Homework completion in cognitive behavioral therapy (CBT) for depression is an integral ingredient in treatment that often goes unreported. Furthermore, many studies of homework completion focus on patient adherence without considering the therapists role in reviewing and reinforcing this behavior. No studies to date have assessed the relationship between homework variables and outcomes among Latinos receiving CBT for depression. Since this population has often been difficult to engage in CBT, this study aims to assess whether homework completion and therapist review of homework are related to improved outcomes in a CBT intervention (telephone or in person) for Latinos with depression. We found that higher homework completion was significantly related to lower depression scores at the end of final treatment (as measured by PHQ-9) (B = -1.38, p < 0.01). However, the significant association of homework with depression went away when clinician review of homework was included in a subsequent step of the model (B = -0.42, p = 0.45). The number of times a clinician actively reviewed homework was still significantly related to a decrease in PHQ-9 when controlling for demographic factors (B = -1.23, p < 0.01). This study found that homework is a predictor of improved outcomes in CBT for depression but highlights the role of therapists reviewing homework as a predictor of lower depression symptoms among Spanish speaking Latinos from low socioeconomic backgrounds.

Objectives: Transdiagnostic interventions have been increasingly used in the management of a variety of mental health and substance use conditions, and in the context of chronic stress. We discuss the development and evaluation of the Integrated Intervention for Dual Problems and Early Action (IIDEA), a 10-session manualized intervention that includes cognitive therapy and mindfulness practice designed to improve symptoms of anxiety, depression, posttraumatic stress, and co-occurring substance use problems. Methods: In this secondary analysis of a randomized-controlled trial of IIDEA conducted with an international sample of immigrant Latinx in the United States and Spain, we evaluate intermediate outcomes-mindful awareness, working alliance with clinician and illness self-management-and integrate statistical findings with results from qualitative interviews with participants. Results: The IIDEA intervention group showed higher levels of mindful awareness, illness self-management, and working alliance over an enhanced treatment as usual control group (usual treatment plus scheduled assessments) and qualitative data offer insights into the importance of therapeutic alliance and integration of mindfulness practice with cognitive therapy management skills. Conclusions: Findings suggest that skills related to the studied intermediary outcomes can be helpful for Latinx immigrants experiencing circumstances of ongoing exposure to adversity and traumatic stress.

BACKGROUND:Ecological research suggests that increased access to cannabis may facilitate reductions in opioid use and harms, and medical cannabis patients describe the substitution of opioids with cannabis for pain management. However, there is a lack of research using individual-level data to explore this question. We aimed to investigate the longitudinal association between frequency of cannabis use and illicit opioid use among people who use drugs (PWUD) experiencing chronic pain. METHODS AND FINDINGS:This study included data from people in 2 prospective cohorts of PWUD in Vancouver, Canada, who reported major or persistent pain from June 1, 2014, to December 1, 2017 (n = 1,152). We used descriptive statistics to examine reasons for cannabis use and a multivariable generalized linear mixed-effects model to estimate the relationship between daily (once or more per day) cannabis use and daily illicit opioid use. There were 424 (36.8%) women in the study, and the median age at baseline was 49.3 years (IQR 42.3-54.9). In total, 455 (40%) reported daily illicit opioid use, and 410 (36%) reported daily cannabis use during at least one 6-month follow-up period. The most commonly reported therapeutic reasons for cannabis use were pain (36%), sleep (35%), stress (31%), and nausea (30%). After adjusting for demographic characteristics, substance use, and health-related factors, daily cannabis use was associated with significantly lower odds of daily illicit opioid use (adjusted odds ratio 0.50, 95% CI 0.34-0.74, p < 0.001). Limitations of the study included self-reported measures of substance use and chronic pain, and a lack of data for cannabis preparations, dosages, and modes of administration. CONCLUSIONS:We observed an independent negative association between frequent cannabis use and frequent illicit opioid use among PWUD with chronic pain. These findings provide longitudinal observational evidence that cannabis may serve as an adjunct to or substitute for illicit opioid use among PWUD with chronic pain.

Objectives

A key challenge in evaluating the impact of community-based participatory research (CBPR) is identifying what mechanisms and pathways are critical for health equity outcomes. Our purpose is to provide an empirical test of the CBPR conceptual model to address this challenge.

Methods

A three-stage quantitative survey was completed: (1) 294 US CBPR projects with US federal funding were identified; (2) 200 principal investigators completed a questionnaire about project-level details; and (3) 450 community or academic partners and principal investigators completed a questionnaire about perceived contextual, process, and outcome variables. Seven in-depth qualitative case studies were conducted to explore elements of the model not captured in the survey; one is presented due to space limitations.

Results

We demonstrated support for multiple mechanisms illustrated by the conceptual model using a latent structural equation model. Significant pathways were identified, showing the positive association of context with partnership structures and dynamics. Partnership structures and dynamics showed similar associations with partnership synergy and community involvement in research; both of these had positive associations with intermediate community changes and distal health outcomes. The case study complemented and extended understandings of the mechanisms of how partnerships can improve community conditions.

Conclusions

The CBPR conceptual model is well suited to explain key relational and structural pathways for impact on health equity outcomes.

Background

To date, health-effects research on environmental stressors has rarely focused on behavioral and mental health outcomes. That lack of research is beginning to change. Science and policy experts in the environmental and behavioral health sciences are coming together to explore converging evidence on the relationship-harmful or beneficial-between environmental factors and mental health.

Objectives

To organize evidence and catalyze new findings, the National Academy of Sciences, Engineering, and Medicine (NASEM) hosted a workshop 2-3 February 2021 on the interplay of environmental exposures and mental health outcomes.

Methods

This commentary provides a nonsystematic, expert-guided conceptual review and interdisciplinary perspective on the convergence of environmental and mental health, drawing from hypotheses, findings, and research gaps presented and discussed at the workshop. Featured is an overview of what is known about the intersection of the environment and mental health, focusing on the effects of neurotoxic pollutants, threats related to climate change, and the importance of health promoting environments, such as urban green spaces.

Discussion

We describe what can be gained by bridging environmental and psychological research disciplines and present a synthesis of what is needed to advance interdisciplinary investigations. We also consider the implications of the current evidence for a) foundational knowledge of the etiology of mental health and illness, b) toxicant policy and regulation, c) definitions of climate adaptation and community resilience, d) interventions targeting marginalized communities, and e) the future of research training and funding. We include a call to action for environmental and mental health researchers, focusing on the environmental contributions to mental health to unlock primary prevention strategies at the population level and open equitable paths for preventing mental disorders and achieving optimal mental health for all. https://doi.org/10.1289/EHP9889.

Cross-cultural variability in respondent processing of survey questions may bias results from multiethnic samples. We analyzed behavior codes, which identify difficulties in the interactions of respondents and interviewers, from a discrimination module contained within a field test of the 2007 California Health Interview Survey. In all, 553 (English) telephone interviews yielded 13,999 interactions involving 22 items. Multilevel logistic regression modeling revealed that respondent age and several item characteristics (response format, customized questions, length, and first item with new response format), but not race/ethnicity, were associated with interactional problems. These findings suggest that item function within a multi-cultural, albeit English language, survey may be largely influenced by question features, as opposed to respondent characteristics such as race/ethnicity.
