Cognitive Behavioral Therapy: Strategies for Enhancing Treatment Engagement.

Treatment engagement, crucial in cognitive behavioral therapy (CBT) outcomes, centers on consistent implementation of between-session homework. This article explores clinical features affecting engagement, including challenges related to psychosocial stressors and negative core beliefs. Empirical evidence supports the positive causal and correlational relationship between homework and symptom reduction. Recent studies highlight the role of patient beliefs and suggest a collaborative approach in homework design. The CBT account of treatment engagement emphasizes clinician behavior, patient beliefs, and task specificity. The comprehensive model of homework in CBT involves careful planning, collaborative review, and addressing patient-specific challenges, providing valuable clinical insights.

Symptom Reduction and Engagement in a Cognitive-Behavioral Mobile Phone App: A Study of User Profiling to Determine Prognostic Indicators.

OBJECTIVE: We investigated the presence of latent transition profiles in a sample of users of a cognitive-behavioral mental health app for the general population. Users' baseline characteristics were used as predictors of the profiles. The role of engagement with the app in the transition profiles was examined. METHOD: A total of 541 users completed the Patient Health Questionnaire-9 and the General Anxiety Disorder-7 when started using the app and 30 days after. Random-Intercept Latent Transition Analysis was implemented to identify users' profiles and transition patterns as classes. The age of the users and the Emotional Self-Awareness Scale-Revised (ESAS-R) were used as predictors of class membership at baseline. The Homework Rating Scale-Mobile Application (HRS-MA; as a measure of engagement) was used as a predictor of class membership at 30 days of app use. RESULTS: A 3-class solution was obtained according to the severity of symptoms (from mild to moderately severe). Age and ESAS-R predicted class membership initially; the higher the age and ESAS-R, the higher the probability of starting using the app with lower distress levels. The HRS-MA predicted class membership at 30 days of app use; the higher the engagement for more symptomatic and younger users, the higher the probability of improvement. However, older users tended to engage less. CONCLUSION: Our findings underpin the relevance of easily accessible digital interventions for young adults with mild to moderate mental health problems. Further studies and developments are required to enhance these apps for older cohorts.

The relationships among working alliance, group cohesion and homework engagement in group cognitive behaviour therapy for social anxiety disorder.

OBJECTIVE: Few studies have investigated the role of generic relational factors, such as group cohesion and working alliance, in group cognitive behaviour therapy (CBT) for social anxiety disorder (SAD). The aim of this study was to examine the temporal associations among working alliance, group cohesion, and an index of a CBT-specific factor, homework engagement, as correlates of fear of negative evaluation and symptoms of social anxiety in group CBT for SAD. METHOD: There were 105 participants with a diagnosis of social anxiety disorder who were randomly assigned to 12 sessions of group imagery-enhanced or standard CBT. Participants completed measures at various time points during the 12-session interventions, and the relationship among variables was examined through random-intercept cross-lagged panel models. RESULTS: Group cohesion was significantly associated with social anxiety symptoms at the end of treatment, however there was no significant relationship with working alliance. Greater homework engagement predicted lower social interaction anxiety, but only during mid-treatment. CONCLUSION: The results highlight the importance of supporting group cohesion and maximising homework engagement during core components of social anxiety treatment such as behavioural experiments.

Therapist competence, homework engagement, and client characteristics in CBT for youth depression: A study of mediation and moderation in a community-based trial.

OBJECTIVE: Prior studies of Cognitive Behavioral Therapy (CBT) have focused on the quantity and quality of clients' homework completion and only rarely have considered the role of therapist competence. METHODS: The present study examined (a) therapist competence across the entire process of integrating homework into CBT, including the review, design, and planning of tasks; (b) homework engagement, including client appraisals of the difficulty and obstacles encountered in task completion using the Homework Rating Scale - Revised (HRS-II); (c) pre-post symptom reduction as the index of outcome; and (d) considered client factors such as suicide risk in a community-based trial for adolescent depression. Trained independent observers assessed therapist competence and engagement with homework at two consecutive sessions of CBT for N = 80 young people (Mage = 19.61, SD = 2.60). RESULTS: Significant complementary mediation effects were obtained; there was an indirect mediation effect of HRS-II Beliefs (b = 1.03, SE B = 0.42, 95% BCa CI [0.35, 2.03]) and HRS-II Perceived Consequences on the Competence-Engagement relationship (b = 0.85, SE B = 0.31, 95% BCa CI [0.39, 1.61]). High levels of suicidal ideation were also shown to moderate this relationship. CONCLUSIONS: The present findings contribute to the growing body of CBT process research designed to examine the complex interrelationships of client and therapist variables, in a manner that reflects the actual process of therapy, and advances beyond studies of isolated predictors of symptom change.

Homework as a driver of change in psychotherapy.

BACKGROUND AND OBJECTIVES: The utilization of Between-Session Homework (BSH) holds a longstanding tradition in the field of psychotherapy. Significantly, it serves as a pivotal catalyst for change within behavioral and cognitive-behavioral therapies, and has also garnered endorsement within psychodynamic and humanistic-experiential therapies. While our current conceptualization of BSH is characterized by assimilation and integration, diversity prevails in how BSH is incorporated into the treatment plan, spanning various therapy stages, thus necessitating a customized therapist-client interpersonal dynamic. Far from being a panacea, the employment of BSH emerges as a highly sophisticated and intricate clinical methodology, demanding a high degree of therapist proficiency and competence to facilitate client engagement. METHODS: In this introductory paper, we present an issue of the Journal of Clinical Psychology: In Session that exemplifies the diverse modalities through which BSH can be integrated into clinical practice across various client demographics and within distinct psychotherapeutic paradigms. We place specific emphasis on the pivotal role of BSH and its interplay with proposed mechanisms of change throughout the course of treatment. RESULTS: Initially, we provide an overarching view of the subject and expound on empirical research substantiating the efficacy of BSH in psychotherapy. Subsequently, we delve into strategies for adeptly integrating and monitoring BSH within clinical practice. CONCLUSIONS: Our primary objectives encompass affording readers a more lucid comprehension of (1) the content and nature of homework; (2) the influence of BSH on treatment outcomes; and (3) the ways through which therapists can foster client engagement with BSH. Finally, we introduce the six papers comprising this issue.

Predictors of homework engagement in group CBT for social anxiety: client beliefs about homework, its consequences, group cohesion, and working alliance.

OBJECTIVE: Group cognitive behaviour therapy (CBT) for social anxiety disorder (SAD) is effective, but little data exist on generic relational components of the therapeutic process, such as group cohesion and therapy alliance, and central CBT-specific components such as homework engagement, beliefs, and perceived consequences. The aim of this study was to investigate the relationships between homework, group cohesion, and working alliance during group CBT for social anxiety disorder. METHOD: Participants (N = 105) with SAD engaged in 12 sessions of group CBT. Measures of homework, working alliance, and group cohesion were completed at multiple points throughout treatment. Random-intercept cross-lagged panel models were used to evaluate the prospective relationships between measures. RESULTS: Prospective relationships between the homework outcomes did not vary throughout the treatment period, with the only significant relationships seen between the random intercepts ("trait" levels). Homework beliefs were a significant negative predictor of future group cohesion, but only in mid- to late-treatment. Homework consequences and working alliance were significantly and positively predictive of each other throughout therapy. CONCLUSION: Early homework engagement is associated with higher engagement throughout therapy. Working alliance and homework engagement are important to bolster early in group CBT.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12616000579493..

Machine Learning Predictions of Oil Yields Obtained by Plastic Pyrolysis and Application to Thermodynamic Analysis.

Chemical recycling via thermal processes such as pyrolysis is a potentially viable way to convert mixed streams of waste plastics into usable fuels and chemicals. Unfortunately, experimentally measuring product yields for real waste streams can be time- and cost-prohibitive, and the yields are very sensitive to feed composition, especially for certain types of plastics like poly(ethylene terephthalate) (PET) and polyvinyl chloride (PVC). Models capable of predicting yields and conversion from feed composition and reaction conditions have potential as tools to prioritize resources to the most promising plastic streams and to evaluate potential preseparation strategies to improve yields. In this study, a data set consisting of 325 data points for pyrolysis of plastic feeds was collected from the open literature. The data set was divided into training and test sub data sets; the training data were used to optimize the seven different machine learning regression methods, and the testing data were used to evaluate the accuracy of the resulting models. Of the seven types of models, eXtreme Gradient Boosting (XGBoost) predicted the oil yield of the test set with the highest accuracy, corresponding to a mean absolute error (MAE) value of 9.1%. The optimized XGBoost model was then used to predict the oil yields from real waste compositions found in Municipal Recycling Facilities (MRFs) and the Rhine River. The dependence of oil yields on composition was evaluated, and strategies for removing PET and PVC were assessed as examples of how to use the model. Thermodynamic analysis of a pyrolysis system capable of achieving oil yields predicted using the machine-learned model showed that pyrolysis of Rhine River plastics should be net exergy producing under most reasonable conditions.

Integrating between-session homework in psychotherapy: A systematic review of immediate in-session and intermediate outcomes.

[Correction Notice: An Erratum for this article was reported in Vol 60(3) of Psychotherapy (see record 2023-99100-002). In the article (https://doi.org/10.1037/ pst0000488), the number of included studies in Figure 2 omitted two studies that were added to the literature synthesis. Therefore, the following has been added to the Reports excluded box in Figure 2: A further two studies were added to the research synthesis by author knowledge. All versions of this article have been corrected.] This article reviews the evidence for between-session homework (BSH) in individual psychotherapy. Whereas previous reviews have demonstrated a positive association between-client compliance with BSH and distal treatment outcomes; here, we pay particular attention to therapist behaviors that may promote client engagement with BSH assessed as immediate (in-session) and intermediate (session-to-session) outcomes, and moderators of these effects. For our systematic review, we identified 25 studies with 1,304 clients and 118 therapists, mostly on cognitive behavioral therapy such as exposure-based treatments with depression and anxiety disorders. A box score approach was utilized to summarize findings. Results for immediate outcomes were mixed but neutral. Results for intermediate outcomes were positive. Presenting a convincing rationale, being flexible in collaboratively designing, planning, and reviewing homework tasks in accordance with the clients' goals, aligning BSH with the clients' takeaways from the session and providing a written summary of homework and rationale, are some therapist behaviors that can promote client engagement with BSH. We conclude with research limitations, training implications, and therapeutic practices. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Clinician experiences of homework in couples and family therapy: A survey of perceived impact on the working alliance.

The process of engaging clients in homework assignments has been studied extensively in research settings, but rarely have the challenges in the implementation of the science been considered in couples and family therapy. A survey was conducted of 226 clinicians regarding (1) their experience of homework adherence (quantity and quality) with couple and family clients, and (2) their experience of the impact of homework non-completion (IHN) on the working alliance. Clinicians working with families reported less overall homework quantity and quality. However, across both couples and family clients, more negative IHN was reported among clinicians experiencing less homework quantity, both in terms of IHN bond (couple ρ = 0.71, p < 0.001; family ρ = 0.78, p < 0.001) and IHN agreement (couples ρ = 0.25, p < 0.001; ρ = 0.19, p = 0.006), and among clinicians with fewer years of clinical experience (r = 0.19, n = 136, p < 0.05). The present findings suggest that, in the context of couples and family therapy, there is a risk of perceived negative IHN on the working alliance. There would be merit to future investigations examining the processes of facilitating homework engagement within the context of a strong working alliance.

Does the working alliance mediate the therapist competence-outcome relationship in cognitive behavior therapy for depression?

Objective: This study examined whether the working alliance mediated the effect of therapist competence on subsequent depression symptomology during Cognitive Behavioral Therapy (CBT). We also tested the potential moderation effect of alliance on subsequent depressive symptomology, based on participants' cognitive aptitude.Method: A total of 86 sessions were coded as the prediction interval across 50 patient-therapist dyads (age M = 39.22, SD = 8.78; 76% female). While accounting for prior depression, competence, and alliance levels, predictors were assessed early treatment (session 1; n = 45 sessions), mid-treatment (session 12; n = 41 sessions), and depressive symptomology was assessed at the subsequent session to the predictor assessments to investigate within-session variability of process variables.Results: Mediation analysis revealed that the effect of early treatment therapist competence on symptom change was mediated by alliance (indirect effect: ß = -.17, 95% percentile bootstrap CI [-.32, -.01]). The positive association involving early treatment alliance and next session outcome was conditional upon low cognitive aptitude levels.Conclusions: Our result offers preliminary support for alliance as a mediator of the effect of competence, and that alliance-outcome relations vary as a function of client aptitude. These novel findings require replication and extension.

Thermodynamic feasibility of shipboard conversion of marine plastics to blue diesel for self-powered ocean cleanup.

Collecting and removing ocean plastics can mitigate their environmental impacts; however, ocean cleanup will be a complex and energy-intensive operation that has not been fully evaluated. This work examines the thermodynamic feasibility and subsequent implications of hydrothermally converting this waste into a fuel to enable self-powered cleanup. A comprehensive probabilistic exergy analysis demonstrates that hydrothermal liquefaction has potential to generate sufficient energy to power both the process and the ship performing the cleanup. Self-powered cleanup reduces the number of roundtrips to port of a waste-laden ship, eliminating the need for fossil fuel use for most plastic concentrations. Several cleanup scenarios are modeled for the Great Pacific Garbage Patch (GPGP), corresponding to 230 t to 11,500 t of plastic removed yearly; the range corresponds to uncertainty in the surface concentration of plastics in the GPGP. Estimated cleanup times depends mainly on the number of booms that can be deployed in the GPGP without sacrificing collection efficiency. Self-powered cleanup may be a viable approach for removal of plastics from the ocean, and gaps in our understanding of GPGP characteristics should be addressed to reduce uncertainty.

Observing the Working Alliance in Videoconferencing Psychotherapy for Alcohol Addiction: Reliability and Validity of the Working Alliance Inventory Short Revised Observer.

The coronavirus disease-2019 (COVID-19) pandemic has affected the mental health and alcohol consumption of individuals. Videoconferencing psychotherapy has become a fundamental mode of treatment for people with alcohol use disorders. However, there are still doubts about its effectiveness and the therapeutic relationship. The working alliance is considered a foundation of effective practice in cognitive behavioral therapy (CBT). Observer measurements of the working alliance have demonstrated reliability and meaningful associations with the reduction of symptoms. However, translations of instruments to evaluate the working alliance and examine its construct have not previously been conducted for online psychotherapy for alcohol addiction. This study aimed for the cross-cultural adaptation of the Working Alliance Inventory-Short Form-Observer (WAI-SR-O) for Brazil and the evaluation of its reliability and evidence of its validity in videoconferencing psychotherapy for alcoholism. The WAI-SR-O was applied by pairs of observers for the evaluation of the working alliance in 19 recorded sessions of videoconferencing psychotherapy of 10 clients with a diagnosis of alcohol addiction. The sessions were also evaluated by the therapist (WAI-T) and client (WAI-C). The WAI-SR-O shows a moderate inter-rater intraclass correlation coefficient (ICC = 0.67) for the general scale, higher ICC for the goals and bond subscales, and a moderate value for the task subscale. The internal consistency was good (a = 0.86). The results show low but significant correlations among the goals and bond subscales of the WAI-SR-O and the general, goals, and bond scales of the WAI-T. No correlations were found with the WAI-C. As the literature points out, the client, therapist, and observer versions of the WAI evaluated the alliance differently, requiring further study. The WAI-SR-O proved to be a reliable and valid measurement for the evaluation of the working alliance in videoconferencing psychotherapy for alcohol addiction, becoming an important tool for the study of the working alliance in telepsychotherapy.

Editorial: Applications of Cognitive and Behavioral Therapy in Response to COVID-19.

The corona virus (COVID-19) continues to have a devastating health, economic, and social impact on our local and international communities. Cognitive and Behavioral Therapies (CBTs), as a family of therapies that posit cognitive, behavioral, emotional, and interpersonal change processes in the understanding and successful treatment of mental health disorders, have risen to the challenge. This special issue represents contributions from CBT experts on the impact on psychopathology, new assessment methods, adaptations of integrated behavioral health, telehealth, psychology training, and discusses a public health framework. The issue includes a series of articles offering guidance for the clinician on interventions for those impacted by trauma, CBT for youth and families, and telehealth for psychotic spectrum disorders and group therapy for social anxiety.

Engagement with smartphone-delivered behavioural activation interventions: a study of the MoodMission smartphone application.

BACKGROUND: Despite increased research interest in smartphone mental health applications (MHapps), few studies have examined user engagement and its determinants. MoodMission is a MHapp that targets low mood and anxiety via evidence-based techniques including behavioural activation (BA). AIMS: The present study aimed to investigate (i) whether BA interventions delivered with visual psychoeducation had greater engagement than BA interventions delivered with solely written psychoeducation, (ii) whether BA interventions targeting mastery would have greater engagement than those targeting pleasure, and (iii) the relationship between level of engagement and MHapp benefit. METHOD: Participants downloaded MoodMission and completed activities and within-app evaluations over a 30-day period. Data from 238 MoodMission users were analysed via multi-level modelling and linear regression. RESULTS: The average number of app-based activities completed was 5.46 and the average self-reported engagement level was in the low to moderate range. As hypothesized, higher levels of engagement significantly predicted more positive activity appraisal. CONCLUSIONS: The results suggest that BA technique beliefs are involved in MHapp engagement and future research examining user appraisals of techniques is warranted.
