Abstract: Informed by models of resilience in military families, we explored factors theorized to be associated with social-emotional resilience and risk among young military-connected children. Our secondary analysis of cross-sectional data from 199 military-connected families (n = 346 parents) with at least one preschool-age child in the home (n = 199) led to the empirical identification of two distinct clusters: families with children demonstrating healthy social-emotional functioning and those showing indicators of less healthy social-emotional functioning when compared to the first group. We then identified factors associated with membership in each cluster to determine which deployment and parental well-being variables were salient for young child adjustment. Parent psychological symptoms, parenting, child behavior, and parent-child relationships were measured by parent report and observed interaction. Children with healthier social-emotional functioning were found to be residing with families experiencing less stress and distress. The importance of maternal trauma history is highlighted in our study, as elevated maternal symptoms across all three posttraumatic stress disorder symptom domains were associated with child social-emotional risk. Basic family demographic characteristics did not contribute significantly to the cluster distinctions, nor did military service factors such as active duty, reserve or veteran status, military rank or parent deployment history. These findings are important as the results deemphasize the importance of military service characteristics and highlight the importance of parent well-being when considering social-emotional risk and resilience of young children within military families.
