There is no universally accepted and validated measure of asthma severity. For community research, clinical tests are too costly, and epidemiological assessments provide inadequate data on severity. Symptom measures may offer a practical alternative. This study assessed psychometric properties of symptom ratings of 91 asthmatic children. Reliability and validity of scales created from these items were examined. A sum scale of symptom ratings was internally consistent, reliable across time, and associated with concurrent health indices. This scale may be a practical measure of severity for use in community-based research.
目前尚无被普遍接受和验证的哮喘严重程度衡量标准。对于社区研究而言，临床试验成本过高，而流行病学评估提供的严重程度数据又不充分。症状测量可能提供一种实用的替代方法。本研究评估了91名哮喘儿童症状评分的心理测量特性。对由这些项目创建的量表的信度和效度进行了检验。症状评分的总和量表具有内部一致性，随时间推移可靠，且与同时期的健康指标相关。该量表可能是用于社区研究的一种实用的严重程度测量方法。
