RESUMEN

OBJECTIVES: Limited research exists that outlines the predictive relevance of the treatment components of prolonged exposure (PE) for post-traumatic stress disorder (PTSD) on PTSD and depression symptom outcomes. The goal of the present study was to investigate relations between participant completion of breathing retraining, in vivo exposure, and imaginal exposure exercises and symptom outcomes. METHODS: A total of 58 participants completed a trial of PE as part of a larger trial on peer involvement and treatment adherence. Diagnostic and self-report measures were completed throughout treatment. Participants also recorded weekly completion of breathing retraining, in vivo exposure, and imaginal exposure exercises. Pearson correlations and hierarchical regression analyses were used to investigate relations between average weekly treatment component completion and treatment outcomes, controlling for relevant variables. RESULTS: Although breathing retraining and in vivo exposures were associated with PTSD outcomes in the correlational findings, use of breathing retraining, in vivo exposures, and imaginal exposures were not reliably associated with PTSD symptom outcomes when controlling for other variables in the regression analysis. However, when investigating changes in comorbid symptoms of depression, greater use of breathing retraining was associated with decreased symptoms of depression at posttreatment. CONCLUSIONS: Present findings demonstrate the differential relations between participation in various PE treatment components and posttreatment symptom outcomes. The importance of breathing retraining in addressing comorbid depressive symptoms is discussed, with emphasis on potentially increasing relaxation and positive activities more broadly to encourage further treatment benefits.

RESUMEN

BACKGROUND: There are presently a number of eating disorder treatment interventions that have a research-evidence base to support their effectiveness. However, rates of attrition and treatment outcomes demonstrate that there is no one-size fits all for the treatment of eating disorders. Narrative therapy is a promising, but under-researched, intervention for the treatment of eating disorders (EDs). The aim of this study was to conduct a narrative synthesis of the literature to explore the content and use of narrative therapy in the treatment of EDs. METHOD: Data were extracted from 33 eligible included studies following systematic search of five data bases. Data included aims and objectives, sample characteristics, treatment details and components of narrative therapy, which informed the narrative synthesis. The study is reported according to the Preferred Reporting items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Narrative therapy interventions for EDs consisted of several components including the narrative worldview; unpacking the problem story; finding, thickening the meaning and performance of stories hidden by the problem story; and safety considerations. A notable proportion of the extracted articles discussed components of unpacking problem stories, and finding and re-authoring openings (or unique outcomes) that were hidden by problematic stories. Relatively fewer papers discussed the processes by identity shifts were performed or lived out, including in the eating practices of those with a lived ED experience. Furthermore, few papers addressed how therapists established client safety within the narrative framework when working with EDs. CONCLUSION: This narrative synthesis found that narrative practitioners utilise a variety of narrative therapy techniques in working with individuals with a lived ED experience. The current literature has emphasis on specific narrative therapy techniques used in ED treatments, with some aspects of the narrative worldview and safety considerations left undiscussed. Additional research is needed to explore how identity shifts in narrative therapy are performed and lead to measurable behavioural changes, and to consider how safety considerations can be established within the narrative worldview. There are a number of psychological therapies for eating disorders that have research evidence-base. These treatments, however, do not work for everyone as indicated by drop-out rates and eating disorders running a severe and enduring course for some people. Narrative therapy is a therapeutic intervention that has been reported as a promising intervention for people with an eating disorder. The focus of narrative therapy is to engage the person in finding identities hidden by problem-saturated identities and in the performance of these hidden identities. In this review, we have explored the use of narrative therapy for eating disorders to identify what aspects of this therapy are currently being used and which components are less referenced in the literature. Findings from this study support the need for further research into narrative therapy components in the treatment of eating disorders, particularly how hidden identities are performed and safety considerations are integrated into this therapeutic intervention.

RESUMEN

Purpose: Although Cardiac Rehabilitation (CR) implementation models recommend delivery of any CR treatment component, Sub-Saharan Africa (SSA) constitutes only 17% of globally available CR programs. The aims of this review were to assess the benefits of employing any CR treatment modality in SSA, and evaluate if this approach should be encouraged in this resource-constrained region. Methodology: Records were identified electronically via CINAHL, MEDLINE, Cochrane library, African journal online, PubMed, Web of science and google scholar, and grey literature was hand-searched. Articles reporting effectiveness of any CR treatment modality were included if participants had any cardiovascular disease and if the study was conducted in SSA. Quality assessment for each enrolled study was done using Downs and Black (1998) checklist and data was extracted using a modified standard tool. Results: Searches identified 1666 records, 24 full text articles were examined and 10 were included for the review; 60%, 30% and 10% of the enrolled studies were done in South Africa, Nigeria and Benin respectively. The studies implemented exercise, psychosocial and education treatment modalities of CR, and the approach of delivery was either comprehensive or modified. Comprehensive CR and delivery of combined aerobic and resistance exercises improved physical (13%, p=0.001), social (40%, p=0.001) and mental aspects of quality of life and reduced anxiety (-12%, p<0.05) and depression (-6%, p<0.001) respectively. Comprehensive CR and aerobic training both reduced systolic blood pressure (range of mean reduction [RMR] -6 to -14mmHg), diastolic blood pressure (RMR -4 to -6mmHg) and resting heart rate (RMR -7 to -17bpm). Overall, all types of exercises showed a 1-5ml.kg-1.min-1 increase in peak oxygen consumption. Conclusion: The findings support delivery of exercise treatment modality and comprehensive delivery of CR in SSA. However, efficacy of independent implementation of education and psychosocial therapeutic components of CR remains unclear; hence the need for further investigations.

RESUMEN

OBJECTIVE: While adherence is an important factor influencing the effectiveness of internet interventions, many studies operationalize adherence only by the number of sessions and do not report adherence to specific treatment components. The goal of this study was to investigate adherence to treatment components as well as outcome in outpatients and self-referred participants who participated in an internet intervention targeting anxiety. METHOD: Outpatients (N = 50) were compared to self-referred (N = 37) participants and a matched outpatient waitlist sample (based on nearest neighbor matching): Using t-test and χ2 tests adherence to treatment components based on the number of completed exercises was compared between participant groups. A 2 × 2 repeated measures ANOVA was used to compare pre-to post symptom change between participant groups. Primary measures included the Generalized Anxiety Disorder Scale-7 (GAD-7) and the Mini Social Phobia Inventory (Mini-SPIN). Using nonparametric bootstrap analyses number of sessions and adherence to treatment components were investigated as potential mediators of the relationship between participant group and outcome. Finally, predictors of adherence to treatment components in outpatient participants were investigated using LASSO and logistic regression. RESULTS: Self-referred participants were more adherent than outpatient participants, however the groups did not differ significantly in outcome. Outpatient participants who adhered to relaxation showed greater improvement during the waiting period than the matched outpatient waitlist sample. The effect of participant group on outcome was mediated via adherence to exposure and number of sessions. CONCLUSIONS: In internet interventions adherence to treatment components differs between participant groups and has a mediating effect on treatment outcome. Therefore, it should be fostered, especially when participants are not self-referred. In line with these findings more studies should investigate relevant participant characteristics in more depth.

RESUMEN

Use of supporting materials in cognitive behavioural therapy (CBT) is widely advocated, and homework increases effectiveness. The study aimed to identify materials most frequently used by CBT therapists to support CBT for depression, and those perceived clinically most effective. Questionnaires were sent to 3665 accredited CBT therapists asking about their use of resources commonly described in CBT manuals, and their views on effectiveness. Of 3665 approached by post/email, 994 (27%) responded. Another 33 completed the questionnaire via the study website. 818/1027 (80%) of respondents were accredited practitioners who deliver one-to-one therapy. Symptom measures, lists of problems/goals, activity schedules, behavioural activation diaries/plans, and case formulation worksheets were used "frequently" or "very frequently" by over 85% of respondents. Sleep diaries and computerised CBT were used least. Most resources were used within and between sessions. Activity schedules, behavioural activation diaries/plans, case formulation worksheets, thought records, and resources to support the identification of conditional beliefs were regarded as most effective. Symptom measures, sleep diaries, and computerised/online materials were considered only moderately effective. Therapists use a wide range of materials to support individual CBT. For delivering CBT, technology-enabled approaches should incorporate a range of materials to enable therapists to tailor treatment effectively.

RESUMEN

This study investigated the effect of "dose" and the components of Cognitive Behavioral Therapy (CBT) on treatment effects. It is a secondary analysis of the ACTION (Assessment of Cognitive Therapy Instead of Neuroleptics) trial which investigated CBT for people with schizophrenia spectrum disorders that chose not to take antipsychotic medication. Using instrumental variable methods, we found a "dose-response" such that each CBT session attended, reduced the primary outcome measure (the PANSS total score) by approximately 0.6 points (95% CI -1.20 to -0.06, p = 0.031). This suggests that length of therapy is important for those that receive CBT in the absence of antipsychotic medication. Secondly, using principal stratification we examined the process variables that modified treatment effects. Findings revealed that those who received a longitudinal formulation in the first 4 sessions of CBT had poorer treatment effects than those who did not, however this finding was not statistically significant (95% CI -37.244, 6.677, p = 0.173). However, it is important to note that these findings were evident in an exploratory analysis with a small sample. Future larger scale studies are needed to help understand components of effective treatment.

RESUMEN

No studies to date have examined the effect of counselor techniques on smoking cessation over the course of treatment. To address this gap, we examined the degree to which the use of specific Acceptance and Commitment Therapy (ACT) counseling techniques in a given session predicted smoking cessation reported at the next session. The data came from the ACT arm of a randomized controlled trial of a telephone-delivered smoking cessation intervention. Trained raters coded 139 counseling sessions across 44 participants. The openness, awareness and activation components of the ACT model were rated for each telephone counseling session. Multilevel logistic regression models were used to estimate the predictive relationship between each component during any given telephone session and smoking cessation at the following telephone session. For every 1-unit increase in counselors' use of openness and awareness techniques there were 42% and 52% decreases in the odds of smoking at the next counseling session, respectively. However, there was no significant predictive relationship between counselors' use of activation techniques and smoking cessation. Overall, results highlight the theoretical and clinical value of examining therapists' techniques as predictors of outcome during the course of treatment.
