Outcomes of the linking exercise for advancing daily stress (Leads) management and resilience randomized pilot trial in African American adolescents and families
BACKGROUND: Previous research has examined the deleterious impact of racial stress on African Americans' mental and physical health; however, few interventions have focused on utilizing culturally salient protective factors to buffer the effect of racial stress on physical health outcomes. PURPOSE: This pilot feasibility trial assessed the preliminary impact of Linking Exercise for Advancing Daily Stress (LEADS) Management and Resilience, a cultu…
An R Shiny App for Sensitivity Analysis for Latent Growth Curve Mediation
Mechanisms of behavior change are the processes through which interventions are hypothesized to cause changes in outcomes. Latent growth curve mediation models (LGCMM) are recommended for investigating the mechanisms of behavior change because LGCMM models establish temporal precedence of change from the mediator to the outcome variable. The Correlated Augmented Mediation Sensitivity Analyses (CAMSA) App implements sensitivity analysis for LGCMM …
Latent Class Mediation
Latent class mediation modeling is designed to estimate the mediation effect when both the mediator and the outcome are latent class variables. We suggest using an adjusted one-step approach in which the latent class models for the mediator and the outcome are estimated first to decide on the number of classes, then the latent class models and the mediation model are jointly estimated. We present both an empirical demonstration and a simulation s…
Development of an Ethnic Identity Measure for Americans of Middle Eastern and North African Descent
BACKGROUND: Southeast Michigan is home to the second largest Middle Eastern and North African (MENA) US population. There is increasing interest in understanding correlates of psychosocial outcomes and health behaviors in this growing population. One potentially important health correlate is ethnic identity (EI). This paper reports the development, validity, and initial correlates of a new measure of MENA identity named the MENA-IM. METHODS: We u…
The Effects of Sample Size on the Estimation of Regression Mixture Models
Regression mixture models are a statistical approach used for estimating heterogeneity in effects. This study investigates the impact of sample size on regression mixture’s ability to produce “stable” results. Monte Carlo simulations and analysis of resamples from an application data set were used to illustrate the types of problems that may occur with small samples in real data sets. The results suggest that (a) when class separation is low, ver…
Regression Mixture Models
Regression mixture models are increasingly used as an exploratory approach to identify heterogeneity in the effects of a predictor on an outcome. In this simulation study, we tested the effects of violating an implicit assumption often made in these models; that is, independent variables in the model are not directly related to latent classes. Results indicate that the major risk of failing to model the relationship between predictor and latent c…
Evaluating Differential Effects Using Regression Interactions and Regression Mixture Models
Research increasingly emphasizes understanding differential effects. This paper focuses on understanding regression mixture models, a relatively new statistical methods for assessing differential effects by comparing results to using an interactive term in linear regression. The research questions which each model answers, their formulation, and their assumptions are compared using Monte Carlo simulations and real data analysis. The capabilities …
Context‐Dependent Pathways of the Transmission of Risk from Communities to Individuals
Research has consistently documented the role of environmental risk factors in the onset of delinquent behavior among youth. Less is known about the processes through which these contextual risks are translated to individual youth behavior. The aim of the current study is to examine the role of family risk factors in the transmission of community risk. Data was obtained from a nationally representative sample of over 30,000 middle school youth an…
Finite Mixtures for Simultaneously Modeling Differential Effects and Nonnormal Distributions
Regression mixture models have been increasingly applied in the social and behavioral sciences as a method for identifying differential effects of predictors on outcomes. While the typical specification of this approach is sensitive to violations of distributional assumptions, alternative methods for capturing the number of differential effects have been shown to be robust. Yet, there is still a need to better describe differential effects that e…
Heterogeneity in Parent‐reported Social Skill Development in Early Elementary School Children
Despite known risks associated with aberrant social skill development, there has been a relative dearth of literature on typical developmental changes in social skills over time. In this study, we examine systematic changes in social skills from kindergarten (typical age of 5–6 years) to third grade (typical age of 8–9 years), and focus on systematic heterogeneity across these developmental trajectories. Data came from the N ational H ead S tart—…
Factor Structures for Aggression and Victimization Among Women Who Used Aggression Against Male Partners
Theories and measures of women's aggression in intimate relationships are only beginning to be developed. This study provides a first step in conceptualizing the measurement of women's aggression by examining how well three widely used measures (i.e., the Revised Conflict Tactics Scales (CTS), the Sexual Experiences Survey [SES], and the Psychological Maltreatment of Women Inventory [PMWI]) perform in assessing women's perpetration of and victimi…
The association of self-efficacy and parent social support on physical activity in male and female adolescents
Previous research has shown that cognitive factors may account for the relationship between interpersonal factors and health behaviors. Given these findings, the current study sought to further explore the direct and indirect relationship between parental social support and adolescent physical activity (PA).Data were collected from 1,421 sixth graders (73% Black, 54% females, 71% on free or reduced lunch) in South Carolina. Measures for emotional…
Community‐level effects of individual and peer risk and protective factors on adolescent substance use
The association between community‐aggregated levels of individual and peer risk and protective factors and prevalence of adolescent substance use was examined in repeated cross‐sectional data among youth in 41 communities ranging in population from 1,578 to 106,221. The association between community levels of these risk and protective factors in 2000 and substance use 2 years later was examined by using within‐cohort analyses (e.g., sixth grade i…
Assessing differential effects
Developmental scientists frequently seek to understand effects of environmental contexts on development. Traditional analytic strategies assume similar environmental effects for all children, sometimes exploring possible moderating influences or exceptions (e.g., outliers) as a secondary step. These strategies are poorly matched to ecological models of human development that posit complex individual by environment interactions. An alternative con…
Using Multilevel Mixtures to Evaluate Intervention Effects in Group Randomized Trials
There is evidence to suggest that the effects of behavioral interventions may be limited to specific types of individuals, but methods for evaluating such outcomes have not been fully developed. This study proposes the use of finite mixture models to evaluate whether interventions, and, specifically, group randomized trials, impact participants with certain characteristics or levels of problem behaviors. This study uses latent classes defined by …
Multilevel Analysis of a Measure of Community Prevention Collaboration
This study assesses a measure of community‐wide collaboration on prevention‐specific activities (i.e., prevention collaboration ) in context of the theory of community change used in the Communities That Care prevention system. Using data from a sample of 599 community leaders across 41 communities, we examined the measure with regard to its factor structure, associations with other concurrent community‐level measures, and prediction by individua…
Using community and family risk and protective factors for community‐based prevention planning
Research has identified risk and protective factors related to adolescent substance use using individual‐level data, but it is uncertain whether or not these relationships exist when data are aggregated to a community level. Using data from adolescents in 41 communities, this article found that most community and family risk and protective factors, measured at the community level, predicted student prevalences of tobacco, alcohol, and marijuana u…
Assessing community effects on adolescent substance use and delinquency
This study investigates community‐level prediction of adolescent substance use and problem behaviors using ratings by community leaders to assess the effects of four risk factors on levels of drug use and problem behaviors. Three questions are examined: (a) Can psychometrically sound measures of community leader perceptions of risk factors in their community be developed?; (b) What is the relationship between community leader ratings of the commu…

Effects of psychoeducation for offenders in a community correctional facility
The present study provided a randomized outcome evaluation of the psychoeducational component of the EQUIP program. The psychoeducational curriculum was implemented in a community correctional facility for adult felony offenders. The psychoeducational curriculum is designed to remedy offenders' delays in moral judgment maturity, social cognitive distortions, and social skill deficiencies. The participants were 316 felony offenders, 71% male, aged…
Assessing the Unit of Measurement for School Climate through Psychometric and Outcome Analyses of the School Climate Survey
This study examines the appropriate unit of theory of school climate while simultaneously conducting a psychometric analysis of a modification of the School Climate Survey for an elementary school population. A conceptualization of school climate as an individual-level property unique to each school participant is compared to the idea that climate is a characteristic of the school with school participants having the role of informants. These two …
The Effects of Developmentally Appropriate Practices on Academic Outcomes Among Former Head Start Students and Classmates, Grades 1–3
The educational ideology of Developmentally Appropriate Practices (DAP) in childhood education is influential, despite remarkably little empirical study. This article relates DAP to changes in achievement and receptive language among former Head Start children and classmates in Grades 1–3 (including between 1,564 and 4,764 children in 869 to 1,537 classrooms). The authors applied multilevel growth curve modeling techniques to estimate overall DAP…
