Objective: To investigate the effect of a video intervention, Managing Your Diabetes Medicines, on patient self-efficacy, problems with using medication, and medication adherence in a rural, mostly African American population.
Methods: Patients selected their problem areas in medication use and watched one of nine 2-min videos with a research assistant at a clinic or pharmacy and were given an access code to watch all the videos at their convenience. Outcomes were measured at baseline and 3-month follow-up.
Results: Fifty-one patients were enrolled; 84% were African American and 80% were female (mean age: 54 years). Seventy-three percent watched at least one module after the initial visit. Improved self-efficacy was associated with a decrease in concerns about medications (r=-0.64). Low literate patients experienced greater improvement in self-efficacy than more literate patients (t=2.54, p=0.02). Patients' mean number of problems declined from 6.14 to 5.03. The number of patients with high or medium adherence rose from 33% at baseline to 43% at 3-month follow-up.
Conclusions: A practical, customized video intervention may help improve patient self-efficacy, reduce problems with medication use, and improve medication adherence in diabetes patients.
Practice implications: Providers should consider implementing technology-based interventions in the clinic to address common problems that patients have with self-management.
