The increasing prevalence of multiple drug use among adolescents presents researchers with complex conceptual and measurement issues. This work examines definitions of and indicators of multiple drug use involvement, as well as the interrelationships between indices of drug involvement incorporating different dimensions. Data regarding the relationship between patterns of alcohol use and illicit drug use in a population of 1473 teenagers interviewed in a northwestern metropolitan community indicate that : (1) regardless of the dimensions incorporated into four different indices of drug involvement examined, intercorrelations between indices were strong; (2) although the correlations between indices of drug involvement and overall levels of alcohol intake were uniformly weak, it was shown that levels of drug involvement vary directly with the maximum volume of alcohol used. Although the results of the current investigation must be viewed cautiously because of the concentration of heavy users of both alcohol and drugs in the population upon which the research is based, among adolescents, the spacing of drinking episodes and the patterning of alcohol intake may be more important determinants of polydrug involvement thant the quantity of alcohol consumed.
青少年中多药使用的日益普遍给研究人员带来了复杂的概念和测量问题。这项工作研究了多药使用参与的定义和指标，以及纳入不同维度的药物参与指数之间的相互关系。在一个西北大都市社区对1473名青少年进行访谈的数据显示了酒精使用模式与非法药物使用之间的关系，结果表明：（1）无论纳入所考察的四种不同药物参与指数的维度如何，各指数之间的相互关联都很强；（2）虽然药物参与指数与酒精摄入总量之间的相关性始终较弱，但研究表明，药物参与程度与酒精使用的最大量直接相关。尽管由于该研究基于的人群中酒精和药物的重度使用者较为集中，当前调查结果必须谨慎看待，但在青少年中，饮酒发作的间隔和酒精摄入模式可能比饮酒量更重要，是多药使用参与的决定因素。
