Couple-based interpersonal psychotherapy for first-time parents: A process evaluation

Abstract

Purpose: First-time parents have an increased risk of depression during the transition to parenthood, which has long-term adverse effect on the infant development. Interpersonal psychotherapy (IPT) has been shown to effectively reduce postnatal depression. The objectives of this study were to explore first-time parents' perceptions of a couple-based IPT program and to identify positive and negative influences on the effectiveness of the intervention through a process evaluation.

Design and methods: A process evaluation was conducted as part of a randomized controlled trial of a couple-based IPT program. A program satisfaction questionnaire was used to assess the participants' satisfaction with the structure, process and outcome of the program. Semi-structured telephone interviews were conducted with a purposive sample of 44 first-time parents who had received the couple-based IPT. The interview data were analyzed by thematic analysis.

Results: The qualitative findings showed that the parents perceived couple-based IPT as useful for enhancing their interpersonal relationship, emotional control and competence in child care. The successful implementation of the couple-based IPT program was influenced by its delivery by midwives, the interactive lessons used to engage the participants, the close fit of the teaching contents to the needs of first-time parents and the flexible program schedule and delivery mode.

Conclusions: The process evaluation indicates that couple-based IPT is an acceptable and feasible intervention for first-time parents to facilitate a healthy transition to parenthood.

Practice implications: The couple-based IPT can be used as an adjunct to standard care to promote perinatal health.
