Patients with type 2 diabetes often struggle to develop healthy routines for themselves and meet their treatment goals. This study aimed to compare the positive effects of two diabetes self-care strategies on psychosocial outcomes and glycemic control at the one-year follow-up point. Seventy patients with type 2 diabetes were randomly assigned to one of three groups: a control group (C.G.) that received no intervention, a group receiving a training course after six months (GCR), and a third group (T.S.L.) that was responsible for receiving monthly phone calls to promote self-care behaviours and try to detect and solve problems (C.G., GCR, T.S.L.). Multiple surveys and lab tests were administered at the beginning and end of the study
