Objectives: We aimed to validate Web-based questionnaires for the common pregnancy complications gestational diabetes, gestational hypertension, and preeclampsia.
Study Design And Setting: We included 1,809 women participating in the PRegnancy and Infant DEvelopment (PRIDE) Study who delivered in 2012-2017, for whom relevant data were complete. Sensitivity, specificity, and positive and negative predictive values of self-reported diagnoses of gestational diabetes, gestational hypertension, and preeclampsia were determined using obstetric records as reference standard.
