Predicting externalizing behaviors in typically developing toddlers at 24 months: Insights from parenting at 12 months

Early observational assessment of parent and child behaviors may identify risk factors associated with the development of early child externalizing behaviors. This study aimed to examine factors associated with child externalizing behaviors at 24-months of age, including early maternal depression, family social risk and the parent-child relationship. Using a longitudinal design in 89 mother-child dyads (n = 43 female), maternal depressive symptoms and social risk were measured post-birth, and 12-months later parent-child interaction was assessed using the Emotional Availability Scales. To assess child externalizing behaviors, a parent-report questionnaire was administered when children were 24-months old. Increased early maternal depressive symptoms (p = .03), but not higher social risk (p = 0.17), were associated with higher child externalizing behaviors in children at age 24-months. After adjusting for early maternal depressive symptoms and familial social risk, lower levels of observed maternal structuring (β = −2.60, 95 %CI = −4.56, −0.64, p = .01) and lower levels of non-hostility (β = −3.39, 95 %CI −6.64, −0.14, p = .04) when the child was 12-months old were associated with higher parent-report of externalizing behaviors. However, the child’s observed interaction behavior was not associated with the mother’s report of child externalizing behavior. Interventions targeting specific post-natal maternal mental health and early parenting behaviors may reduce the risk for the development of later child externalizing problems.
