A systematic review of interpersonal psychotherapy for postpartum depression

Background: The current study endeavored to systematically integrate and quantitatively evaluate the effec-tiveness of interpersonal psychological interventions for postpartum depression patients.Methods: Four electronic databases Pubmed, Embase, Cochrane and Web of Science were employed for literature retrieval, and the search time was from the inception of the database to May 30, 2022. Literature screening and data extraction were performed independently by two researchers.Results: A total of 528 studies were screened, and 9 of them were finally included. There were 1012 subjects, 518 of them were assigned in experimental group and 494 in control. Evidence from interpersonal psychological interventions indicated that the data on postpartum depression, satisfaction with family, and social support in both groups after intervention included: depression score [MD =-2.80, 95%CI (-3.86 to-1.74), P < 0.051, satisfaction score [MD = 8.41, 95%CI (1.49 to-15.33), P < 0.051, and social support score [MD = 1.83, 95%CI (-2.10 to-5.76)1 of postpartum depression patients. P values < 0.05 indicated substantial improvement as compared to control.Limitations: During the research process, it is impossible for the experimental group and the researchers to use double-blind trials simultaneously, which may present a Hawthorne effect, but this can be avoided by general psychological intervention for the control. Conclusions: Interpersonal psychotherapy could improve depression in patients with postpartum depression, but the appropriate intervention time was between 4 and 8 weeks, and it also improved satisfaction with family of patients, and the longer the intervention, the higher the satisfaction with the family.
