Exploration of a cognitive model to predict post-traumatic stress symptoms following childbirth

Abstract

Women can suffer from post-traumatic stress disorder (PTSD) following childbirth. This study investigated the application of a cognitive model to PTS symptoms following childbirth and explored the addition of social support to the model. Methods Women ( N = 138) completed questionnaires in pregnancy, 3-weeks and 3-months after birth, measuring prior trauma, beliefs, and coping in pregnancy; and birth interventions, social support, post-traumatic cognitions, and PTS symptoms post-birth. Results Using structural equation modeling, a cognitive model explained 23% of the variance in PTS symptoms 3-weeks postpartum. Three-months postpartum, the model explained only 9% of the variance in PTS symptoms. The addition of social support, partially mediated by post-traumatic cognitions, increased the variance to 16%. Discussion Results suggest that a cognitive model accounts for early PTS symptoms after birth. Social support after birth increases the explanatory power of the model at 3 months. A test of the model on a larger sample is warranted.
