Objective To determine whether adding web-based support (e-coachER) to an exercise referral scheme (ERS) increases objectively assessed physical activity (PA).
Design Multicentre trial with participants randomised to usual ERS alone (control) or usual ERS plus e-coachER (intervention).
Setting Primary care and ERS in three UK sites from 2015 to 2018.
Participants 450 inactive ERS referees with chronic health conditions.
Interventions Participants received a pedometer, PA recording sheets and a user guide for the web-based support. e-coachER interactively encouraged the use of the ERS and other PA options.
Main outcome measures Primary and key secondary outcomes were: objective moderate-to-vigorous PA (MVPA) minutes (in ≥10 min bouts and without bouts), respectively, after 12 months. Secondary outcomes were: other accelerometer-derived and self-reported PA measures, ERS attendance, EQ-5D-5L, Hospital Anxiety and Depression Scale and beliefs about PA. All outcomes were collected at baseline, 4 and 12 months. Primary analysis was an intention to treat comparison between intervention and control arms at 12-month follow-up.
Results There was no significant effect of the intervention on weekly MVPA at 12 months between the groups recorded in ≥10 min bouts (mean difference 11.8 min of MVPA, 95% CI: −2.1 to 26.0; p=0.10) or without bouts (mean difference 13.7 min of MVPA, 95% CI: −26.8 to 54.2; p=0.51) for 232 participants with usable data. There was no difference in the primary or secondary PA outcomes at 4 or 12 months.
Conclusion Augmenting ERS referrals with web-based behavioural support had only a weak, non-significant effect on MVPA.

Contributors AT conceived the idea for the study with co-applicants: RST, NM, KJ, LY, NKA, JC, CG and SGD. AT, all co-applicants listed above, and WI contributed to the final study design and development of the protocol. AT, JL and LY developed the web support using LifeGuide. SGD led the qualitative work and developed the process evaluation plan with JL, CG, JC and AT. RST provided the statistical analysis plan, and conducted and reported the statistical analysis in accordance with the Plan. AS provided additional support to the statistical analysis. LP was responsible for accelerometer data processing, advising and reporting on accelerometer-derived measures. AT, KJ and NM were principal investigators, assisted by CM at the Glasgow site. WI was the trial manager.All authors critically revised successive drafts of the manuscript and approved the final version. AT is the guarantor.
