2) adolescents in the game condition training will be more motivated to complete the training compared to adolescents in the placebo/traditional training condition

3) adolescents in the game condition training will drink less heavily after training compared to adolescents in the placebo/traditional training condition.

1) pre-assessment + first training session

2) second training session + behavioral control assessment

3) third training session

4) fourth training session + post-assessment

5) brief 3 month follow-up by email

1) serious game training condition
