In the Deary et al. [
13] model of MUS, the patient is to be challenged on the origins of symptoms such as pain or fatigue - the patient is said to perpetuate their own illness by holding on to beliefs in an ‘organic’ illness (ME/CFS caused by infection for example). The notion patients’ beliefs perpetuate illnesses such as ME/CFS, IBS or Fibromyalgia, is based more on speculation than evidence. In contrast, there is considerable growing evidence showing ME/CFS is indeed linked to biological dysfunction following infection [

35]. The IAPT model of MUS may put CBT therapist and patient on a collision course – far from Beck’s collaborative journey. To what extent will the CB Model of MUS be disclosed to patients remains to be seen [
41]. We speculate many MUS patients will be told very little about the therapies they will receive in IAPT, before agreeing to participate. We further speculate that if the rationale behind CBT is disclosed to MUS patients, many will reject treatment or withdraw from treatment – we see high dropout rates in early IAPT provider data [
