The Institute to Promote Athlete Health & Wellness (IPAHW) has kicked off a longitudinal study, funded by the National Institute on Drug Abuse (NIDA) to study myPlaybook. myPlaybook is an evidence-based behavioral intervention designed to reduce alcohol and other drug use and related consequences among student-athletes. This study is designed to optimize the critical components of the intervention while investigating the effect of the program and the specific pathways to behavior change. Seventy-four NCAA member institutions across all three divisions are participating in the study.
