Evaluation of the effect of a nurse navigation program developed for postpartum mothers on maternal health: A randomized controlled study

Proactive approaches to preventing postpartum depression in non-depressive pregnant women: a comprehensive scoping review

Introduction

Postpartum depression is a significant global health challenge that affects mothers, infants, and families. Although various preventive strategies show promise, comprehensive reviews evaluating interventions among pregnant women without a clinical diagnosis of depression remain limited. This scoping review aims to identify and synthesize the existing evidence on proactive postpartum depression prevention programs initiated during pregnancy.

Methods

Following PRISMA guidelines for scoping reviews, we systematically searched PubMed and Scopus, supplemented by manual reference reviews. Our search strategy combined terms related to postpartum depression, pregnancy, and preventive interventions. Studies were included if they evaluated interventions conducted during pregnancy, targeting women without a clinical diagnosis of depression, and assessed PPD outcomes using established diagnostic criteria or validated screening tools. Only English-language articles published between 2013 and 2023 were considered.

Results

A total of 49 studies met the inclusion criteria. Interventions were categorized into nine themes: psychoeducation (n = 18), home visits (n = 6), cognitive behavioral therapy (CBT) (n = 6), mindfulness (n = 6), exercise (n = 4), dietary supplements (n = 3), interpersonal therapy (IPT) (n = 4), consultation (n = 1), and inhalation aromatherapy (n = 1). Psychoeducational and mindfulness-based interventions consistently reduce PPD risk, particularly when delivered in structured, theory-driven formats and incorporating family support. Digital CBT interventions demonstrated limited effectiveness due to lower engagement, while home-visit and consultation-based interventions were effective when integrated into existing maternal healthcare despite scalability challenges. Exercise and dietary supplement interventions yielded inconsistent outcomes, indicating that factors such as adherence, duration, and intensity are crucial determinants of effectiveness.

Conclusion

Various proactive interventions are available to prevent PPD, and this scoping review systematically maps the different strategies used and their outcomes. Proactive, theory-based, and multi-component interventions, particularly psychoeducational and mindfulness programs, demonstrate promising potential. Future research should emphasize evaluating long-term outcomes, optimizing digital engagement strategies, and developing culturally tailored models to enhance scalability and accessibility across diverse populations, including low-resource settings.

The effectiveness of mental health interventions involving non-specialists and digital technology in low-and middle-income countries - a systematic review

BACKGROUND

Combining non-specialists and digital technologies in mental health interventions could decrease the mental healthcare gap in resource scarce countries. This systematic review examined different combinations of non-specialists and digital technologies in mental health interventions and their effectiveness in reducing the mental healthcare gap in low-and middle-income countries.

METHODS

Literature searches were conducted in four databases (September 2023), three trial registries (January-February 2022), and using forward and backward citation searches (May-June 2022). The review included primary studies on mental health interventions combining non-specialists and digital technologies in low-and middle-income countries. The outcomes were: (1) the mental health of intervention receivers and (2) the competencies of non-specialists to deliver mental health interventions. Data were expressed as standardised effect sizes (Cohen's d) and narratively synthesised. Risk of bias assessment was conducted using the Cochrane risk-of-bias tools for individual and cluster randomised and non-randomised controlled trials.

RESULTS

Of the 28 included studies (n = 32 interventions), digital technology was mainly used in non-specialist primary-delivery treatment models for common mental disorders or subthreshold symptoms. The competencies of non-specialists were improved with digital training (d ≤ 0.8 in 4/7 outcomes, n = 4 studies, 398 participants). The mental health of receivers improved through non-specialist-delivered interventions, in which digital technologies were used to support the delivery of the intervention (d > 0.8 in 24/40 outcomes, n = 11, 2469) or to supervise the non-specialists' work (d = 0.2-0.8 in 10/17 outcomes, n = 3, 3096). Additionally, the mental health of service receivers improved through digitally delivered mental health services with non-specialist involvement (d = 0.2-0.8 in 12/27 outcomes, n = 8, 2335). However, the overall certainty of the evidence was poor.

CONCLUSION

Incorporating digital technologies into non-specialist mental health interventions tended to enhance non-specialists' competencies and knowledge in intervention delivery, and had a positive influence on the severity of mental health problems, mental healthcare utilization, and psychosocial functioning outcomes of service recipients, primarily within primary-deliverer care models. More robust evidence is needed to compare the magnitude of effectiveness and identify the clinical relevance of specific digital functions. Future studies should also explore long-term and potential adverse effects and interventions targeting men and marginalised communities.
