**Phase 10 was a pilot carried out in February and March 2011. A small group of Stress and Health participants were selected randomly and invited to attend our Phase 10 clinic. This enabled us to successfully pilot new measures for mental well-being introduced at Phase 11.

 

The study is approved by the London-Harrow Research Ethics Committee and the Scotland Research Ethics Committee. All participants who had clinical examination were asked to give written informed consent.
