A growing literature suggests that adversity is associated with later altered brain function, particularly within the corticolimbic system that supports emotion processing and salience detection (e.g., amygdala, prefrontal cortex [PFC]). Although neighborhood socioeconomic disadvantage has been shown to predict maladaptive behavioral outcomes, particularly for boys, most of the research linking adversity to corticolimbic function has focused on family-level adversities. Moreover, although animal models and studies of normative brain development suggest that there may be sensitive periods during which adversity exerts stronger effects on corticolimbic development, little prospective evidence exists in humans. Using two low-income samples of boys (n = 167; n = 77), Census-derived neighborhood disadvantage during early childhood, but not adolescence, was uniquely associated with greater amygdala, but not PFC, reactivity to ambiguous neutral faces in adolescence and young adulthood. These associations remained after accounting for several family-level adversities (e.g., low family income, harsh parenting), highlighting the independent and developmentally specific neural effects of the neighborhood context. Furthermore, in both samples, indicators measuring income and poverty status of neighbors were predictive of amygdala function, suggesting that neighborhood economic resources may be critical to brain development.

ObjectiveThis study examines intergenerational continuities in relationship instability, general relationship quality, and intimate partner violence (IPV) between mothers and adolescents.BackgroundA growing body of literature has observed similarities in relationship quality between parents and their adult offspring. Less attention has focused on whether intergenerational continuities are present in adolescent relationships.MethodUsing age 3, 5, 9, and 15 data from the Fragile Families and Child Wellbeing birth cohort study (N=3,162), the authors examined associations between maternal reports of relationship instability, general quality, and IPV in early and middle childhood and similar adolescent reports at age 15. Variations based on timing and persistence of exposures were considered.ResultsIn general, exposures to low-quality maternal relationships were associated with higher risk of forming adolescent partnerships and lower relationship quality. Intergenerational links in quality were predominantly construct-specific, consistent with observational learning processes. Adolescents exposed to maternal relationships of poor general quality in middle childhood were less likely to report high-quality relationships themselves, and those exposed to any maternal physical IPV victimization during childhood were more likely to perpetrate IPV in their own relationships. Exposure to maternal relationship instability in both early and middle childhood was associated with more adolescent romantic partners.ConclusionThe study illuminates additional pathways through which healthy and unhealthy relationships are reproduced across generations.

This article examines the prevalence, predictors and outcomes of unmarried mothers' repartnering patterns following a nonmarital birth. Results indicate that, within five years after a birth, approximately two-thirds of unmarried mothers end their relationship with the focal child's biological father, and more than half of these mothers enter new partnerships. Among those who repartnered, 60 percent of mothers formed unions with men who had higher economic capabilities than their former partners, 20 percent formed unions with men of similar capabilities, and 20 percent formed unions with men who had lower capabilities. This pattern holds for both nonresidential and coresidential unions. Our findings are consistent with marriage market, learning and evolutionary biology theories about union formation, and they provide support for qualitative evidence that unmarried mothers have high standards for new partners. While many mothers find new partners who seem to offer a higher level of economic security, many other mothers remain unpartnered, likely due (at least in part) to the limited pool of potential partners with relatively high levels of economic promise.

We used data from the Fragile Families and Child Wellbeing Study to examine how couple relationship quality and parental engagement are linked over children's early years--when they are infants, toddlers, and preschoolers. Our sample included 1,630 couples who were coresident over Years 1-3 and 1,376 couples who were coresident over Years 3-5 (1,196 over both periods). Overall, we found that better relationship quality predicted greater parental engagement for both mothers and fathers--especially in the infant to toddler years; in contrast, we found little evidence that parental engagement predicted future relationship quality. In general, married and cohabiting couples were similar in how relationship quality and parenting were linked.

Data from the Fragile Families and Child Wellbeing Study (N = 4,176) are used to examine family structure transitions and maternal parenting stress. Using multilevel modeling, we found that mothers who exit coresidential relationships with biological fathers or enter coresidential relationships with nonbiological fathers reported higher levels of parenting stress than mothers in stable coresidential relationships. Mothers who enter coresidential relationships with biological fathers reported lower levels of parenting stress than mothers who remain single. Mothers' resources, especially their relationships with biological fathers, accounted for most of the associations between transitions and parenting stress, with posttransition resources being more important than pretransition resources. Mothers with high levels of education were less affected by transitions than mothers with less education.

Using the Fragile Families and Child Wellbeing Study, we examine the association between parental major depressive and generalized anxiety disorders and child behavior problems across family types: married, cohabiting, involved nonresident father, and noninvolved nonresident father. Among 3-year-olds in all families, maternal anxiety/depression is associated with increased odds of anxious/depressed, attention deficit, and oppositional defiant disorders (N = 2,120). Paternal anxiety/depression has no significant association with these problem behaviors; father's illness, however, exacerbates anxious/depressed behaviors in young children if both parents are ill and he is coresident. The findings underscore the importance of maternal mental health for child well-being and suggest that a negative interaction between parent illnesses is most likely when parents and children share the same disorder.

We examine whether parents rely on principles of equity or equality in making judgments about nonresident fathers' obligations and rights. The data are taken from the first wave of the Fragile Families and Child Wellbeing Study. The analysis sample includes 4,304 new mothers and 3,414 new fathers. Results indicate that fathers perceive obligations and rights as independent concerns (equality principle), whereas mothers see obligations and rights as linked (equity principle). The findings raise questions about previous claims that women favor equality principles, whereas men favor equity principles. They also underscore the importance of considering gender differences in perceptions of fathers' rights and obligations in designing effective child support and visitation policies.

The interaction of welfare and child support regulations has created a situation in which child support policy's incentives that discourage unwed fatherhood tend to be stronger than its incentives that encourage unwed motherhood. This suggests that more stringent child support enforcement creates incentives that reduce the likelihood of nonmarital childbearing, particularly among women with a significant chance of needing public assistance in the event of a nonmarital birth and their male partners. We investigate this hypothesis with a sample of women from the Panel Study of Income Dynamics, to which we add information on state child support enforcement. We examine childbearing behavior between the ages of 15 and 44 before marriage and during periods of non-marriage following divorce or widowhood. The estimates indicate that women living in states with more effective child support enforcement are less likely to bear children when unmarried, especially if they are young, never-married, or black. The findings suggest that improved child support enforcement may be a potent intervention for reducing nonmarital childbearing.
