Reliability and Validity of the Children’s Health Survey for Asthma–Child Version

Background: Updated asthma guidelines stress the importance of obtaining patient-reported information about symptoms and limitations to develop effective treatment and education plans. In pediatrics, reporting has often relied on parent proxy but there is increasing recognition that children can provide input on their own health status. The Children’s Health Survey for Asthma (CHSA) has become a well-recognized tool for parent report of child asthma-related health status. To collect data directly from children and adolescents, we developed a companion pencil-and-paper instrument, the CHSA-Child Version (CHSA-C).

Methods: The CHSA-C includes three scales—Physical Health, Child Activities, and Emotional Health (scoring 0–100; higher scores = better/more positive outcomes). We evaluated reliability (internal consistency; test–retest) and validity. Variations were examined by gender, income, and race/ethnicity. Results:...
