Which term describes the belief that catastrophe will occur?

• A. Delusions
• B. Grandiose Delusions
• C. Nihilistic Delusions
• D. Thought Withdrawal

Answer: (C)

Belief that catastrophe will occur is a nihilistic delusion. Nihilistic delusions involve a negation of reality with an expectation of doom, destruction, or nonexistence—ideas that something catastrophic is about to happen or that the world as we know it will end. This theme is distinct from grandiose delusions, which center on inflated importance or power, and from thought withdrawal, which is the belief that thoughts are being removed from the mind. Delusions, in general, is a broad term, but nihilistic delusions specifically capture the sense of impending catastrophe. In clinical settings, these delusions can appear in psychotic disorders and may accompany mood disorders with psychotic features, signaling a need for careful assessment and safety planning.
