Repetitive behaviors performed to relieve anxiety:

Choice A reason: Compulsions are repetitive physical behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules. These acts are specifically designed to neutralize or prevent anxiety or a dreaded event, though they are not realistically connected. Choice B reason: Phobias are persistent, irrational fears of specific objects, activities, or situations that lead to a compelling desire to avoid the feared stimulus. While phobias generate significant anxiety, they refer to the fear and avoidance rather than the repetitive, ritualistic behaviors performed to mitigate that internal distress. Choice C reason: Intrusive thoughts are the internal, distressing ideas or images that often serve as the trigger for anxiety. They are the cognitive "obsessions" that precede the behavioral "compulsions." They are involuntary and distressing, but they are not the behaviors themselves that the individual uses to find relief. Choice D reason: Delusions are fixed, false beliefs maintained despite evidence to the contrary. They are categorized as thought content abnormalities rather than behavioral rituals. While a delusion might cause anxiety, it is not a repetitive action performed by the patient to provide temporary psychological relief or neutralize a fear.
