Collaborative decision making improves interpersonal psychotherapy efficiency: A randomized clinical trial with postpartum women

•This randomized clinical trial with 140 postpartum outpatients meeting criteria for DSM-IV major depression demonstrated that a clinician-managed version of interpersonal psychotherapy (CM-IPT) demonstrated similar outcomes as standard IPT and was superior to waitlist control.•CM-IPT – which allows patient and therapist to negotiate when to schedule sessions rather than following the standard weekly format – may be a more efficient and less expensive option for treating acute depression than mandated weekly IPT.•Permitting clinicians and patients to use their judgment is likely to be a more efficient and effective way to implement evidence-based psychotherapy in the community.
