Methodology
The outcome was initially to be based on school attendance. This was changed to assessment based on the following scales: the Chalder fatigue scale, pain visual analogue scale, physical function short form (SF-36), the Spence Children’s Anxiety Scale (SCAS), the Hospital Anxiety and Depression Scale (HADS) for children aged 14 and over,  and the Euroqol (EQ-5D), a five-item quality of life inventory.

Out of 156 children considered eligible, 56 participated, with the study beginning in September 2012.

Funding
The initial budget was £164 000 funded by the Linbury Trust and the Ashden Trust.

Results
The results have been not published in paper despite the trial being completed in 2013. There has been no further study following on from this feasibility one.

There are some selective quotes in a 2015 paper as well the final study protocol, which was pulished after the trial ended. James Coyne said of the quotes "(they) cannot be independently evaluated. Readers are not told how representative these quotes, the outcomes for the children being quoted or the overall outcomes of the trial."
