These occupational stressors represent trauma embedded within healthcare delivery systems, rather than solely an individual-level burden, with downstream effects on systems of care that affect patients (e.g., communication, adherence, disclosure, trust), workforce retention, healthcare quality, and health equity. Despite these detrimental outcomes, there are currently no universal STS prevention programs or institutional guidelines, which limits the dissemination of STS training among medical interpreters. The present practice-oriented study describes a community-based participatory research (CBPR) partnership between university researchers and a community organization housing a Spanish–English interpreter training program serving predominantly Latine patients. We discuss the partnership building process using a CBPR logic model describing the most salient factors influencing the initiative relating to the context, group dynamics, systemic intervention, and anecdotal outcomes. We discuss a three-component, trauma-informed systemic intervention for preventing STS in medical interpreters that emerged from this collaboration, which includes psychoeducation and skills training, routine monitoring, and structured processing groups. We describe anecdotal lessons learned from this collaboration relating to the use of a CBPR approach, the importance of reflexivity and flexibility, ways of further developing the systemic intervention, and the tension between CBPR and neoliberalism in academia. Finally, implications, limitations, and future directions are provided, including the need for quantitative/qualitative evaluations of the described integrated STS prevention framework for medical interpreter training programs.</p>","PeriodicalId":48329,"journal":{"name":"Journal of Behavioral Medicine","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147785903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used a Bayesian Model Averaging (BMA) approach to network analysis to identify the most probable structures and to evaluate conditional dependence underlying symptomology in 110 cardiovascular patients diagnosed with a Thoracic Aortic Aneurysm (TAA). Symptoms of general and disease-specific distress were assessed using the Depression Anxiety Stress Scales (DASS-21) and the Cardiac Anxiety Questionnaire-Attention Subscale (CAQ-A). Bayesian Model Averaging (BMA) and Bayes Factors (BF) were used to inform model selection and quantify model uncertainty. We present both the psychological symptom network with the highest posterior probability—and thus the best predictive utility and the BMA network, which produces tests of conditional dependence and independence which average over all structures and thus are not conditional on the other variables present in a single selected reference model. However, the posterior distribution showed variability in plausible complexity, or the number of parameters in the network structure. Utilizing BMA is especially protective in cases of structural uncertainty and high complexity. Of the 171 possible edges, 19 edges had strong evidence for inclusion. Notably, two edges connected the general and cardiac anxiety scales: DASS_7 (worry about experiencing panic) to CAQ_3 (chest discomfort wakes me up at night) and DASS_9 (Aware of Heart Symptoms) to CAQ_2 (racing heart wakes me up at night).

As in LCA, indicator variables are used to measure such concepts. We use twelve indicators of JDR, and five indicators of mental health.

We also identified three mental health states: poor, moderate, and good. Among those in moderate health, transitions to good health were more common for respondents in the 'Dream job' state and less common for respondents in the 'Tough job' state.

Researchers primarily focus on determining whether the intervention is more effective than the control condition at post-treatment and whether these effects are sustained or change over time. This paper presents Latent Change Models (LCMs) as a practical approach for analyzing randomized pretest-posttest-follow-up (RPPF) trials, directly estimating discrete changes between timepoints and intervention-control group differences. The utility of LCMs is demonstrated through an application to the STAR (Supporting Treatment Adherence Regimens) trial, a pediatric randomized behavioral clinical trial aimed at improving adherence to anti-seizure medications (ASMs) among children with new-onset epilepsy. The results of the trial analyzed via an LCM are contrasted with the results as analyzed by an ANCOVA, a longitudinal linear mixed-effects model, and a latent growth curve model. The tutorial and application to the STAR trial demonstrate that LCMs offer notable strengths, including the ability to estimate discrete changes over time, control for baseline variability in the outcome, and incorporate all longitudinal data within a single, parsimonious model.

Traditionally, Poisson and Negative Binomial models have been commonly employed, but they may not always be the most optimal choices, particularly when dealing with data with an abundance of zeroes, which can be effectively modeled using zero-inflated and zero-altered (hurdle) models. Additionally, U-shaped distributions where the data are clustered around both ends-low and high counts-with fewer occurrences in the middle, cannot be adequately captured by traditional approaches and further complicate the analysis. This paper critically examines the widespread use of zero-inflated Poisson (ZIP) and zero-inflated negative binomial (ZINB) models in the context of adolescent substance use data, identifying their potential limitations. Using a dataset from a smoking study of 1263 adolescents who reported smoking behavior across eight waves, we analyzed the sparse count outcome \"Days Smoked in the Past Month,\" with covariates such as sex, age, and GPA recorded at each wave. Through a comprehensive evaluation of smoking behavior count outcomes-employing model identification via the Kolmogorov-Smirnov (KS) test, validation through confirmation studies, and regression analysis guided by Akaike Information Criterion (AIC). The range of models covered includes: ZIP, Poisson hurdle (PH), ZINB, negative binomial hurdle (NBH), zero-inflated negative binomial with fixed r (ZINB-r), negative binomial hurdle with fixed r (NBH-r), zero-inflated beta-binomial (ZIBB), beta-binomial hurdle (BBH), zero-inflated beta-binomial with fixed n (ZIBB-n), beta-binomial hurdle with fixed n (BBH-n), zero-inflated beta-binomial with fixed alpha and beta (ZIBB-ab), beta-binomial hurdle with fixed alpha and beta (BBH-ab), zero-inflated beta negative binomial (ZIBNB), and beta negative binomial hurdle (BNBH). Our study demonstrates the superior model fitting and regression analysis capabilities of the ZIBB and BBH models. Notably, our findings reveal the effectiveness of the ZIBB model in capturing the U-shaped distribution observed in real-world data. This underscores the importance of exploring a wider range of models beyond ZIP and ZINB for count data analysis. This study advocates for the broader application of these more sophisticated models in behavioral medicine, with the goal to enhance the accuracy and reliability of research outcomes.</p>","PeriodicalId":48329,"journal":{"name":"Journal of Behavioral Medicine","volume":" ","pages":"353-371"},"PeriodicalIF":2.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12973045/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145655788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We demonstrate an illustrative example using data from individuals convicted of sexual crimes, incarcerated, and completing psychotherapy programs based on cognitive behavioral therapy. Our findings highlight the utility of 2W-LCSM in capturing both within-person change and its predictive relationship with recidivism. Results indicate a significant reduction in cognitive distortions post-treatment, with latent change scores emerging as a significant predictor of reduced sexual crime recidivism.
