Background

A pervasive pattern of social and interpersonal deficits marked by acute discomfort with, and reduced capacity for, close relationships as well as by cognitive or perceptual distortions and eccentricities of behavior

Clinical Features

  • Five (or more) of the following criteria, beginning in early adulthood and present in a variety of contexts:[1]
    • Ideas of reference (excluding delusions of reference).
    • Odd beliefs or magical thinking that influences behavior and is inconsistent with subcultural norms (e.g., superstitiousness, belief in clairvoyance, telepathy, or “sixth sense”: in children and adolescents, bizarre fantasies or preoccupations).
    • Unusual perceptual experiences, including bodily illusions.
    • Odd thinking and speech (e.g., vague, circumstantial, metaphorical, overelaborate, or stereotyped).
    • Suspiciousness or paranoid ideation.
    • Inappropriate or constricted affect.
    • Behavior or appearance that is odd, eccentric, or peculiar.
    • Lack of close friends or confidants other than first-degree relatives.
    • Excessive social anxiety that does not diminish with familiarity and tends to be as­sociated with paranoid fears rather than negative judgments about self.
  • Does not occur exclusively during the course of schizophrenia, a bipolar disorder or depressive disorder with psychotic features, another psychotic disorder, or autism spectrum disorder
