C-SIDE: drinking simulation for college students.

OBJECTIVE: Our goals were to develop a realistic simulation of collegiate drinking contexts and evaluate the predictive validity of this methodology.
METHOD: After methods development, 88 incoming students (61% women) completed measures of alcohol consumption, alcohol expectancies and motives, and the Collegiate-Simulated Intoxication Digital Elicitation (C-SIDE). Eight months later, students reported recent drinking behavior and alcohol-related consequences.
RESULTS: Willingness to drink alcohol on the C-SIDE predicted high-risk drinking at the end of the students' first year above and beyond baseline consumption. Accepting offers of food/nonalcoholic beverages across contexts predicted lower scores on the Alcohol Use Disorders Identification Test 8 months later. Drinking game contexts elicited different levels of behavioral willingness; a game with explicit heckling elicited less drinking willingness than one in a smaller and more casual environment.
CONCLUSIONS: These findings support the integration of social context into the assessment of alcohol-related decision making and the further development of strategies to understand context-dependent phenomena.
