Over a period of four years, 269 men completed the Cognitive behavioral group-treatment “Brøsetmodellen”(see below). A randomized sample of 85 men were selected and asked by mail to respond to a questionnaire aspart of a follow-up study, concerning their current use of violence and use of the techniques from their treatment sessions. Ten of the eighty-five men were not traceable. Of the remaining seventy-five, four were unwilling to participate. From this sample (n = 71) 37 (52.1%) participated and 34 (47.9%) did not. A demographic comparison between the responders and the non-responders did not confirm any differences in age, education, income or violence before treatment. The mean age of the responders was 41.8 (27 to 63). Most of them (67.6%) had the equivalent of a college education of 12 to 13 years , 27% had an academic education, 5.4% had no education after primary school (10years), 91.9% lived in a spousal partnership, and 78.3% were fathers with one to three children (Mean = 1.9). At the follow-up, 62.9% lived in the same relationship as before treatment.
