Psychometric properties and normative data for the parent version of the diabetes independence survey.

The parent version of the Diabetes Independence Survey measures parents' perceptions of their children's mastery of 38 diabetes self-care skills. The instrument was administered to 648 parents of 622 children with insulin-dependent diabetes mellitus, ages 3 and 18 years, at seven different pediatric medical centers. Data confirming the internal consistency, interrater reliability, construct validity, and concurrent validity of the instrument are presented in this paper. Age-adjusted normative data for total scores on the instrument as well as item-by-item data on the ages at which mastery of each skill was reported by 25%, 50%, and 75% of parents also are discussed. The Diabetes Independence Survey can be used as a reliable, valid, and efficient research tool for assessing the growth and development of diabetes knowledge and skills among children and adolescents, and as a screening instrument and program evaluation tool for clinical purposes.
