This study uses qualitative research consisting of six semi-structural interviews of treatment workers who, in various capacities, have worked with men who use violence against their female partners. The purpose has been to show what the treatment counselor understand to be the reasons behind the men’s violence, what kind of backgrounds and problems they believe these abusers have and, lastly, how they view the male abusers as clients. The empirical data was analyzed through four perspectives and explanatory models derived from the past thirty years of Scandinavian research on the reasons behind men’s violence against women. Connell’s theory of masculinity was used as a filter along with the four theoretical perspectives when interpreting the data. The study revealed that the respondents found no consistent group of men who abuse. The respondents brought up reasons such as possible earlier exposure to violence, fear of abandonment, jealousy, feelings of powerlessness, and failed expectations of gender roles to be some consistent causes behind the violence. In general, according to the treatment workers, the male abusers they encounter tend to struggle with their self-image and how they fulfill perceived male ideals.
