Almost half of all people with schizophrenia will relapse within five years post-diagnosis [Within clinical services, EWS-based relapse prevention relies on patients, mental health staff and carers monitoring for EWS and reacting promptly to prevent a relapse event which appears to reduce relapse rates [The Early Signs Monitoring to Prevent Relapse in Psychosis and Promote Well-Being, Engagement, and Recovery (EMPOWER) intervention [Human contact is important for active engagement in digital interventions for psychosis [The primary trial outcomes indicated that overall EMPOWER was feasible, acceptable and safe. This was indicated by high levels of recruitment and retention, the intervention meeting its a-priori feasibility criteria for intervention adherence and low levels of adverse events. Due to this result, there is need to understand how and why the intervention was implemented in the context of this trial. Implementation behaviours describe what people do when exposed to a new intervention, and understanding implementation behaviours require consideration of context and influences on behaviour (including subjective experiences) [Implementation research has historically focused on the experiences of healthcare staff [Process evaluations are useful for understanding implementation behaviours and what underpins them because these studies investigate the different components of a complex intervention, how it is delivered, and what happens when people interact with an intervention. Process evaluations conducted in feasibility trials can improve the validity and interpretation of outcomes, help refine the intervention, and provide necessary information to help inform upscaling decisions or outline the need for intervention refinement [
