A Couple-based Interpersonal Psychotherapy on Postnatal Depression and Family Sense of Coherence: a Randomized Controlled Trial

Brief Summary

Detailed Description

Background: Postnatal depression is a common public health problem which has long-term sequelae on the family and the infant's psychosocial development. Interpersonal psychotherapy has demonstrated its value as one of the most effective interventions for postnatal depression. Enhancement of family sense of coherence may be helpful for women who are at risk for postnatal depression. However, few studies in the context of Chinese parenthood have evaluated the effect of interpersonal psychotherapy on postnatal depression and the underlying mechanisms. Aim: To examine the effect of a couple-based interpersonal psychotherapy for first-time Chinese mothers and fathers on depressive symptoms (primary outcome), family sense of coherence (secondary outcome), and marital relationships (secondary outcome) immediately after intervention and at 6 weeks and 6 months postpartum. Method: A randomized controlled trial will be used to evaluate the effect of a couple-based interpersonal psychotherapy on depressive symptoms (primary outcome), family sense of coherence (secondary outcome), and marital relationships (secondary outcome) immediately after intervention and at 6 weeks and 6 months postpartum. A convenience sample of 125 couples will be recruited at the antenatal clinics and randomly assigned to either experimental or control group. The experimental group will receive the intervention in addition to the standard perinatal care, while the control group will only receive the standard perinatal care. Intervention: The intervention consists of three weekly 2-hour antenatal sessions using an interpersonal psychotherapy approach that focused on enhancement of family sense of coherence and two telephone follow-ups within the first four weeks after delivery. Outcome measures: The primary outcome measure of postnatal depression will be assessed by the Edinburgh Postnatal Depression Scale. Secondary outcome measures of family sense of coherence and the marital relationship, will be assessed by the Family Sense of Coherence Scale and Dyadic Adjustment, respectively, at baseline, immediately post-intervention, 6 weeks and 6 months postpartum. Data analysis: Linear mixed models will be used to test for significant differences between the groups on outcome variables.
