哮喘问卷是一个68项的生活质量量表，旨在对临床试验中的生活质量变化敏感。 该问卷涵盖了11个领域的生活经验，最初的领域和项目集来自六个定性的重点小组的哮喘患者。 101名哮喘患者的反应，最初的101个项目集的心理测量学分析表明，规模是一维的，尽管是多域，并在进一步的三个阶段的项目细化使用783例重复的单维度的发现。 该量表补偿了默认偏差，并允许“不适用”的回答类别。 量表的有效性通过确认预期的组间差异得到证实，重测信度为0.948。
The Asthma Questionnaire is a 68-item quality of life scale designed to be sensitive to quality of life changes in clinical trials. The questionnaire covers 11 domains of life experience, the initial domain and item sets being derived from six qualitative focus groups of asthma patients. Psychometric analysis of responses of 101 asthma patients to the initial 101-item set showed the scale to be unidimensional despite being multi-domain, and the finding of unidimensionality was replicated during the further three stages of item refinement using 783 patients. The scale compensates for acquiescence bias as well as allowing a 'not applicable' response category. Validity of the scale was demonstrated by confirmation of expected group differences and the retest reliability was 0.948.
