Although the SSAGA or cSSAGA-A was given at all assessment timepoints, lifetime maximum DSM-5 AUD symptom count (AUDsx; range 0–11) and, for those who endorsed a Criterion A event, lifetime maximum DSM-IV PTSD Criterion B-D symptom count scores (PTSDsx; range 0–20) were assessed at each wave. In this study, we used lifetime symptom counts reported at Follow-up 3 (Mage = 22) to allow sufficient opportunity for AUDsx to present in late adolescence/young adulthood. The lifetime measure of PTSD and AUD severity was operationalized by lifetime maximum symptom counts, as opposed to time-point specific symptom severity.
