The role of peers in delinquent behaviour of adolescents

The aim of this study is to get more insight into the role of peers in the development of problem- and delinquent behaviour in adolescents. Data are derived from the longitudinal NSCR Schoolproject, in which secondary school students were surveyd repeatedly (2002-2004). The questionnaire of this study asked participants to nominate friends from a list of all fellow students from the same grade level (the ones with whom they associate with and the ones with whom they associate the most). This method enabled to relate the development of social networks of secondary school students with the development of delinquent and problem behaviour.

The data makes it possible to measure directly to which extent respondents are friends with delinquent fellow students, which can be compared to traditional measurements in which adolescents are asked about the perceived delinquency of their friends. Further, longitudinal network data can lead to more insight in the existence of influence processes (delinquent friends lead to more delinquent behaviour) and.or selection processes (delinquent adolescents tend to become friends with delinquent others).

In 2009 the dataset is augmented with information about the neighborhoods of a part of the respondents of the schoolproject, which enables to distinguish contextual effects of the neighborhood with contextual effects of the networks and school classes. This project entails collaboration with international investigators in the area of peers and juvenile delinquency.

About prof. dr. Frank Weerman


Frank Weerman received his Masters degree in Sociology in 1992, with a specialisation in Criminology. In 1998, he received his PhD at the University of Groningen, for which he conducted an empirical study to test and expand Hirschi’s social control theory on juvenile delinquency. From 1998 until 2000, Weerman was affiliated as a postdoc researcher at the University of Twente, where he wrote a book about co-offending, criminal cooperation and group formation. He is affiliated with the NSCR since August 2000, currently in the position of senior researcher. His research interests are juvenile delinquency and criminological theory, with a focus on the role of peers in delinquent behaviour. Since 2002, he coordinated the “School Project”, a longitudinal study among secondary school students that included datacollection on changes in delinquency and social networks among the students. Under the umbrella of the international research network “Eurogang”, he published on troublesome youth groups and gangs. Since 2008, he is involved in the longitudinal Study of Peers, Activities and Neighbourhoods (SPAN).

Frank is a member of the Life-course Cluster, the Intergenerational Cluster, the Cybercrime Cluster and the Extremism/Terrorism Cluster.
