Higher bar density correlates with increased alcohol-related aggression norms and hostility, suggesting a link between drinking environments and aggressive behaviors. This impacts social contexts where people drink.
Area of Science:
- Sociology
- Criminology
- Public Health
Background:
- Observed statistical relationships between bar/pub densities and violence rates.
- Two theoretical approaches: social influence and social selection.
Purpose of the Study:
- Examine statistical relationships between bar/pub densities and violence rates.
- Investigate social influence and social selection theories.
Main Methods:
- Stratified sample of 36 California zip codes (high, medium, low bar density).
- Used US Census 2000 data for demographics.
- Conducted telephone surveys on demographics, drinking patterns, hostility, and aggression norms.
- Employed hierarchical linear models to assess relationships.
Main Results:
- Higher bar density linked to lower aggression norms, higher alcohol-related aggression norms.
- Greater peak drinking levels correlated with increased hostility and aggression norms.
- Hostility and alcohol-related aggression norms associated with drinking at bars, parties, and homes.
- Aggressive norms linked to drinking at parties.
Conclusions:
- Findings indicate relationships between alcohol outlet densities and social-psychological violence correlates.
- These factors are associated with social drinking contexts.
- The interplay between aggressive individuals and environments warrants further investigation.
