Funding
The development of Prevail, its implementation to the DVLA, and the costs of the RCT were funded by the DVLA via a research grant to Swansea University (Ref number: PSC1046). The funders helped in the implementation of the RCT via selecting appropriate managers and their teams, randomising these managers/teams to the active and control arms of the study, delivering the Prevail intervention via a train-the-trainer programme, and tabulating data on sickness absence from their official records. All data entry, statistical analysis, and writing of the manuscript was done independently of the funders, although the funders had sight of the report and were invited to give comments and suggestions.
