Billboard charts: Country, Pop, and R&B. A content analysis of the lyrics revealed 18 reproductive themes that read like an outline for a course in evolutionary psychology. Approximately 92% of the 174 songs that made it into the Top Ten in 2009 contained one or more reproductive messages, with an average of 10.49 reproductive phrases per song. Although differences in the frequency of different themes between charts were found, further analyses showed that the most popular/bestselling songs contained significantly more reproductive messages. An analysis of the lyrics of opera arias and art songs also revealed evidence for many of the same embedded reproductive messages extending back more than 400 years.

  19. What it Takes to Get Passed On: Message Content, Style, and Structure as Predictors of Retransmission in the Boston Marathon Bombing Response.

    Directory of Open Access Journals (Sweden)

    Jeannette Sutton

    Full Text Available Message retransmission is a central aspect of information diffusion. In a disaster context, the passing on of official warning messages by members of the public also serves as a behavioral indicator of message salience, suggesting that particular messages are (or are not perceived by the public to be both noteworthy and valuable enough to share with others. This study provides the first examination of terse message retransmission of official warning messages in response to a domestic terrorist attack, the Boston Marathon Bombing in 2013. Using messages posted from public officials' Twitter accounts that were active during the period of the Boston Marathon bombing and manhunt, we examine the features of messages that are associated with their retransmission. We focus on message content, style, and structure, as well as the networked relationships of message senders to answer the question: what characteristics of a terse message sent under conditions of imminent threat predict its retransmission among members of the public? We employ a negative binomial model to examine how message characteristics affect message retransmission. We find that, rather than any single effect dominating the process, retransmission of official Tweets during the Boston bombing response was jointly influenced by various message content, style, and sender characteristics. These findings suggest the need for more work that investigates impact of multiple factors on the allocation of attention and on message retransmission during hazard events.

    2016-12-01

    Depression is highly prevalent among college students. Although treatment is often available on university campuses, many stigma-based barriers prevent students from seeking help. Communication strategies, such as the use of metaphors, are needed to reduce barriers. Specially, the use of visual metaphors, as a strategic message design tactic, may be an effective communication strategy to increase message appeal and engagement. Using a 2-phase approach, this study first identified common metaphors students use to conceptualize mental illness. Messages incorporating conceptual and visual metaphors were then designed and tested to determine their potential in reducing stigma. Participants (n = 256) were randomly assigned to 1 of 4 conditions in a between-subjects experiment: messages with visual and textual metaphors, messages with straightforward visuals and textual metaphors, text-based metaphor messages, or a control group. Overall, metaphorical messages are appealing, the use of visual metaphors leads to greater message engagement, and messages based on conceptual metaphors have the potential to reduce stigma. The use of conceptual and visual metaphors in campaign design is an effective strategy to communicate about a complex health topic, such as mental illness, and should be considered for use in campaigns to reduce barriers for help-seeking behavior.

  3. The effects of matching a persuasive message to a recipient's self-concept on attitude change

    Directory of Open Access Journals (Sweden)

    Branković Marija

    2010-01-01

    Full Text Available The paper addresses the question of whether matching a persuasive message to a recipient's self-concept can enhance message processing. A large body of experiments within the Elaboration likelihood model proved that framing a message so as to be perceived as selfrelevant led to more careful argument scrutiny. In this research, we matched the messages with previously assessed need for cognition - tendency to engage in and enjoy effortful cognitive tasks. Two possible sources of motivation to process a persuasive message were hereby confronted: dispositional (cognitive style and situational (matching. Results showed a significant attitude change, but the main hypothesis was not confirmed: matched messages did not produce more argument processing activity than the mismatched. Manipulations did not have any significant effects on message processing of the high need for cognition participants. Contrary to expectations, participants low in their need for cognition elaborated the message more carefully when it was mismatched, that is when the message addressed them as persons inclined to careful thinking. Results can be explained within the framework of self-affirmation theory, which argues that providing people with an opportunity to affirm their sense of selfworth makes them more open to persuasion attempts, as well as more objective. Results are discussed from a wider theoretical and empirical perspective of motivation.

    Hibler, M

    1979-06-01

    According to a number of participants at the population conference in Ontario, sponsored by the School of Journalism of the Univesity of Western Ontario and the Canadian International Development Agency, the villages, in developing countries, have sent a message to population experts, declaring that the most effective way to motivate individuals toward reducing family size is to improve basic educational and health care services. It has been demonstrated that improvements in these areas, by providing women with educational opportunities and by reducing infant mortality, have a direct impact on fertility. Efforts should be directed toward discovering similar direct correlates. The message dismissed as irrelevant the battle raging between those who advocate that population growth must be halted before poverty can be eliminated, between the developmentalists, who believe that fundamental changes in economic and political conditions will automatically solve the population problem, and between those who declare that family planning and development must be dealt with simultaneously for either to be effective. Despite evidence demonstrating the effectiveness of the 'direct correlate' approach, most developing countries continue to accord top priority to family planning programs and neglect educational and health care services.

    Full Text Available Architecture conceived as the superposition of historic contributions and safeguard of the traces and fragments of memory has a unique, irreproducible character in its matter and messages that must be respected by the architect. Now that the concept of restoration as functional, mechanical or typological repairs to the building and the need to correct, amend or formally improve the monument from a contemporary viewpoint has been transcended and a really respectful symbiosis of contemporary methodology has been achieved, the time has come for a sensitive approach, half-way between reason and sentiment, making it possible to minimise the impact of the restoration works on the character and sensitive experience of architecture.

  6. Message Scheduling and Forwarding in Congested DTNs

    KAUST Repository

    Elwhishi, Ahmed

    2012-08-19

    Multi-copy utility-based routing has been considered as one of the most applicable approaches to effective message delivery in Delay Tolerant Networks (DTNs). By allowing multiple message replicas launched, the ratio of message delivery or delay can be significantly reduced compared with other counterparts. Such an advantage, nonetheless, is at the expense of taking more buffer space at each node and higher complexity in message forwarding decisions. This paper investigates an efficient message scheduling and dropping policy via analytical modeling approach, aiming to achieve optimal performance in terms of message delivery delay. Extensive simulation results, based on a synthetic mobility model and real mobility traces, show that the proposed scheduling framework can achieve superb performance against its counterparts in terms of delivery delay.

    In 2010, the U.S. National Weather Service (NWS) funded a three year project to integrate social science into their Tsunami Program. One of three primary requirements of the grant was to make improvements to tsunami warning messages of the NWS' two Tsunami Warning Centers- the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska and the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii. We conducted focus group meetings with a purposive sample of local, state and Federal stakeholders and emergency managers in six states (AK, WA, OR, CA, HI and NC) and two US Territories (US Virgin Islands and American Samoa) to qualitatively asses information needs in tsunami warning messages using WCATWC tsunami messages for the March 2011 Tohoku earthquake and tsunami event. We also reviewed research literature on behavioral response to warnings to develop a tsunami warning message metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order and Formatting and Receiver Characteristics. A message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met. Using findings from this project and findings from a parallel NWS Warning Tiger Team study led by T. Nicolini, the WCATWC implemented the first of two phases of revisions to their warning messages in November 2012. A second phase of additional changes, which will fully implement the redesign of messages based on the metric, is in progress. The resulting messages will reflect current state-of-the-art knowledge on warning message effectiveness. Here we present the message metric; evidence-based rational for message factors; and examples of previous, existing and proposed messages.

    Parent-child communication about sex is an important proximal reproductive health outcome. But while campaigns to promote it such as the Parents Speak Up National Campaign (PSUNC) have been effective, little is known about how messages influence parental cognitions and behavior. This study examines which message features explain responses to sexual communication messages. We content analyzed 4 PSUNC ads to identify specific, measurable message and advertising execution features. We then develop quantitative measures of those features, including message strategies, marketing strategies, and voice and other stylistic features, and merged the resulting data into a dataset drawn from a national media tracking survey of the campaign. Finally, we conducted multivariable logistic regression models to identify relationships between message content and ad reactions/receptivity, and between ad reactions/receptivity and parents' cognitions related to sexual communication included in the campaign's conceptual model. We found that overall parents were highly receptive to the PSUNC ads. We did not find significant associations between message content and ad reactions/receptivity. However, we found that reactions/receptivity to specific PSUNC ads were associated with increased norms, self-efficacy, short- and long-term expectations about parent-child sexual communication, as theorized in the conceptual model. This study extends previous research and methods to analyze message content and reactions/receptivity. The results confirm and extend previous PSUNC campaign evaluation and provide further evidence for the conceptual model. Future research should examine additional message content features and the effects of reactions/receptivity.

    Online social networking sites represent significant new opportunities for Internet advertisers. However, results based on the real world cannot be generalized to all virtual worlds. In this research, the moderating effects of need for cognition (NFC) and knowledge were applied to examine the impact of message framing on attitudes toward social networking sites. A total of 216 undergraduates participated in the study. Results reveal that for social networking sites, while high-NFC individuals form more favorable attitudes toward negatively framed messages than positively framed messages, low-NFC individuals form more favorable attitudes toward positively framed messages than negatively framed messages. In addition, low-knowledge individuals demonstrate more favorable attitudes toward negatively framed messages than positively framed messages; however, the framing effect does not differentially affect the attitudes of high-knowledge individuals. Furthermore, the framing effect does not differentially affect the attitudes of high-NFC individuals with high knowledge. In contrast, low-NFC individuals with low knowledge hold more favorable attitudes toward positively framed messages than negatively framed messages.

    Full Text Available The technology of displaying message is an important part of communication and advertisement. In recent times, Wireless communication has announced its arrival on big stage and the world is going with Smartphone technology. This work describes the design and implementation of a microcontroller based messaging display system. The messaging display system will be interfaced with an android application which will then be used to display information from the comfort of one‘s phone to an LCD screen using the Bluetooth application interface. The work employs the use of an ATMEGA328p Microcontroller mounted on an Arduino board, a Bluetooth Module (HC-06 and an LCD screen. Most of these electronic display systems were using wired cable connections, the Bluetooth technology used in this work is aimed at solving the problem of wired cable connections.The microcontroller provides all the functionality of the display notices and wireless control. A desired text message from a mobile phone is sent via android mobile application to the Bluetooth module located at the receiving end. The Mobile Application was created using online software called App Inventor. When the entire system was connected and tested, it functioned as designed without any noticeable problems. The Bluetooth module responded to commands being sent from the android application appropriately and in a timely manner. The system was able to display 80 characters on the 4 x 20 LCD within the range of 10m as designated by the Bluetooth datasheet.

    Full Text Available Text mining deals with complex and unstructured texts. Usually a particular collection of texts that is specified to one or more domains is necessary. We have developed a customizable text classifier for users to mine the collection automatically. It derives from the sentence category of the HNC theory and corresponding techniques. It can start with a few texts, and it can adjust automatically or be adjusted by user. The user can also control the number of domains chosen and decide the standard with which to choose the texts based on demand and abundance of materials. The performance of the classifier varies with the user's choice.
