Two different SSAGA assessments were used to ascertain trauma exposure data in the current study. In all, 58.6% (N: 3875) of the EA analytic sample had trauma assessed using the SSAGA-IV35 as described previously45. Briefly, the SSAGA-IV post-traumatic stress disorder section begins by asking participants about “terrible, frightening, or horrible experiences” they may have had in their lifetime. Subsequently, they are asked about having ever experienced 21 specific potentially traumatic events, including assaultive, non-assaultive, and sexually assaultive exposures (detailed in Supplementary Table 3). Trauma exposure data on an additional 2738 participants was ascertained from earlier waves of the COGA study in which the SSAGA-II was used. The SSAGA-II asked participants if they “had ever experienced or witnessed something that is so horrible that it would be distressing or upsetting to almost anyone?” The SSAGA-II then listed some examples of potentially traumatic events and asked the participant to list up to three events. In order to use available trauma exposure data from both the SSAGA-IV and SSAGA-II, we examined a binary measure of trauma exposure (0: not exposed, 1: exposed), based
