Brief summary

People with severe mental illness are much more sedentary than the general population, and therefore more susceptible to life limiting diseases such as cardiovascular disease and clinical obesity. This study aims to assess the feasibility and usability of an app and wrist wearable to promote physical activity snacks (<10min in duration) in people with severe mental illness. We hypothesis that the app will be feasible and acceptable for people with severe mental illness. We also hypothesise that prompting people with severe mental illness to do activity 'snacks' will increase their physical activity levels, decrease sedentary behaviour, and improve quality of life.

Interventions

Participants will use an app and wear a wrist-worn Garmin activity tracker for six weeks. The app is designed to prompt users via the Garmin to partake in at least three physical activity “snacks” per day (defined as physical activity bouts of less than 10 minutes in duration). The timing of these prompts will be customisable to the individual, and setup will be supported by a member of the research team during the initial onboarding session. Further support will be provided during weekly follow

Participants will use an app and wear a wrist-worn Garmin activity tracker for six weeks. The app is designed to prompt users via the Garmin to partake in at least three physical activity “snacks” per day (defined as physical activity bouts of less than 10 minutes in duration). The timing of these prompts will be customisable to the individual, and setup will be supported by a member of the research team during the initial onboarding session. Further support will be provided during weekly follow-up phone calls, during which the research team will assist participants in adjusting preferences, addressing technical issues, and gathering information on ongoing capacity to consent and adverse events. The mode of each physical activity snack will be personalised according to participants’ physical activity preferences and capabilities. Participants will select their preferred types of activities from either a pre-determined list or may nominate other activities that suit their needs and abilities. This approach ensures that the intervention is accessible and adaptable to a range of physical abilities and lifestyles. We anticipate the pre-determined list to include the following options: • Walking up and down stairs • Walking outside • Housework/household chores • Other (users will be asked to specify) Adherence to the intervention will be assessed using data retrieved from the Garmin activity tracker, including timestamps and activity intensity, which will be used to determine whether participants completed at least three short bouts of activity per day. These data will be supplemented by weekly self-reports collected during follow-up phone calls to provide additional context where needed.
