Objective/methods: The authors examined recurrence rates of major depression in elderly subjects with different foci of interpersonal psychotherapy (IPT), who were treated for up to 3 years with either monthly maintenance IPT and pill placebo or with monthly clinical management and pill placebo.
Results: Among subjects with an IPT focus on role conflict, a greater proportion of those treated with maintenance-IPT survived for 3 years without recurrence than those treated with placebo/clinical management. Median time to recurrence was 68.9 weeks in IPT-treated patients versus 16.3 weeks for patients in clinical management. Subjects with an IPT focus on abnormal grief or role transition demonstrated no effect differential for maintenance IPT and pill-placebo on recurrence prevention over supportive clinical management and pill-placebo.
Conclusion: If replicated in a larger sample, these findings have important implications for ongoing case-management decisions.
