The objective of this research was to develop and validate the Diabetes Family Adherence Measure (D-FAM), a comprehensive and up-to-date tool designed for the assessment of adherence-related parenting behaviors for youth with type 1 diabetes (T1D). Further, this article outlines an empirical approach for scale design. First, experts reviewed a battery of potential items to create a preliminary version of the D-FAM. Subsequently, 165 youth with T1D and their families completed an initial administration. A parsimonious measure resulted, consisting of 19 items with 4 additional validity items. Factor analysis identified supportive, coercive, control, and monitoring subscales. D-FAM factors were generally associated with both adherence and health status (HbA1c [glycosolated hemoglobin]), as well as with extant scales of family functioning. Strong internal consistency, test-retest reliability, and construct-convergent reliability were obtained. This initial evaluation of the D-FAM suggests utility for efficient evaluation of family functioning related to adherence and glycemic control for research and clinical purposes.
