The purpose of this study was to determine whether a telecommunications diabetes self-management (DSM) intervention would improve health-related outcomes among frontier participants with diabetes. A one-group pre-test/post-test quasi-experimental design with two groups of participants was used. Differences between pre and post-test periods on measures of physical and emotional health, knowledge of diabetes, and self-care behaviors were measured. Overall, participants did better along measures of blood pressure, HbA(1c), self-efficacy, knowledge of diabetes, understanding of DSM, monitoring behaviors, and reported less personal and social disruption from diabetes. Six-month follow-up results showed continued positive outcomes.
