同龄群研究的重要性本文的目的是强调在理论和方法论基础上进行纵向研究(尤其是同龄群研究)的重要性。在犯罪学领域进行纵向研究并非创举。谢尔登·格卢克和埃莉诺·格卢克首倡对麻省教养院开释的一群同龄人的跟踪研究;这两位学者进行了三次每次为期五年的跟踪研究,并追查了惯犯的案卷。再如:麦科德一直在继续研究早先的剑桥萨默维尔青少年犯罪课题;李·罗宾斯跟踪研究过一群已长大成人的行为异常儿童。但这些都不是同龄群。这些罪犯都是长大成人后在不同的年龄上被收集在一起的。一个同龄群则是指在同一年里出生的人,并对他们生 The Importance of Peer Study The purpose of this article is to emphasize the importance of longitudinal research (especially peer group research) based on theory and methodology. Longitudinal research in the field of criminology is not a pioneering one. Sheldon Grücker and Eleanor Gluck pioneered a follow-up study of a group of peers who were released at the Massachusetts Correctional Institution; the two scholars conducted three three-yearly follow-up studies and tracked down recidivists The case file Another example: McCord has been continuing to study the earlier issue of juvenile delinquency in Somerville, Cambridge; Lee Robbins tracked a group of grown-up children with abnormal behavior.

One peer group refers to people who were born in the same year and gave birth to them
