Identifying the Contributions of Maternal Factors and Early Childhood Externalizing Behavior on Adolescent Delinquency.

We examined whether childhood externalizing group subtypes were uniquely related to maternal depression and victimization and whether these subtypes differentially predicted adolescent delinquency. Data were drawn from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN) consortium (N = 1091; 51.3% female, 52.2% African American). Latent class analysis indicated three groups at age 4 (titled "well-adjusted," "hyperactive/oppositional," and "aggressive/rule-breaking"). Caregiver victimization and depression significantly predicted group membership such that aggressive/rule-breaking group had higher levels of maternal depression and victimization although the well-adjusted group had higher levels of maternal victimization relative to the hyperactive/oppositional group. Further, membership in higher externalizing groups at age four is associated with greater risk of adolescent delinquency at age 16. These findings underscore the need to address maternal risk factors in the treatment of childhood disruptive behavior and provide evidence of the continuity of disruptive behaviors from early childhood to adolescence.

Contribution of schools to mental health and resilience in recently immigrated youth.

Given the high risk of psychopathology among recently immigrated Central American adolescents, the aim of this study was to examine several putative protective factors: parental attachment, peer attachment, and school engagement. Based on prior research with other immigrant groups, parental and peer attachment were expected to correlate with reduced mental health problems, increased prosocial behavior, and increased resilience. However, the current study sought to add to existing data regarding putative protective factors by testing the incremental contribution of school engagement over and above existing support from parents and peers. The present study included 78 recently immigrated adolescents from Central America who were enrolled at a public high school for recent immigrants. Findings revealed that school engagement made a significant, positive contribution to mental health and resilience for youth above and beyond the effects of parental and peer attachment. Specifically, school engagement (i.e., subscales Behavioral Engagement, Emotional Disaffection, and Active Behavioral Disaffection) uniquely contributed to models predicting externalizing psychopathology, prosocial behavior, and resilience. In sum, the findings of this study preliminarily suggest that fostering school engagement may have protective effects for recently immigrated youth above and beyond traditional (i.e., peer, family) supports.

Childhood socioeconomic status and childhood maltreatment: Distinct associations with brain structure.

The present study examined the relationship between childhood socioeconomic status (SES), childhood maltreatment, and the volumes of the hippocampus and amygdala between the ages of 25 and 36 years. Previous work has linked both low SES and maltreatment with reduced hippocampal volume in childhood, an effect attributed to childhood stress. In 46 adult subjects, only childhood maltreatment, and not childhood SES, predicted hippocampal volume in regression analyses, with greater maltreatment associated with lower volume. Neither factor was related to amygdala volume. When current SES and recent interpersonal stressful events were also considered, recent interpersonal stressful events predicted smaller hippocampal volumes over and above childhood maltreatment. Finally, exploratory analyses revealed a significant sex by childhood SES interaction, with women's childhood SES showing a significantly more positive relation (less negative) with hippocampus volume than men's. The overall effect of childhood maltreatment but not SES, and the sex-specific effect of childhood SES, indicate that different forms of stressful childhood adversity affect brain development differently.
