Did you even read the article? CBT and the cognitive model are not the same thing. CBT (the therapy) works, but that doesn't mean the underlying theory is correct.

"Not only is there contrary evidence showing problems with reasoning are widespread as well as potentially associated with mental health rather than mental disorder. But the evidence in favour of CBT’s take on mental illness is tainted because the tests used in these studies do not even track problems with reasoning. CBT provides a compelling story about mental illness – mental illness is associated with “faulty” reasoning, and in resolving this, negative behaviour and emotions are addressed. Unfortunately, research doesn’t quite back up this story."
