One of the most promising instruments in measuring pediatric HRQOL emerged in recent years is the Pediatric Quality of Life Inventory PedsQL . The PedsQL Asthma Module one of the PedsQL disease-specific scales was designed to measure HRQOL dimensions specifically tailored for pediatric asthma. The present study is aimed to evaluate the psychometric properties of the Chinese version of the PedsQL Asthma Module. Methods The PedsQL Asthma Module was translated into Chinese following the PedsQL Measurement Model Translation Methodology. The Chinese version scale was administered to 204 children with asthma and 337 parents of children with asthma from four Triple A hospitals. The psychometric properties were then evaluated. Results The percentage of missing value for each item of the scale ranged from to . All child selfreport subscales and parent proxy-report subscales approached or exceeded the minimum reliability standard of for alpha coefficient except 3 subscales of Young Child aged 5-7 self-report alphas ranging from to . Test-retest reliability was satisfactory with intraclass correlation coefficients ICCs which exceeded the recommended standard of in all subscales. Correlation coefficients between items and their hypothesized subscales were higher than those with other subscales. The PedsQL Asthma Module distinguished between outpatients and inpatients. Patients with mild asthma reported higher scores than those with moderate severe asthma in majority of .
