At the level of local government, preventive and repressive measures are used within an integrated- personalized-approach to prevent disturbing and criminal behaviour. This integrated approach is only possible when the professionals involved can share data of subjects in order to get good insight of the existing problems and to find possible solutions. The Startbaan study, which focused on the collaboration within such an integrated-approach on young adults with multiproblems and justice contacts, shows that privacy regulations are perceived as being obstructive by professionals. More knowledge about the GDPR, its legal bases and domain specific regulations is necessary for an integrated-approach.

Prison visitation is important for protecting against social isolation during imprisonment. It is also essential for maintaining contacts that are important for life in prison and after release. It is therefore not surprising that both nationally and internationally important policy measures and scientific research have been undertaken on the topic. Nationally, however, limited scientific research is available regarding how many, how often and from whom prisoners receive visits, how visits are experienced and the possible effects of visitation, thus leaving many questions unanswered. Meanwhile, in the past ten years great changes have been made to visitation in Dutch prison policy and practice. Given these recent developments, both scientists and practitioners could benefit from an overview of the current state of affairs of visitation. This article aims to bridge the gap between research, policy and practice by summarizing findings from the Life in Custody study. This study includes a description of how visitation is organized legally, at the policy level and in practice, a thorough review of prior research on visitation and an analysis of the most recent national data on the prevalence and frequency of visitation, while considering important differences between prisoners and prisons.
