Characterizing Social Communication Difficulties in Young Children within a Longitudinal Ecological Systems Framework.

Social communication difficulties are a transdiagnostic risk factor for psychopathology. However, few studies have examined prospective risk for social communication difficulties in young children within an ecological systems framework. Our sample was 251 parent-child dyads assessed during pregnancy, postpartum, and toddlerhood (child ages 1 and 2). We leveraged observer ratings of child behavior, parent-reported questionnaires, and geocoded data. We examined prospective risk factors for social communication difficulties at ages 1 and 2, including at the level of the child (gestational age), family (household income, maternal mental health, maternal-child bonding), and neighborhood (neighborhood resources). Fewer neighborhood resources were associated with more social communication difficulties at age 1, but only among dyads with impaired maternal bonding. Lower gestational age, lower household income, and impaired maternal bonding were associated with more child social communication difficulties at age 2. Fewer neighborhood resources were also related to more social communication difficulties at age 2, specifically among families with low household incomes. Findings provide insight into families who may benefit from early intervention to reduce transdiagnostic risk for child psychopathology across ecological systems, including efforts to target maternal bonding and poverty.
