PTS Criterion B (re-experiencing), 44% met Criterion C (numbing/avoidance), and 49% met Criterion D (hyperarousal). The other class with a significant combination of AUD and PTS symptoms, Class 3, endorsed fewer AUD symptoms overall, with the most commonly occurring AUD criteria being symptom 1 (larger/longer) at 32%, symptom 2 (inability to cut back) at 28%, and symptom 10 (tolerance) at 26%. The most commonly endorsed AUD symptoms across Classes 2, 3, and 4 (Class 1 had only one person meeting AUD diagnosis criteria) were symptoms 1 (alcohol is taken in larger quantities or over a longer period of time than intended) and 2 (persistent desire or unsuccessful efforts to cut down on alcohol use). Class 2 and Class 4 also shared substantial overlap between AUD symptoms 8 (recurrent use in situations that are physically hazardous) and symptom 10 (tolerance).
