PROSPER: The Most Effective Prevention Program Ever?

January 11, 2018

A new drug and alcohol prevention program, PROSPER, has published its 6.5 years follow-up data. Based on the well designed and randomized methodology,  it is showing significant results compared to other approaches.  At the 6.5-year follow-up (end of 12th grade) it demonstrated community-wide reductions of 10-35% in illicit drug use initiation by youth who were non-users in 6th grade (prior to program delivery). It also achieved moderate reductions in substance use for the full sample – non-users and users (e.g., 14% lower likelihood of past-month cigarette use).  Interestingly, delaying onset of drug and alcohol involvement, so predictive on subsequent using careers, was very compelling in this study.
