During the perinatal period, women are at an increased risk for the onset/exacerbation of obsessive-compulsive disorder (OCD) and may experience perinatal-specific obsessions and/or compulsions. Past research has provided preliminary findings regarding the prevalence of OCD in the perinatal period but has often reported limited metrics and ignored perinatal specific symptoms. This research aimed to assess the prevalence and incidence of maternal OCD between the third trimester in pregnancy and 6 months postpartum. An unselected sample of 763 English-speaking pregnant women and new mothers participated in a longitudinal, province-wide study between their third trimester in pregnancy and 9 months postpartum. They completed 3 online questionnaires and interviews (data collected between February 9, 2014, and February 14, 2017) and were administered a diagnostic interview to determine OCD status based on diagnostic criteria. A weighted prenatal period prevalence of 7.8% and a postpartum period prevalence of 16.9% were found. The average, prenatal, point prevalence estimate was 2.9%, and the average, postpartum, point prevalence estimate was 7.0%. Point prevalence gradually increased over the course of pregnancy and the early postpartum, attaining a peak of close to 9% at approximately 8 weeks postpartum, with a gradual decline thereafter. The cumulative incidence of new OCD diagnoses was estimated at 9% by 6 months postpartum. Our study suggests that when women are encouraged to report their perinatal-specific symptoms, and current diagnostic criteria are applied, estimates for perinatal OCD may be higher than previously believed.
