Samenvatting

Recent studies show that neurocognitive functioning of people within the criminal justice system might be relevant for judicial intervention and reintegration programs, but the use of this information is hindered by – among other things – a lack of appropriate norm scores for neuropsychological tests. A total of 272 detainees completed the d2 attention and concentration test. This article shows that for the d2 attention and concentration test, the already available norm scores are not appropriate for the use within the criminal justice system. New norm scores for Dutch detainees are provided, based on outcomes of a regression based norm procedure. These norm scores are made freely available.
