- Men's Safety Project site
A site for men (and their partners) wanting to be safe within their relationships. This site is also a great resource for practitioners who work with abusive men. - Motivational interviewing resources
Our favourite tools to support you in your work of building partnership, understanding the importance of empathy, and evoking as much change talk as possible... All while minimising sustain talk of course. - Family violence resources
Family violence is a complex and challenging area for us as practitioners. Having proven resources when working with those who have been abusive can dramatically enhance the safety of those victimised, particularly women and children.
