Teasing out the contributions of sex, race, and economic status to trauma exposure risk is complex, and the strength of these effects varies across studies (Slack et al., 2017). The current study presents findings regarding the prevalence of trauma exposure before age 18 based on discrete types of PTSD-qualifying events: physical assault, sexual assault, witnessed violence, and non-assaultive trauma, and the prevalence of PTSD using data from the prospective cohort of a high-risk family study with well-validated measures (Bucholz et al., 1994). Our objectives are to examine, separately in Black and White youth, the prevalence of childhood trauma exposure, differential exposure as a function of parental AUD and offspring sex, and the lifetime prevalence of PTSD among trauma-exposed youth.
