The empirical part focusses the Forensic Center in Asten, where the data was collected. Forensic treatments are analysed with quantitative methods to find out which factors influence the allocation of the treatments and if the classification is done in a client-centered way. The accumulating sample (qualifying date: 18.9.2017) includes 132 mentally abnormal sane incapable men. The descriptive analysis is used to describe the collected variables (age, diagnosis, crimes, risk evaluation and so on). Bivariate and multivariate correlation-analysis are applied to get information about the connection between treatments and collected items and to find out if and how they influence the assignment of treatments. The empirical results represent the client-centered orientation of the allocation of treatments in the Forensic Center in Asten. The logistic stepwise regression can explain the assignment of the treatments quite well, the most influencing items are the risk evaluation and the weakening step.
