Psychosocial Support Interventions After Perinatal Loss: A Network Meta-Analysis of RCTs Indicates What Works Best...

Psychosocial interventions are recognized as effective nonpharmacological treatments that can enhance the mental well-being of women dealing with perinatal loss. However, as these interventions vary widely, there is currently no review that systematically evaluates and ranks their effects on the mental health of women affected by perinatal loss.

The aim of this study is to integrate the existing evidence, assess and compare the effects of psychosocial interventions on negative emotions among women experiencing perinatal loss, rank the effect sizes of various interventions, and identify the most effective intervention on the basis of different outcome measures.

Seven English-language databases were systematically searched for randomized controlled trials (RCTs) focusing on women experiencing perinatal loss, with publications up to August 20, 2024. Traditional pairwise meta-analyses were performed using Review Manager 5.4.1, while Stata 18.0 was employed for network meta-analysis and evidence synthesis. The surface under the cumulative ranking curve (SUCRA) was used to assess the efficacy of the interventions. The protocol was registered with PROSPERO under number CRD42024530312.

A total of 30 RCTs encompassing 6181 participants were included in the analysis. On the basis of the SUCRA rankings, problem-solving therapy was identified as an effective treatment for alleviating depression and anxiety among women experiencing perinatal loss (depression: SUCRA = 82.55%, SMD = -1.34, 95% CI [-2.41, -0.27]; anxiety: SUCRA = 97.7%, SMD = -2.83, 95% CI [-4.26, -1.40]). Additionally, bereavement intervention emerged as the most effective approach for improving grief symptoms (SUCRA = 81.60%, SMD = -1.11, 95% CI [-2.14, -0.09]).

Compared with traditional treatment, psychosocial intervention can improve the psychological state of women with perinatal loss, and the differences in the effects of face-to-face and technology-assisted interventions should be further explored. Moreover, problem-solving therapy has proven to be effective and appears to be the most effective method for alleviating depressive and anxiety symptoms among women experiencing perinatal loss, while bereavement support is the most effective method for grief due to perinatal loss. Nursing and health policymakers can develop various intervention strategies according to the varied psychological states of women experiencing perinatal loss.
