This study seeks to determine the feasibility and efficacy of a Problem Solving Therapy intervention for the treatment of late life depression (LLD). Participants diagnosed with LLD will participate in six sessions of Problem Solving Therapy, a form of talk-therapy, over a period of eight weeks. A Case Manager (CM) will lead the PST. The primary outcome measure is depression severity and will be measured throughout the study at weeks 0, 4, and 8. the secondary outcome measure is quality of life and will be measured at week 0 (pre-intervention) and week 12.
