I am only several minutes in, and so far, either directly or by implication, there are very many provably false things, and either direct or implied fallacies. Its not worth watching unless you are interested in this kind of psychological material.
There is a nice slide from some old Komaroff research showing that using SF-36 people with CFS are typically (and not for all roles) worse than diabetics or those with MS.
At about 11 minutes the model is revealed. Its a deconditioning avoidance model, typical psychogenic nonsense.
There are lots of analogous inferences. We think something is happening in some other condition, so we think this applies to CFS.
A lot of this is based on the Expressed Emotional methodology, from the 60s, but the explanation is unclear as it switches from empirical to theoretical comments. I do not know enough about this to comment specifically, but many such techniques fall into the psychobabble category.
There is repeated failure of disambiguation between association and causation. This mostly by implication, not actual statement. What is surprising is that some of these claims may be somewhat testable, that is a predicted causative effect might, in a well designed study, be capable of refutation, and failure to refute may uphold it. I wonder why they don't do so?
They are looking at creating interventions for careers and significant others. In other words, CBT on people supporting CFS patients.
One interesting comment at the end is that they produced educational packs, sent them to GPs, and nearly all were lost. Educating GPs and patients is likely to be problematic.
There is almost nothing of much use in this video except a few snippets. For anyone wanting to see how psych goes off the rails then this might be of limited use.
PS Lots of mention of the FINE trial, but no mention of its failure to help.
