Residual Effects of Intoxication on Student Performance

Intervention / Treatment
Detailed Description
The primary goal of the study is to assess the effect of heavy drinking on next day academic performance. A placebo-controlled 2-period crossover design will be used to compare the effects of dosing status on academic performance, with participants serving as their own controls. Participants are dosed on two separate occasions, once with non-alcoholic beverage and the other time with alcoholic beverage sufficient to raise blood alcohol to 0.10 g%. The morning after dosing, participants' academic performance is measured using a standardized achievement test (Graduate Record Exam). Participants' cognition is tested using the the Psychomotor Vigilance Test (PVT). Data on participants' demographics, family history of drinking problems and alcohol use. We are also collecting information on hangover symptoms and sleep quality the morning after dosing, in addition to participants' self ratings of academic performance. The procedure is conducted twice with one week in between, switching the individuals' dosing status, presenting a different, but comparable lecture and reading, and administering a different quiz based on the new lecture and reading and a different, but comparable standardized achievement exam. This design is intended to test the hypothesis that intoxication (0.10 g% BAC) with alcoholic beverage impairs next-day academic performance.
Participation involves a total of five sessions over a two week period. Participants are undergraduates who volunteer and meet inclusion criteria. Prior to enrollment, volunteers are screened to ensure they meet initial eligibility criteria. Eligible volunteers receive written instructions regarding participation and are scheduled for the study sessions. Participants report to the study site on the first session for an additional screening by the study physician and go through the informed consent process. Eligible participants report back the next week for their first dosing night where they receive several drinks (alcohol or placebo) sufficient to raise their Breath Alcohol Level (BrAC) to 0.10 g%; the amount of beverage administered is based on their body weight. Those receiving placebo receive the same total quantity of beverage as those receiving alcohol. Both alcohol-dosed and placebo-dosed participants are breath-tested after they have completed their required dose. Participants sleep at the study site and are monitored overnight. The next morning they are awakened and are escorted to the exam room for the performance trials. They return the next week for the second dosing night/dosing morning, and receive either alcohol or placebo, depending on what was administered the previous week, and take different but comparable performance tests.

Experimental: Alcohol then Placebo
Participants report for their first dosing night where they receive several alcohol drinks.
After a wash out period of 1 week they then return and receive several placebo drinks.
Participants sleep at the study site, are monitored overnight, and the next morning are awakened and escorted to the performance trials.

Participants report for their first dosing night where they receive several alcohol/beer drinks sufficient to raise their BrAC to 0.10 g%.
Participants are breath-tested after completing their required dose.
Participants return in a week for the 2nd session and receive placebo drinks.
Participants are breath-tested after completing their placebo drinks.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Self-reported Residual Effects of Heavy Drinking
Time Frame: next day
|
This outcome will be measured by the afternoon total mood disturbance score.
This is part of the Profile of Mood States Questionnaire (POMS).
POMS is a 35 item instrument with Likert responses from 0 to 4 where 0=not at all and 4=extremely.
Range of scores can be 0 to 140, lower scores are more favorable.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Cognitive Function in Response to Heavy Drinking
Time Frame: next day
|
This outcome measure will be assessed using the Visual Span Test- Backwards (VST-B).
This is the mean maximum span of words repeated backwards correctly.
Higher scores are more favorable
|
next day
|
Academic Function in Response to Heavy Drinking
Time Frame: next day
|
This outcome will be measured by the mean Graduate Record Exam (GRE) quantitative score.
The quantitative score can range from 200-800.
Higher scores are more favorable.
|
next day
|
Reaction Time Affected by Residual Effects of Heavy Drinking
Time Frame: next day
|
This outcome will be measured with the Continuous Performance Test (CPT) for reaction time in mean milliseconds (ms).
Lower reaction times are more favorable.
|
next day
|
Effectiveness of Psychomotor Vigilance Testing as a Fitness-for-duty Test
Time Frame: next day
|
This outcome will be assessed with the Psychomotor Vigilance Test (PVT) in median milliseconds.
The 10-min PVT measures sustained or vigilant attention by recording response times to visual (or auditory) stimuli that occur at random inter-stimulus intervals.
Lower number of milliseconds are associated with greater vigilant attention.
