The traumatic pasts of criminalised women affect their present.

One Small Thing works with staff in women’s prisons and in the community, developing approaches grounded in understanding, fostering positive outcomes for all. We call this trauma-informed practice.

Lady Edwina Grosvenor established One Small Thing to champion trauma-informed practice with criminalised women. It is run by the Centre for Crime and Justice Studies.

Why One Small Thing?

Our name reflects the value of those small things – like compassion, understanding, respect – and their power to make a big difference.
