    Full Text Available Newborns and infants are often exposed to painful procedures during hospitalization. Several different scales have been validated to assess pain in specific populations of pediatric patients, but no single scale can easily and accurately assess pain in all newborns and infants regardless of gestational age and disease state. A new pain scale was developed, the COVERS scale, which incorporates 6 physiological and behavioral measures for scoring. Newborns admitted to the Neonatal Intensive Care Unit or Well Baby Nursery were evaluated for pain/discomfort during two procedures, a heel prick and a diaper change. Pain was assessed using indicators from three previously established scales (CRIES, the Premature Infant Pain Profile, and the Neonatal Infant Pain Scale, as well as the COVERS Scale, depending upon gestational age. Premature infant testing resulted in similar pain assessments using the COVERS and PIPP scales with an r=0.84. For the full-term infants, the COVERS scale and NIPS scale resulted in similar pain assessments with an r=0.95. The COVERS scale is a valid pain scale that can be used in the clinical setting to assess pain in newborns and infants and is universally applicable to all neonates, regardless of their age or physiological state.

    Previous research has explored whether the Japanese concept of Indecisiveness is different from western cultures. The aim of the study was to develop a questionnaire scale to measure the concept of Japanese Indecisiveness (Yujufudan). In the first study, a factor analysis was carried out using data from 255 college students. Four different factors, “reflection” “procrastination” “referring to others” and “anxiety” were obtained. In the second study, a decision-making task was administered to 55 college students. The scores obtained from the factor analysis in the first study predicted performance on the decision-making task. These results demonstrated the validity and reliability for the Japanese Indecisiveness Scale to measure Japanese Indecisiveness (Yujufudan).

    Full Text Available The development of inexperienced researchers is crucial. In response to the lack of research self-efficacy of many previously disadvantaged individuals, the article examines how mentoring can enhance the research self-efficacy of mentees. The study is grounded in the self-efficacy theory (SET – an aspect of the social cognitive theory (SCT. Insights were gained from an in-depth study of SCT, SET and mentoring, and from a completed mentoring project. This led to the formulation of three basic principles. Firstly, institutions need to provide supportive environmental conditions that facilitate research selfefficacy. This implies a supportive and efficient collective system. The possible effects of performance ratings and reward systems at the institution also need to be considered. Secondly, mentoring needs to create opportunities for young researchers to experience successful learning as a result of appropriate action. To this end, mentees need to be involved in actual research projects in small groups. At the same time the mentor needs to facilitate skills development by coaching and encouragement. Thirdly, mentors need to encourage mentees to believe in their ability to successfully complete research projects. This implies encouraging positive emotional states, stimulating self-reflection and self-comparison with others in the group, giving positive evaluative feedback and being an intentional role model.

    The effect of prior strain injury on myoelectrical activity of the hamstrings during tasks requiring high rates of torque development has received little attention. To determine if recreational athletes with a history of unilateral hamstring strain injury will exhibit lower levels of myoelectrical activity during eccentric contraction, rate of torque development (RTD), and impulse (IMP) at 30, 50, and 100 milliseconds after the onset of myoelectrical activity or torque development in the previously injured limb compared with the uninjured limb. Case control study; Level of evidence, 3. Twenty-six recreational athletes were recruited. Of these, 13 athletes had a history of unilateral hamstring strain injury (all confined to biceps femoris long head), and 13 had no history of hamstring strain injury. Following familiarization, all athletes undertook isokinetic dynamometry testing and surface electromyography (integrated EMG; iEMG) assessment of the biceps femoris long head and medial hamstrings during eccentric contractions at -60 and -180 deg·s(-1). In the injured limb of the injured group, compared with the contralateral uninjured limb, RTD and IMP was lower during -60 deg·s(-1) eccentric contractions at 50 milliseconds (RTD: injured limb, 312.27 ± 191.78 N·m·s(-1) vs uninjured limb, 518.54 ± 172.81 N·m·s(-1), P = .008; IMP: injured limb, 0.73 ± 0.30 N·m·s vs uninjured limb, 0.97 ± 0.23 N·m·s, P = .005) and 100 milliseconds (RTD: injured limb, 280.03 ± 131.42 N·m·s(-1) vs uninjured limb, 460.54 ± 152.94 N·m·s(-1), P = .001; IMP: injured limb, 2.15 ± 0.89 N·m·s vs uninjured limb, 3.07 ± 0.63 N·m·s, P contraction. Biceps femoris long head muscle activation was lower at 100 milliseconds at both contraction speeds (-60 deg·s(-1), normalized iEMG activity [×1000]: injured limb, 26.25 ± 10.11 vs uninjured limb, 33.57 ± 8.29, P = .009; -180 deg·s(-1), normalized iEMG activity [×1000]: injured limb, 31.16 ± 10.01 vs uninjured limb, 39.64

    This study developed evaluation scales for measuring the effects of horticultural therapy in practical settings. Qualitative and quantitative research, including three preliminary studies and a main study, were conducted. In the first study, a total of 779 horticultural therapists answered an open-end questionnaire based on 58 items about elements of occupational therapy and seven factors about singularity of horticultural therapy. In the second study, 20 horticultural therapists participated in in-depth interviews. In the third study, a Delphi method was conducted with 24 horticultural therapists to build a model of assessment indexes and ensure the validity. In the final study, the reserve scales were tested by 121 horticultural therapists in their practical settings for 1045 clients, to verify their reliability and validity. Preliminary questions in the effects area of horticultural therapy were developed in the first study, and validity for the components in the second study. In the third study, an expert Delphi survey was conducted as part of content validity verification of the preliminary tool of horticultural therapy for physical, cognitive, psychological-emotional, and social areas. In the final study, the evaluation tool, which verified the construct, convergence, discriminant, and predictive validity and reliability test, was used to finalise the evaluation tool. The effects of horticultural therapy were classified as four different aspects, namely, physical, cognitive, psycho-emotional, and social, based on previous studies on the effects of horticultural therapy. 98 questions in the four aspects were selected as reserve scales. The reliability of each scale was calculated as 0.982 in physical, 0.980 in cognitive, 0.965 in psycho-emotional, and 0.972 in social aspects based on the Cronbach's test of intra-item internal consistency and half reliability of Spearman-Brown. This study was the first to demonstrate validity and reliability by simultaneously

    To develop and psychometrically test the Post Hip Replacement Comfort Scale (PHRCS). Evaluation of the patient comfort after hip replacement surgery is highly important in order to increase the quality of patient care. The review of the relevant literature shows that a scale that specifically measures the patient comfort after hip replacement surgery is absent. Methodological design was used. This study included the development of the scale and tested the psychometric properties of the scale. 180 patients who had been hip replacement surgery recruited from three education and research hospitals' orthopedic and trauma departments from January 2014 to December 2015. The study was conducted in three phases. In phase 1, scale items were developed based on the literature review and other comfort scales. In phase 2, the trial was applied with data collection forms. Phase 3 was conducted to evaluate the reliability and validity of the finalized inventory using item analysis. The Cronbach's alpha coefficient value is 0.758. Test-retest results found positive and meaningful correlation between the scores of the scales, indicating the reliability of the scale. Scope, surface, criterion and construct validity analysis confirmed the validity of the scale. There were 26 items in the final scale. In our study, the average patient comfort score was 3.64±0.43 (from 1 to 5). The PHRCS is recommended for evaluating patients' comfort after hip replacement surgery and examining the effects of nursing interventions on patients' comfort. Copyright © 2017 Elsevier Inc.

For the development of this scale, 29 items (1.5 times the final number of items were initially selected as preliminary items, based on the previous studies on internet/phone addiction as well as the clinical experience of involved experts. The preliminary scale was administered to a nationally representative sample of 795 students in elementary, middle, and high schools across South Korea. Then, final 15 items were selected according to the reliability test results. The final scale consisted of four subdomains: (1 disturbance of adaptive functions, (2 virtual life orientation, (3 withdrawal, and (4 tolerance. The final scale indicated a high reliability with Cronbach's α of .880. Support for the scale's criterion validity has been demonstrated by its relationship to the internet addiction scale, KS-II (r  =  .49. For the analysis of construct validity, we tested the Structural Equation Model. The results showed the four-factor structure to be valid (NFI  =  .943, TLI  =  .902, CFI  =  .902, RMSEA  =  .034. Smartphone addiction is gaining a greater spotlight as possibly a new form of addiction along with internet addiction. The SAPS appears to be a reliable and valid diagnostic scale for screening adolescents who may be at risk of smartphone addiction. Further implications and limitations are discussed.

    2004-07-01

    Self-assessment assists nurses to maintain and improve their practice by identifying their strengths and areas that may need to be further developed. Professional competence profiles encourage them to take an active part in the learning process of continuing education. Although competence recognition offers a way to motivate practising nurses to produce quality care, few measuring tools are available for this purpose. This paper describes the development and testing of the Nurse Competence Scale, an instrument with which the level of nurse competence can be assessed in different hospital work environments. The categories of the Nurse Competence Scale were derived from Benner's From Novice to Expert competency framework. A seven-step approach, including literature review and six expert groups, was used to identify and validate the indicators of nurse competence. After a pilot test, psychometric testing of the Nurse Competence Scale (content, construct and concurrent validity, and internal consistency) was undertaken with 498 nurses. The 73-item scale consists of seven categories, with responses on a visual analogy scale format. The frequency of using competencies was additionally tested with a four-point scale. Self-assessed overall scores indicated a high level of competence across categories. The Nurse Competence Scale data were normally distributed. The higher the frequency of using competencies, the higher was the self-assessed level of competence. Age and length of work experience had a positive but not very strong correlation with level of competence. According to the item analysis, the categories of the Nurse Competence Scale showed good internal consistency. The results provide strong evidence of the reliability and validity of the Nurse Competence Scale.

    1995-01-01

    Racism may be a factor in low-birth-weight (LBW) and preterm delivery in African American childbearing women. Because no satisfactory measure of racism existed, the Perception of Racism Scale (PRS) was developed. The PRS was pilot tested on 109 participants from churches and community organizations. The scale was then used in a study of 136 childbearing women to investigate LBW and preterm delivery. Twenty items rated on a 4-point Likert-type scale were scored with 1 as the lowest and 4 as the highest perception of racism. Alpha reliabilities were .88 for the pilot and .91 for the study. Content validity was strengthened by expert panel critique. Reliability, content validity, and construct validity were demonstrated and no undue participant burden was observed. The scale is an effective instrument to measure perceptions of racism by African American women.

    Full Text Available In Nigeria, it seems there is sparse of indigenous measure of emotional intelligence. Therefore, this research fills a gap in literature by developing a valid and reliable indigenous scale. To achieve this, the author combined the Bar-On and Goleman’s models of emotional intelligence. In Study 1, 255 items were generated and were reduced to 198 based on expert advice. At the end of several analyses, 52 items were retained. These items were put in a questionnaire form and administered to 850 students in a university. The author determined the factorial validity of the scale using a sample of 834 participants who returned the scale. The scale (using varimax rotation method was then subjected to principal component analysis and 40 items were retained in a 7 well defined factor structure. The factors/dimensions include interpersonal skill (r = .77, empathetic response (r = .73, stress tolerance (r = .69, optimism (r = .75, assertiveness (r = .78, problem solving (r = .74 and flexibility (r = .80. The scale has convergent validity because of its positive relationship with empathy (r = .67 and social intelligence (r = .79 and negative relationships with aggression (r = -.41 and impulsiveness (r = -.32. A test re-test reliability of .79 was also established for the scale.

    While mortality due to pediatric cancer has decreased, suffering has increased due to complex and lengthy treatments. Cancer in adolescence has repercussions on personal and physical development. Although suffering can impede recovery, there is no validated scale in French or English to measure suffering in adolescents with cancer. To develop an objective scale to measure suffering in adolescents with cancer. A methodological design for instrument development was used. Following a MEDLINE search, semistructured interviews were conducted with adolescents 12 to 19 years of age who had undergone four to six weeks of cancer treatment, and with a multidisciplinary cohort of health care professionals. Adolescents with advanced terminal cancer or cognitive impairment were excluded. Enrollment proceeded from the hematology-oncology department⁄clinic in Montreal, Quebec, from December 2011 to March 2012. Content validity was assessed by five health care professionals and four adolescents with cancer. Interviews with 19 adolescents and 16 health care professionals identified six realms of suffering: physical, psychological, spiritual, social, cognitive and global. Through iterative feedback, the Adolescent Cancer Suffering Scale (ACSS) was developed, comprising 41 questions on a four-point Likert scale and one open-ended question. Content validity was 0.98, and inter-rater agreement among professionals was 88% for relevance and 86% for clarity. Adolescents considered the scale to be representative of their suffering. The ACSS is the first questionnaire to measure suffering in adolescents with cancer. In future research, the questionnaire should be validated extensively and interventions developed. Once validated, the ACSS will contribute to promote a holistic approach to health with appropriate intervention or referral.

    2007-03-01

    There is accumulating evidence that prefrontal systems play an important role in management of personal finances, based on studies using clinical populations, functional neuroimaging, and both subjective and objective neuropsychological measures. This study developed the Executive Personal Finance Scale (EPFS) as a specific self-rating measure of executive aspects of personal money management. The resulting 20-item scale had good reliability and showed four factors: impulse control, organization, planning, and motivational drive. Validity was evidenced by correlations with income, credit card debt, and investments. The EPFS also showed logical correlations with compulsive buying and money attitudes. Second-order factor analysis of the EPFS and other scales revealed two higher-order factors of personal finance: cognitive (e.g., planning, organizing) and emotional (e.g., anxiety, impulse-spending, prestige). The EPFS shows good psychometric properties, is easy to use, and will make a convenient complement to other research methodologies exploring the neural basis of personal finance management.

    Betts, Lucy R; Spenser, Karin A

    2017-01-01

    The reported prevalence rates of cyber victimization experiences and cyberbullying behaviors vary. Part of this variation is likely due to the diverse definitions and operationalizations of the constructs adopted in previous research and the lack of psychometrically robust measures. Through 2 studies, the authors developed (Study 1) and evaluated (Study 2) the cyber victimization experiences and cyberbullying behaviors scales. Participants in Study 1 were 393 (122 boys, 171 girls) and in Study 2 were 345 (153 boys, 192 girls) 11-15-year-olds who completed measures of cyber victimization experiences, cyberbullying behaviors, face-to-face victimization experiences, face-to-face bullying behaviors, and social desirability. The 3-factor cyber victimization experiences scale comprised threat, shared images, and personal attack. The 3-factor cyberbullying behaviors scale comprised sharing images, gossip, and personal attack. Both scales demonstrated acceptable internal consistency and convergent validity.

    2011-08-03

    The Savannah River National Laboratory (SRNL) was requested to develop a bench scale test facility, using a mixer, transfer pump, and transfer line to determine the impact of conveying the grout through the transfer lines to the vault on grout properties. Bench scale testing focused on the effect the transfer line has on the rheological property of the grout as it was processed through the transfer line. Rheological and other physical properties of grout samples were obtained prior to and after pumping through a transfer line. The Bench Scale Mixing Rig (BSMR) consisted of two mixing tanks, grout feed tank, transfer pump and transfer hose. The mixing tanks were used to batch the grout which was then transferred into the grout feed tank. The contents of the feed tank were then pumped through the transfer line (hose) using a progressive cavity pump. The grout flow rate and pump discharge pressure were monitored. Four sampling stations were located along the length of the transfer line at the 5, 105 and 205 feet past the transfer pump and at 305 feet, the discharge of the hose. Scaling between the full scale piping at Saltstone to bench scale testing at SRNL was performed by maintaining the same shear rate and total shear at the wall of the transfer line. The results of scaling down resulted in a shorter transfer line, a lower average velocity, the same transfer time and similar pressure drops. The condition of flow in the bench scale transfer line is laminar. The flow in the full scale pipe is in the transition region, but is more laminar than turbulent. The resulting plug in laminar flow in the bench scale results in a region of no-mixing. Hence mixing, or shearing, at the bench scale should be less than that observed in the full scale, where this plug is non existent due to the turbulent flow. The bench scale tests should be considered to be conservative due to the highly laminar condition of flow that exists. Two BSMR runs were performed. In both cases, wall

    The purpose of this study was to develop a meaning of life scale with high validity and reliability. A conceptual framework composed of 4 phases of meanings of life was identified. And 49 preliminary items on a 4-points scale were developed through content validity. A reliability and validity test of the 49 items was conducted on 564 adults. By means of internal consistency of the 49 items, 1 item was deleted. To verify the 48 items, factor analysis, reliability test, and LISEREL were done. Through exploratory factor analysis of the 48 items, 8 factors were extracted. These factors were labeled as 'self- awareness and self-acceptance', 'hope', 'responsibility awareness', 'love experience', 'self transcendence', 'relation experience', 'self contentedness', and 'Commitment'. Through LISEREL of the 48 items, 2 items were excluded and finally 46 items remained. Cronbach's Alpha of the 46 items was .94. The correlation coefficient of the Self-esteem scale was .79. By the above results, the researchers recommend the following: An exploratory study on the variables related to the meaning of life are needed for criterion validity of this scale. Studies on meaning of life of different group, and subjects are needed for reverification.

  9. Development and standardization of Mysore Tridosha scale.

    Shilpa, S; Murthy, C G Venkatesha

    2011-07-01

    The authors have developed a personality scale to assess Tridoshas i.e. Vata, Pitta, and Kapha from psychological perspective in human beings. The Tridoshas are composed of the Pancha Mahabhutas, but one or the other Dosha is dominant singularly or in combination. There can never be a state when one or the other Pancha Mahabhutas and consequently the Tridoshas are absent totally. All five are essential to sustain life. Vata Dosha is composed of Akasa and Vayu Mahabhuta. Pitta Dosha is composed of Tejas or Agni and Ap Mahabhuta. Kapha Dosha is composed of Ap and Prithvi Mahabhuta. Although Tridosha is studied, understood, and applied in Ayurveda, the present authors have tried to validate the same from the domain of psychology. Since the authors are not from the domain of Ayurveda but of Psychology, there are some constructs that are not amenable for psychological testing which have been ignored. Only those constructs that can be used by psychologists to assess the psychological aspects of the Dosha Prakriti have been used to build items for the assessment of personality. In this process, the psychometric properties of the scale are established. The scale assesses the psychological manifestation of the Tridoshas, which was the basic objective. The standardization procedure involved in the development of the Mysore Psychological Tridosha Scale is herewith delineated.

    1997-01-01

    A study was conducted in which the cumulative environmental effects of mega-hydroelectric development projects such as the James Bay development in Canada, the Sardar Sarovar development in India and the Three Gorges development in China were examined. The extent of flooding as a result of these projects and of many others around the world was presented. The study showed that several factors are responsible for methyl mercury (MeHg) bioaccumulation in reservoirs. The study also revealed that reservoirs can be a significant source of greenhouse gas emissions. Boreal forests in particular, when flooded, become a strong source of greenhouse gases to the atmosphere. This results from the fact that after flooding a boreal forest changes from being a small carbon sink to a large source of carbon to the atmosphere, due to stimulated microbial production of CO 2 and CH 4 by decomposition of plant tissues and peat. This increased decomposition also results in an increase of another microbial activity, namely the methylation of inorganic mercury to the much more toxic MeHg. Selected examples of the downstream effects of altered flows caused by large-scale hydroelectric developments world-wide were summarized. A similar tabulation provided examples of social impacts of relocation of people necessitated by large-scale hydroelectric development. 209 refs., 10 tabs., 3 figs

    Anger is a pervasive problem after individuals experience traumatic stress that heightens the risk for violence, health problems, poor relationships, and poor treatment outcomes. Previous research has demonstrated a moderate relationship between anger and posttraumatic stress disorder (PTSD), yet this research also highlights that anger has not been rigorously measured in the context of PTSD. Thus, this study concerns the development of a complimentary measure to assess anger in the context o...

    Full Text Available In musical instrument training, piano has been taught as a compulsory instrument in all departments of Music Education. It is thought that as a major instrument,  piano  plays a crucial role in music education. Without question, it is highly vital to raise individuals' awareness  of learning styles towards learning piano in effort to practice piano courses more efficiently and effectively. In this respect, the present study is of utmost importance as it will be a pioneer study and make a great deal of contributions to the relavant field. The current study was designed to develop a valid and reliable scale. The population of the study consisted of 170 music teacher candidates majoring in Music Education, including those who already took piano lessons. Although the study successfully accessed to the whole sample, only 133 scales were included to the research, however, due to inaccurate or incomplete data in subjects’ responses. To test the construct validity of the scale,  explanatory factor analysis (EFA and confirmatory factor analysis (CFA were used. The scale consists of  four sub-dimensions, namely, independent, analytical, dependent and affective learning styles.

  13. The development of an annoyance scale for community noise assessment

    Levine, N.

    1981-01-01

    The development of an annoyance scale for use in community noise assessment is described. In previous studies in which annoyance scales have been used descriptors, intervals, and metrics have been variable and non-standard. Such variability may be a serious shortcoming in comparing studies of assessment of noise reactions. It is not clear how many semantic distinctions can be made to describe subjective reactions to noise, especially the degree of annoyance. There is also great variability in language use reflecting educational, social class, regional and sub-cultural differences. Finally, scaling annoyance responses ordinally, when the underlying intervals are skewed, may seriously distort relationships when analyzed with parametric statistics. In the research described here, an attempt has been made to produce a standardized annoyance scale with descriptors marking clear semantic distinctions, roughly equidistant from each other, and having wide acceptability. Using the Thurstone scaling method, 51 subjects from both high and low educational backgrounds were asked to rate 43 different descriptors of annoyance. The results show that six to seven semantic distinctions can be made. Seven descriptors which mark off roughly equal-sized intervals and which show the greatest agreement are chosen for an annoyance scale. It is felt that the use of such a scale may be more useful in comparing subjective response to noise. Data from a survey lend support to this.

    Research into excessive work has gained increasing attention over the last 20 years. Terms such as "workaholism,"work addiction" and "excessive work" have been used interchangeably. Given the increase in empirical research, this study presents the development of the Bergen Work Addiction Scale (BWAS), a new psychometrically validated scale for the assessment of work addiction. A pool of 14 items, with two reflecting each of seven core elements of addiction (i.e., salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) was initially constructed. The items were then administered to two samples, one recruited by a web survey following a television broadcast about workaholism (n = 11,769) and one comprising participants in the second wave of a longitudinal internet-based survey about working life (n = 368). The items with the highest corrected item-total correlation from within each of the seven addiction elements were retained in the final scale. The assumed one-factor solution of the refined seven-item scale was acceptable (root mean square error of approximation = 0.077, Comparative Fit Index = 0.96, Tucker-Lewis Index = 0.95) and the internal reliability of the two samples were 0.84 and 0.80, respectively. The scores of the BWAS converged with scores on other workaholism scales, except for a Work Enjoyment subscale. A suggested cut-off for categorization of workaholics showed good discriminative ability in terms of working hours, leadership position, and subjective health complaints. It is concluded that the BWAS has good psychometric properties. © 2012 The Authors. Scandinavian Journal of Psychology © 2012 The Scandinavian Psychological Associations.

    Full Text Available Codependency is defined as a dysfunctional pattern of relating to others, present in relatives of those with a substance use disorder or other chronic disease. It is characterized by emotional dependence, extreme focus in the other person, and self-neglect. Aim: to present results of the process of development and validation of a new measure to evaluate codependency. Method: The Argentinean codependency scale was administered to a convenience sample of 347 subjects between 15 and 80 years, in Mar del Plata. AFE was used (main axes extraction method. The number of factors was determined by parallel analysis. Internal consistency was assessed using Cronbach's Alpha. Item level statistics were also estimated. Results: Three factors were obtained. The internal consistency of the total scale and the three subscales was satisfactory. Relatives of alcohol or drugs dependents and of people with other chronic diseases had scores significantly higher in the codependency measure than those in the general population group.

    2017-10-01

    The purpose of the project was to review content validity and assess the span of responses for the newly developed Clinical Functional Impairment Scale (CFIS). A cross-sectional, content validity process using focus groups of developmental, behavioral pediatric clinicians was conducted. After qualitative analysis of the focus group data, adjustments were made in the CFIS based on the recommendations of the content experts. A survey was conducted of clinicians participating in the online Society of Developmental and Behavioral Pediatrics Discussion Board. Clinicians reviewed 2 case studies and used the CFIS to score severity and interval change of predetermined functional impairments. The amount of spread in the answers was assessed by calculating the index of dispersion. Qualitative analysis of the focus groups resulted in adjustment to the CFIS to 20 functional impairments, with a 5-point Likert scale of severity and a 7-point Likert scale of interval change. Ninety-four clinicians participated in the survey. The index of dispersion ranged from 0.49 to 0.88. The interval ratings of severity and interval change had lower dispersion ranges. The CFIS uses a mutual prioritization by the family and clinician of the child's functional impairments. The study demonstrated that the clinicians' ratings of the case studies were more variable in the initial symptom severity score than their ratings of symptom severity and interval change in symptoms. Further testing of the CFIS is planned using face-to-face clinical encounters and including parent/caregiver ratings of severity and interval change.

    2013-01-01

    [Purpose] The world of competitive sports has its own unique subculture which at times works towards covering up psychological problems faced by athletes with injuries. The purpose of this study was to develop an “Athletic Injury Psychological Acceptance Scale (AIPAS)” to screen athletes for serious psychological problems resulting from injury. [Subjects] A total of 189 subjects responded to the survey, of which 168 (mean age= 19.93 years; average number of days unable to participate in sports= 71.84 days, SD = 88.01 days) valid responses were subjected to analysis. [Methods] A provisional version of the AIPAS was created from question items based on face-to-face subject interviews and content validity testing by specialists. In order to test criterion-related validity of the AIPAS, subjects were asked to complete indices that would serve as an external criterion. For this purpose, indices that measure athletic rehabilitation dedication and time perspective were designed. [Results] Item analysis of the provisional AIPAS was conducted to confirm the discrimination of each item. Exploratory factor analysis identified “Self-motivation” and “Focus on the Present” as two factors of the provisional scale. Confirmatory factor analysis supported these results. The Cronbach’s alpha was used to measure the internal consistency. Since α=0.81, the reliability of the scale was confirmed. A significant correlation was found between AIPAS and external indices, indicating criterion-related validity. [Conclusion] AIPAS is a reliable and valid scale composed of two subscales.

    We report the development and validation of a scale to measure online shopping addiction. Inspired by previous theories and research on behavioral addiction, the Griffiths's widely accepted six-factor component model was referred to and an 18-item scale was constructed, with each component measured by three items. The results of exploratory factor analysis, based on Sample 1 (999 college students) and confirmatory factor analysis, based on Sample 2 (854 college students) showed the Griffiths's substantive six-factor structure underlay the online shopping addiction scale. Cronbach's alpha suggested that the resulting scale was highly reliable. Concurrent validity, based on Sample 3 (328 college students), was also satisfactory as indicated by correlations between the scale and measures of similar constructs. Finally, self-perceived online shopping addiction can be predicted to a relatively high degree. The present 18-item scale is a solid theory-based instrument to empirically measure online shopping addiction and can be used for understanding the phenomena among young adults. PMID:28559864

    2013-10-01

    The purpose of this study was to develop a scale for assessing the attributes of the heterosexual love of alcoholics. Using the characteristics and categories related to the heterosexual love of alcoholics found in previous research, we created a "Heterosexual Love Assessment Scale for Alcoholics" and conducted a survey among 110 alcoholics (80 men and 30 women). The following three factors were extracted from the results: "mutual respect", "superficial intimacy", and "fear of being disliked", A high level of reliability was obtained on the scales indicated below (alpha = 63-82), and concurrent validity was confirmed between these and the Adult Attachment Scale (ECR: Experiences in Close Relationships inventory). Further, correlations were found between "mutual respect" and the benefit of heterosexual love in recovery, and between the other two factors and the impediment of heterosexual love, and between the Denial & Awareness Scale (for alcoholic). As this scale can be used to assess the type of heterosexual love of alcoholics, we predict that it will be useful in examining the effects of heterosexual love on recovery and as a tool for offering advice.

    The Bergen Facebook Addiction Scale (BFAS), initially a pool of 18 items, three reflecting each of the six core elements of addiction (salience, mood modification, tolerance, withdrawal, conflict, and relapse), was constructed and administered to 423 students together with several other standardized self-report scales (Addictive Tendencies Scale, Online Sociability Scale, Facebook Attitude Scale, NEO-FFI, BIS/BAS scales, and Sleep questions). That item within each of the six addiction elements with the highest corrected item-total correlation was retained in the final scale. The factor structure of the scale was good (RMSEA = .046, CFI = .99) and coefficient alpha was .83. The 3-week test-retest reliability coefficient was .82. The scores converged with scores for other scales of Facebook activity. Also, they were positively related to Neuroticism and Extraversion, and negatively related to Conscientiousness. High scores on the new scale were associated with delayed bedtimes and rising times.

    Most measures of spirituality privilege religious spirituality, but people may experience spirituality in a variety of ways, including a sense of closeness, oneness, or connection with a theistic being, the transcendent (i.e., something outside space and time), oneself, humanity, or nature. The overall purpose of the present 4 studies was to develop the Sources of Spirituality (SOS) Scale to measure these different elements of spirituality. In Study 1, we created items, had them reviewed by experts, and used data from a sample of undergraduates (N = 218) to evaluate factor structure and inform initial measurement revisions. The factor structure replicated well in another sample of undergraduates (N = 200; Study 2), and in a sample of community adults (N = 140; Study 3). In a sample of undergraduates (N = 200; Study 4), we then evaluated evidence of construct validity by examining associations between SOS Scale scores and religious commitment, positive attitudes toward the Sacred, and dispositional connection with nature. Moreover, based on latent profile analyses results, we found 5 distinct patterns of spirituality based on SOS subscales. We consider implications for therapy and relevance of the findings for models of spirituality and future research. (c) 2015 APA, all rights reserved).

    Technological advancements, particularly in the field of geographic information systems (GIS), have made it possible to predict the likelihood of foodborne pathogen contamination in produce production environments using geospatial models. Yet, few studies have examined the validity and robustness of such models. This study was performed to test and refine the rules associated with a previously developed geospatial model that predicts the prevalence of Listeria monocytogenes in produce farms in New York State (NYS). Produce fields for each of four enrolled produce farms were categorized into areas of high or low predicted L. monocytogenes prevalence using rules based on a field's available water storage (AWS) and its proximity to water, impervious cover, and pastures. Drag swabs (n = 1,056) were collected from plots assigned to each risk category. Logistic regression, which tested the ability of each rule to accurately predict the prevalence of L. monocytogenes, validated the rules based on water and pasture. Samples collected near water (odds ratio [OR], 3.0) and pasture (OR, 2.9) showed a significantly increased likelihood of L. monocytogenes isolation compared to that for samples collected far from water and pasture. Generalized linear mixed models identified additional land cover factors associated with an increased likelihood of L. monocytogenes isolation, such as proximity to wetlands. These findings validated a subset of previously developed rules that predict L. monocytogenes prevalence in produce production environments. This suggests that GIS and geospatial models can be used to accurately predict L. monocytogenes prevalence on farms and can be used prospectively to minimize the risk of preharvest contamination of produce.

    Gestational diabetes is considered a variant of diabetes mellitus as they share a common pathophysiological basis: insulin resistance in target and insufficient secretion of it by pancreatic p-cell bodies. Pregnancy is a unique physiological situation provides an opportunity to identify future risk of diabetes mellitus. To determine the long-term incidence of diabetes mellitus in women who have previously been diagnosed with gestational diabetes and identifying clinical risk factors for developing the same. nested case-control cohort study. 671 patients between 1996 and 2009 were diagnosed with gestational diabetes were selected. The incidence of diabetes mellitus was estimated and 2 subgroups were formed: Group A or cases: women who develop diabetes mellitus after diagnosis of gestational diabetes. Group B or control: random sample of 71 women with a history of gestational diabetes in the follow-up period remained normoglycemic. Both groups were studied up to 18 years postpartum. By studying Kaplan Meier survival of the influence of different gestational variables it was obtained in the later development of diabetes mellitus with time parameter and COX models for categorical variables were applied. Significant variables were studied by multivariate Cox analysis. In all analyzes the Hazard ratio was calculated with confidence intervals at 95%. The incidence of diabetes mellitus was 10.3% in patients with a history of gestational diabetes. They were identified as risk factors in the index pregnancy to later development of diabetes mellitus: greater than 35 and younger than 27 years maternal age, BMI greater than 30 kg/m2, hypertensive disorders of pregnancy, insulin therapy, poor metabolic control and more than a complicated pregnancy with gestational diabetes. Clinical factors have been identified in the pregnancy complicated by gestational diabetes that determine a higher probability of progression to diabetes mellitus in the medium and long term.

    This paper explores the transformations of the housebuilding industry under the policy requirement to build on previously developed land (PDL). This requirement was a key lever in promoting the sustainable urban development agenda of UK governments from the early 1990s to 2010 and has survived albeit somewhat relaxed and permutated in the latest National Planning Policy Framework (NPPF). The paper therefore looks at the way in which the policy push towards densification and mixed use affected housebuilders' business strategy and practices and their ability to cope with the 2007 downturn of the housing market and its aftermath. It also points out the eventual feedback of some of these practices into planning policy. Following the gradual shift of British urban policy focus towards sustainability which started in the early 1990s, new configurations of actors, new skills, strategies and approaches to managing risk emerged in property development and housebuilding. There were at least two ways in which housebuilders could have responded to the requirements of developing long term mixed use high density projects on PDL. One way was to develop new products and to employ practices and combinations of practices involving phasing, a flexible approach to planning applications and innovative production methods. Alternatively, they could approach PDL development as a temporary turn of policy or view mixed use high density schemes as a niche market to be explored without drastically overhauling the business model of the entire firm. These transformations of the UK housebuilding sector were unfolding during a long period of buoyancy in the housing market which came to an end in 2007. Very little is known both about how housebuilder strategies and production practices evolved during the boom years as well as about how these firms coped with the effects of the 2007 market downturn.

    In recent years, issues surrounding transgender have garnered media and legal attention, contributing to rapidly shifting views on gender in the U.S. Yet, there is a paucity of data-driven studies on the public's views of transgender identity. This study reports the development and validation of the Transgender Attitudes and Beliefs Scale (TABS). After constructing an initial 96-item pool from consulting experts and existing scales, Phase 1 of the study was launched, involving an exploratory factor analysis of 48 items. The initial factor analysis with 295 participants revealed three factors across 33 items-16 items on interpersonal comfort, 11 on sex/gender beliefs, and 6 on human value. The internal consistency of each factor was high-α = .97 for Factor 1, α = .95 for Factor 2, and α = .94 for Factor 3. A confirmatory factor analysis was conducted in the second phase with an independent sample consisting of 238 participants. The Attitudes Toward Transgender Individual Scale and the Genderism and Transphobia Scale were also included to test for convergent validity, and the Rosenberg Self-Esteem Scale and the short form of the Marlowe-Crowne Social Desirability Scale were utilized to test discriminant validity. Both of the data collection phases employed MTurk, a form of online sampling with increased diversity compared to college student samples and more generalizability to the general U.S. TABS represents an addition to the literature in its ability to capture a more nuanced conceptualization of transgender attitude not found in previous scales.

    Four dimensions of inner strength were previously identified in a meta-theoretical analysis: firmness, creativity, connectedness, and flexibility. The aim of this study was to develop an Inner Strength Scale (ISS) based on those four dimensions and to evaluate its psychometric properties. An initial version of ISS was distributed for validation purpose with the Rosenberg Self-Esteem Scale, the resilience scale, and the sense of Coherence Scale. A convenience sample of 391 adults, aged 19-90 years participated. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were used in the process of exploring, evaluating, and reducing the 63-item ISS to the 20-item ISS. Cronbach's alpha and test-retest were used to measure reliability. CFA showed satisfactory goodness-of-fit for the 20-item ISS. The analysis supported a fourfactor solution explaining 51% of the variance. Cronbach's alpha on the 20-item ISS was 0.86, and the test-retest showed stability over time (r=0.79). The ISS was found to be a valid and reliable instrument for capturing a multifaceted understanding of inner strength. Further tests of psychometric properties of the ISS will be performed in forthcoming studies. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Stress in pregnancy can lead to low-birth-weight and preterm babies and to psychological consequences such as anxiety and depression during pregnancy and the puerperium. Previous scales to measure stress contain items that overlap with the symptoms of pregnancy. A stress scale was developed based on in-depth interviews with pregnant women in Pakistan. Construct validity, test-retest reliability and inter-rater reliability were carried out. Cronbach alpha was 0.82 for the 30 short-listed items, with item-total correlations of 0.2-0.8. Multidimensional scaling determined 2 dimensions: socioenvironmental hassles and chronic illnesses. This was the first scale developed for pregnant women based on stressors in a developing country in South Asia.

    The development of an adult organism from a fertilized egg remains one of the deep mysteries of biology. Great strides have been made in the past three decades, primarily through ever more sophisticated genetic analyses and the advent of live-cell imaging, yet the underlying principles governing development are elusive. Recently, a new generation of biological physicists has entered the field, attracted by the hallmarks of development— coordinated dynamics and pattern formation arising from cell-cell interactions—which reflect tantalizing analogs with many-body systems in condensed matter physics and related fields. There have been corresponding influxes of researchers from other quantitative disciplines. With new workers come new questions and foci at different scales in space, time and complexity. The reductionist philosophy of developmental genetics has become increasingly complemented by a search for effective mechanisms at higher scales, a strategy which has a proven track record of success in the study of complex systems in physics. Are there new and universal mechanisms of development, supra-genetic in nature, waiting to be discovered by focusing on higher scales, or is development fundamentally the intricately scripted unfolding of complex genetic instructions? In this special focus issue of Physical Biology, we present cutting-edge research into embryo development from a broad spectrum of groups representing cell and developmental biology, biological physics, bioengineering and biomathematics. We are provided with a sense of how this multidisciplinary community views the fundamental issue of scale in development and are given some excellent examples of how we can bridge these scales through interdisciplinary collaboration, in order to create new levels of understanding. We start with two reviews which will provide newcomers with a guide to some of the outstanding questions in the field. Winklbauer and Müller use the phenomenon of mesoderm spreading as

  3. Toward a Common Ontology of Scaling Up in Development

    April N. Frake

    2018-03-01

    Full Text Available Scaling up development measures to target global food insecurity has a distinctly spatial character and is often cited as a solution to the global hunger crisis. Development does not occur without scaling and consensus on the ontological meaning of scaling up is a vital component to developing sustainable solutions to the global hunger crisis across geographical scales. Yet ‘scaling up’, while frequently used throughout Research and Development (R&D and Natural Resource Management (NRM literature, lacks ontological agreement. We begin by considering the noun, ‘scale’ and existing literature on scaling up, then present a visual analysis of definitions provided for scaling up across development institutions. Our study finds that the organization of terms used across these definitions falls into three distinct categories: Interventions, Mechanisms, and Outcomes. Further, we contend that the continued uncertainty is linked to scale being applied in two fashions: as a noun (outcome and verb (process. Rather than calling for reformed definitions, we argue for precision of definitions. To that end, we present a conceptual framework of scaling up that gives greater emphasis on separating the noun scale, from the verb, to scale. Further, Monitoring and Evaluation (M&E in our model complements scaling efforts beginning with how scaling up is defined by program, through to final evaluation of success.

    This research examined the possibility of developing Mokken cumulative scales measuring attitudes toward illegal immigrants in a 9-nation sample. A total of 1,407 respondents primarily from national and regional universities participated in the surveys including the 20-item Illegal Immigration Scale. The scales displayed acceptable reliability with coefficients alpha ranging from .79 to .93. A Procrustes analysis yielded coefficients of congruence with the previously established three-factor solution. The amount of variance accounted for varied between 33.1 and 54.7%, supporting the presence of other factors in attitudes toward illegal immigrants. Mokken scale analysis yielded robust and economical scales in two clusters of national samples.

    The determination of uranium with arsenazo is hindered by a great number of cation which form stable complexes with the reactive and may given rise to serious interferences. By studying the optimum conditions of uranium the extraction be means of tributylphosphate solutions dissolved in methylisobuthylketone, under conditions for previous masking of the interfering cations, an organic extract was obtained containing all the uranium together with small amounts of iron. The possible interference derived from the latter element is avoided by reduction with hydroxylammoniumchlorid followed by complex formation of the Fe(II)-ortophenantroline compound in alcoholic medium.

    2017-04-01

    Current surface wave magnitude equations normally take into account only the vertical component of peak ground displacement, and therefore only contributions from Rayleigh waves. Horizontal components contain both Rayleigh and Love waves, which potentially obscure attenuation characteristics. With the advent of rotational ground motion observations from instruments such as ring laser gyroscopes and fibre-optic gyroscopes, it is now possible to determine peak amplitudes of rotations about the vertical axis. At teleseismic distances, these are dominated by Love waves and are in principle unaffected by Rayleigh waves. We aim to use this concept to determine a Love wave based surface wave magnitude equation; with a large database of rotational ground motion events of varying source parameters, we intend to empirically define a rotational magnitude scale and consequently an amplitude decay law for Love waves.

    2009-12-01

    With the advent of the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) system, domestic (U.S.) and international earthquake responders are reconsidering their automatic alert and activation levels as well as their response procedures. To help facilitate rapid and proportionate earthquake response, we propose and describe an Earthquake Impact Scale (EIS) founded on two alerting criteria. One, based on the estimated cost of damage, is most suitable for domestic events; the other, based on estimated ranges of fatalities, is more appropriate for most global events. Simple thresholds, derived from the systematic analysis of past earthquake impact and response levels, turn out to be quite effective in communicating predicted impact and response level of an event, characterized by alerts of green (little or no impact), yellow (regional impact and response), orange (national-scale impact and response), and red (major disaster, necessitating international response). Corresponding fatality thresholds for yellow, orange, and red alert levels are 1, 100, and 1000, respectively. For damage impact, yellow, orange, and red thresholds are triggered by estimated losses exceeding 1M, 10M, and $1B, respectively. The rationale for a dual approach to earthquake alerting stems from the recognition that relatively high fatalities, injuries, and homelessness dominate in countries where vernacular building practices typically lend themselves to high collapse and casualty rates, and it is these impacts that set prioritization for international response. In contrast, it is often financial and overall societal impacts that trigger the level of response in regions or countries where prevalent earthquake resistant construction practices greatly reduce building collapse and associated fatalities. Any newly devised alert protocols, whether financial or casualty based, must be intuitive and consistent with established lexicons and procedures. In this analysis, we make an attempt

    The inflatable antenna for CubeSat is a 1 meter antenna reflector designed with one side reflective Mylar, another side clear Mylar with a patch antenna at the focus. The development of this technology responds to the increasing need for more capable communication systems to allow CubeSats to operate autonomously in interplanetary missions. An initial version of the antenna for the S-Band was developed and tested in both anechoic chamber and vacuum chamber. Recent developments in transceivers and amplifiers for CubeSat at X-band motivated the extension from the S-Band to the X-Band. This paper describes the process of extending the design of the antenna to the X-Band focusing on patch antenna redesign, new manufacturing challenges and initial results of experimental tests.

    2011-02-01

    An ink pad and paper, pressure-sensitive platforms, and photography have previously been used to collect footprint data used in clinical assessment. Digital scanners have been widely used more recently to collect such data. The purpose of this study was to evaluate the intra- and interrater reliability of a flatbed digital image scanning technology to capture footprint data. This study used a repeated-measures design on 32 (16 male 16 female) healthy subjects. The following measured indices of footprint were recorded from 2-dimensional images of the plantar surface of the foot recorded with an Associate Platinum (Foot Levelers Inc, Roanoke, VA) digital foot scanner: Staheli index, Chippaux-Smirak index, arch angle, and arch index. Intraclass correlation coefficient (ICC) values were calculated to evaluate intrarater, interday, and interclinician reliability. The ICC values for intrarater reliability were greater than or equal to .817, indicating an excellent level of reproducibility in assessing the collected images. Analyses of variance revealed that there were no significant differences between raters for each index (P > .05). The ICC values also indicated excellent reliability (.881-.971) between days and clinicians in all but one of the indices of footprint, arch angle (.689), with good reliability between clinicians. The full-factorial analysis of variance model did not reveal any interaction effects (P > .05), which indicated that indices of footprint were not changing across days and clinicians. Scanning technology used in this study demonstrated good intra- and interrater reliability measurements of footprint indices, as demonstrated by high ICC values.

  4. Hemoglobin-Based Oxygen Carrier (HBOC) Development in Trauma: Previous Regulatory Challenges, Lessons Learned, and a Path Forward.

    Science.gov (United States)

    Keipert, Peter E

    2017-01-01

    Historically, hemoglobin-based oxygen carriers (HBOCs) were being developed as "blood substitutes," despite their transient circulatory half-life (~ 24 h) vs. transfused red blood cells (RBCs). More recently, HBOC commercial development focused on "oxygen therapeutic" indications to provide a temporary oxygenation bridge until medical or surgical interventions (including RBC transfusion, if required) can be initiated. This included the early trauma trials with HemAssist ® (BAXTER), Hemopure ® (BIOPURE) and PolyHeme ® (NORTHFIELD) for resuscitating hypotensive shock. These trials all failed due to safety concerns (e.g., cardiac events, mortality) and certain protocol design limitations. In 2008 the Food and Drug Administration (FDA) put all HBOC trials in the US on clinical hold due to the unfavorable benefit:risk profile demonstrated by various HBOCs in different clinical studies in a meta-analysis published by Natanson et al. (2008). During standard resuscitation in trauma, organ dysfunction and failure can occur due to ischemia in critical tissues, which can be detected by the degree of lactic acidosis. SANGART'S Phase 2 trauma program with MP4OX therefore added lactate >5 mmol/L as an inclusion criterion to enroll patients who had lost sufficient blood to cause a tissue oxygen debt. This was key to the successful conduct of their Phase 2 program (ex-US, from 2009 to 2012) to evaluate MP4OX as an adjunct to standard fluid resuscitation and transfusion of RBCs. In 2013, SANGART shared their Phase 2b results with the FDA, and succeeded in getting the FDA to agree that a planned Phase 2c higher dose comparison study of MP4OX in trauma could include clinical sites in the US. Unfortunately, SANGART failed to secure new funding and was forced to terminate development and operations in Dec 2013, even though a regulatory path forward with FDA approval to proceed in trauma had been achieved.

METHOD: Participants were a total of 341 primary school children, 4th and f4th grade for 152 students, 6th, 7th and 8th grade for 162 students aged between 10-14.Skinner (1996, perceived control based on the theory is created 12-item scale of perceived control of the general form of the trial for primary education children and this form, within the scope of the research subjects, are given in order to make the validity and reliability studies. In order to test the validity of the scale developed, Satisfaction with Life was used. This scale was developed by Diener et al. (1985 and adapted into Turkish by Yetim (1993. RESULTS:Exploratory and confirmatory factor analysises and certain reliability analyses were used in the study. As a result of the analysis, four Likert-type five items scale were obtained. The findings revealed one -dimensional scale, 46.35% of whose variance was explained. Cronbach’s coefficient alpha provided evidence for the internal consistency of the exploratory the Scale. The reliability of the scale was 0.70 and indicated that the 5 item scale had good internal consistency for the sample. CONCLUSION: The scale that resulted was given the title “Scale for Primary School Children’ Time Orientation during Classroom Disengagement”. This instrument may be used in various studies in the future, thus contributing to the development of the field. [TAF Prev Med Bull 2012; 11(3.000: 331-338

  6. Evolutionary relationships of the Critically Endangered frog Ericabatrachus baleensis Largen, 1991 with notes on incorporating previously unsampled taxa into large-scale phylogenetic analyses

    Science.gov (United States)

    2014-01-01

    Background The phylogenetic relationships of many taxa remain poorly known because of a lack of appropriate data and/or analyses. Despite substantial recent advances, amphibian phylogeny remains poorly resolved in many instances. The phylogenetic relationships of the Ethiopian endemic monotypic genus Ericabatrachus has been addressed thus far only with phenotypic data and remains contentious. Results We obtained fresh samples of the now rare and Critically Endangered Ericabatrachus baleensis and generated DNA sequences for two mitochondrial and four nuclear genes. Analyses of these new data using de novo and constrained-tree phylogenetic reconstructions strongly support a close relationship between Ericabatrachus and Petropedetes, and allow us to reject previously proposed alternative hypotheses of a close relationship with cacosternines or Phrynobatrachus. Conclusions We discuss the implications of our results for the taxonomy, biogeography and conservation of E. baleensis, and suggest a two-tiered approach to the inclusion and analyses of new data in order to assess the phylogenetic relationships of previously unsampled taxa. Such approaches will be important in the future given the increasing availability of relevant mega-alignments and potential framework phylogenies. PMID:24612655

    2004-08-01

    In this study, an Interpersonal Cognitive Distortions Scale was developed to assess cognitive distortions in individuals' interpersonal relationships. The sample comprised 425 university students. A factor analysis yielded three factors: Interpersonal Rejection, Unrealistic Relationship Expectation and Interpersonal Misperception. To examine construct validity the correlations between the scores on the Interpersonal Cognitive Distortions Scale and the Automatic Thoughts Scale (.54), the Irrational Belief Scale (.54), and the Conflict Tendency Scale (.53) were estimated. The first factor, the second factor, and the total scale discriminated married individuals who had low and high conflict intensity and conflict frequency. The reliability of the scale was estimated by performing a test-retest correlation (.74). Cronbach internal consistency coefficient alpha was .67.

    Attitudes toward homosexuality vary across cultures, with the legal and societal position being rather complicated in India. This study describes the process of developing and validating a Likert-type scale to assess attitudes toward homosexuality among heterosexuals. Phase 1 describes the development of the scale. Items were written based on thematic analysis of narratives generated from 50 college students and reviewing existing scales. After administering the 70-item scale to 68 participants, item analysis yielded 20 statements with item-total correlations over .70. Cronbach's alpha was .97. In Phase 2, the 20-item Attitudes Toward Homosexuality Scale for Indians (AHSI) was administered to 142 participants. Analysis yielded a corrected split-half correlation of .91. Further, AHSI discriminated between women and men; between liberal arts and STEM/business students; and those who reported interpersonal contact with gay men and lesbian women and those who did not. The scale has satisfactory reliability and shows promising construct validity.

    Based on the assumption that leadership can be developed and college students possess leadership potential before becoming adult leaders, a Leadership Potential Scale was developed for Korean college students. Factors of leadership were extracted and preliminary items were developed through a literature review and semi-structured interviews. The items were assessed by experts for face validity, and the 12 factors and 78 items of the Leadership Potential Scale were derived from a factor analysis of data from 305 college students. The results of a subsequent study (N = 320) indicate the scale is ready to be further validated in a known-groups design.

    Full Text Available The purposes of this study were 1 to develop a social behavior assessment system for adolescent - social competence scale; and 2 to evaluate the reliability and validity of this proposed scale. The social behavior assessment system for adolescent comprised three scales: the teacher rating scale (TRS, parent rating scale (PRS, and self-report scale (SRS. TRS, PRS, and SRS all included 110 items in two scales: social competence scale (SCS and problem behavior scale (PBS. The social competence scale consisted of 48 items divided into seven subscales for measuring three theoretical dimensions: self-control, interpersonal interaction, and academic behavior. The development of social competence scale yielded the following results regarding validity: 1 evidence based on test content was established and supported by exploring literature and expert validity; 2 TRS-SCS, PRS-SCS, and SRS-SCS all have high internal consistency reliability and 4-week-interval re-test reliability. Besides, the inter-rater reliability between teachers, parents and students were lower to moderate; 3 the concurrent criterion related evidence of the TRS-SCS and PRS-SCS to the behavioral and emotional rating scale and the SRS-SCS to the Beck youth inventories were all significant; 4 the discriminant evidence of TRS-SCS was found to be considerably satisfactory in discriminating children with emotional and behavioral problems from those without; 5 evidence based on internal structure indicates that the results of confirmatory factory analysis were found considerably satisfactory in TRS-SCS, PRS-SCS, and SRS-SCS. In general, the reliability and validity of the study were satisfactory. Finally, the percentile rank and t-score norms were developed for 607 subjects in TRS-SCS, 1,168 subjects in PRS-SCS and 1,246 subjects in SRS-SCS.

    This paper reports on the development and validation of the Hong Kong Early Child Development Scale (HKECDS), a holistic measure of child development designed specifically for preschool children in Hong Kong. Scale development was an iterative process and the first version of the scale contained 190 items whereas the final version includes only 95. Children ranging in age from three to six years were administered trial versions of the HKECDS in Studies 1 (n = 60) and 2 (n = 240). Item analyses indicated that it is a developmental scale and that it has an appropriate level of difficulty for preschool children. It also discriminates between three- to six-year-olds from different social backgrounds in Hong Kong. The final version of the HKECDS includes items from the following eight subscales: Personal, Social and Self-Care (7 items), Language Development (13 items), Pre-academic Learning (27 items), Cognitive Development (10 items), Gross Motor (12 items), Fine Motor (9 items), Physical Fitness, Health and Safety (7 items), and Self and Society (10 items). The HKECDS is the first early child development scale which considers both the holistic development of preschool children and incorporates current expectations of early child development in Hong Kong. In this era of evidence-based decision making, it can be used to evaluate both the efficacy of targeted interventions and broader child-related public policies on early child development in Hong Kong.

    2014-04-01

    Contemporary research into science education has generally been conducted from the perspective of 'conceptual change' in learning. This study sought to extend previous work by recognizing that human rationality can be influenced by the emotions generated by the learning environment and specific actions related to learning. Methods used in educational psychology were adopted to investigate the emotional experience of science students as affected by gender, teaching methods, feedback, and learning tasks. A multidisciplinary research approach combining brain activation measurement with multivariate psychological data theory was employed in the development of a questionnaire intended to reveal the academic emotions of university students in three situations: attending science class, learning scientific subjects, and problem solving. The reliability and validity of the scale was evaluated using exploratory and confirmatory factor analyses. Results revealed differences between the genders in positive-activating and positive-deactivating academic emotions in all three situations; however, these differences manifested primarily during preparation for Science tests. In addition, the emotions experienced by male students were more intense than those of female students. Finally, the negative-deactivating emotions associated with participation in Science tests were more intense than those experienced by simply studying science. This study provides a valuable tool with which to evaluate the emotional response of students to a range of educational situations.

    Full Text Available Abstract Background Post-traumatic amnesia (PTA is a key symptom of traumatic brain injury (TBI. Accurate assessment of PTA is imperative in guiding clinical decision making. Our aim was to develop and externally validate a short, examiner independent and practical PTA scale, by selecting the most discriminative items from existing scales and using a three-word memory test. Methods Mild, moderate and severe TBI patients and control subjects were assessed in two separate cohorts, one for derivation and one for validation, using a questionnaire comprised of items from existing PTA scales. We tested which individual items best discriminated between TBI patients and controls, represented by sensitivity and specificity. We then created our PTA scale based on these results. This new scale was externally evaluated for its discriminative value using Receiver Operating Characteristic (ROC analysis and compared to existing PTA scales. Results The derivation cohort included 126 TBI patients and 31 control subjects; the validation cohort consisted of 132 patients and 30 controls. A set of seven items was eventually selected to comprise the new PTA scale: age, name of hospital, time, day of week, month, mode of transport and recall of three words. This scale demonstrated adequate discriminative values compared to existing PTA scales on three consecutive administrations in the validation cohort. Conclusion We introduce a valid, practical and examiner independent PTA scale, which is suitable for mild TBI patients at the emergency department and yet still valuable for the follow-up of more severely injured TBI patients.

    The aim of this study was to develop a self-diagnostic scale that could distinguish smartphone addicts based on the Korean self-diagnostic program for Internet addiction (K-scale) and the smartphone's own features. In addition, the reliability and validity of the smartphone addiction scale (SAS) was demonstrated. A total of 197 participants were selected from Nov. 2011 to Jan. 2012 to accomplish a set of questionnaires, including SAS, K-scale, modified Kimberly Young Internet addiction test (Y-scale), visual analogue scale (VAS), and substance dependence and abuse diagnosis of DSM-IV. There were 64 males and 133 females, with ages ranging from 18 to 53 years (M = 26.06; SD = 5.96). Factor analysis, internal-consistency test, t-test, ANOVA, and correlation analysis were conducted to verify the reliability and validity of SAS. Based on the factor analysis results, the subscale "disturbance of reality testing" was removed, and six factors were left. The internal consistency and concurrent validity of SAS were verified (Cronbach's alpha = 0.967). SAS and its subscales were significantly correlated with K-scale and Y-scale. The VAS of each factor also showed a significant correlation with each subscale. In addition, differences were found in the job (psmartphone addiction scores (psmartphone addiction aspect of the diagnostic manual. This scale was proven to be relatively reliable and valid.

Although effective, the existing Checklist required quantification and shortening to increase its utility, particularly as a longitudinal tool for measuring and communicating changes over time. 5 clinical experts, 3 people with epilepsy and 5 carers assessed the importance of each item on the ERAC questionnaire in a two-round Delphi survey. The refined Epilepsy Risk Awareness scale (ERA scale) was piloted in 30 patients to obtain an overall and sub-scale score for personal safety, health care, and quality of life domains, and was compared with the validated Seizure Severity Scale and Epilepsy Self-Management Scale. ERAC was shortened from 69 to 48 items to take 15-20min for completion. Pilot results showed good internal consistency for the overall ERA scale, for the Personal Safety and Health Care subscales, but less for the Quality of Life subscale. There was strong association between ERA scale and the Epilepsy Self-Management Scale, but little relationship with Seizure Severity Scale scores, which focus on individual seizures. User ratings were high. The ERA scale has been shortened and quantified to provide an objective measure of the risks and safety profile in people with epilepsy. The scale will be further tested for intra-rater variability and utility. Copyright © 2017 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    To develop a valid and reliable self-assessment scale that can be used by registered nurses in Taiwan to completely measure their patient education competence. The Patient Education Competence Scale for Registered Nurses was developed by using expert reviews, item analysis, exploratory factor analysis, criterion validity, and internal consistency and stability to test the construct validity and instrument stability. The exploratory factor analysis of the Patient Education Competence Scale for Registered Nurses from 133 responses revealed 24 items loading on two factors: implementation of patient education and preparation for patient education. The Patient Education Competence Scale for Registered Nurses correlated positively with the Clinical Teaching Competence Inventory. The Cronbach's alpha ranged from 0.96 to 0.97 and the test-retest reliability ranged from 0.82 to 0.88. The construct validity and internal consistency reliability of the Patient Education Competence Scale for Registered Nurses were supported. This scale reflected the characteristics of Taiwan's clinical nursing practice and it may be used to assess current patient education competence practice and the need for continuing education and study. However, additional research is needed to refine this scale and increase the possibility of generalizability. © 2016 Japan Academy of Nursing Science.

    Research suggests that patient uncertainty related to experiencing symptoms may drive decisions to seek care. The only validated measure of patient uncertainty assesses uncertainty related to defined illness. In prior work, we engaged patients to describe uncertainty related to symptoms and used findings to develop the 'U-Scale' scale. In this work, we present results from preliminary scale reliability and validity testing. Psychometric testing demonstrated content validity, high internal consistency, and evidence for concurrent validity. Next steps include administration in diverse populations for continued refinement and validation, and exploration of the potential contribution of uncertainty to healthcare utilization.

    There is a need for an appropriate instrument to measure colleague solidarity among nurses. This study was carried out to develop a Colleague Solidarity of Nurses' Scale (CSNS). This study was planned to be descriptive and methodological. The CSNS examined content validity, construct validity, test-retest reliability and internal consistency reliability. The trial form of the CSNS, which was composed of 44 items, was given to 200 nurses, followed by validity and reliability analyses. Following the analyses, 21 items were excluded from the scale, leaving an attitude scale made up of 23 items. Factor analysis of the data showed that the scale has a three sub-factor structure: emotional solidarity, academic solidarity and negative opinions about solidarity. The Cronbach's alpha reliability of the whole scale was 0.80. This study provides evidence that the CSNS possesses robust solidarity among nurses. © 2013 Wiley Publishing Asia Pty Ltd.

In addition, the reliability and validity of the smartphone addiction scale (SAS was demonstrated. METHODS: A total of 197 participants were selected from Nov. 2011 to Jan. 2012 to accomplish a set of questionnaires, including SAS, K-scale, modified Kimberly Young Internet addiction test (Y-scale, visual analogue scale (VAS, and substance dependence and abuse diagnosis of DSM-IV. There were 64 males and 133 females, with ages ranging from 18 to 53 years (M = 26.06; SD = 5.96. Factor analysis, internal-consistency test, t-test, ANOVA, and correlation analysis were conducted to verify the reliability and validity of SAS. RESULTS: Based on the factor analysis results, the subscale "disturbance of reality testing" was removed, and six factors were left. The internal consistency and concurrent validity of SAS were verified (Cronbach's alpha = 0.967. SAS and its subscales were significantly correlated with K-scale and Y-scale. The VAS of each factor also showed a significant correlation with each subscale. In addition, differences were found in the job (p<0.05, education (p<0.05, and self-reported smartphone addiction scores (p<0.001 in SAS. CONCLUSIONS: This study developed the first scale of the smartphone addiction aspect of the diagnostic manual. This scale was proven to be relatively reliable and valid.

  18. Scale up risk of developing oil shale processing units

    Oepik, I.

    1991-01-01

    The experiences in oil shale processing in three large countries, China, the U.S.A. and the U.S.S.R. have demonstrated, that the relative scale up risk of developing oil shale processing units is related to the scale up factor. On the background of large programmes for developing the oil shale industry branch, i.e. the $30 billion investments in colorado and Utah or 50 million t/year oil shale processing in Estonia and Leningrad Region planned in the late seventies, the absolute scope of the scale up risk of developing single retorting plants, seems to be justified. But under the conditions of low crude oil prices, when the large-scale development of oil shale processing industry is stopped, the absolute scope of the scale up risk is to be divided between a small number of units. Therefore, it is reasonable to build the new commercial oil shale processing plants with a minimum scale up risk. For example, in Estonia a new oil shale processing plant with gas combustion retorts projected to start in the early nineties will be equipped with four units of 1500 t/day enriched oil shale throughput each, designed with scale up factor M=1.5 and with a minimum scale up risk, only r=2.5-4.5%. The oil shale retorting unit for the PAMA plant in Israel [1] is planned to develop in three steps, also with minimum scale up risk: feasibility studies in Colorado with Israel's shale at Paraho 250 t/day retort and other tests, demonstration retort of 700 t/day and M=2.8 in Israel, and commercial retorts in the early nineties with the capacity of about 1000 t/day with M=1.4. The scale up risk of the PAMA project r=2-4% is approximately the same as that in Estonia. the knowledge of the scope of the scale up risk of developing oil shale processing retorts assists on the calculation of production costs in erecting new units.

    Park, Jin Beak

    1995-02-01

    Low-level radioactive waste management require the knowledge of the natures and quantities of radionuclides in the immobilized or packaged waste. U. S. NRC rules require programs that measure the concentrations of all relevant nuclides either directly or indirectly by relating difficult-to-measure radionuclides to other easy-to-measure radionuclides with application of scaling factors. Scaling factors previously developed through statistical approach can give only generic ones and have many difficult problem about sampling procedures. Generic scaling factors can not take into account for plant operation history. In this study, a method to predict plant-specific and operational history dependent scaling factors is developed. Realistic and detailed approach are taken to find scaling factors at reactor coolant. This approach begin with fission product release mechanisms and fundamental release properties of fuel-source nuclide such as fission product and transuranic nuclide. Scaling factors at various waste streams are derived from the predicted reactor coolant scaling factors with the aid of radionuclide retention and build up model. This model make use of radioactive material balance within the radioactive waste processing systems. Scaling factors at reactor coolant and waste streams which can include the effects of plant operation history have been developed according to input parameters of plant operation history

    Possible selves (PSs) have a significant role in adolescents' development. For this reason, it is of great importance to have adequate measures to operationalize them. The aim of this work is to present the construction and validation of a scale to assess PSs at the end of high school in multiple domains. Participants were adolescents (n = 320) of both sexes (female = 51.3%) from high-schools in Buenos Aires City, Argentina (age, M = 14.9, SD = 1.5). The scale was developed based on a literature review and a previous qualitative study. Expert judges' assessment revealed that it has good content validity. The scale's structure was studied with exploratory factor analysis and a 5-factor structure with theoretical meaning was found. Spearman's correlations between current and future self-perceptions show evidence of convergent validity. Mann-Whitney U test shows that the scale can discriminate by sex and age. The scale shows adequate to very good internal consistency. These results show that the scale has adequate psychometric properties to assess PSs in Argentine adolescents. The advantages of this scale relative to existing measures of PSs are discussed. Scale development allows us to know more about how adolescents think they will be during a significant life transition such as the end of high school. This is particularly important for planning interventions that focus on motivation and behavior regulation.

    1997-12-01

    The aim of the project is to develop production conditions, methods and technology of small-scale peat production to such a level that the productivity is improved and competitivity maintained. The aim in 1996 was to survey the present status of small-scale peat production, and research and development needs and to prepare a development plan for small-scale peat production for a continued project in 1997 and for the longer term. A questionnaire was sent to producers by mail, and its results were completed by phone interviews. Response was obtained from 164 producers, i.e. from about 75 - 85 % of small-scale peat producers. The quantity of energy peat produced by these amounted to 3.3 TWh and that of other peat to 265 000 m{sup 3}. The total production of energy peat (large- scale producers Vapo Oy and Turveruukki Oy included) amounted to 25.0 TWh in 1996 in Finland, of which 91 % (22.8 TWh) was milled peat and 9 % (2.2 TWh) of sod peat. The total production of peat other than energy peat amounted to 1.4 million m{sup 3}. The proportion of small-scale peat production was 13 % of energy peat, 11 % of milled peat and 38 % of sod peat. The proportion of small-scale producers was 18 % of other peat production. The results deviate clearly from those obtained in a study of small-scale production in the 1980s. The amount of small-scale production is clearly larger than generally assessed. Small-scale production focuses more on milled peat than on sod peat. The work will be continued in 1997. Based on development needs appeared in the questionnaire, the aim is to reduce environmental impacts and runoff effluents from small- scale production, to increase the efficiency of peat deliveries and to reduce peat production costs by improving the service value of machines by increasing co-operative use.

    2013-06-01

    Full Text Available In this paper, we report an inventory of leader behaviours that can promote creativity among R&D professionals. Specifically, we constructed and quantitatively validated a scale that was previously developed using a qualitative approach. We surveyed 584 scientists from 11 R&D laboratories in India. Exploratory and confirmatory factor analyses of the rating responses disclosed five leader behaviour factors: task-orientation; recognising and inspiring; empowering; team building and developing; and leading by example. Given acceptable evidence for convergent and discriminant validities of the factors, we argue for the use of this scale in future research in and management of creativity in R&D laboratories.

    The purpose of this research was to develop and partially assess a self-report scale for measuring doctors' and patients' perceptions of self-communication and other communication competence during a medical interview. Previous research into the components of communication competence and medical discourse were used to develop the Medical Communication Competence Scale (MCCS). It was hypothesized that the items of the MCCS would form four clusters: information giving, information seeking, information verifying, and socioemotional communication. The cluster analysis results provided support for the hypothesis. Results of several other analyses provided additional support for the validity of the MCCS.

    2013-07-01

    Scant research has examined customers as sources of workplace incivility, despite evidence suggesting that mistreatment is more common from organizational outsiders, including customers, than from organizational members (Grandey, Kern, & Frone, 2007; Schat & Kelloway, 2005). As an important step in extending the literature on customer incivility, we conducted two studies to develop and validate a measure of this construct. Study 1 used focus groups of retail and restaurant employees (n = 30) to elicit a list of uncivil customer behaviors, based on which we wrote initial scale items. Study 2 used a correlational survey design (n = 439) to pare down the number of scale items to 10 and to garner reliability and validity evidence for the scale. Exploratory and confirmatory factor analyses show that the scale is unidimensional and distinguishable from measures of the related, but distinct, constructs of interpersonal justice and psychological aggression from customers. Reliability analyses show that the scale is internally consistent. Significant correlations between the scale and individuals' job satisfaction, turnover intentions, and general and job-specific psychological strain provide evidence of criterion-related validity. Hierarchical regression analyses show that the scale significantly predicts three of four organizational and personal strain outcomes over and above a workplace incivility measure adapted for customer incivility, providing some evidence of incremental validity. Limitations and future research directions are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Robertson, Angela; Morse, David T; Hood, Kristina; Walker, Courtney

    Ample evidence exists in support of the influence of media, both traditional and electronic, on perceptions and engagement with alcohol marketing. We describe the development, calibration, and evidence for technical quality and utility for a new measure, the Alcohol Marketing Engagement Scale. Using two samples of college undergraduates (n1 = 199, n2 = 732), we collected field test responses to a total of 13 items. Initial support for scale validity is presented via correlations with attributes previously shown to be related to alcohol engagement. While the joint map of estimated scale locations of items and respondents indicates the need for further scale development, the results of the present analyses are promising. Implications for use in research are discussed.

  15. Development of a scale to measure individuals’ ratings of peace

    2014-01-01

    Background The evolving concept of peace-building and the interplay between peace and health is examined in many venues, including at the World Health Assembly. However, without a metric to determine effectiveness of intervention programs all efforts are prone to subjective assessment. This paper develops a psychometric index that lays the foundation for measuring community peace stemming from intervention programs. Methods After developing a working definition of ‘peace’ and delineating a Peace Evaluation Across Cultures and Environments (PEACE) scale with seven constructs comprised of 71 items, a beta version of the index was pilot-tested. Two hundred and fifty subjects in three sites in the U.S. were studied using a five-point Likert scale to evaluate the psychometric functioning of the PEACE scale. Known groups validation was performed using the SOS-10. In addition, test-retest reliability was performed on 20 subjects. Results The preliminary data demonstrated that the scale has acceptable psychometric properties for measuring an individual’s level of peacefulness. The study also provides reliability and validity data for the scale. The data demonstrated internal consistency, correlation between data and psychological well-being, and test-retest reliability. Conclusions The PEACE scale may serve as a novel assessment tool in the health sector and be valuable in monitoring and evaluating the peace-building impact of health initiatives in conflict-affected regions.

    Disruptive intraoperative behavior has detrimental effects to clinicians, institutions, and patients. How clinicians respond to this behavior can either exacerbate or attenuate its effects. Previous investigations of disruptive behavior have used survey scales with significant limitations. The study objective was to develop appropriate scales to measure exposure and responses to disruptive behavior. We obtained ethics approval. The scales were developed in a sequence of steps. They were pretested using expert reviews, computational linguistic analysis, and cognitive interviews. The scales were then piloted on Canadian operating room clinicians. Factor analysis was applied to half of the data set for question reduction and grouping. Item response analysis and theoretical reviews ensured that important questions were not eliminated. Internal consistency was evaluated using Cronbach α. Model fit was examined on the second half of the data set using confirmatory factor analysis. Content validity of the final scales was re-evaluated. Consistency between observed relationships and theoretical predictions was assessed. Temporal stability was evaluated on a subsample of 38 respondents. A total of 1433 and 746 clinicians completed the exposure and response scales, respectively. Content validity indices were excellent (exposure = 0.96, responses = 1.0). Internal consistency was good (exposure = 0.93, responses = 0.87). Correlations between the exposure scale and secondary measures were consistent with expectations based on theory. Temporal stability was acceptable (exposure = 0.77, responses = 0.73). We have developed scales measuring exposure and responses to disruptive behavior. They generate valid and reliable scores when surveying operating room clinicians, and they overcome the limitations of previous tools. These survey scales are freely available.

    Full Text Available Mokken (1971 developed a scaling procedure for both dichotomous and polytomous items that was later coined Mokken scale analysis (MSA. MSA has been developed ever since, and the developments until 2000 have been implemented in the software package MSP (Molenaar and Sijtsma 2000 and the R package mokken (Van der Ark 2007. This paper describes the new developments in MSA since 2000 that have been implemented in mokken since its first release in 2007. These new developments pertain to invariant item ordering, a new automated item selection procedure based on a genetic algorithm, inclusion of reliability coefficients, and the computation of standard errors for the scalability coefficients. We demonstrate all new applications using data obtained with a transitive reasoning test and a personality test.

  19. India's integrated child development services scheme: challenges for scaling up.

    Rao, N; Kaul, V

    2018-01-01

    India had around 158 million children under the age of 6 and about 26 million births in 2015. In the same year, India's Integrated Child Development Services Scheme served about 82 million children under 6 years and over 19 million pregnant women and lactating mothers. These 102 million beneficiaries received services in about 1.3 million centres. This paper reviews the growth of the Scheme and considers challenges to scaling up quality with equity based on results of large-scale national or multistate studies. The Scheme is associated with decreased malnutrition and better child development. The size and diversity of the country, the policy context, funding mode and lack of community awareness and engagement have hindered scaling up access while the approach to service delivery, low institutional capacity and poor infrastructure have impeded scaling up of implementation quality. This review illustrates the challenges associated with scaling-up access and implementation quality of a multicomponent, integrated early childhood programme in a large, diverse country. The future success of the Integrated Child Development Services will depend on how well it adheres to quality standards and how well it evolves to address current weaknesses. © 2017 John Wiley & Sons Ltd.

    2018-04-01

    Although there is a substantial body of work examining attitudes towards the police, no measure has been developed to consistently capture citizens' beliefs regarding police legitimacy. Given that police conduct has garnered a great deal of attention, particularly in the last few years, the current research sought to develop a scale measuring perceptions of police legitimacy. Across multiple studies, items were created and the scale's factor structure explored (Study 1 and Study 2), the factor structure was confirmed (Study 3a), and the predictive validity of the scale was tested (Studies 3b-3d). Results provided evidence for a reliable and valid 34-item scale with a single-factor solution that predicted multiple outcomes, including justification of a police shooting (Study 3b) and resource allocation to a police charity (Study 3c), as well as correlations with self-reported criminal activity, right-wing authoritarianism, and social dominance orientation (Study 3d). We hope this scale will be useful in the study of police legitimacy, expanding the current literature, and improving police-community relations.

  12. Heterogeneity and scale of sustainable development in cities.

    2017-08-22

    Rapid worldwide urbanization is at once the main cause and, potentially, the main solution to global sustainable development challenges. The growth of cities is typically associated with increases in socioeconomic productivity, but it also creates strong inequalities. Despite a growing body of evidence characterizing these heterogeneities in developed urban areas, not much is known systematically about their most extreme forms in developing cities and their consequences for sustainability. Here, we characterize the general patterns of income and access to services in a large number of developing cities, with an emphasis on an extensive, high-resolution analysis of the urban areas of Brazil and South Africa. We use detailed census data to construct sustainable development indices in hundreds of thousands of neighborhoods and show that their statistics are scale-dependent and point to the critical role of large cities in creating higher average incomes and greater access to services within their national context. We then quantify the general statistical trajectory toward universal basic service provision at different scales to show that it is characterized by varying levels of inequality, with initial increases in access being typically accompanied by growing disparities over characteristic spatial scales. These results demonstrate how extensions of these methods to other goals and data can be used over time and space to produce a simple but general quantitative assessment of progress toward internationally agreed sustainable development goals.

    2011-06-01

    Our aim was to develop a clinimetric scale evaluating motor phenomena, associated features, and severity of psychogenic nonepileptic seizures (PNES). Sixty video/EEG-recorded PNES induced by suggestion maneuvers were evaluated. We examined the relationship between results from this scale and results from the Clinical Global Impression (CGI) scale to validate this technique. Interrater reliabilities of the PNES scale for three raters were analyzed using the AC1 statistic, Kendall's coefficient of concordance (KCC), and intraclass correlation coefficients (ICCs). The relationship between the CGI and PNES scales was evaluated with Spearman correlations. The AC1 statistic demonstrated good interrater reliability for each phenomenon analyzed (tremor/oscillation, tonic; clonic/jerking, hypermotor/agitation, atonic/akinetic, automatisms, associated features). KCC and the ICC showed moderate interrater agreement for phenomenology, associated phenomena, and total PNES scores. Spearman's correlation of mean CGI score with mean total PNES score was 0.69 (Pscale described here accurately evaluates the phenomenology of PNES and could be used to assess and compare subgroups of patients with PNES.

    Utsumi, Shoka

    2013-08-01

    The present study developed the Parenting in Adolescence Scale (PAS) based on the three-factor model of parenting by Schaefer (1965), and examined its psychometric properties. Adolescents (n = 103 junior high, 273 high school and 667 university students) completed a questionnaire. Exploratory factor analysis identified three distinct factors labeled "Acceptance" (6 items), "Psychological control" (6 items) and "Parental monitoring" (3 items). Confirmatory factor analysis demonstrated the stability of the factor structure with adequate goodness of fit indices. The three subscales of PAS had adequate internal consistency and satisfactory test-retest reliability. The three scales also correlated significantly with measures of adolescent conduct problems, peer problems, risk-taking experience, prosocial behavior, self-esteem, and another parenting scale, which indicated construct and concurrent validity. The practical use of the PAS was discussed.

    2015-04-01

    We developed a free will and determinism scale in Japanese (FAD-J) to assess lay beliefs in free will, scientific determinism, fatalistic determinism, and unpredictability. In Study 1, we translated a free will and determinism scale (FAD-Plus) into Japanese and verified its reliability and validity. In Study 2, we examined the relationship between the FAD-J and eight other scales. Results suggested that lay beliefs in free will and determinism were related to self-regulation, critical thinking, other-oriented empathy, self-esteem, and regret and maximization in decision makings. We discuss the usefulness of the FAD-J for studying the psychological functions of lay beliefs in free will and determinism.

  1. The fractional scaling methodology (FSM) Part 1. methodology development

    2005-01-01

    Full text of publication follows: a quantitative methodology is developed, based on the concepts of hierarchy and synthesis, to integrate and organize information and data. The methodology uses scaling to synthesize experimental data and analytical results, and to provide quantitative criteria for evaluating the effects of various design and operating parameters that influence processes in a complex system such as a nuclear power plant or a related test facility. Synthesis and scaling are performed on three hierarchical levels: the process, component and system levels. Scaling on the process level determines the effect of a selected process on a particular state variable during a selected scenario. At the component level this scaling determines the effects various processes have on a state variable, and it ranks the processes according to their importance by the magnitude of the fractional change they cause on that state variable. At the system level the scaling determines the governing processes and corresponding components, ranking these in the order of importance according to their effect on the fractional change of system-wide state variables. The scaling methodology reveals on all levels the fractional change of state variables and is called therefore the Fractional Scaling Methodology (FSM). FSM synthesizes process parameters and assigns to each thermohydraulic process a dimensionless effect metric Ω = ωt, that is the product of the specific rate of fractional change ω and the characteristic time t. The rate of fractional change ω is the ratio of process transport rate over content of a preserved quantity in a component. The effect metric Ω quantifies the contribution of the process to the fractional change of a state variable in a given component. Ordering of a component effect metrics provides the hierarchy of processes in a component, then in all components and the system. FSM separates quantitatively dominant from minor processes and components and

  2. Development of the bullying and health experiences scale.

    Until recently, researchers have studied forms of bullying separately. For 40 years, research has looked at the traditional forms of bullying, including physical (eg, hitting), verbal (eg, threats), and social (eg, exclusion). Attention focused on cyberbullying in the early 2000s. Although accumulating research suggests that bullying has multiple negative effects for children who are targeted, these effects excluded cyberbullying from the definition of bullying. This paper responds to the need for a multidimensional measure of the impact of various forms of bullying. We used a comprehensive definition of bullying, which includes all of its forms, to identify children who had been targeted or who had participated in bullying. We then examined various ways in which they were impacted. We used an online method to administer 37 impact items to 377 (277 female, 100 male) children and youth, to develop and test the Bullying and Health Experience Scale. A principal components analysis of the bullying impact items with varimax rotation resulted in 8 factors with eigenvalues greater than one, explaining 68.0% of the variance. These scales include risk, relationships, anger, physical injury, drug use, anxiety, self-esteem, and eating problems, which represent many of the cognitive, psychological, and behavioral consequences of bullying. The Cronbach alpha coefficients for the 8 scales range from .73 to .90, indicating good inter-item consistency. Comparisons between the groups showed that children involved in bullying had significantly higher negative outcomes on all scales than children not involved in bullying. The high Cronbach alpha values indicate that the 8 impact scales provide reliable scores. In addition, comparisons between the groups indicate that the 8 scales provide accurate scores, with more negative outcomes reported by children involved in bullying compared to those who are not involved in bullying. This evidence of reliability and validity indicates that

    Literature shows that some health outcomes (e.g., eating, breathing, and speaking) are directly related to posture. Evidence of outcomes mediated by wheelchair seated posture is limited to interface pressure, physical function, and wheelchair skills and safety. This study's purpose was to develop and validate a rapid, low-burden, paper-pencil assessment of wheelchair seated posture for research use and to test feasibility of its use with a sample of older adults. We used a prospective design and a convenience sample of older adults who were receiving rehabilitation services in a community living center. Forty-nine older wheelchair users participated. Main measures were the Seated Posture Scale (SPS), Modified Ashworth Scale, Barthel Index, Visual Descriptor Scale, scale-content validity index (S-CVI), Cronbach alpha, and test-retest reliability. Rating by six experts yielded the overall content validity score (S-CVI) of 0.744. Total SPS score correlated positively with physical function (Barthel Index, r = 0.46, p Scale, r = -0.44, p = 0.001), supporting SPS construct validity. Internal consistency was 0.66 (Cronbach alpha). Test-retest reliability yielded Pearson product-moment correlations of 0.89 to 0.99. We conclude that the SPS has sufficient preliminary validity and reliability to support its use as an evaluation of wheelchair seated posture in outcomes research.

  6. Islam and Environmental Consciousness: A New Scale Development.

    Emari, Hossein; Vazifehdoust, Hossein; Nikoomaram, Hashem

    2017-04-01

    This research proposed a new construct, Islamic environmental consciousness (IEC), and developed a measurement scale to support this construct. Churchill's (J Mark Res 16(1):64-73, 1979) paradigm, adapted by Negra and Mzoughi (Internet Res 22(4):426-442, 2012), was utilized. A total of 32 items were generated based on the verses of the Qur'an from nine interviews with teachers in an Islamic seminary. This set of items was reduced to 19 after dropping redundant or non-representative items. In a pilot study, factor analysis of the 19-item scale yielded a two-factor structure scale of seven items with a reliability ranging from 0.7 to 0.8. The Islamic environmental consciousness scale (IECS) was statistically confirmed and validated in a subsequent investigation. The proposed measurement scale warrants further exploratory study. Future research should assess the IECS's validity across different Muslim countries, locales, and various Islamic schools of thought and practice. IEC is proposed as a new construct that focuses primarily on the Qur'an and seeks to achieve acceptance by both Sunni and Shia denominations. In this study, both cognitive attitudes and behavioral aspects were considered in the design of the IECS.

    Distrust of the health care system may be a significant barrier to seeking medical care, adhering to preventive health care and treatment regimens, and participating in medical research. To describe the development and psychometric testing of an instrument (the Health Care System Distrust Scale) to measure distrust of the health care system. Scale development involved 2 phases. In Phase 1, a pilot instrument was developed based on a conceptual model of health care-related distrust. Draft items were created using focus group sessions with members of the general public, literature review, and expert opinion. Draft items were pilot tested with 55 individuals waiting to be assigned to jury duty at the Municipal Court of Philadelphia. A priori, candidate items for elimination or revision included those with >5% missing data, extremely low or high interitem or item-total correlations, or those having a negative effect on the scale's internal consistency. In Phase 2, we conducted a survey of 400 prospective jurors to assess the reliability and validity of the final scale scores. In Phase 1, a 10-item scale was constructed that included 4 items measuring honesty, 2 items measuring confidentiality, 2 items measuring competence, and 2 items measuring fidelity. The participants in Phase 2 had a mean age of 41 years. Forty-three percent were African-American, 45% white, and 4% Hispanic. Scores on the Health Care System Distrust scale ranged from 12 to 46 with a possible range from 10 to 50. The mean score was 29.4 with a standard deviation of 6.33. No item had over 5% missing data. Internal consistency (Cronbach's alpha) was 0.75. Item-total correlations ranged from 0.27 to 0.57. Principal components analysis revealed 1 general component accounting for 32% of the variance. Nine of the variables had loadings higher than 0.40. As predicted, distrust of the health care system was higher among African Americans than whites and was inversely correlated with trust in personal

    To develop a new foot impact scale to assess foot status in rheumatoid arthritis (RA) using established qualitative methodology and the latest item response techniques (Rasch analysis). Foot problems in RA were explored by conducting qualitative interviews that were then used to generate items for a new foot impact scale. Further validation was undertaken following postal surveys and Rasch analysis. Analysis of the first postal survey (n = 192 responses) produced a 63-item binary response, 4-subscale instrument. The 4 subscales covered the domains impairment, activities, participation, and footwear. Following test-retest postal surveys and additional analysis, the instrument was reduced to a 2 subscale, 51-item questionnaire covering the domains of impairments/shoes and activities/participation. Initial results of these subscales indicate good psychometric properties, external validity, and test-retest reliability. A foot impact scale to assess the impact of RA and to measure the effect of interventions has been developed. The 2 scales comprising the instrument demonstrate good psychometric properties.

    Although numerous studies have been done on the topic ofjob satisfaction, as regards the Italian research, the construction of specific psychometric instruments is lacking. The present paper is aimed to develop a scale to measure job satisfaction referring to our cultural context. Participants were 222 workers (36.5% males, 63.5% females) with an average age of 38.39 years (SD = 10.91). The formulated items were selected from a large item pool on the basis of the evaluation by a group of expert judges, and the item analysis procedure. In order to establish test validity, the following instruments were also administered: Occupational Stress Indicator, Satisfaction With Life Scale, Rosenberg Self-Esteem Scale, Multidimensional Scale of Perceived Social Support, and Beck Depression Inventory. Both exploratory and confirmatory factor analyses highlighted a 6-factor structure. Those factors were responsible for 51.30% of the total variance. Reliability analyses indicated satisfying internal consistency (ranging from alpha = .73 to alpha = .86). Construct validity was supported by results obtained calculating correlations with the theoretically associated variables. Our findings suggest promising psychometric properties for the presented measure. The instrument could be used in specific programs developed to promote well-being conditions in work settings.

    To analyze neoplastic and hamartomatous variants of ameloblastic fibromas (AFs). Analysis of 172 cases (162 previously reported, 10 new). AF emerged as a lesion primarily of children and adolescents (mean age, 14.9 years), with about 80% diagnosed when odontogenesis is completed (age, 22 years are considered true neoplasms, while those in younger patients may be either true neoplasms or odontomas in early stages of development. Although the histopathology of hamartomatous and neoplastic variants of AF are indistinguishable, clinical and radiologic features can be of some help to distinguish between them. Asymptomatic small unilocular lesions with no or minimal bone expansion in young individuals are likely to be developing odontomas, and large, expansile lesions with extensive bone destruction are neoplasms.

  14. Interpreting "Personality" Taxonomies: Why Previous Models Cannot Capture Individual-Specific Experiencing, Behaviour, Functioning and Development. Major Taxonomic Tasks Still Lay Ahead.

    2015-12-01

    As science seeks to make generalisations, a science of individual peculiarities encounters intricate challenges. This article explores these challenges by applying the Transdisciplinary Philosophy-of-Science Paradigm for Research on Individuals (TPS-Paradigm) and by exploring taxonomic "personality" research as an example. Analyses of researchers' interpretations of the taxonomic "personality" models, constructs and data that have been generated in the field reveal widespread erroneous assumptions about the abilities of previous methodologies to appropriately represent individual-specificity in the targeted phenomena. These assumptions, rooted in everyday thinking, fail to consider that individual-specificity and others' minds cannot be directly perceived, that abstract descriptions cannot serve as causal explanations, that between-individual structures cannot be isomorphic to within-individual structures, and that knowledge of compositional structures cannot explain the process structures of their functioning and development. These erroneous assumptions and serious methodological deficiencies in widely used standardised questionnaires have effectively prevented psychologists from establishing taxonomies that can comprehensively model individual-specificity in most of the kinds of phenomena explored as "personality", especially in experiencing and behaviour and in individuals' functioning and development. Contrary to previous assumptions, it is not universal models but rather different kinds of taxonomic models that are required for each of the different kinds of phenomena, variations and structures that are commonly conceived of as "personality". Consequently, to comprehensively explore individual-specificity, researchers have to apply a portfolio of complementary methodologies and develop different kinds of taxonomies, most of which have yet to be developed. Closing, the article derives some meta-desiderata for future research on individuals' "personality".

Ensuring young breast cancer survivors receive patient-centered health information on the impact of treatment on fertility and fertility preservation options in a timely manner is a critical component of high quality nursing care. The objective of this manuscript is to report the process used to develop and examine the reliability and validity of an instrument to measure a breast cancer survivor’s self-assessed knowledge of fertility and fertility preservation.Design: A scale development and descriptive study.Setting: Online and global.Participants: Ninety-two young breast cancer survivors (ages 25–45 years.Methods: Participants completed the Knowledge of Fertility and Fertility Preservation (KF Scale as part of their participation in a larger study, the Fertility Cancer Project (FCP.Results: An exploratory factor analysis revealed five domains: normal reproductive function; general information about fertility; cancer treatment factors affecting fertility; infertility information; and alternative parenting options. A confirmatory factor analysis confirmed the validity of the construct with a demonstrated good fit between the factor structure of the new scale and the observed data. Many participants self-assessed their overall knowledge of fertility and fertility preservation as “a little” and the majority rated their knowledge of infertility information as “a little”.Conclusion: The KF Scale can be used to provide useful information to support health care professionals in the development of patient-centered education that is responsive to the unique needs of each young breast cancer survivor. The initial testing of the KF Scale indicates

    Decent work is positioned as the centerpiece of the recently developed Psychology of Working Theory (PWT; Duffy, Blustein, Diemer, & Autin, 2016). However, to date, no instrument exists which assesses all 5 components of decent work from a psychological perspective. In the current study, we developed the Decent Work Scale (DWS) and demonstrated several aspects of validity with 2 samples of working adults. In Study 1 (N = 275), a large pool of items were developed and exploratory factor analysis was conducted resulting in a final 15-item scale with 5 factors/subscales corresponding to the 5 components of decent work: (a) physically and interpersonally safe working conditions, (b) access to health care, (c) adequate compensation, (d) hours that allow for free time and rest, and (e) organizational values that complement family and social values. In Study 2 (N = 589), confirmatory factor analysis demonstrated that a 5-factor, bifactor model offered the strongest and most parsimonious fit to the data. Configural, metric, and scalar invariance models were tested demonstrating that the structure of the instrument did not differ across gender, income, social class, and majority/minority racial/ethnic groups. Finally, the overall scale score and 5 subscale scores correlated in the expected directions with similar constructs supporting convergent and discriminant evidence of validity, and subscale scores evidenced predictive validity in the prediction of job satisfaction, work meaning, and withdrawal intentions. The development of this scale provides a useful tool for researchers and practitioners seeking to assess the attainment of decent work among employed adults.

    Although the Modified Ashworth Scale is the most common instrument used to grade spasticity, it is unsuitable for busy follow-up clinics, longer term follow-up, or community surveys. To establish a simple questionnaire that would indicate the presence and extent of spasticity and would be suitable for use in everyday outpatient clinical practice and/or community follow-up. Qualitative exploration of the experience and impact of spasticity among stroke patients led to the development of a short questionnaire. Rasch analysis was performed on the data and the scale items were externally validated by correlation with comparator measures. Forty-eight subjects were recruited for the qualitative interviews, half of whom were more than 2 years post stroke. Interviews generated items relating to spasticity that were categorized into pain, spasm, fatigue, restricted movement, loss of balance, and altered appearance. Eight items were chosen for the draft questionnaire. Five hundred questionnaires were sent, and 188 (38%) were returned. The mean age of the 188 responders was 72.6 years. In regard to health, 18.5% reported that they were in good or excellent health, and 49.7% reported only fair or poor health. Data from the 8-item scale were fitted to the Rasch measurement model. Initial fit of the 8 items was good, and all the assumptions of the model were satisfied. A strong and significant gradient was found between the summed 8-item scale and self-reported health. A short self-perceived scale for spasticity has been developed from grounded theory, which satisfies the most rigorous standards for measurement with fit to the Rasch model.

    The interpersonal circumplex (IPC) is a well-established model of social behavior that spans basic personality and clinical science. Although several measures are available to assess interpersonal functioning (e.g., motives, traits) within an IPC framework, researchers studying interpersonal difficulties have relied primarily on a single measure, the Inventory of Interpersonal Problems-Circumplex Scales (IIP-C; Horowitz, Alden, Wiggins, & Pincus, 2000). Although the IIP-C is a widely used measure, it is currently the only measure specifically designed to assess maladaptive interpersonal behavior using the IPC framework. The purpose of the current study is to describe a new 64-item measure of interpersonal problems, called the Circumplex Scales of Interpersonal Problems (CSIP). Interpersonal problems derived from a pool of 400 personality-related problems were assessed in two large university samples. In the scale development sample (N = 1,197), items that best characterized each sector of the IPC were identified, and a set of eight 8-item circumplex scales was developed. Psychometric properties of the resulting measure were then examined in the validation sample (N = 757). Results from confirmatory circumplex structural analyses indicated that the CSIP fit well to a quasi-circumplex model. The CSIP converged with the IIP-C and the Revised Interpersonal Adjective Scales (Wiggins, 1995), and associated in theoretically expected ways with broader assessments of adaptive- and maladaptive-range personality traits and symptoms of psychological distress. The CSIP augments the IIP-C with additional content, thereby helping to extend the underlying constructs, and provides an alternative means for studying the interpersonal consequences of personality and psychopathology.

    Objective: To develop the Chinese primipara social capital scale (C-PSCS), and to evaluate its validity and reliability. Methods: The items of C-PSCS were developed based on Social Capital Scale by the World Bank and Social Network Scale. This scale was modified according to the characteristics of primiparas. We selected 10 experts who specialized in related field, and two rounds of seminars about content, cultural compatibility, primiparas' characteristics, and practicability. The finally C-PSCS included four dimensions: social trust, social reciprocity, social network, and social participation. Using purposive sampling to select 1 100 primiparas in their third trimesters (gestational weeks from 30 to 36 weeks). The validity analyses included content validity, construct validity and discriminant validity. The reliability analyses included Cronbach' α coefficient, and split-half reliability. Results: 1 035 questionnaires (94.09%) were qualified and the completion time was (13.23 ± 2.53) minutes. The total score of scale was 195.38 ± 45.98, and scores for social trust, social reciprocity, social network, and social participation were 30.26 ± 4.25, 22.84 ± 4.21, 34.23 ± 7.47, and 108.05 ± 41.96, respectively. The common factor cumulative variance contribution rates of each dimension were from 52.92% to 69.37%, which achieved more than 50% of the approved standard, and all the items held factor loading >0.5 in its relevant common factor, it had good construct validity. The scale had a good content validity, the r values between each dimensions and total scale were range from 0.57 to 0.81, Psocial trust, social reciprocity, social network, and social participation dimensions were 32.89±3.19, 25.65±3.48, 38.27±6.59, 119.94±36.61, respectively, which were higher than low-score group (27.77±3.58, 20.18±2.91, 30.40±6.13, 96.76 ± 43.60), t -values were -24.23, -27.46, -19.90, and -9.24, respectively, Psocial capital situation on the Chinese primiparas.

    2017-01-01

    Recent research has suggested that metacognitions may play a role across the spectrum of addictive behaviours. The goal of our studies was to develop the first self-report scale of metacognitions about online gaming. We conducted two studies with samples of online gamers (n=225, n=348) to test the structure and psychometric properties of the Metacognitions about Online Gaming Scale and examined its capacity to predict weekly online gaming hours and Internet addiction. Exploratory and confirmatory factor analyses supported a three-factor solution: positive metacognitions about online gaming, negative metacognitions about the uncontrollability of online gaming, and negative metacognitions about the dangers of online gaming. Internal consistency, predictive and divergent validity were acceptable. All the factors of the Metacognitions about Online Gaming Scale correlated positively with weekly online gaming hours and Internet addiction. Regression analyses showed that negative metacognitions about the uncontrollability of online gaming and levels of Internet addiction were the only significant predictors of weekly online gaming hours, and that positive metacognitions about online gaming and negative metacognitions about the uncontrollability of online gaming were the only significant predictors of Internet addiction. The Metacognitions about Online Gaming Scale was shown to possess good psychometric properties, as well as predictive and divergent validity within the populations that were tested.

    Walker, Arlene

    2010-08-01

    This paper builds on previous research by the author and describes the development and validation of a new measure of the psychological contract of safety. The psychological contract of safety is defined as the beliefs of individuals about reciprocal safety obligations inferred from implicit and explicit promises. A psychological contract is established when an individual believes that perceived employer and employee safety obligations are contingent on each other. A pilot test of the measure is first undertaken with participants from three different occupations: nurses, construction workers, and meat processing workers (N=99). Item analysis is used to refine the measure and provide initial validation of the scale. A larger validation study is then conducted with a participant sample of health care workers (N=424) to further refine the measure and to determine the psychometric properties of the scale. Item and correlational analyses produced the final employer and employee obligations scales, consisting of 21 and 17 items, respectively. Factor analyses identified two underlying dimensions in each scale comparable to that previously established in the organizational literature. These transactional and relational-type obligations provided construct validity of the scale. Internal consistency ratings using Cronbach's alpha found the components of the psychological contract of safety measure to be reliable. The refined and validated psychological contract of safety measure will allow investigation of the positive and negative outcomes associated with fulfilment and breach of the psychological contract of safety in future research. 2010 Elsevier Ltd.

    Full Text Available Beyond the rhetorical call for increasing patients’ engagement, policy makers recognize the urgency to have an evidence-based measure of patients’ engagement and capture its effect when planning and implementing initiatives aimed at sustaining the engagement of consumers in their health.In this paper, authors describe the Patient Health Engagement Scale (PHE-scale, a measure of patient engagement that is grounded in rigorous conceptualization and appropriate psychometric methods.The scale was developed based on our previous conceptualization of patient engagement (the PHE-model. In particular, the items of the PHE-scale were developed based on the findings from the literature review and from interviews with chronic patients. Initial psychometric analysis was performed to pilot test a preliminary version of the items. The items were then refined and administered to a national sample of chronic patients (N=382 to assess the measure’s psychometric performance. A final phase of test-retest reliability was performed.The analysis showed that the PHE Scale has good psychometric properties with good correlation with concurrent measures and solid reliability.Having a valid and reliable measure to assess patient engagement is the first step in understanding patient engagement and its role in health care quality, outcomes, and cost containment. The PHE Scale shows a promising clinical relevance, indicating that it can be used to tailor intervention and assess changes after patient engagement interventions.

  6. The Ambivalent Ageism Scale: Developing and Validating a Scale to Measure Benevolent and Hostile Ageism.

    Cary, Lindsey A; Chasteen, Alison L; Remedios, Jessica

    2017-04-01

    Much like sexism, ageism is a multifaceted prejudice; it involves benevolent and hostile attitudes toward older adults. There are many scales designed to measure hostile ageism, yet none dedicated to measuring benevolent ageism. In the current studies, we developed and validated a 13-item measure: the Ambivalent Ageism Scale (AAS). We employed four stages of scale development and validation. In Stage 1, we created 41 benevolent ageist items adapted from existing ageism measures. In Stages 2 and 3, we further refined the pool of items through additional testing and factor analysis and retained nine items loading strongly on two factors related to benevolent ageism: cognitive assistance/physical protection and unwanted help. In order to enable researchers to contrast benevolent and hostile attitudes, we then added four hostile ageist items. In Stage 4, we assessed the test-retest reliability of the 13-item scale. The AAS had good test-retest reliability (r = .80) and good internal consistency (α = .91). As predicted, the benevolent and hostile ageism subscales differentially predicted attitudes toward older adults: higher scores on the hostile subscale predicted lower competence and warmth ratings, whereas higher scores on the benevolent subscale predicted higher warmth perceptions. The AAS is a useful tool for researchers to assess hostile and benevolent ageism. This measure serves as an important first step in designing interventions to reduce the harmful effects of both hostile and benevolent ageism. © The Author 2016.

    2006-03-15

    The oil industry is currently facing severe restrictions concerning the discharge of oil field chemicals into the environment. Many commonly used materials in both topside and downhole applications are phased for substitution for use in the North Sea, and more will be identified. The development of biodegradable and low toxicity chemicals, which afford equal or improved efficacy, compared to conventional technology, available at a competitive price, is a current industry challenge. A range of biodegradable materials are increasingly available, however their limited performance can result in a restricted range of applications. This paper discusses the development and commercialization of a readily biodegradable scale inhibitor, ideal for use in topside applications. This material offers a broad spectrum of activity, notably efficiency against barium sulphate, calcium sulphate and calcium carbonate scales, in a range of water chemistries. A range of performance testing, compatibility, stability and OCNS dataset will be presented. Comparisons with commonly used chemicals have been made to identify the superior performance of this phosphate ester. This paper will discuss a scale inhibitor suitable for use in a variety of conditions which offers enhanced performance combined with a favourable biodegradation profile. This material is of great benefit to the industry, particularly in North Sea applications. (author) (tk)

    Social support is an important factor to consider in understanding the grief process. However, existing measures of social support fail to account adequately for the unique characteristics of grief experienced by healthcare workers in relation to the deaths of patients or nursing home residents. The purposes of this study were to develop and to test a grief support measure specific to the experiences of healthcare workers. Using a cross-sectional design, 380 nursing assistants completed self-administered surveys focusing on grief and loss in the nursing home setting. Exploratory factor analysis and regression analysis were conducted to test the psychometric properties of the Grief Support in Healthcare Scale (GSHCS) and to investigate the scale's relationships with grief outcomes. Reflective of the theory of disenfranchised grief, the 15 items of the GSHCS were loaded onto three distinct factors: recognition of the relationship, acknowledgement of the loss, and inclusion of the griever. Reliability was acceptable to high across these factors (Cronbach's α of .89, .86, and .78, respectively). Regression analysis indicated that the three subscales of the GSHCS were related significantly to both distress from grief and growth from grief, yet these relationships were unique for each factor. This research demonstrated that the GSHCS has acceptable reliability and face validity for understanding grief in healthcare workers and may aid in the development of interventions targeted at enfranchising grief in this population. Additional testing is needed to estimate the validity and the reliability of the scale with other groups of healthcare workers.

    This paper is a report of a study conducted to develop and test the psychometric properties of the Nurse-Physician Collaboration Scale. The importance of cooperation between healthcare professionals is widely acknowledged in Europe and the United States of America, but there have been no specific studies of interactions between healthcare professionals or of nurse-physician cooperation in Japan. The 51-item Nurse-Physician Collaboration Scale was developed using a process of item design, item refinement, and testing for reliability and validity. Random sampling was used to identify potential respondents from 27 of the 87 acute care hospitals in one city in Japan in 2006. Valid responses were obtained from 446 physicians and 1217 nurses (response rate 78.7% for nurses, and 54.4% for physicians). Construct validity was first confirmed by an exploratory factor analysis and then by a confirmatory factor analysis. Finally, a simultaneous analysis of several groups was performed. The test-retest method and Cronbach's alpha coefficients were used to assess reliability. Exploratory factor analysis yielded three factors. The three-factor models were confirmed by a confirmatory factor analysis (CFI >0.9, RMSEA test-retest reliability correlations were all 0.7 or above. Internal consistency was demonstrated by a Cronbach's alpha = 0.8 or above. The Nurse-Physician Collaboration Scale can be used to establish standards for nurse-physician collaboration, to measure the frequency of collaborative activity, and to verify unit-specific relationships between collaboration and quality of care.

    Although numerous research studies have been conducted to investigate apprehended child molesters' sexual interest in children and associated concepts, very little research has been conducted to investigate community males' sexual interest in children. In this article, the authors describe the development and preliminary validation of a new measure--the Interest in Child Molestation Scale--to assess community male's sexual arousal, behavioral propensity toward, and enjoyment of child sexual abuse. Preliminary results show that the Interest in Child Molestation Scale holds some promising psychometric properties, representing a reasonably reliable measure of community males' sexual interest in children. Using this scale, the authors find that a good proportion of community males (57%) did not emphatically reject an interest in child sexual abuse. The authors also find that self-reported sexual arousal to child sexual abuse that is relatively low in forcefulness was significantly related to implicit child sexualization as measured via a pen-and-paper implicit association test. The authors discuss these results with reference to possible future uses of the measure for theory and research development.

    Kindergarten education in Hong Kong serves children aged 32-68 months. However, there is no extant scale that measures kindergarten teachers' perceived work environment, an important influence on their well-being. To develop a new instrument, the Teachers' Perceived Work Environment (TPWE) scale, and to assess whether kindergarten teachers with higher TPWE ratings had higher scores for job satisfaction, self-esteem and mental health. A 25-item rating scale was developed and used with a sample of in-service kindergarten teachers. Their perceived work environment was represented by five factors (ergonomics, staffing, teaching space, work hours and social space). These teachers also completed three well-being inventories: the Job Satisfaction Survey, the Rosenberg Self-Esteem Inventory and the General Health Questionnaire-12. In a second stage, a new sample of in-service kindergarten teachers was used to cross-validate the findings from the earlier assessment. In the first sample of 141 teachers and the second of 125, social space, staffing and work hours were associated with job satisfaction, while ergonomics was a significant negative predictor of mental health complaints. The TPWE exhibited satisfactory reliability and validity. Some factors were differentially associated with specific types of well-being. The results may inform future studies of the working conditions of kindergarten teachers. © The Author 2015. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

    2013-12-01

    Full Text Available The terms "sustainable tourism," "ecotourism," "sustainable development," and "sustainability" have all been applied to various aspects of the global tourism industry to indicate that operators in those industries have accounted for the environmental, social, and economic impacts of their endeavors on the geographical regions within which they function. However, there has been increasing criticism that models for sustainable tourism do not account well for the long-term impacts of resort operations and how they scale in terms of local and regional economies, environmental footprint, and effect on local culture. The case of the Puntacana Ecological Foundation is cited here as a successful example of how locally focused, adaptive, and integrated sustainability efforts may provide useful models for the scaling of durable sustainable tourism activities in other regions and globally.

    The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies). In 11 independent studies (total N = 2,250), we demonstrate the SINS' psychometric properties. The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism. The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures.

    A new self-report measure of adolescent's self-presentation is described. The self-report scale was administered to 760 16-19-year-old subjects. Results of a factor analysis supported 6 identifiable factors reflecting different concepts, theoretically discussed, related to self-presentation: ability to regulate self-image, social sensitivity, body self-confidence, social self-confidence, social openness, and social desirability. The scale showed good convergent validity and internal consistency. Assertive tactics were predicted through ability to regulate self-image, social self-confidence, and social openness, whereas defensive tactics were predicted only through social openness and social sensitivity. The implications of the findings for future theoretical and empirical development of research in this field are discussed.

    Despite the increased social acceptance and widespread use of pornography over the past few decades, reliable and valid instruments assessing problematic use of pornography are lacking. This paper reports the findings of three studies aimed at developing and validating a new scale measuring problematic pornography use. The Problematic Pornography Use Scale (PPUS) items showed high internal consistency, convergent validity, and construct validity. Exploratory and confirmatory factor analyses revealed four core factors relating to proposed domains of problematic pornography use. High PPUS scores were positively correlated with measures of psychopathology, low self-esteem and poor attachment. Although PPUS scores were related to other behavioral addictions, problematic pornography use as operationalized in the current paper appears to be uniquely distinguished from features of behavioral addictions relating to gambling and Internet use. Findings highlight the potential use of the PPUS for future research and possible clinical applications by defining problematic pornography use as a behavioral addiction.

    2008-03-15

    This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at community-scale photovoltaics. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. The aim of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. This report provides examples of housing developments and incorporated townships that have integrated multiple stakeholder values into business solutions. The authors are of the opinion that builders, developers, architects and engineers need to consider orientation, aesthetics, load diversity, energy efficiency, grid infrastructure and end use. Residential and commercial building owners or occupants need to consider the design of electric services relative to loads, green image, and economic opportunities such as feed-in tariffs. Local government should give preference to granting permission to high-performance building projects. It is suggested that the finance and insurance sector consider the operational savings in overall debt allowances. System manufacturers and integrators should develop standardised systems. In the emerging PV community market, utilities are quickly gaining awareness of business opportunities. The need for professionals and skilled labour is quoted as having grown as drastically as the PV market itself.

    Full Text Available BackgroundThere is a growing concern in the field of aesthetic surgery about the need to measure patients' expectations preoperatively. The present study was designed to develop and validate the Expectations of Aesthetic Rhinoplasty Scale (EARS, and to compare expectations between rhinoplasty patients with and without body dysmorphic disorder (BDD.MethodsIn total, 162 college students and 20 rhinoplasty candidates were recruited. The measures included the newly developed EARS, a measure of psychopathology, and demographics. The DSM-IV structured clinical interview for BDD was used to confirm the diagnosis in rhinoplasty patients.ResultsThe EARS was constructed of six items based on their significant content validity. In the scale development phase, Cronbach's alpha was 0.87. The test-retest reliability coefficient of the scale was satisfactory (intraclass correlation coefficient, 0.94; 95% confidence interval, 0.82–0.98 over a four-week period. Scores on the EARS were significantly positively correlated with psychopathological symptoms (r=0.16; P<0.05. Moreover, comparison of EARS scores between BDD (M=25.90, standard deviation [SD]=6.91 and non-BDD rhinoplastic patients (M=15.70, SD=5.27 suggested that BDD patients held significantly higher expectations (P<0.01.ConclusionsThe expectations of aesthetic rhinoplasty patients toward surgery may play a crucial role in their postoperative satisfaction. While the value of patients' expectations is clinically recognized, no empirical study has measured these expectations in a psychometrically sound manner. The current study developed and validated the EARS. It may be easily used as a valid and reliable instrument in clinical and research settings.

SPT refers to the anxiety-related cognitive, emotional, and behavioral reactions to pain that resemble the features of a traumatic stress reaction.Methods: In Study 1, a preliminary set of 79 items was administered to 116 participants. The data were analyzed by using combined nonparametric and parametric item response theory resulting in a 12-item scale with a one-factor structure and good preliminary psychometric properties. Studies 2 and 3 assessed the factor structure and psychometric properties of the SPTS-12 in a community sample of 823 participants (268 with chronic pain and 555 pain-free and a clinical sample of 345 patients (126 with chronic post-surgical pain, 92 with other nonsurgical chronic pain, and 127 with no chronic pain at least 6 months after undergoing coronary artery bypass graft surgery, respectively. Results: The final SPTS-12 derived from Study 1 comprised 12 items that discriminated between individuals with different levels of SPT, with the overall scale showing good to very good reliability and validity. The results from Studies 2 and 3 revealed a one-factor structure for chronic pain and pain-free samples, excellent reliability and concurrent validity, and moderate convergent and discriminant validity. Conclusion: The results of the three studies provide preliminary evidence for the validity and reliability of the SPTS-12.

    The aim of this study was to develop a new scale, the Competence Scale for Senior Clinical Nurses (CS-SCN), to assess and evaluate senior clinical nurses in hospitals, and to confirm the validity and reliability of the scale. A cross-sectional questionnaire survey was undertaken at a hospital in Japan, using an anonymous self-administered questionnaire administered to clinical nurses (n=374). A useable sample of 218 was achieved, which was used in the analysis. Statistical analysis examined exploratory/confirmatory factor analysis, internal consistency, and construct validity. A five factor solution with 22 items was extracted for nursing competence in senior clinical nurses, which was the interpretable questionnaire. In the confirmatory factor analysis, the indices of fitness supported these results. Cronbach's alpha coefficient was 0.93 for the total score and varied between 0.63 and 0.90 in the five factors. Five factors emerged from an oblique factor analysis, with a cumulative variance of 66.7%: "role accomplishment"; "self-management"; "research"; "practice and coordination"; and "work implementation". The five factors had only a moderate correlation (0.30-0.77, Pcompetence of senior clinical nurses, was developed. Results suggest initial support for the new instrument as a measure of competence of senior clinical nurses, but it must be further refined, tested, and evaluated. Both the validity and reliability of the scale were verified. Future studies using the CS-SCN might lead to improvement in the competence of senior clinical nurses. © 2012 The Authors.

    1996-01-01

    Draper Laboratory, with its internal research and development budget, has for the past two years been funding a joint effort with the Massachusetts Institute of Technology (MIT) for the development of a large scale, high speed wheel test facility. This facility was developed to perform experiments and carry out evaluations on levitation and propulsion designs for MagLev systems currently under consideration. The facility was developed to rotate a large (2 meter) wheel which could operate with peripheral speeds of greater than 100 meters/second. The rim of the wheel was constructed of a non-magnetic, non-conductive composite material to avoid the generation of errors from spurious forces. A sensor package containing a multi-axis force and torque sensor mounted to the base of the station, provides a signal of the lift and drag forces on the package being tested. Position tables mounted on the station allow for the introduction of errors in real time. A computer controlled data acquisition system was developed around a Macintosh IIfx to record the test data and control the speed of the wheel. This paper describes the development of this test facility. A detailed description of the major components is presented. Recently completed tests carried out on a novel Electrodynamic (EDS) suspension system, developed by MIT as part of this joint effort are described and presented. Adaptation of this facility for linear motor and other propulsion and levitation testing is described.

    Full Text Available Body image is an important parameter of body satisfaction and needs to be evaluated with instruments developed and validated for a specific population. The aim of this study was to develop and validate a scale to assess body image in Brazilian women. A scale consisting of 11 silhouettes was prepared. Content validation was performed by seven experts from different health areas. To assess repeatability (two consecutive assessments and reproducibility (reassessment after one week, an intentional sample stratified into four groups according to the characterization of Brazilian women regarding nutritional status was selected. Participants were 125 women aged 18-55 years and body mass index (BMI between 18.5 and 38.6 kg/m2. The Kappa coefficient (k was used to assess repeatability and reproducibility, considering the isolated responses of the current body, ideal body and the difference between them, assumed as satisfactory when k≥0.6. For all trials, α=0.05. During the content validation phase, the instrument developed was changed following the evaluators’ suggestions and it was considered very suitable by six of seven evaluators. The Kappa coefficient was good in isolated issues and in the difference between them in both repeatability and reproducibility. The Body Image Scale was considered a valid content, with good repeatability and reproducibility. Considering the instrument as low cost and of rapid implementation/evaluation, it may be used to evaluate the body image of Brazilian women with BMI between 18.5 and 38.6 kg/m2, in different contexts.

    The current project sought to develop the Mexican Intercultural Competence Scale (MICS), which assesses group-specific skills and attributes that facilitate effective cultural interactions, among adults of Mexican descent. Study 1 involved an Exploratory Factor Analysis ( N = 184) that identified five factors including Ambition/Perseverance, Networking, the Traditional Latino Culture, Family Relationships, and Communication. In Study 2, a Confirmatory Factor Analysis provided evidence for the 5-factor model for adults of Mexican origin living in the Midwest ( N = 341) region of the U.S. The general findings are discussed in terms of a competence-based formulation of cultural adaptation and include theoretical and clinical implications.

    Although patient safety climate is an important factor in preventing adverse events in health care organizations, there is no usable Japanese scale. To develop a Japanese scale to measure patient safety climate and to evaluate its psychometric properties. Cross-sectional questionnaire survey was conducted with respect to 9 non-academic general hospitals in Japan. A total of 1878 health care professionals (nurses, therapists, technicians, pharmacists and physicians) were included in a study. The eight dimensions measuring worker attitudes (free communication flow, continuous improvement, reporting/rules compliance and patient/family involvement) and organizational factors (supervisors' safety leadership, allied professionals' safety leadership, patient safety committee leadership and rules/equipment availability) were extracted by factor analysis. The internal consistency (measured by Cronbach's alpha) and repeatability (measured by intraclass correlation) were more than 0.70 for all subscales. In addition, the mean score, the within-group interrater reliability statistic (r(wg)) and the correlation coefficients of the mean score were confirmed at the workplace level. The scale showed acceptable dimensionality, reliability and validity. It also provided workplace team-evaluation and a tool for assessing the patient safety climate at the level of the workplace.

    This study was done to develop the self-report Mother-Preschool Child Interaction Scale (MPIS) for mothers of preschool children. The scale was based on items derived from literature review and in-depth interviews. A methodological study was used to check reliability and validity and participants were 334 mothers of preschool children enrolled in kindergarten or nursery. Data were analyzed using principal component factor analysis for construct validity, t-test for contrasted group validity, Pearson correlation for criterion related validity and test-retest reliability and Cronbach's α for reliability. In the final MPIS 34 items identified through factor analysis were included, 6 constructs were derived, and explanatory power was 64.2%. Items on the MPIS were verified through correlation with the interaction observation scale of Kim & Mahoney and MPIS. Results were significant as mothers in the normal group exhibited MPIS scores that were significantly higher than those of mothers in the depressed group. Reliability of MPIS was .96 and test-retest reliability was .92. MPIS has the advantage of being easy to use, economical, and useful. Consequently, it is expected to be used as a screening tool for promptly and simply identifying the mother-preschool child interaction in diverse nursing practice and research.

    Full Text Available Abstract Background The concept of frailty, a relative state of weakness reflecting multiple functional and health domains, continues to receive attention within the geriatrics field. It offers a summary of key personal characteristics, providing perspective on an individual’s life course. There have been multiple attempts to measure frailty, some focusing on physiologic losses, others on specific diseases, disabilities or health deficits. Recently, multidimensional approaches to measuring frailty have included cognition, mood and social components. The purpose of this project was to develop and evaluate a Home Care Frailty Scale and provide a grounded basis for assessing a person’s risk for decline that included functional and cognitive health, social deficits and troubling diagnostic and clinical conditions. Methods A secondary analysis design was used to develop the Home Care Frailty Scale. The data set consisted of client level home care data from service agencies around the world. The baseline sample included 967,865 assessments while the 6-month follow-up sample of persons still being served by the home care agencies consisted of 464,788 assessments. A pool of 70 candidate independent variables were screened for possible inclusion and 16 problem outcomes referencing accumulating declines and clinical complications served as the dependent variables. Multiple regression techniques were used to analyze the data. Results The resulting Home Care Frailty Scale consisted of a final set of 29 items. The items fall across 6 categories of function, movement, cognition and communication, social life, nutrition, and clinical symptoms. The prevalence of the items ranged from a high of 87% for persons requiring help with meal preparation to 3.7% for persons who have experienced a recent decline in the amount of food eaten. Conclusions The interRAI Home Care Frailty Scale is based on a strong conceptual foundation and in our analysis, performed as

    Loneliness is a known risk factor for poor mental and physical health outcomes and quality of life in the general population, and preliminary research suggests that loneliness is linked to poorer health outcomes in cancer patients as well. Various aspects of the cancer experience contribute to patients feeling alone and misunderstood. Furthermore, loneliness theory suggests that negative social expectations, which may specifically relate to the cancer experience, precipitate and sustain loneliness. Cancer-specific tools are needed to assess key constructs of this theory. In the current study, we developed and tested measures of (1) loneliness attributed to cancer (i.e., cancer-related loneliness) and (2) negative social expectations related to cancer. First, we developed the items for the measures based on theory, prior research, and expert feedback. Next, we assessed the measures' psychometric properties (i.e., internal consistency and construct validity) in a diverse sample of cancer patients. The final products included a 7-item unidimensional Cancer Loneliness Scale and a 5-item unidimensional Cancer-related Negative Social Expectations Scale. Evidence of excellent reliability and validity was found for both measures. The resulting measures have both clinical and research utility.

    Full Text Available Following the abdominal surgery, extensive adhesions often occur and they can cause difficulties during laparoscopic operations. However, previous laparotomy is not considered to be a contraindication for laparoscopy. The aim of this study is to present that an insertion of Veres needle in the region of umbilicus is a safe method for creating a pneumoperitoneum for laparoscopic operations after previous laparotomy. In the last three years, we have performed 144 laparoscopic operations in patients that previously underwent one or two laparotomies. Pathology of digestive system, genital organs, Cesarean Section or abdominal war injuries were the most common causes of previouslaparotomy. During those operations or during entering into abdominal cavity we have not experienced any complications, while in 7 patients we performed conversion to laparotomy following the diagnostic laparoscopy. In all patients an insertion of Veres needle and trocar insertion in the umbilical region was performed, namely a technique of closed laparoscopy. Not even in one patient adhesions in the region of umbilicus were found, and no abdominal organs were injured.

    Obsessive–compulsive disorder (OCD) influences not only patients but also family members. Although the construct of family accommodation has received attention in OCD literature, no measures of overall family functioning are currently available. The OCD Family Functioning (OFF) Scale was developed to explore the context, extent, and perspectives of functional impairment in families affected by OCD. It is a three-part, self-report measure capturing independent perspectives of patients and relatives. A total of 400 subjects were enrolled between 2008 and 2010 from specialized OCD clinics and OCD research studies. Psychometric properties of this scale were examined including internal consistency, test–retest reliability, convergent and divergent validity, and exploratory factor analyses. Both patient and relative versions of the OFF Scale demonstrated excellent internal consistency (Cronbach’s alpha coefficient = 0.96). The test–retest reliability was also adequate (ICC = 0.80). Factor analyses determined that the OFF Scale comprises a family functioning impairment factor and four OCD symptom factors that were consistent with previously reported OCD symptom dimension studies. The OFF Scale demonstrated excellent convergent validity with the Family Accommodation Scale and the Work and Social Adjustment Scale. Information gathered regarding emotional impact and family role-specific impairment was novel and not captured by other examined scales. The OFF Scale is a reliable and valid instrument for the clinical and research assessment of family functioning in pediatric and adult OCD. This will facilitate the exploration of family functioning impairment as a potential risk factor, as a moderator and as a treatment outcome measure in OCD. PMID:21553962

    Full Text Available Abstract Background Route environments can be a potentially important factor in influencing people's behaviours in relation to active commuting. To better understand these possible relationships, assessments of route environments are needed. We therefore developed a scale; the Active Commuting Route Environment Scale (ACRES, for the assessment of bicyclists' and pedestrians' perceptions of their commuting route environments. Here we will report on the development and the results of validity and reliability assessments thereof. Methods Active commuters (n = 54 were recruited when they bicycled in Stockholm, Sweden. Traffic planning and environmental experts from the Municipality of Stockholm were assembled to form an expert panel (n = 24. The active commuters responded to the scale on two occasions, and the expert panel responded to it once. To test criterion-related validity, differences in ratings of the inner urban and suburban environments of Greater Stockholm were compared between the experts and the commuters. Furthermore, four items were compared with existing objective measures. Test-retest reproducibility was assessed with three types of analysis: order effect, typical error and intraclass correlation. Results There was a concordance in sizes and directions of differences in ratings of inner urban and suburban environments between the experts and the commuters. Furthermore, both groups' ratings were in line with existing objectively measured differences between the two environmental settings. Order effects between test and retest were observed in 6 of 36 items. The typical errors ranged from 0.93 to 2.54, and the intraclass correlation coefficients ranged from 'moderate' (0.42 to 'almost perfect' (0.87. Conclusions The ACRES was characterized by considerable criterion-related validity and reasonable test-retest reproducibility.

  12. Cluster policy and regional development: scale, scope and renewal

    Full Text Available Consistent with Marshallian/Porterian theories, the Norwegian cluster policy has been linked to the development of specialized regional industry environments. Cluster projects are relatively sector-specific entities often supporting (already strong regional industries and sectors. Following a review of the current literature on clusters and innovation, and informed by evolutionary thought, we argue that such constellations of specialized clusters may hamper the long-term innovation ability of regions. In a conceptual discussion of cluster evolution and its links to innovation and regional path renewal, we argue that special emphasis – both theoretical and political – has been placed on the geographical scale of clusters, but there has been less emphasis on scope. Accordingly, we present three theory-based strategies for cluster evolution and link these to regional development and innovation by assessing their impact on regional path renewal. We illustrate our argument empirically using examples from the Norwegian Centre of Expertise (NCE cluster programme.

  13. Tidal power plant may develop into large-scale industry

    2001-01-01

    Hammerfest was the first city in Norway with hydroelectric power production and the first city in Northern Europe to have electric street lights. Recently, technologists within the city's electricity supply industry have suggested that Hammerfest should pioneer the field of tidal energy. The idea is to create a new Norwegian large-scale industry. The technology is being developed by the company Hammerfest Stroem. A complete plant is planned to be installed in Kvalsundet. It will include turbine, generator, converters, transmission to land and delivery to the network. Once fully developed, in 2004, the plant will be sold. The company expects to install similar plants elsewhere in Norway and abroad. It is calculated that for a tidewater current of 2.5 m/s, the worldwide potential is about 450 TWh

    The concept of allometric growth is based on scaling relations, and it has been applied to urban and regional analysis for a long time. However, most allometric analyses were devoted to the single proportional relation between two elements of a geographical system. Few researches focus on the allometric scaling of multielements. In this paper, a process of multiscaling allometric analysis is developed for the studies on spatio-temporal evolution of complex systems. By means of linear algebra, general system theory, and by analogy with the analytical hierarchy process, the concepts of allometric growth can be integrated with the ideas from fractal dimension. Thus a new methodology of geo-spatial analysis and the related theoretical models emerge. Based on the least squares regression and matrix operations, a simple algorithm is proposed to solve the multiscaling allometric equation. Applying the analytical method of multielement allometry to Chinese cities and regions yields satisfying results. A conclusion is reached that the multiscaling allometric analysis can be employed to make a comprehensive evaluation for the relative levels of urban and regional development, and explain spatial heterogeneity. The notion of multiscaling allometry may enrich the current theory and methodology of spatial analyses of urban and regional evolution.

    Messages from organizations with high, compared to low, credibility may be more persuasive. Whereas the tobacco industry has long recognized the importance of credibility in promoting its messages and public image, the source credibility of key tobacco control organizations has gone largely unmeasured. To assess credibility of a key tobacco regulator, we developed a scale of the US Food and Drug Administration (FDA) tobacco-related credibility. We developed and tested 30 items reflective of the dimensions of source credibility (trust, expertise, and public interest) and FDA's tobacco regulatory roles in a sample of 1353 US adults and assessed reliability and validity. Factor analysis identified 3 dimensions of the FDA Tobacco Credibility Scale (FDA-TCS): public interest, trust, and expertise. The 3 subscales showed evidence of reliability and convergent validity; all subscales were correlated with general FDA credibility and trust in government. Those who knew that the FDA regulates tobacco scored higher on the trust and expertise subscales. The subscales were also associated with support for potential regulations, suggesting criterion-related validity. The FDA-TCS allows for an understanding of the impact of credibility on responses to the FDA's tobacco control communications and regulatory efforts.

    Full Text Available The ontogeny of large-scale functional organization of the human brain is not well understood. Here we use network analysis of intrinsic functional connectivity to characterize the organization of brain networks in 23 children (ages 7-9 y and 22 young-adults (ages 19-22 y. Comparison of network properties, including path-length, clustering-coefficient, hierarchy, and regional connectivity, revealed that although children and young-adults' brains have similar "small-world" organization at the global level, they differ significantly in hierarchical organization and interregional connectivity. We found that subcortical areas were more strongly connected with primary sensory, association, and paralimbic areas in children, whereas young-adults showed stronger cortico-cortical connectivity between paralimbic, limbic, and association areas. Further, combined analysis of functional connectivity with wiring distance measures derived from white-matter fiber tracking revealed that the development of large-scale brain networks is characterized by weakening of short-range functional connectivity and strengthening of long-range functional connectivity. Importantly, our findings show that the dynamic process of over-connectivity followed by pruning, which rewires connectivity at the neuronal level, also operates at the systems level, helping to reconfigure and rebalance subcortical and paralimbic connectivity in the developing brain. Our study demonstrates the usefulness of network analysis of brain connectivity to elucidate key principles underlying functional brain maturation, paving the way for novel studies of disrupted brain connectivity in neurodevelopmental disorders such as autism.

The instrument is a 12-item self-report instrument, developed in the Scandinavian cultural context and based on Kohlberg’s theory. A hypothesized simplex structure model underlying the MDSP was tested through structural equation modeling. Validity was also tested as the proportion of respondents older than 20 years that reached the highest moral level, which according to the theory should be small. A convenience sample of 339 nursing students with a mean age of 25.3 years participated. Results confirmed the simplex model structure, indicating that MDSP reflects a moral construct empirically organized from low to high. A minority of respondents >20 years of age (13.5% scored more than 80% on the highest moral level. The findings support the construct validity of the MDSP and the stages and levels in Kohlberg’s theory.Keywords: Kohlberg, scale testing, simplex structure model, structural equation modeling

    The purpose of this study was to develop a measurement tool of nurse's turnover intention. Data were collected from questionnaires completed by 678 nurses who worked in 3 university hospitals in South Korea and analyzed using the SPSS 18.0 and AMOS 18 programs. Thirty-seven preliminary items were selected from 161 basic items extracted via a literature review and in depth interviews with 6 hospital nurses. Three steps with factor analysis were undertaken to verify the reliability and validity of the preliminary instruments. Finally, confirmative factor analysis was carried out. As a result of the analysis, 3 factors including 10 items were selected. Cronbach's Alpha for the 10 items was .83, for job satisfaction (4 items), .78, for interpersonal relationships (3 items), .80, and for work performance (3 items), .74, which was stable. This study is meaningful because through it a scale reflecting Korean culture was developed to measure turnover intention in nurses. Further studies that test the psychometrics of this scale in more diverse samples are warranted.

    Stress-related eating has long been a focus of study in several disciplines. Currently available psychometric scales conflate stress-related eating with emotional eating despite that not all stress states can be subsumed under some form of specific emotion. Moreover, existing measures primarily assess increased food intake in response to emotions and stress, thus ignoring evidence of decreased food intake in response to stress. Therefore, we drew from established stress concepts to develop the first genuine stress-related eating scale (Salzburg Stress Eating Scale [SSES]) in both German and English versions. In the SSES higher scores indicate eating more when stressed and lower scores indicate eating less when stressed. In study 1 (n = 340), the German SSES was found to have a one-factor structure (α = 0.89). SSES scores were weakly or moderately correlated with other eating-related constructs (e.g., emotional eating, body mass index [BMI]), and weakly correlated or uncorrelated with non-eating-related constructs (e.g., impulsivity, perceived stress); in addition, women had higher scores than men. Perceived stress moderated the association between stress eating and BMI, such that higher SSES scores were significantly related to higher BMI in individuals with high perceived stress, but not in individuals with low perceived stress. In studies 2 (n = 790) and 3 (n = 331), factor structure, internal consistency, and associations with sex and BMI were replicated for both German and English versions of the SSES. Hence, the SSES represents a psychometrically sound tool for the measurement of stress-related eating. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Objectives This study was conducted to develop a scale for measuring "attachment to the local community" for its use in health services. The scale is also intended to nurture new social relationships in late middle-aged individuals.Methods Thirty items were initially planned to be included in the scale to measure "attachment to the local community", according to a previous study that identified the concept. The study subjects were late middle-aged residents of City B in Prefecture A, located in Tokyo suburbs. From the basic resident register data, 1,000 individuals (local residents in the 50-69 year age group) were selected by a multi-stage random sampling technique, on the basis of their residential area, age, and sex (while maintaining the male to female ratio). An unsigned self-administered questionnaire was distributed to the subjects, and the responses were collected by postal mail. The collected data was analyzed using psychometric study of scale.Results Valid responses were obtained from 583 subjects, and the response rate was 58.3%. In an item analysis, none of the items were rejected. In a subsequent factor analysis, 7 items were eliminated. These items included 2 items with a factor loading of vitality to live life," "Intention to cherish ties with people," "Place where one can be oneself," and "Pride of being a resident." Cronbach's coefficient α for the entire scale of "attachment to the local community" was 0.95, demonstrating internal consistency. We then examined the correlation with an existing scale to measure social support; the results revealed a statistically significant correlation and confirmed criterion-related validity (P<0.001). In addition, the fit indices in a covariance structure analysis showed adequate values.Conclusions The developed scale was considered reliable and appropriate for measuring "attachment to the local community."

    During the R and D phase of the Superconducting Supercollider (SSC) program, LBL was responsible for establishing the parameters for cables used in SSC dipole and quadrupole magnets. In addition, LBL has collaborated with Fermi National Accelerator Laboratory on the design and fabrication of a new cable for use in the Low Beta Quadrupoles. As a result of the development work on these and other cables, we have arrived a set of scaling rules which provide guidelines for choosing the parameters for a wide range of superconducting cables. These parameters include strand size, strand number, keystone angle, percent compaction, cable pitch and compacted cable dimensions. In addition, we have defined the tolerance ranges for the key cable manufacturing parameters such as mandrel size and shape, strand tension, and Turkshead temperature control. In this paper, the authors present the results on cables ranging from 8 strands to 36 strands of 0.65mm wire and from 8 strands to 30 strands of 0.8mm wire. The authors use these results to demonstrate the application of the scaling rules for Rutherford-type cable

    Full Text Available MAIN OBJECTIVES: The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS. Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies. METHODS: In 11 independent studies (total N = 2,250, we demonstrate the SINS' psychometric properties. RESULTS: The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults, intrapersonal correlates (e.g., positive affect, depression, and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior. The SINS taps into the more fragile and less desirable components of narcissism. SIGNIFICANCE: The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures.

    The objective of this study was to develop a short and reliable Family Dynamic Environment Scale (FDES) that would better serve the needs of mental health professionals in detecting the potential for delinquent behavior in Korean adolescents related to a dysfunctional family dynamic environment. Semi-structured interviews with 30 adolescents were initially conducted to generate a set of items, after which, 44 participants were included in method test-retest reliability test. Finally, 544 participants recruited by proportional stratified random sampling were included in a factor analysis. The original version of the FDES had 60 items in 7 categories; the final version included 42 items grouped into 5 factors. Both test-retest reliability and Cronbach's alpha coefficient were high for the final version of the scale. As a result of factor analysis, five factors were extracted: family psychological climate, parent-child relationship, paternal parenting attitude, family cohesion, and maternal parenting attitude. These contributed 50.3% of the variance in the item scores. All 42 items loaded above .35 on their respective factors. The Cronbach's alpha coefficients for internal consistency were .95 for the total 42 items and .92, .81, .82, .78, and .71, respectively, for each of the 5 factors.

    In this study, two units of personal computer were successfully networked together to form a small scale cluster. Each of the processor involved are multicore processor which has four cores in it, thus made this cluster to have eight processors. Here, the cluster incorporate Ubuntu 14.04 LINUX environment with MPI implementation (MPICH2). Two main tests were conducted in order to test the cluster, which is communication test and performance test. The communication test was done to make sure that the computers are able to pass the required information without any problem and were done by using simple MPI Hello Program where the program written in C language. Additional, performance test was also done to prove that this cluster calculation performance is much better than single CPU computer. In this performance test, four tests were done by running the same code by using single node, 2 processors, 4 processors, and 8 processors. The result shows that with additional processors, the time required to solve the problem decrease. Time required for the calculation shorten to half when we double the processors. To conclude, we successfully develop a small scale cluster computer using common hardware which capable of higher computing power when compare to single CPU processor, and this can be beneficial for research that require high computing power especially numerical analysis such as finite element analysis, computational fluid dynamics, and computational physics analysis.

    Despite a growing recognition of cultural connectedness as an important protective factor for First Nations (FN) peoples' health, there remains a clear need for a conceptual model that organizes, explains, and leads to an understanding of the resiliency mechanisms underlying this concept for FN youth. The current study involved the development of the Cultural Connectedness Scale (CCS) to identify a new scale of cultural connectedness. A sample of 319 FN, Métis, and Inuit youths enrolled in Grades 8-12 from reserve and urban areas in Saskatchewan and Southwestern Ontario, Canada, participated in the current study. A combination of rational expert judgments and empirical data were used to refine the pool of items to a set that is a representative sample of the indicators of the cultural connectedness construct. Exploratory factor analysis (EFA) was used to examine the latent structure of the cultural connectedness items, and a confirmatory factor analysis was used to test the fit of a more parsimonious version of the final EFA model. The resulting 29-item inventory consisted of 3 dimensions: identity, traditions, and spirituality. Criterion validity was demonstrated with cultural connectedness dimensions correlating well with other youth well-being indicators. The conceptualization and operationalization of the cultural connectedness has a number of potential applications both for research and prevention. This study provides an orienting framework that guides measurement of cultural connectedness that researchers need to further explore the role of culture in enhancing resiliency and well-being among FN youth in Canada. 2015 APA, all rights reserved

    Full Text Available This study developed and validated a new measure to assess the death anxiety (i.e., Scale of Death Anxiety, SDA on an individual’s somatic, cognitive, emotional, and behavioral reactions from a symptomatic perspective in Chinese youth samples. Following a systematic process, a four-factor structure of the SDA was identified through principle components analysis and confirmatory factor analysis that revealed four aspects of death anxiety: Dysphoria, Death Intrusion, Fear of Death, and Avoidance of Death. The results of this study indicate that the SDA has a clear factor structure and good psychometric properties. The SDA supports death anxiety as a multidimensional construct, and the foundational role of fear of death in the generation of death anxiety. This scale is valuable and beneficial to research on death anxiety. This study makes a significant contribution to the literature because the SDA is the first assessment of death anxiety to include the constructs of dysphoria and somatic symptoms. And the potential clinical practice of the SDA was discussed.

    The aim of the present study was to develop a valid and reliable Videogame Addiction Scale for Children (VASC). The data were derived from 780 children who completed the Videogame Addiction Scale (405 girls and 375 boys; 48.1% ranging in age from 9 to 12 years). The sample was randomly split into two different sub-samples (sample 1, n  = 400; sample 2, n  = 380). Sample 1 was used to perform exploratory factor analysis (EFA) to define the factorial structure of VASC. As a result of EFA, a four-factor structure comprising 21 items was obtained and explained 55% of the total variance (the four factors being "self-control," "reward/reinforcement," "problems," and "involvement"). The internal consistency reliability of VASC has found 0.89. Confirmatory factor analysis (CFA) was performed to confirm the factorial structure obtained by EFA in the remaining half of sample ( n  = 390). The obtained fit indices from the CFA confirmed the structure of the EFA. The 21-item VASC has good psychometric properties that can be used among Turkish schoolchildren populations.

    The movement to use empirically supported treatments has increased the need for researchers and supervisors to evaluate therapists' adherence to and the quality with which they implement those interventions. Few empirically supported approaches exist for providing these types of evaluations. This is also true for motivational interviewing, an empirically supported intervention important in the addictions field. This study describes the development and psychometric evaluation of the Motivational Interviewing Supervision and Training Scale (MISTS), a measure intended for use in training and supervising therapists implementing motivational interviewing. Satisfactory interrater reliability was found (generalizability coefficient p(2) = .79), and evidence was found supporting the convergent and discriminant validity of the MISTS. Recommendations for refinement of the measure and future research are discussed. ((c) 2005 APA, all rights reserved).

    Transgender-inclusive behaviors are actions and communication supporting transgender individuals. Examples include using language not reinforcing the gender binary, asking for and using correct pronouns, creation of spaces that welcome members of the transgender community, and acknowledging cisgender (non-transgender) privilege. A survey was developed measuring this behavior in individuals to examine the impact of transgender-inclusive behavior and the potential effect of interventions on promoting inclusive behavior. Data were collected utilizing an online survey (N = 1,051). The sample was split in half to run two sets of cases in a principal components analysis. Analysis of the full sample showed Cronbach's alpha to be .93 (n = 918). Findings suggest that the Transgender Inclusive Behavior Scale (TIBS) may be a useful instrument for identifying behaviors related to being inclusive of transgender individuals, groups, and communities. It may also be used to measure behavior change before and after transgender-specific educational and behavioral interventions.

    Development of a valid, reliable instrument to measure spiritual self-care practices of patients with heart failure. African American patients (N = 142) with heart failure participated in the study. Spiritual advisors from several religious groups reviewed the Spiritual Self-Care Practices Scale (SSCPS) for content validity. Construct validity was determined using a principal components factor analysis. Reliability was established using Cronbach's alpha coefficients. Religious advisors provided suggestions to improve content validity. Four factors consistent with spiritual practices (personal spiritual practices, spiritual practices, physical spiritual practices, and interpersonal spiritual practices) emerged from the factor analysis. The alpha coefficient was moderate at 0.64. Results indicated the SSCPS was reliable and valid for measuring spiritual self-care practices among African Americans with heart failure. Additional testing is needed to confirm results in other patient groups with chronic illnesses.

Sample 1 (N = 421) was used for EFA to select items for the Perceived Standards from God (5 items) and the Perceived Discrepancy from God (5 items) subscales. Sample 2 (N = 420) was used for CFA and cross-validated the 2-factor oblique model as well as a bifactor model. Perceived Standards from God scores had Cronbach alphas ranging from .73 to .78, and Perceived Discrepancy from God scores had Cronbach alphas ranging from .82 to .84. Standards from God scores were positively correlated with positive affect, whereas Discrepancy from God scores was positively correlated with negative affect, shame and guilt. Moreover, these two PPGS subscale scores added significant incremental variances in predicting associated variables over and above corresponding personal perfectionism scores.

    Four studies were conducted to develop and validate the Sexual Assertiveness Scale (SAS), a measure of sexual assertiveness in women that consists of factors measuring initiation, refusal, and pregnancy-sexually transmitted disease prevention assertiveness. A total of 1,613 women from both university and community populations were studied. Confirmatory factor analyses demonstrated that the 3 factors remained stable across samples of university and community women. A structural model was tested in 2 samples, indicating that sexual experience, anticipated negative partner response, and self-efficacy are consistent predictors of sexual assertiveness. Sexual assertiveness was found to be somewhat related to relationship satisfaction, power, and length. The community sample was retested after 6 months and 1 year to establish test-retest reliability. The SAS provides a reliable instrument for assessing and understanding women's sexual assertiveness.

    Sexual contingent self-worth (CSW) refers to self-worth that is dependent on maintaining a sexual relationship, and has not been studied previously. This novel construct may have implications for sexual, relationship, and psychological well-being, because it could affect the cognitions, affect, and behaviors of individuals in sexual relationships. The purpose of this study was to develop the Sexual Contingent Self-Worth Scale and examine its reliability and validity in community samples. Two separate online studies (N = 329 and N = 282) included men and women who were in committed, sexually active relationships. The Sexual CSW Scale was adapted from a validated measure of relationship CSW. In Study 1, participants completed the Sexual CSW Scale, whereas in Study 2, participants also responded to standardized measures of related constructs. In addition, participants completed the Sexual CSW Scale again two weeks later in Study 2. Factor analysis yielded two subscales: (a) sexual CSW dependent on positive sexual events in the relationship and (b) sexual CSW dependent on negative sexual events. Results indicated good construct validity, incremental validity, internal consistency, and test-retest reliability for the Sexual CSW Scale. This research contributes to the fields of both CSW and sexuality by introducing a novel domain of CSW.

    To report a pilot study for the development and validation of an instrument to measure quality in historical research papers. There are no set criteria to assess historical papers published in nursing journals. A three phase mixed method sequential confirmatory design. In 2012, we used a three-phase approach to item generation and content evaluation. In phase 1, we consulted nursing historians using an online survey comprising three open-ended questions and revised the items. In phase 2, we evaluated the revised items for relevance with expert historians using a 4-point Likert scale and Content Validity Index calculation. In phase 3, we conducted reliability testing of the instrument using a 3-point Likert scale. In phase 1, 121 responses were generated via the online survey and revised to 40 interrogatively phrased items. In phase 2, five items with an Item Content Validity Index score of ≥0·7 remained. In phase 3, responses from historians resulted in 100% agreement to questions 1, 2 and 4 and 89% and 78%, respectively, to questions 3 and 5. Items for the QSHRP have been identified, content validated and reliability tested. This scale improves on previous scales, which over-emphasized source criticism. However, a full-scale study is needed with nursing historians to increase its robustness. © 2014 John Wiley & Sons Ltd.

  1. Developing Affective Mental Imagery Stimuli with Multidimensional Scaling

    2015-06-01

    Full Text Available The goal of this paper is to provide an example of how multidimensional scaling (MDS can be used for stimuli development. The study described in this paper illustrates this process by developing affective mental imagery stimuli using the circumplex model of affect as a guide. The circumplex model of affect argues that all emotions can be described in terms of two underlying primary dimensions: valence and arousal (Russel, 1980. We used MDS to determine if affective mental imagery stimuli obtained from verbal prompts could be separated by arousal and valence to create four distinct categories (high –positive, low-positive, high-negative, and low-negative as seen in other stimuli. 60 students from the University of South Carolina participated in the first experiment to evaluate three sets of stimuli. After being analyzed using MDS, selected stimuli were then assessed again in a second experiment to validate their robust valence and arousal distinctions. The second experiment was conducted with 34 subjects to validate 40 of the best stimuli from experiment 1. It was found that mental imagery stimuli can produce a reliable affective response for the dimensions of valence and arousal and that MDS can be an effective tool for stimuli development.

    Full Text Available Abstract Background Although public health concerns have been raised regarding the detrimental health effects of increasing rates of electronic screen use among adolescents, such effects have been small. Instruments currently available tend to be lengthy, have a clinical research focus, and assess young people’s screen use on specific screen-based activities (e.g., TV, computer, or internet. None appear to address screen use across a broad range of screens, including mobile devices and screen-based activities. The objective was to develop a new and short self-report scale for investigating adolescents’ screen use across all screens and screen-based activities in non-clinical settings. Methods The Adolescent Preoccupation with Screens Scale (APSS was developed over a three stage process. First, a review of the current literature and existing instruments was undertaken and suitable items identified. Second, the draft APSS was piloted with adolescents and item affectivity and discrimination indices were calculated. Third, a cross sectional school based online survey of 1967 Australian adolescents in grades 5 (10 years old, 7 (13 years and 9 (15 years from 25 randomly selected schools was conducted. Results Factor Analysis on a sub-sample of the data (n = 782 and Confirmatory Factor Analysis on the remaining sub-sample (n = 1185, supported a two-factor model. The first factor reflects adolescents’ mood management with screen use, and the second reflects a behavioural preoccupation. The measure demonstrated strong invariance across sex and across Grades 5, 7, and 9. Both factors displayed good internal consistency (α = .91 and .87, respectively. Sex and grade differences on both scales were investigated and boys in Grade 5 reported higher levels of both mood management and behavioural preoccupation with screens. There were no sex differences on mood management in Grades 7 and 9, but girls reported higher behavioural preoccupation in

    Building on long-term benefits of early intervention (Paper 2 of this Series) and increasing commitment to early childhood development (Paper 1 of this Series), scaled up support for the youngest children is essential to improving health, human capital, and wellbeing across the life course. In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children. Effective and feasible programmes to support early child development are now available.

However, health provides a critical starting point for scaling up, given its reach to pregnant women, families, and young children. Starting at conception, interventions to promote nurturing care can feasibly build on existing health and nutrition services at limited additional cost. Failure to scale up has severe personal and social consequences. Children at elevated risk for compromised development due to stunting and poverty are likely to forgo about a quarter of average adult income per year, and the cost of inaction to gross domestic product can be double what some countries currently spend on health.

    Appropriate communication skills are essential for understanding patient needs, particularly those of patients with dementia. Assessing health care providers' competence in communicating with patients with dementia is critical for planning a communication education program. However, no formally established scale can be used. The purpose of the current study was to develop a valid and reliable instrument for determining the communication competence of health care providers with patients with dementia. Through use of a literature review and previous clinical experience, an initial 28-item scale was developed to assess the frequency of use of each item by health care providers. Fourteen items were extracted and three factors were distinguished. Results indicated that the internal consistency reliability of the 14-item scale was 0.84. Favorable convergent and discriminant validities were reached. The communication competence scale provides administrators or educators with a useful tool for assessing communication competence of health care providers when interacting with patients with dementia so a suitable education program can be planned and implemented.

  9. The development of small-scale convection below evolving oceanic plates

    Seafloor of older ages shows a constancy of heat flow, and bathymetry that is different from what is expected for a half-space cooling model. These observations led to consideration of the existence of small-scale convection below the lithosphere (Parsons and McKenzie, 1978). Previous studies have characterized the detailed physics of such processes (Davaille and Jaupart, 1994; Choblet and Sotin, 2000; Solomatov and Moresi, 2000; Korenaga and Jordan, 2003 among others). However, questions remain for applications to the Earth: what is the shape of developed small-scale convection, what length-scales are involved, how does associated small-scale convection depend on the plate layout and its time-dependence. Using 3D spherical models of mantle convection with plate-like behaviour (Tackley, 2008), we will present a study of developed small-scale convection in a context of self-organization of plates and mantle flow. Small-scale convection depends on the resistance of the lithosphere, and its development beneath large plates produce network shapes with specific length-scales and orientations (see figure). We will show the impact of the size of plates and the evolution of subduction on the small-scale convection, and characterize how the age-heat flow relationship can change with time. The potential for seismic detection of the spatiotemporal patterns of temperature heterogeneity will also be discussed. ReferencesChoblet, G., and C. Sotin, Phys. Earth Planet.

    Scales to measure perceived control of tablet-treated diabetes were adapted from a measure designed previously for insulin users. Development of the new scale is described and the psychometric properties are examined with responses from 187 tablet-treated patients. The scales consist of seven subscales which may be combined to provide three composite scores indicating the extent to which respondents perceive Personal Control, Medical Control, and Situational Control over their diabetes. Relationships between subscales and composite scores were similar to those found previously for insulin users. Patients were significantly more likely (p less than 0.001) to make attributions to Personal Control for their diabetes management rather than to Medical or Situational Control. As before, predictable biases were found in attributions to positive and negative outcomes. Correlations with medical and other psychological variables indicated that, as expected, stronger perceptions of Personal Control were associated with lower HbA1 levels (r = -0.14; p less than 0.05), lower percent ideal body weight (r = -0.24; p less than 0.01), less Anxiety (r = -0.15; p less than 0.05), greater Positive Well-being (r = 0.21; p less than 0.01) and greater Satisfaction with treatment (r = 0.34; p less than 0.001). Complementary relationships were found with the measure of Situational Control. Wallston and Wallston's speculative Locus of Control typology was investigated using the new measures, and the findings provided support for the value of this approach.

    The goal of the present research was to develop and test a novel conceptual model and corresponding measure of state mindfulness-the State Mindfulness Scale (SMS). We developed the SMS to reflect traditional Buddhist and contemporary psychological science models of mindfulness not similarly reflected in extant published measures of the construct. Study 1 exploratory and confirmatory factor analyses supported a higher order 2-factor solution encompassing 1 second-order state mindfulness factor, and 2 first-order factors, one reflecting state mindfulness of bodily sensations and the other state mindfulness of mental events. Study 2 provided cross-sectional evidence of the convergent, discriminant, and incremental convergent validity of SMS scores with respect to other measures of state and trait mindfulness. Study 3, a randomized control experimental mindfulness intervention study, yielded a number of key findings with respect to SMS stability as a function of time and context, construct validity, incremental sensitivity to change in state mindfulness over time, and incremental predictive criterion-related validity. Findings are discussed with respect to the potential contribution of the SMS to the study of mindfulness as a statelike mental behavior, biopsychobehavioral research on the mechanisms of mindfulness, and clinical evaluation of mindfulness.

    Parent-child feeding interactions during the first two years of life are thought to shape child appetite and obesity risk, but remain poorly studied. This research was designed to develop and assess the Responsiveness to Child Feeding Cues Scale (RCFCS), an observational measure of caregiver responsiveness to child feeding cues relevant to obesity. General responsiveness during feeding as well as maternal responsiveness to child hunger and fullness were rated during mid-morning feeding occasions by 3 trained coders using digitally-recordings. Initial inter-rater reliability and criterion validity were evaluated in a sample of 144 ethnically-diverse mothers of healthy 7- to 24-month-old children. Maternal self-report of demographics and measurements of maternal/child anthropometrics were obtained. Inter-rater agreement for most variables was excellent (ICC>0.80). Mothers tended to be more responsive to child hunger than fullness cues (pchild age, and aspects of feeding, including breastfeeding duration, and self-feeding. The RCFCS is a reliable observational measure of responsive feeding for children <2 years of age that is relevant to obesity in early development. PMID:23419965

    Like other self-conscious emotions, shame takes on particular significance during late childhood and adolescence because of a developing capacity for self-reflection, self-other comparisons, and sensitivity to the views of others. Shame is a potentially important variable in adolescent well-being given its established associations with depression, reduced feelings of self-worth, and problematic anger. Three studies are reported that describe the development and validation of the Adolescent Shame-Proneness Scale (ASPS), a novel semi-idiographic measure of shame-proneness. The ASPS is a 19-item measure assessing 3 components of shame-proneness-negative self-evaluation, externalization, and emotional discomfort. Taken together, the studies support the reliability and validity of the ASPS as a semi-idiographic measure of shame-proneness in adolescents aged 11 to 18 years. ASPS scores correlate as expected with scores on existing measure of shame-proneness and with measures of anger, negative affect, and self-esteem. More important, the data suggest that ASPS scores are related to, but distinct from, guilt. Confirmatory factor analysis supported the validity of the ASPS factor structure (RMSEA = .08, SRMR = .05, CFI = .97, NNFI = .97). The ASPS represents a unique contribution to existing options for measuring shame-proneness in research and clinical contexts. Further work is required to assess the ASPS' temporal stability and its viability and psychometric properties in more culturally diverse samples.

    The field of optometry has become increasingly interested in patient-reported outcomes, reflecting a common trend occurring across the spectrum of healthcare. This article reviews the development of the Contact Lens User Experience: CLUE system designed to assess patient evaluations of contact lenses. CLUE was built using modern psychometric methods such as factor analysis and item response theory. The qualitative process through which relevant domains were identified is outlined as well as the process of creating initial item banks. Psychometric analyses were conducted on the initial item banks and refinements were made to the domains and items. Following this data-driven refinement phase, a second round of data was collected to further refine the items and obtain final item response theory item parameters estimates. Extensive qualitative work identified three key areas patients consider important when describing their experience with contact lenses. Based on item content and psychometric dimensionality assessments, the developing CLUE instruments were ultimately focused around four domains: comfort, vision, handling, and packaging. Item response theory parameters were estimated for the CLUE item banks (377 items), and the resulting scales were found to provide precise and reliable assignment of scores detailing users' subjective experiences with contact lenses. The CLUE family of instruments, as it currently exists, exhibits excellent psychometric properties.

    Research suggests that employee status, and various status proxies, relate to a number of meaningful outcomes in the workplace. The advancement of the study of status in organizational settings has, however, been stymied by the lack of a validated workplace status measure. The purpose of this manuscript, therefore, is to develop and validate a measure of workplace status based on a theoretically grounded definition of status in organizations. Subject-matter experts were used to examine the content validity of the measure. Then, 2 separate samples were employed to assess the psychometric properties (i.e., factor structure, reliability, convergent and discriminant validity) and nomological network of a 5-item, self-report Workplace Status Scale (WSS). To allow for methodological flexibility, an additional 3 samples were used to extend the WSS to coworker reports of a focal employee's status, provide additional evidence for the validity and reliability of the WSS, and to demonstrate consensus among coworker ratings. Together, these studies provide evidence of the psychometric soundness of the WSS for assessing employee status using either self-reports or other-source reports. The implications of the development of the WSS for the study of status in organizations are discussed, and suggestions for future research using the new measure are offered.

    Genome-scale metabolic models often lack annotations that would allow them to be used for further analysis. Previous efforts have focused on associating metabolites in the model with a cross reference, but this can be problematic if the reference is not freely available, multiple resources are used or the metabolite is added from a literature review. Associating each metabolite with chemical structure provides unambiguous identification of the components and a more detailed view of the metabolism. We have developed an open-source desktop application that simplifies the process of adding database cross references and chemical structures to genome-scale metabolic models. Annotated models can be exported to the Systems Biology Markup Language open interchange format. Source code, binaries, documentation and tutorials are freely available at http://johnmay.github.com/metingear. The application is implemented in Java with bundles available for MS Windows and Macintosh OS X.

    Existing self-report questionnaires for the assessment of emotional eating do not differentiate between specific types of emotions and between increased or decreased food intake in response to these emotions. Therefore, we developed a new measure of emotional eating-the Salzburg Emotional Eating Scale (SEES)-for which higher scores indicate eating more than usual in response to emotions and lower scores indicate eating less than usual in response to emotions. In study 1, a pool of items describing 40 emotional states was used. Factor analysis yielded four factors, which represented both positive ( happiness subscale) and negative emotions ( sadness, anger , and anxiety subscales). Subsequently, the scale was reduced to 20 items (5 items for each subscale) and its four-factor structure was replicated in studies 2 and 3. In all three studies, internal consistencies of each subscale were α > 0.70 and mean subscale scores significantly differed from each other such that individuals reported the strongest tendency to eat more than usual when being sad and the strongest tendency to eat less than usual when being anxious (sadness > happiness > anger > anxiety). Higher scores on the happiness subscale related to lower scores on the negative emotions subscales, lower body mass index (BMI), and lower eating pathology. In contrast, higher scores on the negative emotions subscales related to lower scores on the happiness subscale, higher BMI, and higher eating pathology. The SEES represents a useful measure for the investigation of emotional eating by increasing both specificity (differentiation between specific emotional states) and breadth (differentiation between increase and decrease of food intake) in the assessment of the emotion-eating relationship.

    Full Text Available BACKGROUND: Medication adherence is critical in Tuberculosis (TB treatment success, but existing tools are inadequate in identifying non-adherents, reasons for non-adherence or interventions to improve adherence. This study intended to fill the gap by developing and validating a TB medication adherence scale (TBMAS. METHODS: An initial 41-item TBMAS was designed through review of literature, consultation from an 8-member clinical expert panel and a 15-patient focus group, and pilot-testing in 25 TB patients. The questionnaire was validated in 438 patients who visited 23 community health centers for TB treatment in Wuhan from September 1, 2010, to August 31, 2011, using pharmacy refill records in a 15-week period as external criteria for medication adherence. After removing redundant and cross-loading items, the internal consistency, reliability and validity of TBMAS in identifying non-adherents were examined. RESULTS: The final TBMAS included 30 items scored on a 5-point Likert scale, and these items were loaded in nine distinct factors that explained 65% of cumulative variance among respondents. Cronbach's alpha, test-retest reliability and split-half reliability were 0.87, 0.83, and 0.85, respectively. Convergent validity was supported by statistically significant associations between TBMAS scores and adherence measured by pharmacy refill records. Receiver Operating Characteristics curve analysis suggested a cut-off point at 113, with which TBMAS showed a positive predictive value of 65.5% and sensitivity of 82.9% in identifying non-adherents. CONCLUSION: TBMAS demonstrated satisfactory internal consistency, reliability and validity in identifying TB patients with poor adherence and potential causes for non-adherence.

Receiver Operating Characteristics curve analysis suggested a cut-off point at 113, with which TBMAS showed a positive predictive value of 65.5% and sensitivity of 82.9% in identifying non-adherents. TBMAS demonstrated satisfactory internal consistency, reliability and validity in identifying TB patients with poor adherence and potential causes for non-adherence.

    Leading models of sexual dysfunction, such as those proposed by Masters and Johnson (1970), Barlow (1986), and Janssen, Everaerd, Spiering, and Janssen (2000), emphasize the role of anxiety and self-monitoring in the development and persistence of sexual difficulties. These models have considerable explanatory power, but focus on the intrapersonal factors that yield anxiety and self-monitoring. Accounting for the interpersonal context in which sexual activity occurs is also likely to be important. For example, anxiety and self-monitoring may arise from negative, yet accurate, predictions about how one's partner will respond to one's own sexual functioning difficulties. The current studies describe the development and validation of the Response to Sexual Difficulties Scale (RSDS), which was designed to assess how one expects one's partner to respond to one's own sexual difficulties (RSDS-Own Difficulties) and how one expects oneself to respond to one's partner's sexual difficulties (RSDS-Partner Difficulties). Study 1 established the initial reliability and construct validity of the RSDS-Own Difficulties in a sample of adults in committed relationships (N = 59). Study 2 further examined the construct and discriminant validity of the RSDS Own Difficulties and Partner Difficulties in a sample of heterosexual couples (N = 87). Results indicated that both measures had strong internal consistency and were not redundant with measures of mood or personality. Scores on the RSDS-Own Difficulties and Partner Difficulties were strongly associated, indicating that reports of one's own response to one's partner's difficulty matched the partner's assessment of the reaction. RSDS scores predicted sexual functioning, relationship satisfaction, sexual satisfaction, and sexual communication. The RSDS may, then, provide a useful means of assessing the role of interpersonal factors in the development and persistence of sexual difficulties.

    This paper reports the development of a global assessment of functioning (GAF), modified from the DSM Axis V GAF for the prison environment. Focus groups, which were conducted with 36 correctional officers and clinicians in two prisons, provided descriptions of behavior in prison settings to re-align the GAF scale. Face validity was established. It was found that Habitation/Behavior, Social, and Symptoms emerged as important domains of functioning in prison. Gender differences were noted with regard to cleanliness, relationships and coping strategies. The cut-off score was identified at a score where offenders were unable to participate in a disciplinary process due to their mental illness. The structure of prison alters human functioning, requiring different assessment language and ratings to measure perceived behavioral norms and/or expectations. Front-line staff need the ability to observe and communicate behavioral changes quickly and accurately in a prison environment without undue burden upon their workload. This assessment was modified by front-line staff specifically for the prison environment to document quick and frequent assessments of observed changes over time in the offender population.

  4. Development of Full-Scale Ultrathin Shell Reflector

    Full Text Available It is aimed that a new ultrathin shell composite reflector is developed considering different design options to optimize the stiffness/mass ratio, cost, and manufacturing. The reflector is an offset parabolic reflector with a diameter of 6 m, a focal length of 4.8 m, and an offset of 0.3 m and has the ability of folding and self-deploying. For Ku-band missions a full-scale offset parabolic reflector antenna is designed by considering different concepts of stiffening: (i reflective surface and skirt, (ii reflective surface and radial ribs, and (iii reflective surface, skirt, and radial ribs. In a preliminary study, the options are modeled using ABAQUS finite element program and compared with respect to their mass, fundamental frequency, and thermal surface errors. It is found that the option of reflective surface and skirt is more advantageous. The option is further analyzed to optimize the stiffness/mass ratio considering the design parameters of material thickness, width of the skirt, and ply angles. Using the TOPSIS method is determined the best reflector concept among thirty different designs. Accordingly, new design can be said to have some advantages in terms of mass, natural frequency, number of parts, production, and assembly than both SSBR and AstroMesh reflectors.

    The Cross-Cultural Loss Scale (CCLS), a measure of loss associated with crossing national boundaries, was developed across 2 samples of international students. With Sample 1 (N = 262), exploratory factor analyses were used to select the 14 CCLS items and to determine 3 factors: Belonging-Competency (α = .87), National Privileges (α = .68), and Access to Home Familiarity (α = .72). With Sample 2, confirmatory factor analyses (N = 256) cross-validated the 3-factor oblique model as well as a bifactor model. Cronbach alphas of CCLS subscale scores in Sample 2 ranged from .73 to .87. The validity of the CCLS scores was supported by its associations with related variables in the expected directions. Perceived cross-cultural losses were positively associated with negative affect, migration grief and loss, and discrimination and were negatively associated with life satisfaction, positive affect, general self-efficacy, and social connection with mainstream society. Moreover, the CCLS total and 2 subscale scores added significant incremental variance in predicting subjective well-being over and above related constructs. The results indicated measurement invariance and validity equivalency for the CCLS scores between men and women. The overall results from these 2 samples support CCLS as a psychometrically strong measure. 2015 APA, all rights reserved

    To better understand depression's impact on family functioning from the perspectives of patients with major depressive disorder (MDD) and their partners; to develop and test patient and partner versions of a new self-reported measure, the Depression and Family Functioning Scale (DFFS), for use in clinical trials. Concept elicitation interviews were conducted with 32 adults with clinician-diagnosed moderate-to-severe MDD and their respective partners. Twenty-six items were drafted to address relevant aspects of family functioning and were then tested and refined through two iterative sets of cognitive debriefing interviews, each conducted by the same pair of highly experienced researchers, including a licensed clinical psychologist. Depression negatively affects family functioning through poorer communication, increased conflicts, decreased family interaction, and decreased intimacy. No existing instrument measured all domains of interest, or had been rigorously developed and psychometrically validated in the target populations. The draft DFFS items generally tested well and only minor modifications were made to the items after the second set of interviews. Both patients and partners indicated that the final set of 15 DFFS items addresses all concepts of importance. The DFFS evaluates the impact of depression on family functioning and has the potential to provide important information that can facilitate a more comprehensive evaluation of new treatments in clinical trial settings. Although MDD severity was not confirmed with a standardized interview, in clinical practice in the US, MDD is generally not diagnosed with the use of a structured clinical interview or clinician-administered tool. In the current study, depression severity had little (if any) impact on the specific concepts elicited as being important to family functioning. In fact, patients with milder depression had more insight and were able to better articulate changes in family functioning with

    Over the past 15 years, the geoscience education community has grown substantially and developed broad and deep capacity for collaboration and dissemination of ideas. While this community is best viewed as emergent from complex interactions among changing educational needs and opportunities, we highlight the role of several large projects in the development of a network within this community. In the 1990s, three NSF projects came together to build a robust web infrastructure to support the production and dissemination of on-line resources: On The Cutting Edge (OTCE), Earth Exploration Toolbook, and Starting Point: Teaching Introductory Geoscience. Along with the contemporaneous Digital Library for Earth System Education, these projects engaged geoscience educators nationwide in exploring professional development experiences that produced lasting on-line resources, collaborative authoring of resources, and models for web-based support for geoscience teaching. As a result, a culture developed in the 2000s in which geoscience educators anticipated that resources for geoscience teaching would be shared broadly and that collaborative authoring would be productive and engaging. By this time, a diverse set of examples demonstrated the power of the web infrastructure in supporting collaboration, dissemination and professional development . Building on this foundation, more recent work has expanded both the size of the network and the scope of its work. Many large research projects initiated collaborations to disseminate resources supporting educational use of their data. Research results from the rapidly expanding geoscience education research community were integrated into the Pedagogies in Action website and OTCE. Projects engaged faculty across the nation in large-scale data collection and educational research. The Climate Literacy and Energy Awareness Network and OTCE engaged community members in reviewing the expanding body of on-line resources. Building Strong

    Because organizational culture is increasingly understood as fundamental to achieving high performance in hospital and other healthcare settings, the ability to measure this nuanced concept empirically has gained importance. Aside from measures of patient safety culture, no measure of organizational culture has been widely endorsed in the medical literature, limiting replication of previous findings and broader use in interventional studies. We sought to develop and assess the validity and reliability of a scale for assessing organizational culture in the context of hospitals' efforts to reducing 30-day risk-standardized mortality after acute myocardial infarction. The 31-item scale was completed by 147 individuals representing 10 hospitals during August and September 2014. The resulting organizational culture scale demonstrated high level of construct validity and internal consistency. Factor analyses indicated that the 31 items loaded well (loading values 0.48-0.90), supporting distinguishable domains of (1) learning environment, (2) psychological safety, (3) commitment to the organization, (4) senior management support, and (5) time for improvement efforts. Cronbach α coefficients were 0.94 for the scale and ranged from 0.77 to 0.88 for the subscales. The scale displayed reasonable convergent validity and statistically significant variability across hospitals, with hospital identity accounting for 11.3% of variance in culture scores across respondents. We developed and validated a relatively easy-to-administer survey that was able to detect substantial variability in organizational culture across different hospitals and may be useful in measuring hospital culture and evaluating changes in culture over time as part performance improvement efforts. © 2017 American Heart Association, Inc.

    Illness-related stigma has attracted considerable research interest, but few studies have specifically examined stigmatisation of cancer in the non-patient population. The present study developed and validated a Cancer Stigma Scale (CASS) for use in the general population. An item pool was developed on the basis of previous research into illness-related stigma in the general population and patients with cancer. Two studies were carried out. The first study used Exploratory factor analysis to explore the structure of items in a sample of 462 postgraduate students recruited through a London university. The second study used Confirmatory factor analysis to confirm the structure among 238 adults recruited through an online market research panel. Internal reliability, test-retest reliability and construct validity were also assessed. Exploratory factor analysis suggested six subscales, representing: Awkwardness, Severity, Avoidance, Policy Opposition, Personal Responsibility and Financial Discrimination. Confirmatory factor analysis confirmed this structure with a 25-item scale. All subscales showed adequate to good internal and test-retest reliability in both samples. Construct validity was also good, with mean scores for each subscale varying in the expected directions by age, gender, experience of cancer, awareness of lifestyle risk factors for cancer, and social desirability. Means for the subscales were consistent across the two samples. These findings highlight the complexity of cancer stigma and provide the Cancer Stigma Scale (CASS) which can be used to compare populations, types of cancer and evaluate the effects of interventions designed to reduce cancer stigma in non-patient populations.

    Alcohol consumption has been suggested to be associated with a dysregulation in habit formation and execution in dependent patients. Although there are established craving questionnaires assessing various components of craving, to our knowledge, no questionnaire exists to assess habitual and automated substance intake. In this study, we present and validate the "Craving Automated Scale for Alcohol" (CAS-A), a newly developed questionnaire assessing craving and other components of automated addictive behavior. Forty-three recently detoxified alcohol-dependent patients were examined in an inpatient setting using a cross-sectional design. The CAS-A, a self-report questionnaire, was applied. According to classical test theory, we conducted principal component analyses (PCAs) to identify the components of CAS-A, after which we validated it using established craving questionnaires. Thirty-two healthy participants served as a control group. Our first-order PCA identified a 5-factor solution. A second-order analysis then identified 2 general factors. These factors were partially associated with established craving measures and with the severity of dependence. Our findings suggest that CAS-A assesses additional components of addictive behavior compared to established measures. We interpret the 5 CAS-A factors as "only aware in hindsight," "no deliberate decision," "contrary to intention," "no perception," and "no control." We suggest the 2 general factors be interpreted as "unaware" and "nonvolitional." Our results indicate that the CAS-A indeed assesses some components of automated craving and automated drinking behavior in a more sophisticated way than established questionnaires. The CAS-A as a retrospective questionnaire can be considered to be a trait rather than a state measure. Copyright © 2015 by the Research Society on Alcoholism.

    The objective of this article was to describe 1) the validation of 2 similar but not identical food security modules used to collect data from 2 vulnerable populations, southern Lebanon residents (n = 815) and Palestinian refugees in Lebanon (n = 2501), and 2) the development and validation of an Arab Family Food Security Scale (AFFSS). The surveys used a cluster-randomized sampling design. The 2 food security subscales underwent face and construct validity. In addition, both of these tools and the AFFSS underwent psychometric assessment for internal validity by using statistical methods based on Item Response Theory. The food security questions tested by focus groups were understood and accepted in all regions of Lebanon. The food security subscales and the AFFSS had acceptable levels of internal consistency. The psychometric assessment confirmed that the 7 items of the AFFSS had good internal validity and reasonable reliability with item in-fits from 0.73 to 1.16. Food insecurity was identified among 42% of southern Lebanese and 62% of Palestinian refugee households. The determinants and consequences of food security measured in this study provide additional support for the validity of the modules. Using multivariate logistic regression, the higher the mean monthly income per household member and the higher the educational attainment of the head of household, the lower the risk of food insecurity [ORs (95% CIs): 0.99 (0.98, 0.99) and 0.66 (0.54, 0.80), respectively]. There was a strong significant association between food insecurity and lower food expenditure and lower intake of all food categories except for legumes, which was significantly associated in the opposite direction (P < 0.001). The odds of borrowing money and accepting gifts/donations were significantly higher among moderately and severely food-insecure households (P < 0.000). The AFFSS has been validated within Lebanon and can potentially be extended to other Arab-speaking populations.

    A chemically defined media was developed for growing Agrobacterium tumefaciens at large scale for commercial production of recombinant proteins by transient expression in plants. Design of experiments was used to identify major and secondary effects of ten media components: sucrose, ammonium sulfate ((NH 4 ) 2 SO 4 ), magnesium sulfate heptahydrate (MgSO 4 *7H 2 O), calcium chloride dihydrate (CaCl 2 *2H 2 O), iron (II) sulfate heptahydrate (FeSO 4 *7H 2 O), manganese (II) sulfate monohydrate (MnSO 4 *H 2 O), zinc sulfate heptahydrate (ZnSO 4 *7H 2 O), sodium chloride (NaCl), potassium chloride (KCl) and a sodium/potassium phosphate buffer (Na 2 HPO 4 /KH 2 PO 4 ). Calcium and zinc were found to have no detectable impact on biomass concentration or transient expression level, and concentrations of the other components that maximized final biomass concentration were determined. The maximum specific growth rate of Agrobacterium strain C58C1 pTFS40 in this media was 0.33 ± 0.01 h -1 and the final biomass concentration after 26 h of batch growth in shake flasks was 2.6 g dry cell weight/L. Transient expression levels of the reporter protein GUS following infiltration of a recombinant Agrobacterium strain C58C1 into N. benthamiana were comparable when the strain was grown in the defined media, Lysogeny Broth (LB) media, or yeast extract-peptone (YEP) media. In LB and YEP media, free amino acid concentration was measured at three points over the course of batch growth of Agrobacterium strain C58C1 pTFS40; results indicated that l-serine and l-asparagine were depleted from the media first, followed by l-alanine and l-glutamic acid. © 2017 American Institute of Chemical Engineers Biotechnol.

    2017-11-01

    Gene co-expression network analysis has been a research method widely used in systematically exploring gene function and interaction. Using the Weighted Gene Co-expression Network Analysis (WGCNA) approach to construct a gene co-expression network using data from a customized 44K microarray transcriptome of chicken epidermal embryogenesis, we have identified two distinct modules that are highly correlated with scale or feather development traits. Signaling pathways related to feather development were enriched in the traditional KEGG pathway analysis and functional terms relating specifically to embryonic epidermal development were also enriched in the Gene Ontology analysis. Significant enrichment annotations were discovered from customized enrichment tools such as Modular Single-Set Enrichment Test (MSET) and Medical Subject Headings (MeSH). Hub genes in both trait-correlated modules showed strong specific functional enrichment toward epidermal development. Also, regulatory elements, such as transcription factors and miRNAs, were targeted in the significant enrichment result. This work highlights the advantage of this methodology for functional prediction of genes not previously associated with scale- and feather trait-related modules.

    Krumrei-Mancuso, Elizabeth J; Rouse, Steven V

    2016-01-01

    A series of studies was conducted to create the 22-item Comprehensive Intellectual Humility Scale on the basis of theoretical descriptions of intellectual humility, expert reviews, pilot studies, and exploratory and confirmatory factor analyses. The scale measures 4 distinct but intercorrelated aspects of intellectual humility, including independence of intellect and ego, openness to revising one's viewpoint, respect for others' viewpoints, and lack of intellectual overconfidence. Internal consistency and test-retest analyses provided reliable scale and subscale scores within numerous independent samples. Validation data were obtained from multiple, independent samples, supporting appropriate levels of convergent, discriminant, and predictive validity. The analyses suggest that the scale has utility as a self-report measure for future research.

    Terrorism creates lingering anxiety about future attacks. In prior terror research, the conceptualization and measurement of coping behaviors were constrained by the use of existing coping scales that index reactions to daily hassles and demands. The authors created and validated the Coping with Terror Scale to fill the measurement gap. The authors emphasized content validity, leveraging the knowledge of terror experts and groups of Israelis. A multistep approach involved construct definition and item generation, trimming and refining the measure, exploring the factor structure underlying item responses, and garnering evidence for reliability and validity. The final scale comprised six factors that were generally consistent with the authors' original construct specifications. Scores on items linked to these factors demonstrate good reliability and validity. Future studies using the Coping with Terror Scale with other populations facing terrorist threats are needed to test its ability to predict resilience, functional impairment, and psychological distress.

    Full Text Available This study employed qualitative construct mapping and factor analysis to construct a scale to measure attitudes toward dementia. Five family caregivers, five professionals, and five college students participated in structured interviews. Qualitative analysis of the interviews led to a 46-item scale, which was reduced to 20 items following principal axis factoring with two different samples: college students (=302 and certified nursing assistant students (=145. Confirmatory factor analysis was then conducted with another sample of college students (=157. The final scale, titled the Dementia Attitudes Scale (DAS, essentially had a two-factor structure; the factors were labeled “dementia knowledge” and “social comfort.” Total-scale Cronbach's alphas ranged 0.83–0.85. Evidence for convergent validity was promising, as the DAS correlated significantly with scales that measured ageism and attitudes toward disabilities (range of correlations = 0.44–0.55; mean correlation =0.50. These findings demonstrate the reliability and validity of the DAS, supporting its use as a research tool.

    Patients with COPD often experience restriction in their activities of daily living (ADL) due to dyspnea. This type of restriction is unique to patients with COPD and cannot be adequately evaluated by the generic ADL scales. This study developed an ADL scale (the Activity of Daily Living Dyspnea scale [ADL-D scale]) for patients with COPD and investigated its validity and internal consistency. Patients with stable COPD were recruited and completed a pilot 26-item questionnaire. Patients also performed the Incremental Shuttle Walk Test (ISWT), and completed the St George's Respiratory Questionnaire (SGRQ), and Medical Research Council (MRC) dyspnea grade. There were 83 male participants who completed the pilot questionnaire. Following the pilot, 8 items that were not undertaken by the majority of subjects, and 3 items judged to be of low clinical importance by physical therapists were removed from the pilot questionnaire. The final ADL-D scale contained 15 items. Scores obtained with the ADL-D scale were significantly correlated with the MRC dyspnea grades, distance walked on the ISWT and SGRQ scores. The ADL-D scores were significantly different across the five grades of the MRC dyspnea grade. The ADL-D scale showed high consistency (Chronbach's alpha coefficient of 0.96). The ADL-D scale is a useful scale for assessing impairments in ADL in Japanese male patients with COPD.

A prototype self-rating smartphone-dependence scale was tested on 133 medical students who use smartphones more frequently than other devices to access web pages. Each response was scored on a Likert scale (0, 1, 2, 3), with higher scores indicating greater dependence. To select items for the final scale, exploratory factor analysis was conducted. On the basis of factor analysis results, we designed the Wakayama Smartphone-Dependence Scale (WSDS) comprising 21 items with 3 subscales: immersion in Internet communication; using a smartphone for extended periods of time and neglecting social obligations and other tasks; using a smartphone while doing something else and neglect of etiquette. Our analysis confirmed the validity of the different elements of the WSDS: the reliability coefficient (Cronbach's alpha) values of all subscales and total WSDS were from 0.79 to 0.83 and 0.88, respectively. These findings suggest that the WSDS is a useful tool for rating smartphone dependence.

    The present study reports the development and application of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS), a parental self-report designed to assess the quantity and quality of affordances in the home environment that are conducive to motor development for infants aged 3-18 months. Steps in its development included use of expert feedback, establishment of construct validity, interrater and intrarater reliability, and predictive validity. With all phases of the project, 113 homes were involved. Intraclass correlation coefficients for interrater and intrarater reliability for the total score were 1 and 0.94, respectively. In addition, results indicate that the test has the characteristic of differentiating a wide range of scores. Regression analysis for the AHEMD-IS and motor development using the Alberta Infant Motor Scale supports preliminary evidence for predictive validity. Our findings suggest that the AHEMD-IS has sufficient reliability and validity as an instrument for assessing affordances in the home environment, with clinical and research applications. © 2011 The Authors.

    Lauren C Ng

    Full Text Available This study developed and validated the Youth Conduct Problems Scale-Rwanda (YCPS-R. Qualitative free listing (n = 74 and key informant interviews (n = 47 identified local conduct problems, which were compared to existing standardized conduct problem scales and used to develop the YCPS-R. The YCPS-R was cognitive tested by 12 youth and caregiver participants, and assessed for test-retest and inter-rater reliability in a sample of 64 youth. Finally, a purposive sample of 389 youth and their caregivers were enrolled in a validity study. Validity was assessed by comparing YCPS-R scores to conduct disorder, which was diagnosed with the Mini International Neuropsychiatric Interview for Children, and functional impairment scores on the World Health Organization Disability Assessment Schedule Child Version. ROC analyses assessed the YCPS-R's ability to discriminate between youth with and without conduct disorder. Qualitative data identified a local presentation of youth conduct problems that did not match previously standardized measures. Therefore, the YCPS-R was developed solely from local conduct problems. Cognitive testing indicated that the YCPS-R was understandable and required little modification. The YCPS-R demonstrated good reliability, construct, criterion, and discriminant validity, and fair classification accuracy. The YCPS-R is a locally-derived measure of Rwandan youth conduct problems that demonstrated good psychometric properties and could be used for further research.

  11. Toward developing a scale to empirically measure psychotic defense mechanisms.

    2010-12-01

    In recent years, research on psychological processes has greatly advanced our understanding of various psychopathologies. Defense mechanisms, for example, have been described as observable phenomena, and studies have shown meaningful relationships among these processes and other measurable dimensions of health and illness. Despite some notable exceptions, one area that has been overlooked is the empirical study of defenses in psychotic disorders. This is in part due to the lack of valid instruments measuring psychotic-level defenses. Propadeutic to creating an empirical scale for measuring psychotic defenses, the psychoanalytic and empirical literature on psychotic defenses is reviewed, after which the concept of psychotic defenses as measured by the P-DMRS (Psychotic-Defense Mechanism Rating Scales)--which can be used independently or in combination with the current DMRS (Defense Mechanism Rating Scales)--is operationalized. Finally, current research directions applying the P-DMRS to the clinical setting are presented, as well as its implications for guiding current clinical practice.

    At present rapid progress is being made in the application of soft x-ray lasers to fields such as microscopy and microlithography. A critical factor in the range of suitable applications is the scale and hence cost of the soft x-ray lasers. At Princeton, gain at 183 angstrom has been obtained with relatively low pump laser energies (as low as 6J) in a ''portable'' small-scale soft x-ray laser system. We will also discuss aspects of data interpretation and pitfalls to be avoided in measurements of gain in such systems. 14 refs., 7 figs

    Rees, Charlotte; Sheard, Charlotte; Davies, Susie

    2002-02-01

    There is little research identifying medical students' attitudes towards communication skills learning. This pilot study outlines the development of a new scale to measure attitudes towards communication skills learning. First- and second-year medical students (n = 490) completed the 26-item Communication Skills Attitude Scale (CSAS) and 39 students completed the CSAS on a second occasion. Factor analysis was conducted to determine the factors underpinning the scale. The internal consistency of the subscales was determined using alpha coefficients. The test-retest reliability of the individual scale items were determined using weighted kappa coefficients and the test-retest reliability of the subscales were established using intraclass correlation coefficients. Maximum likelihood extraction with direct oblimin rotation resulted in a 2-factor scale with 13 items on each subscale. Factor I represented positive attitudes towards communication skills learning and factor II represented negative attitudes. Subscale I had an internal consistency of alpha=0.873 and an intraclass correlation of 0.646 (P attitude subscales (n=8, 61.5%) possessed moderate test-retest reliability. The development of a new and reliable scale to identify medical students' attitudes towards communication skills learning will enable researchers to explore the relationships between medical students' attitudes and their demographic and education-related characteristics. Further work is needed to validate this scale among a broader population of medical students.

    In the past decade, there has been growing recognition of the need to involve clients in decisions about the healthcare they receive and in the evaluation of services offered. In health services research, survey and scaling methods have become important tools for research into 'consumer views' and the perspectives of people receiving healthcare. In spite of the increase in recent years in the participation of parents in their children's Speech and Language Therapy (SLT), there has been little attempt to investigate parents' perceptions and opinions of the services they receive. Moreover, there has been no previous attempt to derive a scale to measure these attitudes. The paper reports a study that explored the attitudes to therapy of 81 parents whose preschool children were receiving SLT intervention. Factor analysis of 12 items on a questionnaire revealed three issues salient in parental attitudes to therapy: practical help, emotional support and the perceived effectiveness of the service. The validity of these factors was supported by other findings from the questionnaire. The properties of the resulting scales are discussed and the ways in which they might be further refined and developed for use in SLT are suggested.

    2015-06-01

    Full Text Available Traffic accidents cause one of the highest numbers of severe injuries in the whole population spectrum. The numbers of deaths and seriously injured citizens prove that traffic accidents and their consequences are still a serious problem to be solved. The paper contributes to the field of vehicle safety technology with a virtual approach. Exploitation of the previously developed scaling algorithm enables the creation of a specific anthropometric model based on a validated reference model. The aim of the paper is to prove the biofidelity of the small percentile six years old virtual human model developed by automatic down-scaling in a frontal impact. For the automatically developed six years old virtual specific anthropometric model, the Kroell impact test is simulated and the results are compared to the experimental data. The chosen approach shows good correspondence of the scaled model performance to the experimental corridors.

    Scaling in the context of REACH means: use of simple mathematics to check, whether chemi-cals are used in a safe way. Even in case if certain conditions of use deviate from the exposure scenario. In specific cases, scaling offers downstream users the opportunity to demonstrate coverage by an exposure scenario for their individual conditions of use. In this report we describe the duty of downstream users to check their conditions of use. We give a definition of scaling related to REACH. We describe objectives and results of scaling. We characterise available scaling tools in a structured way. We describe options for further development and harmonisation of scaling tools. Under use of the experience with existing tools, we develop a guidance document on scaling. Three examples in this guidance make clear how scaling works. In five steps. The guidance is addressed to persons using substances in industrial or professional applications - downstream users according to REACH. In addition, the guidance supports producers of substances and formulators who want to develop scaling tools for their customers. The report includes a calculation table for scaling related to the environment (REACH Scale Environment). In addition, it includes a template to generate product-specific scaling tools. This report focuses on scaling related to environmental exposure assessment. Scaling is possible related to workers and consumer exposure, too. References for this are given in chapter 7. (orig.)

    The Cosmology Large Angular Scale Surveyor (CLASS) will measure the polarization of the Cosmic Microwave Background to search for and characterize the polarized signature of inflation. CLASS will operate from the Atacama Desert and observe ˜ 70 % of the sky. A variable-delay polarization modulator provides modulation of the polarization at ˜ 10 Hz to suppress the 1/ f noise of the atmosphere and enable the measurement of the large angular scale polarization modes. The measurement of the inflationary signal across angular scales that spans both the recombination and reionization features allows a test of the predicted shape of the polarized angular power spectra in addition to a measurement of the energy scale of inflation. CLASS is an array of telescopes covering frequencies of 38, 93, 148, and 217 GHz. These frequencies straddle the foreground minimum and thus allow the extraction of foregrounds from the primordial signal. Each focal plane contains feedhorn-coupled transition-edge sensors that simultaneously detect two orthogonal linear polarizations. The use of single-crystal silicon as the dielectric for the on-chip transmission lines enables both high efficiency and uniformity in fabrication. Integrated band definition has been implemented that both controls the bandpass of the single-mode transmission on the chip and prevents stray light from coupling to the detectors.

    2017-11-01

    Clinicians commonly fail to use cognitive behavioural therapy (CBT) adequately, but the reasons for such omissions are not well understood. The objective of this study was to create and validate a measure to assess clinicians' attitudes towards CBT - the Negative Attitudes towards CBT Scale (NACS). The participants were 204 clinicians from various mental healthcare fields. Each completed the NACS, measures of anxiety and self-esteem, and a measure of therapists' use of CBT and non-CBT techniques and their confidence in using those techniques. Exploratory factor analysis was used to determine the factor structure of the NACS, and scale internal consistency was tested. A single, 16-item scale emerged from the factor analysis of the NACS, and that scale had good internal consistency. Clinicians' negative attitudes and their anxiety had different patterns of association with the use of CBT and other therapeutic techniques. The findings suggest that clinicians' attitudes and emotions each need to be considered when understanding why many clinicians fail to deliver the optimum version of evidence-based CBT. They also suggest that training effective CBT clinicians might depend on understanding and targeting such internal states.

    Characteristics of the human-animal bond can be influenced by both owner-related and pet-related factors, which likely differ between species. Three studies adapted the Monash Dog-Owner Relationship Scale (MDORS) to permit assessment of human-cat interactions as perceived by the cat's owner. In Study 1293 female cat owners completed a modified version of the MDORS, where 'dog' was replaced with 'cat' for all items. Responses were compared with a matched sample of female dog owners. A partial least squares discriminant analysis revealed systematic differences between cat and dog owners in the Dog (Cat)-Owner Interaction subscale (MDORS subscale 1), but not for Perceived Emotional Closeness or Perceived Costs (Subscales 2 and 3). Study 2 involved analysis of free-text descriptions of cat-owner interactions provided by 61 female cat owners. Text mining identified key words which were used to create additional questions for a new Cat-Owner Interaction subscale. In Study 3, the resulting cat-owner relationship scale (CORS) was tested in a group of 570 cat owners. The main psychometric properties of the scale, including internal consistency and factor structure, were evaluated. We propose that this scale can be used to accurately assess owner perceptions of their relationship with their cat. A modified scale, combining items from the CORS and MDORS (a C/DORS), is also provided for when researchers would find it desirable to compare human-cat and human-dog interactions.

    As the oil and gas industry strives to replace ageing, environmentally undesirable scale inhibitors there is an ever increasing use of polymeric inhibitors. The incorporation of phosphorous functionality into a polymer backbone has been shown to improve inhibition efficiency, enhance adsorption characteristics and allow the polymer concentration to be analyzed by elemental phosphorus. It is known that some phosphorus tagged polymers can be problematic to analyze in oil field brines as they typically have a low phosphorus content which is difficult to determine from the background. The development of novel phosphorus functionalized polymeric scale inhibitors was previously described (IBP3530-10). This paper follows the development of the inhibitor class. Utilizing extensive laboratory testing the interactive nature of the scale inhibitors and reservoir lithology was studied. These novel phosphorus functionalized inhibitors were compared to a number of other available scale inhibitors. The incorporation of phosphorus functionality into polymeric inhibitors can be expensive utilizing traditional methods as the phosphorus containing monomers are the financially limiting factor. These are typically vinyl phosphonic acid (VPA), or vinyl diphosphonic acid (VDPA). The novel phosphorus functionalized monomers utilized herein are simpler to manufacture allowing higher phosphorus content within the polymer backbone. The addition of phosphorus into a polymer backbone has previously been known to exacerbate analysis issues in some commercially available scale inhibitors. This is due to incomplete polymerization reactions leaving free and/or inorganic phosphorus containing moieties which can interfere with the analysis, or low levels of phosphorus within end-capped polymers can make it difficult to determine the active concentration accurately within field brines which contain many impuritie. Polymeric inhibitors are known to contain a range of molecular weights with varying

    Full Text Available The aim of this paper is to develop a reliable and valid e-learning quality measurement scales from the learner as well as faculty perspectives in Indian context. Exploratory factor analysis followed by confirmatory factor analysis was done which is presented in two forms; covariance model and the structural model. The covariance model shows that the factors namely collaboration, industry acceptance and value addition are important from the learner’s point of view whereas the factors namely transparency in assessment, technical know-how and engagement (from students are important from faculty point of view. Factors namely course content and design structures (technology/website design are found equally important for learner’s as well as faculty’s perspective. The structural models validate the previously extracted factors along with their indicators. The findings of this study validate the long held belief that e-learning quality is a multidimensional construct and serves as a critical success factor. The proposed scale will help in identifying issues that contribute towards e-learning quality in Indian context and thereby formulating strategies accordingly, resulting in efficient (in terms of cost and effective (outcomes e-learning practices, which is the necessity of the hour for the economic development of the country. A fair amount of literature on e-learning dealt with identifying factors explaining the constructs of quality, perceived value and satisfaction. But there is paucity of research pertaining to e-learning quality scale development and validation from the learner as well as faculty perspective. This study is an attempt to bridge this gap in the existing literature.

    Development of realistic storm scenarios that can be played through the exposed systems is one of the key requirements for carrying out quantitative space weather hazards assessments. In the geomagnetically induced currents (GIC) and power grids context, these scenarios have to quantify the spatiotemporal evolution of the geoelectric field that drives the potentially hazardous currents in the system. In response to the Federal Energy Regulatory Commission (FERC) order 779, a team of scientists and engineers that worked under the auspices of North American Electric Reliability Corporation (NERC), has developed extreme geomagnetic storm and geoelectric field benchmark(s) that use various scaling factors that account for geomagnetic latitude and ground structure of the locations of interest. These benchmarks, together with the information generated in the National Space Weather Action Plan, are the foundation for the hazards assessments that the industry will be carrying out in response to the FERC order and under the auspices of the National Science and Technology Council. While the scaling factors developed in the past work were based on the best available information, there is now significant new information available for parts of the U.S. pertaining to the ground response to external geomagnetic field excitation. The significant new information includes the results magnetotelluric surveys that have been conducted over the past few years across the contiguous US and results from previous surveys that have been made available in a combined online database. In this paper, we distill this new information in the framework of the NERC benchmark and in terms of updated ground response scaling factors thereby allowing straightforward utilization in the hazard assessments. We also outline the path forward for improving the overall extreme event benchmark scenario(s) including generalization of the storm waveforms and geoelectric field spatial patterns.

    Highlights: • New ORIGEN libraries for CANDU 28 and 37-element fuel assemblies have been created. • These new reactor data libraries are based on modern ENDF/B-VII.0 cross-section data. • The updated CANDU data libraries show good agreement with radiochemical assay data. • Eu-154 overestimated when using ENDF-VII.0 due to a lower thermal capture cross-section. - Abstract: A new set of SCALE fuel lattice models have been developed for the 28-element and 37-element CANDU fuel assembly designs using modern cross-section data from ENDF-B/VII.0 in order to produce new reactor data libraries for SCALE/ORIGEN depletion analyses. These new libraries are intended to provide users with a convenient means of evaluating depletion of CANDU fuel assemblies using ORIGEN through pre-generated cross sections based on SCALE lattice physics calculations. The performance of the new CANDU ORIGEN libraries in depletion analysis benchmarks to radiochemical assay data were compared to the previous version of the CANDU libraries provided with SCALE (based on WIMS-AECL models). Benchmark comparisons with available radiochemical assay data indicate that the new cross-section libraries perform well at matching major actinide species (U/Pu), which are generally within 1–4% of experimental values. The library also showed similar or better results over the WIMS-AECL library regarding fission product species and minor actinoids (Np, Am, and Cm). However, a notable exception was in calculated inventories of {sup 154}Eu and {sup 155}Eu, where the new library employing modern nuclear data (ENDF/B-VII.0) performed substantially poorer than the previous WIMS-AECL library (which used ENDF-B/VI.8 cross-sections for these species). The cause for this discrepancy appears to be due to differences in the {sup 154}Eu thermal capture cross-section between ENDF/B-VI.8 and ENDF/B-VII.0, an effect which is exacerbated by the highly thermalized flux of a CANDU heavy water reactor compared to that of a

    Full Text Available Small-scale fisheries (SSFs engage the vast majority of the world’s fishers but are struggling to keep pace with coastal populations, and stocks are declining to levels that threaten reproductive capacity. The provision of food and livelihoods to low-income fishers into the future will be unlikely without radical changes to fisheries policy. We draw on repeating analogies of driving a car to illustrate fundamental reforms needed for driving (managing small-scale fisheries. SSFs will continue to be unsustainable by relying too heavily on output controls (the ‘brake’. Managers need to move away from routinely using moratoria (i.e. the ‘handbrake’ as a management measure, although these measures may be needed as a last resort. Scientists (‘backseat drivers’ must engage more directly with fishery management agencies to understand their constraints and needs. Resource managers must come to terms with regulating fishing inputs (the ‘accelerator’ by imposing limited-entry rules, vessel limitations or short fishing seasons in addition to sensible output controls. Reforms to resource management will need to entail unpopular measures if small-scale fisheries are to deliver sustained benefits to fishing communities into the future.

Background: Establishing an accurate diagnosis is highly dependent upon the quality of the radiographic image. Image quality, as a construct (i.e. set of attributes that makes up the image quality), continues to play an essential role in the field of diagnostic radiography. The process of assessing image quality can be facilitated by using criteria, such as the European Commission (EC) guidelines for quality criteria as published in 1996. However, with the advent of new technology (Computed Radiography and Digital Radiography), some of the EC criteria may no longer be suitable for assessing the visual quality of a digital radiographic image. Moreover, a lack of validated visual image quality scales in the literature can also lead to significant variations in image quality evaluation. Creating and validating visual image quality scales, using a robust methodology, could reduce variability and improve the validity and reliability of perceptual image quality evaluations

    Build up of scale deposits on the walls of geothermal wells can occur rapidly due to the high dissolved solids content of geothermal fluids. Scale formation is a significant problem for both the well and for surface heat transfer equipment. Geothermal brines contain a wide variety if dissolved salts including carbonates, silicates, sulfates, and metal sulfides. One technology recently proposed for scale removal is the use of an ultrasonic device. In the present effort we apply cavitation in a more direct manner by the use of acoustically enhanced cavitating water jets which can be made to be much more efficient and aggressive than ultrasonic devices. Cavitating and self-resonating jet technologies have been proven to enhance the erosive power of liquid jets in a number of cutting, cleaning, and drilling applications. In this study we investigated two related technologies - one that employs cavitation and one that breaks the jet up into a series of slugs that produce water hammer type pressures upon impact. These technologies enable operation in both submerged and nonsubmerged conditions.

    We describe the development and preliminary psychometric testing of the Daily Activities of Infants Scale (DAIS), a parent-completed measure of opportunities parents provide infants for development of postural control and movement. First we obtained 1300 photographs of typical activities from 17 families with infants aged 4 to 11 months. Through consensus we established nine dimensions of activities, graded across three levels of opportunity for development. Pilot testing supported content validity of the DAIS. Subsequently, 50 parents of infants born preterm aged 4 to 11 months participated in psychometric testing. There were 25 male and 25 female infant participants with a mean gestational age of 29.4 weeks (SD 3.6) and a mean birthweight of 1266 grams (SD 635). We found that completion of the DAIS over 1 day was representative of data collected over 3 sequential days. Older infants obtained significantly higher DAIS scores than younger infants, providing preliminary evidence for discriminant validity. The DAIS scores demonstrated a part-correlation of 0.20 (pAlberta Infant Motor Scale obtained concurrently, providing some evidence for convergent validity. The intraclass correlation coefficients reflecting interrater reliability and test-retest reliability of the total DAIS score were 0.76 (95% confidence interval [CI] 0.60-0.86) and 0.77 (95% CI 0.60-0.87) respectively. The DAIS has sufficient reliability and validity for use in clinical practice and research.

    Exosomes are cell-secreted nanovesicles (40-200 nm) that represent a rich source of novel biomarkers in the diagnosis and prognosis of certain diseases. Despite the increasingly recognized relevance of these vesicles as biomarkers, their detection has been limited due in part to current technical challenges in the rapid isolation and analysis of exosomes. The complexity of the development of analytical platforms relies on the heterogeneous composition of the exosome membrane. One of the most attractive tests is the inmunochromatographic strips, which allow rapid detection by unskilled operators. We have successfully developed a novel lateral flow immunoassay (LFIA) for the detection of exosomes based on the use of tetraspanins as targets. We have applied this platform for the detection of exosomes purified from different sources: cell culture supernatants, human plasma and urine. As proof of concept, we explored the analytical potential of this LFIA platform to accurately quantify exosomes purified from a human metastatic melanoma cell line. The one-step assay can be completed in 15 min, with a limit of detection of 8.54×10(5) exosomes/µL when a blend of anti-CD9 and anti-CD81 were selected as capture antibodies and anti-CD63 labelled with gold nanoparticles as detection antibody. Based on our results, this platform could be well suited to be used as a rapid exosome quantification tool, with promising diagnostic applications, bearing in mind that the detection of exosomes from different sources may require adaptation of the analytical settings to their specific composition.

    Women's sexual function may be influenced by various factors including medical conditions, trauma or abuse, medications, relationship dynamics, relaxation, mood, and body image. However, few studies have explored the influence of a woman's genital self-image on her sexual function or behaviors. The purpose of this study was to establish a reliable and valid measure of female genital self-image, the Female Genital Self-Image Scale (FGSIS), and to assess the relationship between scores on the FGSIS and women's sexual function. The FGSIS was developed in two stages. Phase One involved an analysis of cross-sectional paper-based survey data and a review of the literature. Phase Two involved a cross-sectional internet-based administration of the scale items to a total of 1,937 women. Psychometric properties of the scale were evaluated through the use of reliability analysis, factor analysis, and score differences based on women's experience of orgasm from receiving cunnilingus or from self-masturbation with a vibrator. Correlation analysis was used to explore the relationship between female genital self-image and scores on the Female Sexual Function Index (FSFI). The scale was found to have sufficient reliability (Cronbach's alpha = 0.88) and one factor that explained 59.23% of the variance. Women who had ever experienced orgasm as a result of cunnilingus or self-masturbation with a vibrator and women who reported having had a gynecological exam in the previous 12 months had significantly higher FGSIS scores than those who had not (P self-image was found to be positively related to women's sexual function.

    Hope has received attention as a central component of recovery from mental illness; however, most instruments measuring hope were developed outside the mental health field. To measure the effects of mental health programs on hope in people with schizophrenia, a specialized scale is needed. This study examined the psychometric properties of the newly developed 9-item Schizophrenia Hope Scale (SHS-9) designed to measure hope in individuals with schizophrenia. A descriptive survey design. Participants were recruited from three psychiatric hospitals and two community mental health centers in South Korea. A total of 347 individuals over age 18 with a DSM-IV diagnosis of schizophrenia, schizoaffective, or schizophrenia spectrum disorders (competent to provide written informed consent) participated in this study; 149 (94 men, 55 women) completed a preliminary scale consisting of 40 revised items, and 198 (110 men, 88 women) completed the second scale of 17 items. Scale items were first selected from extensive literature reviews and a qualitative study on hope in people with schizophrenia; the validity and reliability of a preliminary scale was then evaluated by an expert panel and exploratory factor analysis. The remaining 9 items forming the Schizophrenia Hope Scale (SHS-9) were evaluated through confirmatory factor analysis. The SHS-9 demonstrates promising psychometric integrity. The internal consistency alpha coefficient was 0.92 with a score range of 0-18 and a mean total score of 12.06 (SD=4.96), with higher scores indicating higher levels of hope. Convergent validity was established by correlating the SHS-9 to the State-Trait Hope Inventory, r=0.61 (phope accounting for 61.77% of the total item variance. As hope has been shown to facilitate recovery from mental illness, the accurate assessment of hope provided by the short, easy-to-use Schizophrenia Hope Scale (SHS-9) may aid clinicians in improving the quality of life of individuals with schizophrenia.

    The USA National Phenology Network (USA-NPN; www.usanpn.org) is now producing and freely delivering daily maps and short-term forecasts of accumulated growing degree days and spring onset dates (based on the Extended Spring Indices) at fine spatial scale for the conterminous United States. These data products have utility for a wide range of natural resource planning and management applications, including scheduling invasive species and pest detection and control activities, determining planting dates, anticipating allergy outbreaks and planning agricultural harvest dates. Accumulated growing degree day (AGDD) maps were selected because accumulated temperature is a strong driver of phenological transitions in plants and animals, including leaf-out, flowering, fruit ripening and migration. The Extended Spring Indices (SI-x) are based on predictive climate models for lilac and honeysuckle leaf and bloom; they have been widely used to summarize changes in the timing of spring onset. The SI-x is used as a national indicator of climate change impacts by the US Global Change Research Program and the Environmental Protection Agency. The USA-NPN is a national-scale program that supports scientific advancement and decision-making by collecting, storing, and sharing phenology data and information. To best serve various audiences, the AGDD and SI-x gridded maps are available in various formats through a range of access tools, including the USA-NPN online visualization tool as well as industry standards compliant web services. We plan to expand the suite of gridded map products offered by the USA-NPN to include predictive maps of phenological transitions for additional plant and animal species at fine spatial and temporal resolution in the near future. USA-NPN invites you to use freely available daily and short-term forecast maps of accumulated growing degree days and spring onset dates at fine spatial scale for the conterminous United States.

    Effective management of Hoarding Disorder (HD) must begin with assessment of the severity of hoarding symptoms and functional impairment. We sought to validate the UCLA Hoarding Severity Scale (UHSS), a semi-structured, clinician-administered rating scale that measures the severity of both the core symptoms of HD and the associated features of indecisiveness, perfectionism, task prolongation, and procrastination, which are significantly associated with the diagnosis and impairment of HD. Hoarding symptom severity was measured in 62 patients who met DSM-5 diagnostic criteria for HD and 65 normal controls, using the UHSS and the Saving Inventory-Revised (SI-R), a well validated self-report measure of hoarding symptoms. The UHSS showed significant internal consistency (Cronbach׳s α=.70). Principal components analysis revealed three factors that accounted for 58% of the variance: 1) associated features and functional impairment, 2) clutter volume and social impairment, and 3) difficulty discarding, urges to save, and excessive acquisition. UHSS and SI-R scores were significantly correlated. UHSS and SI-R total and factor scores of HD patients were all significantly different from those of controls. Inter-rater and test-retest reliability were not assessed. The initial version of the UHSS did not contain rater instructions, so it lacked quantifiable anchor points for ratings. The UHSS showed internal consistency, construct validity, convergent validity, and known groups discriminant validity. The UHSS validly measures the core symptoms, associated features, and functional impairment of patients with HD. Utilizing a valid clinician-administered scale will provide a more comprehensive and accurate clinical assessment of patients with HD. Copyright © 2015 Elsevier B.V. All rights reserved.

    Experiencing intimate partner violence (IPV) and financial hardship are often intertwined. The dynamics of an abusive relationship may include economic abuse tactics that compromise a survivor's ability to work, pursue education, have access to financial resources, and establish financial skills, knowledge, and security. An increasingly common goal among programs serving IPV survivors is increasing financial empowerment through financial literacy. However, providing financial education alone may not be enough to improve financial behaviors. Psychological factors also play a role when individuals make financial choices. Economic self-efficacy focuses on the individual's perceived ability to perform economic or financial tasks, and may be considered a primary influence on one's ability to improve financial decisions and behaviors. The current study tests the reliability and validity of a Scale of Economic Self-Efficacy with a sample of female survivors of IPV. This study uses a calibration and validation analysis model including full and split-sample exploratory and confirmatory factor analyses, assesses for internal consistency, and examines correlation coefficients between economic self-efficacy, economic self-sufficiency, financial strain, and difficulty living with income. Findings indicate that the 10-item, unidimensional Scale of Economic Self-Efficacy demonstrates strong reliability and validity among this sample of IPV survivors. An ability to understand economic self-efficacy could facilitate individualized service approaches and allow practitioners to better support IPV survivors on their journey toward financial empowerment. Given the increase in programs focused on assets, financial empowerment, and economic well-being, the Scale of Economic Self-Efficacy has potential as a very timely and relevant tool in the design, implementation, and evaluation of such programs, and specifically for programs created for IPV survivors.

    Numerical modeling is an actual key tool in the area of geosciences. The current challenge is to solve problems that are multi-physics and for which the length scale and the place of occurrence might not be known in advance. Also, the spatial extend of the investigated domain might strongly vary in size, ranging from millimeters for reactive transport to kilometers for glacier erosion dynamics. An efficient way to proceed is to develop simple but robust algorithms that perform well and scale on modern supercomputers and permit therefore very high-resolution simulations. We propose an efficient approach to solve memory bounded real-world applications on modern supercomputers architectures. We optimize the software to run on our newly acquired state-of-the-art GPU cluster "octopus". Our approach shows promising preliminary results on important geodynamical and geomechanical problematics: we have developed a Stokes solver for glacier flow and a poromechanical solver including complex rheologies for nonlinear waves in stressed rocks porous rocks. We solve the system of partial differential equations on a regular Cartesian grid and use an iterative finite difference scheme with preconditioning of the residuals. The MPI communication happens only locally (point-to-point); this method is known to scale linearly by construction. The "octopus" GPU cluster, which we use for the computations, has been designed to achieve maximal data transfer throughput at minimal hardware cost. It is composed of twenty compute nodes, each hosting four Nvidia Titan X GPU accelerators. These high-density nodes are interconnected with a parallel (dual-rail) FDR InfiniBand network. Our efforts show promising preliminary results for the different physics investigated. The glacier flow solver achieves good accuracy in the relevant benchmarks and the coupled poromechanical solver permits to explain previously unresolvable focused fluid flow as a natural outcome of the porosity setup. In both cases

    Full Text Available Consumer-Company Identification is a relatively new issue in the marketing academia. Bhattacharya and Sen(2003 explored the Social Identity theory and established Consumer-Company Identification as the primary psychological substrate for deep relationships between the organization and its customers. In the present study a new instrument was constructed and validated that permits the empirical verification of the phenomenon described by Bhattacharya and Sen (2003. The scale validated in the present study is the first to embrace the idiosyncrasies of the identification between consumers and organizations. The process was conducted through 3 independent data collections. The first one was collected using literature search and in-depth interviews with 12 undergraduate students and bachelors from different professional fields. The second data base was obtained from a survey of 226 undergraduate students from 3 universities in 2 big Brazilian cities. This data base was used for purification purposes using Explanatory Factorial Analysis. Finally, the Structural Equation Modeling technique was applied to analyze a third data base composed of 387 observations collected from the same 3 universities of the second study. The results confirm the content, convergent and discriminant validity of the new scale proposed.

    The development and testing of a simple mechanical stemming aid is described. The aid comprises a solid unit placed in the stemming above the explosive column and is designed to improve blasting efficiency and reduce drilling and blasting costs. It is designed to work with back filled drill cuttings or any other suitable stemming material. To date it has consisted of the testing of the aid in small diameter (1.5 and 1.625 inch) holes in Jefferson City Dolomite for both bench and crater blasting configurations. Full scale field trials are being conducted nearby in similar rock in an aggregate quarry. The data acquisition equipment used in Phase 1 included both a Spin Physics SP2000 high speed video motion analysis system and acoustic and seismic monitoring units. Measurements for each test included peak air over pressure, ground surface ppv, stemming displacement and velocity and face movement and extent. The results illustrate that the concept is sound and that its successful application to production blasting at full scale will be a function of manufacturing cost, the development of suitable insertion techniques for large diameter boreholes and the selection of a suitable low cost material for the aid. 17 refs., 20 figs.

    The French orientation law on energy should be adopted very soon. It fixes ambitious objectives to develop renewable energy sources, in particular a 50% increase of the renewable heat by 2010. Despite an evident acceleration in the development of these energy sources, the path remains long before reaching the orientation law and Kyoto protocol objectives. In particular, several brakes remain to be released for the development of collective facilities (renewable heat networks). This article presents the objectives of the French government in terms of renewable energy sources development (solar thermal and photovoltaic, wood fueled and cogeneration systems) and the problems encountered so far in the implementation of this policy.

    Full Text Available : In both developed and developing countries, the government is turning to small and medium scale industries and entrepreneurs, as a means of economic development and a veritable means of solving problems. It is a seedbed of innovations, inventions and employment. Entrepreneurship is as old as Nigeria and had contributed to the growth of the economy. Presently in Nigeria, SMEs assist in promoting the growth of the country’s economy, hence all the levels of government at different times havepolicies which promote the growth and sustenance of SMEs. This paper identifies the orientation of SME’s and entrepreneurial trends in Nigeria, tackles the operational definition and scopes, and describes the role of the Nigerian government as a participant, regulator and facilitator, both legally and politically in the growth of SMEs and entrepreneurship. It identifies the marketing problems of SMEs and entrepreneurships in Nigeria, the provision and enactment of beneficial and supportive laws, the provision of infrastructural facilities, constant man-power and development, direct financial assistance to SMEs and the establishment of finance institutions to support SMEs. It identifies the roles of SMEs in Nigeria’s development and growth. It discusses the entrepreneurial thoughts, problems and advance practical marketing solution. It concludes by clearly specifying the role of marketing to the survival of SMEsand entrepreneurship in Nigeria, and relevant recommendations. For SMEs to survive marketing practice and principles must be given prominence.

    William B. Miller

    2016-09-01

    Full Text Available All eukaryotic organisms are holobionts representing complex collaborations between the entire microbiome of each eukaryote and its innate cells. These linked constituencies form complex localized and interlocking ecologies in which the specific microbial constituents and their relative abundance differ substantially according to age and environmental exposures. Rapid advances in microbiology and genetic research techniques have uncovered a significant previous underestimate of the extent of that microbial contribution and its metabolic and developmental impact on holobionts. Therefore, a re-calibration of the neonatal period is suggested as a transitional phase in development that includes the acquisition of consequential collaborative microbial life from extensive environmental influences. These co-dependent, symbiotic relationships formed in the fetal and neonatal stages extend into adulthood and even across generations.

    2010-09-15

    This article investigates the role of carbon finance and seeks to establish a policy framework that allows reorientation of upfront investment in urban infrastructure for facilitating transition towards low-carbon development trajectory in developing cities. It draws on an in-depth exploration of different climate finance mechanisms and their applicability in the context of fast urbanization. We suggest an integrated approach should be adopted to aggregate city-based multiple individual GHG mitigation projects dealing with buildings and transport efficiency. The sectoral approach and NAMAs-based financing schemes be included in post-Kyoto regime for shifting the current trajectories in fast growing developing cities.

    2015-01-10

    This paper describes a simulation of an industrial-scale fed-batch fermentation that can be used as a benchmark in process systems analysis and control studies. The simulation was developed using a mechanistic model and validated using historical data collected from an industrial-scale penicillin fermentation process. Each batch was carried out in a 100,000 L bioreactor that used an industrial strain of Penicillium chrysogenum. The manipulated variables recorded during each batch were used as inputs to the simulator and the predicted outputs were then compared with the on-line and off-line measurements recorded in the real process. The simulator adapted a previously published structured model to describe the penicillin fermentation and extended it to include the main environmental effects of dissolved oxygen, viscosity, temperature, pH and dissolved carbon dioxide. In addition the effects of nitrogen and phenylacetic acid concentrations on the biomass and penicillin production rates were also included. The simulated model predictions of all the on-line and off-line process measurements, including the off-gas analysis, were in good agreement with the batch records. The simulator and industrial process data are available to download at www.industrialpenicillinsimulation.com and can be used to evaluate, study and improve on the current control strategy implemented on this facility.

    The Health Promoting Activities Scale (HPAS) measures the frequency that mothers participate in self-selected leisure activities that promote health and wellbeing. The scale was originally validated on mothers of school-aged children with disabilities, and the current article extends this research using a comparative sample of mothers of typically developing school-aged children. Australian mothers (N = 263) completed a questionnaire containing the HPAS, a measure of depression, anxiety and stress (DASS-21) and questions concerning their weight, height, sleep quality and demographics. Statistical analysis assessed the underlying structure, internal consistency and construct validity of the HPAS. Inferential statistics were utilised to investigate the construct validity. Exploratory factor analysis supported the unidimensionality of the HPAS. It showed good internal consistency (Cronbach's alpha = 0.78). Significantly lower HPAS scores were recorded for women who were obese; had elevated levels of depression, anxiety and stress; had poor quality sleep or had heavy caring commitments. The mean HPAS score in this sample (M = 32.2) was significantly higher than was previously reported for women of children with a disability (M = 21.6: P HPAS continues to support the HPAS as a sound instrument that measures the frequency that women participate in meaningful occupation that is associated with differences in mental health and wellbeing and other health indicators. © 2014 Occupational Therapy Australia.

  6. Linking Supply Chain Network Complexity to Interdependence and Risk-Assessment: Scale Development and Empirical Investigation

    Full Text Available Concepts like supply chain network complexity, interdependence and risk assessment have been prominently discussed directly and indirectly in management literature over past decades and plenty of frameworks and conceptual prescriptive research works have been published contributing towards building the body of knowledge. However previous studies often lacked quantification of the findings. Consequently, the need for suitable scales becomes prominent for measuring those constructs to empirically support the conceptualized relationships. This paper expands the understanding of supply chain network complexity (SCNC and also highlights its implications on interdependence (ID between the actors and risk assessment (RAS in transaction relationships. In doing so, SCNC and RAS are operationalized to understand how SCNC affects interdependence and risk assessment between the actors in the supply chain network. The contribution of this study lies in developing and validating multi-item scales for these constructs and empirically establishing the hypothesized relationships in the Indian context based on firm data collected using survey–based questionnaire. The methodology followed included structural equation modeling. The study findings indicate that SCNC had significant relationship with interdependence, which in turn significantly affected risk assessment. This study carries both academic and managerial implications and provides an empirically supported framework linking network complexity with the two key variables (ID and RAS, playing crucial roles in managerial decision making. This study contributes to the body of knowledge and aims at guiding managers in better understanding transaction relationships.

    Martin, Lisa A; Hassinger, Jane A; Seewald, Meghan; Harris, Lisa H

    We report on the development of a scale measuring abortion providers' experiences of stigma. Using previous measures, qualitative data, and expert review, we created a 49-item question pool. We administered questions to 315 abortion providers before participation in the Providers Share Workshop. We explored the factor structure and item quality using exploratory factor analysis. We assessed reliability using Cronbach's alpha. To test construct validity, we calculated Pearson's correlation coefficients between the stigma scales, the Maslach Burnout Inventory, and the K10 measure of psychological distress. We used Stata SE/12.0 for analyses. Factor analysis revealed a 35-item, five-factor model: worries about disclosure, internalized states, social judgment, social isolation, and discrimination (Cronbach's alphas 0.79-0.94). Our stigma measure was correlated with psychological distress (r = 0.40; p stigma in abortion providers, and may be helpful in evaluating stigma reduction programs.

    2010-12-01

    The purpose was to develop a preliminary scale to measure Korean adolescents' health behaviors through a qualitative approach, to evaluate the scale psychometrically, and to develop a final scale. Participants were 61 adolescents for qualitative interviews and 1,687 adolescents for the psychometric evaluation. Procedure included content analysis of interviews to identify health behavior categories for Korean adolescents, pre-test to confirm that preliminary scale items were understandable, content validity by an expert panel, development of the web-based computer-assisted survey (CAS), and psychometric analysis to determine reliability and validity of the final scale. A final scale was developed for both paper-and-pencil and CAS. It consisted of 14 health behaviors (72 items), including stress and mental health (10), sleep habits (5), dietary habits (12), weight control (4), physical activity (4), hygiene habits (5), tobacco use (5), substance use (2), alcohol consumption (4), safety (4), sexual behavior (9), computer use (3), health screening (4), and posture (1). The scale's strong points are: 1) Two thirds of the final scale items are Likert scale items, enabling calculation of a health behavior score. 2) The scale is appropriate to Korean culture. 3) The scale focuses on concrete health behaviors, not abstract concepts.

    Growing data sets with increased time for analysis is hampering predictive modeling in drug discovery. Model building can be carried out on high-performance computer clusters, but these can be expensive to purchase and maintain. We have evaluated ligand-based modeling on cloud computing resources where computations are parallelized and run on the Amazon Elastic Cloud. We trained models on open data sets of varying sizes for the end points logP and Ames mutagenicity and compare with model building parallelized on a traditional high-performance computing cluster. We show that while high-performance computing results in faster model building, the use of cloud computing resources is feasible for large data sets and scales well within cloud instances. An additional advantage of cloud computing is that the costs of predictive models can be easily quantified, and a choice can be made between speed and economy. The easy access to computational resources with no up-front investments makes cloud computing an attractive alternative for scientists, especially for those without access to a supercomputer, and our study shows that it enables cost-efficient modeling of large data sets on demand within reasonable time.

  11. Development of the scale for measuring fear from obesity

    2016-01-01

    Full Text Available Introduction: Obesity represents cumulation of adipose tissue to the extent that it decreases physical activity and psychosocial well-being, and Body Mass Index is > 30. In obese males adipose tissue makes 20% or more of the total body weight, while this percentage in females is 25%. According to epidemiological data more than half of the adult population of Serbia (54% has a problem with obesity or pre-obesity. Objective: The aim of this study was creation of a questionnaire which will measure fear of obesity reliably and accurately. Materials and Methods: The study involved the students of medicine and pharmacy from all years at the Faculty of Medical Sciences, University of Kragujevac. They were offered to express their level of agreement with the statements from the survey (21 in total using a Likert scale, which provided seven answers. After collecting the data, a statistical analysis was performed using IBM SPSS Statistics 18. Results: Within the first reliability analysis, a correlation matrix was constructed, which was used to assess whether any of the questions should be eliminated. The value of Cronbach's alpha was 0.871. After the exploratory factor analysis, five factors were revealed: fear, social effects, avoiding meals, eating habits and diet. Conclusion: The questionnaire created in this study measures fear from obesity with satisfactory reliability, but further studies are necessary to test its validity.

  12. Assessing motivation orientations in schizophrenia: Scale development and validation.

    2015-01-30

    Motivation deficits are common in several disorders including schizophrenia, and are an important factor in both functioning and treatment adherence. Self-Determination Theory (SDT), a leading macro-theory of motivation, has contributed a number of insights into how motivation is impaired in schizophrenia. Nonetheless, self-report measures of motivation appropriate for people with severe mental illness (including those that emphasize SDT) are generally lacking in the literature. To fill this gap, we adapted and abbreviated the well-validated General Causality Orientation Scale for use with people with schizophrenia and with other severe mental disorders (GCOS-clinical populations; GCOS-CP). In Study 1, we tested the similarity of our measure to the existing GCOS (using a college sample) and then validated this new measure in a schizophrenia and healthy control sample (Study 2). Results from Study 1 (N=360) indicated that the GCOS-CP was psychometrically similar to the original GCOS and provided good convergent and discriminant validity. In Study 2, the GCOS-CP was given to individuals with (N=44) and without schizophrenia (N=42). In line with both laboratory-based and observer-based research, people with schizophrenia showed lower motivational autonomy and higher impersonal/amotivated orientations. Additional applications of the GCOS-CP are discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    1997-11-12

    The focus of this work is the production of 2-mm P{alpha}MS mandrels by microencapsulation for use as National Ignition Facility (NIF) laser targets. It is our findings thus far that the processing techniques used previously for the 0.5-mm and 1.0-mm targets are no longer useful for preparation of the larger targets for a few fundamental reasons. The driving force for sphericity (from the minimization of interracial energy) decreases as the radius of curvature increases. Simultaneously, the mechanical robustness /stability of the water-oil-water emulsion droplets decreases as the droplet size increases. The impact of these physical conditions and the possibilities of circumventing these limitations have been examined while attempting to meet the NIF shell power spectrum criteria. Identifying the key parameters in the transition (solidification) from a w-o-w droplet to a solid polymer shell has been understood implicitly to be the paramount goal. It is believed through the knowledge gained that it will be possible to minimize the deleterious forces and maximize shell sphericity. At this point it is believed that properties intrinsic to the polymer (i.e., P{alpha}MS) such as its solution behavior and evolution of film stresses control the overall shell sphericity.

    2007-01-01

    Objective To develop and assess the reliability and construct validity of a scale assessing disability involving the mouth in systemic sclerosis (SSc). Methods We generated a 34‐item provisional scale from mailed responses of patients (n = 74), expert consensus (n = 10) and literature analysis. A total of 71 other SSc patients were recruited. The test–retest reliability was assessed using the intraclass coefficient correlation and divergent validity using the Spearman correlation coefficient. Factor analysis followed by varimax rotation was performed to assess the factorial structure of the scale. Results The item reduction process retained 12 items with 5 levels of answers (total score range 0–48). The mean total score of the scale was 20.3 (SD 9.7). The test–retest reliability was 0.96. Divergent validity was confirmed for global disability (Health Assessment Questionnaire (HAQ), r = 0.33), hand function (Cochin Hand Function Scale, r = 0.37), inter‐incisor distance (r = −0.34), handicap (McMaster‐Toronto Arthritis questionnaire (MACTAR), r = 0.24), depression (Hospital Anxiety and Depression (HAD); HADd, r = 0.26) and anxiety (HADa, r = 0.17). Factor analysis extracted 3 factors with eigenvalues of 4.26, 1.76 and 1.47, explaining 63% of the variance. These 3 factors could be clinically characterised. The first factor (5 items) represents handicap induced by the reduction in mouth opening, the second (5 items) handicap induced by sicca syndrome and the third (2 items) aesthetic concerns. Conclusion We propose a new scale, the Mouth Handicap in Systemic Sclerosis (MHISS) scale, which has excellent reliability and good construct validity, and assesses specifically disability involving the mouth in patients with SSc.

    Boulanger, Karen T.; Campo, Shelly; Glanville, Jennifer L.; Lowe, John B; Yang, Jingzhen

    2012-01-01

    Background: Although there is evidence that client expectations influence client outcomes, a valid and reliable scale for measuring the range of client expectations for both massage therapy and the behaviors of their massage therapists does not exist. Understanding how client expectations influence client outcomes would provide insight into how massage achieves its reported effects. Purpose: To develop and validate the Client Expectations of Massage Scale (CEMS), a measure of clients’ clinical, educational, interpersonal, and outcome expectations. Setting: Offices of licensed massage therapists in Iowa. Research Design: A practice-based research methodology was used to collect data from two samples of massage therapy clients. For Sample 1, 21 volunteer massage therapists collected data from their clients before the massage. Factor analysis was conducted to test construct validity and coefficient alpha was used to assess reliability. Correlational analyses with the CEMS, previous measures of client expectations, and the Life Orientation Test–Revised were examined to test the convergent and discriminant validity of the CEMS. For Sample 2, 24 massage therapists distributed study materials for clients to complete before and after a massage therapy session. Structural equation modeling was used to assess the construct, discriminant, and predictive validity of the CEMS. Participants: Sample 1 involved 320 and Sample 2 involved 321 adult massage clients. Intervention: Standard care provided by licensed massage therapists. Main Outcomes: Numeric Rating Scale for pain and Positive and Negative Affect Schedule–Revised (including the Serenity subscale). Results: The CEMS demonstrated good construct, convergent, discriminant and predictive validity, and adequate reliability. Client expectations were generally positive toward massage and their massage therapists. Positive outcome expectations had a positive effect on clients’ changes in pain and serenity. High

    Among older people in developed countries, social isolation leading to solitary death has become a public health issue of vital importance. Such isolation could be prevented by monitoring at-risk individuals at the neighborhood level and by implementing supportive networks at the community level. However, a means of measuring community confidence in these measures has not been established. This study is aimed at developing the Community's Self-Efficacy Scale (CSES; Mimamori scale in Japanese) for community members preventing social isolation among older people. The CSES is a self-administered questionnaire developed on the basis of Bandura's self-efficacy theory. The survey was given to a general population (GEN) sample (n = 6,000) and community volunteer (CVOL) sample (n = 1,297). Construct validity was determined using confirmatory factor analysis. Internal consistency was calculated using Cronbach's alpha. The Generative Concern Scale (GCS-R) and Brief Sense of Community Scale (BSCS) were also administered to assess criterion-related validity of the CSES. In total, 3,484 and 859 valid responses were received in the GEN and CVOL groups, respectively. The confirmatory factor analysis identified eight items from two domains-community network and neighborhood watch-with goodness of fit index = 0.984, adjusted goodness of fit index = 0.970, comparative fit index = 0.988, and root mean square error of approximation = 0.047. Cronbach's alpha for the entire CSES was 0.87 and for the subscales was 0.80 and higher. The score of the entire CSES was positively correlated with the GCS-R in both the GEN (r = 0.80, p social isolation among older people. The scale is potentially useful for promoting health policies, practices, and interventions within communities. This may help prevent social isolation among older people and contribute to overall well-being in aging societies in Japan and abroad.

    2014-04-01

    To develop a Critical Thinking Skill Test for Nursing Students. The construct concepts were drawn from a literature review and in-depth interviews with hospital nurses and surveys were conducted among students (n=607) from nursing colleges. The data were collected from September 13 to November 23, 2012 and analyzed using the SAS program, 9.2 version. The KR 20 coefficient for reliability, difficulty index, discrimination index, item-total correlation and known group technique for validity were performed. Four domains and 27 skills were identified and 35 multiple choice items were developed. Thirty multiple choice items which had scores higher than .80 on the content validity index were selected for the pre test. From the analysis of the pre test data, a modified 30 items were selected for the main test. In the main test, the KR 20 coefficient was .70 and Corrected Item-Total Correlations range was .11-.38. There was a statistically significant difference between two academic systems (p=.001). The developed instrument is the first critical thinking skill test reflecting nursing perspectives in hospital settings and is expected to be utilized as a tool which contributes to improvement of the critical thinking ability of nursing students.

    2012-11-01

    Full Text Available A new scale measuring patient-therapist attachment avoidance was developed. Attachment Avoidance in Therapy Scale is a new measure based on the Bartholomew model of adult attachment (Bartholomew & Horowitz, 1991 and the Experience in Close Relationships Scale (Brennan, Clark, & Shaver, 1998 to measure patients’ attachment avoidance towards therapists. With 112 patient-therapist dyads participating in the study, validation of a preliminary scale – measuring both attachment anxiety and attachment avoidance in therapy – took place using therapists’ evaluations of patients’ relational behavior and patients’ self-reports about their attitude toward psychotherapy. Analysis of the data revealed six underlying scales. Results showed all six scales to be reliable. Validation of scales measuring attachment anxiety failed. The importance of Attachment Avoidance in Therapy Scale and its subscales is discussed.

    Akerjordet, Kristin; Severinsson, Elisabeth

    2009-03-01

    This article, the first in a series of four, describes the development of two scales for deductive and inductive measurement of emotional intelligence (EI), based on the literature and the identification of the psychometric properties of the scales. The data collection comprised two parts: (i) a literature search on the subject of emotional intelligence; and (ii) psychometric testing of the scales. The Emotional Intelligence Scale, comprising 23 items, and the Emotional Reactions and Thoughts Scale, containing 25 items, were tested on a sample of 250 postnatal mothers. The response rate was 80%. An explorative factor analysis was used to investigate the construct validity of the underlying dimensions of emotional intelligence and yielded a three-factor solution for the Emotional Intelligence Scale and a four-factor solution for the Emotional Reactions and Thoughts Scale. The internal consistency of the scales was satisfactory. How well the factor solutions fit in clinical practice remains to be validated.

  4. Overcoming Ex-Post Development Stagnation: Interventions with Continuity and Scaling in Mind

    Full Text Available Project interventions are important vehicles for development globally. However, while there is often allocation of resources for new and innovative (pilot projects—with varying levels of success—there is seemingly less focus on consolidating and/or scaling the positive impacts of successful larger interventions. Assuming an overarching development goal to have long lasting impact at scale, this approach seems somewhat contradictory. Scaling is often not integrated into project planning, design and implementation and rarely pursued genuinely in the ex-post. However, where demand for further development remains outstanding beyond project completion, opportunities may exist to build upon project platforms and extend benefits in a cost effective manner. This paper examines existing scaling typologies, before introducing “scaling-within” as a concept to promote greater continuity of development to a wider range of stakeholders. Scaling-within offers the opportunity to “in-fill” intervention principles and practices to both project and non-project communities within a broader strategic framework to address disparities and to promote sustainable development. The authors draw on research from case studies of large-scale integrated watershed rehabilitation projects and assess scaling-within against a contemporary scaling framework drawn from the literature. While the concept is tested with watersheds as the administrative unit, the authors anticipate applications for other project management units.

    The Japanese Maternal Breastfeeding Evaluation Scale (JMBFES) was developed in 2013 based on the original Maternal Breastfeeding Evaluation Scale (MBFES). Mothers' abilities to incorporate breastfeeding into their daily life may influence their decision to continue or discontinue to breastfeed, but that version of the JMBFES had no questions to measure this important aspect of breastfeeding. Therefore, we sought to improve the JMBFES by incorporating questions measuring "lifestyle compatibility-incompatibility," and we conducted psychometric testing of the improved version. In this longitudinal study, the revised JMBFES was developed, and its reliability and validity was tested among 215 Japanese mothers. In the first survey, which was done three months after delivery, infant-feeding status and the prenatal intention regarding breastfeeding were measured. In the second survey, which was done two months later, the JMBFES questions were asked along with questions regarding infant-feeding status. We identified items that could be deleted while maintaining high reliability. Using regression models, we examined associations of JMBFES scores with breastfeeding intention and breastfeeding outcomes. All three subscales in the revised JMBFES had acceptable reliability (alpha >=0.78). The two "lifestyle compatibility-incompatibility" items (one new item and the one that had been deleted previously) belonged to the "potentially negative aspects" subscale. Scores on that subscale were not associated with breastfeeding intention. However, in both surveys, the mothers who were using formula reported more potential difficulties (p<=0.01). Results of validation testing and reliability testing indicate that the revised JBFEES can be used to measure breastfeeding satisfaction among Japanese mothers.

    Spaulding, Aaron; Kash, Bita A; Johnson, Christopher E; Gamm, Larry

    We do not have a strong understanding of a health care organization's capacity for attempting and completing multiple and sometimes competing change initiatives. Capacity for change implementation is a critical success factor as the health care industry is faced with ongoing demands for change and transformation because of technological advances, market forces, and regulatory environment. The aim of this study was to develop and validate a tool to measure health care organizations' capacity to change by building upon previous conceptualizations of absorptive capacity and organizational readiness for change. A multistep process was used to develop the organizational capacity for change survey. The survey was sent to two populations requesting answers to questions about the organization's leadership, culture, and technologies in use throughout the organization. Exploratory and confirmatory factor analyses were conducted to validate the survey as a measurement tool for organizational capacity for change in the health care setting. The resulting organizational capacity for change measurement tool proves to be a valid and reliable method of evaluating a hospital's capacity for change through the measurement of the population's perceptions related to leadership, culture, and organizational technologies. The organizational capacity for change measurement tool can help health care managers and leaders evaluate the capacity of employees, departments, and teams for change before large-scale implementation.

    The 350-m thick succession of the late-Pleistocene Po River Lowstand Delta (PRLD) deposited in just 17 k.y. encompassing the Last Glacial Maximum and contains stratal architecture at a physical scale commonly attributed to much longer time intervals, with complex, systematically varying internal clinothem characteristics. We document clinothem characteristics, stacking patterns, and controls through the integration of seismic-reflection data with sediment attributes, micropaleontology, regional climate, eustacy, and high-resolution age control on the PRLD. Within the PRLD, three clinothem types are characterized by distinctive topset geometry, shelf-edge and onlap-point trajectory, internal seismic facies, and interpreted bottomset deposits: Type A) moderate topset aggradation, ascending shelf-edge trajectories, and thin mass-transport bottomset deposits; Type B) eroded topset, descending shelf-edge trajectories, and bottomset distributary channel-lobe complexes; and Type C) maximal topset aggradation, ascending shelf-edge trajectories, and draped concordant bottomsets. Measured sediment accumulation rates suggest that Type A and C clinothems experienced reduced sediment bypass and delivery to the basin, whereas, Type B clinothems were associated with short intervals of increased sediment export from the shelf to deep water and development of distributary channel-lobe complexes. This interpretation is supported by micropaleontological analyses that highlight increased delivery of sediment and fresh water to the basin during the progradation of Type B clinothems, as suggested by the reduced occurrence of Cassidulina laevigata carinata and the peak abundance of Nonion spp. Each clinothem formed in a very short interval, from 0.4 to 4.7 k.y., contemporaneous with significant eustatic and climate changes. While changes in stacking patterns at these temporal scales have previously been observed in modern deltaic clinothems, the significance of our study is that we have

    People in romantic relationships can develop shared memory systems by pooling their cognitive resources, allowing each person access to more information but with less cognitive effort. Research examining such memory systems in romantic couples largely focuses on remembering word lists or performing lab-based tasks, but these types of activities do not capture the processes underlying couples' transactive memory systems, and may not be representative of the ways in which romantic couples use their shared memory systems in everyday life. We adapted an existing measure of transactive memory systems for use with romantic couples (TMSS-C), and conducted an initial validation study. In total, 397 participants who each identified as being a member of a romantic relationship of at least 3 months duration completed the study. The data provided a good fit to the anticipated three-factor structure of the components of couples' transactive memory systems (specialization, credibility and coordination), and there was reasonable evidence of both convergent and divergent validity, as well as strong evidence of test-retest reliability across a 2-week period. The TMSS-C provides a valuable tool that can quickly and easily capture the underlying components of romantic couples' transactive memory systems. It has potential to help us better understand this intriguing feature of romantic relationships, and how shared memory systems might be associated with other important features of romantic relationships.

    Full Text Available Background: Happiness as one of the main positive health indicators has drawn more attention in recent years among policy makers and health system managers. There are few studies performed to measure happiness in population-based settings in Iran. In response to this need, our study tends to assess Iranians subjective happiness in Tehran, Capital city of Iran.Materials and Methods: Present study was conducted in Tehran, Capital of Iran, with more than 7 Million populations in January 2013, using a two-step approach. In first step c conceptual framework of Iranians’ happiness was developed. In the second phase of study, a survey recruiting 700 participants was conducted. Stratified cluster sampling method was employed. Participants were recruited from all the 22 municipal divisions of Tehran as strata, proportional to the population size and its gender and age distribution. Happiness was measure by a 40-item questionnaire with scores ranged among 40 to 200.Results: Conceptual framework of Iranians’ happiness based on reviewed documents and consensus building process was the product of first step. At second step, from a pool of 700 persons, 696 (97% agreed to participate and filled out the questionnaire completely.  The mean of happiness score was 143.9 (95% confidence interval, 142.5 to 145.4. The results show that the happiness score of jobless people (135.1, 95%CI: 128.1-142.0 and widowed singles (126.6, 95%CI: 113.0-140.2 were significantly lower than other corresponding groups. There was no significant association between gender, age group, educational level as determinants and happiness.Conclusion: Happiness level of Tehranians is somewhat higher than the moderate level. This finding is consistent with findings of other conducted studies in country. However, it is not consistent with some of international reports of happiness, For instance, Happy Planet Index. Due to inadequate information, it is necessary to conduct more research to

    In the context of professional nursing, the concept of job satisfaction includes the degree to which a nurse is satisfied with the nursing profession, his/her personal adaptation to this profession, and his/her current working environment. No validated scale that addresses the job satisfaction of nurses working in hospitals currently exists in Taiwan. To develop a reliable and validated scale for measuring the job satisfaction of hospital nurses in Taiwan. A three-phase, cross-sectional study design was used. First, a literature review and expert focus group discussion were conducted to develop the initial scale items. Second, experts were invited to validate the content of the draft scale. Finally, convenience sampling was used to recruit 427 hospital nurses from 6 hospitals. These nurses completed the scale and the results were analyzed using item analysis, factor analysis, and internal consistency analysis. The 31-item Taiwanese hospital nurse job satisfaction scale developed in the present study addresses 5 factors, including supportive working environment, professional autonomy and growth, interpersonal interaction and collaboration, leadership style, and nursing workload. The overall Cronbach's α was .96. The results indicate that the developed scale provides good reliability and validity. This study confirms the validity and reliability of the developed scale. It may be used to measure the job satisfaction of nurses working in hospitals.

    Full Text Available In Russia small-scale business originated in the end of 1980s duringRestructuring. It has been developing as fast as Russian economics.Unlike large industrial companies, which just continued to run businessas they used to, small-scale businessmen had to start from scratch ordisaffiliate with large organizations. Basically, in 1990-s small-scale business as a financial institute was self-regulated due to its highcriminalization and nonpayment of tax.For a period of only 25 years small-scale business has improved muchand now provides well-being to the country. The improvement happeneddue to the following factors:- propitious economic and political climate of the country against thebackground of global economy and the years of restricting- important and useful measures for economic development were taken - important and useful measures for development of small-scale enterprises were takenThe development of this new financial institute is quite fast, but historyhas other examples of such phenomenon. In the 21st century RussianFederation adopted experience of advanced countries and imposed it onits historic experience. However, we can’t say that small-scale business is on its top of development in our country. Nowadays development of small-scale business is one of the priorities of the Russian government.

    Although patients prefer that physicians initiate advance care planning (ACP) conversations, few physicians regularly do so. Physicians may be reluctant to initiate ACP conversations because they lack self-efficacy in their skills. Yet, no validated scale on self-efficacy for ACP exists. Our objective was to develop a scale that measures physicians' ACP self-efficacy (ACP-SE) and to investigate the validity of the tool. Electronic questionnaires were administered to a random sample of family medicine physicians (n = 188). Exploratory factor analysis was performed to determine whether the scale was multidimensional. An initial assessment of the scale's validity was also conducted. The exploratory factor analysis indicated that a single factor was appropriate using all 17 items. A single, unidimensional scale was created by averaging the 17 items, yielding good internal consistency (Cronbach α = 0.95). The average scale score was 3.94 (standard deviation = 0.71) on a scale from 1 to 5. The scale was moderately correlated with a global single-item measure of self-efficacy for ACP ( r = .79, P < .001), and the scale differentiated between physician groups based on how much ACP they were doing, how recently they had an ACP conversation, formal training on ACP, and knowledge of ACP. In a multivariate analysis, the ACP-SE scale was a strong predictor of the percentage of patients with chronic life-limiting diseases with whom the physician discussed ACP. The final ACP-SE scale included 17 items and demonstrated high internal consistency.

    cleanup responses, has a sound approach for decontamination decision-making that has been applied several times. The anthrax contamination at the U. S. Hart Senate Office Building and numerous U. S. Post Office facilities are examples of employing novel technical responses. Decontamination of the Hart Office building required development of a new approach for high level decontamination of biological contamination as well as techniques for evaluating the technology effectiveness. The World Trade Center destruction also demonstrated the need for, and successful implementation of, appropriate cleanup methodologies. There are a number of significant lessons that can be gained from a look at previous large scale cleanup projects. Too often we are quick to apply a costly “package and dispose” method when sound technological cleaning approaches are available. Understanding historical perspectives, advanced planning and constant technology improvement are essential to successful decontamination.

  11. Reduction of Bacterial Pathogenic Risk during Ex-situ Stabilization of Previously Buried Foot-and-Mouth Disease Carcasses in a Pilot-scale Bio-augmented Aerobic Composting

    Foot and mouth disease outbreaks globally occur. Although livestock suspected to be infected or actually infected by animal infectious diseases is typically treated with various methods including burial, burning, incineration, rendering, and composting, burial into soil is currently the major treatment method in Korea. However, buried carcasses are often found to remain undecomposed or incompletely decomposed even after the legal burial period (3 years). To reuse the land used for the burial purposes, Korea government is considering a novel approach to conduct in-situ burial treatment and then to move remaining carcasses from the burial sites to other sites designated for further ex-situ stabilization treatment (burial-composting sequential treatment). In this work, the feasibility of the novel approach was evaluated at a pilot scale facility. For the ex-situ stabilization, we tested the validity of use of a bio-augmented aerobic composting with carcass-degrading microorganisms, with emphasis on examining if the novel aerobic composting has reducing effects on potential pathogenic bacteria. As results, the decreased chemical oxygen demand (COD, 160,000 mg/kg to 40,000 mg/kg) and inorganic nitrogen species (total nitrogen, 5,000 mg/kg to 2,000 mg/kg) indicated effective bio-stabilization of carcasses. During the stabilization, bacterial community structure and dynamics determined by bacterial 16S rRNA sequencing were significantly changed. The prediction of potential pathogenic bacteria showed that bacterial pathogenic risk was significantly reduced up to a normal soil level during the ex-situ stabilization. The conclusion was confirmed by the following functional analysis of dominant bacteria using PICRUST. The findings support the microbiological safety of the ex-site use of the novel burial-composting sequential treatment.

We examine a suite of such variables and find that convective available potential energy and cloud top height give the best estimates compared to July 2010 observations from ground-based lightning observation networks. Previous models often use lightning NOx vertical profiles derived from cloud-resolving model simulations. An implicit assumption of such an approach is that the postconvection lightning NOx vertical distribution is the same for all deep convection, regardless of geographic location, time of year, or meteorological environment. Detailed observations of the lightning channel segment altitude distribution derived from the NASA Lightning Nitrogen Oxides Model can be used to obtain the LNOx emission profile. Coupling such a profile with model convective transport leads to a more self-consistent lightning distribution compared to using prescribed postconvection profiles. We find that convective redistribution appears to be a more important factor than preconvection LNOx profile selection, providing another reason for linking the strength of convective transport to LNOx distribution.

    Previous research has demonstrated modest benefits from music-based interventions, specifically music and imagery interventions, during cancer care. However, little attention has been paid to measuring the benefits of music-based interventions using measurement instruments specifically designed to account for the multidimensional nature of music-imagery experiences. The purpose of this study was to describe the development of, and psychometrically evaluate, the Music Therapy Self-Rating Scale (MTSRS) as a measure for cancer patients engaged in supportive music and imagery interventions. An exploratory factor analysis using baseline data from 76 patients who consented to participate in a music-based intervention study during chemotherapy. Factor analysis of 14 items revealed four domains: Awareness of Body, Emotionally Focused, Personal Resources, and Treatment Specific. Internal reliability was excellent (Cronbach alphas ranging from 0.75 to 0.88) and construct and divergent-discriminant validity supported. The MTSRS is a psychometrically sound, brief instrument that captures essential elements of patient experience during music and imagery interventions. © the American Music Therapy Association 2015.

    This study aimed to develop and validate a scale to measure perceived stigma for perinatal mental illness in women. Stigma is one of the most frequently cited barriers to seeking treatment and many women with perinatal mental illness fail to get the treatment they need. However, there is no psychometric scale that measures how women may experience the unique aspects of perinatal mental illness stigma. A draft scale of 30 items was developed from a literature review. Women with perinatal mental illness (n = 279) were recruited to complete the City Mental Illness Stigma Scale. Concurrent validity was measured using the Internalised Stigma of Mental Illness Scale. Factor analysis was used to create the final scale. The final 15-item City Mental Illness Stigma Scale has a three-factor structure: perceived external stigma, internal stigma and disclosure stigma. The scale accounted for 54% of the variance and had good internal reliability and concurrent validity. The City Mental Illness Stigma Scale appears to be a valid measure which provides a potentially useful tool for clinical practice and research in stigma and perinatal mental illness, including assessing the prevalence and characteristics of stigma. This research can be used to inform interventions to reduce or address the stigma experienced by some women with perinatal mental illness.

    The aim of the current study was to translate the Hung Postpartum Stress Scale into Turkish and test the reliability and validity of the Turkish version of the scale. The translation process of the Hung Postpartum Stress Scale into Turkish and the testing of reliability and validity of the newly developed scale on postpartum stress in women are described. The questionnaire was translated using a back-translation technique. Expert review of internal consistency reliability, content validity, factor analysis of construct validity and criterion-related validity were examined. Cronbach's alpha for the Turkish version of the Hung Postpartum Stress Scale was 0.931, indicating very good reliability. Factor analyses resulted in a two factor scale structure: maternal concerns and acceptability of the newborn by the family. Analyses also indicated good test-re-test reliability for the Turkish version of the Hung Postpartum Stress Scale (P design of a Turkish version of the Hung Postpartum Stress Scale. The newly developed scale proved to be reliable and valid and will be a valuable instrument for women's healthcare professionals. © 2012 The Authors.

    To develop psychosocial adaptation scale for Parkinson's disease (PD) in Chinese population and evaluate its reliability and validity. The items were designed by literature review, expert consultation and semi-structured interview. The methods of corrected item-total correlation, discrimination analysis and exploratory factor analysis were used for items selection. 427 valid scales from PD patients were collected in the study to test the reliability and validity. The scale incorporated six dimensions: anxiety, self-esteem, attitude, self-acceptance, self-efficacy and social support, a total of 32 items. The scale possessed good internal consistency. The test-retest correlation coefficient was 0.99 and average content validation rate was 0.97. The Hoehn and Yahr stage were correlated with total score of the scale. The psychosocial adaptation scale in this study showed good reliability and validity, it can be used as a reliable and valid instrument to evaluate the psychosocial adaptation of PD objectively and effectively.

    There are many studies about social skills and social skills training in Japan, most of which include listening skills among the target skills. Listening skills are important for adolescents because they are necessary to start and cultivate relationships with friends. The present study developed a revised version of listening skills scales for high school students, and confirmed their reliability and validity. Listening skills consist of two domains: cognitive skills and behavioral skills. Because these two domains are conceptually independent, a cognitive skills scale and a behavioral skills scale were constructed separately. Based on factor analyses, three cognitive and five behavioral subscales were constructed. These scales had sufficient internal consistency and showed positive relationships between empathy, social self-regulation, and other social skills scales. Further applications of these scales were discussed.

    Full Text Available This study aimed to develop a scale to evaluate teacher candidates' level of being affected from the public personnel selection examination. The participants of the study consisted of the final year students at Pamukkale University Education Faculty. The participants were 207 teacher candidates, of whom 143 were female and 64 were male. The validity and reliability study of the scale was conducted on the data gathered from teacher candidates studying at Art Teaching, Music Teaching, Turkish Language Teaching, Social Studies Education, Science Teaching, Psychological Counseling and Guidance Education, Elementary Education and Preschool Education departments of Pamukkale University Education Faculty. The Lawshe technique was used in the evaluation of the scale by experts. To determine the construct validity, factor analysis was performed on the data, and two sub-scales were identified. The factor loading values of the items in the first sub-scale ranged between 0,65 and 0,35, and those in the second sub-scale between 0,75 and 0,39. As a result of the analyses, the "Teacher Candidates' Level of Being Affected From Public Personnel Selection Examination Scale" (TCLBAPPSES including 33 items, 23 negative and 10 positive, and two sub-scales was produced. The Cronbach's Alpha reliability coefficient was found as 0,86 for the first sub-dimension, 0,73 for the second sub-dimension, and 0,91 for the whole scale. As a result, it can be argued that the scale is reliable

    To develop an assessment method of active aging for research on older people. A multiphase process that included drafting by an expert panel, a pilot study for item analysis and scale validity, a feedback study with focus groups and questionnaire respondents, and a test-retest study. Altogether 235 people aged 60 to 94 years provided responses and/or feedback. We developed a 17-item University of Jyvaskyla Active Aging Scale with four aspects in each item (goals, ability, opportunity, and activity; range 0-272). The psychometric and item properties are good and the scale assesses a unidimensional latent construct of active aging. Our scale assesses older people's striving for well-being through activities pertaining to their goals, abilities, and opportunities. The University of Jyvaskyla Active Aging Scale provides a quantifiable measure of active aging that may be used in postal questionnaires or interviews in research and practice.

    The Barthel Index (BI) assesses actual performance of activities of daily living (ADL). However, comprehensive assessment of ADL functions should include two other constructs: self-perceived difficulty and ability. The aims of this study were to develop two BI-based Supplementary Scales (BI-SS), namely, the Self-perceived Difficulty Scale and the Ability Scale, and to examine the construct validity of the BI-SS in patients with stroke. The BI-SS was first developed by consultation with experts and then tested on patients to confirm the clarity and feasibility of administration. A total of 306 participants participated in the construct validity study. Construct validity was investigated using Mokken scale analysis and analyzing associations between scales. The agreement between each pair of the scales' scores was further examined. The Self-perceived Difficulty Scale consisted of 10 items, and the Ability Scale included 8 items (excluding both bladder and bowel control items). Items in each individual scale were unidimensional (H ≥ 0.5). The scores of the Self-perceived Difficulty and Ability Scales were highly correlated with those of the BI (rho = 0.78 and 0.90, respectively). The scores of the two BI-SS scales and BI were significantly different from each other (pscales assessed unique constructs. The BI-SS had overall good construct validity in patients with stroke. The BI-SS can be used as supplementary scales for the BI to comprehensively assess patients' ADL functions in order to identify patients' difficulties in performing ADL tasks, plan intervention strategies, and assess outcomes.

    Full Text Available Self-regulation is a key issue for teachers. Self-regulatory competencies help teachers maintain both their well-being and professional commitment. This is of particular importance when it comes to teaching in culturally diverse classrooms. However, this facet is generally neglected when Teacher Education supports pre- and inservice teachers in the development of their intercultural competencies. Against this background, the current paper deals with the development of three scales for the assessment of self-regulatory aspects of teachers' intercultural competence - the Teacher Cultural Diversity Flexibility Scale (TCDFS, the Teacher Cultural Diversity Emotional Regulation Scale (TCDERS, and the Teacher Cultural Diversity Tolerance for Ambiguity Scale (TCDTAS. Each scale was developed and validated in two forms: one referring to minority students in general, and one referring specifically to Roma students. The results indicate generally good reliabilities (αs from .74 to .91 and a unifactorial structure for each of the proposed scales. Both forms (general and the one for the Roma of the TCDFS and the TCDERS also demonstrated concurrent validity. An assessment based on these scales may better inform training interventions aiming to develop self-regulatory aspect of teachers' intercultural competence and to measure the outcomes and efficacy of such interventions. However, correlation analyses have also revealed some weaknesses of the TCDTAS. In the light of these results, further efforts should be directed at reanalysing the construct of self-regulation in dealing with diversity.

    Full Text Available Abstract Background Many children do not meet physical activity guidelines. Parents and friends are likely to influence children's physical activity but there is a shortage of measures that are able to capture these influences. Methods A new questionnaire with the following three scales was developed: 1 Parental influence on physical activity; 2 Motives for activity with friends scale; and 3 Physical activity and sedentary group normative values. Content for each scale was informed by qualitative work. One hundred and seventy three, 10-11 year old children completed the new questionnaire twice, one week apart. Participants also wore an accelerometer for 5 days and mean minutes of moderate to vigorous physical activity, light physical activity and sedentary time per day were obtained. Test-retest reliability of the items was calculated and Principal Component analysis of the scales performed and sub-scales produced. Alphas were calculated for main scales and sub-scales. Correlations were calculated among sub-scales. Correlations between each sub-scale and accelerometer physical activity variables were calculated for all participants and stratified by sex. Results The Parental influence scale yielded four factors which accounted for 67.5% of the variance in the items and had good (α > 0.7 internal consistency. The Motives for physical activity scale yielded four factors that accounted for 66.1% and had good internal consistency. The Physical activity norms scale yielded 4 factors that accounted for 67.4% of the variance, with good internal consistency for the sub-scales and alpha of .642 for the overall scale. Associations between the sub-scales and physical activity differed by sex. Although only 6 of the 11 sub-scales were significantly correlated with physical activity there were a number of associations that were positively correlated >0.15 indicating that these factors may contribute to the explanation of children's physical activity

    2017-11-01

    Full Text Available Safety attitude is of vital importance to accident prevention, and the high accident rate in the coal mining industry makes it urgent to undertake research on coal miners’ safety attitude. However, the current literature still lacks a valid and reliable safety attitude measurement scale for coal miners, which stands as a barrier against their safety attitude improvement. In this study, a scale is developed that can be used to measure coal miners’ safety attitude. The preliminary scale was based on an extended literature review. Empirical data were then collected from 725 coal miners using the preliminary scale. Both exploratory and confirmatory factor analyses were undertaken to validate and improve the scale. The final scale, which consists of 17 items, contains four dimensions: management safety commitment, team safety climate, fatalism and work pressure. Results show that this safety attitude scale can effectively measure the safety attitude of coal miners, showing high psychological measurement validity. This paper contributes to the occupational safety research by developing the factor structure and indicator system of coal miners’ safety attitude, thus providing more profound interpretation of this crucial construct in the safety research domain. The measurement scale serves as an important tool for safety attitude benchmarking among different coal mining enterprises and, thus, can boost the overall safety improvement of the whole industry. These findings can facilitate improvement of both theories and practices related to occupational safety attitude.

    To develop and validate brief scales to measure common emotional and behavioural problems among adolescents in the examination-oriented education system and collectivistic culture of China. Middle schools in Hunan province. 5442 middle school students aged 11-19 years were sampled. 4727 valid questionnaires were collected and used for validation of the scales. The final sample included 2408 boys and 2319 girls. The tools were assessed by the item response theory, classical test theory (reliability and construct validity) and differential item functioning. Four scales to measure anxiety, depression, study problem and sociality problem were established. Exploratory factor analysis showed that each scale had two solutions. Confirmatory factor analysis showed acceptable to good model fit for each scale. Internal consistency and test-retest reliability of all scales were above 0.7. Item response theory showed that all items had acceptable discrimination parameters and most items had appropriate difficulty parameters. 10 items demonstrated differential item functioning with respect to gender. Four brief scales were developed and validated among adolescents in middle schools of China. The scales have good psychometric properties with minor differential item functioning. They can be used in middle school settings, and will help school officials to assess the students' emotional/behavioural problems. Published by the BMJ Publishing Group Limited.

    A bench scale cell culture model representative of manufacturing scale (2,000 L) was developed based on oxygen mass transfer principles, for a CHO-based process producing a recombinant human protein. Cell culture performance differences across scales are characterized most often by sub-optimal performance in manufacturing scale bioreactors. By contrast in this study, reduced growth rates were observed at bench scale during the initial model development. Bioreactor models based on power per unit volume (P/V), volumetric mass transfer coefficient (kL a), and oxygen transfer rate (OTR) were evaluated to address this scale performance difference. Lower viable cell densities observed for the P/V model were attributed to higher sparge rates and reduced oxygen mass transfer efficiency (kL a) of the small scale hole spargers. Increasing the sparger kL a by decreasing the pore size resulted in a further decrease in growth at bench scale. Due to sensitivity of the cell line to gas sparge rate and bubble size that was revealed by the P/V and kL a models, an OTR model based on oxygen enrichment and increased P/V was selected that generated endpoint sparge rates representative of 2,000 L scale. This final bench scale model generated similar growth rates as manufacturing. In order to take into account other routinely monitored process parameters besides growth, a multivariate statistical approach was applied to demonstrate validity of the small scale model. After the model was selected based on univariate and multivariate analysis, product quality was generated and verified to fall within the 95% confidence limit of the multivariate model. © 2014 Wiley Periodicals, Inc.

    Purpose: To develop and validate a psychometric scale for assessing image quality perception for chest X-ray images. Methods: Bandura's theory was used to guide scale development. A review of the literature was undertaken to identify items/factors which could be used to evaluate image quality using a perceptual approach. A draft scale was then created (22 items) and presented to a focus group (student and qualified radiographers). Within the focus group the draft scale was discussed and modified. A series of seven postero-anterior chest images were generated using a phantom with a range of image qualities. Image quality perception was confirmed for the seven images using signal-to-noise ratio (SNR 17.2–36.5). Participants (student and qualified radiographers and radiology trainees) were then invited to independently score each of the seven images using the draft image quality perception scale. Cronbach alpha was used to test interval reliability. Results: Fifty three participants used the scale to grade image quality perception on each of the seven images. Aggregated mean scale score increased with increasing SNR from 42.1 to 87.7 (r = 0.98, P < 0.001). For each of the 22 individual scale items there was clear differentiation of low, mid and high quality images. A Cronbach alpha coefficient of >0.7 was obtained across each of the seven images. Conclusion: This study represents the first development of a chest image quality perception scale based on Bandura's theory. There was excellent correlation between the image quality perception scores derived using the scale and the SNR. Further research will involve a more detailed item and factor analysis

    This study aimed to develop and evaluate scales reflecting potentially modifiable social cognitive theory-based risk indicators associated with homeless populations' oral health. The scales are referred to as the social cognitive theory risk scales in an oral health context (SCTOH) and are referred to as SCTOH(SE), SCTOH(K) and SCTOH(F), respectively. The three SCTOH scales assess the key constructs of social cognitive theory: self-efficacy, knowledge and fatalism. The reliability and validity of the three scales were evaluated in a convenience sample of 248 homeless participants (age range 17-78 years, 79% male) located in a metropolitan setting in Australia. The scales were supported by exploratory factor analysis and established three distinct and internally consistent domains of social cognition: oral health-related self-efficacy, oral health-related knowledge and oral health-related fatalism, with Cronbach's alphas of 0.95, 0.85 and Spearman's-Brown ρ of 0.69. Concurrent ability was confirmed by each SCTOH scale's association with oral health status in the expected directions. The three SCTOH scales appear to be internally valid and reliable. If confirmed by further research, these scales could potentially be used for tailored educational and cognitive-behavioural interventions to reduce oral health inequalities among homeless and other vulnerable populations. © 2015 Public Health Association of Australia.

    Valid instruments of parenting practices related to children's physical activity (PA) are essential to understand how parents affect preschoolers' PA. This study developed and validated a questionnaire of PA-related parenting practices for Chinese-speaking parents of preschoolers in Hong Kong. Parents (n = 394) completed a questionnaire developed using findings from formative qualitative research and literature searches. Test-retest reliability was determined on a subsample (n = 61). Factorial validity was assessed using confirmatory factor analysis. Subscale internal consistency was determined. The scale of parenting practices encouraging PA comprised 2 latent factors: Modeling, structure and participatory engagement in PA (23 items), and Provision of appropriate places for child's PA (4 items). The scale of parenting practices discouraging PA scale encompassed 4 latent factors: Safety concern/overprotection (6 items), Psychological/behavioral control (5 items), Promoting inactivity (4 items), and Promoting screen time (2 items). Test-retest reliabilities were moderate to excellent (0.58 to 0.82), and internal subscale reliabilities were acceptable (0.63 to 0.89). We developed a theory-based questionnaire for assessing PA-related parenting practices among Chinese-speaking parents of Hong Kong preschoolers. While some items were context and culture specific, many were similar to those previously found in other populations, indicating a degree of construct generalizability across cultures.

    HIV/AIDS stigma continues to be an obstacle for primary and secondary HIV prevention. Its consequences for the lives of people living with the disease have been well documented and continue to be of great concern for health care providers and researchers in the field. These consequences are worsened when such stigma emanates from health professionals, as this can limit access to services. One of the main obstacles for HIV/AIDS stigma research in Puerto Rico is the absence of quantitative measures to assess HIV/AIDS stigma manifestations among health professionals. In light of this gap in the scientific literature, the main objective of this study was to develop and test the psychometric properties of a culturally appropriate HIV/AIDS Stigma Scale for Puerto Rican health care providers and to develop a reduced form of the scale suitable for use in time-limited clinical settings. The developed measure was based on previous qualitative evidence gathered from Puerto Rican health professionals (Varas-Diaz, Serrano-Garcia, & Toro-Alfonso, 2005) and administered to a sample of 421 health professionals in training. The scale addresses 12 HIV/AIDS stigma dimensions. In quantitative analyses 11 of these dimensions demonstrated satisfactory validity and reliability. These dimensions in turn were subcomponents of a higher-order general stigma factor. Implications and limitations of these findings are discussed.

    One of the major challenges that developing organs face is scaling, that is, the adjustment of physical proportions during the massive increase in size. Although organ scaling is fundamental for development and function, little is known about the mechanisms that regulate it. Bone superstructures are projections that typically serve for tendon and ligament insertion or articulation and, therefore, their position along the bone is crucial for musculoskeletal functionality. As bones are rigid structures that elongate only from their ends, it is unclear how superstructure positions are regulated during growth to end up in the right locations. Here, we document the process of longitudinal scaling in developing mouse long bones and uncover the mechanism that regulates it. To that end, we performed a computational analysis of hundreds of three-dimensional micro-CT images, using a newly developed method for recovering the morphogenetic sequence of developing bones. Strikingly, analysis revealed that the relative position of all superstructures along the bone is highly preserved during more than a 5-fold increase in length, indicating isometric scaling. It has been suggested that during development, bone superstructures are continuously reconstructed and relocated along the shaft, a process known as drift. Surprisingly, our results showed that most superstructures did not drift at all. Instead, we identified a novel mechanism for bone scaling, whereby each bone exhibits a specific and unique balance between proximal and distal growth rates, which accurately maintains the relative position of its superstructures. Moreover, we show mathematically that this mechanism minimizes the cumulative drift of all superstructures, thereby optimizing the scaling process. Our study reveals a general mechanism for the scaling of developing bones. More broadly, these findings suggest an evolutionary mechanism that facilitates variability in bone morphology by controlling the activity of

    The objective of this study was to develop and test a Partnership Development Process Assessment (PDPA) scale for content and construct validity and internal consistency reliability. This is needed to document and evaluate community health partnership development processes between public health nurses and community-based organizations in Japan. The study was conducted in three phases. Ten semi-structured interviews were conducted to generate items for a new scale. Thirty items were generated and reviewed by an expert panel for content validity and item refinement. A national postal survey of public health nurses was conducted to determine the scale's internal structure, evaluate its reliability, and explore its construct and criterion validity. Validity and reliability testing of the PDPA scale using a content validity index and analysis of correlations with an existing scale were performed. Twenty-six items were selected and grouped into four factors: activities to share roles to manage community health issues, platform activities to support partnerships, activities to evaluate partnership practices, and activities to share information regarding community health issues. After factor analysis, 23 items were retained. The PDPA scale is a valid and reliable instrument for public health nurses to assess partnership development activities. © 2015 Wiley Periodicals, Inc.

    Efficient development of highly functional porous materials, used as catalysts in the automobile industry, demands a meticulous knowledge of the nano-scale interface at the electronic and atomistic scale. However, it is often difficult to correlate the microscopic interfacial interactions with macroscopic characteristics of the materials; for instance, the interaction between a precious metal and its support oxide with long-term sintering properties of the catalyst. Multi-scale computational chemistry approaches can contribute to bridge the gap between micro- and macroscopic characteristics of these materials; however this type of multi-scale simulations has been difficult to apply especially to porous materials. To overcome this problem, we have developed a novel mesoscopic approach based on a porous structure simulator. This simulator can construct automatically irregular porous structures on a computer, enabling simulations with complex meso-scale structures. Moreover, in this work we have developed a new method to simulate long-term sintering properties of metal particles on porous catalysts. Finally, we have applied the method to the simulation of sintering properties of Pt on alumina support. This newly developed method has enabled us to propose a multi-scale simulation approach for porous catalysts

    To apply a Mokken Scale Procedure in developing a hierarchical cross-national scale to measure xenophobia, a pool of 30 xenophobia-related items was collected from several sources and modified using established unidimensional criteria. The survey was administered to 608 undergraduate students in the USA, 193 undergraduate students in The Netherlands, and 303 undergraduate students in Norway. 14 items measuring perceived threat or fear and meeting the criteria of the Stereotype Content Model were selected for further analysis. A separate item analysis and, subsequently, Mokken Scale Procedure yielded a cumulative scale with the same five items for each of the three samples. The items and the total scale met criteria for homogeneity in all samples with H > .40.

    Pediatric neuro-oncology researchers face methodological challenges associated with quantifying the influence of tumor and treatment-related risk factors on child outcomes. The Neurological Predictor Scale was developed to serve as a cumulative index of a child's exposure to risk factors. The clinical utility of the Neurological Predictor Scale was explored in a sample of 25 children with heterogeneous brain tumors. Consistent with expectation, a series of regression analyses demonstrated that the Neurological Predictor Scale significantly predicted composite intellectual functioning (r(2) = 0.21, p Scale accounted for a significant amount of the variance in child intellectual functioning above and beyond individually examined variables. The Neurological Predictor Scale can be used to quickly quantify the cumulative risk factors associated with pediatric brain tumor diagnoses.

    The purpose of this study is to develop a smoking rationalization scale for Chinese male smokers. A total of 35 focus groups and 19 one-on-one interviews were conducted to collect items of the scale. Exploratory factor analyses and confirmatory factor analyses were conducted to identify the underlying structure of the scale. Results found a 26-item scale within six dimensions (smoking functional beliefs, risk generalization beliefs, social acceptability beliefs, safe smoking beliefs, self-exempting beliefs, and quitting is harmful beliefs). The scale showed acceptable validity and reliability. Results highlight that smoking rationalization is common among Chinese male smokers, and some beliefs of smoking rationalization seem to be peculiar to China.

    Children aged 3 to 12 years (n=184) with typical development, deafness, autism or Asperger Syndrome took a series of theory-of-mind (ToM) tasks to confirm and extend previous developmental scaling evidence. A new sarcasm task, in the format of Wellman and Liu’s (2004) 5-step ToM scale, added a statistically reliable sixth step to the scale for all diagnostic groups. A key previous finding, divergence in task sequencing for children with autism, was confirmed. Comparisons among diagnostic groups, controlling age and language ability, showed that typical developers mastered the six ToM steps ahead of each of the three disabled groups, with implications for ToM theories. The final (sarcasm) task challenged even nondisabled 9-year-olds, demonstrating the new scale’s sensitivity to post-preschool ToM growth. PMID:22304467

    A scale did not exist for measuring the capability or self-care agency of lowering salt consumption in older adults with hypertension. Therefore, our objectives were to develop and validate the Dietary Sodium Reduction Self-Care Agency Scale (DSR-SCA Scale). A 24-item scale was developed and tested in 242 older adults with hypertension. Exploratory factor analysis using principal components extraction, Rasch analysis, and internal consistency reliability were used to evaluate the DSR-SCA Scale. Principal components extraction with Promax rotation was used. An 11-item DSR-SCA Scale with three factor loadings, which measure proficiency, persuasiveness, and resourcefulness, was finalized after it was found to meet the criteria of a minimal factor loading of 0.40, with eigenvalues of 2.20, 1.73, and 1.64, respectively. The Kaiser-Meyer-Olkin was 0.80, and Bartlett's test was significant, χ(2) (df = 55) 403.71, p measures accounted for 51% of the total variance. Item infit and outfit mean square ranged from 0.88 to 1.18 and the infit and outfit standardized mean square was -1.8 to 1.7. The 11-item scale demonstrated internal consistency with a Cronbach's alpha coefficient of 0.73 for the total scale. The results showed that the DSR-SCA Scale consisted of three factors that have adequate construct validity and reliability to measure power components and enabling capability related to Orem's self-care theory. This scale is brief, easy-to-complete, and useful for measuring salt reduction self-care agency in older adults with hypertension Copyright 2013, SLACK Incorporated.

    2014-01-01

    ‘Micro-scaled Products Development via Microforming’ presents state-of-the-art research on microforming processes, and focuses on the development of micro-scaled metallic parts via microforming processes. Microforming refers to the fabrication of microparts via micro-scaled plastic deformation and  presents a promising micromanufacturing process. When compared to other  micromanufacturing processes, microforming offers advantages such as high productivity and good mechanical properties of the deformed microparts. This book provides extensive and informative illustrations, tables and photos in order to convey this information clearly and directly to readers. Although the knowledge of macroforming processes is abundant and widely used in industry, microparts cannot be developed by leveraging existing knowledge of macroforming because the size effect presents a barrier to this knowledge transfer. Therefore systematic knowledge of microforming needs to be developed. In tandem with product miniaturization, t...

    The airline industry relies on the implementation of Safety Management System (SMS) to integrate safety policies and augment safety performance at both organizational and individual levels. Although there are various degrees of SMS implementation in practice, a comprehensive scale measuring the essential dimensions of SMS is still lacking. This paper thus aims to develop an SMS measurement scale from the perspective of aviation experts and airline managers to evaluate the performance of company's safety management system, by adopting Schwab's (1980) three-stage scale development procedure. The results reveal a five-factor structure consisting of 23 items. The five factors include documentation and commands, safety promotion and training, executive management commitment, emergency preparedness and response plan and safety management policy. The implications of this SMS evaluation scale for practitioners and future research are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.
