Fig. 1. Decline in average PHQ-9 scores at each session by race. AA=African American; PHQ-9=9-item Patient Health Questionnaire. PHQ-9 scores were self-entered at the beginning of each CCBT session. Changes in depression and anxiety symptom outcomes were assessed using linear mixed models controlling for age, gender, education, baseline symptom and baseline pharmacotherapy use. We first evaluated whether the change in symptom outcome across the eight sessions differentiated by race (i.e. session-by-race interaction). Where interaction effects were non-significant, they were removed from the model and only the main effect reported.
