What’s Ken thinking?

Last post: 16 July 2024

Ken McMaster blogs about the many issues faced by the human services sector in our modern age.

Listen to our podcast!

Talking with Ken features conversations with industry professionals about the past, present and future practices of the domestic violence intervention field.


How do we increase the dosage in our men’s behaviour change programmes?

How do we ensure the learning transfer of our work in programmes continues after the session?


These questions have been central to our thinking over the past forty years. We know that engagement is central to programme outcomes. We know that ideas we share in programme sessions lose their currency quickly after sessions, and many men do ‘time’ with us rather than ‘change work’.

Therefore, we are excited to announce our new programme support app Ake soon to be available to your Service Users on iOS and Android devices tackling these issues by bridging the gap between the group sessions and home.

Find out more about Ake and how it works below.
