This study utilized data from the COGA prospective study, which has been ongoing since 2004. Details on data collection and procedures have previously been published (Bucholz et al., 2017). The COGA prospective study comprises offspring, both with and without alcohol use problems, from alcohol‐dependent high‐risk and community comparison families who were 12–22 years of age at enrollment and have had multimodal assessments (clinical, behavioral, neuropsychological, neurophysiological) approximately every 2 years. For the purpose of this cross‐sectional study, data from the last interview were used for each individual. Only trauma‐exposed individuals (N = 1,860) were included in this study since exposure to a traumatic event had to be present in order for an individual to be asked questions concerning PTSD symptoms. The sample was 47.1% female with a mean age of 21.9 (SD = 4.2) at the most recent interview.
