Computer-Based Prevention and Intervention to Reduce Substance Use in Youth

Area of Science:

• Digital Health
• Adolescent Psychology
• Public Health Interventions

Background:

• Technology-driven programs are increasingly used for youth substance use prevention and intervention.
• These digital tools align with how young people interact with information and their environment.
• Recent evidence focuses on computer-based delivery methods, including tablets and smartphones.

Purpose of the Study:

• To review recent evidence on computer-based programs for youth substance use.
• To specifically examine results from randomized controlled trials.
• To assess the effectiveness and limitations of technology-driven interventions.

Main Methods:

• Systematic review of outcome studies published in the last five years.
• Focus on randomized trials examining computer-based substance use programs for youth.
• Analysis of intervention approaches, delivery settings, and study quality.

Main Results:

• Outcome studies show mixed results, with diverse intervention strategies and settings.
• High attrition rates are a common limitation across many studies.
• International programs are prevalent, but often lack customization for specific populations.
• High-quality studies, though few, indicate positive outcomes in reducing substance use.

Conclusions:

• Computer-delivered interventions require further development to be considered a proven method for youth substance use reduction.
• There is a need for original programs specifically designed for distinct youth subgroups.
• Despite the increasing use of controlled designs, study flaws like high attrition limit the conclusive discovery of positive outcomes.
