A cognitive-behavioral approach to substance abuse prevention

Area of Science:

• Adolescent Psychology
• Public Health Interventions
• Substance Abuse Prevention

Background:

• Substance abuse is a significant public health concern among adolescents.
• Existing prevention programs often lack comprehensive life skills training.
• The role of program implementers (peer leaders vs. teachers) in effectiveness is understudied.

Purpose of the Study:

• To evaluate a 20-session cognitive-behavioral substance abuse prevention program for seventh graders.
• To assess the program's impact on intrapersonal and interpersonal pressures related to substance use.
• To compare the effectiveness of peer leader versus classroom teacher implementation.

Main Methods:

• Quasi-experimental design involving 1,311 seventh-grade students across 10 suburban New York junior high schools.
• Intervention focused on developing life skills and resistance tactics against substance use (smoking, excessive drinking, marijuana).
• Comparison of program outcomes based on implementation by older peer leaders versus regular classroom teachers.

Main Results:

• The cognitive-behavioral program significantly reduced cigarette smoking, excessive drinking, and marijuana use when delivered by peer leaders.
• Significant positive changes were observed in cognitive, attitudinal, and personality variables, promoting non-substance use.
• Peer-led implementation demonstrated greater efficacy compared to teacher-led implementation.

Conclusions:

• A broad-spectrum cognitive-behavioral approach is effective for adolescent substance abuse prevention.
• Peer leaders can be highly effective in delivering substance abuse prevention programs.
• The program shows promise for preventing multiple forms of adolescent substance abuse.
