[Prevention of substance use disorders]

Area of Science:

• Public Health
• Adolescent Psychology
• Behavioral Science

Background:

• Adolescence presents a critical window for the onset of substance use disorders (SUDs).
• Preventive interventions for SUDs are a significant public health concern.
• Evidence for behavioral prevention strategies in adolescents is growing.

Purpose of the Study:

• To summarize existing evidence on behavioral preventive interventions for adolescent SUDs.
• To analyze the effectiveness of prevention strategies across various settings.
• To identify gaps and future directions in adolescent SUD prevention research.

Main Methods:

• Meta-analytic review of studies on adolescent substance use prevention.
• Analysis of interventions in school, family, and internet-based settings.
• Examination of differential effectiveness based on age and intervention type.

Main Results:

• Developmentally sensitive substance use prevention is effective across settings, yielding small-to-middle effects.
• Universal school-based prevention benefits younger adolescents most.
• Targeted approaches are more effective for older adolescents; internet-based prevention shows promise.
• The majority of studies originate from the US, with limited research from Germany.

Conclusions:

• Effective preventive measures for adolescent SUDs exist across multiple settings.
• Improvements are possible through translational research focusing on individualized and tailored approaches.
• Further research is needed on program implementation, differential intervention module effects, and coordinated community-level strategies, especially in Germany.
