The authors sought to understand patient experiences with group teletherapy to inform improvements in service delivery. From December 2022 to October 2023, semistructured interviews were conducted with 20 adults with depression or bipolar disorder who had received outpatient group teletherapy in the past 2 years. A rapid thematic analysis was conducted by using a matrix to identify patterns and synthesize data. A logic model from the patients' perspective was developed by extracting common themes related to elements of effective group teletherapy. Telehealth allowed for more empowered engagement in group teletherapy and enabled better access and longitudinal attendance for many patients, compared with in-person group therapy. However, many patients reported a reduced sense of emotional intimacy and connectedness with telehealth, and some reported that technology challenges and distractions contributed to feelings of disconnection. Patients were divided in their modality preferences, but many expressed an interest in receiving at least some of their group therapy sessions by telehealth. Although group teletherapy has the potential to meet patients' needs and preferences, more work is needed to improve the quality of the experience for patients.
