Research further suggests that trauma-related guilt is a risk factor for the later development of depression, PTSD, and substance use disorders (Andrews, Brewin, Rose, & Kirk, 2000;Kim et al, 2011;Leskela, Dieperink, & Thuras, 2002;Marlatt & Gordon, 1985;Meehan, O'Connor, Berry, Weiss, & Acampora, 1996), suggesting that guilt may underlie a range of risk factors associated with suicide risk, and may even mediate the association of depression and PTSD with suicide risk. To date, however, no studies have tested this hypothesis.…”
