AbstractThis investigation studied the interaction between seven risk factors included in the police risk assessment of the VioGén System and found that these factors formed groups based on the dimensions of violence and psychopathology. The 171 femicides analysed were categorised into four groups: normalised (23.4%), violent (25.7%), pathological (18.7%), and pathological/violent (32.2%). These groups exhibited significant differences concerning their psychosocial profile and relationship dynamics. One of the main findings is the identification of the pathological type that had not been detected in previous typologies, thus highlighting the importance of the psychological factor when classifying the perpetrators of femicide. These results have important practical implications, as the classification of the aggressor could be a preliminary step taken before the risk assessment, which would make it possible to individualise predictions and improve the protection of the victims as well as the therapies and intervention programmes.
