Trajectories of long-term outcomes for postnatally depressed mothers treated with group interpersonal psychotherapy

Archives of Women's Mental Health, 05/03/2012

Group interpersonal psychotherapy participants were significantly less likely to require follow–up treatment. Limitations include the use of self–report questionnaires to classify recovery. The positive finding that fewer women in the group condition experienced a persistent course of depression highlights its possible enduring effects after treatment discontinuation.


  • Approximately 2 years posttreatment, all women in the original RCT (N = 50) were invited to participate in a mailed follow-up.
  • A repeated measures analysis of variance assessed differences between the treatment and control conditions on depression and interpersonal scores across five measurement occasions: baseline, mid-treatment, end of treatment and 3-month and 2-year follow-up.
  • Chi-square tests were used to analyse the percentage of participants in the four recovery categories.


  • Mothers who received IPT-G improved more rapidly in the short-term and were less likely to develop persistent depressive symptoms in the long-term.
  • Fifty seven percent of IPT-G mothers maintained their recovery over the follow-up period.
  • Overall, IPT-G participants were significantly less likely to require follow-up treatment.
  • Limitations include the use of self-report questionnaires to classify recovery.
