The aim of this study was to investigate the diagnostic value of a stress coping scale for predicting perceived psychological traumatic childbirth in mothers.

This cross-sectional study was performed on 400 new mothers (within 48 hours of childbirth). Psychological traumatic childbirth was evaluated using the 4 diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders. Coping was measured using Moss and Billings’ Stress Coping Strategies Scale.

The overall mean score of stress coping was 29 ± 14.2. There were 193 (43.8%) mothers that had experienced a psychological traumatic childbirth. A stress coping score ≤ 30, with a sensitivity of 90.16 (95% CI = 85.1–94.0), and a specificity of 87.44 (95% CI = 82.1–91.6), was determined as a predictor of psychological traumatic childbirth. So that among mothers with stress coping scores ≤ 30, 87% had experienced a psychological traumatic childbirth.

Investigating the degree of coping with stress can be used as an accurate diagnostic tool for psychological traumatic childbirth. It is recommended that during pregnancy, problem-solving and stress management training programs be used as psychological interventions for mothers with low levels of stress control. This will ensure that they can better cope with traumatic childbirth and post-traumatic stress in the postpartum stage.
