New moms can be at risk for perinatal depression (PND). The New Moms Mood Tracking and Wellbeing study is investigating mood changes, risk factors for depression and anxiety and treatment response around the time of delivery. Participants will be asked to complete three sets of online surveys between week 28 gestation and week 20 after delivery, in addition to downloading an app to collect data using their smartphone sensors and brief symptom surveys every other week. Women with elevated symptoms can participate in treatment. Women will be randomized to one of two conditions - Perinatal Psychiatric Care or Screening and Treatment for Anxiety and Depression (STAND). In Perinatal Psychiatric Care, participants will receive appointments with psychiatry clinicians. In STAND, participants will be further allocated to Online therapy with Coaching or Clinical Care, which includes both psychotherapy and psychiatry appointments. Treatment can last up to 6 months and there will be treatment related assessments for the duration of the 6 months, in addition to brief symptom surveys on a regular basis. Therefore, participation can last between 24 and 52 weeks, as both time of delivery and treatment enrollment timepoint cannot be scheduled in advance.
