Does puff topography measurement alter smoking behavior?

描述(由申请人提供)： 烟幕地形测量在阐明维持正常烟草使用的因素方面起着重要作用。通常，在实验室环境中通过基于吹嘴的台式设备来评估地形。最近，一种基于口罩的便携式设备可以在自然主义环境中使用。然而，任何环境中的吸烟行为都可能受到测量设备(即口罩)的影响。了解基于口罩的测量设备改变行为的程度至关重要，需要将基于实验室的和便携式设备与基于非口罩的测量进行比较。 这份提案描述了两项研究。第一项研究将基于口罩的台式和便携式地形测量与参与者在实验室吸烟的视频记录进行了比较。第二项研究比较了研究1中更自然的口罩设备和非实验室环境中的视频记录。这两项研究都使用了30名吸烟者和受试者内的设计，以调查口罩是否影响各种喷雾地形变量，包括喷烟数量、持续时间和喷烟间隔。该项目的结果将有助于最大限度地提高未来依赖于烟幕地形评估的研究的有效性。进行这项研究将提供与与人类参与者一起负责任地进行研究相关的宝贵经验，以及与跨不同研究站点的数据收集、分析和报告相关的问题。这些经历将帮助我实现成为一名独立的药物滥用研究人员的目标。

DESCRIPTION (provided by applicant): Puff topography measurement plays an important role in elucidating the factors that maintain regular tobacco use. Generally, topography is assessed in laboratory settings via mouthpiece-based, desktop devices. Recently, a portable mouthpiece-based device became available for use in naturalistic settings. However, smoking behavior in any setting may be influenced by measurement equipment (i.e., the mouthpiece). Understanding the extent to which mouthpiece-based measurement equipment alters behavior is critical, and will require comparison of laboratory-based and portable devices with nonmouthpiece-based measurement. This proposal describes two studies. The first compares mouthpiece-based desktop and portable topography measurement with video recordings of participants' smoking in a laboratory. The second compares the more naturalistic mouthpiece-based device from study 1 with video recordings in a non-laboratory environment. Both studies use 30 smokers and within-subject designs to investigate whether a mouthpiece influences a variety of puff topography variables, including puff number, duration, and interpuff interval. Results from this project will help maximize the validity of future studies that rely on puff topography assessment. Conducting this research will provide valuable experience related to the responsible conduct of research with human participants, as well as issues related to data collection, analysis, and reporting across diverse research sites. These experiences will help me achieve my goal to become an independent drug abuse researcher.
