Pesky gNATs


In February 2014, together with Gary O’Reilly, I co-founded Handaxe CIC, a not-for-profit, community interest company dedicated to research and development of technology to support mental health interventions. This company is built on a spirit of generosity. We believe technologies that support mental health services can make an important contribution to society. But only if they are widely available. We aim to make our technologies available free of charge, or at the lowest possible cost to adolescent mental health services. Pesky gNATs was the first product developed by Handaxe Limited. It is a computer game and mobile app that implements core elements of Cognitive Behavioural Therapy and supports clinical interventions for young adolescents experiencing depression and anxiety. We also provide online training for mental health professionals who wish to use our software.

Impact: the Pesky gNATs software is now in widespread use in youth mental health services in Ireland and the UK. This is largely due to the commitment of Gary O’Reilly in supporting training for therapists and helping to ensure the our research has an impact beyond academia. I am very grateful to Gary for his deep dedication.

The initial development of Pesky gNats was supported by the NHS Enterprise East through the SBRI Healthcare. It is also generously supported by University College Dublin and the University of Bristol. Development of the game would not have been possible without our long-term collaboration with the Ben Trewhella and Opposable Games.
