Children under the age of 6 years are disproportionately exposed to interpersonal trauma. Research describing type and frequency of exposure to trauma among this young population is limited. Additionally, few studies have assessed the role of multiple indicators of parental functioning on children's behavior following trauma exposure. The current study was conducted with 216 ethnically and socioeconomically diverse mother-child dyads to examine the impact of maternal symptoms and parent-child functioning on child's behavior after trauma exposure. Children experienced an average of over 5 traumatic events prior to age 6 years, and mothers had experienced an average of over 13 traumatic events during their lifetime. With child's trauma history in the model, maternal depressive symptomatology (beta = .30) and parent-child dysfunction (beta = .32) each uniquely accounted for variance in children's behavioral and emotional functioning. The findings of this study underscore the need for clinical interventions that address the parent-child relationship and parental symptomatology following young children's exposure to trauma.
