Evaluation of a Cognitive-Behavioral Game Design-Based Mobile Game on Alcohol Use for Adolescents.

Objective: Determine the effectiveness of a cognitive behavioral game design (CBGD) based mobile game as an alcohol use intervention. Materials and Methods: Experimental design with 140 participants randomly assigned to either play a mobile game (n = 69) or watch a video documentary (n = 71). Results: Both groups displayed a decrease in intent to use and an increase in knowledge. The video intervention was superior in affecting actual use. Conclusion: Mobile game affects intent to use and is superior to the video in affecting knowledge.
