A-SIDE: Video simulation of teen alcohol and marijuana use contexts.

Objective: This investigation examined the concurrent validity of a new video simulation assessing adolescent alcohol and marijuana decision making in peer contexts (A-SIDE).

Method: One hundred eleven youth (60% female; age 14-19 years; 80% White, 12.6% Latino; 24% recruited from treatment centers) completed the A-SIDE simulation, self-report measures of alcohol and marijuana use and disorder symptoms, and measures of alcohol (i.

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.
