Development and validation of a home blood glucose monitoring self-efficacy scale for patients with diabetes
摘要
Accurate home blood glucose monitoring is crucial for diabetes self-management, yet technical and behavioral errors often compromise accuracy.
ObjectiveThe purpose of this methodological study was to develop and validate the Home Blood Glucose Monitoring Self-Efficacy Scale (HBGM-SES) for adults with diabetes.
MethodsA total of 300 adults with diabetes were recruited from a training and research hospital in Türkiye between December 2023 and November 2024. Construct validity was assessed using exploratory and confirmatory factor analyses. Known-group validity was evaluated with t-tests and one-way ANOVA. Reliability was examined using internal consistency and test–retest analyses.
ResultsThe overall Cronbach’s α was .84, and the test–retest reliability coefficient was .82. Content validity was .97. Confirmatory factor analysis supported a three-factor structure with acceptable model fit (χ2/df = 2.068, RMSEA = .06, CFI = .90, IFI = .90, TLI = .90).
ConclusionThe HBGM-SES is a valid and reliable instrument for assessing self-efficacy in home blood glucose monitoring among adults with diabetes. The scale may help health professionals identify training needs and evaluate the impact of educational interventions, particularly in low-resource settings.
