That read like a bad infomercial.
And a nasty one as well, with continuous barbs about how patient's health is basically dependant on their motivation, choice and management skills.
Chalder reads like a very abusive person. (Cruel too, with how amused she was at certain things.) It was also quite malicious how she said:
But obviously with all CBT everything is negotiated with a therapist, so nothing is imposed upon anybody unless they decide that that’s what they want for themselves.
She left out the bit where “cognitive restructuring”, influencing the patient’s thoughts and beliefs, is an active ingredient of the process.
And also the part that "negotiation with the patient" is a core part of the CBT , every course starts with influencing the patient into cooperating with the programme: they purposefully instruct the therapist how to gain patient’s trust with deceitful manipulation so they can be gaslit into doing what the therapist wants them to do. They first need to talk along with the patient, acting like they take them seriously, so they can then later abuse them into continuing activity even when their symptoms worsen and call the notion that they are still ill when they get symptoms from activity a “distortion of reality”.
And next to that obvious omission, it was also another nasty allusion towards the continuous theme in the interview of improvement being a choice, by saying that people should decide of they “want that for themselves”.
