A nomogram for predicting postpartum post-traumatic stress disorder: a prospective cohort study.

Area of Science:

• Obstetrics and Gynecology
• Psychiatry
• Public Health

Background:

• Postpartum post-traumatic stress disorder (PTSD) is a significant psychological stress disorder with long-term consequences.
• Postpartum PTSD receives less attention in China compared to other postpartum psychiatric disorders.
• Early identification and intervention are crucial for managing postpartum PTSD.

Purpose of the Study:

• To investigate the risk factors associated with postpartum PTSD.
• To develop a convenient and rapid nomogram screening tool for identifying high-risk pregnant women.
• To aid clinical staff in timely preventative and management measures for postpartum PTSD.

Main Methods:

• A questionnaire survey was conducted with 602 pregnant women hospitalized for delivery.
• Logistic regression analysis identified independent risk factors and protective factors for postpartum PTSD.
• A nomogram prediction model was developed and validated internally and externally using statistical methods.

Main Results:

• The incidence of postpartum PTSD was 11.1%.
• Independent risk factors included poor sleep self-assessment, cesarean section, instrumental delivery, and fear of labor.
• A high Quality of Relationship Index score was a protective factor.
• The nomogram model demonstrated high accuracy (AUC 0.928 in training, 0.907 in validation) and clinical utility.

Conclusions:

• The developed nomogram model effectively predicts postpartum PTSD risk.
• Early identification of high-risk pregnant women is possible through this screening tool.
• Timely preventive interventions can be implemented based on the nomogram's predictions.
