Childhood Asthma Questionnaires

Name of Questionnaire

Childhood Asthma Questionnaire


There are three separate pediatric asthma scales grouped under this heading. The CAQ-A is designed for children aged 4-7, the CAQ-B for children 8-11, and the CAQ-C for children 12-16. All three versions tap quality of life and the level of distress caused by the disease. Responses are in the form of "smiley" faces, and the questionnaires are completed, at least for younger children, with the help of the parent.
