Abstract

The quality of early caregiving may partially shape brain structure and circuits involved in regulating emotions, including the frontal cortex, affecting vulnerability to the development of psychopathology and maladaptation. Given the profound impact of child maltreatment (CM) on psychological and neural development, we tested whether CM alters the pathways linking mother-adolescent relationship, frontal cortex, and adult outcomes. We used structural equation modeling to investigate whether CM history affected the association between mother-child relationship quality during early adolescence, frontal lobe volume in adulthood, and adult internalizing and externalizing symptomatology and competence. Participants from a longitudinal high-risk, low-income sample included 48 adults with a history of CM and 40 adults without such history ( M = 30.0 years).

RESULTS showed that greater frontal lobe volume predicted higher levels of adult adaptive functioning and fewer adult internalizing symptoms but showed no relation to adult externalizing symptoms. Frontal lobe volume significantly mediated the effect of adolescent maternal relationship quality on both adult internalizing symptoms and adult adaptive functioning, but only for individuals with no maltreatment history. Given the observed relationship between frontal lobe volume and healthy adult functioning across the full sample, it will be important to identify protective factors in maltreated individuals that foster frontal lobe development.
