The specifier for bizarre type delusions provides continuity with which DSM edition?

• A. DSM-III
• B. DSM-III-R
• C. DSM-4
• D. DSM-5

Answer: (C)

Bizarre delusions are beliefs that are clearly implausible and not understandable within the person’s culture—things that could not realistically happen and don’t fit ordinary experience. This level of delusion quality was a formal specifier used in DSM-IV to describe certain schizophrenia-spectrum presentations, helping clinicians note when delusions were of the most unusual, implausible kind. In DSM-5, that explicit label was removed as a separate specifier, with clinicians focusing more on the overall delusional content and other specifiers rather than labeling a delusion as “bizarre.” That shift means the specific continuity of having a bizarre delusions specifier stops with DSM-IV. So, the use of this descriptor aligns with the DSM edition that maintained it, which is DSM-4.
