Parent-to-child physical aggression, neighborhood cohesion, and development of childrenʹs internalizing and externalizing

Taking a risk and resilience approach, this study examined (1) whether child age moderates the association between exposure to parent–child physical aggression (PCPA) and initial levels and growth in internalizing and externalizing problems, and (2) whether neighborhood social cohesion is a protective factor for children who experience PCPA. Data came from 2810 caregivers of children aged 3–15 who participated in the Project on Human Development in Chicago Neighborhoods (PHDCN). Multilevel growth models showed that age moderated PCPAʹs association with internalizing problems, such that the association was stronger in older children than in younger children. Age also moderated PCPAʹs association with externalizing problems, such that the association was stronger in younger children than in older children. Neighborhood cohesion partially attenuated the association between PCPA and internalizing but only for older children; living in a neighborhood characterized by high cohesion mitigated levels of internalizing for maltreated children aged 11 years and older.
