最近使用项目反应模型的调查已经开始将酒精消费、问题和依赖概念化，作为酒精参与的单一连续体的代表点。这种概念化可能对测量青少年的酒精参与特别有益，但迄今为止的调查仅限于成人样本，由于与年龄有关的发育差异，可能无法推广到青少年。本研究使用Rasch模型分析，在Add Health调查的第1波中，对6,353名年龄在12至18岁的青少年的酒精消费指数和问题进行了检查。特别关注的是，当这些青少年在18至24岁时在第三波中再次接受采访时，这些物品的功能是否发生了变化。Rasch模型分析支持Wave 1数据中项目的单维性和可加性。波1和波3数据的比较表明，在大多数项目中，与酒精消费相关的项目在青春期更严重，而与酒精问题相关的项目在青年期更严重。结合酒精消费指数和酒精问题指数，可以构建有效的青少年酒精卷入指数。该指数涵盖了不同性别和种族/民族的一系列严重程度和功能。一个类似的指数可以建立在年轻的成年期。然而，分数的解释必须注意到发展差异。特别是对青少年来说，酒精消费指数在严重程度上比年轻人更接近酒精问题指数。因此，在饮酒水平相似的情况下，青少年比年轻人更容易出现酒精问题。
Recent investigations using item response modeling have begun to conceptualize alcohol consumption, problems, and dependence as representing points along a single continuum of alcohol involvement. Such a conceptualization may be of particular benefit to measurement of alcohol involvement in adolescents, but investigations to date have been limited to adult samples and may not generalize to adolescents due to age-related developmental differences.This study used Rasch model analyses to examine the properties of indices of alcohol consumption and problems among 6,353 adolescents, aged 12 to 18 years, in Wave 1 of the Add Health survey. A particular focus was on whether the functioning of items changed when these adolescents were re-interviewed in Wave 3 when they were 18 to 24 years of age.Rasch model analyses supported the unidimensionality and additive properties of the items in the Wave 1 data. Comparisons of Wave 1 and Wave 3 data indicated differential item functioning in most of the items such that items related to alcohol consumption were more severe during adolescence, whereas items related to alcohol problems were more severe in young adulthood.A valid index of alcohol involvement in adolescents can be constructed combining indices of alcohol consumption and alcohol problems. Such an index covers a range of severity and functions similarly across sex and race/ethnicity. A similar index can be constructed in young adulthood. However, the interpretation of scores must be attentive to developmental differences. In particular, for adolescents, indices of alcohol consumption are relatively closer in severity to indices of alcohol problems than they are among young adults. Thus, alcohol problems are more likely among adolescents than young adults given a similar level of drinking.
