The problem is not CBT per se, but the absence of a biomarker.
To bring this discussion back to MEGA/OMEGA, I’m not sure that EC is at all interested in finding biomarkers from the MEGA project. If we look at what she apparently said in 2010 - From
https://meagenda.wordpress.com/2010...presentation-the-future-of-research-in-cfsme/ - we get a better understanding of what she wants to use the genomic data for.
“What we’re interested in doing is finding risk factors that we can change. So that’s either going to be drug treatments or other risk factors that we can change.” She later lists the risk factors –
“Slide 32: Risk Factors
• Known: Older age; female; lower SE class; heritable component; infection
• Trauma: Heim ’09 Retrospective case – control [*1 see below]
• Ethnicity: Dinos ’09: meta analysis – ↑Native Americans OR 1.5 (CI1.08 – 56.4)
• Mood: Harvey ’08 “Psychiatric illness” in adults [*2 see below]
• Systematic review: Hempel 2007: none replicated [*3 see below]
Hempel 07; Katz 09; Heim 06 & 09; Kerr 08
[she continues -] These are the known risk factors for chronic fatigue syndrome. We’ve already talked about heritability, lower socio-economic class, older age, female and infection. For a long time, we’ve known that infection was a trigger for chronic fatigue syndrome. All these other ones have not been reproduced.
OK, so people talk about it, not been reproduced, don’t know if they’re true or not.”

It seems that these other ‘risk factors’ are actually what she is interested in researching, not biomarkers. How many of them are biomedical and how many psychosocial? You decide. To help here are the references –

Childhood trauma and risk for chronic fatigue syndrome: association with neuroendocrine dysfunction
RESULTS - Individuals with CFS reported significantly higher levels of childhood trauma and psychopathological symptoms than control subjects. Exposure to childhood trauma was associated with a 6-fold increased risk of CFS. Sexual abuse, emotional abuse, and emotional neglect were most effective in discriminating CFS cases from controls. There was a graded relationship between exposure level and CFS risk. The risk of CFS conveyed by childhood trauma further increased with the presence of posttraumatic stress disorder symptoms. Only individuals with CFS and with childhood trauma exposure, but not individuals with CFS without exposure, exhibited decreased salivary cortisol concentrations after awakening compared with control subjects.
CONCLUSIONS:
Our results confirm childhood trauma as an important risk factor of CFS. In addition, neuroendocrine dysfunction, a hallmark feature of CFS, appears to be associated with childhood trauma.

The relationship between prior psychiatric disorder and chronic fatigue: evidence from a national birth cohort study. Harvey SB1, Wadsworth M, Wessely S, Hotopf M.
CONCLUSIONS:
This temporal, dose-response relationship suggests that psychiatric disorders, or shared risk factors for psychiatric disorders, are likely to have an aetiological role in some cases of CFS/ME.

Risk factors for chronic fatigue syndrome/myalgic encephalomyelitis: a systematic scoping review of multiple predictor studies.
CONCLUSIONS:
Various potential risk factors for the development of CFS/ME have been assessed but definitive evidence that appears meaningful for clinicians is lacking.
Incidentally she also remarked in this talk that “we must include the severely affected and children.”
