Self report of smoking status is potentially unreliable in certain situations and in high-risk populations. This study aimed to determine the accuracy and acceptability of computer administered self-report of smoking status among a low socioeconomic (SES) population.
Clients attending a community service organisation for welfare support were invited to complete a cross-sectional touch screen computer health survey. Following survey completion, participants were invited to provide a breath sample to measure exposure to tobacco smoke in expired air. Sensitivity, specificity, positive predictive value and negative predictive value were calculated.
Three hundred and eighty three participants completed the health survey, and 330 (86%) provided a breath sample. Of participants included in the validation analysis, 59% reported being a daily or occasional smoker. Sensitivity was 94.4% and specificity 92.8%. The positive and negative predictive values were 94.9% and 92.0% respectively. The majority of participants reported that the touch screen survey was both enjoyable (79%) and easy (88%) to complete.
Computer administered self report is both acceptable and accurate as a method of assessing smoking status among low SES smokers in a community setting. Routine collection of health information using touch-screen computer has the potential to identify smokers and increase provision of support and referral in the community setting.
在某些情况下和高危人群中，自我报告的吸烟状况可能不可靠。本研究旨在确定在社会经济地位较低（SES）人群中，计算机管理的自我报告吸烟状况的准确性和可接受性。
邀请参加福利支持社区服务组织的客户完成横断面触摸屏计算机健康调查。完成调查后，邀请参与者提供呼气样本以测量呼出空气中的烟草烟雾暴露量。计算敏感性、特异性、阳性预测值和阴性预测值。
383 名参与者完成了健康调查，其中 330 名（86%）提供了呼气样本。在纳入验证分析的参与者中，59%报告为每日或偶尔吸烟者。敏感性为 94.4%，特异性为 92.8%。阳性预测值和阴性预测值分别为 94.9%和 92.0%。大多数参与者表示，触摸屏调查既愉快（79%）又容易（88%）完成。
在社区环境中，计算机管理的自我报告是评估 SES 较低的吸烟者吸烟状况的一种既可接受又准确的方法。使用触摸屏计算机常规收集健康信息有可能在社区环境中识别吸烟者并增加支持和转介服务。
