Verifying drug abuse prevention program effects using reciprocal best friend reports

Area of Science:

• Public Health
• Adolescent Psychology
• Substance Abuse Prevention

Background:

• Social influences-based programs are effective for drug abuse prevention.
• A common limitation is reliance on self-reported substance use data.
• Normative education is a key component of social influences programs.

Purpose of the Study:

• To evaluate the impact of normative education on adolescent alcohol and cigarette consumption.
• To assess the validity of normative education's effects using both self-reports and best friend reports.
• To determine if self-report bias undermines previous findings on normative education.

Main Methods:

• Analysis of data from 11,995 students in the Adolescent Alcohol Prevention Trial.
• Utilized self-reported and reciprocal best friend reports of substance use.
• Examined effects across eighth, ninth, and tenth grades in public school settings.

Main Results:

• Normative education significantly delayed the onset of alcohol use.
• A similar, though less pronounced, effect was observed for cigarette use.
• Findings were consistent across self-report and best friend report measures.

Conclusions:

• Normative education is a validated and effective strategy for adolescent drug abuse prevention in schools.
• The effectiveness of normative education is not solely attributable to self-report bias.
• This study provides strong evidence for implementing normative education in public school settings.
