Consistent with prior research, trauma exposure was positively associated with PTSD and alcohol dependence symptom counts, and FHD was positively associated with alcohol dependence symptom counts. While FHD did not moderate the associations between trauma and PTSD in the full sample, a sex‐stratified analysis showed that the association between sexual assaultive trauma and PTSD symptom counts was moderated by FHD in female participants only. One trauma type, nonsexual assaultive trauma, was associated with more TOLT excess moves made, which was shown in the sex‐stratified analysis to be driven by the female participants.
