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

Severe mental illness (SMI) encompasses a mental, behavioural, or emotional disorder resulting in serious functional impairment, which substantially interferes with or limits an individual's life activities. SMI can include disorders such as personality, psychotic, bipolar and major depression. Incorporating physical activity (PA) into the daily lives of individuals with SMI offers increasing health benefits. Despite the acknowledged benefits of PA, there are barriers to engagement and participation rates remain low. Digital tools in PA interventions are rapidly increasing amongst this cohort and can mitigate these barriers. However, the broader implications of how a digital PA intervention can impact this cohort and act as a long-term solution are often overlooked.Materials and Methods: Seven databases were searched. A search string was developed around three categories: Enduring Mental Illness, Digital Tools, and Physical Activity. Full-text screening was performed, and quality checks were completed. Articles selected for review were exported as a list into Microsoft Excel. 24 articles were deemed eligible for inclusion.

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.Conclusion: 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.
