“…Dimensional schizotypy is closely related to the categorical diagnosis of schizotypal personality disorder (SPD), and there is high overlap between these two conditions. For example, in a recent study, high dimensional schizotypy was associated with an almost six-fold increase in the likelihood of meeting criteria for SPD (Bolinskey, James et al 2015). In fact, the Schizotypal Personality Questionnaire (SPQ), one of the commonly used assessment instruments to assess dimensional schizotypy, is based on the DSM diagnostic criteria for SPD (Raine, 1991) - which include ideas of reference, magical thinking, unusual perceptual experiences, odd speech, suspiciousness, constricted affect, odd behavior, lack of close friends, and social anxiety (American Psychiatric Association, 2013).…”
