The Schizotypal Presentation

When unusual beliefs, interpersonal distance, suspiciousness, perceptual changes, and eccentric behaviour appear in the consulting room, recognising the symptoms is only the beginning. The harder task is determining what they mean. The Schizotypal Presentation gives clinicians a structured way to assess presentations that sit near the boundary of personality pathology and psychosis. It examines schizotypal personality disorder, schizotypal disorder, dimensional schizotypy, psychosis risk, autism, OCD, trauma, dissociation, substance-related presentations, culture, and other important differentials. Five practical frameworks organise the work: PRESENT for formulation, ANCHOR for differential diagnosis, Baseline-Change-Threshold for psychosis monitoring, CLEAR for clinical interviewing, and Evidence-Calibrated Treatment Planning. Designed for psychologists, psychiatrists, psychotherapists, counsellors, nurses, social workers, and trainees, this handbook helps clinicians reason carefully when the diagnosis is uncertain, the evidence is limited, and the next clinical decision matters.
