Research on divorce during the past decade has focused on a range of topics, including the predictors of divorce, associations between divorce and the well-being of children and former spouses, and interventions for divorcing couples. Methodological advances during the past decade include a greater reliance on nationally representative longitudinal samples, genetically informed designs, and statistical models that control for time-invariant sources of unobserved heterogeneity. Emerging perspectives, such as a focus on the number of family transitions rather than on divorce as a single event, are promising. Nevertheless, gaps remain in the research literature, and the review concludes with suggestions for new studies.

Research on Divorce: Continuing Trends and New Developments

We review research on families and health published between 2000 and 2009 and highlight key themes and findings from innovative, methodologically rigorous studies. Whereas research in prior decades focused primarily on whether family structure affects child and adult health, contemporary research examines the contextual and processual factors that shape for whom, for which outcomes, and under what conditions families affect mental and physical health. We discuss how family structure, transitions, and processes within families of origin affect children's health over the life course. We then examine the effects of marital status, transitions, and quality for adult health. We point out limitations in current research, discuss implications of recent findings for policy, and highlight theoretical and methodological directions for future research.

This article reviews recent research (1999 – 2009) on the effects of parenthood on wellbeing. We use a life course framework to consider how parenting and childlessness influence well-being throughout the adult life course. We place particular emphasis on social contexts and how the impact of parenthood on well-being depends on marital status, gender, race/ethnicity, and socioeconomic status. We also consider how recent demographic shifts lead to new family arrangements that have implications for parenthood and well-being. These include stepparenting, parenting of grandchildren, and childlessness across the life course.

Parenthood, Childlessness, and Well-Being: A Life Course Perspective.

This article reviews areas of advancement over the past decade in our understanding of remarriage and stepfamilies and suggests promising new directions for future work. Profound shifts in the demographic context of family life motivate central themes in recent scholarship on remarriage and stepfamilies, including the diversity and complexity of stepfamily structures and processes, the consequences of multiple partnerships for adults and children, and potential selectivity in the characteristics of individuals entering remarried families and stepfamilies. Despite challenges to further progress, I argue that remarriage and stepfamilies offer strategic opportunities to investigate many core concerns of family scholars.

Remarriage and stepfamilies: Strategic sites for family scholarship in the 21st century.

Over the past decade, the linkages between marriage and child well-being have attracted the attention of researchers and policy makers alike. Children's living arrangements have become increasingly diverse and unstable, which raises important questions about how and why family structure and stability are related to child outcomes. This article reviews new research on this topic, emphasizing how it can inform policy debates about the role of marriage in reducing poverty and improving child outcomes. It also pays special attention to new scholarship on unmarried, primarily low-income families, the target of recent federal marriage initiatives, to appraise the potential contributions of family research to ongoing policy discussions.

Relationship Churning in Emerging Adulthood: On/Off Relationships and Sex with an Ex.

This study highlights the heterogeneity in two-parent families and examines how adolescents fare when they reside in simple two-parent, blended, and stepfamilies. Using the National Longitudinal Study of Adolescent Health (N= 1,769), we find that shared biological children in blended families have worse outcomes than children in simple two-parent families, even though they reside with both of their biological parents. These differences occur for academic performance, delinquency, school detachment, and depression. Current explanations in the family literature do not account for the poorer outcomes of shared children in blended families. We suggest that the presence of half-siblings creates a unique family situation that is not accurately represented in the current family literature.

Young adults' romantic relationships are often unstable, commonly including breakup-reconcile patterns From the developmental perspective of emerging adulthood exploration, such relationship "churning" is expected; however, minor conflicts are more common in churning relationships Using TARS data (N = 792), we test whether relationship churning is associated with more serious conflict: physical violence and verbal abuse Those who are stably broken up (breakup only - no reconciliation) are similar to those who are stably together in their conflict experiences In contrast, churners (ie, those involved in on-off relationships) are twice as likely as those who are stably together or stably broken up to report physical violence and half again as likely to report the presence of verbal abuse in their relationships; this association between churning and conflict holds net of a host of demographic, personal, and relationship characteristics These findings have implications for better understanding unhealthy relationship behaviors

Relationship Churning, Physical Violence, and Verbal Abuse in Young Adult Relationships.

Significance This study demonstrates the causal impact of a poverty reduction intervention on early childhood brain activity. Data from the Baby’s First Years study, a randomized control trial, show that a predictable, monthly unconditional cash transfer given to low-income families may have a causal impact on infant brain activity. In the context of greater economic resources, children’s experiences changed, and their brain activity adapted to those experiences. The resultant brain activity patterns have been shown to be associated with the development of subsequent cognitive skills. Early childhood poverty is a risk factor for lower school achievement, reduced earnings, and poorer health, and has been associated with differences in brain structure and function. Whether poverty causes differences in neurodevelopment, or is merely associated with factors that cause such differences, remains unclear. Here, we report estimates of the causal impact of a poverty reduction intervention on brain activity in the first year of life. We draw data from a subsample of the Baby’s First Years study, which recruited 1,000 diverse low-income mother–infant dyads. Shortly after giving birth, mothers were randomized to receive either a large or nominal monthly unconditional cash gift. Infant brain activity was assessed at approximately 1 y of age in the child’s home, using resting electroencephalography (EEG; n = 435). We hypothesized that infants in the high-cash gift group would have greater EEG power in the mid- to high-frequency bands and reduced power in a low-frequency band compared with infants in the low-cash gift group. Indeed, infants in the high-cash gift group showed more power in high-frequency bands. Effect sizes were similar in magnitude to many scalable education interventions, although the significance of estimates varied with the analytic specification. In sum, using a rigorous randomized design, we provide evidence that giving monthly unconditional cash transfers to mothers experiencing poverty in the first year of their children’s lives may change infant brain activity. Such changes reflect neuroplasticity and environmental adaptation and display a pattern that has been associated with the development of subsequent cognitive skills.

The impact of a poverty reduction intervention on infant brain activity

We investigate the link between premarital cohabitation and trajectories of subsequent marital quality using random effects growth curve models and repeated measures of marital quality from married women in the NLSY-79 (N = 3,598). We find that premarital cohabitors experience lower quality marital relationships on average, but this is driven by cohabitors with nonmarital births. Premarital cohabitors without nonmarital births report the same marital quality as women who did not cohabit before marriage. Nonmarital childbearing is more strongly associated with lower subsequent marital quality for White women than for Black or Hispanic women. Marital quality declines at similar rates for all couples regardless of cohabitation or nonmarital childbearing status. These findings are robust to numerous alternative model specifications.
