BACKGROUND AND PURPOSE: Type 2 diabetes mellitus (T2DM) self-management among Hispanic adults occurs in a family context. Self-efficacy (SE) affects T2DM self-management behaviors; however, no instruments are available to measure family diabetes self-efficacy. The study's purpose was to test the psychometric properties of the Family Self-Efficacy for Diabetes Scale (FSE).
METHODS: Family members (n = 113) of adults with T2DM participated. Psychometric analysis included internal consistency reliability and concurrent and construct validity.
RESULTS: Internal consistency reliability was .86. Items loaded on 2 factors, Family SE for Supporting Healthy Behaviors and Family SE for Supporting General Health, accounting for 71% of the variance. FSE correlated significantly with 3 diabetes-related instruments.
CONCLUSIONS: The FSE is a reliable and valid instrument. Further testing is needed in diverse populations and geographic areas.
