This longitudinal study examined the development of mother-infant objective and reported sleep quality and duration in solo-mother families (i.e., mothers who decided to parent alone) in comparison to two-parent families. We recruited 134 solo mothers and 161 married mothers during pregnancy, most representing the middle to upper socioeconomic…

Personality predicts how we interact with others, what partners we have, and how happy and lasting our romantic relationships are. At the same time, our experiences in these relationships may affect our personality. Who experiences specific major relationship events, and how do these events relate to personality development? We examined this issue…

The early years of marriage are a time of significant personal and relational changes as partners adjust to their new roles, but the specific ways that spouses' personalities may change in early marriage and how these changes are associated with spouses' marital satisfaction trajectories have been overlooked. Using 3 waves of data collected over…

Common sense suggests that romantic partners tend to be interdependent in their well-being and self-esteem. The authors tested the degree to which codevelopment in romantic partners (i.e., development in similar directions) is due to mutual influence between partners or due to the effects of shared environment, using longitudinal data from 5…

Drawing from a relational developmental systems (RDS) perspective (Lerner, Agans, DeSouza, & Gasca, 2013) and data from 1,427 continuously partnered young adult and midlife mixed-sex couples over the first 5 years of the German Panel Analysis of Intimate Relationships and Family Dynamics (pairfam), this study examined the developmental course…

Although voluminous research has linked nonresident fatherhood to riskier sexual behavior in adolescence, including earlier sexual debut, neither the causality of that link nor the mechanism accounting for it has been well-established. Using data from the National Longitudinal Survey of Youth, 1979--the Young Adult Survey (CNLSY-YA), the present…

Examining children's physiological functioning is an important direction for understanding the links between interparental conflict and child adjustment. Utilizing growth mixture modeling, the present study examined children's cortisol reactivity patterns in response to a marital dispute. Analyses revealed three different patterns of cortisol…

Previous studies have demonstrated that various psychosocial risks are associated with poor cognitive functioning in children, and these risks frequently cluster together. In the current longitudinal study, we tested a model in which it was hypothesized that cumulative psychosocial adversity of mothers would have deleterious effects on children's…

This study of a cohort of 451 adolescents examined associations between trajectories of problem behaviors and the timing of entry into work, marriage, and parenthood. We used data from 12 assessments across adolescence, through emerging adulthood and into young adulthood. We employed 2-phase mixed-effects models to estimate growth in substance use…

This study used longitudinal data to examine the effects of spousal illness on depressive symptoms among middle-aged and older married individuals and the extent to which the adverse effects of illness in a spouse were mitigated by 2 psychological resources, mastery and self-esteem. Using 1,704 married participants who were 51 years of age on…

Adolescents' expectations about the timing of adult role transitions have the potential to shape their actual transitions, setting the stage for their adult lives. Although expectations about timing emerge by early adolescence, little is known about how these expectations develop across adolescence. This longitudinal study examined developmental…

In the current study, based on a sample of 1,873 adolescents between 11.4 and 20.9 years of age from the first 3 waves of the National Longitudinal Study of Adolescent Health, we investigated the longitudinal effects of future orientation on levels of and developmental changes in problem behaviors, while controlling for the effects by impulsivity;…

Adult (age 30) educational, economic, and social-emotional adjustment outcomes were investigated for participants in the Abecedarian Project, a randomized controlled trial of early childhood education for children from low-income families. Of the original 111 infants enrolled (98% African American), 101 took part in the age 30 follow-up. Primary…

Theories of socialization propose that children's ability to handle conflicts is learned at home through mechanisms of participation and observation--participating in parent-child conflict and observing the conflicts between parents. We assessed modes of conflict resolution in the parent-child, marriage, and peer-group contexts among 141 Israeli…

This study examined dyadic interrelations between episodic memory and depressive symptom trajectories of change in old and advanced old age. The authors applied dynamic models to 10-year incomplete longitudinal data of initially 1,599 married couples from the study of Asset and Health Dynamics Among the Oldest Old (M[subscript age] = 75 years at…
