Brief Summary

  • Basic premise: Depression often follows changes in one’s interpersonal environment (e.g., struggle with a significant other, loss of a loved one). Once depressed, symptoms can lead to compromised interpersonal functioning, which can precipitate continued stressful events. The goal in therapy is to address both the stressful life events and improved social support.
  • Essence of therapy: IPT focuses on improving problematic interpersonal relationships or circumstances that are directly related to the current depressive episode.
  • Length: Acute IPT for major depression is typically delivered over 12-16 sessions, although courses as short as 3-8 sessions have demonstrated efficacy. Maintenance IPT has been tested in weekly, biweekly, and monthly doses over as long as three years. A briefer, more structured version of IPT, Interpersonal Counseling (IPC), is designed for use primarily in non-mental health settings, such as primary care clinics. IPC is typically delivered in 3-8 sessions.


Note: Interpersonal psychotherapy was developed by Klerman and Weissman for depression and has been expanded for other disorders. A brief history of interpersonal psychotherapy (Weissman, 2006) describes the development of IPT. If you are interested in joining the international IPT organization, contact the IPT Google group.
