This study investigates the factor structure and reliability of the Edinburgh Postnatal Depression Scale (EPDS) across multiple time points in perinatal women in China.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 849 perinatal women participated in this study, with data collected at six time points: early, mid, and late pregnancy, as well as 1, 3, and 6\u202fmonths postpartum. Parallel analysis and exploratory factor analysis were conducted to determine the factor structure of the EPDS. Internal consistency was assessed using Cronbach\u2019s alpha. Multigroup confirmatory factor analysis was performed to assess measurement invariance between the antepartum (T1\u2013T3) and postpartum (T4\u2013T6) groups, and to assess the fit of model across the perinatal period.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three-factor models fit best for the EPDS during the perinatal period when analyzed at each time points and across the perinatal period.
