European probation and prison services are nowadays faced with large numbers of mentally ill people. The reduction of community mental health services all over Europe over the past several decades has led to the criminalisation of the mentally ill. The prevalence of various mental health problems among probationers and prisoners is considerably higher than in the community. In that sense, CEP aims to share experiences and good practices between CEP-members, experts on mental health in probation, in order to improve programes, interventions and ways of working with people under probations suffering mental health problems.
