OBJECTIVE--To test the psychometric properties of the short form of the Chinese version Diabetes Quality of Life for Youth scale (C-DQOLY-SF). RESEARCH DESIGN AND METHODS--A 30 -item C-DQOLY-SF was administered to 371 adolescents with type 1 diabetes. Exploratory and confirmatory factor analysis, correlation with [HbA.sub.1c], internal consistency, and test-retest reliability were used to examine the psychometric characteristics of C-DQOLY-SF. RESULTS--A 25 -item questionnaire with three correlated second-order factor structures best fitted data. Scores on the 25-item C-DQOLY-SF significantly correlated with [HbA.sub.1c] values. Cronbach's α and ICCs of each scale and subscale ranged from 0.77 to 0.90 and from 0.70 to 0.92, respectively. CONCLUSIONS--The C-DQOLY -SF has satisfactory reliability and validity. The C-DQOLYSF can be conveniently used in clinical settings to assess the quality of life of adolescents with type 1 diabetes., Pediatric health care providers are challenged to improve quality of life (QOL) in adolescents with type 1 diabetes (1).
