 should not be diagnosed by the content of the belief, but by the way in which a belief is held.

    (also called thought diffusion)
  • Delusional perception (i.e. taking a normal sensory perception to mean a bizarre situation such as taking seeing an aeroplane as indicating the patient should be the next president)


The reliability of using first-rank symptoms for the diagnosis of schizophrenia has since been questioned, although the terms might still be used descriptively by mental health professionals who do not use them as diagnostic aids.

A memory device that is frequently used to remember the first rank symptoms
is ABCD: Auditory hallucinations, Broadcasting of thought, Controlled thought (delusions of control), Delusional perception.
