Clinical Trial Summary
The overall goal is to pilot test and establish a procedure for video-assisted alcohol
topography and explore its utility as an indicator of alcohol use disorder. There are 4
phases to this study: 1) pre-screening by phone; 2) in-person screening appointment; 3) the
first alcohol drinking session with videotaping; and 4) follow-up appointment for retest.
Description:
Alcohol use especially high-risk drinking remains a serious public health concern. Recent
calls for "precision intervention" require more in-depth understanding of drinking behavioral
patterns for more individualized treatment. Currently, alcohol research has relied on
self-reported questionnaire or biomarkers to measure alcohol use. However, self-reports are
often subjected to social desirability bias or recall errors; whereas biomarkers are prone to
measurement errors, confounders for false positives, and individual variations in alcohol
metabolism. There is need for an objective, reliable, and nonintrusive way to measure alcohol
use with high ecological validity.
Topography can provide objective measures of consumption behavior patterns in fine grained
detail. While it has been widely used in tobacco research, alcohol topography has not been
well-studied. Smoking topography has been shown to provide indicative information for
nicotine dependence. The investigators hypothesize that alcohol topography can also be used
as an objective measure indicative of alcohol use disorder. In this project, the
investigators propose to conduct a video-assisted drinking topographical study. The main
objectives of this study include: (1) characterize drinking behavioral patterns by converting
videotaped drinking episodes into various drinking related parameters (e.g., sipping
frequency, sipping interval, sipping duration, rest duration, sipping amount, and etc.); (2)
compare drinking behavioral patterns across groups defined by drinking status (social vs.
heavy drinkers) and mental health status (depressed vs. non-depressed); and (3) use advanced
nonlinear modeling to quantify the behavioral pattern and to derive potential indicators for
alcohol use disorder.
This will be the first study to ever use videotaped topography to analyze alcohol drinking
behavioral pattern using a quantum model and link it to alcohol use disorder. The study will
be conducted in the simulated bar laboratory located in Yon Hall at the University of Florida
(UF). Conducting alcohol topography in such a setting greatly enhances ecological validity,
further increasing the capacity of this method to capture real life drinking patterns and to
potentially detect alcohol use disorder.
