Samenvatting

In this article, the authors summarize some important methodological problems that may be encountered when studying the crime preventative effects of restorative justice. Studies mostly focus on tertiary preventative effects, namely the reduction of recidivism. Empirical research is in that regard mainly dealing with the effects of victim-offender mediation and conferencing practices. Some problems include the definitional issue (what can be considered as a restorative justice intervention?), the (quasi-)experimental design, the small size of samples and issues of comparability between different studies due to differences in e.g. follow-period or criteria for measuring recidivism.
