Antecedent variables under the broad categories of genetic, environmental and cultural influences have been linked to the risk for alcohol abuse. Such risk factors have not been shown to result in high correlations with alcohol consumption and leave unclear an understanding of the mechanism by which these variables lead to increased risk. This study employed covariance structure modeling to examine the mediational influence of stored information in memory about alcohol, alcohol expectancies in relation to two biologically and environmentally driven antecedent variables, family history of alcohol abuse and a sensation-seeking temperament in a college population. We also examined the effect of criterion contamination on the relationship between sensation-seeking and alcohol consumption. Results indicated that alcohol expectancy acts as a significant, partial mediator of the relationship between sensation-seeking and consumption, that family history of alcohol abuse is not related to drinking outcome and that overlap in items on sensation-seeking and alcohol consumption measures may falsely inflate their relationship.
在遗传、环境和文化影响这几大类广泛范畴下的先行变量已被认为与酒精滥用风险相关。然而，这些风险因素与酒精消费之间并未显示出高度相关性，并且对于这些变量导致风险增加的机制尚不清楚。本研究采用协方差结构建模，以检验在大学生群体中，关于酒精的记忆存储信息、与两个由生物和环境驱动的先行变量（酒精滥用家族史和寻求刺激的气质）相关的酒精期望的中介影响。我们还检验了标准污染对寻求刺激与酒精消费之间关系的影响。结果表明，酒精期望是寻求刺激与消费之间关系的一个显著的部分中介变量，酒精滥用家族史与饮酒结果无关，并且寻求刺激和酒精消费测量项目上的重叠可能会错误地夸大它们之间的关系。
