  • Title: QUOTAC: QUestionnaire On day and night Time respiratory symptoms in Asthmatic Children -- a validity study.
    Author: van Zaane B, Droog RP, Stouthard ME, van Aalderen WM.
    Journal: J Asthma; 2007 Mar; 44(2):107-11. PubMed ID: 17454324.
    Abstract:
    The aim of this study was to validate the QUOTAC, a questionnaire on day and night time respiratory symptoms in asthmatic children. Validity was examined by measuring agreement between the QUOTAC and a self-report diary in children aged 6 to 16 years, divided in an asthma group and a control group. As an extra interest in our study a sum score was computed as a measure of the severity of asthma. This study shows that the QUOTAC is discriminative between asthmatic and healthy children and is a reliable and sensitive scale for measuring the severity of asthma. However, cut-off scores for mild, moderate, or severe asthma should be investigated in further research.
