ABSTRACT

PURPOSE: The current randomized controlled trial examined the effects of family-based interpersonal psychotherapy (FB-IPT) on non-suicidal self-injury (NSSI), depressive symptoms, and family cohesion in adolescents.

METHOD: A multidisciplinary team delivered care; two IPT-trained psychiatric nurses provided psychoeducation and safety/adherence monitoring in a non-therapist role. Forty-eight adolescents were randomized to FB-IPT or treatment as usual (TAU) for 12 weeks. Outcomes (Ottawa Self-Injury Inventory, Hamilton Depression Scale, Family Environment Scale-Chinese Version) were assessed at baseline, post-treatment, and 3-month follow up.

RESULTS: The FB-IPT group showed significantly greater reductions in NSSI and depressive symptoms, and increased family intimacy, compared to the TAU group.

CONCLUSION: FB-IPT may be an effective adjunctive treatment for adolescents engaging in NSSI.
