The main objective of this study was to measure the alcohol content in college party drinks. Samples of mixed drinks were collected from on-campus parties (N = 23) over a 12-week period at a university in the Northeast. Samples were analyzed by using a method that measures oxygen utilization during ethanol oxidation. Standard drink equivalents were calculated and blood alcohol concentrations (BACs) for men and women were estimated. The percent alcohol in sampled drinks ranged from 3.7% to 22.8%. Characteristics of the sampled parties were not related to drink concentration. A party drink at the median concentration and drink size contained 0.97 standard drinks. Estimated BACs varied widely depending on drink alcohol concentration, but in most cases a heavy drinking episode for both men and women resulted in an estimated BAC at or above .08. Mixed drinks at the sampled parties on average approximated one standard drink, but the variability in mixed drink strength compromises a drinker's ability to keep track of the number of drinks consumed.

本研究的主要目的是测量大学派对饮品中的酒精含量。在东北部一所大学为期12周的时间里，从校园派对上收集了混合饮品样本（N = 23）。通过一种测量乙醇氧化过程中氧气利用情况的方法对样本进行分析。计算了标准饮品当量，并估算了男性和女性的血液酒精浓度（BAC）。所采集饮品中的酒精含量在3.7%至22.8%之间。所采集派对的特征与饮品浓度无关。处于中位数浓度和饮品量的一杯派对饮品含有0.97个标准饮品。估算的BAC因饮品酒精浓度不同而差异很大，但在大多数情况下，男性和女性的一次重度饮酒都会导致估算的BAC达到或超过0.08。所采集派对上的混合饮品平均约为一个标准饮品，但混合饮品强度的变异性会影响饮酒者记录所饮用量的能力。（《心理学文摘数据库记录》（c）2009美国心理学会，保留所有权利）
