Comparison of risk of recidivism among sexual offenders with and without sexual preference disorders using the STATIC-99R instrument

Purpose
The STATIC-99 instrument is one of the tools used for the assessment of the risk of recidivism, in line with the actuarial approach. One of the risk factors indicated by the scientific literature as having the greatest significance is sexual preference disorder. The aim of the study was to verify whether sexual offenders diagnosed with sexual preference disorders have a higher risk of recidivism. The study also aimed to present, for the first time in Poland, a quantitative scoring of individual risk factors in STATIC-99R and their prevalence, allowing for the verification of the theoretical validity of the STATIC-99R instrument in the analysis of the population of sexual offenders in Poland.

Methods
The study material consisted of 100 court and penitentiary files of perpetrators of crimes against sexual freedom from 11 Polish penal institutions and remand centers. We used the STATIC-99R to evaluate each case.

Results
The distribution of the individual STATIC-99R risk factors in the population of the Polish sexual offenders is presented. The diagnosis of sexual preference disorders had no influence on the total STATIC-99R score but was associated with its individual factors.

Conclusions
It can be concluded that the theoretical validity of the STATIC-99R tool is also relevant to the Polish study population and may be used in clinical practice.
