There were some between-group differences by sex, race, and rate of lifetime AUD and PTSD diagnoses (see Supplemental Table 1). Compared to Class 1, which contained individuals with the least severe symptom profiles, individuals in Classes 2, 3, and 4 had between one and four higher odds of experiencing physical and sexual assault. The odds of membership in Class 4 were most highly associated with parent AUD status, especially when both parents had the disorder, at over three times that compared to the least severe class.
