Participants and Procedures
Participants were 41 undergraduate students, aged 18-30 (M = 20.41, SD = 2.42); 85.4% identified as women; 61.5% identified as White. Exclusion criteria for all participants included: (a) history of psychosis, intellectual disabilities, or traumatic brain injury with loss of consciousness for more than 60 minutes; (b) a score of greater than 15 on the Quick Inventory of Depression Symptoms (Rush et al., 2003); (c) severe alcohol or substance use disorder (as defined by DSM-5; American Psychiatric Association, 2013); or (d) past week suicidal ideation. As part of a larger, experimental study examining interpersonal stress and NSSI, participants were invited to the lab, where they completed a series of self-report measures followed by the interpersonal stressor interview. The interview was conducted in a private room and was administered by a trained graduate research assistant. All participants providing informed consent and all procedures were approved by the Institutional Review Board.
