Rates of traumatic exposures in COGA’s prospective study have been previously described (Bucholz et al., 2017; McCutcheon et al., 2017; Meyers et al., 2019). Briefly, exposure to nonassaultive trauma was the most prevalent (N = 1,479; 79.5%) followed by nonsexual assaultive trauma (N = 916; 49.2%) and sexual assaultive trauma (N = 364; 19.6%). Rates of sexual trauma were greater among female participants (N = 306 vs. N = 58), and rates of nonsexual assaultive trauma were greater among male participants (N = 616 vs. N = 300). 36.7% of individuals who reported experiencing at least one of the three trauma types endorsed at least one PTSD symptom, and 56.1% endorsed at least one DSM‐IV alcohol dependence. See Table 1 for descriptive statistics.
