Randomized controlled trial; adults with type 2 diabetes ()
Three-month lifestyle (diet and PA) self-management program (brief tailored) plus follow-up phone calls for one year
Diabetes self-management, self-efficacy for physical activity, and barriers to diabetes self-care were evaluated at baseline, postintervention, and after follow-up
Randomized controlled trial; postmenopausal type 2 diabetic women ()
Mediterranean lifestyle program (6-month intervention to construct group coach and 12- and 24-month follow-up); videotapes also used for home-based practice (one hour per day)
Lifestyle behaviors (i.e., physical activity and stress management) and psychosocial variables (e.g., social support, problem solving, self-efficacy, depression, and quality of life), at baseline and 6, 12, and 24 months
↑ Quality of life (stress management, healthy diet, exercise), psychosocial factors (self-efficacy, problem solving, supportive resources), after 12 and 24 months of problem-solving
Quasiexperiment secondary analysis of data collected from RCT; overweight adult () with heart disease and diabetes
Healthy eating and exercise lifestyle program (group-based supervised structured exercise sessions, 4 months) plus telephone follow-up calls (4 months)
Exercise, self-efficacy for weight loss, and depressive symptoms were measured at baseline, postactive phase (4 months), and postmaintenance phase (12 months)
↑ Exercise adherence and weight loss; male gender, self-efficacy, time, and depressive symptoms are independent predictors for exercise duration
Quasiexperiment; dyadic data from 117 married couples in which one partner was diagnosed with type 2 diabetes
—
Survey of two exercise items (diabetes self-care activities); seven-item self-efficacy subscale of the multidimensional diabetes questionnaire
Health stress of patients in the form of higher comorbidities number and specific stress of diabetes in both patient and spouse ↔ ↓ patient adherence to exercise ↔ diabetes self-efficacy and depressive symptoms
Randomized pilot clinical trial; type 2 diabetic patients ()
Four sessions of clinician-led, patient-centered group education targeting type 2 diabetes self-management (medications, exercise, diet, home monitoring, etc.) for 3 months
HbA1c, self-efficacy scale, and specific knowledge and understanding scale at baseline, postintervention, and at the 1-year follow-up
↑ Glycemic control, self-management, and effect of time-by-treatment interaction might partially be mediated via the development of self-efficacy
Randomized clinical trial; adults with type 2 diabetes ()
Individualized education (IE, 3 sessions of 1-hour individual education once a month), or group education (GE, sessions of 2-hour group education) or control (UC) for 1 year plus 6.8 months and 12.8 months
HbA1c, general health status, problem areas in diabetes, diabetes self-efficacy, recommended food score, and physical activity evaluated at baseline, 3.8 months, and 6.8 months after randomization
↓ HbA1c in all groups; ↑ exercise score, self-efficacy, and HbA1c level of individual training group compared to group education and control group
Randomized controlled trail; patient with type 2 diabetes ()
Five weekly sessions of social cognitive (self-efficacy) and self-regulatory (illness beliefs) theory-based program
Revised summary of self-care diabetes activities (at baseline, one week, three months, and nine months)
↑ Self-efficacy for exercise immediately and three-month postintervention; essential role illness beliefs in the patients’ quality of life, and self-efficacy in self-management behaviors
Randomized controlled trial; adults with type 2 diabetes ()
Three-week intervention program (diabetes factsheets and a DVD comprising patient stories (narratives) of type 2 diabetes management with follow-up at 4 weeks and 6 months)
Diabetes management self-efficacy scale (A/E DMSES) and self-care activities (SDSCA) at baseline and 4 weeks
Randomized controlled trial; overweight Asian Indian adults with prediabetes ()
Four-month diabetes prevention program on self-efficacy
Exercise-related self-efficacy was measured at baseline, core intervention completion (4 months), and annually until the end of follow-up (3 years or diabetes diagnosis)
↑ Self-efficacy at treatment completion, but this effect was not sustained over longer follow-up
