A 3-wave longitudinal design was used to examine the relationships among emotional restraint, peer drug associations, and gateway drug use in a sample of 1,256 middle school students. Structural equation modeling was used to compare 3 models: (a) One model viewed drug use as a consequence of emotional restraint and peer variables; (b) 1 viewed drug use as a cause of restraint and peer variables, and (c) 1 included reciprocal effects. All 3 models fit the data fairly well. However, the reciprocal model fit the data significantly better than either of the others. Within this model, low emotional restraint was significantly related to subsequent increases in gateway drug use among boys. In contrast, peer drug models and peer pressure were not related to subsequent changes in gateway drug use. Changes in peer drug models were, however, predicted by previous levels of gateway drug use.
采用三波纵向设计，在1256名中学生样本中检验情绪抑制、同伴药物关联和入门药物使用之间的关系。使用结构方程模型比较了三个模型：(a) 一个模型将药物使用视为情绪抑制和同伴变量的结果；(b) 一个模型将药物使用视为抑制和同伴变量的原因，以及 (c) 一个模型包括相互影响。所有三个模型都与数据拟合得相当好。然而，相互模型对数据的拟合明显优于其他任何一个模型。在这个模型中，低情绪抑制与男孩随后入门药物使用的增加显著相关。相比之下，同伴药物模型和同伴压力与随后入门药物使用的变化无关。然而，同伴药物模型的变化是由先前的入门药物使用水平预测的。
