Alcohol expectancies are an important proximal causal risk factor in several models of the familial transmission of alcohol use, abuse, and dependence, yet the familial transmission of alcohol expectancies is not well understood. The purpose of this study was to examine the familial transmission of positive alcohol expectancies. Participants were 2,627 14- to 22-year-old female twins. Experiences shared by twins, rather than genetic factors, explained most of the familial similarity for positive alcohol expectancies, but an even larger proportion of the variation in positive alcohol expectancies was explained by nonfamilial factors. The extent to which the familial similarity for positive alcohol expectancies was moderated by age, race, drinking status, and the sharing of peer groups was also examined.
在酒精使用、滥用和依赖的家族传播的几种模型中，对酒精的预期是一个重要的近端因果风险因素，然而，人们对酒精预期的家族传播却了解甚少。本研究的目的是检验积极酒精预期的家族传播情况。研究对象为2627名14至22岁的女性双胞胎。双胞胎共同的经历，而非遗传因素，解释了积极酒精预期的大部分家族相似性，但积极酒精预期变异的更大比例是由非家族因素解释的。研究还考察了年龄、种族、饮酒状况和同伴群体共享对积极酒精预期家族相似性的调节程度。
