Brief Summary

Excessive alcohol consumption among college students continues to be a serious public health concern associated with a wide range of negative consequences. Brief computer-based social norms interventions, including personalized normative feedback (PNF), have shown consistent effects in reducing problematic drinking in this population, and there is some evidence that in-lab computer-delivered interventions may be more effective than remote interventions. Most studies have been conducted using generous incentives which may reduce the feasibility of dissemination on a larger scale and may undermine trial efficacy. In accordance with NIAAA aims, this research aims to (a) investigate delivery modality (i.e., in lab versus remotely) and incentives as important factors affecting the efficacy of PNF interventions and (b) develop intervention strategies that facilitate wider dissemination of inexpensive empirically-supported brief interventions for college students, thereby reducing problem drinking during a high-risk time period.

Outcome Measures

Primary Outcomes (5)

Number of drinks in past month - Timeline Follow-back (TLFB)
This measure asks participants to indicate how many drinks they consumed on each day of the previous month. Scores are summed.
1 month
Number of drinks on a typical week - Daily Drinking Questionnaire (DDQ)
Participants are asked how many drinks they typically drink on each day of a typical week. These values are summed to create a drinks per week score. From Collins, Parks, and Marlatt (1985).
3 months
Number of peak drinks consumed
Participants are asked to indicate the maximum number of drinks consumed on one occasion.
One month
Alcohol-related consequences: Brief Young Adult Alcohol Consequences Questionnaire (BYAACQ)
A measure of 27 alcohol consequences. Participants indicate whether they have experienced the consequence or not and responses are summed to create a total score.
One month
Alcohol-related consequences: Rutgers Alcohol Problems Index (RAPI)
A measure of alcohol consequences. Participants indicate the frequency with which they have experienced each consequence; responses are summed to create a total score.
3 months
