Previous research has demonstrated associations between exposure to parental divorce and marital discord while growing up and children's psychological distress in adulthood. Few studies, however, have attempted to explain these associations. Three pathways are evaluated through which family disruption and discord may affect offspring's well-being: children's socioeconomic attainment, children's marital and relationship stability, and the quality of children's relations with parents. Using 17-year longitudinal data from two generations, results show that divorce and marital discord predict lower levels of psychological well-being in adulthood. Parent-child relationships mediate most of the associations between parents’ marital discord and divorce and children's subsequent psychological outcomes. Marital discord appears to erode children's emotional bonds with mothers, whereas both divorce and marital discord appear to erode children's emotional bonds with fathers. The results highlight the continuing importance of parent-child ties for children's well-being in early adulthood.

This chapter uses six waves of data from the Marital Instability Over the Life Course study to examine long-term trends in three aspects of spousal relationships: marital happiness, shared activities, and discord (n = 1617). Across the full sample, happiness declined gradually during the first 20 years of marriage and then stabilized. Participation in shared activities declined during the first 20 years of marriage and then increased, whereas discord declined continuously. These trends depended, however, on whether marriages ended in divorce. Overall, and contrary to some prior studies, our results suggest that marriages that remain together show little evidence of deterioration in relationship quality over the marital life course. Nevertheless, period effects were apparent, with marital relationships (irrespective of duration) becoming more troubled during the 1980s and 1990s but rebounding in 2000.

Research on the intergenerational transmission of divorce should be expanded to incorporate disrupted nonmarital cohabitations. This study (a) examined the transmission of union instability from parents to offspring using data from the National Longitudinal Study of Adolescent to Adult Health, (b) replaced binary variables (divorced vs. nondivorced) typically used in this literature with count variables (number of disrupted unions), (c) relied on independent sources for data on parents' and offspring's union disruptions to minimize same-source bias, (d) assessed the mediating role of theoretically derived variables (many not previously considered in this literature), and (e) incorporated information on discord in intact parental unions. Parent and offspring union disruptions were positively linked, with each parental disruption associated with a 16% increase in the number of offspring disruptions, net of controls. The mediators collectively accounted for 44% of the estimated intergenerational effect. Parent discord in intact unions was associated with more offspring disruptions.

Although many studies have examined associations between family structure and child outcomes, few have considered how the increase in single-parent households since the 1960s may have affected child mortality rates. We examined state-level changes in the percentage of children living with single parents between 1968 and 2010 and state-level trends in mortality among children and youth (age 19 or younger) in the United States. Regression models with state and year fixed effects revealed that increases in single parenthood were associated with small increments in accidental deaths and homicides.

In the current study the authors drew on Waves I and III from Add Health to examine the closeness of parent-adolescent relationships in married mother-stepfather families (N=1,934). They used latent class analysis to identify family constellations defined by adolescents' relationships with all of their parents: mothers, stepfathers, and biological nonresident fathers. In particular, the authors (a) identified the most common underlying patterns of adolescent-parent relationships in stepfamilies; (b) determined the background characteristics that predict membership in these groups; and (c) examined how adolescents in these groups fare with respect to depressive symptoms, delinquency, and substance use. The results indicate that adolescents' relationships can be represented with 4 latent classes. Adolescents in these classes differ on measures of adjustment, and many of these differences persist into the early adult years.

Although many studies have examined associations between family structure and children's educational achievement at the individual level, few studies have considered how the increase in single-parent households may have affected children's educational achievement at the population level. We examined changes in the percentage of children living with single parents between 1990 and 2011 and state mathematics and reading scores on the National Assessment of Educational Progress. Regression models with state and year fixed effects revealed that changes in the percentage of children living with single parents were not associated with test scores. Increases in maternal education, however, were associated with improvements in children's test scores during this period. These results do not support the notion that increases in single parenthood have had serious consequences for U.S. children's school achievement. Copyright © 2015 Elsevier Inc. All rights reserved.

This study contributes to the growing literature on factors associated with the formation of close relationships between stepfathers and stepchildren. The authors extend prior research by using nationally representative data from Add Health (N = 179) to examine how factors existing prior to stepfamily formation are associated with the quality of stepfather–adolescent ties within the first year after married stepfathers join the household. Results from structural equation models revealed that both the quality of the mother–adolescent relationship and adolescent adjustment prior to stepfamily formation were significantly associated with the perceived quality of adolescents' relationships with their stepfathers.

A variety of new measurement approaches have appeared in recent years, and the current chapter focuses on three of these: ecological momentary assessment, biomarkers, and mixed-method (qualitative and quantitative) designs. After commenting on these approaches, I turn to a perennial issue in family studies: How researchers can assess the characteristics of families as distinct from the characteristics of the individuals who make up families. Most family researchers have relied on measurement approaches developed to study individuals. Adopting a family level of analysis presents a number of challenging problems—most of which have not yet been resolved. I argue that a social network approach may be the most promising approach to study family-level characteristics, especially if researchers view families as spanning multiple households.

This study employs nationally representative data on adolescents and their stepfathers (n = 2085) from the National Longitudinal Study of Adolescent Health (Add Health) to examine factors associated with positive stepfather-stepchild relationships in married stepfamilies. Results reveal substantial variability in the perceived quality of adolescents’ relationships with stepfathers. Structural equation models using Wave I data reveal that close relationships with mothers and close ties between mothers and stepfathers are positively related to the perceived quality of adolescents’ relationships with stepfathers. Longitudinal models using Waves I and II do not yield definitive results but suggest that the direction of influence runs in both directions, with the mother-child relationship and the stepfather-stepchild relationship mutually reinforcing one another. We identify a number of other factors that are associated with positive stepfather-stepchild ties, as well as a few factors that may be less consequential than previously thought. Most of the correlates of positive stepfather-stepchild relationships are similar for boys and girls; for Whites, Blacks, and Hispanics; and for stepfamilies of various durations.
