Work-related asthma (WRA) is under-recognized and delays in recognition contribute to long-term morbidity. The objective of the project was to develop a WRA screening questionnaire for use by primary care providers in the assessment of individuals with asthma, and to evaluate the respondent burden, test re-test reliability and face validity of the questionnaire.
A literature search was undertaken and an expert advisory committee was convened. A questionnaire was drafted and assessed for feasibility of use and content validity. The study enrolled patients with asthma attending outpatient clinics and an asthma education center. Participants were asked to respond to the questionnaire on two occasions, and comment on the content (face validity) and ease of completion (respondent burden). Ethics approval was obtained from an institutional review board.
A 14-item self-administered screening questionnaire was created. Thirty-nine participants were recruited, and 26 participants completed a second administration of the questionnaire. The items on the relation of asthma symptoms to work demonstrated substantial agreement between testings. The workplace exposures items were found to have good reproducibility. The majority of participants denied that items were repetitive, not useful or difficult to understand.
We have developed a WRA screening questionnaire designed to aid primary care providers in the recognition of possible WRA. The tool exhibited content and face validity, good test re-test reliability and low respondent burden. Participant feedback is being considered in revisions of the questionnaire.
职业性哮喘（WRA）未得到充分认识，而诊断延迟会导致长期发病。本项目的目的是开发一种WRA筛查问卷，供初级保健提供者用于评估哮喘患者，并评估问卷的应答负担、重测信度和表面效度。
进行文献检索并召集专家咨询委员会。起草了一份问卷，并对其使用可行性和内容效度进行评估。该研究纳入了在门诊诊所和哮喘教育中心就诊的哮喘患者。参与者被要求两次回答问卷，并对内容（表面效度）和填写的难易程度（应答负担）发表意见。获得了机构审查委员会的伦理批准。
创建了一份包含14个条目的自填式筛查问卷。招募了39名参与者，其中26名参与者完成了问卷的第二次填写。关于哮喘症状与工作关系的条目在两次测试之间显示出高度一致性。发现工作场所暴露条目具有良好的可重复性。大多数参与者否认条目重复、无用或难以理解。
我们开发了一种WRA筛查问卷，旨在帮助初级保健提供者识别可能的WRA。该工具具有内容效度和表面效度，重测信度良好，应答负担低。问卷修订时会考虑参与者反馈。
