The effectiveness of digital tools in physical activity interventions for individuals with severe mental illness: a scoping review

14 studies found an increase in PA. Walking was the most common form of PA. The most frequently utilised digital tool was an accelerometer. Group PA was more frequent than individual PA. Many studies used supervision within the intervention. Outcomes varied across studies.<b>Conclusion:</b> Digital PA interventions vary in design and show promise in increasing PA amongst the cohort. However, further research is needed to determine the feasibility and acceptability of digital tools and to incorporate different elements into the design of digital PA interventions, particularly for a long-term solution.
