This study evaluates the impact of a pipeline assessment (salivary cotinine determination) on the accuracy of self-reported use of cigarettes and smokeless tobacco by 160 rural seventh- and eighth-grade males ranging in age from 12 to 16. Half of them were randomly assigned to complete a questionnaire on tobacco use prior to revealing the biochemical validation materials and collecting samples. The others had the samples collected prior to receiving and completing the questionnaires. The questionnaire-first group reported significantly greater smokeless tobacco use than did the pipeline-first group. Only for the latter were their self-reports significantly corroborated by the cotinine results. These results suggest that the utilization of a biochemical pipeline not only can improve self-reported tobacco use but also may help identify perceptions about the social desirability of using harmful substances.
本研究评估了一项管道评估（唾液可替宁测定）对160名年龄在12至16岁之间的农村七年级和八年级男性自我报告的香烟和无烟烟草使用情况准确性的影响。其中一半被随机分配在揭示生化验证材料并收集样本之前完成一份关于烟草使用的问卷。另一半则在收到并完成问卷之前收集样本。先填写问卷组报告的无烟烟草使用量明显高于先进行管道评估组。只有后者的自我报告得到了可替宁结果的显著证实。这些结果表明，采用生化管道评估不仅可以改善自我报告的烟草使用情况，还可能有助于识别对使用有害物质的社会期望的看法。
