Does interpersonal psychotherapy protect women from depression in the face of stressful life events?
The present study compared the role of life events in predicting time to index episode onset under conditions of no or variable treatment versus the role of life events in predicting time to recurrence during maintenance interpersonal psychotherapy (IPT). Eighty-three women with recurrent major depression participated in acute IPT treatment followed by 2 years of maintenance IPT. Life events were assessed using contextual interview and rating methods. Cox regression survival analyses indicated that, although severe life events were significantly associated with time to index episode onset, there was little evidence of an association between events experienced during maintenance treatment and time to recurrence. These results provide evidence that IPT may decrease the potency of life events in provoking recurrence.
