Dures, Emma; Hewlett, Sarah

2012-09-01

Patients with rheumatic disease must adjust psychosocially and behaviourally in order to manage the impact of symptoms and treatment on their daily lives, and the emotional consequences of the disease. However, patients can improve their well-being by taking a proactive role in self-management, for example by using coping strategies. Support for patient self-management from clinical teams usually comprises information and advice on disease management; however, this largely didactic approach often focuses on the biomedical aspects of rheumatic disease, without addressing how these aspects interact with psychosocial factors to influence health behaviours and thus outcomes. A cognitive-behavioural approach based on the biopsychosocial model of rheumatic disease can facilitate the identification of effective self-management strategies through collaboration between patients and clinicians. Most patients do not require intense cognitive-behavioural therapy from a clinical psychologist; rather, basic cognitive-behavioural techniques and tools could be used by rheumatology clinical teams to expand and enhance the support already offered to patients.

With the increasing availability of gambling throughout North America, there is interest in developing more effective treatments. This study compares the effectiveness of two brief outpatient treatments for problem gambling: eight sessions of Cognitive-Behavioral Therapy (n = 65) and eight sessions of a twelve-step treatment-oriented approach based on the first five steps of Gamblers Anonymous (n = 61). There were no baseline group differences on gambling-relevant variables. Twelve months post-treatment showed no group differences on key gambling variables (eg, frequency, abstinence rates, money wagered) in an analysis of completers. Participants who attended more sessions and chose an initial abstinent treatment goal appeared to achieve better outcomes.

Narrative Enhancement and Cognitive Therapy: A New Group-Based Treatment for Internalized Stigma among Persons with Severe Mental Illness

Science.gov (United States)

Yanos, Philip T.; Roe, David; Lysaker, Paul H.

2011-01-01

Internalized stigma has been suggested to play a major role in negative changes in identity in severe mental illness. Evidence suggests that roughly one-third of people with severe mental illness show elevated internalized stigma and that it is linked to compromised outcomes in both subjective and objective aspects of recovery. Despite substantial evidence for the impact of internalized stigma, few efforts have been made to develop professionally-led treatment to address this issue. In this article, we discuss our development of a new, group-based approach to the treatment of internalized stigma which we have termed “narrative enhancement and cognitive therapy” (NECT). We describe the treatment approach and offer an illustration of it by way of a case vignette. PMID:21985260

Barriers to implementing evidence-based practices in addiction treatment programs: comparing staff reports on Motivational Interviewing, Adolescent Community Reinforcement Approach, Assertive Community Treatment, and Cognitive-behavioral Therapy.

This qualitative study explored barriers to implementing evidence-based practices (EBPs) in community-based addiction treatment organizations (CBOs) by comparing staff descriptions of barriers for four EBPs: Motivational Interviewing (MI), Adolescent Community Reinforcement Approach (A-CRA), Assertive Community Treatment (ACT), and Cognitive-behavioral Therapy (CBT). The CBOs received CSAT/SAMHSA funding from 2003 to 2008 to deliver services using EBPs. Phone interview responses from 172 CBO staff directly involved in EBP implementation were analyzed using content analysis, a method for making inferences and developing themes from the systematic review of participant narratives (Berelson, 1952). Staff described different types of barriers to implementing each EBP. For MI, the majority of barriers involved staff resistance or organizational setting. For A-CRA, the majority of barriers involved specific characteristics of the EBP or client resistance. For CBT, the majority of barriers were associated with client resistance, and for ACT, the majority of barriers were associated with resources. EBP designers, policy makers who support EBP dissemination and funders should include explicit strategies to address such barriers. Addiction programs proposing to use specific EBPs must consider whether their programs have the organizational capacity and community capacity to meet the demands of the EBP selected.

[Treatment of substance dependence by a bio-cognitive model based on behavioral pharmacology].

Hori, Toru; Komiyama, Tokutaro; Harada, Seiichi; Matsumoto, Takenori

2005-01-01

We have introduced cognitive behavior therapy (CBT) into the treatment of substance dependence patients, which involves disease education and focused group therapy to obtain insight into the taking behavior and to establish concrete countermeasures to prevent relapse. We have created a bio-cognitive model based on biological aspects to explain the pathology of substance dependence. 'Dependence' is a term in behavioral pharmacology defined as reinforced drug seeking and taking behavior. Changes in taking behavior are thought to occur due to the repetition of the reinforcement action of psychoactive substances in the reward system of the brain. Therefore, when intake desire is strong, it is hard for patients to control themselves, and there is a feature of difficulties considering the process of thinking in CBT. In other words, when craving becomes strong, a chain of behavior happens spontaneously, without schema, involving automatic thoughts. We think that the improvement of protracted withdrawal syndrome (PWS) and entire frontal lobe function are important in learning to discern distortion of cognition. When PWS is improved, a conflict is easy to bring about in the process of drug seeking and taking behavior. And, it is easy to execute avoidance plans (coping skills) which are established to cope with craving in advance. We think that a goal for treatment is to discern drug seeking and taking behavior with natural emotion. The recovery of PWS and frontal lobe dysfunction takes a long time with a serious dependence, so we must perform repetition of CBT. As the treatment introduction of involuntary admission cases is adequate or cases of 1 to 3 months of admission treatment based on voluntary admission are hard to treat, treatment to obtain insights into patients while carrying out repeated CBT using a bio-cognitive model and to improve PWS could be a possibility as one treatment for the pathology of diversified substance dependence.

More recent theories of addiction suggest that neurocognitive mechanisms, such as attentional processing, cognitive control, and reward processing play a key role in the development or maintenance of addiction. Ultimately, the addiction (with or without substances) is based on the alteration of brain decision-making processes. The neurosciences, particularly those responsible for behavior modification, must take into account the neurobiological processes underlying the observable behavior. Treatments of addiction usually do not take into account these findings, which may be at the base of the low retention rates and high dropout rates of addicted patients. Considered as an alteration of brain functioning, addiction could be addressed successfully through cognitive rehabilitation treatments used in other clinical pathologies such as brain damage or schizophrenia. Although there are few studies, it is suggest that intervention to improve patients' cognitive functioning can improve the efficiency of well-established cognitive-behavioral therapies, such as relapse prevention. This paper reviews the available evidence on cognitive rehabilitation in treating addiction as well as in other pathologies, in order to formulate interventions that may be included in comprehensive rehabilitation programs for people with addictive disorders.

Cognitive Function as a Transdiagnostic Treatment Target in Stimulant Use Disorders.

Stimulant use disorder is an important public health problem, with an estimated 2.1 million current users in the United States alone. No pharmacological treatments are approved by the U.S. Food and Drug Administration for stimulant use disorder and behavioral treatments have variable efficacy and limited availability. Most individuals with stimulant use disorder have other comorbidities, most with overlapping symptoms and cognitive impairments. The goal of this article is to present a rationale for cognition as a treatment target in stimulant use disorder and to outline potential treatment approaches. Rates of lifetime comorbid psychiatric disorders among people with stimulant use disorders are estimated at 65% to 73%, with the most common being mood disorders (13% to 64%) and anxiety disorders (21% to 50%), as well as non-substance-induced psychotic disorders (addictive behavior, but the dual process model particularly highlights the relevance of cognitive impairments and biases to the development and maintenance of addiction. This model explains addictive behavior as a balance between automatic processes and executive control, which in turn are related to individual (genetics, comorbid disorders, psychosocial factors) and other (craving, triggers, drug use) factors. Certain cognitive impairments, such as attentional bias and approach bias, are most relevant to automatic processes, while sustained attention, response inhibition, and working memory are primarily related to executive control. These cognitive impairments and biases are also common in disorders frequently comorbid with stimulant use disorder and predict poor treatment retention and clinical outcomes. As such, they may serve as feasible transdiagnostic treatment targets. There are promising pharmacological, cognitive, and behavioral approaches that aim to enhance cognitive function. Pharmacotherapies target cognitive impairments associated with executive control and include cholinesterase inhibitors

Going up in Smoke? A Review of nAChRs-based Treatment Strategies for Improving Cognition in Schizophrenia

2015-01-01

Cognitive impairment is known to be a core deficit in schizophrenia. Existing treatments for schizophrenia have limited efficacy against cognitive impairment. The ubiquitous use of nicotine in this population is thought to reflect an attempt by patients to self-medicate certain symptoms associated with the illness. Concurrently there is evidence that nicotinic receptors that have lower affinity for nicotine are more important in cognition. Therefore, a number of medications that target nicotinic acetylcholine receptors (nAChRs) have been tested or are in development. In this article we summarize the clinical evidence of nAChRs dysfunction in schizophrenia and review clinical studies testing either nicotine or nicotinic medications for the treatment of cognitive impairment in schizophrenia. Some evidence suggests beneficial effects of nAChRs based treatments for the attentional deficits associated with schizophrenia. Standardized cognitive test batteries have failed to capture consistent improvements from drugs acting at nAChRs. However, more proximal measures of brain function, such as ERPs relevant to information processing impairments in schizophrenia, have shown some benefit. Further work is necessary to conclude that nAChRs based treatments are of clinical utility in the treatment of cognitive deficits of schizophrenia. PMID:24345265

2014-01-01

A number of cognitive interventions have been developed to enhance cognitive functioning in the growing population of the elderly. We describe the Mindfulness-Based Cognitive Approach for Seniors (MBCAS), a new training program designed especially for seniors. It was conceived in the context of self-development for seniors who wish to enhance their relationship with their inner and outer selves in order to navigate their aging process more easily and fluently. Physical and psychosocial problems related to aging, as well as some temporal issues, were taken into account in developing this program. Unlike clinically oriented mindfulness-based programs, which are generally delivered during an 8-week period, the MBCAS training program is presented over a period of 8 months. The main objectives of this program are to teach seniors to observe current experiences with nonjudgmental awareness, to identify automatic behaviors or reactions to current experiences that are potentially nonadaptive, and to enhance and reinforce positive coping with typical difficulties that they face in their daily lives. Details of the program development and initial implementation are presented, with suggestions for evaluating the program's effectiveness.

2017-01-01

The study aim was to test whether a 12-week publically rebated group programme, based upon Steketee and Frost's Cognitive Behavioural Therapy-based hoarding treatment, would be efficacious in a community-based setting. Over a 3-year period, 77 participants with clinically significant hoarding were recruited into 12 group programmes. All completed treatment; however, as this was a community-based naturalistic study, only 41 completed the post-treatment assessment. Treatment included psychoeducation about hoarding, skills training for organization and decision making, direct in-session exposure to sorting and discarding, and cognitive and behavioural techniques to support out-of-session sorting and discarding, and nonacquiring. Self-report measures used to assess treatment effect were the Savings Inventory-Revised (SI-R), Savings Cognition Inventory, and the Depression, Anxiety and Stress Scales. Pre-post analyses indicated that after 12 weeks of treatment, hoarding symptoms as measured on the SI-R had reduced significantly, with large effect sizes reported in total and across all subscales. Moderate effect sizes were also reported for hoarding-related beliefs (emotional attachment and responsibility) and depressive symptoms. Of the 41 participants who completed post-treatment questionnaires, 14 (34%) were conservatively calculated to have clinically significant change, which is considerable given the brevity of the programme judged against the typical length of the disorder. The main limitation of the study was the moderate assessment completion rate, given its naturalistic setting. This study demonstrated that a 12-week group treatment for hoarding disorders was effective in reducing hoarding and depressive symptoms in an Australian clinical cohort and provides evidence for use of this treatment approach in a community setting.

Therapy decision making and support in medicine deals with uncertainty and needs to take into account the patient's clinical parameters, the context of illness and the medical knowledge of the physician and guidelines to recommend a treatment therapy. This research study is focused on the formalization of medical knowledge using a cognitive process, called Fuzzy Cognitive Maps (FCMs) and semantic web approach. The FCM technique is capable of dealing with situations including uncertain descriptions using similar procedure such as human reasoning does. Thus, it was selected for the case of modeling and knowledge integration of clinical practice guidelines. The semantic web tools were established to implement the FCM approach. The knowledge base was constructed from the clinical guidelines as the form of if-then fuzzy rules. These fuzzy rules were transferred to FCM modeling technique and, through the semantic web tools, the whole formalization was accomplished. The problem of urinary tract infection (UTI) in adult community was examined for the proposed approach. Forty-seven clinical concepts and eight therapy concepts were identified for the antibiotic treatment therapy problem of UTIs. A preliminary pilot-evaluation study with 55 patient cases showed interesting findings; 91% of the antibiotic treatments proposed by the implemented approach were in fully agreement with the guidelines and physicians' opinions. The results have shown that the suggested approach formalizes medical knowledge efficiently and gives a front-end decision on antibiotics' suggestion for cystitis. Concluding, modeling medical knowledge/therapeutic guidelines using cognitive methods and web semantic tools is both reliable and useful. Copyright © 2011 Elsevier Inc. All rights reserved.

Beyond Thiamine: Treatment for Cognitive Impairment in Korsakoff's Syndrome.

2018-03-27

Wernicke's encephalopathy is a condition whose treatment many consultation-liaison psychiatrists know quite well. Less clear, however, is the treatment of its dementia disorder descendent, the Korsakoff's syndrome (KS). This article seeks to review treatment options and provide recommendations for consultation-liaison psychiatrists treating cognitive impairment in KS. In this nonsystematic review, we reviewed PubMed, CINAHL Plus, and Google Scholar for published reports and studies regarding treatment of KS. The literature revealed case reports and placebo-controlled trials of various medications for treatment of KS, though the samples sizes were small and were mostly case reports. There is more attention devoted toward medications used in other dementia disorders, such as donepezil and memantine. The literature revealed more studies around behavioral interventions recommended for treatment of memory impairment in KS and they focused on cognitive remediation and environmental adaptation, such as the use of PDAs or alarms. There is no single, well-studied intervention proven effective as a primary treatment for cognitive impairment in KS. An approach of using environmental modifications in a well-structured living environment, combined with various cognitive interventions, such as pictorial associations, and perhaps a trial of donepezil or memantine, likely represents the best strategy for treating long-term cognitive impairment in KS.

Key, Brenda L; Rowa, Karen; Bieling, Peter; McCabe, Randi; Pawluk, Elizabeth J

2017-09-01

A significant number of obsessive-compulsive disorder (OCD) patients continue to experience symptoms that interfere with their functioning following cognitive behavioural therapy (CBT). Providing an additional augmentation treatment following CBT could help reduce these residual symptoms. Mindfulness interventions that facilitate less reactivity to thoughts and feelings may be helpful for patients suffering from residual OCD symptoms. The purpose of the current randomized waitlist control trial was to evaluate the feasibility and impact of providing an 8-week mindfulness-based cognitive therapy (MBCT) intervention following completion of a CBT intervention to OCD patients who continued to suffer from significant symptoms. Results indicated that compared to the waitlist control group, MBCT participants reported decreases in OCD symptoms (d = 1.38), depression symptoms (d = 1.25), anxiety symptoms (d = 1.02), and obsessive beliefs (d = 1.20) along with increases in self-compassion (d = 0.77) and mindfulness skills (d = 0.77). Additionally, participants reported high levels of satisfaction with the MBCT intervention. The results suggest that the use of MBCT for OCD as an augmentation therapy is acceptable to patients who continue to suffer from OCD symptoms after completing CBT and provides some additional relief from residual symptoms. Mindfulness interventions teach skills that facilitate disengaging from cognitive routines and accepting internal experience, and these skills may be valuable in treating obsessive-compulsive disorder (OCD), as individuals describe getting "stuck" in repetitive thoughts and consequent rituals. The results of this study suggest that teaching mindfulness skills using an 8-week mindfulness-based cognitive therapy (MBCT) intervention provides an added benefit (decreases in OCD, depression, and anxiety symptoms) for patients with OCD who have completed a cognitive behavioural therapy intervention and continued to suffer from

2014-01-01

Many studies have investigated the impact of pediatric Cognitive Rehabilitation Therapy (CRT) upon intellectual functioning after traumatic brain injury; however, relatively few have identified efficacious treatment in a school setting. The purpose is to present a variety of CRT strategies that would be useful to a teacher or therapist working with students who are learning disabled or who have who have had a traumatic brain injury (TBI). This article investigates the particular challenges in learning which result from impaired cognition, and suggests techniques for improving memory and executive functioning. Students who are learning disabled or who have TBI face social and emotional issues that impact their learning. Special therapeutic interventions are necessary to assist with orienting to their setting, integrating with peers, and coping with distressing emotions. Students with TBI can adapt and flourish in a school based setting provided that therapies and learned strategies are targeted to their specific needs.

Group-based trajectory modeling is particularly important to identify subgroups of patients with pathological cognitive changes after cancer treatment. To date, only one study has explored cognitive trajectories in older patients with cancer. The present article describes objective cognitive changes before to after adjuvant treatment in older adults with early-stage breast cancer (EBC) after adjuvant treatment compared with healthy controls. Participants were patients ≥65 years of age with newly diagnosed EBC and healthy controls (age-, sex-, and education-matched). The pretreatment assessment was conducted before adjuvant therapy, and the post-treatment assessment after the end of the first adjuvant treatment. Objective cognitive changes before to after treatment were evaluated based on the Reliable Change Index for cognitive decline accounting for cognitive impairment status. The sample consisted of women newly diagnosed with EBC ( n  = 118) and healthy controls ( n  = 62). Five patterns of changes before to after treatment were identified based on the presence of cognitive decline and cognitive impairment. The distribution of these five change patterns was statistically significant ( p  = .0001). Thirty-six percent of patients had phase shift changes, 31% without initial objective cognitive impairment developed impairment, 15% had a normal aging, 12% had a nonpathological decline, and 6% experienced accelerated cognitive decline. This study described for the first time objective cognitive changes before to after treatment of older adults with EBC immediately after the end of adjuvant treatment. A longer-term remote follow-up of adjuvant treatment is needed to better understand the cognitive trajectories of older patients with EBC. The Oncologist IMPLICATIONS FOR PRACTICE: After the end of adjuvant treatment, 31% of older adults with early-stage breast cancer without initial objective cognitive impairment developed impairment, and 6% experienced

Higher scores on the MFS were related to increases in reaction time during our mobile variant of the PVT. Conclusions The results show that the PVT mobile cognitive test developed for this study could be used as a valid and reliable method for measuring cognitive fatigue in situ. This test would remove the subjectivity associated with established self-assessment approaches and the need for assessments to be performed in a medical setting. Based on our findings, future work could explore delivering a small set of tests with increased duration to further improve measurement reliability. Moreover, as the smartphone assessment tool can be used as part of everyday life, additional sources of data relating to physiological, psychological, and environmental context could be included within the analysis to improve the nature and precision of the assessment process.

A Cognitive-pragmatic Approach to Puns

Directory of Open Access Journals (Sweden)

Jin Qiu

2013-05-01

Full Text Available The present paper is intended to provide a unified account for the interpretation of puns from a cognitive-pragmatic perspective. In recent years a few scholars have delved into the processing mechanism of puns, but none of them has demonstrably elucidated the cognitive psychological foundation of puns and the development of our cognitive strategy for pun interpretation. Through careful analyses, the present paper proves that the logic of taxonomy is the cognitive psychological foundation of puns and shows that a cognitive approach incorporating the notion of the impartment and inheritance of connotation and denotation (IICD for short can be successfully applied to the analyses of puns. Based on this notion, we propose a four-step hypothesis for the interpretation of puns. It is demonstrated that this hypothesis can effectively elucidate the interpretation of puns, and meanwhile, unfold a picture of addressees’ mental progress.

The cognitive approach to entrepreneurship is a response to the limitations of the trait approach. Its aim is to explain entrepreneurial behavior through cognitions. The main body of research has studied cognitive elements such as scripts, self-efficacy, cognitive styles and heuristics. Understanding entrepreneurial cognition represents a potential and productive field of research that, to date, has received little attention. In this article, we review and highlight the most important contributions of Cognitive Psychology to the field of entrepreneurship; we point out some of the limitations and suggest new avenues of enquiry.

The purpose of this study was to compare the communication effectiveness of a spiritually-based approach to breast cancer early detection education with a secular approach, among African American women, by conducting a cognitive response analysis. A total of 108 women from six Alabama churches were randomly assigned by church to receive a spiritually-based or secular educational booklet discussing breast cancer early detection. Based on the Elaboration Likelihood Model (Petty & Cacioppo, 1981), after reading the booklets participants were asked to complete a thought-listing task writing down any thoughts they experienced and rating them as positive, negative, or neutral. Two independent coders then used five dimensions to code participants thoughts. Compared with the secular booklet, the spiritually-based booklet resulted in significantly more thoughts involving personal connection, self-assessment, and spiritually-based responses. These results suggest that a spiritually-based approach to breast cancer awareness may be more effective than the secular because it caused women to more actively process the message, stimulating central route processing. The incorporation of spiritually-based content into church-based breast cancer education could be a promising health communication approach for African American women. PMID:18443989

Binge-eating disorder (BED) is a prevalent health condition associated with obesity. Few people with BED receive appropriate treatment. Personal barriers include shame, fear of stigma, geographic distance to mental health services, and long wait-lists. The aims of this study were to examine the efficacy of an Internet-based cognitive-behavioral intervention for adults with threshold BED (DSM-IV) and to examine the stability of treatment effects over 12months. Participants were randomly assigned to a 16-week Internet-based cognitive-behavioral intervention (n=69) or a wait-list condition (n=70). Binge-eating frequency and eating disorder psychopathology were measured with the Eating Disorder Examination-Questionnaire and the Eating Disorder Examination administered over the telephone. Additionally, body weight and body mass index, depression, and anxiety were assessed before and immediately after treatment. Three-, 6-, and 12-month follow-up data were recorded in the treatment group. Immediately after the treatment the number of binge-eating episodes showed significant improvement (d=1.02, between group) in the treatment group relative to the wait-list condition. The treatment group had also significantly reduced symptoms of all eating psychopathology outcomes relative to the wait-list condition (0.82≤d≤1.11). In the treatment group significant improvement was still observed for all measures 1year after the intervention relative to pretreatment levels. The Internet-based intervention proved to be efficacious, significantly reducing the number of binge-eating episodes and eating disorder pathology long term. Low-threshold e-health interventions should be further evaluated to improve treatment access for patients suffering from BED. Copyright © 2016. Published by Elsevier Ltd.

Brief, cost-contained, and effective psychiatric treatments benefit patients and public health. This naturalistic pilot study examined the effectiveness of a 2-week, cognitive-behavioral therapy (CBT) oriented partial hospital program. Study participants were 57 patients with mood, anxiety, and/or personality disorders receiving treatment in a private psychiatric partial hospital (PH) setting. A flexible treatment model was used that adapts evidence-based CBT treatment interventions to the PH context with emphases on psychoeducation and skills training. Participants completed self-report measures at admission and after 1 and 2 weeks, to assess stabilization and functional improvements, with added attention to the acquisition of cognitive and behavioral skills. The data were analyzed using repeated measures analyses of variance and correlation. Participants reported a decrease in symptoms and negative thought patterns, improved satisfaction with life, and acquisition and use of cognitive and behavioral skills. Skill acquisition was correlated with symptom reduction, reduced negative thought patterns, and improved satisfaction with life. Results of this pilot study suggest that a 2-week PH program can be effective for a heterogeneous patient population with mood, anxiety, and/or personality disorders. These findings are promising given the prevalence of treatments of such brief duration in private sector PH programs subject to the managed care marketplace. Future studies are planned to test this flexible PH treatment model, with particular attention to the effectiveness of the CBT approach for the treatment of different disorders and to whether effectiveness is sustained at follow-up. Further study should also examine whether skill acquisition is a mechanism of change for symptom reduction and functional improvements.

Physics students' approaches to learning and cognitive processes in solving physics problems

Bouchard, Josee

This study examined traditional instruction and problem-based learning (PBL) approaches to teaching and the extent to which they foster the development of desirable cognitive processes, including metacognition, critical thinking, physical intuition, and problem solving among undergraduate physics students. The study also examined students' approaches to learning and their perceived role as physics students. The research took place in the context of advanced courses of electromagnetism at a Canadian research university. The cognitive science, expertise, physics and science education, instructional psychology, and discourse processes literature provided the framework and background to conceptualize and structure this study. A within-stage mixed-model design was used and a number of instruments, including a survey, observation grids, and problem sets were developed specifically for this study. A special one-week long problem-based learning (PBL) intervention was also designed. Interviews with the instructors participating in the study provided complementary data. Findings include evidence that students in general engage in metacognitive processes in the organization of their personal study time. However, this potential, including the development of other cognitive processes, might not be stimulated as much as it could in the traditional lecture instructional context. The PBL approach was deemed as more empowering for the students. An unexpected finding came from the realisation that a simple exposure to a structured exercise of problem-solving (pre-test) was sufficient to produce superior planning and solving strategies on a second exposure (post-test) even for the students who had not been exposed to any special treatment. Maturation was ruled out as a potential threat to the validity of this finding. Another promising finding appears to be that the problem-based learning (PBL) intervention tends to foster the development of cognitive competencies, particularly

Cognitive behavioral therapy (CBT) is one of the main approaches in psychotherapy. It teaches the patient to examine the link between dysfunctional thoughts and maladaptive behaviors and to re- evaluate the cognitive biases involved in the maintenance of symptoms by using strategies such as guided discovery. CBT is constantly evolving in part to improve its' effectiveness and accessibility. Thus in the last decade, increasingly popular approaches based on mindfulness and acceptance have emerged. These therapies do not attempt to modify cognitions even when they are biased and dysfunctional but rather seek a change in the relationship between the individual and the symptoms. This article aims to present the historical context that has allowed the emergence of this trend, the points of convergence and divergence with traditional CBT as well as a brief presentation of the different therapies based on mindfulness meditation and acceptance. Hayes (2004) described three successive waves in behavior therapy, each characterized by "dominant assumptions, methods and goals": traditional behavior therapy, cognitive therapy and therapies based on mindfulness meditation and acceptance. The latter consider that human suffering occurs when the individual lives a restricted life in order avoid pain and immediate discomfort to the detriment of his global wellbeing. These therapies combine mindfulness, experiential, acceptance strategies with traditional behavior principles in order to attain lasting results. There are significant points of convergence between traditional CBT and therapies based on mindfulness meditation and acceptance. They are both empirically validated, based upon a theoretical model postulating that avoidance is key in the maintenance of psychopathology and they recommend an approach strategy in order to overcome the identified problem. They both use behavioral techniques in the context of a collaborative relationship in order to identify precise problems and to

In the research field of cognitive aging, games have gained attention as training interventions to remediate age-related deficits. Cognitive training games on computer, video and mobile platforms have shown ample and positive support. However, the generalized effects are not agreed upon unanimously, and the game tasks are usually simple and decontextualized due to the limitations of measurements. This study adopted a qualitative approach of design-based research (DBR) to systematically review and pragmatically examine the regime, presentation and feedback design of a cognitive training game for older adults. An overview of the literature of cognitive aging and training games was conducted to form the theoretical conjectures of the design, and an iterative cycle and process were employed to develop a mobile game for older adults who are homebound or receiving care in a nursing home. Stakeholders, i.e., elderly users and institutional administrators, were invited to participate in the design process. Using two cycles of design and evaluation, a working prototype of an iPad-based app that accounted for the needs of elderly adults in terms of form, appearance and working function was developed and tested in the actual contexts of the participants' homes and an assisted living facility. The results showed that the cognitive training game developed in this study was accepted by the participants, and a high degree of satisfaction was noted. Moreover, the elements of the interface, including its size, layout and control flow, were tested and found to be suitable for use. This study contributes to the literature by providing design suggestions for such games, including the designs of the cognitive training structure, interface, interaction, instructions and feedback, based on empirical evidence collected in natural settings.

Rule-based approach to cognitive modeling of real-time decision making

International Nuclear Information System (INIS)

Thorndyke, P.W.

1982-01-01

Recent developments in the fields of cognitive science and artificial intelligence have made possible the creation of a new class of models of complex human behavior. These models, referred to as either expert or knowledge-based systems, describe the high-level cognitive processing undertaken by a skilled human to perform a complex, largely mental, task. Expert systems have been developed to provide simulations of skilled performance of a variety of tasks. These include problems of data interpretation, system monitoring and fault isolation, prediction, planning, diagnosis, and design. In general, such systems strive to produce prescriptive (error-free) behavior, rather than model descriptively the typical human's errorful behavior. However, some research has sought to develop descriptive models of human behavior using the same theoretical frameworks adopted by expert systems builders. This paper presents an overview of this theoretical framework and modeling approach, and indicates the applicability of such models to the development of a model of control room operators in a nuclear power plant. Such a model could serve several beneficial functions in plant design, licensing, and operation

Treatment dropout is an important concern in eating disorder treatments as it has negative implications for patients' outcome, clinicians' motivation, and research studies. Our main objective was to conduct an exploratory study on treatment dropout in a two-part web-based cognitive behavioral therapy with asynchronous therapeutic support. The analysis included 205 female patients with eating disorders. Reasons for dropout, treatment experiences, and predictors of dropout were analyzed. Overall treatment dropout was 37.6%, with 18.5% early dropout (before or during treatment part 1) and 19.0% late dropout (after part 1 or during part 2). Almost half of the participants identified personal circumstances as reason for dropout. The other participants mostly reported reasons related to the online delivery or treatment protocol. Predictors of early dropout included reporting less vigor and smoking at baseline and a longer average duration per completed treatment module of part 1. Late dropout was predicted by reporting less vigor at baseline and uncertainty about recommendation of the treatment to others after completion of treatment part 1. Generally, the web-based treatment and online therapeutic support were evaluated positively, although dropouts rated the treatment as significantly less helpful and effective than completers did.

[Cognitive experimental approach to anxiety disorders].

Azaïs, F

1995-01-01

Cognitive psychology is proposing a functional model to explain the mental organisation leading to emotional disorders. Among these disorders, anxiety spectrum represents a domain in which this model seems to be interesting for an efficient and comprehensive approach of the pathology. Number of behavioral or cognitive psychotherapeutic methods are relating to these cognitive references, but the theorical concepts of cognitive "shemata" or cognitive "processes" evoked to describe mental functioning in anxiety need an experimental approach for a better rational understanding. Cognitive function as perception, attention or memory can be explored in this domaine in an efficient way, allowing a more precise study of each stage of information processing. The cognitive model proposed in the psychopathology of anxiety suggests that anxious subjects are characterized by biases in processing of emotionally valenced information. This hypothesis suggests functional interference in information processing in these subjects, leading to an anxious response to the most of different stimuli. Experimental approach permit to explore this hypothesis, using many tasks for testing different cognitive dysfunction evoked in the anxious cognitive organisation. Impairments revealed in anxiety disorders seem to result from specific biases in threat-related information processing, involving several stages of cognitive processes. Semantic interference, attentional bias, implicit memory bias and priming effect are the most often disorders observed in anxious pathology, like simple phobia, generalised anxiety, panic disorder or post-traumatic stress disorder. These results suggest a top-down organisation of information processing in anxious subjects, who tend to detect, perceive and label many situations as threatening experience. The processes of reasoning and elaboration are consequently impaired in their adaptative function to threat, leading to the anxious response observed in clinical

Compulsive gambling has received widespread attention in the last decade. Gambling has become the first non-chemical addiction, which went down to the section "Addiction and related disorders" of the modern DSM-V. The review considers non-pharmacological and pharmacological approaches to the treatment of gambling. Among non-drug approaches, cognitive-behavioral therapy and 12-step programs have gained the most popularity in the "Gamblers Anonymous" community. Among pharmacological approaches, three classes of drugs: antidepressants (mainly SSRIs), opiate antagonists (naltrexone and nalmefene) and mood stabilizers (valproate, lithium, topiramate) proved to be effective in treatment of gambling. No differences in the efficacy of the three classes of psychotropic drugs have been identified. Preliminary results for N-acetylcysteine and memantine cause optimism in terms of perspective.

2017-01-01

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder that often runs a chronic unremitting course. Treatment outcomes can be unsatisfactory despite the availability of various somatic and psychological therapies. Psychodynamic psychotherapy in combination with cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) could help patients with treatment-resistant OCD achieve better outcomes. An integrative approach can help patients gain insight, strengthen the therapeutic alliance, improve treatment adherence, and provide symptomatic relief when other treatments seem insufficient or have failed. We describe the treatment process of a person with treatment-resistant OCD who received pharmacotherapy, concurrent CBT/ERP, and a brief course of psychodynamic psychotherapy. Case formulations from cognitive behavioral and psychodynamic perspectives are presented. The authors discuss the advantages of doing a psychodynamic assessment and formulation in treatment refractory cases and the wisdom of integrating psychotherapy interventions for OCD, as well as the unique clinical features of cases that warrant a multimodal treatment approach.

The Integration of Cognitive Remediation Therapy into the Whole Psychosocial Rehabilitation Process: An Evidence-Based and Person-Centered Approach

Rafael Penadés

2012-01-01

Full Text Available Cognitive remediation therapies seem to ameliorate cognitive impairments in patients with schizophrenia. Interestingly, some improvement in daily functioning can also be expected as a result. However, to achieve these results it is necessary that cognitive remediation is carried out in the context of broader psychosocial rehabilitation involving the learning of other communication, social, and self-control skills. Unfortunately, little is known about how to integrate these different rehabilitation tools in broader rehabilitation programs. Based on both the neurocognitive behavioral approach and the action theory framework, a hierarchical flowchart is represented in this paper to integrate CRT with other evidence-based psychological therapies in outpatient settings. Finally, some evidence is provided in which cognitive abilities need to be targeted in remediation programs to improve functioning. In summary, to improve daily functioning, according to these studies, cognitive remediation needs to include the teaching of some cognitive strategies that target executive skills.

The cognitive based approach of capacity assessment in psychiatry: a philosophical critique of the MacCAT-T.

Science.gov (United States)

Breden, Torsten Marcus; Vollmann, Jochen

2004-12-01

This article gives a brief introduction to the MacArthur Competence Assessment Tool-Treatment (MacCAT-T) and critically examines its theoretical presuppositions. On the basis of empirical, methodological and ethical critique it is emphasised that the cognitive bias that underlies the MacCAT-T assessment needs to be modified. On the one hand it has to be admitted that the operationalisation of competence in terms of value-free categories, e.g. rational decision abilities, guarantees objectivity to a great extent; but on the other hand it bears severe problems. Firstly, the cognitive focus is in itself a normative convention in the process of anthropological value-attribution. Secondly, it misses the complexity of the decision process in real life. It is therefore suggested that values, emotions and other biographic and context specific aspects should be considered when interpreting the cognitive standards according to the MacArthur model. To fill the gap between cognitive and non-cognitive approaches the phenomenological theory of personal constructs is briefly introduced. In conclusion some main demands for further research to develop a multi-step model of competence assessment are outlined.

Since the introduction of Beck's cognitive theory of emotional disorders, and their treatment with psychotherapy, cognitive-behavioral approaches have become the most extensively researched psychological treatment for a wide variety of disorders. Despite this, the relative contribution of cognitive to behavioral approaches to treatment are poorly understood and the mechanistic role of cognitive change in therapy is widely debated. We critically review this literature, focusing on the mechanistic role of cognitive change across cognitive and behavioral therapies for depressive and anxiety disorders. Copyright © 2016.

Neurotransmitter-based strategies for the treatment of cognitive dysfunction in Down syndrome.

2014-10-03

Down syndrome (DS) is a multisystem disorder affecting the cardiovascular, respiratory, gastrointestinal, neurological, hematopoietic, and musculoskeletal systems and is characterized by significant cognitive disability and a possible common pathogenic mechanism with Alzheimer's disease. During the last decade, numerous studies have supported the notion that the triplication of specific genes on human chromosome 21 plays a significant role in cognitive dysfunction in DS. Here we reviewed studies in trisomic mouse models and humans, including children and adults with DS. In order to identify groups of genes that contribute to cognitive disability in DS, multiple mouse models of DS with segmental trisomy have been generated. Over-expression of these particular genes in DS can lead to dysfunction of several neurotransmitter systems. Therapeutic strategies for DS have either focused on normalizing the expression of triplicated genes with important roles in DS or restoring the function of these systems. Indeed, our extensive review of studies on the pathogenesis of DS suggests that one plausible strategy for the treatment of cognitive dysfunction is to target the cholinergic, serotonergic, GABA-ergic, glutamatergic, and norepinephrinergic system. However, a fundamental strategy for treatment of cognitive dysfunction in DS would include reducing to normal levels the expression of specific triplicated genes in affected systems before the onset of neurodegeneration.

Cognitive control is an important mental ability that is examined using a multitude of cognitive control tasks and effects. The present paper presents the first steps in the elaboration of a functional approach, which aims to uncover the communalities and differences between different cognitive control tasks and their effects. Based on the idea that responses in cognitive control tasks qualify as operant behaviour, we propose to reinterpret cognitive control tasks in terms of operant contingencies and cognitive control effects as instances of moderated stimulus control. We illustrate how our approach can be used to uncover communalities between topographically different cognitive control tasks and can lead to novel questions about the processes underlying cognitive control. © 2015 International Union of Psychological Science.

2017-01-01

Internet-delivered treatment has the potential to expand access to evidence-based cognitive-behavioral therapy (CBT) for pediatric headache, and has demonstrated efficacy in small trials for some youth with headache. We used a mixed methods approach to identify effective components of CBT for this population. In Study 1, component profile analysis identified common interventions delivered in published RCTs of effective CBT protocols for pediatric headache delivered face-to-face or via the Internet. We identified a core set of three treatment components that were common across face-to-face and Internet protocols: 1) headache education, 2) relaxation training, and 3) cognitive interventions. Biofeedback was identified as an additional core treatment component delivered in face-to-face protocols only. In Study 2, we conducted qualitative interviews to describe the perspectives of youth with headache and their parents on successful components of an Internet CBT intervention. Eleven themes emerged from the qualitative data analysis, which broadly focused on patient experiences using the treatment components and suggestions for new treatment components. In the Discussion, these mixed methods findings are integrated to inform the adaptation of an Internet CBT protocol for youth with headache.

Adolescents with anorexia nervosa who have obsessive-compulsive (OC) features respond poorly to family-based treatment (FBT). This study evaluated the feasibility of combining FBT with either cognitive remediation therapy (CRT) or art therapy (AT) to improve treatment response in this at-risk group. Thirty adolescents with anorexia nervosa and OC features were randomized to 15 sessions of FBT + CRT or AT. Recruitment rate was 1 per month, and treatment attrition was 16.6% with no differences between groups. Suitability, expectancy and therapeutic relationships were acceptable for both combinations. Correlations between changes in OC traits and changes in cognitive inefficiencies were found for both combinations. Moderate changes in cognitive inefficiencies were found in both groups but were larger in the FBT + AT combination. This study suggests that an RCT for poor responders to FBT because of OC traits combining FBT with either CRT or AT is feasible to conduct.

McKenna, Laurence; Marks, Elizabeth M; Hallsworth, Christopher A; Schaette, Roland

2017-01-01

Tinnitus is experienced by up to 15% of the population and can lead to significant disability and distress. There is rarely a medical or surgical target and psychological therapies are recommended. We investigated whether mindfulness-based cognitive therapy (MBCT) could offer an effective new therapy for tinnitus. This single-site randomized controlled trial compared MBCT to intensive relaxation training (RT) for chronic, distressing tinnitus in adults. Both treatments involved 8 weekly, 120-min sessions focused on either relaxation (RT) or mindfulness meditation (MBCT). Assessments were completed at baseline and at treatment commencement 8 weeks later. The primary outcomes were tinnitus severity (Tinnitus Questionnaire) and psychological distress (Clinical Outcomes in Routine Evaluation - Non-Risk, CORE-NR), 16 weeks after baseline. The analysis utilized a modified intention-to-treat approach. A total of 75 patients were randomly allocated to MBCT (n = 39) or RT (n = 36). Both groups showed significant reductions in tinnitus severity and loudness, psychological distress, anxiety, depression, and disability. MBCT led to a significantly greater reduction in tinnitus severity than RT, with a mean difference of 6.3 (95% CI 1.3-11.4, p = 0.016). Effects persisted 6 months later, with a mean difference of 7.2 (95% CI 2.1-2.3, p = 0.006) and a standardized effect size of 0.56 (95% CI 0.16-0.96). Treatment was effective regardless of initial tinnitus severity, duration, or hearing loss. MBCT is effective in reducing tinnitus severity in chronic tinnitus patients compared to intensive RT. It also reduces psychological distress and disability. Future studies should explore the generalizability of this approach and how outcome relates to different aspects of the intervention. © 2017 The Author(s) Published by S. Karger AG, Basel.

2015-01-01

The use of data from people with cognitive impairments to inform theories of cognition is an established methodology, particularly in the field of cognitive neuropsychology. However, it is less well known that studies that aim to improve cognitive functioning using treatment can also inform our understanding of cognition. This paper discusses a range of challenges that researchers face when testing theories of cognition and particularly when using treatment as a tool for doing so. It highlights the strengths of treatment methodology for testing causal relations and additionally discusses how generalization of treatment effects can shed light on the nature of cognitive representations and processes. These points are illustrated using examples from the Special Issue of Cognitive Neuropsychology entitled Treatment as a tool for investigating cognition.

Today, it is present in literary and objective knowledge studies, as well as in studies of users,information brokers and systems of information retrieval.Cognitive approach exercises strong impact on several scientific disciplines which are grouped under the roof of cognitive science. The cognitive approach has caused split and the formation of a new paradigm, i.e. the cognitive paradigm, in many scientific disciplines.In the frames of the definition of Kuhn's concept of paradigm, it is evident that librarianship and information science are on the pre-paradigmatic level. I Iowever,some authors mention the existence of at least two paradigms in library and information science, i.e. physical and cognitive paradigm.The hištorical overview of cognitive oriented research works of Brookes, De Mey,Belkin, Ingwersen and others enables the insight into the development of library and information scientific thought up to the present.

Behavioral facilitation: a cognitive model of individual differences in approach motivation.

Robinson, Michael D; Meier, Brian P; Tamir, Maya; Wilkowski, Benjamin M; Ode, Scott

2009-02-01

Approach motivation consists of the active, engaged pursuit of one's goals. The purpose of the present three studies (N = 258) was to examine whether approach motivation could be cognitively modeled, thereby providing process-based insights into personality functioning. Behavioral facilitation was assessed in terms of faster (or facilitated) reaction time with practice. As hypothesized, such tendencies predicted higher levels of approach motivation, higher levels of positive affect, and lower levels of depressive symptoms and did so across cognitive, behavioral, self-reported, and peer-reported outcomes. Tendencies toward behavioral facilitation, on the other hand, did not correlate with self-reported traits (Study 1) and did not predict avoidance motivation or negative affect (all studies). The results indicate a systematic relationship between behavioral facilitation in cognitive tasks and approach motivation in daily life. Results are discussed in terms of the benefits of modeling the cognitive processes hypothesized to underlie individual differences motivation, affect, and depression.

Full Text Available Introduction & Purpose: Cognitive-behavioral stress management therapy refers to a family of stress management interventions that are based on cognitive-behavioral approach. The stress management increases the ability of people to reduce stress and cope with stress-eliciting situations. The present study tries to explain the effectiveness of group-based stress management cognitive-behavioral therapy in the improvement of life quality among the women whose husbands take methadone in their treatments. Methods: The present study is a semi-empirical intervention that uses a pre- and- post- test design with a control group. The statistical universe in the present study consisted of all the women whose husbands were receiving methadone treatment in Tasmim Addiction Treatment Center in Khoramabad City in 2013. Among the women who came to this center to take weekly classes for instructions useful in family interactions, 24 were selected on the basis of availability sampling and in accordance with the criteria assumed in this study, that is, the women who had the lowest scores on the scale of life quality. They were randomly assigned to the experimental group (N=12 and the control group (N=12. The instrument used in this study was the World Health Organization Quality of Life Questionnaire (WHOQOL, 1996, which was completed by subjects in two per-test and post- test phases. The project (the stress management cognitive-behavioral therapy was implemented on the basis of the Antony et al Manual in ten two-hour sessions with a group technique and with an interval of one session per week for the participants in the experimental group, without any intervention for the control group. At the end of therapeutic sessions, the two groups were again evaluated (the post- test phase. The data of the present study were analyzed by means of the univariate covariance analysis test (ANCOVA and the statistical software SPSS18. Results: Results indicated that the life

This study compares different versions of mirror exposure (ME), a body image intervention with research support. ME protocols were adapted to maximize control and comparability, and scripted for delivery by research assistants. Female undergraduates (N=168) were randomly assigned to receive mindfulness-based (MB; n=58), nonjudgmental (NJ; n=55), or cognitive dissonance-based (CD, n=55) ME. Participants completed the Body Image Avoidance Questionnaire (BIAQ), Body Checking Questionnaire (BCQ), Satisfaction with Body Parts Scale (SBPS), Beck Depression Inventory-II (BDI-II), and Eating Disorders Examination Questionnaire (EDE-Q) at pre-treatment, post-treatment, and 1-month follow-up. Mixed models ANOVAs revealed a significant main effect of time on all measures, and no significant time by condition interaction for any measures except the SBPS. Post-hoc analysis revealed that only CD ME significantly improved SBPS outcome. Results suggest that all versions of ME reduce eating disorder risk factors, but only CD ME improves body satisfaction.

2018-03-01

Patient adherence has been identified as an important barrier to the implementation of evidence-based psychological treatments. In cognitive behavioral treatments (CBT) for insomnia, the current study examined (a) the validity of therapist ratings of patient agreement and adherence against an established behavioral measure of adherence, and (b) the relationship between treatment agreement, adherence, and outcome. Participants were 188 adults meeting DSM-IV-TR criteria for chronic insomnia who were randomized to receive behavior therapy, cognitive therapy, or CBT for insomnia. Treatment agreement/adherence was measured by (a) weekly therapist ratings of patient agreement and homework completion, and (b) adherence to behavioral strategies (ABS) derived from patient-reported sleep diary. Outcome measures were Insomnia Severity Index and insomnia remission (Insomnia Severity Index adherence, and ABS measures during treatment significantly predicted insomnia remission at posttreatment, and all but therapist rating of homework completion predicted remission at 6-month follow-up. Greater patient agreement and adherence (therapist ratings and ABS) during treatment predicted better treatment outcome. Therapist-rated treatment agreement and adherence correspond well with patient-reported sleep diary-derived adherence measure. These simple, deployable therapist-rated patient agreement and adherence can potentially be useful for treatments for other disorders. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Cognitive functioning can be assessed with performance-based assessments such as neuropsychological tests and with interview-based assessments. Both assessment methods have the potential to assess whether treatments for schizophrenia improve clinically relevant aspects of cognitive impairment. However, little is known about the reliability, validity and treatment responsiveness of interview-based measures, especially in the context of clinical trials. Data from two studies were utilized to assess these features of the Schizophrenia Cognition Rating Scale (SCoRS). One of the studies was a validation study involving 79 patients with schizophrenia assessed at 3 academic research centers in the US. The other study was a 32-site clinical trial conducted in the US and Europe comparing the effects of encenicline, an alpha-7 nicotine agonist, to placebo in 319 patients with schizophrenia. The SCoRS interviewer ratings demonstrated excellent test-retest reliability in several different circumstances, including those that did not involve treatment (ICC> 0.90), and during treatment (ICC>0.80). SCoRS interviewer ratings were related to cognitive performance as measured by the MCCB (r=-0.35), and demonstrated significant sensitivity to treatment with encenicline compared to placebo (Pcognition in schizophrenia, and may be useful for clinical practice. The weaknesses of the SCoRS include its reliance on informant information, which is not available for some patients, and reduced validity when patient's self-report is the sole information source.

Research has demonstrated that both memory and learning for treatment contents are poor, and that both are associated with worse treatment outcome. The Memory Support Intervention has been shown to improve memory for treatment, but it has not yet been established if this intervention can also improve learning of treatment contents. This study was designed to document the number of times participants exhibited each of the indices of learning, to examine the indices of learning and their relationship to recall of treatment points, and to investigate the association between the indices of learning and depression outcome. Adults diagnosed with major depressive disorder (N = 48) were randomly assigned to 14 sessions of cognitive therapy-as-usual (CT-as-usual) or cognitive therapy plus the Memory Support Intervention (CT + Memory Support). Measures of learning, memory, and depressive symptomatology were taken at mid-treatment, post-treatment, and at 6-month follow-up. Relative to the CT-as-usual group, participants in the CT + Memory Support group reported more accurate thoughts and applications of treatment points at mid-treatment, post-treatment, and 6-month follow-up. Patient recall was significantly correlated with application and cognitive generalization. Thoughts and application at mid-treatment were associated with increased odds of treatment response at post-treatment. The learning measure for this study has not yet been psychometrically validated. The results are based on a small sample. Learning during treatment is poor, but modifiable via the Memory Support Intervention. These results provide encouraging data that improving learning of treatment contents can reduce symptoms during and following treatment. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cognitive approaches to emotions.

Science.gov (United States)

Oatley, Keith; Johnson-Laird, P N

2014-03-01

Cognitive approaches offer clear links between how emotions are thought about in everyday life and how they are investigated psychologically. Cognitive researchers have focused on how emotions are caused when events or other people affect concerns and on how emotions influence processes such as reasoning, memory, and attention. Three representative cognitive theories of emotion continue to develop productively: the action-readiness theory, the core-affect theory, and the communicative theory. Some principles are common to them and divergences can be resolved by future research. Recent explanations have included how emotions structure social relationships, how they function in psychological illnesses, and how they are central to music and fiction.

Buckman, Jennifer F; Bates, Marsha E; Cisler, Ron A

2007-09-01

Mechanisms of behavioral change that support positive addiction treatment outcomes in individuals with co-occurring alcohol-use disorders and cognitive impairment remain largely unknown. This article combines person- and variable-centered approaches to examine the interrelated influence of cognitive impairment and social support on stability of and changes in drinking behaviors of Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity) outpatients and aftercare clients (N = 1,726) during the first year after their entry into treatment. Latent class analysis identified homogeneous groups of clients based on the nature and extent of social support for abstinence or drinking at treatment entry. Cognitive impairment and drinking outcomes were compared across latent classes, and the interaction between impairment and social support on drinking outcomes was examined using mixture probit regression. Three independent social support classes (frequent positive, limited positive, and negative) were identified. In the outpatient sample, the frequent positive support class had greater cognitive impairment at treatment entry versus other classes, and extent of impairment significantly predicted improved drinking outcomes in this class. In the aftercare sample, the frequent positive and negative support classes had heightened impairment, yet cognitive impairment significantly predicted relatively poorer drinking outcomes in the negative support class only. Cognitive impairment may increase the influence of the social network on the drinking outcomes of persons receiving treatment for alcohol-use disorders, but more research is needed to understand client characteristics that determine whether this influence is more likely to be manifest as increased salience of helping agents or of hindering agents in the social network.

Positive affect and cognitive control: approach-motivation intensity influences the balance between cognitive flexibility and stability.

Science.gov (United States)

Liu, Ya; Wang, Zhenhong

2014-05-01

In most prior research, positive affect has been consistently found to promote cognitive flexibility. However, the motivational dimensional model of affect assumes that the influence of positive affect on cognitive processes is modulated by approach-motivation intensity. In the present study, we extended the motivational dimensional model to the domain of cognitive control by examining the effect of low- versus high-approach-motivated positive affect on the balance between cognitive flexibility and stability in an attentional-set-shifting paradigm. Results showed that low-approach-motivated positive affect promoted cognitive flexibility but also caused higher distractibility, whereas high-approach-motivated positive affect enhanced perseverance but simultaneously reduced distractibility. These results suggest that the balance between cognitive flexibility and stability is modulated by the approach-motivation intensity of positive affective states. Therefore, it is essential to incorporate motivational intensity into studies on the influence of affect on cognitive control.

In this paper will be presented new opportunities for developing innovative solutions for semantic pattern classification and visual cryptography, which will base on cognitive and bio-inspired approaches. Such techniques can be used for evaluation of the meaning of analyzed patterns or encrypted information, and allow to involve such meaning into the classification task or encryption process. It also allows using some crypto-biometric solutions to extend personalized cryptography methodologies based on visual pattern analysis. In particular application of cognitive information systems for semantic analysis of different patterns will be presented, and also a novel application of such systems for visual secret sharing will be described. Visual shares for divided information can be created based on threshold procedure, which may be dependent on personal abilities to recognize some image details visible on divided images.

Cognitive hypnotherapy for major depressive disorder.

Alladin, Assen

2012-04-01

Since the publication of the special issue on cognitive hypnotherapy in the Journal of Cognitive Psychotherapy: An International Quarterly (1994), there have been major developments in the application of hypnosis to the treatment of depression. However, there is no "one-size-fits-all" treatment for depressive disorders as the conditions represent a complex set of heterogeneous symptoms, involving multiple etiologies. It is thus important for therapists to promote a multimodal approach to treating depressive disorders. This article describes cognitive hypnotherapy (CH), an evidence-based multimodal psychological treatment that can be applied to a wide range of depressed patients. CH combines hypnosis with cognitive behavior therapy as the latter provides the best integrative lodestone for assimilating empirically supported treatment techniques derived from various psychotherapies.

To examine cognitive and affective mechanisms underlying mindfulness-based addiction treatment (MBAT) versus cognitive-behavioral therapy (CBT) and usual care (UC) for smoking cessation. Participants in the parent study from which data were drawn (N = 412; 54.9% female; 48.2% African American, 41.5% non-Latino White, 5.4% Latino, 4.9% other; 57.6% annual income <$30,000) were randomized to MBAT (n = 154), CBT (n = 155), or UC (n = 103). From quit date through 26 weeks postquit, participants completed measures of emotions, craving, dependence, withdrawal, self-efficacy, and attentional bias. Biochemically confirmed 7-day smoking abstinence was assessed at 4 and 26 weeks postquit. Although the parent study did not find a significant treatment effect on abstinence, mixed-effects regression models were conducted to examine treatment effects on hypothesized mechanisms, and indirect effects of treatments on abstinence were tested. Participants receiving MBAT perceived greater volitional control over smoking and evidenced lower volatility of anger than participants in both other treatments. However, there were no other significant differences between MBAT and CBT. Compared with those receiving UC, MBAT participants reported lower anxiety, concentration difficulties, craving, and dependence, as well as higher self-efficacy for managing negative affect without smoking. Indirect effects of MBAT versus UC on abstinence occurred through each of these mechanisms. Whereas several differences emerged between MBAT and UC, MBAT and CBT had similar effects on several of the psychosocial mechanisms implicated in tobacco dependence. Results help to shed light on similarities and differences between mindfulness-based and other active smoking cessation treatments. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Internet appearance was one of the main breakthroughs for the mankind in the latest decades. It revolutionized our lives in many aspects and brought about many undeniably positive changes. However, at the same time caused negative consequences. It has led to the emergence of the Internet addiction (IA). The paper is concerned with the issue of treatment of IA. The paper reviews the current findings on the approaches to IA treatment and evaluates their effectiveness. The main focus of the article concentrates on cognitive and pharmacologic treatment. The individual approach to IA treatment is advisable. Among drugs for the management of IA, antidepressants, antipsychotics, opioid receptor antagonists, glutamate receptor antagonists, and psychostimulants may be recommended. Some antiepileptics, and especially valproate, are considered as potential drugs for the treatment of IA. Effective therapy may require an individual approach and best results are expected when psychological and pharmacological treatments are combined.

2012-07-01

Cognitive impairments in individuals with alcohol dependence may interfere with the progress of treatment and contribute to the progression of the disease. This study aimed to determine whether cognitive remediation (CR) therapy applied during treatment for alcohol dependence improves cognitive functioning in alcohol-dependent inpatients. A secondary aim was to evaluate whether the benefits of CR generalize to noncognitive clinically meaningful outcomes at the end of inpatient treatment. Forty-one alcohol-dependent patients entering inpatient treatment for alcohol dependence were randomly assigned to receive conventional treatment (n = 21) or an additional 12 sessions of computer-assisted CR focusing on cognitive enhancement in attention/executive function and memory domains (n = 20). Assessments of cognitive abilities in these domains as well as of psychological well-being and alcohol craving were conducted at baseline (at the beginning of inpatient treatment) and after CR (at the end of treatment). Results indicated that, relative to patients completing conventional treatment, those who received supplemental CR showed significant improvement in attention/executive function and memory domains, particularly in attention (alertness, divided attention), working memory, and delayed memory (recall). In addition, patients receiving CR during alcohol-dependence treatment showed significantly greater improvements in psychological well-being (Symptom Checklist-90-Revised) and in the compulsion aspect of craving (Obsessive Compulsive Drinking Scale-German version). CR during inpatient treatment for alcohol dependence is effective in improving cognitive impairments in alcohol-dependent patients. The benefits generalize to noncognitive outcomes, demonstrating that CR may be an efficacious adjunctive intervention for the treatment of alcohol dependence.

Subcranial approach in the surgical treatment of anterior skull base trauma.

Schaller, B

2005-04-01

Fractures of the anterior skull base, because of the region's anatomical relationships, are readily complicated by neurological damage to the brain or cranial nerves. This review highlights the use of a subcranial approach in the operative treatment of injuries of the anterior skull base and compares it to the more traditional neurosurgical transcranial approach. The extended anterior subcranial approach takes advantage of the specific features of injuries in this region and allows direct access to the central anterior cranial base in order to repair fractures, close CSF fistulae and relieve of optic nerve compression. It avoids extensive frontal lobe manipulation. The success of the approach in achieving the aims of surgery with low morbidity is reviewed.

Disordered gamblers have phenotypical and pathological similarities to those with substance use disorders (SUD), including exaggerated automatic cognitive processing of motivationally salient gambling cues in the environment (i.e., attentional and approach bias). Cognitive bias modification (CBM) is a family of computerised interventions that have proved effective in successfully re-training these automatic cognitive biases in SUD. CBM interventions can, in principle, be administered online, thus showing potential of being a low-cost, low-threshold addition to conventional treatments. This paper presents the design of a pilot randomised controlled trial exploring the effectiveness of two web-based CBM interventions targeting attentional and approach bias towards gambling cues in a sample of Dutch and Belgian problematic and pathological gamblers. Participants (N = 182) are community-recruited adults experiencing gambling problems, who have gambled at least twice in the past 6 months and are motivated to change their gambling behaviour. After a baseline assessment session, participants are randomly assigned to one of four experimental conditions (attentional or approach bias training, or the placebo version of the two trainings) and complete six sessions of training. At baseline and before each training session, participants receive automated personalised feedback on their gambling motives and reasons to quit or reduce gambling. The post-intervention, 1-month, and 3-month follow-up assessments will examine changes in gambling behaviour, with frequency and expenditure as primary outcomes, and depressive symptoms and gambling-related attentional and approach biases as secondary outcomes. Secondary analyses will explore possible moderators (interference control capacity and trait impulsivity) and mediators (change in cognitive bias) of training effects on the primary outcomes. This study is the first to explore the effectiveness of an online CBM intervention for

The evaluation of cognitive functions can be performed using two approaches: a quantitative one, based on screening tools; a qualitative one, based on the examination of specific cognitive functions. The quantitative approach offers a pragmatic process: to screen rapidly for a cognitive dysfunction that may require assistance or treatments. We will present three screening tools and their diagnostic value: the clock test, the Mini Mental State Examination and the Montreal Cognitive Assessment. They help select patients who require a more detailed examination to precisely diagnose their cognitive dysfunction. We propose a way to perform a detailed cognitive examination at the bedside, including the examination of alertness, attention, memory, language, frontal functions, praxis and hemi-neglect. This simple examination indicates the location of the cerebral lesion and sometimes suggests the underlying disease. Copyright © 2015. Published by Elsevier SAS.

Improving the learning of clinical reasoning through computer-based cognitive representation.

Wu, Bian; Wang, Minhong; Johnson, Janice M; Grotzer, Tina A

2014-01-01

Clinical reasoning is usually taught using a problem-solving approach, which is widely adopted in medical education. However, learning through problem solving is difficult as a result of the contextualization and dynamic aspects of actual problems. Moreover, knowledge acquired from problem-solving practice tends to be inert and fragmented. This study proposed a computer-based cognitive representation approach that externalizes and facilitates the complex processes in learning clinical reasoning. The approach is operationalized in a computer-based cognitive representation tool that involves argument mapping to externalize the problem-solving process and concept mapping to reveal the knowledge constructed from the problems. Twenty-nine Year 3 or higher students from a medical school in east China participated in the study. Participants used the proposed approach implemented in an e-learning system to complete four learning cases in 4 weeks on an individual basis. For each case, students interacted with the problem to capture critical data, generate and justify hypotheses, make a diagnosis, recall relevant knowledge, and update their conceptual understanding of the problem domain. Meanwhile, students used the computer-based cognitive representation tool to articulate and represent the key elements and their interactions in the learning process. A significant improvement was found in students' learning products from the beginning to the end of the study, consistent with students' report of close-to-moderate progress in developing problem-solving and knowledge-construction abilities. No significant differences were found between the pretest and posttest scores with the 4-week period. The cognitive representation approach was found to provide more formative assessment. The computer-based cognitive representation approach improved the learning of clinical reasoning in both problem solving and knowledge construction.

Realizing an Optimization Approach Inspired from Piaget’s Theory on Cognitive Development

Directory of Open Access Journals (Sweden)

Utku Kose

2015-09-01

Full Text Available The objective of this paper is to introduce an artificial intelligence based optimization approach, which is inspired from Piaget’s theory on cognitive development. The approach has been designed according to essential processes that an individual may experience while learning something new or improving his / her knowledge. These processes are associated with the Piaget’s ideas on an individual’s cognitive development. The approach expressed in this paper is a simple algorithm employing swarm intelligence oriented tasks in order to overcome single-objective optimization problems. For evaluating effectiveness of this early version of the algorithm, test operations have been done via some benchmark functions. The obtained results show that the approach / algorithm can be an alternative to the literature in terms of single-objective optimization.The authors have suggested the name: Cognitive Development Optimization Algorithm (CoDOA for the related intelligent optimization approach.

Alcohol dependence constitutes a serious worldwide public health problem. The last few decades have seen many pharmacological studies devoted to the improvement of alcoholism treatment. Although psychosocial treatments (e.g. individual or group therapy) have historically been the mainstay of alcoholism treatment, a successful approach for alcohol dependence consists in associating pharmacologic medications with therapy, as 40-70% of patients following only psychosocial therapy typically resume alcohol use within a year of post-detoxification treatment. Nowadays, two main pharmacological options, naltrexone and acomprosate, both approved by the US Food and Drug Administration, are available and seemingly improve on the results yielded by standard techniques employed in the management of alcoholism. However, insufficient data exist to confirm the superiority of one drug over the other, and research is ongoing to determine what type of alcohol-dependent individual benefits the most from using either medication. Available data on the application of both drugs clearly suggest different practical applications. Thus, a fundamental question remains as to how we can identify which alcoholic patients are likely to benefit from the use of naltrexone, acamprosate or both, and which are not. The aim of the present manuscript is to suggest the use of cognitive event-related potentials as an interesting way to identify subgroups of alcoholic patients displaying specific clinical symptoms and cognitive disturbances. We propose that this may help clinicians improve their treatment of alcoholic patients by focusing therapy on individual cognitive disturbances, and by adapting the pharmaceutical approach to the specific needs of the patient.

Individuals with public speaking anxiety (PSA) experience fear and avoidance that can cause extreme distress, impaired speaking performance, and associated problems in psychosocial functioning. Most extant interventions for PSA emphasize anxiety reduction rather than enhancing behavioral performance. We compared the efficacy of two brief cognitive-behavioral interventions, a traditional cognitive-behavior treatment (tCBT) and an acceptance-based behavior treatment (ABBT), on public speaking performance and anxiety in a clinical sample of persons with PSA. The effects of treatment on prefrontal brain activation were also examined. Participants (n = 21) were randomized to 90 min of an ABBT or a tCBT intervention. Assessments took place at pre- and post-treatment and included self-rated anxiety and observer-rated performance measures, a behavioral assessment, and prefrontal cortical activity measurements using functional near-infrared spectroscopy (fNIRS). Exploratory results indicated that participants in the ABBT condition experienced greater improvements in observer-rated performance relative to those in the tCBT condition, while those in the tCBT condition experienced greater reductions in subjective anxiety levels. Individuals in the ABBT condition also exhibited a trend toward greater treatment-related reductions in blood volume in the left dorsolateral prefrontal cortex relative to those who received tCBT. Overall, these findings preliminarily suggest that acceptance-based treatments may free more cognitive resources in comparison with tCBT, possibly resulting in greater improvements in objectively rated behavioral performances for ABBT interventions. © The Author(s) 2016.

Clinical variables that affect treatment outcome for marijuana dependent individuals are not yet well understood, including the effects of cognitive functioning. To address this, level of cognitive functioning and treatment outcome were investigated. Twenty marijuana-dependent outpatients were administered a neuropsychological battery at treatment entry. All patients received 12 weekly individual sessions of combined motivational enhancement therapy and cognitive behavioral therapy. The Wilcoxon Exact Test was used to compare cognitive functioning test scores between completers and dropouts, and the Fisher Exact Test was used to compare proportion of negative urines between those with higher and lower scores on the cognitive tests. Marijuana abstinence was unrelated to cognitive functioning. However, dropouts scored significantly lower than completers on measures of abstract reasoning and processing accuracy, providing initial evidence that cognitive functioning plays a role in treatment retention of adult marijuana dependent patients. If supported by further studies, the findings may help inform the development of interventions tailored for cognitively impaired marijuana dependent patients. PMID:18329188

MBCT is based on the notion that meditation helps individuals effectively deploy and regulate attention to effectively manage and treat a range of psychological symptoms, including emotional responses to stress, anxiety, and depression. Several studies demonstrate that mindfulness approaches can effectively reduce negative emotional reactions that result from and/or exacerbate psychiatric difficulties and exposure to stressors among children, adolescents, and their parents. Mindfulness may be particularly relevant for youth with maladaptive cognitive processes such as rumination. Clinical experience regarding the utility of mindfulness-based approaches, including MBCT, is being increasingly supported by empirical studies to optimize the effective treatment of youth with a range of challenging symptoms. This paper provides a description of MBCT, including mindfulness practices, theoretical mechanisms of action, and targeted review of studies in adolescents.

Selective mutism (SM) is a debilitating childhood anxiety disorder characterized by a persistent lack of speech in certain social settings and is considered hard to treat. Cognitive behavioral therapy (CBT) and pharmacological treatments are the best described treatments in the literature. To test whether there is evidence on treatment based on CBT, medication or a combination of these. Systematic and critical review of the literature on CBT and/or pharmacological treatments of SM. Literature was sought on PubMed, Embase and Psycinfo in March 2017. Of the included studies, six examined CBT, seven pharmacologic treatment and two a combination of these. Using CBT 53/60 children improved symptomatically whilst respectively 55/67 and 6/7 improved using pharmacologic- and combination-treatment. Pharmacologic treatment and especially CBT showed promising results supported by some degree of evidence, which combination treatment lacks. Yet small numbers, few RCTs, heterogeneous study designs, lack of consistent measures, short treatment and follow-up periods, generally limits the evidence. This needs focus in future research.

New approaches to addiction treatment based on learning and memory.

Science.gov (United States)

Kiefer, Falk; Dinter, Christina

Preclinical studies suggest that physiological learning processes are similar to changes observed in addicts at the molecular, neuronal, and structural levels. Based on the importance of classical and instrumental conditioning in the development and maintenance of addictive disorders, many have suggested cue-exposure-based extinction training of conditioned, drug-related responses as a potential new treatment of addiction. It may also be possible to facilitate this extinction training with pharmacological compounds that strengthen memory consolidation during cue exposure. Another potential therapeutic intervention would be based on the so-called reconsolidation theory. According to this hypothesis, already-consolidated memories return to a labile state when reactivated, allowing them to undergo another phase of consolidation-reconsolidation, which can be pharmacologically manipulated. These approaches suggest that the extinction of drug-related memories may represent a viable treatment strategy in the future treatment of addiction.

Improving the learning of clinical reasoning through computer-based cognitive representation

Full Text Available Objective: Clinical reasoning is usually taught using a problem-solving approach, which is widely adopted in medical education. However, learning through problem solving is difficult as a result of the contextualization and dynamic aspects of actual problems. Moreover, knowledge acquired from problem-solving practice tends to be inert and fragmented. This study proposed a computer-based cognitive representation approach that externalizes and facilitates the complex processes in learning clinical reasoning. The approach is operationalized in a computer-based cognitive representation tool that involves argument mapping to externalize the problem-solving process and concept mapping to reveal the knowledge constructed from the problems. Methods: Twenty-nine Year 3 or higher students from a medical school in east China participated in the study. Participants used the proposed approach implemented in an e-learning system to complete four learning cases in 4 weeks on an individual basis. For each case, students interacted with the problem to capture critical data, generate and justify hypotheses, make a diagnosis, recall relevant knowledge, and update their conceptual understanding of the problem domain. Meanwhile, students used the computer-based cognitive representation tool to articulate and represent the key elements and their interactions in the learning process. Results: A significant improvement was found in students’ learning products from the beginning to the end of the study, consistent with students’ report of close-to-moderate progress in developing problem-solving and knowledge-construction abilities. No significant differences were found between the pretest and posttest scores with the 4-week period. The cognitive representation approach was found to provide more formative assessment. Conclusions: The computer-based cognitive representation approach improved the learning of clinical reasoning in both problem solving and knowledge

Substance use is common among adolescents with post-traumatic stress disorder (PTSD). We aimed to develop and study an integrated treatment for adolescents with co-occurring disorders. This is a therapy development and open pilot trial study of a manualized therapy for adolescents with post-traumatic stress, depression, and substance use that uses a combination of cognitive therapy (CT) and mindfulness. Descriptive statistics and paired sample t-tests were calculated to assess for changes in PTSD symptoms, depression, and substance use frequency from baseline to end of treatment using standardized measures and validated by urine drug screens. We also examined for safety, predictors of clinical outcomes, and treatment retention. Thirty-seven adolescents participated in the study; 62% were study completers as defined by retention for at least 6 weeks of treatment. There were significant improvements in PTSD and depression symptoms from baseline to end of treatment, reflecting medium effect sizes, and which was associated with changes in trauma-associated cognitions. There was a reduction in cannabis use, which was the most commonly used substance. Preliminary results suggest feasibility, safety, and potential clinical effectiveness of an integrated therapy for adolescents with PTSD, depression, and substance use. Retention was comparable to other therapy clinical trial studies of adolescents despite the high risk for poor treatment retention and poor clinical outcomes among adolescents with PTSD and co-occurring disorders. We discuss the rationale for continued research of this mindfulness-based CT for adolescents with co-occurring disorders. Adolescents with co-occurring PTSD and substance use achieved meaningful improvement in PTSD and depression symptom severity after receiving a CT and mindfulness dual diagnosis approach. An integrated manualized therapy for dual diagnosis shows promise for reducing cannabis use in adolescents with PTSD. Changes in trauma

Full Text Available Abstract Background Atypical antipsychotics provide better control of the negative and affective symptoms of schizophrenia when compared with conventional neuroleptics; nevertheless, their heightened ability to improve cognitive dysfunction remains a matter of debate. This study aimed to examine the changes in cognition associated with long-term antipsychotic treatment and to evaluate the effect of the type of antipsychotic (conventional versus novel antipsychotic drugs on cognitive performance over time. Methods In this naturalistic study, we used a comprehensive neuropsychological battery of tests to assess a sample of schizophrenia patients taking either conventional (n = 13 or novel antipsychotics (n = 26 at baseline and at two years after. Results Continuous antipsychotic treatment regardless of class was associated with improvement on verbal fluency, executive functions, and visual and verbal memory. Patients taking atypical antipsychotics did not show greater cognitive enhancement over two years than patients taking conventional antipsychotics. Conclusions Although long-term antipsychotic treatment slightly improved cognitive function, the switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of these cognitive deficits.

The aim of this study was to identify treatment-specific predictors of the effectiveness of a method of evidence-based treatment: cognitive treatment of illness perceptions. This study focuses on what treatment works for whom, whereas most prognostic studies focusing on chronic non-specific low back pain rehabilitation aim to reduce the heterogeneity of the population of patients who are suitable for rehabilitation treatment in general. Three treatment-specific predictors were studied in patients with chronic non-specific low back pain receiving cognitive treatment of illness perceptions: a rational approach to problem-solving, discussion skills and verbal skills. Hierarchical linear regression analysis was used to assess their predictive value. Short-term changes in physical activity, measured with the Patient-Specific Functioning List, were the outcome measure for cognitive treatment of illness perceptions effect. A total of 156 patients with chronic non-specific low back pain participated in the study. Rational problem-solving was found to be a significant predictor for the change in physical activity. Discussion skills and verbal skills were non-significant. Rational problem-solving explained 3.9% of the total variance. The rational problem-solving scale results are encouraging, because chronic non-specific low back pain problems are complex by nature and can be influenced by a variety of factors. A minimum score of 44 points on the rational problem-solving scale may assist clinicians in selecting the most appropriate candidates for cognitive treatment of illness perceptions.

Purpose Cognitive impairment is reported frequently by cancer survivors. There are no proven treatments. We evaluated a cognitive rehabilitation program (Insight) and compared it with standard care in cancer survivors self-reporting cognitive symptoms. Patients and Methods We recruited adult cancer survivors with a primary malignancy (excluding central nervous system malignancies) who had completed three or more cycles of adjuvant chemotherapy in the previous 6 to 60 months and reported persistent cognitive symptoms. All participants received a 30-minute telephone consultation and were then randomly assigned to the 15-week, home-based intervention or to standard care. Primary outcome was self-reported cognitive function (Functional Assessment of Cancer Therapy Cognitive Function [FACT-COG] perceived cognitive impairment [PCI] subscale): difference between groups after intervention (T2) and 6 months later (T3). Results A total of 242 participants were randomly assigned: median age, 53 years; 95% female. The primary outcome of difference in FACT-COG PCI was significant, with less PCI in the intervention group at T2 ( P cognitive symptoms compared with standard care. To our knowledge, this is the first large randomized controlled trial showing an improvement in self-reported cognitive function in cancer survivors, indicating that this intervention is a feasible treatment.

It has been a long time since subjective tinnitus cases were described for the first time but they still lack a treatment with proven effectiveness. The main goal of this study was to evaluate the effectiveness of cognitive behavioural therapy in these patients. Between 2012 and 2013, 310 patients that suffered from subjective tinnitus were studied. Of these, 267 were included in treatment based on cognitive behavioural therapy. The monitoring period lasted 18 months for most cases, while it lasted 21 months for 11 patients. Considering patients that interrupted their treatment as failures, the percentage of recovery was 95.7%. Cognitive behavioural therapy should always be included in the treatment of people suffering from tinnitus.

Selective mutism (SM) is characterised by limited or a lack of speech in selected social settings. Recent reviews suggest that cognitive-behavioural therapy (CBT) is an effective and promising treatment approach for SM. However, there is still a lack of studies documenting the applicability of CBT for SM in diverse populations. The goal of the present study was to examine the use of a web-based CBT programme ('Meeky Mouse') among Singaporean children diagnosed with SM. Five children with SM (one boy and four girls aged 6-11 years) participated in the 14-week 'Meeky Mouse' programme, in addition to being prescribed with an unchanged dosage of fluoxetine 10-20 mg daily. The progress made by the children throughout the course of the programme was documented by the therapist. Post treatment, four out of the five children demonstrated improvements in the frequency of speech during therapy sessions at home, in school and at other social situations. Findings from the present study provide support for the use of a web-based CBT programme in improving speech and decreasing the severity of SM among affected children.

Full Text Available Objectives: Little is known about the differences between urban and rural gamblers in Australia, in terms of comorbidity and treatment outcome. Health disparities exist between urban and rural areas in terms of accessibility, availability, and acceptability of treatment programs for problem gamblers. However, evidence supporting cognitive-behaviour therapy as the main treatment for problem gamblers is strong. This pilot study aimed to assess the outcome of a Cognitive-Behavioural Therapy (CBT treatment program offered to urban and rural treatment-seeking gamblers. Methods: People who presented for treatment at a nurse-led Cognitive-Behavioural Therapy (CBT gambling treatment service were invited to take part in this study. A standardised clinical assessment and treatment service was provided to all participants. A series of validated questionnaires were given to all participants at (a assessment, (b discharge, (c at a one-month, and (d at a 3-month follow-up visit. Results: Differences emerged between urban and rural treatment-seeking gamblers. While overall treatment outcomes were much the same at three months after treatment, rural gamblers appeared to respond more rapidly and to have sustained improvements over time. Conclusion: This study suggests that rural problem gamblers experience different levels of co-morbid anxiety and depression from their urban counterparts, but once in treatment appear to respond quicker. ACBT approach was found to be effective in treating rural gamblers and outcomes were maintained. Ensuring better availability and access to such treatment in rural areas is important. Nurses are in a position as the majority health professional in rural areas to provide such help.

2016-01-01

Cognitive Neuroscience Robotics is the first introductory book on this new interdisciplinary area. This book consists of two volumes, the first of which, Synthetic Approaches to Human Understanding, advances human understanding from a robotics or engineering point of view. The second, Analytic Approaches to Human Understanding, addresses related subjects in cognitive science and neuroscience. These two volumes are intended to complement each other in order to more comprehensively investigate human cognitive functions, to develop human-friendly information and robot technology (IRT) systems, and to understand what kind of beings we humans are. Volume B describes to what extent cognitive science and neuroscience have revealed the underlying mechanism of human cognition, and investigates how development of neural engineering and advances in other disciplines could lead to deep understanding of human cognition.

Anxiety and Threat-Related Attention: Cognitive-Motivational Framework and Treatment.

Research in experimental psychopathology and cognitive theories of anxiety highlight threat-related attention biases (ABs) and underpin the development of a computer-delivered treatment for anxiety disorders: attention-bias modification (ABM) training. Variable effects of ABM training on anxiety and ABs generate conflicting research recommendations, novel ABM training procedures, and theoretical controversy. This article summarises an updated cognitive-motivational framework, integrating proposals from cognitive models of anxiety and attention, as well as evidence of ABs. Interactions between motivational salience-driven and goal-directed influences on multiple cognitive processes (e.g., stimulus evaluation, inhibition, switching, orienting) underlie anxiety and the variable manifestations of ABs (orienting towards and away from threat; threat-distractor interference). This theoretical analysis also considers ABM training as cognitive skill training, describes a conceptual framework for evaluating/developing novel ABM training procedures, and complements network-based research on reciprocal anxiety-cognition relationships.

Full Text Available Background and Objectives: Addiction and its complications is one of the major problems in the world and various types of psychotherapy approaches are used for its treatment. Among these approaches, cognitive-behavioral therapies have been widely used for the treatment of addiction in recent decades. The aim of this study was to estimate the effect of cognitive-behavioral therapies on the treatment of addicts in Iran by systematic review and meta-analysis method. Methods: Meta-analysis method was used, without limitation, to investigate all internal databases as well as Medlib, Sid, Magiran, Google Scholar, PubMed, Scopuse, Iranmedex, and ISI. Finally, 12 out of 63 articles were entered into the meta-analysis. Meta-regression was used to investigate the heterogeneity of the studies. Results: In this study, 12 articles were investigated, which increased to 25 studies, including therapeutic approaches. In 6 studies, no significant difference was observed in the experimental group before and after intervention, and in the remaining 19 studies the difference was significant. Combination of the results of 25 studies and using a random effects model of meta-analysis showed that cognitive-behavioral therapy was effective in the treatment of addiction (p<0.001. The standardized effect size in the experimental group before and after cognitive-behavioral therapy, was estimated to be -2.08 and its 95% confidence interval was -1.57 to -2.58. The standardized effect size in control and experimental groups after cognitive-behavioral therapy was estimated 0.40 and its 95% confidence interval was 0.10 to 0.70. Conclusion: Given that cognitive-behavioral therapy is effective in reducing addiction and its symptoms, this method can be used as a common treatment of addiction.

Stress-related exhaustion has been linked to a pattern of selective cognitive impairments, mainly affecting executive functioning, attention and episodic memory. Little is known about potential treatments of these cognitive deficits. The purpose of this study was to evaluate the effects of a process-based cognitive training intervention, designed to target the specific cognitive impairments associated with stress-related exhaustion. To this end, patients diagnosed with exhaustion disorder (ED) were randomized to either a multimodal stress rehabilitation program with the addition of a process-based cognitive training intervention (training group, n = 27) or a treatment-as-usual control condition, consisting of multimodal stress rehabilitation with no additional training (control group, n = 32). Treatment effects were evaluated through an extensive cognitive test battery, assessing both near and far transfer effects, as well as self-report forms regarding subjective cognitive complaints and burnout levels. Results showed pronounced training-related improvements on the criterion updating task (p effects to updating (p = 0.01) and episodic memory (p = 0.04). Also, the trained group reported less subjective memory complaints (p = 0.02) and levels of burnout decreased for both groups, but more so for the trained group (p = 0.04), following the intervention. These findings suggest that process-based cognitive training may be a viable method to address the cognitive impairments associated with ED.

More than 85% of pediatric cancer cases and 95% of deaths occur in resource-poor countries that use less than 5% of the world's health resources. In the developed world, approximately 81% of children with cancer can be cured. Models applicable in the most resource-poor settings are needed to address global inequities in pediatric cancer treatment. Between 2006 and 2011, a cohort of children received cancer therapy using a new approach in rural Rwanda. Children were managed by a team of a Rwandan generalist doctor, Rwandan nurse case manager, Rwanda-based US-trained pediatrician, and US-based pediatric oncologist. Biopsies and staging studies were obtained in-country. Pathologic diagnoses were made at US or European laboratories. Rwanda-based clinicians and the pediatric oncologist jointly generated treatment plans by telephone and email. Treatment was provided to 24 patients. Diagnoses included lymphomas (n = 10), sarcomas (n = 9), leukemias (n = 2), and other malignancies (n = 3). Standard chemotherapy regimens included CHOP, ABVD, VA, COP/COMP, and actino-VAC. Thirteen patients were in remission at the completion of data collection. Two succumbed to treatment complications and nine had progressive disease. There were no patients who abandoned treatment. The mean overall survival was 31 months and mean disease-free survival was 18 months. These data suggest that chemotherapy can be administered with curative intent to a subset of cancer patients in this setting. This approach provides a platform for pediatric cancer care models, relying on local physicians collaborating with remote specialist consultants to deliver subspecialty care in resource-poor settings. © 2016 Wiley Periodicals, Inc.

Our study aimed to investigate the short-term effect of combination antiretroviral therapy (cART) on cognitive performance and functional and structural connectivity and their relationship to plasma levels of antiretroviral (ARV) drugs. Seventeen ARV treatment-naïve HIV-infected individuals (baseline mean CD4 cell count, 479 ± 48 cells/mm 3 ) were age matched with 17 HIV-uninfected individuals. All subjects underwent a detailed neurocognitive and functional assessment and magnetic resonance imaging. HIV-infected subjects were scanned before starting cART and 12 weeks after initiation of treatment. Uninfected subjects were assessed once at baseline. Functional connectivity (FC) was assessed within the default mode network while structural connectivity was assessed by voxel-wise analysis using tract-based spatial statistics (TBSS) and probabilistic tractography within the DMN. Tenofovir and emtricitabine blood concentration were measured at week 12 of cART. Prior to cART, HIV-infected individuals had significantly lower cognitive performance than control subjects as measured by the total Z-score from the neuropsychological tests assessing six cognitive domains (p = 0.020). After 12 weeks of cART treatment, there remained only a weak cognitive difference between HIV-infected and HIV-uninfected subjects (p = 0.057). Mean FC was lower in HIV-infected individuals compared with those uninfected (p = 0.008), but FC differences became non-significant after treatment (p = 0.197). There were no differences in DTI metrics between HIV-infected and HIV-uninfected individuals using the TBSS approach and limited evidence of decreased structural connectivity within the DMN in HIV-infected individuals. Tenofovir and emtricitabine plasma concentrations did not correlate with either cognitive performance or imaging metrics. Twelve weeks of cART improves cognitive performance and functional connectivity in ARV treatment-naïve HIV-infected individuals with relatively

General Systems Performance Theory (GSPT) was initially motivated by problems associated with quantifying different aspects of human performance. It has proved to be invaluable for measurement development and understanding quantitative relationships between human subsystem capacities and performance in complex tasks. It is now desired to bring focus to the application of GSPT to modeling of cognitive system performance. Previous studies involving two complex tasks (i.e., driving and performing laparoscopic surgery) and incorporating measures that are clearly related to cognitive performance (information processing speed and short-term memory capacity) were revisited. A GSPT-derived method of task analysis and performance prediction termed Nonlinear Causal Resource Analysis (NCRA) was employed to determine the demand on basic cognitive performance resources required to support different levels of complex task performance. This approach is presented as a means to determine a cognitive workload profile and the subsequent computation of a single number measure of cognitive workload (CW). Computation of CW may be a viable alternative to measuring it. Various possible "more basic" performance resources that contribute to cognitive system performance are discussed. It is concluded from this preliminary exploration that a GSPT-based approach can contribute to defining cognitive performance models that are useful for both individual subjects and specific groups (e.g., military pilots).

BACKGROUND: Chronic post-traumatic headache (CPTH) after mild head injury can be difficult to manage. Research is scarce and successful interventions are lacking.To evaluate the effect of a group-based Cognitive Behavioural Therapy (CBT) intervention in relation to headache, pain perception...... distress, and the overall experience of symptoms. The waiting-list group experienced no change in headache but, opposed to the treatment group, a significant decrease in somatic and cognitive symptoms indicating a spontaneous remission over time. CONCLUSIONS: Our primarily negative findings confirm...

Full Text Available Purpose: This study compared the effectiveness of group cognitive-behavioral therapy based on coping skills (CBT and methadone maintenance therapy (MMT in improvement of emotional regulation strategies and prevention of relapse. Method: The method of the present study was semi-experimental research design (pre-test-post-test with witness group. For sampling 45 substance abuse people who had referred to addiction treatment centers were selected and assigned to three groups of cognitive behavior therapy, methadone maintenance treatment and witness group randomly. The participants in all three groups completed the emotional intelligence questionnaire before and after the intervention. Data were analyzed by covariance method. Results: The results showed that cognitive-behavior therapy in comparison to methadone maintenance therapy and witness group led to significant improvement of emotional regulation in substance abusers, but there was no significant difference between the methadone maintenance treatment group and control group. Also, the rate of relapse in individuals who assigned to cognitive-behavior therapy group in comparison to methadone maintenance therapy and the witness group was significantly lower, but there was no significant difference between methadone therapy and witness. Conclusion: Cognitive-behavior therapy was an effective treatment that can change the cognitive and behavioral variables related to substance abuse, such as emotional regulation strategies. Thus, results suggested that drug abuse treatment programs must target these mediator variables.

THE HUMAN ACTIVITY AS AFFECTIVE-COGNITIVE UNIT: A HISTORIC-CULTURAL APPROACH

Directory of Open Access Journals (Sweden)

Lígia Márcia Martins

2017-01-01

Full Text Available This article puts in question the affectional-cognitive unit which sustains the human activity, with the purpose to light incorrectness of approaches which dichotomize reason and emotion. It asserts that such dissociations are founded in theorical-methodological principles which set bounds for explanations about the human psychism, so that the overcoming of referred dualisms puts on as a method matter. For making explicit that assertion, it resorted to Historic-Cultural Psychology, based on that it explains about the psychism as subjective image of objective reality, of Vygotskyan criticisms to Cartesian dualism and the need of a historic-cultural approach on emotion studies, intend to analyzing the human activity as a affective-cognitive unit and the imbricated relations that are waged, within it, among affections, emotions, feelings and thoughts. Once presented the interrelations between emotions and cognitions this exhibition argues that the concepts are necessary as a minimum unit of analysis both of thought and feelings.

Data mining approach to bipolar cognitive map development and decision analysis

Science.gov (United States)

Zhang, Wen-Ran

2002-03-01

A data mining approach to cognitive mapping is presented based on bipolar logic, bipolar relations, and bipolar clustering. It is shown that a correlation network derived from a database can be converted to a bipolar cognitive map (or bipolar relation). A transitive, symmetric, and reflexive bipolar relation (equilibrium relation) can be used to identify focal links in decision analysis. It can also be used to cluster a set of events or itemsets into three different clusters: coalition sets, conflict sets, and harmony sets. The coalition sets are positively correlated events or itemsets; each conflict set is a negatively correlated set of two coalition subsets; and a harmony set consists of events that are both negatively and positively correlated. A cognitive map and the clusters can then be used for online decision analysis. This approach combines knowledge discovery with the views of decision makers and provides an effective means for online analytical processing (OLAP) and online analytical mining (OLAM).

How Affectively-Based and Cognitively-Based Attitudes Drive Intergroup Behaviours: The Moderating Role of Affective-Cognitive Consistency

Zhou, Jie; Dovidio, John; Wang, Erping

2013-01-01

The moderating role of affective-cognitive consistency in the effects of affectively-based and cognitively-based attitudes on consummatory and instrumental behaviors was explored using two experimental studies in the intergroup context. Study 1 revealed that affectively-based attitudes were better predictors than cognitively-based attitudes regardless of affective-cognitive consistency for consummatory behaviors (e.g., undergraduates’ supportive behaviors toward government officials). Study 2, which investigated task groups’ supportive behaviors toward an immediate supervisory group, found that for these instrumental behaviors cognitively-based attitudes were better predictors than affectively-based attitudes only when affective-cognitive consistency was high. The present research also examined the mechanism by which affective-cognitive consistency moderates the relative roles of affectively-based and cognitively-based attitudes in attitude-behavior consistency. Results indicated that attitude-behavior consistency is eroded primarily because of the weaker relationship of affective or cognitive components to behaviors than to general attitudes. The reciprocal implications of research on attitudes and work on intergroup relations are considered. PMID:24244751

Treatment delivery factors (i.e., therapist adherence, therapist competence, and therapeutic alliance) are considered to be important for cognitive behavioral therapy (CBT) for panic disorder and agoraphobia (PD/AG). In the current study, four independent raters conducted process evaluations based on 168 two-hour videotapes of 84 patients with PD/AG treated with exposure-based CBT. Two raters evaluated patients' interpersonal behavior in Session 1. Two raters evaluated treatment delivery factors in Session 6, in which therapists provided the rationale for conducting exposure exercises. At the 6-month follow-up, therapists' adherence (r=0.54) and therapeutic alliance (r=0.31) were significant predictors of changes in agoraphobic avoidance behavior; therapist competence was not associated with treatment outcomes. Patients' interpersonal behavior in Session 1 was a significant predictor of the therapeutic alliance in Session 6 (r=0.17). The findings demonstrate that treatment delivery factors, particularly therapist adherence, are relevant to the long-term success of CBT for PD/AG. Copyright © 2016 Elsevier Ltd.

Davidson, Charlie A; Lesser, Rebecca; Parente, Lori T; Fiszdon, Joanna M

2018-03-01

Social cognition represents an important treatment target, closely linked to everyday social function. While a number of social cognitive interventions have recently been developed, measures used to evaluate these treatments are only beginning to receive psychometric scrutiny. Study goals were to replicate recently-published psychometrics for several social cognitive measures, and to provide information for additional social cognitive measures not included in recent reports. Forty-eight outpatients with psychotic-spectrum disorders completed measures of emotion perception, theory of mind, and attributional bias on two occasions, one month apart. Measures were tested for distributional characteristics, test-retest reliability, utility as a repeated measure, and relationship to symptoms and functioning. For a subgroup of participants, information about sensitivity to social cognitive treatment was also available. We replicated aspects of prior work, including largely favorable psychometric characteristics for the Bell-Lysaker Emotion Recognition Task, and promising but weaker characteristics for The Awareness of Social Inferences Test subscales and Reading the Mind in the Eyes Task. The Hinting Task had adequate test-retest statistics but a more pronounced ceiling effect. Ambiguous Intentions and Hostility Questionnaire data showed evidence of validity but were limited by inconsistency over time. Our results strongly support the Davos Assessment of Cognitive Biases Scale for future evaluation as a social cognitive treatment outcome measure. Its scores were adequately distributed, consistent over time, related to symptoms and functioning, and sensitive to treatment effects. Other relatively novel assessments of attributional bias and theory of mind showed some promise, although more work is needed. Published by Elsevier B.V.

Exploring Music-Based Rehabilitation for Parkinsonism through Embodied Cognitive Science

Science.gov (United States)

Schiavio, Andrea; Altenmüller, Eckart

2015-01-01

Recent embodied approaches in cognitive sciences emphasize the constitutive roles of bodies and environment in driving cognitive processes. Cognition is thus seen as a distributed system based on the continuous interaction of bodies, brains, and environment. These categories, moreover, do not relate only causally, through a sequential input–output network of computations; rather, they are dynamically enfolded in each other, being mutually implemented by the concrete patterns of actions adopted by the cognitive system. However, while this claim has been widely discussed across various disciplines, its relevance and potential beneficial applications for music therapy remain largely unexplored. With this in mind, we provide here an overview of the embodied approaches to cognition, discussing their main tenets through the lenses of music therapy. In doing so, we question established methodological and theoretical paradigms and identify possible novel strategies for intervention. In particular, we refer to the music-based rehabilitative protocols adopted for Parkinson’s disease patients. Indeed, in this context, it has recently been observed that music therapy not only affects movement-related skills but that it also contributes to stabilizing physiological functions and improving socio-affective behaviors. We argue that these phenomena involve previously unconsidered aspects of cognition and (motor) behavior, which are rooted in the action-perception cycle characterizing the whole living system.

Nanotechnology-Based Approach in Tuberculosis Treatment

Directory of Open Access Journals (Sweden)

Mohammad Nasiruddin

2017-01-01

Full Text Available Tuberculosis, commonly known as TB, is the second most fatal infectious disease after AIDS, caused by bacterium called Mycobacterium tuberculosis. Prolonged treatment, high pill burden, low compliance, and stiff administration schedules are factors that are responsible for emergence of MDR and XDR cases of tuberculosis. Till date, only BCG vaccine is available which is ineffective against adult pulmonary TB, which is the most common form of disease. Various unique antibodies have been developed to overcome drug resistance, reduce the treatment regimen, and elevate the compliance to treatment. Therefore, we need an effective and robust system to subdue technological drawbacks and improve the effectiveness of therapeutic drugs which still remains a major challenge for pharmaceutical technology. Nanoparticle-based ideology has shown convincing treatment and promising outcomes for chronic infectious diseases. Different types of nanocarriers have been evaluated as promising drug delivery systems for various administration routes. Controlled and sustained release of drugs is one of the advantages of nanoparticle-based antituberculosis drugs over free drug. It also reduces the dosage frequency and resolves the difficulty of low poor compliance. This paper reviews various nanotechnology-based therapies which can be used for the treatment of TB.

The goal of this study was to examine the impact of supplementing Trauma-focused Cognitive Behavioral Therapy (TF-CBT; Cohen et al., 2006) with evidence-based engagement strategies on foster parent and foster youth engagement in treatment, given challenges engaging foster parents in treatment. A randomized controlled trial of TF-CBT standard delivery compared to TF-CBT plus evidence-based engagement strategies was conducted with 47 children and adolescents in foster care and one of their foster parents. Attendance, engagement, and clinical outcomes were assessed 1 month into treatment, end of treatment, and 3 months post-treatment. Youth and foster parents who received TF-CBT plus evidence-based engagement strategies were more likely to be retained in treatment through four sessions and were less likely to drop out of treatment prematurely. The engagement strategies did not appear to have an effect on the number of canceled or no-show sessions or on treatment satisfaction. Clinical outcomes did not differ by study condition, but exploratory analyses suggest that youth had significant improvements with treatment. Strategies that specifically target engagement may hold promise for increasing access to evidence-based treatments and for increasing likelihood of treatment completion.

Towards a model-based cognitive neuroscience of stopping - a neuroimaging perspective.

Sebastian, Alexandra; Forstmann, Birte U; Matzke, Dora

2018-07-01

Our understanding of the neural correlates of response inhibition has greatly advanced over the last decade. Nevertheless the specific function of regions within this stopping network remains controversial. The traditional neuroimaging approach cannot capture many processes affecting stopping performance. Despite the shortcomings of the traditional neuroimaging approach and a great progress in mathematical and computational models of stopping, model-based cognitive neuroscience approaches in human neuroimaging studies are largely lacking. To foster model-based approaches to ultimately gain a deeper understanding of the neural signature of stopping, we outline the most prominent models of response inhibition and recent advances in the field. We highlight how a model-based approach in clinical samples has improved our understanding of altered cognitive functions in these disorders. Moreover, we show how linking evidence-accumulation models and neuroimaging data improves the identification of neural pathways involved in the stopping process and helps to delineate these from neural networks of related but distinct functions. In conclusion, adopting a model-based approach is indispensable to identifying the actual neural processes underlying stopping. Copyright © 2018 The Authors. Published by Elsevier Ltd..

2013-12-01

Efficacious treatments for seasonal affective disorder include light therapy and a seasonal affective disorder-tailored form of cognitive-behavioral therapy. Using data from a parent clinical trial, these secondary analyses examined the relationship between cognitive change over treatment with cognitive-behavioral therapy, light therapy, or combination treatment and mood outcomes the next winter. Sixty-nine participants were randomly assigned to 6-weeks of cognitive-behavioral therapy, light therapy, or combination treatment. Cognitive constructs (i.e., dysfunctional attitudes, negative automatic thoughts, and rumination) were assessed at pre- and post-treatment. Dysfunctional attitudes, negative automatic thoughts, and rumination improved over acute treatment, regardless of modality; however, in participants randomized to solo cognitive-behavioral therapy, a greater degree of improvement in dysfunctional attitudes and automatic thoughts was uniquely associated with less severe depressive symptoms the next winter. Change in maladaptive thoughts during acute treatment appears mechanistic of solo cognitive-behavioral therapy's enduring effects the next winter, but is simply a consequence of diminished depression in light therapy and combination treatment.

Industrial wastewaters containing biorefractory compounds like cyanide offer significant environmental problems attributed to the fact that the conventional methods have limited effectiveness and hence developing efficient treatment approaches is an important requirement. The present work investigates the use of novel treatment approach of ultrasound (US) combined with advanced oxidation techniques for the degradation of potassium ferrocyanide (KFC) for the first time. An ultrasonic bath equipped with longitudinal horn (1kW rated power and 25kHz frequency) has been used. The effect of initial pH (2-9) on the progress of degradation has been investigated initially and subsequently using the optimized pH, effect of addition of hydrogen peroxide (ratio of KFC:H 2 O 2 varied over the range of 1:0.5-1:5) and TiO 2 in the presence of H 2 O 2 (1:1 ratio by weight of TiO 2 ) as process intensifying approach has been studied. Combination of ultrasonic irradiation with ozone (O 3 ) (100-400mg/h) and ultraviolet irradiation (UV) has also been investigated. Use of combination of US with H 2 O 2, H 2 O 2 +TiO 2 and ozone resulted in extent of KFC degradation as 54.2%, 74.82% and 82.41% respectively. Combination of US with both UV and ozone was established to be the best approach yielding 92.47% degradation. The study also focused on establishing kinetic rate constants for all the treatment approaches which revealed that all the approaches followed first order kinetic mechanism with higher rate constants for the combination approaches. Overall, it has been conclusively established that ultrasound based combined treatment schemes are very effective for the treatment of KFC containing wastewaters. Copyright © 2017 Elsevier B.V.

2016-01-01

Cognitive Neuroscience Robotics is the first introductory book on this new interdisciplinary area. This book consists of two volumes, the first of which, Synthetic Approaches to Human Understanding, advances human understanding from a robotics or engineering point of view. The second, Analytic Approaches to Human Understanding, addresses related subjects in cognitive science and neuroscience. These two volumes are intended to complement each other in order to more comprehensively investigate human cognitive functions, to develop human-friendly information and robot technology (IRT) systems, and to understand what kind of beings we humans are. Volume A describes how human cognitive functions can be replicated in artificial systems such as robots, and investigates how artificial systems could acquire intelligent behaviors through interaction with others and their environment.

Cognitive development in introductory physics: A research-based approach to curriculum reform

Science.gov (United States)

Teodorescu, Raluca Elena

This project describes the research on a classification of physics problems in the context of introductory physics courses. This classification, called the Taxonomy of Introductory Physics Problems (TIPP), relates physics problems to the cognitive processes required to solve them. TIPP was created for designing and clarifying educational objectives, for developing assessments that can evaluate individual component processes of the problem-solving process, and for guiding curriculum design in introductory physics courses, specifically within the context of a "thinking-skills" curriculum. TIPP relies on the following resources: (1) cognitive research findings adopted by physics education research, (2) expert-novice research discoveries acknowledged by physics education research, (3) an educational psychology taxonomy for educational objectives, and (4) various collections of physics problems created by physics education researchers or developed by textbook authors. TIPP was used in the years 2006--2008 to reform the first semester of the introductory algebra-based physics course (called Phys 11) at The George Washington University. The reform sought to transform our curriculum into a "thinking-skills" curriculum that trades "breadth for depth" by focusing on fewer topics while targeting the students' cognitive development. We employed existing research on the physics problem-solving expert-novice behavior, cognitive science and behavioral science findings, and educational psychology recommendations. Our pedagogy relies on didactic constructs such as the GW-ACCESS problem-solving protocol, learning progressions and concept maps that we have developed and implemented in our introductory physics course. These tools were designed based on TIPP. Their purpose is: (1) to help students build local and global coherent knowledge structures, (2) to develop more context-independent problem-solving abilities, (3) to gain confidence in problem solving, and (4) to establish

Evidence suggests that testicular cancer (TC) and its treatment are associated with cognitive impairment. However, the underlying neural substrate and biological mechanisms are poorly understood. This study aimed to investigate changes in cognition and brain grey matter (GM) morphology in TC patients undergoing treatment, and to explore associations with immune markers, endocrine markers, and genotype. Sixty-five patients with stage I-III TC underwent assessment after surgery but prior to further treatment and again 6 months after. Twenty-two patients received chemotherapy (+CT), while 43 did not (-CT). Assessments included neuropsychological testing, whole-brain magnetic resonance imaging, and blood samples. Twenty-five healthy controls (HCs) underwent neuropsychological testing with a matching time interval. A regression-based approach was used to determine cognitive changes and longitudinal voxel-based morphometry (VBM) was performed to investigate changes in GM density in the TC groups. Compared with the HCs, both TC groups showed higher rates of cognitive decline (p < 0.05). A trend towards greater decline was observed in + CT (63.6 %) compared with -CT patients (39.5 %) (p = 0.07). VBM revealed widespread GM reductions in both TC groups, but a group-by-time interaction analysis revealed prefrontal reductions specific to the + CT group (p = 0.02), which were associated with poorer cognitive performance. Poorer cognitive performance was also associated with an increase in tumor necrosis factor alpha in + CT patients. Furthermore, an interaction effect was found between the APOE ε4 genotype and chemotherapy on cognitive performance with ε4 carriers performing significantly worse. These findings provide novel evidence of changes in cognition and brain morphology in TC patients undergoing treatment.

Behavioural and Cognitive-Behavioural Treatments of Parasomnias

Directory of Open Access Journals (Sweden)

Andrea Galbiati

2015-01-01

Full Text Available Parasomnias are unpleasant or undesirable behaviours or experiences that occur predominantly during or within close proximity to sleep. Pharmacological treatments of parasomnias are available, but their efficacy is established only for few disorders. Furthermore, most of these disorders tend spontaneously to remit with development. Nonpharmacological treatments therefore represent valid therapeutic choices. This paper reviews behavioural and cognitive-behavioural managements employed for parasomnias. Referring to the ICSD-3 nosology we consider, respectively, NREM parasomnias, REM parasomnias, and other parasomnias. Although the efficacy of some of these treatments is proved, in other cases their clinical evidence cannot be provided because of the small size of the samples. Due to the rarity of some parasomnias, further multicentric researches are needed in order to offer a more complete account of behavioural and cognitive-behavioural treatments efficacy.

Abstract Over the last decade, there has been a growing appreciation of the importance of identifying and treating cognitive impairment associated with bipolar disorder, since it persists in remission periods. Evidence indicates that neurocognitive dysfunction may significantly influence patients’ psychosocial outcomes. An ever-increasing body of research seeks to achieve a better understanding of potential moderators contributing to cognitive impairment in bipolar disorder in order to develop prevention strategies and effective treatments. This review provides an overview of the available data from studies examining treatments for cognitive dysfunction in bipolar disorder as well as potential novel treatments, from both pharmacological and psychological perspectives. All these data encourage the development of further studies to find effective strategies to prevent and treat cognitive impairment associated with bipolar disorder. These efforts may ultimately lead to an improvement of psychosocial functioning in these patients. PMID:28498954

Degenerative diseases are results of deterioration of cells and tissues with aging either by unhealthy lifestyle or normal senescence. The degenerative disease likely affects central nervous system and cardiovascular system to a great extent. Certain medications and therapies have emerged for the treatment of degenerative diseases, but in most cases bearing with poor solubility, lower bioavailability, drug resistance, and incapability to cross the blood-brain barrier (BBB). Hence, it has to be overcome with conventional treatment system; in this connection, nanotechnology has gained a great deal of interest in recent years. Moreover, nanotechnology and nanocarrier-based approach drug delivery system could revolutionize the treatment of degenerative diseases by faster absorption of drug, targeted interaction at specific site, and its release in a controlled manner into human body with minimal side effects. The core objective of this review is to customize and formulate therapeutically active molecules with specific site of action and without affecting other organs and tissues to obtain effective result in the improvement of quality of health. In addition, the review provides a concise insight into the recent developments and applications of nanotech and nanocarrier-based drug delivery for the treatment of various degenerative diseases.

Menopausal symptoms are common and may be particularly severe in younger women who undergo treatment-induced menopause. Medications to reduce menopausal symptoms are either contra-indicated or have bothersome side effects. Previous studies have demonstrated that face-to-face cognitive behavioral therapy (CBT) is effective in alleviating menopausal symptoms in women with breast cancer. However, compliance with face-to-face CBT programs can be problematic. A promising approach is to use the Internet to make this form of CBT more accessible and feasible for patients. This study is evaluating the efficacy and cost-effectiveness of an Internet-based CBT program, with or without therapist guidance, in alleviating or reducing the severity of menopausal symptoms. In a multicenter, randomized controlled trial we are evaluating the efficacy of two Internet-based CBT programs in alleviating or reducing the impact of menopausal symptoms, and particularly hot flushes and night sweats, in breast cancer survivors who have experienced a treatment-induced menopause. Secondary outcomes include sexual functioning, sleep quality, hot flush frequency, psychological distress, health-related quality of life and cost-effectiveness. We will recruit 248 women who will be randomized to either a therapist guided or a self-management version of the 6-week Internet-based CBT program, or to a usual care, waiting list control group. Self-administered questionnaires are completed at baseline (T0), and at 10 weeks (T1) and 24 weeks (T2) post-randomization. Internet-based CBT is a potentially useful treatment for reducing menopausal symptoms in breast cancer survivors. This study will provide evidence on the efficacy and cost-effectiveness of such an Internet-based CBT program, with or without therapist support. If demonstrated to be efficacious and cost-effective, the availability of such structured supportive intervention programs will be a welcome addition to standard medical treatment offered

There is no empirical basis for determining which seasonal affective disorder (SAD) patients are best suited for what type of treatment. Using data from a parent clinical trial comparing light therapy (LT), cognitive-behavioral therapy (CBT), and their combination (CBT + LT) for SAD, we constructed hierarchical linear regression models to explore baseline cognitive vulnerability constructs (i.e., dysfunctional attitudes, negative automatic thoughts, response styles) as prognostic and prescriptive factors of acute and next winter depression outcomes. Cognitive constructs did not predict or moderate acute treatment outcomes. Baseline dysfunctional attitudes and negative automatic thoughts were prescriptive of next winter treatment outcomes. Participants with higher baseline levels of dysfunctional attitudes and negative automatic thoughts had less severe depression the next winter if treated with CBT than if treated with LT. In addition, participants randomized to solo LT who scored at or above the sample mean on these cognitive measures at baseline had more severe depressive symptoms the next winter relative to those who scored below the mean. Baseline dysfunctional attitudes and negative automatic thoughts did not predict treatment outcomes in participants assigned to solo CBT or CBT + LT. Therefore, SAD patients with extremely rigid cognitions did not fare as well in the subsequent winter if treated initially with solo LT. Such patients may be better suited for initial treatment with CBT, which directly targets cognitive vulnerability processes. Copyright © 2013 Elsevier Ltd. All rights reserved.

Bulzacka, E; Lavault, S; Pelissolo, A; Bagnis Isnard, C

2018-02-01

Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction. The effectiveness of these programs is well documented in the field of emotional response regulation in depression (relapse prevention), anxiety disorders, obsessive-compulsive disorder or eating disorders. Furthermore, converging lines of evidence support the hypothesis that mindfulness practice improves cognition, especially the ability to sustain attention and think in a more flexible manner. Nevertheless, formal rehabilitation programs targeting cognitive disturbances resulting from psychiatric (depression, disorder bipolar, schizophrenia) or neurologic conditions (brain injury, dementia) seldom rely on MBI principles. This review of literature aims at discussing possible links between MBI and clinical neuropsychology. We conducted a review of literature using electronic databases up to December 2016, screening studies with variants of the keywords ("Mindfulness", "MBI", "MBSR", "Meditation") OR/AND ("Cognition", "Attention", "Executive function", "Memory", "Learning") RESULTS: In the first part, we describe key concepts of the neuropsychology of attention in the light of Posner's model of attention control. We also underline the potential scope of different therapeutic contexts where disturbances of attention may be clinically relevant. Second, we review the efficacy of MBI in the field of cognition (thinking disturbances, attention biases, memory and executive processes impairment or low metacognitive abilities

Walczyk, Jeffrey J.; Igou, Frank P.; Dixon, Alexa P.; Tcholakian, Talar

2013-01-01

This article critically reviews techniques and theories relevant to the emerging field of “lie detection by inducing cognitive load selectively on liars.” To help these techniques benefit from past mistakes, we start with a summary of the polygraph-based Controlled Question Technique (CQT) and the major criticisms of it made by the National Research Council (2003), including that it not based on a validated theory and administration procedures have not been standardized. Lessons from the more successful Guilty Knowledge Test are also considered. The critical review that follows starts with the presentation of models and theories offering insights for cognitive lie detection that can undergird theoretically load-inducing approaches. This is followed by evaluation of specific research-based, load-inducing proposals, especially for their susceptibility to rehearsal and other countermeasures. To help organize these proposals and suggest new direction for innovation and refinement, a theoretical taxonomy is presented based on the type of cognitive load induced in examinees (intrinsic or extraneous) and how open-ended the responses to test items are. Finally, four recommendations are proffered that can help researchers and practitioners to avert the corresponding mistakes with the CQT and yield new, valid cognitive lie detection technologies.

. That is, training does not cause cognitive transfer and thus does not constitute “brain training” or “brain exercise” of any clinical relevance. A larger study found more promising results for a suggestion-based treatment in a hypnotic procedure. Patients improved to above population average in a matter...... of 4-8 hours, making this by far the most effective treatment compared to computer-based training, physical exercise, phamaceuticals, meditation, and attention process training. The contrast between computer-based methods and the hypnotic suggestion treatment may be reflect a more general discrepancy...

Does the cognitive reflection test measure cognitive reflection? A mathematical modeling approach.

Science.gov (United States)

Campitelli, Guillermo; Gerrans, Paul

2014-04-01

We used a mathematical modeling approach, based on a sample of 2,019 participants, to better understand what the cognitive reflection test (CRT; Frederick In Journal of Economic Perspectives, 19, 25-42, 2005) measures. This test, which is typically completed in less than 10 min, contains three problems and aims to measure the ability or disposition to resist reporting the response that first comes to mind. However, since the test contains three mathematically based problems, it is possible that the test only measures mathematical abilities, and not cognitive reflection. We found that the models that included an inhibition parameter (i.e., the probability of inhibiting an intuitive response), as well as a mathematical parameter (i.e., the probability of using an adequate mathematical procedure), fitted the data better than a model that only included a mathematical parameter. We also found that the inhibition parameter in males is best explained by both rational thinking ability and the disposition toward actively open-minded thinking, whereas in females this parameter was better explained by rational thinking only. With these findings, this study contributes to the understanding of the processes involved in solving the CRT, and will be particularly useful for researchers who are considering using this test in their research.

Dural arteriovenous fistulae (DAVF) occasionally lead to cognitive disorders whose reversibility after DAVF treatment remains unclear. We studied changes on pre- and post-treatment magnetic resonance imaging (MRI) and single photon emission computed tomography (SPECT) scans in ten patients with cognitive disorder due to DAVF. We studied the symptoms, pre- and post-treatment MRI scans, SPECT findings, and mini-mental state examination (MMSE) and treatment results in ten patients with cognitive disorder due to DAVF. They were divided into two groups; the post-treatment MMSE score exceeded 25 points in group 1 (n = 6) and was lower than 24 points in group 2 (n = 4). In the six group 1 patients, pretreatment diffusion-weighted images (DWI) showed hyperintense areas, and SPECT scans demonstrated the preservation of vasoreactivity after acetazolamide challenge. In the four group 2 patients, pretreatment SPECT demonstrated hypoperfusion areas that coincided with the hyperintense areas seen on DWI; there were areas with marked disturbance in vasoreactivity. The post-treatment MMSE score in groups 1 and 2 improved by 13.7 ± 2.4 and 3.8 ± 1.0 points, respectively; the difference was significant at p < 0.01. In patients with cognitive disorder due to DAVF, the preservation of vasoreactivity on SPECT after acetazolamide challenge indicates that their cognitive disorder may be reversible by DAVF treatment.

Intelligent cognitive radio jamming - a game-theoretical approach

Dabcevic, Kresimir; Betancourt, Alejandro; Marcenaro, Lucio; Regazzoni, Carlo S.

2014-12-01

Cognitive radio (CR) promises to be a solution for the spectrum underutilization problems. However, security issues pertaining to cognitive radio technology are still an understudied topic. One of the prevailing such issues are intelligent radio frequency (RF) jamming attacks, where adversaries are able to exploit on-the-fly reconfigurability potentials and learning mechanisms of cognitive radios in order to devise and deploy advanced jamming tactics. In this paper, we use a game-theoretical approach to analyze jamming/anti-jamming behavior between cognitive radio systems. A non-zero-sum game with incomplete information on an opponent's strategy and payoff is modelled as an extension of Markov decision process (MDP). Learning algorithms based on adaptive payoff play and fictitious play are considered. A combination of frequency hopping and power alteration is deployed as an anti-jamming scheme. A real-life software-defined radio (SDR) platform is used in order to perform measurements useful for quantifying the jamming impacts, as well as to infer relevant hardware-related properties. Results of these measurements are then used as parameters for the modelled jamming/anti-jamming game and are compared to the Nash equilibrium of the game. Simulation results indicate, among other, the benefit provided to the jammer when it is employed with the spectrum sensing algorithm in proactive frequency hopping and power alteration schemes.

, -0·22 to 0·83). At 12-month follow-up, the mean gain in BMI had risen further (1·64 kg/m(2), 1·30 kg/m(2), and 1·22 kg/m(2), respectively), but no differences between groups were recorded (0·10, -0·56 to 0·76; 0·25, -0·45 to 0·95; 0·15, -0·54 to 0·83, respectively). No serious adverse events attributable to weight loss or trial participation were recorded. Optimised treatment as usual, combining psychotherapy and structured care from a family doctor, should be regarded as solid baseline treatment for adult outpatients with anorexia nervosa. Focal psychodynamic therapy proved advantageous in terms of recovery at 12-month follow-up, and enhanced cognitive behaviour therapy was more effective with respect to speed of weight gain and improvements in eating disorder psychopathology. Long-term outcome data will be helpful to further adapt and improve these novel manual-based treatment approaches.

Cognitive behavioural group treatment for social anxiety in schizophrenia.

Science.gov (United States)

Kingsep, Patrick; Nathan, Paula; Castle, David

2003-09-01

Anxiety symptoms reported by individuals with schizophrenia have been traditionally seen as symptoms associated with the principal disorder and therefore not requiring special attention. The primary aim of this paper is to therapeutically target social anxiety symptoms in individuals with schizophrenia in order to determine the effectiveness of the cognitive behavioural group treatment model as an intervention for social anxiety in this participant group. Thirty-three individuals with schizophrenia and co-morbid social anxiety were allocated to a group-based cognitive behaviour (CBGT) intervention or waitlist control (WLC). Baseline, completion and follow-up ratings consist of measures of social anxiety: the Brief Social Phobia Scale (BSPS), Brief Fear of Negative Evaluation scale (BFNE) and the Social Interaction Anxiety Scale (SIAS); measures of general psychopathology: the Calgary Depression Scale for Schizophrenia (CDSS) and Global Severity Index (GSI) from the Brief Symptom Inventory (BSI); and the Quality of Life, Enjoyment and Satisfaction Questionnaire (QLESQ). Pre- and post-treatment measures were subjected to statistical evaluation. All outcome measures displayed statistical improvement in the intervention group compared with no change in the control group. These treatment gains were maintained at follow-up. CBGT for social anxiety in schizophrenia was demonstrated to be effective as an adjunctive treatment for this population.

Aguilera, Adrian; Garza, Monica J; Muñoz, Ricardo F

2010-08-01

The authors applied cognitive-behavioral therapy (CBT) for depression using the Healthy Management of Reality treatment manual. This 16-week group treatment comprised four 4-week modules: thoughts (cognitive restructuring), activities (behavioral activation), people (interpersonal skills training), and health (addresses physical health and depression). They illustrated the use of the culture-sensitive treatment manuals by way of the member characteristics and clinical process of a Spanish-language CBT group for depression. They highlighted the challenges and satisfactions of working with a Spanish-speaking population in the public sector, and focused on how culture and socioeconomic status influence patients, and how to adapt treatment to these factors. Last, they demonstrated how technological advances integrate with culture-sensitive, evidence-based treatments to better serve this population and reduce disparities.

To examine the association between long-term adherence to the Dietary Approaches to Stop Hypertension (DASH) diet with cognitive function and decline in older American women. Prospective cohort study. The Nurses' Health Study, a cohort of registered nurses residing in 11 US states. A total of 16,144 women from the Nurses' Health Study, aged ≥70 years, who underwent cognitive testing a total of 4 times by telephone from 1995 to 2001 (baseline), with multiple dietary assessments between 1984 and the first cognitive examination. DASH adherence for each individual was based on scoring of intakes of 9 nutrient or food components. Long-term DASH adherence was calculated as the average DASH adherence score from up to 5 repeated measures of diet. Primary outcomes were cognitive function calculated as the average scores of the 4 repeated measures, as well as cognitive change of the Telephone Interview for Cognitive Status score and composite scores of global cognition and verbal memory. Greater adherence to long-term DASH score was associated with better average cognitive function, irrespective of apolipoprotein E ε4 allele status [multivariable-adjusted differences in mean z-scores between extreme DASH quintiles = 0.04 (95% confidence interval, CI 0.01-0.07), P trend = .009 for global cognition; 0.04 (95% CI 0.01-0.07), P trend = .002 for verbal memory and 0.16 (95% CI 0.03-0.29), and P trend = .03 for Telephone Interview for Cognitive Status, P interaction >0.24]. These differences were equivalent to being 1 year younger in age. Adherence to the DASH score was not associated with change in cognitive function over 6 years. Our findings in the largest cohort on dietary patterns and cognitive function to date indicate that long-term adherence to the DASH diet is important to maintain cognitive function at older ages.

The question of ritual: a cognitive approach

Directory of Open Access Journals (Sweden)

Jesper Sørensen

2003-01-01

Full Text Available Why does ritual continue to be an issue in religious studies and in anthropology? In this paper the author proposes a cognitive approach to rituals, focusing those aspects of rituals that are distinct from other types of actions, together with what cognitive responses these differences provoke. It will be argued that rituals violate basic causal assumptions and by doing so, trigger off cognitive processes in order to ascribe purpose and meaning to the action. In conclusion, this will be related to findings in ethology and evolutionary theory, arguing that ritual as a behavioural category plays an important role in the formation of symbolic thinking.

Adolescent and young adult cancer (AYAC) survivors show an elevated risk of distress. Targeted psychosocial interventions for this distinct population are needed. This study examined the potential efficacy of a mindfulness-based intervention (MBI) to alleviate emotional distress and improve quality of life (QoL) in AYAC survivors. Participants were 16 AYAC survivors, aged 14-24, who had completed acute medical treatment. A two-baseline (8 and 1 week before the intervention), post- (1 week after the intervention) and 3 months follow-up within-subjects design was used. Each participant completed two baseline assessments, followed by an 8-week MBI. The primary outcome variables were emotional distress and QoL. Secondary outcomes were cognitive vulnerability factors and mindfulness skills. Multilevel modeling showed (1) a significant reduction in emotional distress and improvement in QoL at 3 months of follow-up, (2) a significant reduction in negative attitudes toward self (i.e., a cognitive vulnerability factor), and (3) a significant improvement in mindfulness skills. MBI is a promising approach that is used to treat emotional distress and to improve QoL in AYAC survivors. Further research using randomized controlled trials is needed to generalize these findings.

Towards a heterarchical approach to biology and cognition.

Science.gov (United States)

Bruni, Luis Emilio; Giorgi, Franco

2015-12-01

In this article we challenge the pervasive notion of hierarchy in biological and cognitive systems and delineate the basis for a complementary heterarchical approach starting from the seminal ideas of Warren McCullock and Gregory Bateson. We intend these considerations as a contribution to the different scientific disciplines working towards a multilevel integrative perspective of biological and cognitive processes, such as systems and integrative biology and neuroscience, social and cultural neuroscience, social signal transduction and psychoneuroimmunology, for instance. We argue that structures and substrates are by necessity organized hierarchically, while communication processes - and their embeddedness - are rather organized heterarchically. Before getting into the implications of the heterarchical approach and its congeniality with the semiotic perspective to biology and cognition, we introduce a set of notions and concepts in order to advance a framework that considers the heterarchical embeddedness of different layers of physiological, behavioral, affective, cognitive, technological and socio-cultural levels implicit in networks of interacting minds, considering the dynamic complementarity of bottom-up and top-down causal links. This should contribute to account for the integration, interpretation and response to complex aggregates of information at different levels of organization in a developmental context. We illustrate the dialectical nature of embedded heterarchical processes by addressing the simultaneity and circularity of cognition and volition, and how such dialectics can be present in primitive instances of proto-cognition and proto-volition, giving rise to our claim that subjectivity and semiotic freedom are scalar properties. We collate the framework with recent empirical systemic approaches to biology and integrative neuroscience, and conclude with a reflection on its implications to the understanding of the emergence of pathological

Full Text Available Background: Procrastination affects a large number of individuals and is associated with significant mental health problems. Despite the deleterious consequences individuals afflicted with procrastination have to bear, there is a surprising paucity of well-researched treatments for procrastination. To fill this gap, this study evaluated the efficacy of an easy-to-use smartphone-based treatment for procrastination. Method: N=31 individuals with heightened procrastination scores were randomly assigned to a blended smartphone-based intervention including two brief group counseling sessions and 14days of training with the mindtastic procrastination app (MT-PRO, or to a waitlist condition. MT-PRO fosters the approach of functional and the avoidance of dysfunctional behavior by systematically utilizing techniques derived from cognitive bias modification approaches, gamification principles, and operant conditioning. Primary outcome was the course of procrastination symptom severity as assessed with the General Procrastination Questionnaire. Results: Participating in the smartphone-based treatment was associated with a significantly greater reduction of procrastination than was participating in the control condition (η2=.15. Conclusion: A smartphone-based intervention may be an effective treatment for procrastination. Future research should use larger samples and directly compare the efficacy of smartphone-based interventions and traditional interventions for procrastination.

A Transdiagnostic Minority Stress Treatment Approach for Gay and Bisexual Men’s Syndemic Health Conditions

Pachankis, John E.

2015-01-01

Developing and deploying separate treatments for separate conditions seems ill-suited to intervening upon the co-occurring, and possibly functionally similar, psychosocial conditions facing gay and bisexual men. This article argues for the need to create transdiagnostic interventions that reduce multiple syndemic conditions facing gay and bisexual men at the level of their shared source in minority stress pathways. This article first reviews psychosocial syndemic conditions affecting gay and bisexual men, then suggests pathways that might link minority stress to psychosocial syndemics based on recent advancements in emotion science, psychiatric nosology, and cognitive-affective neuroscience, and finally suggests cross-cutting psychosocial treatment principles to reduce minority stress–syndemic pathways among gay and bisexual men. Because minority stress serves as a common basis of all psychosocial syndemic conditions reviewed here, locating the pathways through which minority stress generates psychosocial syndemics and employing overarching treatment principles capable of simultaneously alleviating these pathways will ultimately create a transdiagnostic approach to improving gay and bisexual men’s health. Clinical research and training approaches are suggested to further validate the pathways suggested here, establish the efficacy of treatment approaches tied to those pathways, and generate effective methods for disseminating a transdiagnostic minority stress treatment approach for gay and bisexual men’s psychosocial syndemic health.

Over the last decade, there has been a growing appreciation of the importance of identifying and treating cognitive impairment associated with bipolar disorder, since it persists in remission periods. Evidence indicates that neurocognitive dysfunction may significantly influence patients' psychosocial outcomes. An ever-increasing body of research seeks to achieve a better understanding of potential moderators contributing to cognitive impairment in bipolar disorder in order to develop prevention strategies and effective treatments. This review provides an overview of the available data from studies examining treatments for cognitive dysfunction in bipolar disorder as well as potential novel treatments, from both pharmacological and psychological perspectives. All these data encourage the development of further studies to find effective strategies to prevent and treat cognitive impairment associated with bipolar disorder. These efforts may ultimately lead to an improvement of psychosocial functioning in these patients. © The Author 2017. Published by Oxford University Press on behalf of CINP.

On finding the C in CBT: the challenges of applying gambling-related cognitive approaches to video-gaming.

Science.gov (United States)

Delfabbro, Paul; King, Daniel

2015-03-01

Many similarities have been drawn between the activities of gambling and video-gaming. Both are repetitive activities with intermittent reinforcement, decision-making opportunities, and elements of risk-taking. As a result, it might be tempting to believe that cognitive strategies that are used to treat problem gambling might also be applied to problematic video gaming. In this paper, we argue that many cognitive approaches to gambling that typically involve a focus on erroneous beliefs about probabilities and randomness are not readily applicable to video gaming. Instead, we encourage a focus on other clusters of cognitions that relate to: (a) the salience and over-valuing of gaming rewards, experiences, and identities, (b) maladaptive and inflexible rules about behaviour, (c) the use of video-gaming to maintain self-esteem, and (d) video-gaming for social status and recognition. This theoretical discussion is advanced as a starting point for the development of more refined cognitive treatment approaches for problematic video gaming.

2012-01-01

Full Text Available Objective. The effectiveness of an individualized and everyday approach to cognitive rehabilitation for schizophrenia was examined in a case study. Method. After cognitive and functional assessment, concrete objectives were targeted for the person’s everyday complaints. Strategies were constructed based on an analysis of the cognitive profile, daily life functioning, and processes involved in activities. They included a memory strategy for reading, a diary to compensate memory difficulties, and working memory exercises to improve immediate processing of information when reading and following conversations. Efficacy was assessed with outcome measures. Results. The program had beneficial effects on the person’s cognitive and everyday functioning, which persisted at a 3-year follow-up. Conclusion. Findings provide suggestive evidence that an individualized and everyday approach may be a useful alternative in order to obtain a meaningfully lasting transfer of training to daily life, compared to the nomothetic ones which dominate the field.

Diagnosis, treatment, and rehabilitation in patients with dizziness and cognitive impairment

L. M. Antonenko

2017-01-01

Full Text Available Complaints of dizziness and instability are the common reason for seeking a neurologist's advice at an outpatient visit and can be the frequent reason for emergency hospitalization.Difficulty in diagnosing the causes of dizziness and instability is due to a diversity of diseases manifested by these symptoms. The list of etiological factors includes peripheral and central vestibular lesions and unrelated nervous system diseases. In a number of cases, dizziness and instability are concurrent with cognitive impairment. Complaints of poor concentration and memory, dizziness and instability can often be associated with brain degenerative and/or vascular lesions, as well as with pathological mood changes and anxiety disorder.The diagnosis of these diseases requires neurovestibular examination, cognitive testing, and assessment of the emotional status of patients. Early detection of the causes of dizziness and memory disorders ensures better treatment results. There are different approaches to therapy for dizziness and cognitive impairment: drug and non-drug correction techniques (vestibular rehabilitation and cognitive training. Biofeedback procedures were shown to be highly effective.The effect of tanakan in treating patients with involvement of the peripheral vestibular system and brain structures is discussed

The Application of Cognitive Diagnostic Approaches via Neural Network Analysis of Serious Educational Games

Science.gov (United States)

Lamb, Richard L.

Serious Educational Games (SEGs) have been a topic of increased popularity within the educational realm since the early millennia. SEGs are generalized form of Serious Games to mean games for purposes other than entertainment but, that also specifically include training, educational purpose and pedagogy within their design. This rise in popularity (for SEGs) has occurred at a time when school systems have increased the type, number, and presentations of student achievement tests for decision-making purposes. These tests often task the form of end of course (year) tests and periodic benchmark testing. As the use of these tests, has increased policymakers have suggested their use as a measure for teacher accountability. The change in testing resulted from a push by school districts and policy makers at various component levels for a data-driven decision-making (D3M) approach. With the data-driven decision making approaches by school districts, there has been an increased focus on the measurement and assessment of student content knowledge with little focus on the contributing factors and cognitive attributes within learning that cross multiple-content areas. One-way to increase the focus on these aspects of learning (factors and attributes) that are additional to content learning is through assessments based in cognitive diagnostics. Cognitive diagnostics are a family of methodological approaches in which tasks tie to specific cognitive attributes for analytical purposes. This study explores data derived from computer data logging (n=158,000) in an observational design, using traditional statistical techniques such as clustering (exploratory and confirmatory), item response theory and through data mining techniques such as artificial neural network analysis. From these analyses, a model of student learning emerges illustrating student thinking and learning while engaged in SEG Design. This study seeks to use cognitive diagnostic type approaches to measure student

The Influence of Frontal Lobe Tumors and Surgical Treatment on Advanced Cognitive Functions.

2016-07-01

Brain cognitive functions affect patient quality of life. The frontal lobe plays a crucial role in advanced cognitive functions, including executive function, meta-cognition, decision-making, memory, emotion, and language. Therefore, frontal tumors can lead to serious cognitive impairments. Currently, neurosurgical treatment is the primary method to treat brain tumors; however, the effects of the surgical treatments are difficult to predict or control. The treatment may both resolve the effects of the tumor to improve cognitive function or cause permanent disabilities resulting from damage to healthy functional brain tissue. Previous studies have focused on the influence of frontal lesions and surgical treatments on patient cognitive function. Here, we review cognitive impairment caused by frontal lobe brain tumors.

The main aim of the study was to investigate the effectiveness of two psychotherapeutic approaches, cognitive behavioral therapy (CBT) and a complementary medicine method Reiki, in reducing depression scores in adolescents. We recruited 188 adolescent patients who were 12-17 years old. Participants were randomly assigned to CBT, Reiki or wait-list. Depression scores were assessed before and after the 12 week interventions or wait-list. CBT showed a significantly greater decrease in Child Depression Inventory (CDI) scores across treatment than both Reiki (peffect for Reiki than did female participants. Both CBT and Reiki were effective in reducing the symptoms of depression over the treatment period, with effect for CBT greater than Reiki. These findings highlight the importance of early intervention for treatment of depression using both cognitive and complementary medicine approaches. However, research that tests complementary therapies over a follow-up period and against a placebo treatment is required. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Canine separation-related problems (SRP) (also described as "separation anxiety" or "separation distress") are among the most common behavioural complaints of dog owners. Treatment with psychoactive medication in parallel with a behaviour modification plan is well documented in the literature, but it is unknown if this is associated with an improvement in underlying affective state (emotion and mood) or simply an inhibition of the behaviour. Cognitive judgement bias tasks have been proposed as a method for assessing underlying affective state and so we used this approach to identify if any change in clinical signs during treatment was associated with a consistent change in cognitive bias (affective state). Five dogs showing signs of SRP (vocalising - e.g. barking, howling-, destruction of property, and toileting - urination or defecation- when alone) were treated with fluoxetine chewable tablets (Reconcile™) and set on a standard behaviour modification plan for two months. Questionnaires and interviews of the owners were used to monitor the clinical progress of the dogs. Subjects were also evaluated using a spatial cognitive bias test to infer changes in underlying affect prior to, and during, treatment. Concurrently, seven other dogs without signs of SRP were tested in the same way to act as controls. Furthermore, possible correlations between cognitive bias and clinical measures were also assessed for dogs with SRP. Prior to treatment, the dogs with SRP responded to ambiguous positions in the cognitive bias test negatively (i.e. with slower running speeds) compared to control dogs (p 0.05). Questionnaire based clinical measures were significantly correlated among themselves and with performance in the cognitive bias test. These results demonstrate for the first time that the clinical treatment of a negative affective state and associated behaviours in a non-human species can produce a shift in cognitive bias. These findings demonstrate how the outcome of an

Full Text Available Several treatment evaluations have highlighted the effectiveness of cognitive-behavioural programmes with both youth and adult offenders. This paper describes the application and assessment of a cognitive-behavioural treatment (adapted to Spanish from Ross and Fabiano’s Reasoning & Rehabilitation Programme with juvenile offenders serving community orders in an educational measure called in Spanish ‘libertad vigilada’ (similar to parole. The intervention comprised six different therapeutic components: self-control, cognitive restructuring, problem solving, social skills/assertiveness, values/empathy, and relapse prevention. Treatment effectiveness was tested using a quasi-experimental design involving two groups and pre/post evaluation. The results show that the programme was effective (with low to moderate effect sizes in improving participants’ social skills and self-esteem, as well as in reducing their aggressiveness. However, the intervention had no positive influence on empathy, cognitive distortions or impulsiveness. These results are in line with those of many other correctional studies, in which the treatment applied had a significant but partial effect on participants.

Alcohol-related cognitive impairments are largely underestimated in clinical practice, even though they could limit the benefit of alcohol treatment and hamper the patient's ability to remain abstinent or to respect his/her therapeutic contract. These neuropsychological deficits can impact the management of patients well before the development of the well-known Korsakoff's syndrome. Indeed, even in the absence of ostensible neurological complications, excessive and chronic alcohol consumption results in damage of brain structure and function. The frontocerebellar circuit and the circuit of Papez, respectively involved in motor and executive abilities and episodic memory, are mainly affected. Those brain dysfunctions are associated with neuropsychological deficits, including deficits of executive functions, episodic memory, social cognition, as well as visuospatial and motor abilities. Such cognitive disorders can interfere with the motivation process to abandon maladjusted drinking behavior in favor of a healthier lifestyle (such as abstinence or controlled alcohol consumption). They can also limit the patient's capacity to fully benefit from treatment (notably psychoeducation and cognitive-behavioural treatments) currently widely proposed in French Addiction departments. In addition, they may contribute to relapse which is multi-determinated. A neuropsychological assessment appears therefore crucial to take relevant clinical decisions. However, very few addiction departments have the human and financial resources to conduct an extensive neuropsychological examination of all patients with alcohol dependence. Some brief screening tools can be used, notably the MOntreal Cognitive Assessment and the Brief Evaluation of Alcohol-Related Neuropsychological Impairments, which has been especially designed to assess cognitive and motor deficits in alcoholism. These tools can be used by non-psychologist clinicians to detect alcohol-related cognitive deficits, which require

In order to benefit from the highly conformal irradiation of tumors in ion radiotherapy, sophisticated treatment planning and simulation are required. The purpose of this study was to investigate the potential of MRI for ion radiotherapy treatment plan simulation and adaptation using a classification-based approach. Firstly, a voxelwise tissue classification was applied to derive pseudo CT numbers from MR images using up to 8 contrasts. Appropriate MR sequences and parameters were evaluated in cross-validation studies of three phantoms. Secondly, ion radiotherapy treatment plans were optimized using both MRI-based pseudo CT and reference CT and recalculated on reference CT. Finally, a target shift was simulated and a treatment plan adapted to the shift was optimized on a pseudo CT and compared to reference CT optimizations without plan adaptation. The derivation of pseudo CT values led to mean absolute errors in the range of 81 - 95 HU. Most significant deviations appeared at borders between air and different tissue classes and originated from partial volume effects. Simulations of ion radiotherapy treatment plans using pseudo CT for optimization revealed only small underdosages in distal regions of a target volume with deviations of the mean dose of PTV between 1.4 - 3.1% compared to reference CT optimizations. A plan adapted to the target volume shift and optimized on the pseudo CT exhibited a comparable target dose coverage as a non-adapted plan optimized on a reference CT. We were able to show that a MRI-based derivation of pseudo CT values using a purely statistical classification approach is feasible although no physical relationship exists. Large errors appeared at compact bone classes and came from an imperfect distinction of bones and other tissue types in MRI. In simulations of treatment plans, it was demonstrated that these deviations are comparable to uncertainties of a target volume shift of 2 mm in two directions indicating that especially

This study examined the effectiveness of manualized cognitive therapy (mCT) following the Clark-Wells approach versus non-manualized cognitive-behavioral treatment-as-usual (CBTAU) for social anxiety disorder (SAD) in routine practice. Forty-eight private practitioners were recruited within a multi-center trial and either received training in manualized CT for SAD or no such training. Practitioners treated 162 patients with SAD in routine practice (N = 107 completers, n = 57 for mCT, n = 50 for CBTAU). Social anxiety symptoms (Liebowitz Social Anxiety Scale; LSAS) and secondary measures were assessed before treatment, at treatment-hour 8, 15, and 25, at end of treatment, as well as 6 and 12 months after treatment. Patients in both groups showed significant reductions of SAD severity after treatment (d = 1.91 [mCT] and d = 1.80 [CBTAU], within-group effect sizes, intent-to-treat analyses, LSAS observer ratings), which remained stable at follow-up. There were no differences between groups in terms of symptom reduction and treatment duration. The present trial confirms the high effectiveness of CBTAU and mCT for SAD when practitioners conduct the treatments in routine practice. Additional training in the CT manual did not result in significant between-group effects on therapy outcome. Explanations for this unexpected result are discussed. Copyright © 2017 Elsevier Ltd.

The treatment of an unruptured intracranial aneurysm (UIA) is not free of morbidity and mortality, and the decision is made by weighing the risks of treatment complications against the risk of aneurysm rupture. This meta-analysis quantitatively analyzed the literature on the effects of UIA treatment on cognition. MEDLINE, Embase, and PsycInfo were systematically searched for studies that reported on the cognitive status of UIA patients before and after aneurysm treatment. The search was restricted to prospective cohort and case-control studies published between January 1, 1998, and January 1, 2013. The analyses focused on the effect of treatment on general cognitive functioning, with an emphasis on 4 specific cognitive domains: executive functions, verbal and visual memory, and visuospatial functions. Eight studies, with a total of 281 patients, were included in the meta-analysis. Treatment did not affect general cognitive functioning (effect size [ES] -0.22 [95% CI -0.78 to 0.34]). Executive functions and verbal memory domains trended toward posttreatment impairment (ES -0.46 [95% CI -0.93 to 0.01] and ES -0.31 [95% CI -1.24 to 0.61]), and performance of visual memory tasks trended toward posttreatment improvement (ES 1.48 [95% CI -0.36 to 3.31]). Lastly, treatment did not significantly affect visuospatial functions (ES -0.08 [95% CI -0.30 to 0.45]). The treatment of an UIA does not seem to affect long-term cognitive function. However, definitive conclusions were not possible due to the paucity of studies addressing this issue.

The authors applied cognitive-behavioral therapy (CBT) for depression using the Healthy Management of Reality treatment manual. This 16-week group treatment comprised four 4-week modules: thoughts (cognitive restructuring), activities (behavioral activation), people (interpersonal skills training), and health (addresses physical health and depression). They illustrated the use of the culture-sensitive treatment manuals by way of the member characteristics and clinical process of a Spanish-language CBT group for depression. They highlighted the challenges and satisfactions of working with a Spanish-speaking population in the public sector, and focused on how culture and socioeconomic status influence patients, and how to adapt treatment to these factors. Last, they demonstrated how technological advances integrate with culture-sensitive, evidence-based treatments to better serve this population and reduce disparities. PMID:20549680

Cognitive and emotional behavioural changes associated with methylphenidate treatment: a review of preclinical studies.

Britton, Gabrielle B

2012-02-01

There is evidence from animal studies that repeated exposure to methylphenidate (MPH), a widely used psychostimulant for the treatment of attention deficit hyperactivity disorder (ADHD), produces behavioural, structural and neurochemical changes that persist long after drug administration has ended. However, the translational utility of much of this work is compromised by the use of drug doses and routes of administration that produce plasma and brain MPH levels that fall outside the clinical range, i.e. experimental parameters more relevant to drug abuse than ADHD. We used PubMed to identify pre-clinical studies that employed repeated MPH administration at low doses in young rodents and examined long-term effects on cognition, emotion, and brain structure and function. A review of this work suggests that repeated MPH treatment during early development can modify a number of cognitive, behavioural and brain processes, but these are reduced when low therapeutic doses are employed. Moreover, MPH sites of action extend beyond those implicated in ADHD. Studies that combined neurobiological and behavioural approaches provide important insights into the mechanisms underlying MPH-produced effects on cognitive and behavioural processes, which may be relevant to MPH therapeutic efficacy. There is an emerging consensus that pharmacological treatment of childhood psychiatric disorders produces persistent neuroadaptations, highlighting the need for studies that assess long-term effects of early developmental pharmacotherapy. In this regard, studies that mimic clinical therapy with rodents are useful experimental approaches for defining the behavioural and neural plasticity associated with stimulant therapy in paediatric populations.

This study examined (a) relationships between trauma-related cognitions and posttraumatic stress disorder (PTSD) symptoms from pretreatment through a long-term period after cognitive-behavioral therapy (CBT) for PTSD and (b) whether these relationships were impacted by treatment type. Participants were 171 women randomized into treatment for PTSD after rape. Measures of self-reported trauma-related cognitions and interviewer-assessed PTSD symptoms (i.e., Posttraumatic Maladaptive Beliefs Scale, Trauma-Related Guilt Inventory, and Clinician-Administered PTSD Scale) were obtained at pretreatment, posttreatment, and 3-month, 9-month, and 5-10 year follow-ups. Multilevel regression analyses were used to examine relationships between trauma-related cognitions and PTSD symptoms throughout the study period and whether these relationships differed as a function of treatment type (i.e., Cognitive Processing Therapy or Prolonged Exposure). Initial multilevel regression analyses that examined mean within-participant associations suggested that beliefs regarding Reliability and Trustworthiness of Others, Self-Worth and Judgment, Threat of Harm, and Guilt were related to PTSD symptoms throughout follow-up. Growth curve modeling suggested that patterns of belief change throughout follow-up were similar to those previously observed in PTSD symptoms over the same time period. Finally, multilevel mediation analyses that incorporated time further suggested that change in beliefs was related to change in symptoms throughout follow-up. With 1 minor exception, relationships between beliefs and symptoms were not moderated by treatment type. These data suggest that trauma-related cognitions are a potential mechanism for long-term maintenance of treatment gains after CBT for PTSD. Moreover, these cognitions may be a common, rather than specific, treatment maintenance mechanism. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Considerable research has described students' deep and surface approaches to learning. Other research has described individuals' self-regulated learning and need for cognition. There is a need for research examining the relationships among these constructs. This study explored relationships among approaches to learning (deep, surface), need for cognition, and three types of control of learning (adaptive, inflexible, irresolute). Theory suggested similarities among the deep approach, need for cognition, and adaptive control (aspects of self-regulated learning); and among surface, inflexible, and irresolute control (aspects of an ineffective approach to learning). One-factor and two-factor models were proposed. Participants were 226 Canadian military college students. Participants completed the following questionnaires: the Study Process Questionnaire (Biggs, 1978), the Need for Cognition Scale (Cacioppo & Petty, 1982), and the Strategic Flexibility Questionnaire (Cantwell & Moore, 1996). Confirmatory factor analysis supported the identification of the six scale factors. Second order confirmatory factor analysis indicated three factors representing constructs underlying these factors. Neither the one- nor two-factor models accounted adequately for the data. Self-regulated learning was defined by measures of the deep approach to learning, need for cognition, and adaptive control of learning. The second factor divided into one factor consisting of irresolute control, the surface approach, and negative need for cognition; and another consisting of inflexible and negative adaptive control. Substantial relationships among scales support the need for further theory development.

Cognitive Hypnotherapy for Accessing and Healing Emotional Injuries for Anxiety Disorders.

2016-07-01

Although anxiety disorders on the surface may appear simple, they often represent complex problems that are compounded by underlying factors. For these reasons, treatment of anxiety disorders should be individualized. This article describes cognitive hypnotherapy, an individual comprehensive treatment protocol that integrates cognitive, behavioral, mindfulness, psychodynamic, and hypnotic strategies in the management of anxiety disorders. The treatment approach is based on the self-wounds model of anxiety disorders, which provides the rationale for integrating diverse strategies in the psychotherapy for anxiety disorders. Due to its evidence-based and integrated nature, the psychotherapy described here provides accuracy, efficacy, and sophistication in the formulation and treatment of anxiety disorders. This model can be easily adapted to the understanding and treatment of other emotional disorders.

Current approaches to treatments for schizophrenia spectrum disorders, part II: psychosocial interventions and patient-focused perspectives in psychiatric care

Full Text Available Wai Tong Chien, Sau Fong Leung, Frederick KK Yeung, Wai Kit Wong School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong Abstract: Schizophrenia is a disabling psychiatric illness associated with disruptions in cognition, emotion, and psychosocial and occupational functioning. Increasing evidence shows that psychosocial interventions for people with schizophrenia, as an adjunct to medications or usual psychiatric care, can reduce psychotic symptoms and relapse and improve patients' long-term outcomes such as recovery, remission, and illness progression. This critical review of the literature was conducted to identify the common approaches to psychosocial interventions for people with schizophrenia. Treatment planning and outcomes were also explored and discussed to better understand the effects of these interventions in terms of person-focused perspectives such as their perceived quality of life and satisfaction and their acceptability and adherence to treatments or services received. We searched major healthcare databases such as EMBASE, MEDLINE, and PsycLIT and identified relevant literature in English from these databases. Their reference lists were screened, and studies were selected if they met the criteria of using a randomized controlled trial or systematic review design, giving a clear description of the interventions used, and having a study sample of people primarily diagnosed with schizophrenia. Five main approaches to psychosocial intervention had been used for the treatment of schizophrenia: cognitive therapy (cognitive behavioral and cognitive remediation therapy, psychoeducation, family intervention, social skills training, and assertive community treatment. Most of these five approaches applied to people with schizophrenia have demonstrated satisfactory levels of short- to medium-term clinical efficacy in terms of symptom control or reduction, level of

A statistical approach for segregating cognitive task stages from multivariate fMRI BOLD time series

Full Text Available Multivariate pattern analysis can reveal new information from neuroimaging data to illuminate human cognition and its disturbances. Here, we develop a methodological approach, based on multivariate statistical/machine learning and time series analysis, to discern cognitive processing stages from fMRI blood oxygenation level dependent (BOLD time series. We apply this method to data recorded from a group of healthy adults whilst performing a virtual reality version of the delayed win-shift radial arm maze task. This task has been frequently used to study working memory and decision making in rodents. Using linear classifiers and multivariate test statistics in conjunction with time series bootstraps, we show that different cognitive stages of the task, as defined by the experimenter, namely, the encoding/retrieval, choice, reward and delay stages, can be statistically discriminated from the BOLD time series in brain areas relevant for decision making and working memory. Discrimination of these task stages was significantly reduced during poor behavioral performance in dorsolateral prefrontal cortex (DLPFC, but not in the primary visual cortex (V1. Experimenter-defined dissection of time series into class labels based on task structure was confirmed by an unsupervised, bottom-up approach based on Hidden Markov Models. Furthermore, we show that different groupings of recorded time points into cognitive event classes can be used to test hypotheses about the specific cognitive role of a given brain region during task execution. We found that whilst the DLPFC strongly differentiated between task stages associated with different memory loads, but not between different visual-spatial aspects, the reverse was true for V1. Our methodology illustrates how different aspects of cognitive information processing during one and the same task can be separated and attributed to specific brain regions based on information contained in multivariate patterns of voxel

Health care organizations employ simulation-based team training (SBTT) to improve skill, communication and coordination in a broad range of critical care contexts. Quantitative approaches, such as team performance measurements, are predominantly used to measure SBTTs effectiveness. However, a practical evaluation method that examines how this approach supports cognition and teamwork is missing. We have applied Distributed Cognition for Teamwork (DiCoT), a method for analysing cognition and collaboration aspects of work settings, with the purpose of assessing the methodology's usefulness for evaluating SBTTs. In a case study, we observed and analysed four Emergo Train System® simulation exercises where medical professionals trained emergency response routines. The study suggests that DiCoT is an applicable and learnable tool for determining key distributed cognition attributes of SBTTs that are of importance for the simulation validity of training environments. Moreover, we discuss and exemplify how DiCoT supports design of SBTTs with a focus on transfer and validity characteristics. Practitioner Summary: In this study, we have evaluated a method to assess simulation-based team training environments from a cognitive ergonomics perspective. Using a case study, we analysed Distributed Cognition for Teamwork (DiCoT) by applying it to the Emergo Train System®. We conclude that DiCoT is useful for SBTT evaluation and simulator (re)design.

Demographic changes are increasing the pressure to improve therapeutic strategies against cognitive decline in Alzheimer disease (AD) and mild cognitive impairment (MCI). Besides drug treatment, physical activity seems to be a promising intervention target as epidemiological and clinical studies suggest beneficial effects of exercise training on cognition. Using comparable inclusion and exclusion criteria, we analyzed the efficacy of drug therapy (cholinesterase inhibitors, memantine, and Ginkgo biloba) and exercise interventions for improving cognition in AD and MCI populations. We searched The Cochrane Library, EBSCO, OVID, Web of Science, and U.S Food and Drug Administration data from inception through October 30, 2013. Randomized controlled trials in which at least one treatment arm consisted of an exercise or a pharmacological intervention for AD or MCI patients, and which had either a non-exposed control condition or a control condition that received another intervention. Treatment discontinuation rates and Standardized Mean Change score using Raw score standardization (SMCR) of cognitive performance were calculated. Discontinuation rates varied substantially and ranged between 0% and 49% with a median of 18%. Significantly increased discontinuation rates were found for galantamine and rivastigmine as compared to placebo in AD studies. Drug treatments resulted in a small pooled effect on cognition (SMCR: 0.23, 95% CI: 0.20 to 0.25) in AD studies (N = 45, 18,434 patients) and no effect in any of the MCI studies (N = 5, 3,693 patients; SMCR: 0.03, 95% CI: 0.00 to 0.005). Exercise interventions had a moderate to strong pooled effect size (SMCR: 0.83, 95% CI: 0.59 to 1.07) in AD studies (N = 4, 119 patients), and a small effect size (SMCR: 0.20, 95% CI: 0.11 to 0.28) in MCI (N = 6, 443 patients). Drug treatments have a small but significant impact on cognitive functioning in AD and exercise has the potential to improve cognition in AD and MCI. Head

Cognitive-behavioral play therapy.

Knell, S M

1998-03-01

Discusses cognitive-behavioral play therapy (CBPT), a developmentally sensitive treatment for young children that relies on flexibility, decreased expectation for verbalizations by the child, and increased reliance on experiential approaches. The development of CBPT for preschool-age children provides a relatively unique adaptation of cognitive therapy as it was originally developed for adults. CBPT typically contains a modeling component through which adaptive coping skills are demonstrated. Through the use of play, cognitive change is communicated indirectly, and more adaptive behaviors can be introduced to the child. Modeling is tailored for use with many specific cognitive and behavioral interventions. Generalization and response prevention are important features of CBPT. With minor modifications, many of the principles of cognitive therapy, as delineated for use with adults, are applicable to young children. Case examples are presented to highlight the application of CBPT. Although CBPT has a sound therapeutic base and utilizes proven techniques, more rigorous empirical scrutiny is needed.

Placebo effect refers to beneficial changes induced by the use of inert treatment, such as placebo-induced relief of physical pain and attenuation of negative affect. To date, we know little about whether placebo treatment could facilitate social functioning, a crucial aspect for well-being of a social species. In the present study, we develop and validate a paradigm to induce placebo effects on social trust and approach behavior (social placebo effect), and show robust evidence that placebo treatment promotes trust in others and increases preference for a closer interpersonal distance. We further examine placebo effects in real-life social interaction and show that placebo treatment makes single, but not pair-bonded, males keep closer to an attractive first-met female and perceive less social anxiety in the female. Finally, we show evidence that the effects of placebo treatment on social trust and approach behavior can be as strong as the effect of intranasal administration of oxytocin, a neuropeptide known for its function in facilitating social cognition and behavior. The finding of the social placebo effect extends our understanding of placebo effects on improvement of physical, mental, and social well-being and suggests clinical potentials in the treatment of social dysfunction.

There is growing evidence confirming increased inflammation in a subset of adults with depression. The impact of this relationship has mostly been considered in biologically based interventions; however, it also has potential implications for psychological therapies. Cognitive behaviour therapy is the most commonly used psychological intervention for the treatment of depression with theories around its efficacy primarily based on psychological mechanisms. However, cognitive behaviour therapy may have an effect on, and its efficacy influenced by, physiological processes associated with depression. Accordingly, the purpose of this systematic review was to examine the relationship between cognitive behaviour therapy and inflammation. Studies examining the anti-inflammatory effects of cognitive behaviour therapy in people with depression and other medical conditions (e.g. cancer, diabetes and heart disease) were examined. In addition, the relationship between change in inflammatory markers and change in depressive symptoms following cognitive behaviour therapy, and the influence of pre-treatment inflammation on cognitive behaviour therapy treatment response were reviewed. A total of 23 studies investigating the anti-inflammatory effects of cognitive behaviour therapy were identified. In 14 of these studies, at least one reduction in an inflammatory marker was reported, increases were identified in three studies and no change was found in six studies. Three studies examined the relationship between change in inflammation and change in depressive symptoms following cognitive behaviour therapy. In two of these studies, change in depressive symptoms was associated with a change in at least one inflammatory marker. Finally, three studies examined the influence of pre-treatment inflammation on treatment outcome from cognitive behaviour therapy, and all indicated a poorer treatment response in people with higher premorbid inflammation. Preliminary evidence suggests

If treatments for cognitive impairment are to be utilized successfully, clinicians must be able to determine whether they are effective and which patients should receive them. In order to develop consensus on these issues, the International Society for CNS Clinical Trials and Methodology (ISCTM) held a meeting of experts on March 20, 2014, in Washington, DC. Consensus was reached on several important issues. Cognitive impairment and functional disability were viewed as equally important treatment targets. The group supported the notion that sufficient data are not available to exclude patients from available treatments on the basis of age, severity of cognitive impairment, severity of positive symptoms, or the potential to benefit functionally from treatment. The group reached consensus that cognitive remediation is likely to provide substantial benefits in combination with procognitive medications, although a substantial minority believed that medications can be administered without nonpharmacological therapy. There was little consensus on the best methods for assessing cognitive change in clinical practice. Some participants supported the view that performance-based measures are essential for measurement of cognitive change; others pointed to their cost and time requirements as evidence of impracticality. Interview-based measures of cognitive and functional change were viewed as more practical, but lacking validity without informant involvement or frequent contact from clinicians. The lack of consensus on assessment methods was viewed as attributable to differences in experience and education among key stakeholders and significant gaps in available empirical data. Research on the reliability, validity, sensitivity, and practicality of competing methods will facilitate consensus. © The Author 2015.

Interdisciplinary cognitive rehabilitation is emerging as the expected standard of care for individuals with mild to moderate degrees of cognitive impairment for a variety of etiologies. There is a growing body of evidence in cognitive rehabilitation literature supporting the involvement of multiple disciplines, with the use of cognitive support technologies (CSTs), in delivering cognitive therapy to individuals who require cognitive rehabilitative therapies. This article provides an overview of the guiding theories related to traditional approaches of cognitive rehabilitation and the positive impact of current theoretical models of an interdisciplinary approach in clinical service delivery of this rehabilitation. A theoretical model of the Integrative Cognitive Rehabilitation Program (ICRP) will be described in detail along with the practical substrates of delivering specific interventions to individuals and caregivers who are living with mild to moderate cognitive impairment. The ultimate goal of this article is to provide a clinically useful resource for direct service providers. It will serve to further clinical knowledge and understanding of the evolution from traditional silo based treatment paradigms to the current implementation of multiple perspectives and disciplines in the pursuit of patient centered care. The article will discuss the theories that contributed to the development of the interdisciplinary team and the ICRP model, implemented with individuals with mild to moderate cognitive deficits, regardless of etiology. The development and implementation of specific assessment and intervention strategies in this cognitive rehabilitation program will also be discussed. The assessment and intervention strategies utilized as part of ICRP are applicable to multiple clinical settings in which individuals with cognitive impairment are served. This article has specific implications for rehabilitation which include: (a) An Interdisciplinary Approach is an

Cognitive and Self-regulatory Mechanisms of Obesity Study (COSMOS): Study protocol for a randomized controlled weight loss trial examining change in biomarkers, cognition, and self-regulation across two behavioral treatments.

Obesity is a global epidemic, yet successful interventions are rare. Up to 60% of people fail to achieve clinically meaningful, short-term weight loss (5-10% of start weight), whereas up to 72% are unsuccessful at achieving long-term weight loss (5-10% loss for ≥5years). Understanding how biological, cognitive, and self-regulatory factors work together to promote or to impede weight loss is clearly needed to optimize obesity treatment. This paper describes the methodology of the Cognitive and Self-regulatory Mechanisms of Obesity Study (the COSMOS trial). COSMOS is the first randomized controlled trial to investigate how changes in multiple biopsychosocial and cognitive factors relate to weight loss and one another across two weight loss treatments. The specific aims are to: 1) Confirm that baseline obesity-related physiological dysregulation is linked to cognitive deficits and poorer self-regulation, 2) Evaluate pre- to post-treatment change across time to assess individual differences in biomarkers, cognition, and self-regulation, and 3) Evaluate whether the acceptance-based treatment (ABT) group has greater improvements in outcomes (e.g., greater weight loss and less weight regain, improvements in biomarkers, cognition, and self-regulation), than the standard behavioral treatment group (SBT) from pre- to post-treatment and 1-year follow-up. The results of COSMOS will provide critical information about how dysregulation in biomarkers, cognition, and/or self-regulation is related to weight loss and whether weight loss treatments are differentially associated with these factors. This information will be used to identify promising treatment targets that are informed by biological, cognitive, and self-regulatory factors in order to advance obesity treatment.

2010-11-01

Full Text Available Abstract Background Cognitive behavioral therapy (CBT represents a learning process leading to symptom relief and resulting in long-term changes in behavior. CBT for panic disorder is based on exposure and exposure-based processes can be studied in the laboratory as extinction of experimentally acquired fear responses. We have recently demonstrated that the ability to extinguish learned fear responses is associated with a functional genetic polymorphism (COMTval158met in the COMT gene and this study was aimed at transferring the experimental results on the COMTval158met polymorphism on extinction into a clinical setting. Methods We tested a possible effect of the COMTval158met polymorphism on the efficacy of CBT, in particular exposure-based treatment modules, in a sample of 69 panic disorder patients. Results We present evidence that panic patients with the COMTval158met met/met genotype may profit less from (exposure-based CBT treatment methods as compared to patients carrying at least one val-allele. No association was found with the 5-HTTLPR/rs25531 genotypes which is presented as additional material. Conclusions We were thus able to transfer findings on the effect of the COMTval158met polymorphism from an experimental extinction study obtained using healthy subjects to a clinical setting. Furthermore patients carrying a COMT val-allele tend to report more anxiety and more depression symptoms as compared to those with the met/met genotype. Limitations of the study as well as possible clinical implications are discussed.

Sevginar Vatan

Full Text Available The psychological functioning of an individual includes well-being, cognitions, emotions and behaviors as a whole. In the current models of psychopathologies, as similar to well-being, reciprocal interaction between emotions, behaviors and cognitions is emphasized. Notwithstanding that the effects of these three components on cognitive behavior therapies can be mentioned too, it can be claimed that emotions were remained in the background by the behaviors and cognitions until the third wave of cognitive behavior therapies. Emotions have became prominent with the third wave approaches in the field of cognitive behavior therapy. In this review article, similarities and differences of third wave of cognitive behavior therapy with other waves, the constructs of emotion and emotion regulation in the third wave and the impacts of these on treatment were included. Additionally, throughout this perspective, treatment processes focusing on emotion regulation skills were discussed.

Piracetam is a cognitive-enhancing agent that is used for the treatment of cognitive impairments of various etiologies. Little is known about its side effect profile, especially in those with psychiatric illness. We herewith present two cases with cognitive impairment who had contrasting responses to piracetam. One of them with organic amnestic syndrome had significant improvement, whereas the other who had an organic personality change as well as a family history of mental illness had significant worsening of behavioral problems after piracetam was introduced. This report highlights the need for caution in the use of piracetam, especially in those with past or family history of psychiatric illness. Copyright © 2013 Elsevier Inc. All rights reserved.

Reliable assessment of cognitive functions is a challenging task in amyotrophic lateral sclerosis (ALS) patients unable to speak and write. We therefore present an eye-tracking based neuropsychological screening tool based on the Edinburgh Cognitive and Behavioural ALS Screen (ECAS), a standard screening tool for cognitive deficits in ALS. In total, 46 ALS patients and 50 healthy controls matched for age, gender and education were tested with an oculomotor based and a standard paper-and-pencil version of the ECAS. Significant correlation between both versions was observed for ALS patients and healthy controls in the ECAS total score and in all of its ALS-specific domains (all r > 0.3; all p ALS patients and healthy controls in the ECAS total score (p ALS patients who are unable to speak or write.

Neuropsychologists as primary care providers of cognitive health: A novel comprehensive cognitive wellness service delivery model.

2018-01-01

By virtue of their extensive knowledge base and specialized training in brain-behavior relationships, neuropsychologists are especially poised to execute a unique broad-based approach to overall cognitive wellness and should be viewed as primary care providers of cognitive health. This article will describe a novel comprehensive cognitive wellness service delivery model including cognitive health, anti-aging, lifelong wellness, and longevity-oriented practices. These practice areas include brain-based cognitive wellness, emotional and spiritually centric exploration, and related multimodality health interventions. As experts in mind-body connections, neuropsychologists can provide a variety of evidence-based treatment options, empowering patients with a sense of value and purpose. Multiple areas of clinical therapy skill-based learning, tailor-made to fit individual needs, will be discussed including: brain stimulating activities, restorative techniques, automatic negative thoughts and maladaptive thinking reduction, inflammation and pain management techniques, nutrition and culinary focused cognitive wellness, spirituality based practices and mindfulness, movement and exercise, alternative/complimentary therapies, relationship restoration/social engagement, and trauma healing/meaning. Cognitive health rests upon the foundation of counteracting mind-body connection disruptions from multiple etiologies including inflammation, chronic stress, metabolic issues, cardiac conditions, autoimmune disease, neurological disorders, infectious diseases, and allergy spectrum disorders. Superimposed on these issues are lifestyle patterns and negative health behaviors that develop as ill-fated compensatory mechanisms used to cope with life stressors and aging. The brain and body are electrical systems that can "short circuit." The therapy practices inherent in the proposed cognitive wellness service delivery model can provide preventative insulation and circuit breaking against

This review article is an overview of the effectiveness of internet-based cognitive behavioral therapy (ICBT) in the treatment of psychiatric disorders. ICBT's effectiveness has been investigated in treating and managing conditions like depression, generalized anxiety disorder (GAD), panic disorder, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD), adjustment disorder, bipolar disorder, chronic pain, and phobias. ICBT's role in the treatment of medical conditions such as diabetes mellitus with comorbid psychiatric illnesses was also explored. Furthermore, this study elaborates on its cost-effectiveness and its impact in rural areas. We conducted a thorough literature search using PubMed and Google Scholar with no restrictions on the date. ICBT's role in treating and controlling psychiatric illnesses has been established in the literature. From the data compiled, we conclude that ICBT is useful in treating mental health and medical illnesses with psychiatric comorbidities. It has also been found to be cost-effective for patients and society. ICBT is a potential tool emerging with modern day technological advancements and is useful in rural and urban settings, across various languages and cultures, and on a global scale. Larger randomized control trials on its use in clinical practice and in reaching rural populations are bound to shed more light on the effectiveness of this tool along with spreading awareness among physician and patient communities.

Currently, no evidence-based treatment is available for mood problems after stroke. We present a new psychological intervention designed to reduce depressive complaints after stroke. This intervention was based on cognitive behavioural therapy principles and was shown feasible in a pilot study. In order to meet the specific needs of stroke patients (concerning both sensori-motor, cognitive, and behavioural problems), we incorporated motivational interviewing, grief resolution, and psycho-education. We emphasised for each session to take into account the cognitive deficits of the patients (i.e. be concrete, accessible, structured, specific, and repeat information). Moreover, we augmented the psychologist-administered therapy with the contribution of an occupational or movement therapist aimed at facilitating patients' goal-setting and attainment. The intervention consisted of 12 one-hour sessions with a psychologist and three or four one-hour sessions with an occupational or movement therapist. Currently, the effectiveness of the intervention is evaluated in a randomised controlled trial. The proposed psychological treatment protocol is innovative, as it applies cognitive behavioural therapy in a stroke-specific manner; moreover, it supports goal attainment by incorporating occupational or movement therapy sessions. © The Author(s) 2014.

Vega, Jennifer N.; Newhouse, Paul A.

2014-01-01

Mild cognitive impairment (MCI) is widely regarded as the intermediate stage of cognitive impairment between the changes seen in normal cognitive aging and those associated with dementia. Elderly patients with MCI constitute a high-risk population for developing dementia, in particular Alzheimer’s disease (AD). Although the core clinical criteria for MCI have remained largely unchanged, the operational definition of MCI has undergone several revisions over the course of the last decade and remains an evolving diagnosis. Prognostic implications of this diagnosis are becoming clearer with regard to the risk of progressive cognitive deterioration. Although patients with MCI may represent an optimal target population for pharmacological and non-pharmacological interventions, results from clinical trials have been mixed and a definitive effective treatment remains elusive. This article provides a brief overview of the evolution of the concept of MCI and reviews current diagnostic criteria, the longitudinal course of the disorder, and current and emerging treatments for MCI.

research objectives of this study. Two independent coders then coded the video/audio recordings and the additional design data using Halfin's (1973) 17 mental processes for technological problem-solving. The results of this study indicated that the participants employed a wide array of mental processes when solving engineering design challenges. However, the findings provide a general analysis of the number of times participants employed each mental process, as well as the amount of time consumed employing the various mental processes through the different stages of the engineering design process. The results indicated many similarities between the students solving the problem, which may highlight voids in current technology and engineering education curricula. Additionally, the findings showed differences between the processes employed by participants that created the most successful solutions and the participants who developed the least effective solutions. Upon comparing and contrasting these processes, recommendations for instructional strategies to enhance a student's capability for solving engineering design problems were developed. The results also indicated that students, when left without teacher intervention, use a simplified and more natural process to solve design challenges than the 12-step engineering design process reported in much of the literature. Lastly, these data indicated that students followed two different approaches to solving the design problem. Some students employed a sequential and logical approach, while others employed a nebulous, solution centered trial-and-error approach to solving the problem. In this study the participants who were more sequential had better performing solutions. Examining these two approaches and the student cognition data enabled the researcher to generate a conceptual engineering design model for the improved teaching and development of engineering design problem solving.

Cognitive-behavioral therapy for persistent pain: does adherence after treatment affect outcome?

Curran, Charlotte; Williams, Amanda C de C; Potts, Henry W W

2009-02-01

It is a tenet of cognitive behavioral treatment of persistent pain problems that ex-patients should adhere to treatment methods over the longer term, in order to maintain and to extend treatment gains. However, no research has quantified the causal influence of adherence on short-term outcome in this field. The aims of this study are to assess determinants of adherence to treatment recommendations in several domains, and to examine the extent to which cognitive and behavioral adherence predicts better outcome of cognitive behavioral treatment for persistent pain. Longitudinal data from a sample of 2345 persistent pain patients who attended a multicomponent treatment programme were subjected to structural equation modeling. Adherence emerged as a mediating factor linking post-treatment and follow-up treatment outcome, but contributed only 3% unique variance to follow-up outcomes. Combined end-of-treatment outcomes and adherence factors accounted for 72% of the variance in outcome at one-month follow-up. Notwithstanding shortcomings in the measurement of adherence, these findings question the emphasis normally given to adherence in the maintenance of behavioral and cognitive change, and clinical implications are discussed.

Cognitive schema and naturalistic decision making in evidence-based practices.

Science.gov (United States)

Falzer, Paul R

2004-04-01

A recent article in this journal proposed a naturalistic approach to decision making that overcomes problems intrinsic to classical decision theory. The approach emphasizes cognitive and multi-level processes, the development of expert reasoning, and the role of decision support in individual and organizational decision making. The current paper builds on this effort by suggesting a naturalistic, multi-level, theory that can facilitate the dissemination of evidence-based practices (EBPs). The paper presents "Image Theory," a theory that has been extensively investigated in other disciplines, but has yet to be utilized in medical decision research. It is suggested that its rich, empirically tested, distinctions among kinds of cognitive and organizational processes and types of decisions and tasks make Image Theory especially valuable in describing impediments to implementing EBPs. The paper discusses how naturalistic theory can assist clinicians, administrators, researchers, and policy makers in achieving a balance between evidence-based medicine and patient-centered practice.

Man, David W K

2018-05-08

Non-pharmacological means are being developed to enhance cognitive abilities in drug abusers. This study evaluated virtual reality (VR) as an intervention tool for enhancing cognitive and vocational outcomes in 90 young ketamine users (KU) randomly assigned to a treatment group (virtual reality group, VRG; tutor-administered group, TAG) or wait-listed control group (CG). Two training programmes with similar content but different delivery modes (VR-based and manual-based) were applied using a virtual boutique as a training scenario. Outcome assessments comprised the Digit Vigilance Test, Rivermead Behavioural Memory Test, Wisconsin Cart Sorting Test, work-site test and self-efficacy pre- and post-test and during 3- and 6-month follow-ups. The VRG exhibited significant improvements in attention and improvements in memory that were maintained after 3 months. Both the VRG and TAG exhibited significantly improved vocational skills after training which were maintained during follow-up, and improved self-efficacy. VR-based cognitive training might target cognitive problems in KU.

Full Text Available Schizophrenic patients have serious impairments in social cognition, which often persists after significant reduction in clinical symptoms. Community-based psychosocial treatments aim to recover social functioning for mentally ill individuals. Our aim was to examine prospective changes in social cognition and functional outcomes in two groups of schizophrenic patients involved in two forms of community-based psychosocial treatments namely case management (CM and community-based club (CC compared to a matched, treatment as usual (TAU group of patients. We hypothesized that CC and CM groups would exhibit better functional and social cognitive outcomes after a 6-month long psychosocial treatment period. Seventy-five patients participated either in CC, CM or TAU. Both CC and CM took part in community-based psychosocial treatment programs including trainings, such as communication and assertiveness trainings. In addition, CC provided group therapeutic treatments and a continuously available day care where patients had the possibility to participate in various social interactions. All participants were in remission, and on maintenance antipsychotic treatment. Participants were assessed on all study variables at two time points: baseline and after 6 months with a battery of questionnaires that examined affective face perception, affective prosody perception, pragmatic language comprehension and ToM. Our results showed that functional outcomes improved significantly in the CC as well as in the CM groups, in contrast to the TAU group. While analyzing summary scores of social cognition, it was found that only the CC group increased its performance in social cognition. In addition, a significant between-group difference in social cognitive function was found after 6 months between the three groups, with the CC group performing best. When investigating associations between changes in social cognition and changes in functional outcomes during a 6-month long

Full Text Available Abstract Due to the limited supply of mental health services for Afro-Colombian victims of violence, a Common Elements Treatment Approach (CETA intervention has been implemented in the Colombian Pacific. Given the importance of improvement in mental health interventions for this population, it is necessary to characterize this process. This article seeks to describe the implementation of CETA for Afro-Colombian victims of violence in Buenaventura and Quibdó, Colombia through case studieswith individual in-depth interviews with Lay Psychosocial Community Workers (LPCW, supervisors, and coordinators responsible for implementing CETA. From this six core categories were obtained: 1. Effect of armed conflict and poverty 2. Trauma severity 3. Perceived changes with CETA 4. Characteristics and LPCW’s performance 5. Afro-Colombian culturalapproach and 6. Strategies to promote users’ well-being.Colombian Pacific’s scenario implies several factors, such as the active armed conflict, economic crisis, and lack of mental health care resources, affecting the implementation process and the intervention effects. This implies the need to establish and strengthen partnerships between institutions in order to administer necessary mental health care for victims of violence in the Colombian Pacific.

CERN Document Server

Yu, Qiang; Hu, Jun; Tan Chen, Kay

2017-01-01

This book presents neuromorphic cognitive systems from a learning and memory-centered perspective. It illustrates how to build a system network of neurons to perform spike-based information processing, computing, and high-level cognitive tasks. It is beneficial to a wide spectrum of readers, including undergraduate and postgraduate students and researchers who are interested in neuromorphic computing and neuromorphic engineering, as well as engineers and professionals in industry who are involved in the design and applications of neuromorphic cognitive systems, neuromorphic sensors and processors, and cognitive robotics. The book formulates a systematic framework, from the basic mathematical and computational methods in spike-based neural encoding, learning in both single and multi-layered networks, to a near cognitive level composed of memory and cognition. Since the mechanisms for integrating spiking neurons integrate to formulate cognitive functions as in the brain are little understood, studies of neuromo...

2018-03-01

To systematically review the literature reporting outcomes of augmentative family-based treatment (FBT) interventions for adolescents with restrictive eating disorders (EDs). Articles were identified through a systematic search of five electronic databases (PsycINFO, MEDLINE, EMBASE, CINAHL, Cochrane Database). Thirty articles were included, reporting on FBT augmentations featuring adjunctive treatment components, modified treatment structure and/or content with adherence to FBT principles, and adaptations allowing FBT delivery in different settings. All reported significant improvements in weight and/or ED symptoms at end-of-treatment, although few compared augmentative and standard FBT interventions and good quality follow-up data was generally lacking. There is early evidence for the effectiveness of augmentative FBT-based approaches in facilitating weight and/or ED symptom improvements for adolescents with restrictive EDs. There remains a lack of robust evidence demonstrating superior effects of such approaches over standard FBT, and further controlled studies are required to expand on the current evidence.

Self-guided internet-based cognitive behavioral therapy (iCBT) has the potential to increase access and availability of evidence-based therapy and reduce the cost of depression treatment. To estimate the effect of self-guided iCBT in treating adults with depressive symptoms compared with controls and evaluate the moderating effects of treatment outcome and response. A total of 13 384 abstracts were retrieved through a systematic literature search in PubMed, Embase, PsycINFO, and Cochrane Library from database inception to January 1, 2016. Randomized clinical trials in which self-guided iCBT was compared with a control (usual care, waiting list, or attention control) in individuals with symptoms of depression. Primary authors provided individual participant data from 3876 participants from 13 of 16 eligible studies. Missing data were handled using multiple imputations. Mixed-effects models with participants nested within studies were used to examine treatment outcomes and moderators. Outcomes included the Beck Depression Inventory, Center for Epidemiological Studies-Depression Scale, and 9-item Patient Health Questionnaire scores. Scales were standardized across the pool of the included studies. Of the 3876 study participants, the mean (SD) age was 42.0 (11.7) years, 2531 (66.0%) of 3832 were female, 1368 (53.1%) of 2574 completed secondary education, and 2262 (71.9%) of 3146 were employed. Self-guided iCBT was significantly more effective than controls on depressive symptoms severity (β = -0.21; Hedges g  = 0.27) and treatment response (β = 0.53; odds ratio, 1.95; 95% CI, 1.52-2.50; number needed to treat, 8). Adherence to treatment was associated with lower depressive symptoms (β = -0.19; P = .001) and greater response to treatment (β = 0.90; P treatment outcomes. Self-guided iCBT is effective in treating depressive symptoms. The use of meta-analyses of individual participant data provides substantial evidence for clinical and

Suicidal ideation (SI) is common in chronic depression, but only limited evidence exists for the assumption that psychological treatments for depression are effective for reducing SI. In the present study, the effects of Mindfulness-based Cognitive Therapy (MBCT; group version) plus treatment-as-usual (TAU: individual treatment by either a psychiatrist or a licensed psychotherapist, including medication when indicated) and Cognitive Behavioral Analysis System of Psychotherapy (CBASP; group version) plus TAU on SI was compared to TAU alone in a prospective, bi-center, randomized controlled trial. The sample consisted of 106 outpatients with chronic depression. Multivariate regression analyses revealed different results, depending on whether SI was assessed via self-report (Beck Depression Inventory suicide item) or via clinician rating (Hamilton Depression Rating Scale suicide item). Whereas significant reduction of SI emerged when assessed via clinician rating in the MBCT and CBASP group, but not in the TAU group while controlling for changes in depression, there was no significant effect of treatment on SI when assessed via self-report. SI was measured with only two single items. Because all effects were of small to medium size and were independent of effects from other depression symptoms, the present results warrant the application of such psychotherapeutical treatment strategies like MBCT and CBASP for SI in patients with chronic depression.

We aimed to determine if resting state functional magnetic resonance imaging (fMRI) acquired at pre-treatment baseline could accurately predict breast cancer-related cognitive impairment at long-term follow-up. We evaluated 31 patients with breast cancer (age 34-65) prior to any treatment, post-chemotherapy and 1 year later. Cognitive testing scores were normalized based on data obtained from 43 healthy female controls and then used to categorize patients as impaired or not based on longitudinal changes. We measured clustering coefficient, a measure of local connectivity, by applying graph theory to baseline resting state fMRI and entered these metrics along with relevant patient-related and medical variables into random forest classification. Incidence of cognitive impairment at 1 year follow-up was 55% and was predicted by classification algorithms with up to 100% accuracy ( p breast cancer. This information could inform treatment decision making by identifying patients at highest risk for long-term cognitive impairment.

Group versus Internet-based cognitive-behavioral therapy for procrastination: Study protocol for a randomized controlled trial

Alexander Rozental

2014-04-01

Full Text Available Procrastination is defined as a voluntarily delay of an intended course of action despite expecting to be worse-off for the delay, and is considered a persistent behavior pattern that can result in major psychological suffering. About one-fifth of the adult population and half of the student population are presumed having substantial difficulties due to recurrent procrastination in their everyday lives. However, chronic and severe procrastinators seldom receive adequate care due to preconceptions and the lack of understanding regarding procrastination and the treatment interventions that are assumed beneficial. Cognitive-behavioral therapy is often deemed a treatment of choice, although the evidence supporting its use is scarce, and only one randomized controlled trial has been performed. The primary aim of the proposed study is therefore to test the efficacy of cognitive-behavioral therapy delivered as either a group intervention or via the Internet. Participants will consist of students recruited through the Student Health Centre at Karolinska Institutet. A randomized controlled trial with a sample size of 100 participants divided into blocks of thirty will be used, comparing an eight-week Internet-based cognitive-behavioral therapy intervention, and an eight-week group cognitive-behavioral therapy based intervention. It is believed that the proposed study will result in two important findings. First, different treatment interventions in cognitive-behavioral therapy are assumed to be helpful for people suffering from problems caused by procrastination. Second, both an Internet-based cognitive-behavioral therapy intervention and a group intervention are presumed suitable for administering treatment for procrastination, which is considered important as the availability of adequate care is limited, particularly among students. The proposed study will increase the knowledge regarding the efficacy of different treatments of procrastination, as well

Non-pharmachological approaches to the treatment of chronic insomnia

Full Text Available Sleep disorders have a negative impact on the quality of life and contribute to physical and mental health problems. Insomnia is a pervasive condition with various causes, manifestations, and health consequences. Even though it can be triggered by a variety of precipitating events, psychological and behavioral factors are almost always involved in perpetuating or exacerbating it over time, and lead to chronic condition. This article reviews some basic models and mechanisms of chronic insomnia as well as the rationale and objectives of cognitive-behavioral therapy (CBT in its management. CBT is a safe and effective treatment that may be used either as a monotherapy or to augment therapy with drugs. Evidence from controlled clinical trials indicates that the majority of patients (70 % to 80 % with persistent insomnia respond to this treatment, which is comparable to medication treatment. Aside from the clinically measurable changes, this therapy system enables patients to regain a feeling of control over their sleep, thereby reducing the emotional distress that sleep disorders cause. But despite the evidence for effectiveness and efficacy of these therapies and also the preference for non-pharmacological treatments expressed by many patients, psychological and behavioral approaches still remain underutilized by health care practitioners. Thus, an important challenge for the future is to disseminate these evidence-based therapies more effectively and increase their routine use in clinical practice.

2013-11-01

Full Text Available A growing literature supports cognitive therapy (CT as an efficacious treatment for youth struggling with emotional or behavioral problems. Recently, work in this area has extended the dissemination of CT to school-based settings. The current study has two aims: 1 to examine the development of therapists’ knowledge and skills in CT, an evidence-based approach to promoting student well-being, and 2 to examine patterns of narrative feedback provided to therapists participating in the program. As expected, school therapists trained in CT demonstrated significant gains in their knowledge of CT theory and in their demonstration of CT skills, with the majority of therapists surpassing the accepted threshold of competency in CT. In addition, an examination of feedback content suggested that narrative feedback provided to therapists most frequently consisted of positive feedback and instructions for future sessions. Suggestions for future research regarding dissemination of CT are discussed in light of increasing broad access to evidence based practices.

Individuals with cocaine dependence often evidence poor cognitive control. The purpose of this exploratory study was to investigate networks of functional connectivity underlying cognitive control in cocaine dependence and examine the relationship of the networks to the disorder and its treatment. Independent component analysis (ICA) was applied to fMRI data to investigate if regional activations underlying cognitive control processes operate in functional networks, and whether these networks relate to performance and treatment outcome measures in cocaine dependence. Twenty patients completed a Stroop task during fMRI prior to entering outpatient treatment and were compared to 20 control participants. ICA identified five distinct functional networks related to cognitive control interference events. Cocaine-dependent patients displayed differences in performance-related recruitment of three networks. Reduced involvement of a "top-down" fronto-cingular network contributing to conflict monitoring correlated with better treatment retention. Greater engagement of two "bottom-up" subcortical and ventral prefrontal networks related to cue-elicited motivational processing correlated with abstinence during treatment. The identification of subcortical networks linked to cocaine abstinence and cortical networks to treatment retention suggests that specific circuits may represent important, complementary targets in treatment development for cocaine dependence. 2013 APA, all rights reserved

Cognitive approach in studying of entrepreneur phenomenon

Kulakovsky T.Yu.

2017-06-01

Full Text Available The research indicates that there is no prospect of searching specific entrepreneurial traits that are necessary for conducting successful entrepreneurial activity. It is pointed on the impossibility to fully explain the negative state of domestic business exclusively by the influence of environmental factors. The paper points on the necessity of concentrating the scientific search on the cognitive features of personality, as factors that contribute to success of entrepreneurial activities. It is revealed that the decision-making process directed on problem-solving in entrepreneurial activity, from an entrepreneurial idea to obtaining an appropriate result, cannot be algorithmized. The author points out on the insufficiency of attempts to model cognitive processes of entrepreneurs, in which their cognitive activity is regarded as an information processing system that resembles a computer. The results obtained in the framework of the cognitive approach in studying the phenomenon of the entrepreneur are analyzed. Particular emphasis is placed on the features of heuristics and cognitive biases. It is stated that the high levels of uncertainty, novelty, time deficit, information overload and emotional tension facilitate influence of cognitive biases on the cognitive processes of the entrepreneur. The role of «availability heuristic», «anchoring and adjustment heuristic», «confirmation bias», «hindsight bias» and self-efficacy in making decisions about starting an entrepreneurial activity are considered. The article points to the role of «belief in the law of small numbers» and the illusion of control in establishing optimistic bias (overly positive self-esteem, excessive optimism about future plans and events that lead to reducing the subjective perception of entrepreneurial risk.

Jansson-Fröjmark, Markus; Norell-Clarke, Annika

2018-06-07

Since the beginning of the twenty-first century, there has been an increased focus on developing and testing cognitive components and therapies for insomnia disorder. The aim of the current review was thus to describe and review the efficacy of cognitive components and therapies for insomnia. A systematic review was conducted on 32 studies (N = 1455 subjects) identified through database searches. Criteria for inclusion required that each study constituted a report of outcome from a cognitive component or therapy, that the study had a group protocol, adult participants with diagnosed insomnia or undiagnosed insomnia symptoms or reported poor sleep, and that the study was published until and including 2016 in English. Each study was systematically reviewed with a standard coding sheet. Several cognitive components, a multi-component cognitive program, and cognitive therapy were identified. It is concluded that there is support for paradoxical intention and cognitive therapy. There are also other cognitive interventions that appears promising, such as cognitive refocusing and behavioral experiments. For most interventions, the study quality was rated as low to moderate. We conclude that several cognitive treatment components and therapies can be viewed as efficacious or promising interventions for patients with insomnia disorder. Methodologically stronger studies are, however, warranted. Copyright © 2018 Elsevier Ltd. All rights reserved.

Elder abuse may become a health issue in developing countries, including Iran. The purpose of this investigation was to study the effectiveness of Family-Based Cognitive-Behavioral Social Work (FBCBSW) in reducing elder abuse. In a randomized clinical trial in Iran, 27 elders participated in intervention and control groups. The intervention groups received a five-session FBCBSW intervention and completed the Domestic-Elder-Abuse-Questionnaire (DEAQ), which evaluates elder abuse at baseline and follow-ups. Repeated measures of analysis of variance (ANOVA) and the Wilcoxon test were used to analyze the data. The repeated measures ANOVA revealed that FBCBSW was successful in reducing elder abuse. The Wilcoxon test indicated that emotional neglect, care neglect, financial neglect, curtailment of personal autonomy, psychological abuse, and financial abuse significantly decreased over time, but there was no statistically significant difference in physical abuse before and after the intervention. The findings from this study suggest that FBCBSW is a promising approach to reducing elder abuse and warrants further study with larger samples.

Behavioral treatments for children and adults who stutter: a review

Full Text Available Michael Blomgren Department of Communication Sciences and Disorders, University of Utah, Salt Lake City, UT, USA Abstract: This paper provides a brief overview of stuttering followed by a synopsis of current approaches to treat stuttering in children and adults. Treatment is discussed in terms of multifactorial, operant, speech restructuring, and anxiolytic approaches. Multifactorial and operant treatments are designed for young children who stutter. Both of these approaches involve parent training and differ primarily in their focus on reducing demands on the child (multifactorial or in their use of response contingent stimulation (operant conditioning. Speech restructuring and anxiolytic approaches are used with adults who stutter. Speech restructuring approaches focus on the mechanics of speech production, and anxiolytic treatments tend to focus on the symptoms and social and vocational challenges of stuttering. The evidence base for these different approaches is outlined. Response contingent therapy (for children and speech restructuring therapy (for adults have the most robust empirical evidence base. Multifactorial treatments for children and stuttering management approaches for adults are popular but are based on theoretical models of stuttering; the evidence base is not robust and tends to be inferred from work in areas such as cognitive behavior therapy and desensitization. Comprehensive, or holistic, approaches to treating stuttering are also discussed. Comprehensive approaches for treating stuttering in adults address both improved speech fluency and stuttering management.

Chia-Kuang Tsai

Full Text Available Dementia is the supreme worldwide burden for welfare and the health care system in the 21st century. The early identification and control of the modifiable risk factors of dementia are important. Global-cognitive health (GCH metrics, encompassing controllable cardiovascular health (CVH and non-CVH risk factors of dementia, is a newly developed approach to assess the risk of cognitive impairment. The components of ideal GCH metrics includes better education, non-obesity, normal blood pressure, no smoking, no depression, ideal physical activity, good social integration, normal glycated hemoglobin (HbA1c, and normal hearing. This study focuses on the association between ideal GCH metrics and the cognitive function in young adults by investigating the Third Health and Nutrition Examination Survey (NHANES III database, which has not been reported previously. A total of 1243 participants aged 17 to 39 years were recruited in this study. Cognitive functioning was evaluated by the simple reaction time test (SRTT, symbol-digit substitution test (SDST, and serial digit learning test (SDLT. Participants with significantly higher scores of GCH metrics had better cognitive performance (p for trend <0.01 in three cognitive tests. Moreover, better education, ideal physical activity, good social integration and normal glycated hemoglobin were the optimistic components of ideal GCH metrics associated with better cognitive performance after adjusting for covariates (p < 0.05 in three cognitive tests. These findings emphasize the importance of a preventive strategy for modifiable dementia risk factors to enhance cognitive functioning during adulthood.

Compulsive buying behavior (CBB) is receiving increasing consideration in both consumer and psychiatric-epidemiological research, yet empirical evidence on treatment interventions is scarce and mostly from small homogeneous clinical samples. To estimate the short-term effectiveness of a standardized, individual cognitive behavioral therapy intervention (CBT) in a sample of n=97 treatment-seeking patients diagnosed with CBB, and to identify the most relevant predictors of therapy outcome. The intervention consisted of 12 individual CBT weekly sessions, lasting approximately 45minutes each. Data on patients' personality traits, psychopathology, sociodemographic factors, and compulsive buying behavior were used in our analysis. The risk (cumulative incidence) of poor adherence to the CBT program was 27.8%. The presence of relapses during the CBT program was 47.4% and the dropout rate was 46.4%. Significant predictors of poor therapy adherence were being male, high levels of depression and obsessive-compulsive symptoms, low anxiety levels, high persistence, high harm avoidance and low self-transcendence. Cognitive behavioral models show promise in treating CBB, however future interventions for CBB should be designed via a multidimensional approach in which patients' sex, comorbid symptom levels and the personality-trait profiles play a central role.

A patient-centred approach to treatment with incretin-based agents in patients with type 2 diabetes.

Science.gov (United States)

Cornell, Susan A

2013-06-01

The 2012 position statement from the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) recommends a haemoglobin A1c level of <7% for most patients with type 2 diabetes (T2D). Initial therapy consists of lifestyle changes plus metformin, with an emphasis on a patient-centred approach to management. Addition of incretin-based therapy is recommended as an add-on after metformin failure, and later on in combination with basal insulin. Basal insulin is recommended from the onset in patients with A1c ≥10%. The possibility of incorporating incretin-based therapy in the patient-centred approach will be investigated both in the literature and clinical experience. Incretin-based therapy targets multiple dysfunctional organ systems in T2D and provides sustained glycaemic control, with extraglycaemic benefits and low risk of hypoglycaemia. To initiate an incretin-based therapy that best fits an individual patient's needs, the patient's A1c level, preference and comorbid conditions should be considered along with any drug safety and adherence-related issues. There is good evidence to support the patient-centred approach to T2D management. This approach allows patient treatment goals and personal preferences to be matched with the clinical profile(s) of one or more agents to formulate a treatment plan that can best achieve the goals. Incretin-based therapies are an important class of agents to consider after metformin monotherapy failure and later in combination with basal insulin. By matching patient needs with the clinical profiles of the various treatment options, pharmacists can actively engage in the practice of patient-centred care and management. © 2013 Blackwell Publishing Ltd.

Treatment for bovine Escherichia coli mastitis - an evidence-based approach.

Suojala, L; Kaartinen, L; Pyörälä, S

2013-12-01

Bovine mastitis caused by Escherichia coli can range from being a subclinical infection of the mammary gland to a severe systemic disease. Cow-dependent factors such as lactation stage and age affect the severity of coliform mastitis. Evidence for the efficacy of antimicrobial treatment for E. coli mastitis is very limited. Antimicrobial resistance is generally not a limiting factor for treatment, but it should be monitored to detect changes in resistance profiles. The only antimicrobials for which there is some scientific evidence of beneficial effects in the treatment for E. coli mastitis are fluoroquinolones and cephalosporins. Both are critically important drugs, the use of which in animals destined for food should be limited to specific indications and should be based on bacteriological diagnosis. The suggested routine protocol in dairy herds could target the primary antimicrobial treatment for mastitis, specifically infections caused by gram-positive bacteria. In E. coli mastitis with mild to moderate clinical signs, a non-antimicrobial approach (anti-inflammatory treatment, frequent milking and fluid therapy) should be the first option. In cases of severe E. coli mastitis, parenteral administration of fluoroquinolones, or third- or fourth-generation cephalosporins, is recommended due to the risk of unlimited growth of bacteria in the mammary gland and ensuing bacteremia. Evidence for the efficacy of intramammary-administered antimicrobial treatment for E. coli mastitis is so limited that it cannot be recommended. Nonsteroidal anti-inflammatory drugs have documented the efficacy in the treatment for E. coli mastitis and are recommended for supportive treatment for clinical mastitis. © 2013 John Wiley & Sons Ltd.

Pandit, Shweta

2017-01-01

This book discusses the use of the spectrum sharing techniques in cognitive radio technology, in order to address the problem of spectrum scarcity for future wireless communications. The authors describe a cognitive radio medium access control (MAC) protocol, with which throughput maximization has been achieved. The discussion also includes use of this MAC protocol for imperfect sensing scenarios and its effect on the performance of cognitive radio systems. The authors also discuss how energy efficiency has been maximized in this system, by applying a simple algorithm for optimizing the transmit power of the cognitive user. The study about the channel fading in the cognitive user and licensed user and power adaption policy in this scenario under peak transmit power and interference power constraint is also present in this book.

Trichotillomania is a psychiatric condition characterized by the chronic pulling and plucking of one's own hair. Cognitive-behavioral therapy shows promise as a treatment for trichotillomania and might be preferable to pharmacotherapy. However, there have been no randomized, controlled studies of the efficacy of group cognitive-behavioral therapy. We evaluated 44 subjects, recruited from April 2009 to May 2010, all of whom met DSM-IV criteria for a diagnosis of trichotillomania. Subjects were randomized to receive 22 sessions of either group cognitive-behavioral therapy or group supportive therapy (control). Treatment evaluation was non-blind and used self-report scales. The primary outcome measure was the improvement of hair-plucking behavior as assessed by the Massachusetts General Hospital Hairpulling Scale. Secondary measures included scores on the Beck Depression Inventory, the Beck Anxiety Inventory, and the Social Adjustment Scale-Self-Report.

Addiction, as a brain disorder, can be defined with two distinct but interacting components: drug dependency and neurocognitive deficits. Most of the therapeutic interventions in addiction medicine, including pharmacological or psychosocial therapies, that are in clinical use have been mainly focused on directly addressing addictive behaviors, especially drug use and urges to use drugs. In the field of addiction treatment, it is often presumed that drug users' neurocognitive deficits will reverse following abstinence. However, in many cases, neurocognitive deficits are not fully ameliorated following sustained abstinence, and neurocognitive function may further deteriorate in early abstinence. It can be argued that many cognitive functions, such as sustained attention and executive control, are essential for full recovery and long-term abstinence from addiction. Recent advances in cognitive neuroscience have provided scientific foundations for neurocognitive rehabilitation as a means of facilitating recovery from drug addiction. Neurocognitive rehabilitation for drug addicted individuals could be implemented as part of addiction treatment, with highly flexible delivery methods including traditional "paper and pencil" testing, or computer-based technology via laptops, web-based, or smartphones in inpatient and outpatient settings. Despite this promise, there has been limited research into the potential efficacy of neurocognitive rehabilitation as a treatment for drug addiction. Further, many questions including the optimum treatment length, session duration, and necessary treatment adherence for treatment efficacy remain to be addressed. In this chapter, we first introduce cognitive rehabilitation as one of the potential areas to bridge the gap between cognitive neuroscience and addiction medicine, followed by an overview of current challenges and future directions. © 2016 Elsevier B.V.

Price, Matthew; Anderson, Page L

2012-06-01

Outcome expectancy, the extent that clients anticipate benefiting from therapy, is theorized to be an important predictor of treatment response for cognitive-behavioral therapy. However, there is a relatively small body of empirical research on outcome expectancy and the treatment of social anxiety disorder. This literature, which has examined the association mostly in group-based interventions, has yielded mixed findings. The current study sought to further evaluate the effect of outcome expectancy as a predictor of treatment response for public-speaking fears across both individual virtual reality and group-based cognitive-behavioral therapies. The findings supported outcome expectancy as a predictor of the rate of change in public-speaking anxiety during both individual virtual reality exposure therapy and group cognitive-behavioral therapy. Furthermore, there was no evidence to suggest that the impact of outcome expectancy differed across virtual reality or group treatments. PsycINFO Database Record (c) 2012 APA, all rights reserved.

The evidence base for the treatment of morbid jealousy with integrative therapies is thin. This study explored the efficacy of cognitive analytic therapy (CAT). An adjudicated hermeneutic single-case efficacy design evaluated the cognitive analytic treatment of a patient meeting diagnostic criteria for obsessive morbid jealousy. A rich case record was developed using a matrix of nomothetic and ideographic quantitative and qualitative outcomes. This record was then debated by sceptic and affirmative research teams. Experienced psychotherapy researchers acted as judges, assessed the original case record, and heard the affirmative-versus-sceptic debate. Judges pronounced an opinion regarding the efficacy of the therapy. The efficacy of CAT was supported by all three judges. Each ruled that change had occurred due to the action of the therapy, beyond any level of reasonable doubt. This research demonstrates the potential usefulness of CAT in treating morbid jealousy and suggests that CAT is conceptually well suited. Suggestions for future clinical and research directions are provided. The relational approach of CAT makes it a suitable therapy for morbid jealousy. The narrative reformulation component of CAT appears to facilitate early change in chronic jealousy patterns. It is helpful for therapists during sessions to use CAT theory to diagrammatically spell out the patterns maintaining jealousy. © 2017 The British Psychological Society.

2015-11-01

There is a paucity of randomized clinical trials (RCTs) for adolescents with bulimia nervosa (BN). Prior studies suggest cognitive-behavioral therapy adapted for adolescents (CBT-A) and family-based treatment for adolescent bulimia nervosa (FBT-BN) could be effective for this patient population. The objective of this study was to compare the relative efficacy of these 2 specific therapies, FBT-BN and CBT-A. In addition, a smaller participant group was randomized to a nonspecific treatment (supportive psychotherapy [SPT]), whose data were to be used if there were no differences between FBT-BN and CBT-A at end of treatment. This 2-site (Chicago and Stanford) randomized controlled trial included 130 participants (aged 12-18 years) meeting DSM-IV criteria for BN or partial BN (binge eating and purging once or more per week for 6 months). Outcomes were assessed at baseline, end of treatment, and 6 and 12 months posttreatment. Treatments involved 18 outpatient sessions over 6 months. The primary outcome was defined as abstinence from binge eating and purging for 4 weeks before assessment, using the Eating Disorder Examination. Participants in FBT-BN achieved higher abstinence rates than in CBT-A at end of treatment (39% versus 20%; p = .040, number needed to treat [NNT] = 5) and at 6-month follow-up (44% versus 25%; p = .030, NNT = 5). Abstinence rates between these 2 groups did not differ statistically at 12-month follow-up (49% versus 32%; p = .130, NNT = 6). In this study, FBT-BN was more effective in promoting abstinence from binge eating and purging than CBT-A in adolescent BN at end of treatment and 6-month follow-up. By 12-month follow-up, there were no statistically significant differences between the 2 treatments. Study of Treatment for Adolescents With Bulimia Nervosa; http://clinicaltrials.gov/; NCT00879151.

Results: Disconnection, rejection, impaired autonomy self-manifestation, extreme vigilance, unrelenting standards, other-directedness, and impaired limits schema domain scores were significantly higher in coronary artery disease patients with anxiety disorder comorbidity compared to coronary artery disease patients without anxiety disorder. Conclusion: Our study has revealed significant differences in cognitive profiles of coronary artery disease patients with comorbidity of anxiety disorders. These findings show the importance of cognitive profiles which were observed in coronary artery disease patients with anxiety disorders. Schema-focused approach might be useful in the treatment of such patients. Further studies with schema-focused therapy approaches are needed to illustrate the issue. [JCBPR 2012; 1(3.000: 171-177

Gait and Cognition: A Complementary Approach to Understanding Brain Function and the Risk of Falling

Montero-Odasso, Manuel; Verghese, Joe; Beauchet, Olivier; Hausdorff, Jeffrey M.

2012-01-01

Until recently, clinicians and researchers have performed gait assessments and cognitive assessments separately when evaluating older adults. Increasing evidence from clinical practice, epidemiological studies, and clinical trials shows that gait and cognition are inter-related in older adults. Quantifiable alterations in gait among older adults are associated with falls, dementia, and disability. At the same time, emerging evidence indicates that early disturbances in cognitive processes such as attention, executive function, and working memory are associated with slower gait and gait instability during single and dual-task testing, and that these cognitive disturbances assist in the prediction of future mobility loss, falls, and progression to dementia. This paper reviews the importance of the gait-cognition inter-relationship in aging and presents evidence that gait assessments can provide a window into the understanding of cognitive function and dysfunctions, and fall risk in older people in clinical practice. To this end, the benefits of dual-task gait assessments (e.g., walking while performing an attention-demanding task) as a marker of fall risk are summarized. Further, we also present a potential complementary approach for reducing the risk of falls by improving certain aspects of cognition through both non-pharmacological and pharmacological treatments. Untangling the relationship between early gait disturbances and early cognitive changes may be helpful for identifying older adults at higher risk of experiencing mobility decline, falls and the progression to dementia.

2012-09-01

We tested the efficacy of a unified cognitive-behavioral therapy protocol for anxiety disorders. This group treatment protocol, termed false safety behavior elimination therapy (F-SET), is a cognitive-behavioral approach designed for use across various anxiety disorders such as panic disorder (PD), social anxiety disorder (SAD), and generalized anxiety disorder (GAD). F-SET simplifies, as well as broadens, key therapeutic elements of empirically validated treatments for anxiety disorders to allow for easier delivery to heterogeneous groups of patients with anxiety psychopathology. Patients with a primary anxiety disorder diagnosis (N=96) were randomly assigned to F-SET or a wait-list control. Data indicate that F-SET shows good efficacy and durability when delivered to mixed groups of patients with anxieties (i.e., PD, SAD, GAD) by relatively inexperienced clinicians. Findings are discussed in the context of balancing treatment efficacy and clinical utility. Copyright © 2012. Published by Elsevier Ltd.

Does cognitive flexibility predict treatment gains in Internet-delivered psychological treatment of social anxiety disorder, depression, or tinnitus?

Full Text Available Little is known about the individual factors that predict outcomes in Internet-administered psychological treatments. We hypothesized that greater cognitive flexibility (i.e. the ability to simultaneously consider several concepts and tasks and switch effortlessly between them in response to changes in environmental contingencies would provide a better foundation for learning and employing the cognitive restructuring techniques taught and exercised in therapy, leading to greater treatment gains. Participants in three trials featuring Internet-administered psychological treatments for depression (n = 36, social anxiety disorder (n = 115 and tinnitus (n = 53 completed the 64-card Wisconsin Card Sorting Test (WCST prior to treatment. We found no significant associations between perseverative errors on the WCST and treatment gains in any group. We also found low accuracy in the classification of treatment responders. We conclude that lower cognitive flexibility, as captured by perseverative errors on the WCST, should not impede successful outcomes in Internet-delivered psychological treatments.

Full Text Available Traumatic brain injury (TBI is one of the common causes of disability in physical, psychological and social domains of functioning leading to poor quality of life. TBI leads to impairment in sensory, motor, language and emotional processing, and also in cognitive functions such as attention, information processing, executive functions and memory. Cognitive impairment plays a central role in functional recovery in TBI. Innovative methods such as music therapy to alleviate cognitive impairments have been investigated recently. The role of music in cognitive rehabilitation is evolving, based on newer findings emerging from the fields of neuromusicology and music cognition. Research findings from these fields have contributed significantly to our understanding of music perception and cognition, and its neural underpinnings. From a neuroscientific perspective, indulging in music is considered as one of the best cognitive exercises. With ‘plasticity’ as its veritable nature, brain engages in producing music indulging an array of cognitive functions and the product, the music, in turn permits restoration and alter brain functions. With scientific findings as its basis, ‘Neurologic Music Therapy’ (NMT has been developed as a systematic treatment method to improve sensorimotor, language and cognitive domains of functioning via music. A preliminary study examining the effect of NMT in cognitive rehabilitation has reported promising results in improving executive functions along with improvement in emotional adjustment and decreasing depression and anxiety following TBI. The potential usage of music-based cognitive rehabilitation therapy in various clinical conditions including TBI is yet to be fully explored. There is a need for systematic research studies to bridge the gap between increasing theoretical understanding of usage of music in cognitive rehabilitation and application of the same in a heterogeneous condition such as TBI.

The prevalence of childhood obesity has increased rapidly during the last three decades in the Netherlands. It is assumed that mainly environmental factors have contributed to this trend. Parental overweight and low social economic status are risk factors for childhood obesity. Childhood obesity affects self-esteem and has negative consequences on cognitive and social development. Obese children tend to become obese adults, which increases the risk for developing cardiovascular complications, type 2 diabetes mellitus, and psychosocial problems. Additionally, the secretion of several gastrointestinal hormones, responsible for appetite and food intake, is impaired in obese subjects. Weight reduction through lifestyle changes in order to change health risks is, until now, suggested as the preferred treatment for childhood obesity.The objective of this study is the effect evaluation of a family-based cognitive behavioral multidisciplinary lifestyle treatment. The intervention aims to establish long-term weight reduction and stabilization, reduction of obesity-related health consequences and improvement of self-image by change of lifestyle and learning cognitive behavioral techniques. In this randomized clinical trial newly presented children with obesity (8-17 years old) are divided, by randomization, in an intervention and control group, both consisting of 40 obese children. The intervention is carried out in groups of 8-11 children, and consists of respectively 7 and 5 separate group meetings for the children and their parents and 1 joint group meeting of 2 ½ hours. Main topics are education on nutrition, self-control techniques, social skills, physical activity and improvement of self-esteem. The control group is given advice on physical activity and nutrition. For normal data comparison, data were collected of 40 normal-weight children, 8-17 years old. Because of the increasing prevalence of childhood obesity and the impact on the individual as well as on society

Recent advancement in the technology of virtual reality (VR) has allowed improved applications for cognitive rehabilitation. The aim of this review is to facilitate comparisons of therapeutic efficacy of different VR interventions. A systematic approach for the review of VR cognitive rehabilitation outcome research addressed the nature of each sample, treatment apparatus, experimental treatment protocol, control treatment protocol, statistical analysis and results. Using this approach, studies that provide valid evidence of efficacy of VR applications are summarized. Applications that have not yet undergone controlled outcome study but which have promise are introduced. Seventeen studies conducted over the past eight years are reviewed. The few randomized controlled trials that have been completed show that some applications are effective in treating cognitive deficits in people with neurological diagnoses although further study is needed. Innovations requiring further study include the use of enriched virtual environments that provide haptic sensory input in addition to visual and auditory inputs and the use of commercially available gaming systems to provide tele-rehabilitation services. Recommendations are offered to improve efficacy of rehabilitation, to improve scientific rigor of rehabilitation research and to broaden access to the evidence-based treatments that this research has identified.

The Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) is commonly used to assess baseline and post-injury cognition among athletes in North America. Despite this, several studies have questioned the reliability of ImPACT when given at intervals employed in clinical practice. Poor test-retest reliability reduces test sensitivity to cognitive decline, increasing the likelihood that concussed athletes will be returned to play prematurely. We recently showed that the reliability of ImPACT can be increased when using a new composite structure and the aggregate of two baselines to predict subsequent performance. The purpose of the present study was to confirm our previous findings and determine whether the addition of a third baseline would further increase the test-retest reliability of ImPACT. Data from 97 English speaking professional hockey players who had received at least 4 ImPACT baseline evaluations were extracted from a National Hockey League Concussion Program database. Linear regression was used to determine whether each of the first three testing sessions accounted for unique variance in the fourth testing session. Results confirmed that the aggregate baseline approach improves the psychometric properties of ImPACT, with most indices demonstrating adequate or better test-retest reliability for clinical use. The aggregate baseline approach provides a modest clinical benefit when recent baselines are available - and a more substantial benefit when compared to approaches that obtain baseline measures only once during the course of a multi-year playing career. Pending confirmation in diverse samples, neuropsychologists are encouraged to use the aggregate baseline approach to best quantify cognitive change following sports concussion.

The loss of a child during pregnancy can be a traumatic event associated with long-lasting grief and psychological distress. This study examined the efficacy of an internet-based cognitive behavioral therapy program for mothers after pregnancy loss. In a randomized controlled trial with a waiting list control group, 83 participants who had lost a child during pregnancy were randomly allocated either to 5 weeks of internet therapy or to a 5-week waiting condition. Within a manualized cognitive behavioral treatment program, participants wrote ten essays on loss-specific topics. Posttraumatic stress, grief, and general psychopathology, especially depression, were assessed pretreatment, posttreatment, and at 3-month follow-up. Intention-to-treat analyses and completer analyses were performed. Relative to controls, participants in the treatment group showed significant improvements in posttraumatic stress, grief, depression, and overall mental health, but not in anxiety or somatization. Medium to large effect sizes were observed, and the improvement was maintained at 3-month follow-up. This internet-based cognitive behavioral therapy program represents an effective treatment approach with stable effects for women after pregnancy loss. Implementation of the program can thus help to improve the health care provision for mothers in this traumatic loss situation.

Guided Parent-delivered Cognitive Behaviour Therapy (GPD-CBT) is a brief, effective treatment for childhood anxiety disorders, however not all children respond favourably. To examine predictors of response to GPD-CBT. Parents of 125 children (7-12 years) with an anxiety disorder received GPD-CBT over 2.6 or 5.3h. Recovery was measured post treatment and six months later. Younger children and those with primary Generalised Anxiety Disorder (GAD) improved more post treatment, but older children and those without primary GAD had better outcomes at six month follow up. Fewer children allocated to 2.6h had recovered post treatment compared to those allocated to the 5.2h intervention, but did not differ significantly six months later. The identification of predictors of short and longer-term treatment outcomes can guide treatment decisions following this low-intensity approach. Copyright © 2016 The Authors.

How social cognition deficits affect psychopathology: A neuroscientific approach

Directory of Open Access Journals (Sweden)

Andrić Sanja

2015-01-01

Full Text Available Humans are substantially a social species. Effective mental treatment cannot be obtained without addressing social behavior. Social cognition refers to the mental processes underlying social interactions, which allow individuals to make sense of the other peoples' behavior, to decipher emotions on their faces, and to draw conclusions about their intentions. The core domains of this multifaceted concept are theory of mind, social cue perception, attributional style and emotion perception/ processing. The amygdala, orbital frontal cortex and temporal cortex areas are typically activated during the processing of information within social-emotional context. The aforementioned brain areas are recognized as the major components of the so-called 'social brain'- specialized for the social interactions in humans. Adequate perceiving and processing of the social information is essential for an effective social functioning, which becomes obvious when it goes awry. Various psychiatric disorders are characterized by social cognitive deficits, among which schizophrenias, depression-anxiety and autism spectrum disorders were most broadly studied to date. Growing evidence suggest that these deficits underlie poor functional outcomes in patients with mental health impairments and have an important role in the initiation and maintenance of the disorders' symptoms. One of the most important goals of social neuroscience research is to provide a treatment intervention that will improve patients' social cognitive skills and the functional outcome. All together, the present review aims to provide a contemporary overview of the concept of social cognition, to outline its relation to psychopathology, and to discuss the implications for clinical practice and treatment.

Patients with chronic fatigue syndrome experience extreme fatigue, which often leads to substantial limitations of occupational, educational, social and personal activities. Currently, there is no consensus regarding the treatment. Patients try many different therapies to overcome their fatigue. Although there is no consensus, cognitive behavioural therapy is seen as one of the most effective treatments. Little is known about multidisciplinary rehabilitation treatment, a combination of cognitive behavioural therapy with principles of mindfulness, gradual increase of activities, body awareness therapy and pacing. The difference in effectiveness and cost-effectiveness between multidisciplinary rehabilitation treatment and cognitive behavioural therapy is as yet unknown. The FatiGo (Fatigue-Go) trial aims to compare the effects of both treatment approaches in outpatient rehabilitation on fatigue severity and quality of life in patients with chronic fatigue syndrome. One hundred twenty patients who meet the criteria of chronic fatigue syndrome, fulfil the inclusion criteria and sign the informed consent form will be recruited. Both treatments take 6 months to complete. The outcome will be assessed at 6 and 12 months after the start of treatment. Two weeks after the start of treatment, expectancy and credibility will be measured, and patients will be asked to write down their personal goals and score their current performance on these goals on a visual analogue scale. At 6 and 14 weeks after the start of treatment, the primary outcome and three potential mediators-self-efficacy, causal attributions and present-centred attention-awareness-will be measured. Primary outcomes are fatigue severity and quality of life. Secondary outcomes are physical activity, psychological symptoms, self-efficacy, causal attributions, impact of disease on emotional and physical functioning, present-centred attention-awareness, life satisfaction, patient personal goals, self-rated improvement

The current considerations about completed suicides and suicide attempts in different cultures call the attention of professionals to this serious public health problem. Integrative approaches have shown that the confluence of multiple biological and social factors modulate various psychopathologies and dysfunctional behaviors, such as suicidal behavior. Considering the level of intermediate analysis, personality traits and cognitive functioning are also of great importance for understanding the suicide phenomenon. About cognitive factors, we can group them into cognitive schemas of reality interpretation and underlying cognitive processes. On the other hand, different types of primary cognitive alterations are related to suicidal behavior, especially those resulting from changes in frontostriatal circuits. Among such cognitive mechanisms can be highlighted the attentional bias for environmental cues related to suicide, impulsive behavior, verbal fluency deficits, non-adaptive decision-making, and reduced planning skills. Attentional bias consists in the effect of thoughts and emotions, frequently not conscious, about the perception of environmental stimuli. Suicidal ideation and hopelessness can make the patient unable to find alternative solutions to their problems other than suicide, biasing their attention to environmental cues related to such behavior. Recent research efforts are directed to assess the possible use of attention bias as a therapeutic target in patients presenting suicide behavior. The relationship between impulsivity and suicide has been largely investigated over the last decades, and there is still controversy about the theme. Although there is strong evidence linking impulsivity to suicide attempts. Effective interventions address to reduce impulsivity in clinical populations at higher risk for suicide could help in the prevention. Deficits in problem-solving ability also seem to be distorted in patients who attempt suicide. Understanding

Full Text Available Search Engine (SE is the most preferred information retrieval tool ubiquitously used. In spite of vast scale involvement of users in SE’s, their limited capabilities to understand the user/searcher context and emotions places high cognitive, perceptual and learning load on the user to maintain the search momentum. In this regard, the present work discusses a Cognitive Agent (CA based approach to support the user in Web-based search process. The work suggests a framework called Secured Cognitive Agent based Multi-strategic Intelligent Search System (CAbMsISS to assist the user in search process. It helps to reduce the contextual and emotional mismatch between the SE’s and user. After implementation of the proposed framework, performance analysis shows that CAbMsISS framework improves Query Retrieval Time (QRT and effectiveness for retrieving relevant results as compared to Present Search Engine (PSE. Supplementary to this, it also provides search suggestions when user accesses a resource previously tagged with negative emotions. Overall, the goal of the system is to enhance the search experience for keeping the user motivated. The framework provides suggestions through the search log that tracks the queries searched, resources accessed and emotions experienced during the search. The implemented framework also considers user security. Keywords: BDI model, Cognitive Agent, Emotion, Information retrieval, Intelligent search, Search Engine

The predictors of residential cognitive (RCT) and residential interpersonal Treatment (RIPT) for social phobia were explored. (1) Sotsky et al. (1991) found differential effects of CT and IPT for depression, suggesting that the level of cognitive or social dysfunction predicted differential outcome. We examined whether an analogous effect could be demonstrated in 10 weeks of residential treatment of 80 social phobia subjects. (2) We also included expectations, age of onset, severity of illness, concurrent anxiety, mood, avoidant personality disorder, and body dysmorphic disorder as predictors in this exploratory study. Main outcome was the social phobia subscale of Social Phobia and Anxiety Inventory (SPAI SP). DSM-IV axis I and II interviews were completed. (1) Sotsky et al. (1991) findings were not reproduced. However, RIPT subjects with poor general functioning were less improved following treatment. Subjects with concurrent agoraphobia responded better with RCT than subjects without agoraphobia. (2) Age of onset and expectations were the most powerful predictors of post treatment outcome. Some patient characteristics appear to impact outcome with RIPT and RCT differentially.

Full Text Available Background/Aims: Many studies have shown that not only pharmacological treatment but also cognitive stimulation in the early stages of Alzheimer's disease (AD improves language processing and (other cognitive functions, stabilizes Activities of Daily Living (ADL and Instrumental Activities of Daily Living (IADL functions and increases the subjective quality of life (wherein a combination of pharmacological intervention and cognitive stimulation could provide greater relief of clinical symptoms than either intervention given alone. Today, it is no longer the question of whether cognitive stimulation helps but rather what kind of stimulation helps more than others. Methods: A sample of 42 subjects with mild AD (all medicated with an acetylcholinesterase inhibitor and well adjusted underwent clinical and cognitive evaluation and participated in a 6-month study with 2 experimental groups (i.e. ‘client-centered' global stimulation vs. cognitive training and a control group. Since the test performance also depends on the individual test, we used a wide variety of tests; we z-transformed the results and then calculated the mean value for the global cognitive status (using the Mini-Mental State Examination as well as for the single functional areas. Results: Between-group differences were found, they were overall in favor of the experimental groups. Different functional areas led to different treatment and test patterns. Client-centered, global, cognitive therapy stimulated many cognitive functions and thus led to a better performance in language processing and ADL/IADL. The subjective quality of life increased as well. The cognitive training (of working memory improved only the ADL/IADL performance (more, however, than client-centered, global, cognitive stimulation and stabilized the level of performance in the other three functional areas.

Stenling, Andreas; Hassmén, Peter; Holmström, Stefan

2014-01-01

People's implicit beliefs of ability have been suggested as an antecedent of achievement goal adoption, which has in turn been associated with behavioural, cognitive and affective outcomes. This study examined a conditional process model with team sport athletes' approach-avoidance achievement goals as mediators between their implicit beliefs of sport ability and sport-related cognitive anxiety. We expected gender to moderate the paths from implicit beliefs of ability to approach-avoidance goals and from approach-avoidance goals to cognitive anxiety. Team sport athletes with a mean age of 20 years (163 females and 152 males) responded to questionnaires about their implicit beliefs of sport ability, approach-avoidance goals and sport-related cognitive anxiety. Incremental beliefs, gender and the interaction between them predicted mastery-approach goals. Gender also predicted mastery-avoidance goals, with females reporting higher levels than males. Mastery-avoidance goals, gender and the interaction between them predicted cognitive anxiety, with females reporting higher levels of anxiety than males. Entity beliefs positively predicted performance-avoidance goals and the interaction between performance-approach and gender predicted anxiety. The indirect effects also showed gender differences in relation to performance-approach goals. Taken together, our results suggest that coaches trying to create a facilitating climate for their male and female athletes may be wise to consider their athletes' anxiety and achievement goal patterns as these may affect both the athletes' well-being and performance.

Electroconvulsive therapy is an effective treatment for bipolar depression, but there are concerns about whether it causes long-term neurocognitive impairment. In this multicenter randomized controlled trial, in-patients with treatment-resistant bipolar depression were randomized to either algorithm-based pharmacologic treatment or right unilateral electroconvulsive therapy. After the 6-week treatment period, all of the patients received maintenance pharmacotherapy as recommended by their clinician guided by a relevant treatment algorithm. Patients were assessed at baseline and at 6 months. Neurocognitive functions were assessed using the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery, and autobiographical memory consistency was assessed using the Autobiographical Memory Interview-Short Form. Seventy-three patients entered the trial, of whom 51 and 26 completed neurocognitive assessments at baseline and 6 months, respectively. The MATRICS Consensus Cognitive Battery composite score improved by 4.1 points in both groups (P = .042) from baseline to 6 months (from 40.8 to 44.9 and from 41.9 to 46.0 in the algorithm-based pharmacologic treatment and electroconvulsive therapy groups, respectively). The Autobiographical Memory Interview-Short Form consistency scores were reduced in both groups (72.3% vs 64.3% in the algorithm-based pharmacologic treatment and electroconvulsive therapy groups, respectively; P = .085). This study did not find that right unilateral electroconvulsive therapy caused long-term impairment in neurocognitive functions compared to algorithm-based pharmacologic treatment in bipolar depression as measured using standard neuropsychological tests, but due to the low number of patients in the study the results should be interpreted with caution.

2016-01-01

Cognitive behavioral therapy produces significant and long-lasting improvement for individuals with insomnia, but treatment resources are scarce. A "stepped care" approach has therefore been proposed, but knowledge is limited on how to best allocate patients to different treatment steps. In this study, 66 primary-care patients with insomnia attended a low-end treatment step: manual-guided cognitive behavioral therapy (CBT) for insomnia delivered by ordinary primary-care personnel. Based on clinically significant treatment effects, subjects were grouped into treatment responders or nonresponders. Baseline data were analyzed to identify predictors for treatment success. Long total sleep time at baseline assessment was the only statistically significant predictor for becoming a responder, and sleep time may thus be important to consider before enrolling patients in low-end treatments.

Cognitive dysfunction in major depressive disorder (MDD) encompasses several domains, including but not limited to executive function, verbal memory, and attention. Furthermore, cognitive dysfunction is a frequent residual manifestation in depression and may persist during the remitted phase. Cognitive deficits may also impede functional recovery, including workforce performance, in patients with MDD. The overarching aims of this opinion article are to critically evaluate the effects of available antidepressants as well as novel therapeutic targets on neurocognitive dysfunction in MDD. Conventional antidepressant drugs mitigate cognitive dysfunction in some people with MDD. However, a significant proportion of MDD patients continue to experience significant cognitive impairment. Two multicenter randomized controlled trials (RCTs) reported that vortioxetine, a multimodal antidepressant, has significant precognitive effects in MDD unrelated to mood improvement. Lisdexamfetamine dimesylate was shown to alleviate executive dysfunction in an RCT of adults after full or partial remission of MDD. Preliminary evidence also indicates that erythropoietin may alleviate cognitive dysfunction in MDD. Several other novel agents may be repurposed as cognitive enhancers for MDD treatment, including minocycline, insulin, antidiabetic agents, angiotensin-converting enzyme inhibitors, S-adenosyl methionine, acetyl-L-carnitine, alpha lipoic acid, omega-3 fatty acids, melatonin, modafinil, galantamine, scopolamine, N-acetylcysteine, curcumin, statins, and coenzyme Q10. The management of cognitive dysfunction remains an unmet need in the treatment of MDD. However, it is hoped that the development of novel therapeutic targets will contribute to 'cognitive remission', which may aid functional recovery in MDD.

Predicting Optimal Outcomes in Cognitive Therapy or Interpersonal Psychotherapy for Depressed Individuals Using the Personalized Advantage Index Approach.

Directory of Open Access Journals (Sweden)

Marcus J H Huibers

Full Text Available Although psychotherapies for depression produce equivalent outcomes, individual patients respond differently to different therapies. Predictors of outcome have been identified in the context of randomized trials, but this information has not been used to predict which treatment works best for the depressed individual. In this paper, we aim to replicate a recently developed treatment selection method, using data from an RCT comparing the effects of cognitive therapy (CT and interpersonal psychotherapy (IPT.134 depressed patients completed the pre- and post-treatment BDI-II assessment. First, we identified baseline predictors and moderators. Second, individual treatment recommendations were generated by combining the identified predictors and moderators in an algorithm that produces the Personalized Advantage Index (PAI, a measure of the predicted advantage in one therapy compared to the other, using standard regression analyses and the leave-one-out cross-validation approach.We found five predictors (gender, employment status, anxiety, personality disorder and quality of life and six moderators (somatic complaints, cognitive problems, paranoid symptoms, interpersonal self-sacrificing, attributional style and number of life events of treatment outcome. The mean average PAI value was 8.9 BDI points, and 63% of the sample was predicted to have a clinically meaningful advantage in one of the therapies. Those who were randomized to their predicted optimal treatment (either CT or IPT had an observed mean end-BDI of 11.8, while those who received their predicted non-optimal treatment had an end-BDI of 17.8 (effect size for the difference = 0.51.Depressed patients who were randomized to their predicted optimal treatment fared much better than those randomized to their predicted non-optimal treatment. The PAI provides a great opportunity for formal decision-making to improve individual patient outcomes in depression. Although the utility of the PAI

Parkinson's disease (PD) is not a single entity but rather a heterogeneous neurodegenerative disorder. The present study aims to conduct a critical systematic review of the literature to describe the main pharmacological strategies to treat cognitive dysfunction and major depressive disorder in PD patients. We performed a search of articles cited in PubMed from 2004 to 2014 using the following MeSH terms (Medical subject headings) "Parkinson disease"; "Delirium," "Dementia," "Amnestic," "Cognitive disorders," and "Parkinson disease"; "depression," "major depressive disorder," "drug therapy." We found a total of 71 studies related to pharmacological treatment in cognitive dysfunction and 279 studies for pharmacological treatment in major depressive disorder. After fulfillment of all the inclusion and exclusion criteria, 13 articles remained for cognitive dysfunction and 11 for major depressive disorder, which are presented and discussed in this study. Further research into non-motor symptoms of PD may provide insights into mechanisms of neurodegeneration, and provide better quality of life by using rational drugs.

Cognitive dysfunction associated with cancer is frequently reported and can reduce quality of life. This study evaluated a Web-based cognitive rehabilitation therapy program (eReCog) in cancer survivors compared with a waitlist control group. Adult cancer survivors with self-reported cognitive symptoms who had completed primary treatment at least 6 months prior were recruited. Participants completed telephone screening and were randomly allocated to the 4-week online intervention or waitlist. Primary outcome was perceived cognitive impairment assessed with the Functional Assessment of Cancer Therapy-Cognitive Function version 3. Secondary outcomes were additional measures of subjective cognitive functioning, objective cognitive functioning, and psychosocial variables. Seventy-six women were allocated to the intervention (n = 40) or waitlist (n = 36). A significant interaction was found on the instrumental activities of daily living measure of self-reported prospective memory whereby the intervention group reported a greater reduction in prospective memory failures than the waitlist group. Interaction trends were noted on perceived cognitive impairments (P = .089) and executive functioning (P = .074). No significant interactions were observed on other measures of objective cognitive functioning or psychosocial variables. The Web-based intervention shows promise for improving self-reported cognitive functioning in adult cancer survivors. Further research is warranted to better understand the mechanisms by which the intervention might contribute to improved self-reported cognition. Copyright © 2017 John Wiley & Sons, Ltd.

A QoS Optimization Approach in Cognitive Body Area Networks for Healthcare Applications.

2017-04-06

Wireless body area networks are increasingly featuring cognitive capabilities. This work deals with the emerging concept of cognitive body area networks. In particular, the paper addresses two important issues, namely spectrum sharing and interferences. We propose methods for channel and power allocation. The former builds upon a reinforcement learning mechanism, whereas the latter is based on convex optimization. Furthermore, we also propose a mathematical channel model for off-body communication links in line with the IEEE 802.15.6 standard. Simulation results for a nursing home scenario show that the proposed approach yields the best performance in terms of throughput and QoS for dynamic environments. For example, in a highly demanding scenario our approach can provide throughput up to 7 Mbps, while giving an average of 97.2% of time QoS satisfaction in terms of throughput. Simulation results also show that the power optimization algorithm enables reducing transmission power by approximately 4.5 dBm, thereby sensibly and significantly reducing interference.

Processing approaches to cognition: the impetus from the levels-of-processing framework.

Science.gov (United States)

Roediger, Henry L; Gallo, David A; Geraci, Lisa

2002-01-01

Processing approaches to cognition have a long history, from act psychology to the present, but perhaps their greatest boost was given by the success and dominance of the levels-of-processing framework. We review the history of processing approaches, and explore the influence of the levels-of-processing approach, the procedural approach advocated by Paul Kolers, and the transfer-appropriate processing framework. Processing approaches emphasise the procedures of mind and the idea that memory storage can be usefully conceptualised as residing in the same neural units that originally processed information at the time of encoding. Processing approaches emphasise the unity and interrelatedness of cognitive processes and maintain that they can be dissected into separate faculties only by neglecting the richness of mental life. We end by pointing to future directions for processing approaches.

Marques, Sofia; Barrocas, Daniel; Rijo, Daniel

2017-04-28

Borderline personality disorder is the most common personality disorder, with a global prevalence rate between 1.6% and 6%. It is characterized by affective disturbance and impulsivity, which lead to a high number of self-harm behaviors and great amount of health services use. International guidelines recommend psychotherapy as the primary treatment for borderline personality disorder. This paper reviews evidence about the effects and efficacy of cognitive-behavioral oriented psychological treatments for borderline personality disorder. A literature review was conducted in Medline and PubMed databases, using the following keywords: borderline personality disorder, cognitive-behavioral psychotherapy and efficacy. Sixteen randomized clinical trials were evaluate in this review, which analyzed the effects of several cognitive-behavioral oriented psychotherapeutic interventions, namely dialectical behavioral therapy, cognitive behavioral therapy, schema-focused therapy and manual-assisted cognitive therapy. All above stated treatments showed clinical beneficial effects, by reducing borderline personality disorder core pathology and associated general psychopathology, as well as by reducing the severity and frequency of self-harm behaviors, and by improving the overall social, interpersonal and global adjustment. Dialectical behavioral therapy and schema-focused therapy also caused a soaring remission rate of diagnostic borderline personality disorder criteria of 57% and 94%, respectively. Although there were differences between the psychotherapeutic interventions analysed in this review, all showed clinical benefits in the treatment of borderline personality disorder. Dialectical behavioral therapy and schema-focused therapy presented the strongest scientific data documenting their efficacy, but both interventions are integrative cognitive-behavioral therapies which deviate from the traditional cognitive-behavioral model. In summary, the available studies support

Czuchry, Michael; Dansereau, Donald F

2004-06-01

The current study examined the relationship between need for cognition (i.e., cognitive motivation or "will") and educational experience (i.e., cognitive ability or "skill") to perceived improvements during treatment of probationers receiving residential treatment within the criminal justice system. Probationers were randomly assigned to either receive motivational activities developed by the authors (the "enhanced" condition), or treatment as usual (but with access to general reading materials in lieu of the motivational activities). Need for cognition and educational experience were assessed and used as blocking variables, and ratings of progress were assessed midway and toward the end of treatment. The results indicate that both need for cognition and educational experience are important predictors of improvement during treatment, and that the motivational activities developed by the authors were particularly valuable for clients with lower levels of need for cognition.

Moving forward in treatment of posttraumatic stress disorder: innovations to exposure-based therapy.

Science.gov (United States)

Nijdam, Mirjam J; Vermetten, Eric

2018-01-01

The field of treatment of posttraumatic stress disorder (PTSD) has been a pacesetter for the changing face of psychotherapy, as is illustrated in the introduction of Virtual Reality Exposure Therapy. This paper outlines a novel approach that builds on a cognitive-motor interaction in a virtual interactive environment. It is based on the theory of memory reconsolidation and the embodiment of cognition. The framework we envision allows the patient to 'step into the past' by using forward motion as an essential ingredient to augment the impact of exposure to traumatic events. The behavioural response of approaching that is the exact opposite from the avoidance usually applied by patients and the enhancement of divergent thinking are the most prominent hypothesized mechanisms of action. This can contribute to strengthening of personal efficacy and self-reflection that is generated by high emotional engagement, as well as a sense of accomplishment and enhanced recovery as illustrated by a clinical case example. We argue that innovations with personalized virtual reality and motion need to be further investigated and implemented in current therapy settings.

Schuurs, Alana; Green, Heather J

2013-05-01

This research aimed to address the gap in evidence-based treatment available for cancer survivors who are experiencing cognitive dysfunction, through piloting a novel treatment intervention. The overall research question was whether a group cognitive rehabilitation intervention would be feasible for improving cognitive function and quality of life for people who have completed cancer treatment. Three groups of adults were recruited as follows: an intervention group of 23 cancer survivors who completed a 4-week group cognitive rehabilitation treatment, a comparison group of nine cancer survivors, and a community sample of 23 adults who had never experienced cancer. Measures of objective and subjective cognitive function, quality of life, psychosocial distress, and illness perceptions were used. The research design was non-randomised. The results indicated that the intervention was effective in improving overall cognitive function, visuospatial/constructional performance, immediate memory, and delayed memory beyond practice effects alone. It was helpful in reducing participants' perceptions of cognitive impairment and psychosocial distress, as well as promoting social functioning and understanding of cognition. The improvements were maintained at 3 months after the intervention. Participants reported a high level of satisfaction with the treatment. The results provided evidence for the feasibility of a brief group-based cognitive rehabilitation intervention to treat cognitive problems experienced by cancer survivors.

Practical, reliable "real world" measures of cognition are needed to supplement neurocognitive performance data to evaluate possible efficacy of new drugs targeting cognitive deficits associated with schizophrenia. Because interview-based measures of cognition offer one possible approach, data from the MATRICS initiative (n=176) were used to examine the psychometric properties of the Schizophrenia Cognition Rating Scale (SCoRS) and the Clinical Global Impression of Cognition in Schizophrenia (CGI-CogS). We used classical test theory methods and item response theory to derive the 10-item Cognitive Assessment Interview (CAI) from the SCoRS and CGI-CogS ("parent instruments"). Sources of information for CAI ratings included the patient and an informant. Validity analyses examined the relationship between the CAI and objective measures of cognitive functioning, intermediate measures of cognition, and functional outcome. The rater's score from the newly derived CAI (10 items) correlate highly (r=.87) with those from the combined set of the SCoRS and CGI-CogS (41 items). Both the patient (r=.82) and the informant (r=.95) data were highly correlated with the rater's score. The CAI was modestly correlated with objectively measured neurocognition (r=-.32), functional capacity (r=-.44), and functional outcome (r=-.32), which was comparable to the parent instruments. The CAI allows for expert judgment in evaluating a patient's cognitive functioning and was modestly correlated with neurocognitive functioning, functional capacity, and functional outcome. The CAI is a brief, repeatable, and potentially valuable tool for rating cognition in schizophrenia patients who are participating in clinical trials. Copyright 2010 Elsevier B.V.

A Cognitive Modeling Approach to Strategy Formation in Dynamic Decision Making

Directory of Open Access Journals (Sweden)

Sabine Prezenski

2017-08-01

Full Text Available Decision-making is a high-level cognitive process based on cognitive processes like perception, attention, and memory. Real-life situations require series of decisions to be made, with each decision depending on previous feedback from a potentially changing environment. To gain a better understanding of the underlying processes of dynamic decision-making, we applied the method of cognitive modeling on a complex rule-based category learning task. Here, participants first needed to identify the conjunction of two rules that defined a target category and later adapt to a reversal of feedback contingencies. We developed an ACT-R model for the core aspects of this dynamic decision-making task. An important aim of our model was that it provides a general account of how such tasks are solved and, with minor changes, is applicable to other stimulus materials. The model was implemented as a mixture of an exemplar-based and a rule-based approach which incorporates perceptual-motor and metacognitive aspects as well. The model solves the categorization task by first trying out one-feature strategies and then, as a result of repeated negative feedback, switching to two-feature strategies. Overall, this model solves the task in a similar way as participants do, including generally successful initial learning as well as reversal learning after the change of feedback contingencies. Moreover, the fact that not all participants were successful in the two learning phases is also reflected in the modeling data. However, we found a larger variance and a lower overall performance of the modeling data as compared to the human data which may relate to perceptual preferences or additional knowledge and rules applied by the participants. In a next step, these aspects could be implemented in the model for a better overall fit. In view of the large interindividual differences in decision performance between participants, additional information about the underlying

However, we found a larger variance and a lower overall performance of the modeling data as compared to the human data which may relate to perceptual preferences or additional knowledge and rules applied by the participants. In a next step, these aspects could be implemented in the model for a better overall fit. In view of the large interindividual differences in decision performance between participants, additional information about the underlying cognitive processes from

Forster, J.; Entrup, B.

2017-10-01

In this paper we present and evaluate a cognitive computing approach for classification of dissatisfaction and four complaint specific complaint classes in correspondence documents between insurance clients and an insurance company. A cognitive computing approach includes the combination classical natural language processing methods, machine learning algorithms and the evaluation of hypothesis. The approach combines a MaxEnt machine learning algorithm with language modelling, tf-idf and sentiment analytics to create a multi-label text classification model. The result is trained and tested with a set of 2500 original insurance communication documents written in German, which have been manually annotated by the partnering insurance company. With a F1-Score of 0.9, a reliable text classification component has been implemented and evaluated. A final outlook towards a cognitive computing insurance assistant is given in the end.

This study examined the effect of family-based treatment for bulimia nervosa (FBT-BN) and cognitive behavioral therapy for adolescents (CBT-A) on depressive symptoms and self-esteem in adolescents with BN. Data were collected from 110 adolescents, ages 12-18, who met Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, text revision criteria for BN or partial BN. Participants were randomly assigned to FBT-BN or CBT-A and completed measures of depressive symptoms and self-esteem before and after treatment and at 6- and 12-month follow-up assessments. Depressive symptoms and self-esteem significantly improved in both treatments, and neither treatment appeared superior on these clinical outcomes. Parents often worry whether FBT-BN addresses comorbid depressive symptoms and low self-esteem. Our findings address this concern, as they demonstrate that FBT-BN does not differ from CBT-A in improving depressive symptoms and self-esteem, and both treatments result in symptom improvement. These findings can help clinicians guide families to choose a treatment that addresses BN and depressive symptoms and low self-esteem.

Full Text Available Major depression is among the most common and debilitating disorders worldwide, associated with large societal and individual costs. Effective treatments exist, but accessibility is scarce. Guided Internet-Based Cognitive Behavioral Therapy (guided iCBT is a promising approach to reach more people in need of help. In the present pilot study, we investigated the outcome of a guided iCBT program for mild and moderate depression when disseminated from Sweden to Norway. The guided iCBT intervention was implemented within a university-based outpatient clinic by six student therapists under supervision. Twenty-two participants with mild and moderate depression were included in the study. Large treatment effects were found for depressive symptoms, whereas small to medium effects were observed for anxiety symptoms. More than half (55% of the participants were classified as recovered at post-treatment and more than a third (41% at follow-up. No participants had a significant deterioration from pre- to post-treatment, but two reported a significant deterioration from post-treatment to 6-month follow-up. Benchmarking the present results against those reported in the four original Swedish studies, we found that the treatment effect in the Norwegian study was slightly higher at post-treatment and slightly lower at 6-month follow-up compared to the outcome in the Swedish studies. The results should be interpreted with caution, as our sample was small and had no control group.

TOWARDS A USAGE-BASED COGNITIVE PHONOLOGY

Directory of Open Access Journals (Sweden)

Gitten Kristiansen

2006-12-01

Full Text Available The usage-based conception of language is a major tenet in Cognitive Linguistics, but cognitive phonology has not yet been developed sufficiently in this direction. Often, phonemic analysis is carried out at the high level of abstraction of `a language´, disregarding rich patterns of languageinternal variation. This paper first argues that cognitive phonology must aim at a higher degree of descriptive refinement, especially in the direction of social variation. Then it goes on to examine the implications of a usage-based and multi-faceted model for a theoretical discussion of the phoneme as a prototype category.

Eliane Correa Miotto

Full Text Available Abstract Neuropsychological rehabilitation is related to the treatment or optimization of disabilities, handicaps and cognitive deficiencies including emotional, behavioral and personality alterations, aiming at the best cognitive, neurobiological and social re-adaptation. Objective: The main aim of this paper is to review scientific studies published over the last five years on cognitive training with rehabilitation, focusing on elderly subjects with cognitive complaints and patients diagnosed with MCI. Methods: Data were generated from Medline, PsychoInfo and EMBASE including publications from 2002 to 2007 using the search terms "Mild Cognitive Impairment", "Cognitive Complaints", "Rehabilitation" and "Intervention Studies". Data collection criteria were restricted to the quality of evidence Class I. Results: Eight articles out of sixty eight previously selected were chosen because of their randomized studies, including techniques of cognitive rehabilitation in patients with cognitive complaints, MCI and neuropsychological training. Conclusions: The studies showing generalization of rehabilitation techniques to practical real life situations and use of an errorless learning approach were considered more effective in terms of maintaining treatment follow up, although further studies are recommended.

The purpose of this paper is to identify and analyze integration of Knowledge Management (KM) and Business Intelligence (BI) in order to achieve competitive edge in context of intellectual capital. Methodology includes review of literatures and analyzes the interviews data from managers in corporate sector and models established by different authors. BI technologies have strong association with process of KM for attaining competitive advantage. KM have strong influence from human and social factors and turn them to the most valuable assets with efficient system run under BI tactics and technologies. However, the term of predictive analytics is based on the field of BI. Extracting tacit knowledge is a big challenge to be used as a new source for BI to use in analyzing. The advanced approach of the analytic methods that address the diversity of data corpus - structured and unstructured - required a cognitive approach to provide estimative results and to yield actionable descriptive, predictive and prescriptive results. This is a big challenge nowadays, and this paper aims to elaborate detail in this initial work.

Subcortical ischemic vascular dementia (SIVD) caused by chronic cerebral hypoperfusion develops with progressive white matter and cognitive impairments, yet no effective therapy is available. We investigated the temporal effects of minocycline on an experimental SIVD exerted by right unilateral common carotid arteries occlusion (rUCCAO). Minocycline treated at the early stage (day 0–3), but not the late stage after rUCCAO (day 4–32) alleviated the white matter and cognitive impairments, and promoted remyelination. The actions of minocycline may not involve the inhibition of microglia activation, based on the effects after the application of a microglial activation inhibitor, macrophage migration inhibitory factor, and co-treatment with lipopolysaccharides. Furthermore, minocycline treatment at the early stage promoted the proliferation of oligodendrocyte progenitor cells (OPCs) in subventricular zone, increased OPC number and alleviated apoptosis of mature oligodendrocytes in white matter. In vitro, minocycline promoted OPC proliferation and increased the percentage of OPCs in S and G2/M phases. We provided direct evidence that early treatment is critical for minocycline to alleviate white matter and cognitive impairments after chronic cerebral hypoperfusion, which may be due to its robust effects on OPC proliferation and mature oligodendrocyte loss. So, early therapeutic time window may be crucial for its application in SIVD. PMID:26174710

2012-11-01

Excessive and potentially addictive use of the Internet among children and adolescents has emerged as a major concern in recent times. Internet addiction is often conceptualized as an impulse control disorder, with features similar to pathological gambling. However, there remains considerable debate about the core components, etiological processes, course, and maintaining factors of the disorder. This article presents a case study of a 16-year-old male with generalized pathological Internet use. Critical issues relevant to case conceptualization, assessment, and choice of therapy are examined. Although the evidence base is limited in this emerging area of clinical psychology, we provide a summary of empirically supported cognitive-behavioral techniques for Internet addiction. © 2012 Wiley Periodicals, Inc.

Emotions and Cognitions in Social Relationships: A Neurosociological Approach

Full Text Available Neurosociology is a new approach aimed at integrating social and biologicalsciences. In this paper, first we used Alan Fiske’s theory (1992 of elementary forms of social relationships as a nexus between sociological studies of groups and group-based emotions and relevant neuroscientific findings. Then, we identified types of social situations that generate basic emotions (happiness, anger, sadness, and fear within particular relationships. Individuals participate differently in these situations. Therefore, they are expected to differ in their emotions and cognitions, as well as in their underlying neural activity. Finally, we considered social affiliation and social hierarchy corresponding to communal sharing and authority ranking social relationships to demonstrate the logic of neurosociological research.

Adults with attention deficit hyperactivity disorder (ADHD) often present with a lifelong pattern of core symptoms that is associated with impairments of functioning in daily life. This has a substantial personal and economic impact. In clinical practice there is a high need for additional or alternative interventions for existing treatments, usually consisting of pharmacotherapy and/or psycho-education. Although previous studies show preliminary evidence for the effectiveness of mindfulness-based interventions in reducing ADHD symptoms and improving executive functioning, these studies have methodological limitations. This study will take account of these limitations and will examine the effectiveness of Mindfulness Based Cognitive Therapy (MBCT) in further detail. A multi-centre, parallel-group, randomised controlled trial will be conducted in N = 120 adults with ADHD. Patients will be randomised to MBCT in addition to treatment as usual (TAU) or TAU alone. Assessments will take place at baseline and at three, six and nine months after baseline. Primary outcome measure will be severity of ADHD symptoms rated by a blinded clinician. Secondary outcome measures will be self-reported ADHD symptoms, executive functioning, mindfulness skills, self-compassion, positive mental health and general functioning. In addition, a cost-effectiveness analysis will be conducted. This trial will offer valuable information about the clinical and cost-effectiveness of MBCT in addition to TAU compared to TAU alone in adults swith ADHD. ClinicalTrials.gov NCT02463396.

Full Text Available Abstract Background The prevalence of childhood obesity has increased rapidly during the last three decades in the Netherlands. It is assumed that mainly environmental factors have contributed to this trend. Parental overweight and low social economic status are risk factors for childhood obesity. Childhood obesity affects self-esteem and has negative consequences on cognitive and social development. Obese children tend to become obese adults, which increases the risk for developing cardiovascular complications, type 2 diabetes mellitus, and psychosocial problems. Additionally, the secretion of several gastrointestinal hormones, responsible for appetite and food intake, is impaired in obese subjects. Weight reduction through lifestyle changes in order to change health risks is, until now, suggested as the preferred treatment for childhood obesity. The objective of this study is the effect evaluation of a family-based cognitive behavioral multidisciplinary lifestyle treatment. The intervention aims to establish long-term weight reduction and stabilization, reduction of obesity-related health consequences and improvement of self-image by change of lifestyle and learning cognitive behavioral techniques. Study design/Methods In this randomized clinical trial newly presented children with obesity (8-17 years old are divided, by randomization, in an intervention and control group, both consisting of 40 obese children. The intervention is carried out in groups of 8-11 children, and consists of respectively 7 and 5 separate group meetings for the children and their parents and 1 joint group meeting of 2 ½ hours. Main topics are education on nutrition, self-control techniques, social skills, physical activity and improvement of self-esteem. The control group is given advice on physical activity and nutrition. For normal data comparison, data were collected of 40 normal-weight children, 8-17 years old. Discussion Because of the increasing prevalence of

Up to half of all people with HIV infection have some degree of cognitive impairment. This impairment is typically mild, but nonetheless often disabling. Although early detection of cognitive impairment offers the greatest hope of effective intervention, there are important barriers to this goal in most clinical settings. These include uncertainty about how self-reported cognitive symptoms relate to objective impairments, and the paucity of bedside measurement tools suitable for mild deficits. Clinicians need guidance in interpreting cognitive symptoms in this population, and a brief cognitive measurement tool targeted to mild impairment. We addressed these two problems together here. The objective of this study was to determine the extent to which performance on cognitive tests and self-reported cognitive symptoms form a unidimensional construct. Two hundred three HIV+ individuals completed the Montreal Cognitive Assessment, computerized cognitive tasks and a questionnaire eliciting cognitive symptoms. Rasch measurement theory was applied to determine whether patient-reported and performance items could be combined to measure cognition as a unidimensional latent construct. Performance-based items and cognitive symptoms are arranged hierarchically along the same continuum of cognitive ability, forming a measure with thresholds covering a broad spectrum of ability that has good internal reliability. The cognitive symptoms that fit the measurement model relate to important aspects of everyday life, providing evidence that the identified construct is meaningful. This finding lays the foundation for a rapid measure of cognitive ability in people with HIV infection that is feasible for routine clinical use, and shows that some cognitive symptoms are systematically related to performance in this population.

To date, the most thoroughly studied non-pharmacological approaches to managing FM are those with a focus on changing patient activities and beliefs that affect the illness. These interventions are intended to facilitate enduring improvement in pain and functional status. Lifestyle-oriented treatments include patient education, aerobic or other physical exercise, and cognitive-behavioral therapy (CBT. These interventions in FM can be delivered in medical or behavioral health care settings by trained professionals, through patient-oriented treatment manuals, or via remote-access technologies. Non-pharmacological treatments, in particular exercise and CBT, have yielded effect sizes and cost–benefit ratios comparable to medications. This paper describes lifestyle-oriented non-pharmacological treatments for FM and highlights selected literature reviews of these interventions. In addition, behavioral and practical issues are addressed that may affect these non-pharmacological treatments, including patient expectations, participant burden, and treatment availability. Recommendations are made to facilitate these interventions and potentially improve outcomes. In particular, the increasing availability of convenient home-based mobile technologies to deliver these non-pharmacological treatments is described.Keywords: cognitive-behavior therapy, exercise, education, mobile technology

Anxiety Sensitivity Physical and Cognitive Concerns in Relation to Smoking-oriented Cognition: An Examination Among Treatment-seeking Adults Who Smoke.

Elevated levels of anxiety sensitivity (AS; fear of anxiety and internal sensations) is highly common among adults who smoke, and contributes to several maladaptive smoking beliefs and behaviors. AS is comprised of 3 empirically established factors, relating to fears of social concerns, fears of physical symptoms, and fears of cognitive dyscontrol. Relatively few studies have examined how these 3 subscales pertain to smoking processes. The aim of the present investigation was to examine, among treatment-seeking adults who smoke, the interactive effects of AS-physical and cognitive concerns in relation to: perceived barriers to smoking cessation; smoking-related negative reinforcement expectancies; and smoking-related avoidance and inflexibility. Participants included 470 adults who smoke (47.8% female; mean age 37.2, SD 13.5), who were recruited to participate in a smoking-cessation treatment study. At the baseline assessment, participants completed self-report measures, including the Anxiety Sensitivity Index-3, Barriers to Cessation Scale, Smoking Consequences Questionnaire, and Avoidance and Inflexibility Scale. Results indicated that after controlling for the effects of sex, cigarette dependence, alcohol problems, tobacco-related medical illness, current axis 1 disorder, and AS-social concerns, a significant interaction emerged, such that the association between AS-cognitive concerns and the studied smoking-based cognitions were stronger among lower levels of AS-physical concerns (but not higher physical concerns). The current findings suggest that it may be beneficial to provide specialized smoking-cessation interventions for certain subgroups of adults who smoke, such as those with different AS profiles, to promote healthier beliefs about quitting.

Culture-sensitive neural substrates of human cognition: a transcultural neuroimaging approach.

Science.gov (United States)

Han, Shihui; Northoff, Georg

2008-08-01

Our brains and minds are shaped by our experiences, which mainly occur in the context of the culture in which we develop and live. Although psychologists have provided abundant evidence for diversity of human cognition and behaviour across cultures, the question of whether the neural correlates of human cognition are also culture-dependent is often not considered by neuroscientists. However, recent transcultural neuroimaging studies have demonstrated that one's cultural background can influence the neural activity that underlies both high- and low-level cognitive functions. The findings provide a novel approach by which to distinguish culture-sensitive from culture-invariant neural mechanisms of human cognition.

Wollburg, Eileen; Braukhaus, Christoph

2010-07-01

The present study is the first aimed at investigating the influence of goal definition on treatment outcome in a sample of depressed patients. Data from 657 inpatients admitted to a psychosomatic clinic in Germany being treated in a cognitive-behavioral therapy program were analyzed. Treatment goals were identified as either approach or avoidance, and the sample was classified accordingly. Patients who identified approach goals only were placed in the approach group, and those who identified at least one avoidance goal were placed in the avoidance group. Results showed that framing goals using avoidance terms was associated with less symptomatic improvement but did not affect goal attainment. Findings from this research should be utilized in practice not only for process management such as individual treatment planning but also to control outcome quality. Furthermore, goal definition should be considered as a control variable in research on depression.

Full Text Available Sarah Hamill-Skoch,1 Paul Hicks,2 Ximena Prieto-Hicks11Department of Psychiatry, 2Department of Family and Community Medicine, University of Arizona, Tuscon, AZ, USAAbstract: Major depressive disorder often begins in adolescence, is chronic and recurrent, and heightens an individual's risk for major depressive disorder in adulthood. Treatment-resistant depression is a problem for a significant minority of adolescents. Few studies have examined treatments for treatment-resistant depression among adolescents, and even fewer have examined the use of cognitive-behavioral therapy as a monotherapy or in combination with pharmacological treatments. Mental health professionals have a strong interest in understanding what treatments are appropriate for adolescents who are treatment resistant. Preliminary evidence from current published trials indicates that the use of cognitive-behavioral therapy in combination with antidepressant medication yields the best outcome for treatment-resistant depression in adolescents. Secondary analyses also suggest that the utility of cognitive behavioral therapy can be increased by ensuring adolescents receive a therapeutic dose of treatment sessions (more than nine sessions and the inclusion of two treatment components: social skills and problem solving training. Guidelines for clinicians as well as areas for future research are discussed.Keywords: cognitive behavior therapy, treatment-resistant depression, adolescent depression

2018-04-01

Many gambling-specific CBT programs seek to target either gambling-related urge or cognitions or both. However, little is known of the influence of one symptom type on another across time and whether these differ for men and women help-seeking problem gamblers. The aim of this study was threefold: to determine presence of measurement invariance for urge and cognition measures over time; to investigate the effect of baseline urge on end-of-treatment gambling-related cognitions - and the reciprocal relationship; and, identify whether these pathways differ across gender. Self-reported gambling urge (GUS), and gambling-related cognitions (GRCS) data from treatment-seeking problem gamblers prior to and post treatment (N = 223; 62% men) were analyzed with cross-lagged panel models, moderated by gender. Conceptualization of urge and cognitions were found to be temporally stable. There was no significant association between baseline GUS scores and post-treatment GRCS scores, nor the reverse relationship. Putatively, this infers that coexisting urge and gambling-related cognition components of problem gambling operate independently over time. Analyses revealed gambling urge had a significantly stronger tracking correlation across time for men than women when adjusting for cognition paths. This investigation provides early evidence for tailoring CBT in response to sub-population gambling-related characteristics, demonstrated across men and women. Copyright © 2018 Elsevier B.V.

Full Text Available Abstract Background Patients with chronic fatigue syndrome experience extreme fatigue, which often leads to substantial limitations of occupational, educational, social and personal activities. Currently, there is no consensus regarding the treatment. Patients try many different therapies to overcome their fatigue. Although there is no consensus, cognitive behavioural therapy is seen as one of the most effective treatments. Little is known about multidisciplinary rehabilitation treatment, a combination of cognitive behavioural therapy with principles of mindfulness, gradual increase of activities, body awareness therapy and pacing. The difference in effectiveness and cost-effectiveness between multidisciplinary rehabilitation treatment and cognitive behavioural therapy is as yet unknown. The FatiGo (Fatigue-Go trial aims to compare the effects of both treatment approaches in outpatient rehabilitation on fatigue severity and quality of life in patients with chronic fatigue syndrome. Methods One hundred twenty patients who meet the criteria of chronic fatigue syndrome, fulfil the inclusion criteria and sign the informed consent form will be recruited. Both treatments take 6 months to complete. The outcome will be assessed at 6 and 12 months after the start of treatment. Two weeks after the start of treatment, expectancy and credibility will be measured, and patients will be asked to write down their personal goals and score their current performance on these goals on a visual analogue scale. At 6 and 14 weeks after the start of treatment, the primary outcome and three potential mediators—self-efficacy, causal attributions and present-centred attention-awareness—will be measured. Primary outcomes are fatigue severity and quality of life. Secondary outcomes are physical activity, psychological symptoms, self-efficacy, causal attributions, impact of disease on emotional and physical functioning, present-centred attention-awareness, life

Full Text Available In the context of competence-based teaching, this paper draws upon the model of Translation Competence (TC put forward by the PACTE group (2003 to establish a dialogue between cognitive-constructivist paradigms for translation teaching and the model of the Context-based Text Typology (MATTHIESSEN et al., 2007. In this theoretical environment, it proposes a model for the design of a Teaching Unit (TU for the development of the bilingual competence in would-be-translators.To this end, it explores translation as a cognitive, communicative and textual activity (HURTADO ALBIR, 2011 and considers its teaching from the translation task-based approach (HURTADO ALBIR, 1999. This approach is illustrated through the practical example of the design of a TU elaborated for the subject ‘Introduction to Specialized Translation’,part of the curricular grid of the program ‘Secretariado Executivo’ at Universidade Federal de Santa Catarina. Aspects such as the establishment of learning objectives and their alignment with the translation tasks composing the TU are addressed for this specific pedagogical situation. We argue for the development of textual competences by means of the acquisition of strategies derived from the Context-based Text Typology to solve problems arising from the translation of different text types and contextual configurations.

An impaired ability to suppress currently irrelevant mental-sets is a key cognitive deficit in depression. Mindfulness-based cognitive therapy (MBCT) was specifically designed to help depressed individuals avoid getting caught in such irrelevant mental-sets. In the current study, a group assigned to MBCT plus treatment-as-usual (n = 22) exhibited significantly lower depression scores and greater improvements in irrelevant mental-set suppression compared to a wait-list plus treatment-as-usual (n = 18) group. Improvements in mental-set-suppression were associated with improvements in depression scores. Results provide the first evidence that MBCT can improve suppression of irrelevant mental-sets and that such improvements are associated with depressive alleviation.

Industrial wastewater streams containing high concentrations of biorefractory materials like cyanides should ideally be treated at source. In the present work, degradation of potassium ferrocyanide (K4Fe(CN)6) as a model pollutant has been investigated using cavitational reactors with possible intensification studies using different approaches. Effect of different operating parameters such as initial concentration, temperature and pH on the extent of degradation using acoustic cavitation has been investigated. For the case of hydrodynamic cavitation, flow characteristics of cavitating device (venturi) have been established initially followed by the effect of inlet pressure and pH on the extent of degradation. Under the optimized set of operating parameters, the addition of hydrogen peroxide (ratio of K4Fe(CN)6:H2O2 varied from 1:1 to 1:30 mol basis) as process intensifying approach has been investigated. The present work has conclusively established that under the set of optimized operating parameters, cavitation can be effectively used for degradation of potassium ferrocyanide. The comparative study of hydrodynamic cavitation and acoustic cavitation suggested that hydrodynamic cavitation is more energy efficient and gives higher degradation as compared to acoustic cavitation for equivalent power/energy dissipation. The present work is the first one to report comparison of cavitation based treatment schemes for degradation of cyanide containing wastewaters. Copyright © 2014 Elsevier B.V. All rights reserved.

The underlying mechanisms of the effectiveness of mindfulness-based interventions for emotional well-being remain poorly understood. Here, we examined the potential mediating effects of cognitive reactivity and self-compassion on symptoms of depression, anxiety and stress using data from an earlier randomised controlled school trial. A moderated time-lagged mediation model based on multilevel modelling was used to analyse the data. The findings showed that post-treatment changes in cognitive reactivity and self-coldness, an aspect of self-compassion, mediated subsequent changes in symptoms of depression, anxiety and stress. These results suggest that cognitive reactivity and self-coldness may be considered as transdiagnostic mechanisms of change of a mindfulness-based intervention programme for youth.

Full Text Available Abstract Background Previous research has shown that Short Psychodynamic Supportive Psychotherapy (SPSP is an effective alternative to pharmacotherapy and combined treatment (SPSP and pharmacotherapy in the treatment of depressed outpatients. The question remains, however, how Short Psychodynamic Supportive Psychotherapy compares with other established psychotherapy methods. The present study compares Short Psychodynamic Supportive Psychotherapy to the evidence-based Cognitive Behavioral Therapy in terms of acceptability, feasibility, and efficacy in the outpatient treatment of depression. Moreover, this study aims to identify clinical predictors that can distinguish patients who may benefit from either of these treatments in particular. This article outlines the study protocol. The results of the study, which is being currently carried out, will be presented as soon as they are available. Methods/Design Adult outpatients with a main diagnosis of major depressive disorder or depressive disorder not otherwise specified according to DSM-IV criteria and mild to severe depressive symptoms (Hamilton Depression Rating Scale score ≥ 14 are randomly allocated to Short Psychodynamic Supportive Psychotherapy or Cognitive Behavioral Therapy. Both treatments are individual psychotherapies consisting of 16 sessions within 22 weeks. Assessments take place at baseline (week 0, during the treatment period (week 5 and 10 and at treatment termination (week 22. In addition, a follow-up assessment takes place one year after treatment start (week 52. Primary outcome measures are the number of patients refusing treatment (acceptability; the number of patients terminating treatment prematurely (feasibility; and the severity of depressive symptoms (efficacy according to an independent rater, the clinician and the patient. Secondary outcome measures include general psychopathology, general psychotherapy outcome, pain, health-related quality of life, and cost

A strong relation between cognition and mobility has been identified in aging, supporting a role for enhancement mobility through cognitive-based interventions. However, a critical evaluation of the consistency of treatment effects of cognitive-based interventions is currently lacking. The objective of this study was 2-fold: (1) to review the existing literature on cognitive-based interventions aimed at improving mobility in older adults and (2) to assess the clinical effectiveness of cognitive interventions on gait performance. A systematic review of randomized controlled trials (RCT) of cognitive training interventions for improving simple (normal walking) and complex (dual task walking) gait was conducted in February 2018. Older adults without major cognitive, psychiatric, neurologic, and/or sensory impairments were included. Random effect meta-analyses and a subsequent meta-regression were performed to generate overall cognitive intervention effects on single- and dual-task walking conditions. Ten RCTs met inclusion criteria, with a total of 351 participants included in this meta-analysis. Cognitive training interventions revealed a small effect of intervention on complex gait [effect size (ES) = 0.47, 95% confidence interval (CI) 0.13 to 0.81, P = .007, I 2  = 15.85%], but not simple gait (ES = 0.35, 95% CI -0.01 to 0.71, P = .057, I 2  = 57.32%). Moreover, a meta-regression analysis revealed that intervention duration, training frequency, total number of sessions, and total minutes spent in intervention were not significant predictors of improvement in dual-task walking speed, though there was a suggestive trend toward a negative association between dual-task walking speed improvements and individual training session duration (P = .067). This meta-analysis provides support for the fact that cognitive training interventions can improve mobility-related outcomes, especially during challenging walking conditions requiring higher-order executive

In addition to the classic motor symptoms, Parkinson’s disease (PD) is associated with a variety of non-motor symptoms that significantly reduce quality of life, even in the early stages of the disease. There is an urgent need to develop evidence-based treatments for these symptoms, which include mood disturbances, cognitive dysfunction, and sleep disruption. We focus here on exercise interventions, which have been used to improve mood, cognition, and sleep in healthy older adults and clinical populations, but to date have primarily targeted motor symptoms in PD. We synthesize the existing literature on the benefits of aerobic exercise and strength training on mood, sleep, and cognition as demonstrated in healthy older adults and adults with PD, and suggest that these types of exercise offer a feasible and promising adjunct treatment for mood, cognition, and sleep difficulties in PD. Across stages of the disease, exercise interventions represent a treatment strategy with the unique ability to improve a range of non-motor symptoms while also alleviating the classic motor symptoms of the disease. Future research in PD should include non-motor outcomes in exercise trials with the goal of developing evidence-based exercise interventions as a safe, broad-spectrum treatment approach to improve mood, cognition, and sleep for individuals with PD.

Potential long term effects on brain development are a concern when drugs are used to treat depression and anxiety in childhood. In this study, male juvenile rhesus monkeys (three-four years of age) were dosed with fluoxetine or vehicle (N=16/group) for two years. Histomorphometric examination of cortical dendritic spines conducted after euthanasia at one year postdosing (N=8/group) suggested a trend toward greater dendritic spine synapse density in prefrontal cortex of the fluoxetine-treated monkeys. During dosing, subjects were trained for automated cognitive testing, and evaluated with a test of sustained attention. After dosing was discontinued, sustained attention, recognition memory and cognitive flexibility were evaluated. Sustained attention was affected by fluoxetine, both during and after dosing, as indexed by omission errors. Response accuracy was not affected by fluoxetine in post-dosing recognition memory and cognitive flexibility tests, but formerly fluoxetine-treated monkeys compared to vehicle controls had more missed trial initiations and choices during testing. Drug treatment also interacted with genetic and environmental variables: MAOA genotype (high- and low transcription rate polymorphisms) and testing location (upper or lower tier of cages). Altered development of top-down cortical regulation of effortful attention may be relevant to this pattern of cognitive test performance after juvenile fluoxetine treatment.

Cognitive State Monitoring and the Design of Adaptive Instruction in Digital Environments: Lessons Learned from Cognitive Workload Assessment using a Passive Brain-Computer Interface Approach

Directory of Open Access Journals (Sweden)

Peter eGerjets

2014-12-01

Full Text Available According to Cognitive Load Theory, one of the crucial factors for successful learning is the type and amount of working-memory load (WML learners experience while studying instructional materials. Optimal learning conditions are characterized by providing challenges for learners without inducing cognitive over- or underload. Thus, presenting instruction in a way that WML is constantly held within an optimal range with regard to learners’ current working-memory capacity might be a good method to provide these optimal conditions. The current paper elaborates how digital learning environments, which achieve this goal can be developed by combining approaches from Cognitive Psychology, Neuroscience, and Computer Science. One of the biggest obstacles that needs to be overcome is the lack of an unobtrusive method of continuously assessing learners’ WML in real-time. We propose to solve this problem by applying passive Brain-Computer Interface (BCI approaches to realistic learning scenarios in digital environments. In this paper we discuss the methodological and theoretical prospects and pitfalls of this approach based on results from the literature and from our own research. We present a strategy on how several inherent challenges of applying BCIs to WML and learning can be met by refining the psychological constructs behind WML, by exploring their neural signatures, by using these insights for sophisticated task designs, and by optimizing algorithms for analyzing EEG data. Based on this strategy we applied machine-learning algorithms for cross-task classifications of different levels of WML to tasks that involve studying realistic instructional materials. We obtained very promising results that yield several recommendations for future work.

Vascular cognitive impairment (VCI) is a complex spectrum encompassing post-stroke cognitive impairment (PSCI) and small vessel disease-related cognitive impairment. Despite the growing health, social, and economic burden of VCI, to date, no specific treatment is available, prompting the introduction of the concept of a disease modifier. Within this clinical spectrum, VCI and PSCI remain advancing conditions as neurodegenerative diseases with progression of both vascular and degenerative lesions accounting for cognitive decline. Disease-modifying strategies should integrate both pharmacological and non-pharmacological multimodal approaches, with pleiotropic effects targeting (1) endothelial and brain-blood barrier dysfunction; (2) neuronal death and axonal loss; (3) cerebral plasticity and compensatory mechanisms; and (4) degenerative-related protein misfolding. Moreover, pharmacological and non-pharmacological treatment in PSCI or VCI requires valid study designs clearly stating the definition of basic methodological issues, such as the instruments that should be used to measure eventual changes, the biomarker-based stratification of participants to be investigated, and statistical tests, as well as the inclusion and exclusion criteria that should be applied. A consensus emerged to propose the development of a disease-modifying strategy in VCI and PSCI based on pleiotropic pharmacological and non-pharmacological approaches.

Predicting progression from a stage of Mild Cognitive Impairment to dementia is a major pursuit in current research. It is broadly accepted that cognition declines with a continuum between MCI and dementia. As such, cohorts of MCI patients are usually heterogeneous, containing patients at different stages of the neurodegenerative process. This hampers the prognostic task. Nevertheless, when learning prognostic models, most studies use the entire cohort of MCI patients regardless of their disease stages. In this paper, we propose a Time Windows approach to predict conversion to dementia, learning with patients stratified using time windows, thus fine-tuning the prognosis regarding the time to conversion. In the proposed Time Windows approach, we grouped patients based on the clinical information of whether they converted (converter MCI) or remained MCI (stable MCI) within a specific time window. We tested time windows of 2, 3, 4 and 5 years. We developed a prognostic model for each time window using clinical and neuropsychological data and compared this approach with the commonly used in the literature, where all patients are used to learn the models, named as First Last approach. This enables to move from the traditional question "Will a MCI patient convert to dementia somewhere in the future" to the question "Will a MCI patient convert to dementia in a specific time window". The proposed Time Windows approach outperformed the First Last approach. The results showed that we can predict conversion to dementia as early as 5 years before the event with an AUC of 0.88 in the cross-validation set and 0.76 in an independent validation set. Prognostic models using time windows have higher performance when predicting progression from MCI to dementia, when compared to the prognostic approach commonly used in the literature. Furthermore, the proposed Time Windows approach is more relevant from a clinical point of view, predicting conversion within a temporal interval
