ABSTRACT
A central aim for research on antisocial behaviour should be to produce knowledge that can be used to develop and implement effective interventions for people exhibiting antisocial behaviour. For a practitioner seeing a client with a history of antisocial behaviour the task is to find a way to approach the client to achieve a positive change in behaviour. As the practitioner turns to empirical evidence to find the most important aspects to take into account and focus on in this task, would there be sufficient knowledge to provide guidance? In many cases, we would argue that the answer is likely to be no. There are aspects of antisocial behaviour that are either under-researched or not teased apart in a satisfactory way, partly due to the fact that much of existing empirical knowledge has not addressed the heterogeneity among individuals with antisocial behaviour.
