OBJECTIVE The objective of the study was to report on measurement properties revised and updated Pediatric Quality Life Inventory (PedsQL) 3.2 Diabetes Module for children, adolescents, young adults with type 1 diabetes. RESEARCH DESIGN AND METHODS 33-item PedsQL Generic Core Scales were completed in a 10-site national field test by 656 families patients ages 2–25 years RESULTS 15-item Symptoms Summary Score 18-item Management derived from factor analysis items. Scores evidenced excellent reliability (patient self-report α = 0.88–0.90; parent proxy 0.89–0.90). demonstrated construct validity through medium large effect size correlations Total Scale (r 0.43–0.67, P < 0.001). HbA1c significantly correlated −0.21 −0.29, Minimal clinically important difference scores ranged 5.05 5.55. CONCLUSIONS may be useful as standardized patient-reported outcomes diabetes symptoms management clinical research, trials, practice
