Discussion
In order to evaluate the Prevail intervention we assessed, (1) whether the people who underwent Prevail thought that the intervention achieved its aims, (2) whether Prevail produced changes in people’s mental health literacy (including stigma reduction), and (3) whether Prevail changed their ability to work (reduced absenteeism) as indicated by the number of days taken as sickness absence. We found strong evidence that Prevail achieved all three aims.
