Change in depression: PHQ-2 scores between 0 and 3 indicate a major depressive disorder is unlikely and PHQ-2 scores between 3 and 6 indicate a major depressive disorder is likely. The average scores at baseline for participants with complete data (gray line) and incomplete data (orange and blue lines) indicate that all groups were likely to have a major depressive disorder. Upon completion of 1 assessment after 30 days, all groups observed a decline in PHQ-2 scores and were unlikely to have depression. PHQ-2: Patient Health Questionnaire 2-Item Scale.
