【 摘 要 】

BackgroundWith increasing cancer incidence and decreasing cancer mortality, there is a growing need for a valid and culturally adapted tool to measure health-related quality of life in children with cancer. This study validated the DISABKIDS Chronic Generic Module (DCGM-37) in Chinese children and adolescents with cancer.MethodsThe DCGM-37 was translated and adapted for use in China following the guidelines from its copyright holders. In total, 140 children and adolescents with cancer and their guardians were included in this cross-sectional study. Internal consistency and test-retest reliability were evaluated. Convergent validity was examined using Pearson correlation between the DCGM-37 and the PedsQL 4.0 Generic Core Scale. Dimensionality was clarified using exploratory factor analysis. Discriminant validity was evaluated by comparing DCGM-37 scores by sex, age, family income, and clinical characteristics.ResultsInternal consistency (Cronbach’s alpha 0.91) and test–retest reliability were good (intraclass correlation coefficient 0.87, 95% confidence interval 0.73–0.94). Strong correlations between the DCGM-37 and the PedsQL 4.0 (r = 0.83) suggest good convergent validity. Six factors explained 51.94% of the total variance. Children with leukemia scored higher than those with sarcoma in all subscales (effect size ranged from 0.39 to 0.83), especially the “social exclusion” subscales (effect size 0.83). Small to moderate differences (effect size ranged from 0.38 to 0.58) were observed by sex, age, and family income. Neither floor nor ceiling effects were observed.ConclusionThe DCGM-37 is reliable and valid for measuring health-related quality of life in Chinese children and adolescents with cancer.
