In the setting of a prepaid medical care plan, self-administered questionnaires were an accurate source of information on smoking habits and the standard against which the physiologic measures of smoking, serum thiocyanate, and expired carbon monoxide, must be judged. Questionnaire responses were internally consistent and highly reproducible. In contrast, the physiologic measures had low overall sensitivity as tests of current tobacco exposure (0.72). Their sensitivity was improved by utilizing the self-reported information.
在预付费医疗保健计划的背景下，自行填写的问卷是吸烟习惯信息的准确来源，也是评判吸烟的生理指标（血清硫氰酸盐和呼出一氧化碳）的标准。问卷回答在内部是一致的，并且具有高度的可重复性。相比之下，作为当前烟草暴露的检测方法，这些生理指标的总体敏感性较低（0.72）。通过利用自我报告的信息，它们的敏感性得到了提高。
