Prevalence of Psychiatric Disorders During Pregnancy at 2nd Trimester Ultrasound: a Feasibility Study in the General Population

To determine the prevalence of the presence of at least one characterized psychiatric disorder, in remission or not, during pregnancy, at the time of the second-trimester ultrasound (T2 ultrasound) based on a standardized clinical assessment.

Young women represent a population at risk of psychiatric disorders, the first signs of which
 often appear between the ages of 15 and 25. Psychiatric disorders are a major source of
 disability and healthcare costs.
 
 The perinatal period is an additional period of psychological vulnerability, during which
 women are at increased risk of developing or worsening psychiatric disorders. Unfortunately,
 psychiatric disorders seem to be largely under-diagnosed during this period, and therefore
 under-treated.
 
 The goal of this Prospective multicenter study is to determine the prevalence of the presence
 of at least one characterized psychiatric disorder, as defined by the use of the Mini
 International Neuropsychiatric Interview (MINI), in remission or not, during pregnancy, at
 the time of the second-trimester ultrasound (T2 ultrasound) based on a standardized clinical
 assessment.
 
 Participants will complete self-questionnaires and have a standardized psychiatric evaluation
 at T2 ultrasound and at 2 months postpartum.
