Validity and reliability of the Chinese version of Pediatric Quality of Life Inventory Version 3.0 Asthma Module

Abstract:

OBJECTIVE: To evaluate the reliability and validity of parent proxyreport scales of Pediatric Quality of Life Inventory Version 3.0 (PedsQLTM) Asthma Module (Chinese version). METHODS: Two hundred and thirty-three asthmatic children and their parents from the Children's Hospital of Chongqing Medical University were enrolled. Health related quality of life was assessed using the above mentioned PedsQLTM Asthma Module. The internal consistency was assessed using Cronbach's α coefficient, while its validity was tested through correlation analysis and exploratory factor analysis. RESULTS: The internal consistency reliability for Total Scale Summary Score (Cronbach's α=0.86), Asthma Score (Cronbach's α=0.80), Treatment Score (Cronbach's α=0.78), Worry Score (Cronbach's α=0.89) and Communication Score (Cronbach's α=0.93) were excellent. Seven major factors were extracted by factor analysis which basically matched the designed structure of the original version accounting for nearly 66% of the variance. Moderate to high correlations between items and the subscales were found, and the correlation coefficients ranged from 0.41 to 0.92(P＜0.01). CONCLUSIONS: The reliability and validity of the parent proxy-report scales of PedsQLTM 3.0 Asthma Module of the Chinese version are as good as the original version.［Chin J Contemp Pediatr, 2010, 12 (12):943-946］
