This study aims to assess anxiety during the perinatal period, assessing participants during pregnancy and the postpartum period. At each time point, participants complete a structured clinical interview over current anxiety and mood symptoms as well as an online questionnaire. Online questionnaires assess sociodemographic, obstetric/medical, and psychological risk factors. This study will help us to better understand who is the most at risk to develop or experience worsening of anxiety during the perinatal period.
