Purpose: The aim of this study was to develop and evaluate the psychometric properties of a questionnaire to assess asthma-related quality of life among children with asthma. Design: A cross-sectional survey study of 474 participants recruited from Taiwan for instrument development and psychometric testing. Methods: The questionnaire was developed in 3 stages. In the first stage, the findings of a previous qualitative study were used to construct the Asthma-Related Quality of Life Scale (ARQOLS). In the second stage, the scale's psychometric properties (content validity index and item analysis) were established. Finally, the internal consistency (Cronbach's alpha) of the ARQOLS was examined in a sample of 474 children with asthma, aged 6-14 years. Construct validity was established by principal component analysis with varimax rotation. Findings: The 35-item ARQOLS exhibited better then expected reliability with Cronbach's alpha 0.96. Five factors emerged from factor analysis, giving a total variance of 61.02%. The 5 factors (and their Cronbach's alpha coefficients) were restriction of social life (.90), physical disturbances from signs/symptoms (.91), limitation of physical activity (.88), daily inconveniences in managing the disease (.81), and emotional distress (.87). Conclusion: These preliminary psychometric findings support the internal consistency and construct validity of the ARQOLS, which is a multidimensional concept comprised of restriction of social life, physical disturbances from signs/symptoms, limitation of physical activity, daily inconveniences in managing the disease, and emotional distress. Thus, this questionnaire can serve as an effective and practical tool for evaluating children's quality of life as affected by asthma. Key words: asthma, quality of life, psychometrics, children
