RECRUITMENT
We enrolled participants from February 1, 2018, to June 30, 2019. Where possible, recruitment procedures harnessed existing screening activities at each recruitment site. In the prenatal clinic, front desk staff conducted screenings at all prenatal visits; in pediatrics, practice assistants completed screenings at all well-child visits. The postpartum unit was added as a recruitment venue 3 months into the enrollment period to address an initial slow rate of study enrollment; because depression screening was not routinely performed in that setting, research staff directly performed the screenings. Clinicians were alerted to all positive screens. Patients were informed directly of their result and option to participate in the study. Among interested patients, research staff assessed eligibility and obtained informed consent.
