Cross-national research suggests cultural factors affect how parents manage and perceive their children's sleep. In the United States, however, it is unclear whether documented racial/ethnic differences in these aspects of children's sleep reflect culturally distinct parental values and practices or confounding sociodemographic factors. This study uses data from the Fragile Families and Child Well Being Study to examine potential racial/ethnic differences in how parents manage and perceive the sleep of their preschool children (n = 3,068), while controlling for potential sociodemographic (e.g., family structure), environmental (e.g., number of available bedrooms), and pragmatic (e.g., parental shift work) confounds. Results suggest racial/ethnic differences exist in where children sleep, how they are put to bed, and the level of concern mothers have about their child's sleep, beyond the effect of confounding factors. These differences may reflect distinct cultural values, as well as diverse goals for family and parent-child relationships. As our country becomes increasingly heterogeneous, it is important for developmental researchers and pediatric providers to understand the various ways diversity may be reflected in family life.

Drawing from transactional models, the authors examined whether attachment security measured at age 3 (a potential source of differential vulnerability) interacts with the course of maternal depressive symptoms over an 8-year period (a potential source of differential exposure) in predicting children's self-reported depressive symptoms at age 11. Participants were from the NICHD Study of Early Child Care (N = 938). Results from growth curve modeling and analysis of covariance suggest that preschool attachment quality moderates the influence of subsequent maternal depression on children. In particular, variability in the course of maternal depressive symptoms predicted offspring depressive symptoms only among those children with an insecure attachment history. A potential protective effect of early attachment security was evident among children exposed to the most chronic levels of maternal depression. Of the children with different patterns of insecure attachments, those with behaviors classified as disorganized appeared most vulnerable to also becoming depressed if paired with a mother experiencing ongoing depressive symptoms.

Despite theoretical links between attachment quality in early childhood and subsequent internalizing symptoms, there is limited empirical evidence supporting direct effects. In this article, we test whether early attachment insecurity indirectly contributes to adolescent internalizing by increasing the likelihood of certain pathways leading to elevated symptoms (i.e., moderated mediation). Structural equation modeling and bootstrapping were used to test for moderated mediation using longitudinal data from 910 adolescents participating in the National Institute of Child Health and Human Development Study of Early Child Care (M age = 15.1; 50% female, 23% racial/ethnic minority). Among dyads with a history of an insecure attachment in early childhood, mothers' negative emotions during the transition to adolescence significantly predicted less availability during parent-adolescent interactions, which in turn increased adolescents' preoccupation with parental relationships. The same process was not evident in youth with a history of secure attachments. However, the extent to which preoccupation with parental relationships was associated with increases in internalizing symptoms depended on both attachment history and gender. Results highlight one pathway by which early attachment history may indirectly contribute to increased internalizing symptoms for girls during the transition to adolescence.
