Abstract

A questionnaire was designed for completion by parents of asthmatic children aged from 5-14 years that provides scales of good content validity and internal reliability for the measurement of perceived disability, perceived nocturnal symptoms, and perceived daytime symptoms. We hope that this questionnaire will be included in future clinical studies of these patients.
