As originally designed Cognitive Behavioural Therapy is not very child friendly. In Pesky gNATs we have used our understanding of developmental psychology, clinical psychology and computer science to tackle the problem of translating the adult oriented ideas of CBT into something that is accessible to younger children. This video introduces the key elements of Pesky gNATs.

Pesky gNATs was orginally developed by Handaxe CIC, a not-for-profit community interest company founded by David Coyle and Gary O’Reilly. As of April 2025, the software and website will be hosted by Opposable Games Limited, the development partners of Handaxe CIC.
