Although the heavy episodic drinking (HED) measure of 5+ drinks (sometimes 4+ for women) is used extensively, there is no empirical basis for the designation of 5 drinks as the threshold (vs. another threshold that may perform equally). The present study sought to determine the threshold for HED that maximally predicts proximal and distal adverse-drinking-related outcomes. Participants included 115 young adults (57% female; 96% Caucasian) who partook in an 8-week Internet survey that assessed daily drinking as well as next-day hangover; 10 months later, adverse outcomes (problem drinking, alcohol-related problems, maximum number of drinks, and drug use) were surveyed. Thresholds were computed, with a range from 1+ drinks to 15+ drinks, and outcomes were predicted from each threshold. Findings for hangover measures showed relatively good convergence across multiple indicators, with greatest prediction occurring at a threshold of 10+ drinks per occasion. Different thresholds were observed for long-term outcomes, with higher thresholds indicative of outcomes with greater severity. Although alternatives to HED, such as subjective effects and blood alcohol concentration, can indicate risky drinking, a threshold measure of HED may have advantages in terms of prevention and of intervention efforts.
尽管大量饮酒（HED）的衡量标准为一次饮用5杯及以上（女性有时为4杯及以上）被广泛使用，但将5杯定为阈值（相对于可能同样有效的另一个阈值）并无实证依据。本研究旨在确定能最大程度预测近期和远期与饮酒相关不良后果的大量饮酒阈值。参与者包括115名年轻人（57%为女性；96%为白种人），他们参与了一项为期8周的网络调查，该调查评估每日饮酒情况以及次日的宿醉情况；10个月后，对不良后果（问题饮酒、与酒精相关的问题、最大饮酒量和药物使用）进行了调查。计算了从1杯及以上到15杯及以上的阈值，并根据每个阈值预测结果。宿醉测量结果显示，多个指标之间的收敛性相对较好，每次饮用10杯及以上时预测效果最佳。长期结果观察到不同的阈值，阈值越高表明结果越严重。尽管除大量饮酒外的其他指标，如主观感受和血液酒精浓度，也能表明危险饮酒，但大量饮酒的阈值测量在预防和干预方面可能具有优势。
