Development and Validation of the Parent-Preschoolers Diabetes Adjustment Scale (PP-DAS).

OBJECTIVE: This article extends work on a social-ecological model of caregiver adjustment and describes the: (a) development and (b) validation of the Parent-Preschoolers Diabetes Adjustment Scale (PP-DAS), a broad measure of caregiver adjustment.

METHODS: Participants were caregivers (nstudy1 = 51; nstudy2 = 177) of very young children (<6 years old) with Type 1 diabetes (T1D). In study 1, researchers and stakeholders collaborated to develop 92 items using the 5 domains of a social-ecological model of caregiver adjustment to the challenges of raising a very young child with T1D, and parents and researchers provided feedback on these items. In study 2, confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were used to examine the factor structure of the PP-DAS. Reliability and validity were also examined.

RESULTS: After review by parents and researchers, 52 items were removed resulting in the 40-item version used in study 2. The CFA demonstrated poor fit with the five proposed domains of the social-ecological model, so an EFA was conducted and supported a different five-factor solution. Twenty items were removed due to low factor loadings or communalities, resulting in a final 20-item measure. The PP-DAS demonstrated adequate internal consistency (α's = .73-.84), convergent validity with parent psychological functioning and self-efficacy in T1D management, and criterion validity with hemoglobin A1c and adherence.

CONCLUSIONS: The PP-DAS is a valid and reliable measure of adjustment in caregivers of very young children with T1D. The PP-DAS may help identify caregivers who are having adjustment difficulties and would benefit from additional support.
