Abstract

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.

摘要

哮喘问卷是一个包含68个条目的生活质量量表，旨在对临床试验中的生活质量变化敏感。该问卷涵盖11个生活经历领域，最初的领域和条目集源自哮喘患者的六个定性焦点小组。对101名哮喘患者对最初101个条目集的回答进行的心理测量分析表明，尽管该量表是多领域的，但它是单维的，并且在使用783名患者进行的条目细化的另外三个阶段中重复了单维性的发现。该量表补偿了默认偏差，并允许使用“不适用”的回答类别。通过确认预期的组间差异证明了该量表的有效性，重测信度为0.948。
