现有的发展研究区分了适度饮酒和持续饮酒的年轻人，并没有一致地评估酒精涉及的领域，因此很难比较不同研究的结果。在本研究中，作者对377名年轻成人（第一年年龄18.52岁，55%为女性，51%有酗酒家族史）进行了前瞻性（6波）研究，描述了5项酒精相关指标的发展历程。生长混合模型应用于每个测量。尽管轨迹形状相似，但预测的患病率各不相同，而且不同指标之间轨迹分类的一致性显示一致性较低。然而，饮酒过程的相关性在整个酒精指数中都有所增强。研究发现，轨迹取决于所使用的具体指标，这表明，将酒精参与的其他指标一概而论可能是危险的。
Extant developmental research distinguishing young adults who moderate versus persist in alcohol consumption has not consistently evaluated the domain of alcohol involvement being modeled, making it difficult to compare findings across studies. In the present study, the authors characterized the developmental course of 5 indices of alcohol involvement using a prospective (6-wave) sample of 377 young adults (Year 1 age = 18.52 years; 55% female; 51% with family history of alcoholism) over I I years. Growth mixture models were applied to each measure. Despite similarity in trajectory shape, predicted prevalences varied, and the consistency of trajectory classifications across alternate indices revealed low agreement. Correlates of drinking course, however, were somewhat robust across alcohol index. The finding that trajectories are conditional on the specific indices used suggests that it may be hazardous to generalize across alternate indices of alcohol involvement.
