Treatments for Improving Mood in Depressed Teens-3

In Phase 3, Study A, the investigators will conduct a pilot Randomized Control Trial (RCT) of 12 weeks of hatha yoga vs. 12 weeks of group CBT. Participants will be adolescents with depression. Parents will also be invited to participate in assessments regarding their child. Study B, which will run concurrent to Phase 3, will be for participants who did not meet the depression inclusion criteria or had recent changes in therapy or medications that make them ineligible for Phase 3. Their data will not be analyzed. They are recruited only for group participation. Participants will be randomized to Phase 3 groups of 12 weeks of hatha yoga or group CBT. Parents will also be invited to participate in assessments regarding their child. * Due to social distancing requirements related to COVID‐19, all interventions have been delivered remotely via video‐based platforms as of late March 2020.
