Literature widely reports the negative impacts of domestic violence at individual, family, and societal levels. Intervention programs that effectively assist violent men to develop alternate ways of relating, and thus enhance the safety of women and children, are of significant value to governments and the community. This study evaluates the effectiveness of one such program in promoting change in relevant attitudes and psychological constructs. Program participants completed pre-and post-group surveys containing validated scales that measured their gender equity beliefs, self-esteem, mastery, and psychological distress. Over the duration of program attendance, positive changes were evident regarding men's self-esteem, mastery, and psychological distress, however, no significant change in gender equity beliefs was apparent. The positive changes evident amongst participants indicate beneficial outcomes from group work participati on in areas that have been identified as risk factors for violent behaviour. The results also suggest that intervention programs would benefit from an increased focus on gender equity beliefs, and that further research is necessary on the extent to which this focus could improve attitudes, and consequently promote safety for women and children.
