Peer and adolescent substance use are highly correlated, but this relationship is not fully understood. In particular, the relative contributions of selection and socialization to substance use progression have not been established. Students (n=2453) in the seven middle schools in one school district were assessed at school at the beginning and end of the sixth, seventh, eighth grade and beginning of the 9th grade. Self-reported smoking and drinking and the number of substance using friends were assessed 5 times over 3 years. The relationship between peer and adolescent substance use were assessed in parallel processes as part of an autoregressive latent trajectory model. Substance use and the number of substance using friends increased in linear fashion from T1 to T5. Initial substance use predicted an increase in the number of substance using friends over time, indicating an effect of selection, and the initial number of substance using friends predicted substance use progression, providing evidence of socialization. The magnitudes of these relationships were similar. Bivariate, lagged autoregressive analyses of the successive relationships from one assessment to the next showed consistent, significant associations from peer use to adolescent substance use. The association from adolescent to peer use was significant only from 7th to 8th grade. The findings provide evidence of reciprocal influences, but socialization was a more consistent influence than selection.
同伴和青少年的物质使用高度相关，但这种关系尚未完全明晰。特别是，选择和社会化对物质使用进展的相对贡献尚未确定。对一个学区七所中学的学生（n = 2453）在六年级、七年级、八年级末以及九年级初进行了校内评估。在三年时间里对自我报告的吸烟、饮酒情况以及有物质使用行为的朋友数量进行了5次评估。作为自回归潜在轨迹模型的一部分，在平行过程中评估了同伴和青少年物质使用之间的关系。从T1到T5，物质使用和有物质使用行为的朋友数量呈线性增加。初始物质使用预示着随着时间推移有物质使用行为的朋友数量会增加，这表明了选择的影响，而有物质使用行为的朋友的初始数量预示着物质使用的进展，这为社会化提供了证据。这些关系的强度相似。对从一次评估到下一次评估的连续关系进行的双变量滞后自回归分析显示，从同伴使用到青少年物质使用存在一致且显著的关联。从青少年到同伴使用的关联仅在七年级到八年级时显著。研究结果提供了相互影响的证据，但社会化的影响比选择更为一致。
