Drug policies may have less impact on cannabis use than is currently thought.

The SCIL appears to be a time-efficient tool for screening for MBID in adults (18+) and juveniles of 14 years or older.

Purpose – The Dutch Custodial Institutions Agency has commissioned a number of research projects on offenders with intellectual disabilities (ID) in prison. A continuing problem has been that it is not known what the prevalence of ID in Dutch prisons is, and how to identify ID in individual detainees. The paper aims to discuss these issues. Design/methodology/approach – With this in mind a screening instrument (screener for learning disabilities and intelligence (SCIL)) has been developed that screens for IQ < 85. This instrument has been piloted in four different penitentiary institutes. Findings – The papers briefly describes the results of the studies preceding the pilot before turning to the pilot itself. The pilot shed light on what considerations need to be taken into account when implement screening for ID in the current prison system, and on the potential added value for prison staff of knowing whether a detainee possibly has an ID. In addition, the pilot gave some insight into the characteristics of Dutch prisoners. Originality/value – The main conclusion is that the SCIL can be successfully implemented within these settings, provided that sufficient attention is being paid to the advance instructions to staff and to the introduction of the screening to the detainees.
