How to Use Residual Dynamic Structural Equation Modeling to Study Individual Differences and Intraindividual Variability in Experimental Factorial Designs
This article demonstrates the application of residual dynamic structural equation modeling (RDSEM) for analyzing custom contrasts in experimental factorial designs. Previous applications of RDSEM have often focused on ecological momentary assessment and daily diary data. However, RDSEM was explicitly developed for intensive longitudinal data more generally, including settings with very short time intervals between observations. Beyond these types…
Resilience factors counteract intergenerational risk for adolescent maladjustment related to family mental health history and childhood adversity
Intergenerational risk within families, stemming from familial history of mental health problems and encompassing exposure to childhood adversity, poses challenges to adolescent adjustment. However, it is important to recognize that negative developmental outcomes associated with intergenerational risk are not inevitable. To better understand resilience in this context, there is a need for studies that systematically compare different models of r…
Characterizing household food security status, perceived neighborhood food environment, and food shopping behaviors among caregivers of children in the Hispanic Community Health Study/Study of Latinos…
U.S. Hispanic/Latino households disproportionally experience food insecurity, which may intersect with their food environments and food shopping behaviors to shape diet and health, but more representative findings are needed. We identified latent classes related to household food security (HFS), food environments, and food shopping behaviors among U.S. Hispanic/Latino households, and investigated their relationships with sociodemographic characte…
Bayesian Analysis of Multi-Factorial Experimental Designs Using SEM
Latent repeated measures ANOVA (L-RM-ANOVA) has recently been proposed as an alternative to traditional repeated measures ANOVA. L-RM-ANOVA builds upon structural equation modeling and enables researchers to investigate interindividual differences in main/interaction effects, examine custom contrasts, incorporate a measurement model, and account for missing data. However, L-RM-ANOVA uses maximum likelihood and thus cannot incorporate prior inform…
A Pilot Randomized Controlled Trial of an mHealth Intervention to Improve PrEP Adherence Among Young Sexual Minority Men
Using Structural Equation Modeling in Place of Between-Subjects Analysis of Variance
This article demonstrates how to use structural equation modeling (SEMing) in place of between-subjects analysis of variance (BS-ANOVA). More specifically, this article demonstrates how to closely reproduce the F-values and p-values from ANOVA (for all main and interactions effects) using an SEM model comparison approach (i.e., χ2 difference tests between two SEMs that conform to the main and interaction effects of the null and alternative hypoth…
The role of posttraumatic cognitions in integrated treatments for co-occurring posttraumatic stress disorder and alcohol use disorder
Findings suggest that changes in posttraumatic cognitions in integrated treatments for PTSD/AUD are not solely important for symptom change but are implicated in improvements in functioning. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
A longitudinal study of cannabis use and risk for cognitive and functional decline among older adults with HIV
Repeated Measures Anova with Latent Variables to Analyze Interindividual Differences in Contrasts
Repeated measures analysis of variance (RM-ANOVA) is a broadly used statistical method to analyze data from experimental designs. RM-ANOVA aims at investigating effects of experimental conditions (i.e., factors) and predictors that affect the outcome of interest. It mainly considers contrasts that test standard main and interaction effects, even though more complex contrasts can in principle be used. Analyses, however, only focus on drawing concl…
Analyzing cross‐lag effects
Developmental researchers often have research questions about cross-lag effects-the effect of one variable predicting a second variable at a subsequent time point. The cross-lag panel model (CLPM) is often fit to longitudinal panel data to examine cross-lag effects; however, its utility has recently been called into question because of its inability to distinguish between-person effects from within-person effects. This has led to alternative form…
Integrating minority stress theory and the tripartite influence model
Eating disorders are serious mental illnesses associated with high mortality rates and health complications. Prior research has found increased rates of eating pathology in sexual minority (SM; e.g., lesbian, gay, bisexual) individuals compared to sexual majority (i.e., heterosexual) individuals. Two prominent models have potential to explain these differences: the tripartite influence model and minority stress theory. While both models separatel…
Strengthening capacity for implementation of evidence-based practices for autism in schools
Understanding the factors that influence the use of evidence-based practices (EBPs) for autism spectrum disorder (ASD) in schools is critical to the selection of effective implementation strategies to support their sustained use. The current study has 2 aims: (a) evaluate the association between school leadership profiles (undifferentiated and optimal) and fidelity of EBP implementation and (b) examine the role of implementation climate as a medi…
On Measuring and Modeling Physiological Synchrony in Dyads
Physiological synchrony within a dyad, or the degree of temporal correspondence between two individuals' physiological systems, has become a focal area of psychological research. Multiple methods have been used for measuring and modeling physiological synchrony. Each method extracts and analyzes different types of physiological synchrony, where 'type' refers to a specific manner through which two different physiological signals may correlate. Yet…
The buffering effect of peer support on the links between family rejection and psychosocial adjustment in LGB emerging adults
Lesbian, gay, and bisexual (LGB) emerging adults often seek support from their peers if they lack support from their family of origin. We predicted that peer social support would moderate the link between negative family relationships and psychosocial adjustment, such that in the context of family rejection, experiencing more peer support would predict lower levels of anxiety, depression, and internalized homonegativity (IH) and higher self-estee…
Minority Stress Predicts Depression in Lesbian, Gay, and Bisexual Emerging Adults via Elevated Diurnal Cortisol
Lesbian, gay, and bisexual (LGB) individuals report higher levels of stressful interpersonal conflicts with others because of their divergence from heterosexual social norms. In a biopsychosocial model of minority stress, we tested diurnal cortisol slopes and internalized homonegativity (IH) as two potential mechanisms linking experiences of LGB-related stress to depression. The sample consisted of 27 lesbian and bisexual young women and 35 gay a…
Coregulation of respiratory sinus arrhythmia in adult romantic partners
Questions surrounding physiological interdependence in romantic relationships are gaining increased attention in the research literature. One specific form of interdependence, coregulation, can be defined as the bidirectional linkage of oscillating signals within optimal bounds. Conceptual and theoretical work suggests that physiological coregulation should be instantiated in romantic couples. Although these ideas are appealing, the central tenet…
Early Maternal Depression and Social Skills in Adolescence
Early maternal depression is a risk factor that may have adverse effects on adolescent social skills. Although evidence indicates links between early maternal depression and social outcomes during early childhood, whether an association extends to adolescence needs further examination. We tested the possible long‐term association between early maternal depression and adolescent social skills using a national secondary dataset. A secondary objecti…
Assessing cross-partner associations in physiological responses via coupled oscillator models
A host of theoretical frameworks suggest associations of physiological signals between two individuals within a romantic relationship. However, few studies have provided empirical evidence of such associations using physiological reactivity from both partners in the dyad. In this study we use measures of respiration and heart rate from romantic partners recorded across three laboratory tasks. We examine the interrelations of each measure between …
Use of Contingent Music to Increase Academic Performance of Middle-School Students
The present research evaluated the effects of contingent access to music on the academic performance of two junior high school students with disabilities. The use of response contingent music increased the number of correct problems completed in mathematics. A replication of baseline conditions resulted in a decrease in performance. Practical applications of the procedure were discussed
