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 11 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.
现有的关于区分适度饮酒与持续饮酒的年轻成年人的发展研究，并未始终如一地评估所建模的酒精摄入领域，这使得跨研究比较结果变得困难。在本研究中，作者使用377名年轻成年人的前瞻性（6波次）样本（第1年年龄 = 18.52岁；55%为女性；51%有酗酒家族史），对11年间酒精摄入的5个指标的发展过程进行了描述。对每个测量指标应用了生长混合模型。尽管轨迹形状相似，但预测患病率各不相同，并且跨替代指标的轨迹分类一致性显示出低一致性。然而，饮酒过程的相关因素在不同酒精指标之间在一定程度上是稳健的。轨迹取决于所使用的特定指标这一发现表明，跨酒精摄入的替代指标进行概括可能是有风险的。
