Participant Flow

Participants were recruited beginning August 20, 2012. Enrollment sites included Hartford Hospital (Hartford, CT) and Baystate Medical Center (Springfield, MA).

154 participants gave written consent for study participation and 137 were randomized. Therefore, 17 participants were excluded for the following reasons: no show after screen (10), high PHQ9 (2), moved out of area (2), current drug use (1), advanced gestational age (1), and stress too high to continue (1).
