This study will compare two psychological treatments for major depressive disorder (MDD): cognitive-behavioral therapy (CBT) and acceptance and commitment therapy (ACT). Both treatments are well-studied and supported by evidence as effective options for people experiencing depression. These treatments will be delivered in an online group format via Zoom. The study will enroll up to 100 participants with depression. Half of the participants will receive online group CBT and half will receive online group ACT. There will be up to 10 members in each group. For both conditions, treatment will be provided over 8 weeks, with a 6-month follow-up period. Enrollment will be ongoing and groups will occur simultaneously. Potential participants are asked to complete an initial screening and an intake evaluation to determine eligibility. They will then receive 8-weeks of treatment. Participants will complete self-report questionnaires throughout their time in the study.
