Generative AI-Enabled Therapy Support Tool Improves Clinical Outcomes and Patient Engagement in NHS Talking Therapies

Cognitive behavioural therapy (CBT) is a highly effective treatment for depression and anxiety disorders. Nonetheless, a substantial proportion of patients do not respond to treatment. The lack of engagement with therapeutic materials and exercises between sessions - a necessary component of CBT - is a key determinant of unsuccessful treatment. Here we tested whether the deployment of a generative artificial intelligence (AI) powered personalised therapy support tool supporting patients in between sessions leads to improved treatment success and patient engagement with treatment. We conducted a real-world observational study of 137 patients receiving CBT in five of the UK’s National Health Service (NHS) Talking Therapies services. Ninety-three patients (68%) used the AI-enabled therapy support tool whilst forty-four patients were provided with the standard CBT worksheets. Patients using the AI-enabled therapy support tool exhibited greater attendance at therapy sessions and fewer dropouts from treatment. Furthermore, these patients demonstrated higher reliable improvement, recovery and reliable recovery rates when compared to the control group. Within the intervention group, the degree of usage of the AI-enabled tool was directly related to the number of attended therapy sessions and reduced dropouts. Our results thus show that an AI-enabled, personalised support tool is a promising avenue to improve treatment outcomes and patient adherence.
