NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
A Mobile Health App to Reduce Sedentary Time in Inactive Employees: Study Protocol for a Single-Group, Time Series Feasibility Trial
Extended bouts of sedentary time are common in the modern working environment. As such, effective interventions are needed to counter the adverse health effects of sitting. We developed a theory-informed, mobile health app (i.e. the ENCOURAGE App) designed to interrupt occupational sitting time. The objective of our study is to investigate the effect of the ENCOURAGE App on the number of breaks in sedentary time taken throughout the day. This is a single-group, time series quasi-experiment evaluating the effect of the ENCOURAGE App on breaks in sedentary time. Data will be collected at baseline pre-intervention, 1-week, 1-month and repeated monthly for 6-months thereafter. We will recruit up to 300 individuals that have downloaded the app using an electronic, mobile consent form. The primary outcome of the study will examine a change in the number of breaks in sedentary time from baseline to one-month. We will also recruit a sub-sample of 60 individuals to collect objective data on physical activity and sedentary behaviour. As the modern working environment continues to promote a sedentary lifestyle, there is an urgent need to identify cost-effective solutions that can be scaled for both small and large organizations. This study aims to develop a novel mobile health app to support employees to reduce their sedentary time and become more physically active. The trial has been registered on ClinicalTrials.gov, a registry database of privately and publicly funded clinical research studies (NCT03403270).
