Biochemical and self-report measures of cigarette smoking were obtained from a study population of eight-grade students who were enrolled in the Guilford County, North Carolina, school system during May 1980 and their mothers. A group of 386 adolescents provided self-reports before awareness of the biochemical evaluation, while a group of 1439 mothers encompassed unaware and aware observational conditions. Substantial crude agreement was found between carbon monoxide in alveolar air and questionnaire responses on recency of smoking, and the biochemical and self-report measures yielded similar descriptive estimates of smoking. Sensitivity and specificity for mothers, and specificity for the adolescents, exceeded 90%. Although only 64% of the adolescents classified as smokers according to the biochemical measure reported that they were smokers, most correlates of their smoking behavior were the same regardless of the measure that was used.
吸烟的生化指标和自我报告数据来自于1980年5月就读于北卡罗来纳州吉尔福德县学校系统的八年级学生及其母亲组成的研究群体。一组386名青少年在知晓生化评估之前提供了自我报告，而一组1439名母亲涵盖了不知情和知情的观察条件。发现肺泡空气中的一氧化碳与关于近期吸烟情况的问卷回答之间存在显著的粗略一致性，并且生化指标和自我报告数据得出了相似的吸烟描述性估计。母亲的敏感性和特异性以及青少年的特异性均超过90%。尽管根据生化指标被归类为吸烟者的青少年中只有64%报告自己是吸烟者，但无论使用何种指标，他们吸烟行为的大多数相关因素都是相同的。
