Methods Using data from a collaborative care intervention trial for post-CABG depression, we conducted exploratory post hoc analyses of 284 depressed post-CABG patients (2-week posthospitalization score in the 9-item Patient Health Questionnaire ≥10) and 146 controls without depression who completed the Life Orientation Test – Revised (full scale and subscale) to assess dispositional optimism. We classified patients as optimists and pessimists based on the sample-specific Life Orientation Test – Revised distributions in each cohort (full sample, depressed, nondepressed). For 8 months, we assessed health-related quality of life (using the 36-item Short-Form Health Survey) and mood symptoms (using the Hamilton Rating Scale for Depression [HRS-D]) and adjudicated all-cause rehospitalization. We defined treatment response as a 50% or higher decline in HRS-D score from baseline.
