Book description

This book is devoted to schizotypal personality. It provides a comprehensive overview of our knowledge from some of the world's leading researchers in the field, and includes reviews of genetics, neurodevelopment, assessment, psychophysiology, neuropsychology and brain imaging. Central themes are the exploration of categorical and dimensional approaches to the understanding of schizotypal disorder and its relationship to schizophrenia. Valuable introductory and concluding chapters set in context the sometimes divergent opinions and findings presented by the book's contributors and there are reviews of methodological issues and assessment schedules for the benefit of researchers in the field. In setting out to answer, from phenomenological, psychological and neurobiological perspectives, the fundamental question 'What is schizotypal disorder?' and to develop coherent etiological models, this book will serve as an authoritative resource for clinicians and researchers interested in this major personality disorder.

Reviews

‘… it is a valuable resource not only for researchers new to the area but also for those who want a sophisticated overview of both classic findings and the latest biological and methodological efforts … An encyclopedic subject index and the inclusion of a name index also make this an extremely useful reference work … an excellent book … The editors express hope that this book will stimulate researchers to devote ‘even more time and resources to pursuing the causes and prevention of this enigmatic disorder’. It is hard to imagine a stimulus more likely to do so.’

David A. Smith Source: Clinical Psychology Review

‘… a comprehensive introduction to the field of schizotypal personality … it encompasses what is known about SPD from a biological/medical perspective … it also covers some interesting psychological phenomena … I strongly recommend the book.’

  • 18 - Schizotypal personality: synthesis and future directions
    pp 429-460
  • View abstract

    Summary

    This chapter attempts a broad survey of current scientific inquiry into schizotypal personality and provides directions for future research. The consensual definition of schizotypy can be found in the DSM-III-R, and is relatively unchanged in the DSM-IV. The DSM defines schizotypy as an Axis II personality disorder, which means that the symptoms must be present by early adulthood and must be enduring and persistent across situations and circumstances. The studies using DSM based assessments of schizotypal personality disorder (SPD) have the advantage of sampling a wide range of symptoms thought to be related to factors of cognitive aberrations, interpersonal deficits, and disorganized behavior. The only direct empirical method developed specifically to test the taxonicity of schizotypy is statistical modeling, using Meehl's MAXCOV-HITMAX procedure. The first major biological approach to the definition of schizotypy comes from genetics studies.
  • Semistructured interviews for the measurement of schizotypal personality

    Summary

    The structured clinical interview for DSM-III personality disorders (SIDP) was the first semi-structured interview schedule developed to test and improve DSM-III Axis II validity and reliability. The SIDP-R is the revised edition for DSM-III-R. Both versions of this interview have been tested for reliability and validity, as well as presence and comorbidity of Axis II disorders. The validity of the SIDP has also been tested in a number of studies, usually in terms of concurrent/convergent validity with self-report questionnaires. The schedule for schizotypal personalities (SSP) provides information on SPD and achieves high reliability; however, it does not allow for determination of comorbidity with other Axis II disorders. One important feature is that the self-report measures of the schizotypal signs have been validated against clinicians' observation. The SSP also demonstrated strength specifically in the population it was designed on, that is relatives of schizophrenics, who constitute an important research group.
