Individuals with schizotypal personality disorder tend to rate higher than do people with other personality disorders on the dimension of:

A) psychoticism.
B) disinhibition.
C) antagonism.
D) detachment.

Individuals with schizotypal personality disorder tend to have perceptual and cognitive distortions similar to those seen in schizophrenia, including odd beliefs, magical thinking, and perceptual disturbances. These features fall under the domain of psychoticism, making option A the correct choice. Disinhibition (B) refers to impulsivity and lack of control over behavior, which is not a core feature of schizotypal personality disorder. Antagonism (C) refers to hostility and oppositional behavior, which is also not a core feature of schizotypal personality disorder. Detachment (D) refers to avoidance of social relationships and emotional coldness, which is a common feature of schizoid personality disorder, but not necessarily schizotypal personality disorder.
