Consort diagram: participant flow into randomised controlled trial. *There was one randomization protocol violation. One participant who was allocated into TAU by the randomisation system was accidentally sent the incorrect treatment allocation letter, resulting in them receiving the RCBT therapy. This error was identified following the completion of treatment. The participant completed outcome data only at three months. **There was an enrolment protocol violation. Two participants in the RCBT group did not meet the criteria of ≥18 on the SHAI. This error was not identified until final analysis and as such both participants were included in the analysis
