However, these SCF methods assume uniform precision across subjects, disregarding variation in the number of observations, missing data issues, and the non-continuous nature of data scales. This study evaluated the predictive accuracy of the coefficients of intraindividual means and variances computed via SCF against those estimated using random effects from a Mixed-Effects Location Scale (MELS) model. A five-scenario simulation study was conducted: (1) varying numbers of observations per subject, (2) varying mean-to-variance ratios, (3) varying proportions of missing data under a missing completely at random (MCAR) assumption, (4) varying proportions of missing data under a missing at random (MAR) assumption, and (5) varying categories of ordinal scale responses. Bias and coverage of the mean levels and variability coefficients were compared across methods. In addition, a real-life dataset was used to compare the difference of means and variances between SCF and MELS approaches. Results consistently showed that the MELS model approach outperformed SCF method, yielding lower bias and higher coverage of the coefficients across all scenarios. These findings support the use of MELS for more accurate and reliable estimation of intraindividual means and variances in EMA data, highlighting its advantages for subsequent predictive modeling.</p>","PeriodicalId":48329,"journal":{"name":"Journal of Behavioral Medicine","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844695","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}

The choice of method is currently either based on theory, subjective preferences, previous general simulation studies, or the best fit of a method to the data, which does not allow evaluating the methods' performance for a specific empirical application. In this article, we illustrate how to select a method through a simulation study tailored to an empirical application. The simulation study mimics cancer data with the aim of predicting patients' quality of life. We vary sample sizes, effect sizes, correlation and interaction structures. The methods include seven parametric (OLS and ridge regression, the lasso, the all-pairs lasso, forward, backward, and hybrid stepwise regression) and four non-parametric (regression tree, random forests, bagging, and boosting). Results show that forward stepwise regression, the lasso, the all-pairs lasso, bagging, and boosting outperform the other methods throughout different design conditions. On the empirical data the all-pairs lasso performed best. In sum, this illustration can be used as an orientation for applied researchers investigating supervised machine learning methods in a specific empirical application. We offer code for R, detailed results, and sample data to replicate the analysis discussed here.</p>","PeriodicalId":48329,"journal":{"name":"Journal of Behavioral Medicine","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844728","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}

Older Veterans face unique risk factors for dementia, which makes promoting brain health a priority for the Veteran Health Administration (VHA). However, Veterans encounter barriers to implementing these recommendations, such as uncertainty about where to start, minimal personal investment, lack of social support, or negative emotional reactions to cognitive changes. We explain how principles from acceptance and commitment therapy (ACT) can address these barriers and facilitate personal engagement with brain health, and describe a group ACT intervention called Balanced Brain. We used a mixed-method, multiphase approach using clinician interviews to develop and refine the intervention, followed by pilot testing to determine feasibility and acceptability with older Veterans. Six VHA clinicians described barriers and facilitators to brain health promotion and suggested content to include in an intervention. We then recruited 21 Veterans into two group cohorts, collected data on feasibility and attrition, and assessed program satisfaction using the Client Satisfaction Questionnaire-8. Over three-quarters of Veterans attended 75% or more of group sessions, although telehealth connectivity issues were common. Veterans indicated high overall satisfaction with Balanced Brain, suggesting it as a feasible and acceptable intervention for teaching brain health principles alongside ACT coping skills to address psychosocial barriers to health behavior change.</p>","PeriodicalId":48329,"journal":{"name":"Journal of Behavioral Medicine","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844686","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}

Participants (n = 726) were recruited from 12 Catholic churches in predominantly Latino neighborhoods in and near East Los Angeles. Data collection included accelerometer-measured PA, self-reported weekly park visits, socio-demographics, history of hypertension and Type 2 diabetes, family and friend social support for PA, depression (PHQ8), stress, and measured height and weight. Multivariable linear and logistic regression models assessed associations between predictors and health outcomes. The average age was 52.3 years; 76% were women; 71% had completed high school or less; and the average BMI was 31.1 (obese). Age, female gender, and higher depressive symptoms were negatively associated with moderate-to-vigorous PA (MVPA). Being employed, greater depressive symptoms, and more safety concerns were negatively associated with park visits, while higher family support for PA was positively associated. Both accelerometer-based MVPA and self-reported park visits were associated with lower depressive symptoms. Park visits were also associated with lower odds of Type 2 diabetes, and higher family support for PA was linked with reduced odds of hypertension. These results address gaps in understanding the relationships between PA and park visits and physical and mental health among churchgoing Latino adults. Churches may serve as important venues to support family-oriented park events and promote greater use of parks for health promotion in Latino communities.
