Abstract

Schizotypal personality disorder is characterized by a constellation of traits that fall into three main clusters: cognitive-perceptual disturbances, interpersonal disturbances, and disorganized, eccentric behavior. Although long described under a variety of names by researchers, this constellation of traits was given its current name in 1980 with the publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III; American Psychiatric Association, 1980). Prior to that, researchers referred to the interpersonal and disorganized features of schizotypy as “borderline schizophrenia” in an attempt to characterize those clinical features seen in relatives of individuals with schizophrenia. According to the most recent revision of the DSM, the DSM-IV-TR (American Psychiatric Association, 2000), the disorder consists of a pervasive pattern of social and interpersonal deficits characterized by profound discomfort with, and decreased capacity for, close relationships, in addition to odd behaviors and cognitive and/or perceptual distortions. This pattern begins by early adulthood and occurs in various contexts.
