Participation in this single-blind study will last about 9 months and will include 22 study visits. There will be four pretreatment visits, during which participants will undergo a variety of tests and procedures, including interviews and questionnaires about depression and anxiety; tests on memory, attention, reaction time, and reading; and an MRI scan. Following completion of the initial assessments, participants will be randomly assigned to receive CBT or supportive psychotherapy. Participants in both groups will attend eighteen 1-hour treatment sessions over 5 months. Participants attending CBT sessions will learn specific thought processing and behavioral exercises to help reduce depressive symptoms. Participants attending psychosocial therapy sessions will learn about signs and symptoms related to depression and will be provided support in coping with their depression.
