|Botvin, G.J. & Griffin, K.W. (2012). Long-term outcomes from Blueprints model programs: Life Skills Training. Presented at 2012 Blueprints for Violence Prevention conference. San Antonio, TX, April 11-14, 2012.
The study tracked teens who participated in the Botvin LifeSkills Training (LST) program as 7th graders and found that their participation in the program produced long-lasting reduction in drug use 12 years later. The study assessed LSTé─˘s impact on young adults in their early to mid-20s who received the program when they were in the 7th grade. The results of the study found that participants were 23% less likely to have ever used illicit drugs than were individuals who did not receive the LST program. They were also 22% less likely to have used marijuana and 26% less likely to have engaged in non-medical pill use (such as amphetamines, barbiturates, and tranquilizers). Over 2,000 individuals participated in the follow up study; their average age at the 12-year follow-up was 24.
