Notable studies
S.M.I.L.E. Lightning Process trial

SMILE was a pilot trial on children with ME/CFS and involved comparing the effects of standard medical treatment (SMC) against that of the Lightning Process & SMC. The initial budget was £164,000 funded by the Linbury Trust and the Ashden Trust.

Children aged 12 to 18 were drawn from the Bristol & Bath areas, with those too unwell to attend hospital appointments excluded. The charity Association of Young People with ME (AYME) was a participant in the trial and gave evidence in support during the trial ethics procedure.

A Freedom of Information request asking for the cost of the trial and payments to Phil Parker were turned down as they university states the "information is held by the University but is exempt from disclosure under section 22(1) of the Freedom of Information Act as it is information intended for future publication."

MAGENTA trial

Prof Crawley is studying CBT and GET in children. . The protocol and peer review history have been published.

The trial started in September 2015 and studies 100 paediatric patients aged 8-17 in centres in Bath, Newcastle and Cambridge who randomly receive graded exercise therapy or activity management. It aimed to be completed in August 2016.

FITNET online CBT study

This is a major study led by Dr Crawley funded by the NIHR which began in May 2016 and is due to be completed by May 2022. The projected cost is £994,430 and participants include UMC Utrecht and Radboud University Medical Centre in the Netherlands. The charity AYME and the Science Media Centre are also involved to "help us inform patients".

The study aim is to test FITNET-NHS (specialist CBT for paediatric CFS/ME delivered on-line) compared with Activity Management in terms of cost-effectiveness and clinical success.

Controversies and Criticism
SMILE Trial

In a joint statement in August 2010, the ME Association and the Young ME Sufferers Trust called the SMILE study "unethical". They quoted the Medical Research Council guidelines on research in children - "Research involving children should only be carried out if it cannot feasibly be carried out on adults. The ME Association and The Young ME Sufferers Trust do not believe that it is ethically right to use children in trialling an unproven and controversial process such as the Lightning Process." Invest in ME in a letter to the National Research Ethics Committee (NRES) described the process as "rather like CBT but with bullying and risks of harm".

James Coyne has criticised Crawley's work with regard to public availability of data & the involvement of Phil Parker in the SMILE study.

Daniel Clark has noted that the primary outcome measure was changed from school attendance to scores on a self-report questionnaire. He stated, "Given that LP involves making claims to patients about their own ability to control symptoms in exactly the sort of way likely to lead to response bias, it seems very likely that this trial will now find LP to be 'effective'."

The study only received final ethical approval after prolonged protests from patient groups in January 2011.

MAGENTA Trial

James Coyne has urged patents not to enrol their children in the trial. He has highlighted the lack of information given to patients about potential harm, the consent procedure and the lack of published data on previous studies.

Complaints and Death Threats

Dr Crawley has been the subject of complaints to the General Medical Council (GMC) and claimed to have received death threats

Canadian Consensus Criteria

In an reply to an Editorial in the British Medical Journal by Fiona Goodle, Crawley (with Peter White and Alastair Miller) rejected using the Canadian Consensus Criteria to diagnose patients, labelling it as "not practical", although conceding post-exertional malaise (which is part of the criteria) "may need incorporating in future definitions to help differentiate CFS from more general fatigue."

Prevalence at Age 16

In a study published in 2016 using data from almost 6000 children in the Children of the 90s Project, Crawley and her team concluded that the prevalence of CFS at age 16 was 1.8%. However, the children were included as having CFS on the basis of questionnaires, no doctors were involved in the diagnosis, and there was no attempt to exclude other fatigue-related conditions except depression. If children reporting depressive thoughts were excluded, the prevalence was reduced to 0.6%, but the 1.8% figure was highlighted in the media. BBC Radio 4 coverage described the condition studied as ‘ME also known as chronic fatigue syndrome’. Dr Charles Shepherd of the ME Association wrote to express concerns about the methodology used but the journal did not publish his letter

Freedom of information requests
A number of Freedom of Information requests have been made to Dr Crawley about her work. One request revealed records were not kept of patients subsequently re-diagnosed with another illness at Dr Crawley's paediatric clinic.
