I wrote the following when the thread was in an earlier stage but will share anyway, though it's a bit long...
Several things come to mind (though I haven't read the paper either):
(1) Blame the victim
(2) Arrogance; (Are such psych theories more common in cultures (and/or cultural circles) where arrogance is a more accepted trait?)
(3) CDC (to some degree at least) has stated that the severity of the initial infection predicts the development of ME/CFS. CDC has also said (to my understanding) that racial/ethnic minorities and low-income individuals are disproportionately affected by ME/CFS (within a US context at least, I assume).
Additionally, and though ME/CFS was not particularly named, I know that a Swedish report on discrimination within healthcare stated that immigrants were less likely to be treated in a timely manner and that this delay in services contributed to worsened health outcomes.
In a US context, I'm assuming that racial/ethnic minorities and low-income individuals are those who might generally have the least access to healthcare and/or quality healthcare. Within European healthcare systems, I'm assuming that healthcare resources/rationing affect timely treatment (for everyone) but immigrant status (or any "negative" status marker, so to speak) can further negatively affect the quality of care received - and thus outcome.
I know also that at least one retired Swedish lawyer was working to help ME/CFS patients and that he said many-to-most of his clients were immigrant women with low Swedish-language skills. I believe as well that in at least one (UK I believe) ME/CFS literature review, one research gap was that studies excluded individuals with little-to-no English language skills.
I don't know the background of the researchers in question, and perhaps they came from very humble beginnings. But no matter where they came from, they are in a to-some-degree privileged position now. If nothing else, they (most likely at least) have the privilege of not having ME/CFS.
Long story short: It should be questioned as to what degree researchers who are most often privileged by social status, income, neighborhood, health, language ability, whatever - it should be questioned as to what degree such individuals can ethically/accurately define/identify/rate various forms of catastrophizing.
Maybe their research should be presented like this: Predominately middle upper-class and/or white male researchers assert that individuals (especially women, poor women, racial/ethnic women, immigrant (refugee?) women, and women with limited second-language ability) frequently exaggerate the pain they experience from untreated chronic disease. :/

Use your power for good??)

EDIT: Also to consider in regard to social inclusion/exclusion: I believe a well-recognized research gap has been that those too ill to travel or participate in clinic therapy sessions have been excluded from research. I would like to propose that those with low incomes - who may have financial difficulty in accessing appropriate transportation or who may not be able to afford a sitter (for children), for example - that these individuals may have also been excluded from studies. (Maybe study participants receive some kind of financial assistance??)
I recently also asked what rights persons with ME/CFS (should) have in accessing public meetings through audio/audio-visual archival*. This of course also affects those too ill to participate in person and/or those who can't afford to participate in person.

Consider also, please: UN Convention on the Rights of Persons with Disabilities
Recognizing that disability is an evolving concept and that disability results from the interaction between persons with impairments and attitudinal and environmental barriers that hinders their full and effective participation in society on an equal basis with others
