Experimental: Internet-Delivered Skills Training in Affective and Interpersonal Regulation

i-STAIR specifically targets emotion dysregulation and poor interpersonal skills. i-STAIR comprises eight sessions (one hour per session, per week) and each session focuses on a particular skills deficit. In general, session-by-session topics include: (1) labelling and identifying feelings; (2) emotion management (i.e., focus on anger and anxiety); (3) distress tolerance; (4) acceptance of feelings and enhanced experiencing of positive emotions; (5) identification of trauma-based interpersonal schemas and their enactment in day-to-day life; (6) identification of conflict between trauma-generated feelings and current interpersonal goals; (7) role plays related to issues of power and control; and (8) role plays related to developing flexibility in interpersonal situations involving power differentials.

Active_comparator: Online general psychoeducation

Online general psychoeducation comprises five online sessions (one hour per session on Week 1, Week 2, Week 4, Week 6, and Week 8) where a trained research staff will provide psychoeducation to the participant for up to 1 hour, as well as three weeks of self-guided activities where the participant will work on a specific activity on their own and feedback will be provided during the online sessions. The online psychoeducation content will focus on the link between adverse childhood experiences and depression, and healthy lifestyle changes including healthy diet, exercise, and sleep.
