Efficacy of in-person versus digital mental health interventions for postpartum depression: meta-analysis of randomized controlled trials

ABSTRACT

Aim

This meta-analysis aimed to compare the efficacy of in-person and digital mental health interventions in addressing Postpartum Depression.

Methods

Following PRISMA guidelines, the protocol for this meta-analysis was registered at the Open Science Framework (Retrieved from osf.io/wy3s4). This meta analysis included Randomized Controlled Trials (RCTs) conducted between 2013 and 2023. A comprehensive literature search identified 35 eligible RCTs from various electronic databases. Inclusion criteria focused on pregnant women over 18 years old, encompassing antenatal depression and up to two years postpartum. Diagnostic interviews or Edinburgh Postnatal Depression Scale (EPDS) were used to establish PPD. Digital interventions included telephonic, app-based, or internet-based approaches, while in-person interventions involved face-to-face sessions.

Results

The meta-analysis revealed a moderate overall effect size of −0.69, indicating that psychological interventions are effective for PPD. Digital interventions (g = −0.86) exhibited a higher mean effect size than in-person interventions (g = −0.55). Both types of interventions displayed substantial heterogeneity (digital: I² = 99%, in-person: I² = 92%), suggesting variability in intervention content, delivery methods, and participant characteristics.

Conclusion

Digital mental health interventions show promise in addressing PPD symptoms, with a potentially greater effect size compared to in-person interventions. However, the high heterogeneity observed in both modalities underscores the need for further research to identify key drivers of success and tailor interventions to diverse populations. Additionally, the choice between digital and in-person interventions should consider individual needs and preferences. Ongoing research should further investigate and optimise intervention modalities to better serve pregnant women at risk of PPD.
