In this introductory chapter we provide an overview of criminological research into intergenerational transmission of criminal behaviour that currently is, and has been, conducted both internationally and in the Netherlands. The most important findings of these studies are also discussed. Next, possible explanations are discussed for intergenerational transmission of crime in general, and more particularly for families that are involved in more serious and organized crime. Moreover, possible ways in which intergenerational transmission of crime can be prevented are discussed. Finally, we give some directions for future research on this topic and will introduce the contributions to this special issue.

In criminology, explanations for engagement in externalizing or criminal behavior are often found within the direct (social) environment of the individual. More specifically, family functioning, the quality of family relations and parenting strategies during childhood and adolescence are found to be related to the development of externalizing problems or criminal behavior over the life-course. Although less well studied, the opposite might also be true: externalizing problems or delinquency during childhood and adolescence may in turn also affect some important (family-related) transitions over the life-course, such as engagement in romantic relationships, the transition to parenthood, parenting strategies and broader family functioning. Not surprisingly, in life-course criminology there is increasing attention for familial similarities in externalizing and delinquent behavior. What underlies intergenerational continuity of criminal behavior? Under which circumstances behavior is continued over the course of generations? What is the role of the family? What is needed to break intergenerational cycles and facilitate earlier and more effective interventions? In this article, a literature review is provided on the role of the family in intergenerational continuity of externalizing or criminal behavior over the life-course and across generations.

In the present study, the role of genetic and cultural transmission in intergenerational continuity of rule-breaking behavior (RBB) was investigated. Based on the resemblance within 3,982 Dutch twin pairs, aged 13 to 17 years, the relative importance of genetic (G), shared environmental (C), and unique environmental (E) influences on RBB was estimated. Cultural transmission, the process of passing on knowledge, norms and values, can lead to similarities within families, and forms part of the shared environment of children growing up in the same family. The authors found no evidence for shared environmental influences, and consequently no indication of a role for cultural transmission. Genetic influences explained 60 percent of the variance in rule-breaking behavior at age 13 to 17, implying that intergenerational continuity at this age is mainly driven by genetic transmission.

This study (N=921) examines whether living together with a criminal parent moderates the intergenerational continuity of crime. Results are mixed, but show that the intergenerational continuity of crime decreases when the child lived together with the criminal parent for a shorter period of time. This association is most strong for children whose criminal mothers live on a large distance from them. Longitudinal fixed effects models, however, show that these results are likely the consequence of between-individual differences and therefore do not reflect causal influences on the intergenerational continuity of crime.

Previous research on intergenerational continuity of crime is primarily focused on transmission from fathers to children. In this article, we aim to give insight in the role of mothers in (the prevention of) continuity of organized crime. The results of our explorative study on 25 organized crime offenders based in Amsterdam and their partners and children, show that parenting skills and norms and values of mother seem to have an important role in both the intergenerational continuity of organized crime and the prevention of the transmission.

In The Netherlands not much attention has been paid towards the relationship between domestic violence and organized crime. In this contribution the question is addressed why this is. One of the answers is that there is doubt about the moral status of the victim of organized crime: it assumed that the victim has benefited from the proceedings of organized crime. When domestic violence and involvement with organized crime by one of the family members come together, the case becomes more complex and difficult to deal with. For that reason professionals and researchers should pay more attention to the overlap of both phenomena.
