Activities and social contact as antecedents to sleep onset time in U.S. adolescents.

This study evaluated adolescents' evening patterns in activities, social contact, and location to better understand antecedents to adolescents' sleep onset time (SOT). The SOT is important for sleep duration and related health outcomes. Using a nationally representative sample of 15- to 18-year-old adolescents from the American Time Use Survey (N = 10,341; 47% female; 57% white), structural equation modeling demonstrated that late SOTs mediated links between evening activities, social contact, locations, and shorter sleep durations.

Parenting Practices during Childhood and Later Adolescent Sexual Outcomes.

Limited empirical evidence exists regarding longitudinal connections between parenting during childhood and adolescents' sexual development. Using structural equation mediation modeling, this study examined how mothers' parenting practices during childhood (ages 8 to 11) directly related to adolescent sexual outcomes (ages 12 to 16) and whether relationships were mediated by parenting practices persisting over time. Two waves of data were used from a large longitudinal national sample including 687 mother-adolescent pairs (M = 10.

Latent profiles of sleep quality, financial management behaviors, and sexual satisfaction in emerging adult newlywed couples and longitudinal connections with marital satisfaction.

Emerging adult newlywed couples often experience many demands on their time, and three common problems may surface as couples try to balance these demands-problems related to finances, sleep, and sex. We used two waves of dyadic data from 1,001 emerging adult newlywed couples to identify four dyadic latent profiles from husbands' and wives' financial management behaviors, sexual satisfaction, and sleep quality: , , , and . We then examined how husbands' and wives' marital satisfaction, in relation to profile membership, varied at a later wave.

Adoption Status and Parental Investments: A Within-sibling Approach.

Recent studies have found that adoptive parents invest in their children equally or more than biological parents do. Most of these studies observed relationships across families, comparing families with adopted children to those without. In this study, alternatively, we focused on within-family comparisons to more fully isolate the relationship between biological ties and parental investments.

Adolescent interactions with family and emotions during interactions: Variation by family structure.

This study examines how often adolescents interact with family members and how adolescents feel when spending time with parents, nonresident parents, stepparents, siblings, and extended family members. Adolescents respond to whom they spend time with, and how adolescents feel during social interactions with family has implications for adolescent relationships. Family structure remains a crucial dimension of heterogeneity in adolescent life, and family systems theory suggests family structure could differentially shape adolescent emotional functioning and social development due to differences in family-level contexts.

Companionship Patterns and Emotional States During Social Interactions for Adolescents With and Without Siblings.

For decades, researchers and the general public have debated whether children without siblings differ from children with siblings in ways that are meaningful for development. One area that is underexplored in the literature on only children versus children with siblings concerns time use and emotional states in alone time and in social interactions. Resource dilution theory and the prior literature suggests that adolescent only children and adolescents with siblings may differ in some social interactions, such as in time with parents, but not in others, such as in time alone, due to offsetting effects or the universality of certain experiences among adolescents.

Adolescent caretaking of younger siblings.

Sibling interactions play important roles in socialization; however, little is known about sibling caretaking in contemporary families. This study examined the prevalence of adolescents providing care for younger siblings and the quality of care as associated with a broad spectrum of individual, microsystem, and macrosystem factors. Relying on nationally representative time diary data from the American Time Use Survey, we found that factors at multiple levels (individual, microsystem, and macrosystem) were associated with sibling caretaking.
