Efficient Exploration Of Many Variables And Interactions Using Regularized Regression, Tyson S. Barrett, Ginger Lockhart

Psychology Faculty Publications

The prevention sciences often face several situations that can compromise the statistical power and validity of a study. Among these, research can (1) have data with many variables, sometimes with low sample sizes, (2) have highly correlated predictors, (3) have unclear theory or empirical evidence related to the research questions, and/or (4) have difficulty selecting the proper covariates in observational studies. Modeling in these situations is difficult—and at times impossible—with conventional methods. Fortunately, regularized regression—a machine learning technique—can aid in exploring datasets that are otherwise difficult to analyze, allowing researchers to draw insights from these data. Although many of these …

The Influence Of Father And Mother Involvement On Adolescent Internalizing And Externalizing Symptoms, Chelsie D. Temmen

Department of Psychology: Dissertations, Theses, and Student Research

Although much research has highlighted the importance of parents to adolescent well-being, very little work has focused on father involvement. Pleck’s model of father involvement introduces a framework to examine fathers’ influences on development. This study investigated Pleck’s model of father involvement and its relevance to describing mother involvement, examined the relations between mother and father involvement and adolescent internalizing and externalizing symptoms, and explored the moderating role of adolescent gender on the relationships between mother and father involvement and adolescent internalizing and externalizing symptoms.

Data came from 52 intact heterosexual families where the mother, father, and adolescent child (ages …

Adolescence is a complex period of concurrent mental and physical development that facilitates adult functioning at multiple levels. Despite the growing number of neuroimaging studies of cognitive development in adolescence focusing on regional activation patterns, there remains a paucity of information about the functional interactions across these participating regions that are critical for cognitive functioning, including memory. The current study used structural equation modeling (SEM) to determine how interactions among brain regions critical for memory change over the course of adolescence. We obtained functional MRI in 77 individuals aged 8–16 years old, divided into younger (ages 8–10) and older (ages …
