背景资料：虽然目前有评估儿童哮喘严重程度的临床诊断和治疗的措施，有没有标准有效的措施，以评估儿童哮喘严重程度的大规模流行病学研究。目的：开发和测试儿童哮喘严重程度量表（CHAS）的临床有效性，并确定不同的症状，药物使用，和卫生保健访问的参与者的特点。方法：897名12岁以下的哮喘儿童从一般儿童人群中选出。儿童是从康涅狄格州六家为布里奇波特、纽黑文、哈特福德和丹伯里的大量少数族裔人口提供服务的医院以及一家为马萨诸塞州中南部提供服务的医院进行的筛查问卷中选出的。通过家庭访谈每月收集一次儿童哮喘严重程度前瞻性队列研究的10个月基线数据。家庭访谈解决了日常症状，药物使用和卫生保健访问的问题。结果：CHAS具有足够的初步内容、结构和预测效度。尽管症状相似，有卫生保健利用和药物治疗的差异，根据种族和民族，保险状况，家庭收入，和产妇education.Conclusions：CHAS是一个潜在的有用的措施，哮喘的严重程度为大规模的流行病学研究。看来CHAS具有足够的临床性能。
Background: Although there are current measures to evaluate childhood asthma severity for clinical diagnosis and treatment, there is no standard valid measure to evaluate childhood asthma severity for large-scale epidemiologic studies.Objectives: To develop and test a childhood asthma severity scale (CHAS) for clinimetric validity and to determine differences in symptoms, medication use, and health care visits by participant characteristics.Methods: Eight hundred ninety-seven actively asthmatic children under the age of 12 years were selected from a general population of children. Children were selected from a screening questionnaire administered at six Connecticut hospitals that serve large minority populations in Bridgeport, New Haven, Hartford, and Danbury and one hospital serving south central Massachusetts. Twelve-month baseline data for a prospective cohort study of childhood asthma severity were collected on a monthly basis through home interviews. Home interviews addressed questions on daily symptoms, medication use, and health care visits. A severity scale was constructed using three dimensions: symptoms, medication use, and health care visits.Results: CHAS has sufficient preliminary content, construct, and predictive validity. Despite similarities in symptoms, there were health care utilization and medication differentials according to race and ethnicity, insurance status, family income, and maternal education.Conclusions: CHAS is a potentially useful measure of asthma severity for large-scale epidemiologic studies. It seems that CHAS has sufficient clinimetric properties.
