The Chinese version of the pediatric quality of life inventory™ (PedsQL™) healthcare satisfaction generic module (version 3.0): Psychometric evaluation

Abstract

Background: Healthcare satisfaction is an important indicator in quality of healthcare evaluations. Instruments with psychometric evaluation for pediatric healthcare satisfaction in China have been rarely studied. The PedsQL™ 3.0 Healthcare Satisfaction Generic Module was a widely used instrument designed to measure parents' satisfaction of the healthcare for their children with chronic diseases. This study aimed to evaluate the psychometric properties of the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module.Methods: We used the standard procedure of cross-culture adaptation to develop the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module. We administered the scale to 354 parents with children experiencing chronic diseases from 5 third-grade class-A hospitals in Guangzhou by the convenience sampling method. The psychometric properties of the scale were evaluated.Results: The response rate was 94.4%. All the subscales reached the minimum reliability standard of 0.70 for Cronbach's alpha coefficient and the recommended test-retest reliability standard of 0.80 for intra-class correlation coefficients (ICCs). There were higher correlation coefficients between items and their hypothesized subscales than those with other subscales. Confirmatory factor analysis showed that the scale had adequate construct validity with the main indexes of goodness of fit CFI and RMSEA as 0.99 and 0.078, respectively.Conclusions: The results demonstrate that the Chinese version of the PedsQL™ 3.0 Healthcare Satisfaction Generic Module is a feasible instrument with adequate psychometric properties. © 2013 Li et al.; licensee BioMed Central Ltd.
