Self-Efficacy and Confidence in Outcomes as Determinants of Self-Care Practices in Inner-City, African-American Women with Non-Insulin-Dependent Diabetes

The purpose of this study was to examine the extent to which perceived self-efficacy and confidence in outcomes, selected demographic variables, and disease characteristics (age, duration of diabetes, presence of documented complications) affect an individual's adherence over time to a diabetes regimen of home glucose testing, medication/insulin administration, diet, and exercise. A convenience sample of 118 inner-city, African-American women with type II, non-insulin-dependent diabetes mellitus receiving outpatient care at a large urban hospital were asked to complete measures of each of the psychosocial variables on two occasions, separated by an interval of 4 to 5 months, and coinciding with their next scheduled clinic visit. Bivariate and multivariate analyses at Times 1 and 2 demonstrated the ability of self-efficacy alone to explain diet, exercise, and home-testing behaviors while suggesting variability within individuals in sense of self-efficacy over time.
