作者研究了同伴网络的特性如何影响洛杉矶(n=217；3个月时保留83%；墨尔本(n=119；3个月时保留72%)的12至20岁新无家可归青少年在3个月内的苯丙胺、可卡因和注射毒品的使用。提出了几个关于社会网络属性对同伴影响过程的影响的假设。多因素Logistic回归分析表明，在招募时，网络中无家可归的同龄人密度较高，与3个月后使用安非他明和可卡因的可能性增加有关。注射同龄人浓度较高与3个月后注射毒品的风险增加相关，网络结构随时间的变化朝着无家可归同龄人密度的增加与可卡因使用和注射的风险增加相关。基线密度较高的网络与3个月后使用可卡因和苯丙胺的可能性增加呈正相关。
The authors examine how the properties of peer networks affect amphetamine, cocaine, and injection drug use over 3 months among newly homeless adolescents, aged 12 to 20 in Los Angeles (n = 217; 83% retention at 3 months) and Melbourne (n = 119; 72% retention at 3 months). Several hypotheses regarding the effects of social network properties on the peer influence process are developed. Multivariate logistic regression analyses show that higher concentrations of homeless peers in networks at recruitment were associated with increased likelihood of amphetamine and cocaine use at 3-month follow-up. Higher concentrations of injecting peers were associated with increased risk of injection drug use 3 months later Change in network structure over time toward increased concentrations of homeless peers was associated with increased risk of cocaine use and injecting. Higher density networks at baseline were positively associated with increased likelihood of cocaine and amphetamine use at 3 months.
