She is not a psychiatrist, she is a consultant forensic psychologist
Forensic psychology is not regarded highly by most actual scientists. It has no credibility and it should be self evident to anyone that personality traits and/or personality disorders cannot be diagnosed using such nonsense.
Paul Britton was perhaps the "forensic psychologist" that made the subject seem as if it was a new tool in crimefighting. The TV series "Cracker" was based on Paul Britton and it was seen by many as credible.
What followed was the Colin Stagg debacle and the aftermath of that including disciplinary and misconduct hearings.
Most people then realised that clinical psychology is a load of old bollocks and learnt to lend the pronouncements of forensic psychologists the same level of credibility usually reserved for Tarot card readers.
