Self-Regulation Mitigates the Association between Household Chaos and Children's Behavior Problems.

Given the potential negative effects that early childhood behavioral problems have on later development, it is important to elucidate risk and protective factors. This study examined household chaos as a predictor of externalizing and internalizing problems among young children from low-income families. Additionally, self-regulation was examined as a moderator of the association between chaos and behavior problems. One hundred young adult mother-toddler dyads participated. Moderation analyses indicated that self-regulation buffered the association between household chaos and child behavior problems. Specifically, greater household chaos was associated with more behavior problems, but only among children with poorer self-regulation. Notably, this pattern was observed for both externalizing and internalizing problems. These findings suggest that early interventions targeting young children's self-regulation skills could help prevent behavior problems among children living in chaotic home environments.

Negative Affectivity Moderates Associations between Cumulative Risk and At-Risk Toddlers' Behavior Problems.

This study examined cumulative risk, temperament traits, and their interplay as predictors of internalizing, externalizing, and sleep problems in at-risk toddlers. Participants were 104 low-income mother-toddler dyads recruited from Women, Infants, and Children (WIC) sites in a large city. The sample was primarily African American, and mothers were 21 years of age or younger at the child's birth. The dyads were assessed when the toddlers were approximately 18 months old and again at 24 months of age. Though all toddlers were from low-income families with young mothers, the families varied in the degree to which other contextual risk factors were present. A cumulative risk index was calculated based on five contextual factors: maternal education, neighborhood dangerousness, social support, household overcrowding and single parenting. In multiple regressions, cumulative risk predicted sleep and externalizing problems. In addition, negative affectivity predicted all three domains of problem behaviors, effortful control predicted fewer externalizing problems, and surgency predicted fewer internalizing problems. Moreover, low negative affectivity buffered the association between cumulative risk and both internalizing and sleep problems. These findings suggest that it is important to consider children's temperament traits in conjunction with the constellation of family risks when designing prevention programs to reduce the prevalence of behavior problems early in life.
