Coaching as an Adjunct to Ketamine Therapy for Treatment-Resistant Depression

Participation in the study will involve adding coaching sessions to existing ketamine maintenance treatment for patients receiving ongoing maintenance IV ketamine or IN esketamine treatment at MGH's Ketamine Clinic. If participants are eligible, they will be invited to participate in 12 weekly, 50-minute one-on-one coaching sessions conducted via Zoom. These sessions are designed to help participants process and integrate their experiences with ketamine treatment, to support personal growth and symptom improvement. The coaching is non-clinical, collaborative, and participant-directed, and is provided by trained psychedelic integration coaches from the Fireside Project. Throughout the 3-month coaching period and again at a 1-month follow-up, participants will complete monthly study visits that include brief remote assessments with a study clinician, along with additional self-report questionnaires. These visits will take approximately 1 to 2 hours, depending on the time point.
