title: Effects of the Campus Watch intervention on alcohol consumption and related harm in a university population.
abstract: BACKGROUND
  High levels of drinking and alcohol-related problems are pervasive among university students in New Zealand and other high-income countries, where controls on alcohol availability and promotion are typically weak. Environmental interventions to reduce hazardous drinking and harm have shown promise in general populations, but require further evidence of effectiveness in university settings. The aim of this study was to estimate the effect of a community liaison and security program, Campus Watch, on drinking patterns and alcohol-related harm among university students.
  
  
  METHODS
  The study used a quasi-experimental design with non-equivalent control sites using before (2005) and after (2009) observations. Participants were full-time students aged 17-25 years selected randomly from the enrolment lists of six New Zealand universities. Changes in scores on the alcohol use disorders identification consumption scale (AUDIT-C) and alcohol-related harms at the intervention campus were compared with those at control campuses using linear and logistic regression models.
  
  
  RESULTS
  Compared to control campuses, AUDIT-C scores decreased in students at the intervention campus (β=-0.5, 95% CI: -0.6 to -0.3). Campus Watch was associated with reductions in some harms (independent of its effect on drinking), such as aggression (aOR 0.66, 95% CI: 0.46 to 0.94), but not other harms, e.g., blackouts (aOR 1.06, 95% CI: 0.89 to 1.27).
  
  
  CONCLUSIONS
  While not being focused on alcohol per se, Campus Watch reduced alcohol consumption and some related harms. Such programs may be useful in similar environments where controls on alcohol availability and promotion cannot be affected and where informal controls are weak.
