In which of the following disorders are people likely to have a large number of self-imposed rituals?

A) panic disorder
B) conversion disorder
C) multiple personality
D) obsessive-compulsive disorder

People with obsessive-compulsive disorder (OCD) are likely to have a large number of self-imposed rituals, as this is a defining feature of the disorder. These rituals, or compulsions, are often performed in an attempt to alleviate anxiety caused by obsessions (repetitive thoughts or images that are unwanted and distressing). Panic disorder is characterized by recurrent panic attacks, conversion disorder involves the experience of physical symptoms without a medical explanation, and multiple personality (now known as dissociative identity disorder) involves the presence of multiple distinct identities within one individual. While these disorders may involve some level of ritualized behavior or repetition, they are not primarily characterized by self-imposed rituals.
