Preventing Adolescent Substance Use: A Content Analysis of Peer Processes Targeted Within Universal School-Based...

Area of Science:

• Public Health
• Psychology
• Sociology

Background:

• Universal school-based substance use prevention programs are common.
• Peer relationships are a key focus in these programs.
• Network theory and social network analysis (SNA) offer frameworks for studying peer influence.

Purpose of the Study:

• To systematically analyze the peer processes targeted by universal school-based substance use prevention programs.
• To evaluate the extent to which programs address different levels of peer influence (dyadic, subgroup, network).
• To inform future intervention research by identifying areas of focus and potential malleability of peer processes.

Main Methods:

• Content analysis was used to systematically code peer processes in three universal school-based prevention programs.
• Peer processes were categorized by type (socialization vs. selection), norms (descriptive vs. injunctive), valence (positive vs. negative), and level (dyadic, subgroup, network).

Main Results:

• Programs predominantly focused on peer socialization over selection and equally on descriptive and injunctive norms.
• Most references to peer processes highlighted positive processes and negative behaviors.
• Network-level processes received the most attention, though typically for less than 50% of lesson content.
• Discussion and reflection were common when peer processes were addressed.

Conclusions:

• Current universal prevention programs emphasize peer socialization and network dynamics.
• There is a discrepancy between program focus and non-intervention research highlighting dyad-level and selection processes.
• The findings provide a framework for evaluating program content and guiding future research on malleable peer processes in adolescent substance use prevention.
