The Prison Project is a large-scale longitudinal research project examining the effects of imprisonment on the further life course of offenders and their families. Males who were put in pre-trial detention in all remand centers in the Netherlands between October 2010 and April 2011 were asked to participate in the study. Respondents who participated in our study were followed for four years, and questioned repeatedly regarding their lives before, during and after imprisonment. In this way, elaborate information was gathered on multiple life domains (e.g. criminal behavior, employment, housing situation, social networks, health, wellbeing of family members). In addition, officially registered data - e.g. on their criminal behavior, participation in behavioral interventions, and disciplinary infractions during their time in prison - were collected.

In 2017 The Prison Project received the Correctional Research Award 2017 of the 'International Correctional and Probation Association' (ICPA).
