This study aims to determine whether augmenting usual ERS with web-based behavioural support, based on the LifeGuide platform, will increase long-term physical activity for patients with chronic physical and mental health conditions, and is cost-effective.
Methods and analysis: A multicentre parallel two group randomised controlled trial with 1:1 individual allocation to usual ERS alone (control) or usual ERS plus web-based behavioural support (intervention) with parallel economic and mixed methods process evaluations. Participants are low active adults with obesity, diabetes, hypertension, osteoarthritis or a history of depression, referred to an ERS from primary care in the UK.
The primary outcome measure is the number of minutes of moderate to vigorous physical activity (MVPA) in ≥10 minute bouts measured by accelerometer over one week at 12 months.
We plan to recruit 413 participants, with 88% power at a 2-sided alpha of 5%, assuming 20% attrition, to demonstrate a between group difference of 36 to 39 minutes of MVPA per week at 12 months. An improvement of this magnitude represents an important change in physical activity, particularly for inactive participants with chronic conditions.
Ethics and dissemination: Approved by North West Preston NHS Research Ethics Committee (15/NW/0347). Dissemination will include publication of findings for the stated outcomes, parallel process evaluation and economic evaluation in peer-reviewed journals.
Results will be disseminated to ERS services, primary healthcare providers and trial participants.
