Samenvatting

This article investigates whether cyber delinquent behaviour of school friends, other offline friends and online contacts is related to cyber delinquent behaviour of individuals, and whether this relation differs for cyber dependent, cyber enabled and traditional crime. We used both direct and indirect measures of cyber delinquency of friends. We employed data from the first wave of a large-scale study on the causes of online delinquency among Dutch juveniles (n=889; mean age=16.8 years). The results suggest that both direct and indirect measures of levels of friend delinquency were related to levels of individual cyber offending. However, indirect measures had a stronger association with individual online delinquency than direct measures. This suggests that respondents make incorrect estimates of their friends’ levels of online delinquency. Moreover, no differences were found in the strength of the relation between individual online offending and indirect measures of online offending of school friends, offline friends and online friends. This suggests that friends of different types all play an important role in individual online offending.
