There is an important gap in scaling up psychosocial interventions for people with severe mental health problems so that these interventions are not only widely available but also delivered in a timely manner. We examined the feasability of adapting a psychological intervention traditionally delivered face-to-face onto a digital platform. We report both the clinical and technical processes used to adapt and develop the digital platform in a group of people in the early phase of psychosis. The digital platform prompts people to engage with the intervention multiple times a day over a 12-week period. Participants are also able to access a repository of multi-media content to support their mental health. The digital platform has been successfully validated by participants registered with early intervention for psychosis services in the Northwest of England, UK and is currently being tested in a powered efficacy trial.
