The purpose of this study was to assess the relationship between level of intoxication and the frequency and severity of aggression at the person, incident, visit, and bar level for aggressive incidents observed in bars or clubs.
Hierarchical Linear Modeling (HLM) analysis of 1025 incidents of aggression documented by trained observers during 1334 nights of observation in 118 bars and clubs in Toronto, Canada, was conducted.
Both level of intoxication of the crowd during the visit as well as mean level of intoxication at the bar level significantly predicted frequency of aggression. There was a positive association between level of intoxication and severity of aggression at both the incident and person level except for the highest level of intoxication at the person level, where severity of aggression was less than for moderate intoxication. A person-incident level interaction between intoxication and severity of aggression was also found.
These results suggest that prevention efforts should focus on both identifying bars that typically have more intoxicated patrons and reducing the intoxication levels of patrons across bars generally. The results also showed a strong positive relationship between level of intoxication and severity of aggression (except at the highest levels), indicating that intoxication increases risk in terms of both frequency and severity of aggression. The significant interaction between person- and visit-level intoxication suggests that greater attention needs to be paid to group dynamics in alcohol-related aggression.
本研究旨在评估在酒吧或俱乐部中观察到的攻击事件中，醉酒程度与个人、事件、到访及酒吧层面攻击行为的频率和严重程度之间的关系。
对加拿大多伦多118家酒吧和俱乐部在1334个夜晚的观察期间，由训练有素的观察员记录的1025起攻击事件进行分层线性模型（HLM）分析。
到访期间人群的醉酒程度以及酒吧层面的平均醉酒程度均能显著预测攻击频率。在事件和个人层面，除了个人层面醉酒程度最高时攻击严重程度低于中度醉酒情况外，醉酒程度与攻击严重程度之间存在正相关。还发现了醉酒程度与攻击严重程度之间的个人-事件层面交互作用。
这些结果表明，预防措施应侧重于识别通常有更多醉酒顾客的酒吧，并普遍降低各酒吧顾客的醉酒程度。结果还显示，醉酒程度与攻击严重程度之间存在很强的正相关（最高水平除外），表明醉酒会增加攻击行为的频率和严重程度方面的风险。个人层面和到访层面醉酒之间的显著交互作用表明，在与酒精相关的攻击行为中，需要更加关注群体动态。
