Intimate partner violence (IPV) is an extensive issue in every society. It does not matter what kind of socioeconomic, religious or cultural group an individual belong to since this type of violence is widely-spread across the globe. Studies have shown that IPV perpetrators are not a heterogene-ous group and that risk factors differ between different groups of individ-uals. Therefore, it is essential that the subsequent risk management take this heterogeneity into consideration. The aim of this study was to identify which risk factors can be seen as the most contributory when it comes to assessing the summary risk ratings in a sample of alleged IPV cases where both the perpetrator and the victim shares the same background. The data consisted of 926 B-SAFER risk assessments done by the Swedish Police for IPV cases divided into seven different groups: Sweden, Northern Europe, Europe, Eastern Europe and Russia, Middle East, Africa, and Asia. The results show that risk factors have different impact on the summary risk ratings across groups, where risk factors related to the nature of the IPV and victim vulnerability factors are more common in groups with immi-grant background, while risk factors related to psycho-social adjustment were overall more common in the group of IPV perpetrators with Swedish background. The results are discussed in terms of the integrated ecological framework and from an IPV risk management perspective, as well as in relation to the RISKSAM model.
