Study design and participants
The PSYCHE study was a single-centre repeated cross-sectional study within a prospective cohort of women who gave birth at a French level 3 maternity unit.
Women who gave birth at or after 22 weeks of gestation in our hospital, were affiliated with a French health insurance fund, and consented to participate were eligible for this study. Women younger than 18 years, those who did not speak French, and those who refused to participate were excluded.
