Clinical Report: Development and validation of machine learning models for PP-PTSD

Overview

This study developed and validated machine learning models to identify factors influencing postpartum post-traumatic stress disorder (PP-PTSD) in first-time mothers. The Gradient Boosting model demonstrated high predictive accuracy, with key predictors identified as depression and social support.

Background

Postpartum post-traumatic stress disorder (PP-PTSD) affects a significant number of first-time mothers, with an incidence of 25.18% observed in this study.

Data Highlights

Key Findings

• The incidence of PP-PTSD among participants was 25.18%.
• Key predictors identified included social support, depression, neonatal caregiving style, husband’s participation, and sleep quality.
• Depression and poor sleep quality were associated with an increased risk of PP-PTSD.
• Higher social support and greater husband’s participation were linked to a reduced risk of PP-PTSD.
• The Gradient Boosting model outperformed other models, including Logistic Regression, in predictive accuracy.
• SHAP analysis indicated that social support, husband’s participation, sleep quality, and depression were major contributors to model predictions.

Clinical Implications

The findings suggest that addressing factors such as depression and enhancing social support may be critical in mitigating the risk of PP-PTSD in first-time mothers. The validated Gradient Boosting model could serve as a tool for risk stratification and targeted interventions.

Conclusion

This study provides a framework for understanding and predicting PP-PTSD in primiparous women.
