title: Medication compliance in children with asthma.
abstract: A questionnaire to assess compliance with prescribed therapy was completed by 200 children with asthma. The validity of the questionnaire was assessed objectively by measuring plasma theophylline concentrations in 37 subjects and by weighing metered dose aerosol canisters before and after use in 19 subjects. The average compliance was 67.9%. The close agreement between answers to the questionnaire and the objective measurements of compliance indicated that most participants recalled the drug regimens accurately. Good compliance was related to whether Australia was the parents' country of origin, to knowledge of the disorder and to comprehension of medication but was not related to perception of the severity of the illness. This study demonstrates that compliance is relatively poor even in a clinic population which attends regularly and appears well-motivated.
