This study will classify patients seen in the Depression Clinic of the UCSF Department of Psychiatry and Behavioral Sciences into one of five phenotypes (subtypes), including: 1) Anhedonia, 2) Cognitive deficits, 3) Stress sensitivity, 4) Anxious distress, and 5) Grief.
After phenotyping, participants will be randomized to receive phenotype-specific intervention (PSI) or care as usual (CAU).
