Commitment and Motivation in a Brief DBT Intervention for Self Harm

Research suggests that individuals with Borderline Personality Disorder (BPD) experience low motivation for change (Skodal, Buckley, \& Charles, 1983). Dialectical Behavior Therapy (DBT; Linehan, 1993) includes commitment strategies that are designed to improve motivation. No studies have examined the effectiveness of these strategies. The proposed study will evaluate the efficacy of a brief DBT intervention consisting of commitment strategies plus skills training for people who self-harm. Participants will be randomly assigned to either a single orientation session of (1) commitment strategies plus psychoeducation or (2) psychoeducation. Immediately following their orientation session, all participants will be enrolled in a 90 minute group skills training session. Primary outcomes include autonomous motivation and frequency of self harm behaviours. Assessments will be conducted at six time points: baseline, after the initial orientation session, after the skills training group session, and at one week, one month, and three month follow-up
