背景资料。儿童哮喘调查措施还没有在非英语人群中得到充分的测试。目的：测试英语和西班牙语症状量表测量儿童哮喘控制的可靠性和有效性。结果：由咳嗽、喘息、气短、哮喘发作、胸痛、夜间症状和总体感觉严重程度组成的8个条目的量表在英语和西班牙语中都有很好的心理测量学特性。该量表的信度(Cronbach‘s Alpha)在0.81到0.87之间，无论是语言还是时间框架。在两种语言中，量表的有效性得到了对临床状态变化的反应(病情缓解后症状评分降低，P<；0.001)以及与其他哮喘发病率指标(父母报告儿童问题：r=0.59-0.65；上学天数：r=0.38-0.67；失去活动天数：P=0.41-0.59)的中到强相关性(P<；0.001)的支持。尽管说西班牙语的人报告的某些症状的出现频率低于说英语的人，但不同语言的症状总结量表的信度和结构效度没有统计学差异。结论：一个可靠和有效的8个条目的量表可以用来衡量说西班牙语的低识字率人群对哮喘症状的控制。有必要进行更多的研究来评估哮喘措施的语言等价性。
BACKGROUND. Pediatric asthma survey measures have not been adequately tested in non-English-speaking populations.OBJECTIVES. To test the reliability and validity of an English and Spanish symptom scale to measure asthma control in children.SUBJECTS. Parents (54% Spanish-speaking; 61% not high school graduates) of 234 children seen in the emergency department for an asthma exacerbation.MEASURES. Parent report of frequency and perceived severity of child asthma symptoms during the beginning and after resolution of the exacerbation.RESULTS. An 8-item scale composed of reports of cough, wheezing, shortness of breath, asthma attacks, chest pain, night symptoms, and overall perceived severity had very good psychometric properties in both English and Spanish. The reliability (Cronbach's alpha) of the scale ranged from 0.81 to 0.87 for both languages and time frames. In both languages, the validity of the scale was supported by responsiveness to changes in clinical status (lower symptom score after resolution of the exacerbation, P < 0.001) and by moderate to strong correlations (P < 0.001) with other asthma morbidity measures (parent report of child bother: r = 0.59-0.65; school days lost: r = 0.38-0.67; and activity days lost: p = 0.41-0.59). There were no statistically significant differences in the reliability or construct validity of the summary symptom scale by language, although Spanish speakers reported a lower frequency of some symptoms than did English speakers.CONCLUSIONS. A reliable and valid 8-item scale can be used to measure control of asthma symptoms in Spanish-speaking populations of low literacy. Additional research to evaluate language equivalency of asthma measures is necessary.
