"We encourage men to talk about the relationship between their beliefs, thoughts, feelings and violence. Most men have managed to convince themselves that their violence is about losing control. The programme helps these men understand that their violence is actually about gaining control over others," Mr Steedman said.
"Once they understand that they are in control, it can free them to consciously decide that they no longer want to continue using violent behaviour."
Research showed that group programmes were more effective than individual counselling at developing ideas, attitudes and behaviours which support respectful, safe and caring relationships with partners, children and family members.
Mr Steedman said if people were worried about their behaviour with a partner or family member and wanted to make positives changes, they could call the Shine Helpline 0508-744-633 (7 days/week, 9am 11pm).
