 The investigators are proposing a study that will specifically and innovatively focus on the development of a novel positive psychology intervention that is adapted for patients with T2D. The MGH Diabetes Center and MGH primary care clinics will serve as the source of subjects for the study, with patients who have a diagnosis of T2D serving as potential subjects. The investigators will enroll 12 T2D patients, who will take part in an 16-week PP-MI health behavior intervention.
