Although reward systems are utilized in prisons worldwide, evaluations regarding their intended use are lacking. This contribution reconstructs the policy theory of such a system: Promotion and Demotion, as implemented in Dutch prisons in 2014. With a policy scientific approach the intended target group, means, goals and causal mechanisms of the system were delineated. The policy theory assumes three means, ten goals and 24 causal mechanisms. The policy theory is insufficiently empirically substantiated on a number of points and takes limited account of (cognitively) impaired prisoners. This accurate reconstruction offers a unique insight into the assumed functioning of a part of Dutch detention policy and provides starting points for international considerations of behavioral change in detention.

It has been proposed that when people perceive their treatment by criminal justice actors as more procedurally just, they will be more likely to comply with the law. Existing research mainly focused on the police or the judge. This longitudinal study examined how prisoners experienced their treatment by five different criminal justice actors using data from the Prison Project. The prisoners were most positive about the procedurally fair treatment by their lawyer and least positive about the treatment by the police. Additionally, the perceived treatment by the police was associated with the treatment by other actors at subsequent moments.

Prisoners often encounter multiple barriers when returning to society, resulting in higher risks of recidivism. To overcome these barriers, prison-based and community-based professionals assist with preparation for release. Prison-based professionals, such as the case manager and mentor, screen and monitor the problems regarding work and income, housing, healthcare, financial debts and valid identification. Community-based professionals, such as municipal officials, parole officers, healthcare professionals and volunteers, can provide additional and specialized help. First, this research discusses the current policy of the Dutch Custodial Institutions Agency (DJI) and the role of different types of professionals. Second, it presents a nationwide picture of the extent to which prisoners report contact with prison-based and community-based professionals, and to what degree prisoners appreciate this contact. The results are specified for various types of regimes and time served and are based on 4308 prisoner surveys of the Dutch Prison Visitation Study (DPVS), part of the Life in Custody Study (LIC-study). It turns out that most prisoners seem to be in close contact with prison-based professionals and that prisoners positively value this contact. However, contact with community-based professionals is limited and prisoners are somewhat dissatisfied about their contact with parole officers and municipal officials. Furthermore, the amount of contact differs across various types of regimes and time served. In particular, individuals who recently entered prison report less contact. To conclude, policy implications will be discussed.

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.

An exceptionally high prevalence of financial debt problems can be found among prisoners, but criminological knowledge on the link between debts and crime is limited. Previous studies are hindered by a lack of information on types of debts, informal debts and background characteristics. This article provides first and detailed insights in the types and amount of debts during and after prison in the Netherlands. Based on data from the Prison Project we show that the majority of prisoners report having debts during prison, show how different types of debts are related and how these debts change six months after release.

Recently a project was started that aims to systematically describe and explain the developments in the Criminal Code for the period 1886 - 2017. This article presents the first results of this new project, called the Historical Criminal Code (HWvSr). An overview is given of the long-term developments in the structure – the ‘external’ structure – of the Second Book of the Criminal Code since 1886. The analyzes show that its scope has been substantially expanded over the last 130 years, but also that various articles and article parts have been deleted. The article describes the most important changes in terms of both quantity and content.

Little is known about how ex-prisoners’ parole supervision experiences relate to desistance. The aim of this article therefore is to gain insight into the nature of release conditions and parole supervision of ex-prisoners and parolees’ perceptions of their supervision related to the desistance process. A total of 23 Dutch parolees were interviewed in depth at three waves starting in prison up to one year after their release, and the 69 interviews were combined with their parole files containing information about conditions, violations and sanctions. Parole files revealed the practice of highly engaged parole officers, who worked with parolees to strengthen factors known to foster desistance. However, the interviews showed that most parolees found their parole experience predominantly surveillance-oriented and not very helpful for desistance. Parole was experienced as most beneficial when parole officers used their discretionary power to adjust conditions creating ‘space’ for trial-and-error.

This article studies the development in the prison system over the period 1837-2016 in the Netherlands. It describes trends in three characteristics of the Dutch prison system: (a) the number of prisoners, (b) the number of cells, and (c) the inflow of persons from the free society. The findings are twofold. On the one hand – when examining absolute numbers – the article shows that three distinct periods can be distinguished: a period of 140 years with low stable numbers (1837-1975), four decades in which the numbers tripled (1975-2005), and a subsequent decade where the numbers halved (2005-2016). On the other hand – when examining relative numbers, i.e. per 100.000 inhabitants, and thus controlling for the growth in population – the article displays that developments in the prison system in the Netherlands between 1837-2016 can best be characterized by a long-term continuous decrease in detention.

In the current criminological literature surprisingly little is known about the development of partnerships of detainees during and after detention. In particular, it is unknown to what extent existing differences in the relationship quality at the start of the detention period continue. Therefore, this study examined how the partnerships of detainees developed by using data from the Prison Project. This is a longitudinal study in which 747 detainees with a partner were interviewed at various moments during detention and six months after detention. The results show that bad partnerships at the beginning of detention remain in general bad or end during and/or after detention, while the average to good relationships remain the same.

This contribution summarizes findings from the Prison Project on the longitudinal course of mental health problems during imprisonment. The findings illustrate that prisoners experience high levels of mental health problems. Shortly after their arrival in detention, a quarter of them experienced a high level of mental health problems, which is five times as high as men in the general population. Prisoners’ mental health problems decreased during imprisonment. Both characteristics of the correctional environment (e.g. a fair and respectful treatment by prison staff) and pre-existing characteristics of the prisoners (e.g. personality traits) are related to the course of mental health problems in detention.

This study focuses on a sample of 28 male long-term prisoners in the Netherlands who are about to return to society. The aims of the study are to examine their future expectations regarding criminal behavior and to explore how social and individual factors, such as employment, family support and agency, relate to these expectations. This is important because such expectations may affect their actual (criminal) behavior after release. Pre-release semi-structured in-depth interviews included questions about their future expectations, social ties, and sense of agency. Prisoners expecting to quit with criminal activities had both close social ties to society and scored high on individual factors.

This paper examines the relationship between imprisonment length and registered recidivism. The data come from a unique longitudinal and nationwide study of Dutch male prisoners, serving an average of 4.1 months of confinement (N=1,467). Ideally an experimental design would be appropriate to examine the influence of different sentence lengths on recidivism. In order to approximate such a design using observational data, we adopt a propensity score methodology to control for selection bias in the dose-response relationship. Using a six-month follow-up, we do not find significant differences in post-release recidivism between men who spent shorter or longer periods of time in confinement. We discuss the pros and cons of the methodology applied as well as potential implications of the findings.

Studies indicated that detainees are not always allocated to treatment programs based on official guidelines. Street-level bureaucracy theory suggests that this is because government employees do not always perform policies as prescribed. This study aimed to assess whether this also applies to the allocation of offenders to treatment in Dutch penitentiary institutions. This was studied among a group of 541 male prisoners who participated in the Recidivism Reduction program. The results showed that official policy guidelines were, in most cases, not leading when referring detainees to behavioral interventions. Instead, treatment referrals were influenced by a broad range of risk factors, as well as the length of an offender’s sentence.

Although good and stable housing is one of the requirements for successful reintegration, research on the relation between imprisonment and housing is scarce. This study gains insight into the housing situation of Dutch prisoners before and after their incarceration. Data are used from 886 male Prison Project participants, who were interviewed both during and six months after detention. Changes in housing appear to be common; 52 percent of the prisoners has a different housing situation after release (compared to before detention). Changes in housing remain frequent during the six months post-release. The importance of good aftercare in the transition from prison to stable housing is underlined by these results.

The current study examined the extent to which risk factors and treatment readiness were related to prison based treatment engagement (i.e. participation and completion), using a large sample of detainees who were a candidate for the Prevention of Recidivism program. Analyses showed that offenders who were treatment ready were over two times more likely to complete treatment programs, compared to offenders who were not. Risk factors did, for the most part, not correlate with treatment participation and completion. Outcomes underlined the importance of motivational aspects and showed the significance of enhancing treatment readiness amongst correctional resocialisation participants.

Employment is believed to function as a ‘turning point’ for released offenders. Several theories state that employment can diminish recidivism, and offer different mechanisms to connect employment and crime, such as job stability and job quality. This study examines the effect of employment and employment characteristics on recidivism among Dutch ex-prisoners. Although recidivism risks are high among this group, longitudinal research on the effect of employment on recidivism risks is scarce. We based our analyses on longitudinal data of the Prison Project (n=842) and found that job stability reduces the risk of recidivism. The results indicate that not the guidance to a job, or a high-quality job, but the guidance to stable employment could help to reduce crime rates among this high-risk offender group.

Not only detainees, but also their spouses can experience negative consequences of imprisonment. Even though these negative consequences can be far-reaching, research in this area is scarce. This paper researches if detention causes female partners of male detainees in the Netherlands to experience negative reactions from family, friends and neighbours and if this causes changes in their social contacts. This study used longitudinal data from the Prison Project on 119 partners of detainees. Results show that many partners of detainees receive negative reactions from their network members. When partners of detainees experience negative reactions from their family in law, friends or neighbours, their contacts with those groups decrease. When partners of detainees experience negative reactions from their friends, their contact with their family increases.

Both in punishment theory and sentencing practices, the subjective sentence severity is an important yet neglected area of research. This paper aims to explain differences between inmates in their subjective severity of imprisonment and to contemplate these against the background of important sentencing goals and sentencing principles. Two models commonly used to explain adjustment to prison life were applied: the import and deprivation model. Data from the Prison Project, collected among Dutch inmates staying in pretrial detention, reveal that both import and deprivation characteristics are related to the subjective severity of imprisonment. No support is found for a moderation effect of personality.

A survey of the literature suggested that low participation rates in prison-based rehabilitation programs in The Netherlands can be explained by a lack of treatment readiness amongst rehabilitation candidates and participants. The current contribution aims to examine treatment readiness amongst detainees that have been assigned a candidate for a prison-based rehabilitation program in the Netherlands. To address these aims, data were used from the fourth wave of a research project studying the effects of imprisonment on the life of detainees in the Netherlands. Results showed that about eighty percent of treatment candidates were not treatment ready. This lack of treatment readiness amongst potential participants will no doubt influence both treatment engagement numbers, which studies have shown to be low, and quite possible treatment effectiveness. Results imply that practitioners should be aware of the absence of treatment readiness amongst a large part of their clients. Assessment and (if necessary) interventions to increase treatment readiness amongst candidates and participants seems of the utmost importance.

In an attempt to reduce re-offending rates in the Netherlands, the Dutch government has developed the Prevention of Recidivism program, which started in 2002. The current study aims to describe the content of this program, and aims to give an overview of the state of the art concerning the execution and effectiveness of the program. Results show that the number of detainees taking part in the program is fairly limited. Moreover, in many cases, correctional interventions are not part of the imposed rehabilitation program. An extensive literature study shows that the execution of the Prevention of Recidivism program and various correctional intervention show a number of implementation problems, which probably hamper the program’s effectiveness. However, further research is necessary to assess if the Prevention of Recidivism program successfully lowers recidivism rates amongst program participants.
