Effect of Comprehensive Prevention Software on Risk and Protective Factors in Adolescents - A Multi-site Study

2004 
This multi-site, randomized controlled study tests two hypotheses: (1) Self-directed use of comprehensive prevention training software will result in reduced risk and enhanced protective factors in adolescents and (2) Under real-world conditions, the software will be implemented as designed with the same favorable results. Overall effects of the Ripple Effects software at sites where implementation was high and dosage-correlated effects at sites where implementation was low support the first hypothesis. Students in the intervention group had higher grade point averages, less fatalistic thinking, fewer absences, less tardiness, and fewer disciplinary referrals than students in the comparison group. They also had lower perceptions of harm from, but higher disapproval of marijuana. Implementation under real-world conditions was 60%.
