简要总结
The goal of this clinical trial is to examine whether dynamic visual noise (DVN), a short video array of rapidly moving black and white squares, reduces cravings for and consumption of alcohol in college students who drink alcohol and experience cravings for alcohol at least once a week on average. A second goal of this clinical trial is to examine whether changes in attentional bias towards alcohol (that is, the tendency to pay greater mental and visual attention towards alcohol over other things in one's environment) is a mechanism by which DVN reduces alcohol cravings and consumption.
Researchers will compare DVN to static visual noise (SVN), which is a still image of black and white squares that has been used as a control condition for DVN in prior literature.
Participants will:
- Visit the laboratory once to complete the baseline data collection
- Watch the DVN or SVN every day for seven days (including the day of the laboratory visit)
- Complete daily follow-ups for six days following the day of the laboratory visit
- Complete a final follow-up on the seventh day following the laboratory visit

结局指标
主要结局
Strength of Alcohol Craving
时间窗: Baseline and 1-week follow-up
Strength of alcohol craving will be measured using the Craving Experiences Questionnaire - Strength (CEQ-S). The measure inquires about the individual's past-week craving experiences. Higher average scores indicate stronger past-week cravings. Changes in mean craving will be calculated as changes in mean strength of past-week alcohol craving at follow-up relative to baseline for each condition.
Frequency of Craving
时间窗: Baseline and 1-week follow-up
Frequency of alcohol craving will be measured using the Craving Experiences Questionnaire - Frequency (CEQ-F). The measure inquires about the individual's past-week craving experiences. Higher average scores indicate more frequent past-week craving. Changes will be calculated as changes in mean frequency of past-week alcohol craving at follow-up relative to baseline for each condition.
Alcohol Consumption
时间窗: Baseline and 1-week follow-up
At baseline and follow-up, participants will complete the Daily Drinking Questionnaire (DDQ) to indicate the extent of their past-week alcohol consumption. Higher total scores indicate more past-week alcohol consumption. Changes will be calculated as changes in mean past-week alcohol use at follow-up relative to baseline for each condition.
Attentional Bias towards Alcohol
时间窗: Baseline and 1-week follow-up
Attentional bias will be measured at the initial laboratory session and at the 1-week final follow-up via the Alcohol Visual Probe task. Changes will be examined as mean changes in reaction time at follow-up minus reaction time at baseline for each condition.
次要结局
- Immediate Changes in Strength of Alcohol Craving Before and After DVN/SVN Task(Baseline)
- Immediate Changes in Strength of Craving Before and After DVN/SVN(1-Week Intervention Period, Between Baseline Visit and 1-week Follow-Up)
