To inform future wellness implementation, in-depth, semi-structured interviews are conducted with patients who participated in wellness groups ("participants"), and with patients who were referred (because they were overweight or obese) but did not participate ("non-participants"). Participants consist of all enrolled patients who attended the wellness program with special attention to those patients who completed at least half of the wellness program. Non-participants consist of patients who were referred to the wellness program but did not attend. Clinicians were interviewed specifically regarding wellness implementation.
