This article combines the qualitative tradition of naturalistic observations with quantitative multivariate methods to quantify the relationships between drinker characteristics, group composition, duration of the drinking period and alcohol consumption. Employing observational data on over 6,000 drinkers collected in six on-premise licensed establishments in California, structural equation regression methods were used to estimate the simultaneous effects of duration of the drinking period and total consumption on each other, controlling for patron characteristics and group composition. Results from all six establishments indicate that consumption is higher in larger groups because of longer drinking times at the establishment and not because of any direct effect of consumption on length of the drinking period. Group composition effects on consumption are also indicated since females in mixed drinking groups tend to reduce the alcohol consumption of males, but not the group as a whole.
本文将自然主义观察的定性传统与定量多变量方法相结合，以量化饮酒者特征、群体构成、饮酒时间段时长与酒精消费量之间的关系。利用在加利福尼亚州六家有酒类销售许可证的营业场所收集的6000多名饮酒者的观察数据，采用结构方程回归方法来估计饮酒时间段时长和总消费量对彼此的同时影响，并控制顾客特征和群体构成。所有六家营业场所的结果表明，在较大群体中消费量较高是因为在营业场所的饮酒时间较长，而不是因为消费量对饮酒时间段时长有任何直接影响。群体构成对消费量的影响也得到了体现，因为在混合饮酒群体中，女性往往会降低男性的酒精消费量，但不会降低整个群体的酒精消费量。
