Since Sweden has a reputation for having a pragmatic, technocratic approach to solving social problems, the question arises as to why the country uses different methods at the national and the local level for treating violent men. If studies show that one method is superior to others, we would expect both levels of government to use similar treatment methods. Despite the emphasis on pragmatic solutions, ideology plays an important role, as the Swedish government in recent decades has largely accepted the New Public Management approach to governance. However, because of differences in institutional arrangements, it becomes logically appropriate for the national level to utilize a different type of therapy (Cognitive Behavioral Therapy) than the local level (Psycho Dynamic Therapy among others). Thus, a combination of an ideological shift to New Public Management and institutional differences can explain the differences in therapeutic approaches, rather than reliance on scientific studies.
