In this randomized clinical trial, the Treatment Initiation and Participation Program participants were 3 times more likely to be at least 80% adherent to their antidepressant pharmacotherapy at both 6 and 12 weeks. The Treatment Initiation and Participation Program did not have a sustained effect on depression; however, participants who reported 80% adherence at both 6 and 12 weeks showed greater improvement in depression severity by 24 weeks.
