Peer influence and selection significantly impact adolescent drinking behavior. This meta-analysis confirms positive peer influence and selection effects, highlighting the need for targeted prevention programs.
Area of Science:
- Social Sciences
- Psychology
- Public Health
Background:
- Adolescent drinking behavior is influenced by social dynamics.
- Distinguishing peer influence from peer selection is crucial for understanding these dynamics.
Purpose of the Study:
- To quantitatively assess the effects of peer influence and peer selection on adolescent drinking.
- To provide a rigorous statistical synthesis of existing research.
Main Methods:
- Systematic literature search for longitudinal network studies on adolescent drinking.
- Meta-analysis of parameter estimates using multilevel random-effects models.
- Stochastic actor-oriented modeling (SAOM) was employed in eligible studies.
Main Results:
- 26 articles were included in the meta-analysis.
- Positive peer influence effects were found across all specifications (avSim, totSim, avAlt).
- A significant positive peer selection effect (simX) was also identified, with medium to large effect sizes (Cohen's d: 0.25–0.70).
Conclusions:
- Methodological advancements enable accurate estimation of peer influence, distinct from selection effects.
- Further research is needed on moderating factors like age and gender.
- Findings can inform the development of effective adolescent alcohol prevention strategies.
