TLDR
The SPQ subscales and items describing ideas of reference and lack of close interpersonal relationships were found to correlate significantly with TTP, and the co-occurrence of these features doubled the risk of TTP.About:

The Role of Schizotypy in the Study of the Etiology of Schizophrenia Spectrum Disorders
TL;DR: It is suggested that rather than being superseded by genetic factors due to their higher specificity and predictive power for transition to psychosis, schizotypy integrates them as it constitutes a dynamic continuum ranging from personality to psychosis.

Developing Psychosis and Its Risk States Through the Lens of Schizotypy
Martin Debbané,Stephan Eliez,Deborah Myriam Badoud,Philippe Conus,Rahel Flückiger,Frauke Schultze-Lutter +5 more
TL;DR: 18 prospective studies on 15 samples examining the evidence for a link between trait schizotypy and conversion to psychosis in 4 different types of samples are reviewed, underline the value of schizotypesy in high-risk research, but also point to the lack of evidence needed to better define the position of the construct of schzotypy within a developmental psychopathology perspective of emerging psychosis and schizophrenia-spectrum disorders.

Development and psychometric properties of the Multidimensional Schizotypy Scale: A new measure for assessing positive, negative, and disorganized schizotypy
Thomas R. Kwapil,Thomas R. Kwapil,Georgina M. Gross,Paul J. Silvia,Michael L. Raulin,Neus Barrantes-Vidal +5 more
TL;DR: The MSS is based on current conceptual models and taps positive, negative, and disorganized dimensions of schizotypy and appears to provide a promising measure for assessing schizotypesy.

Comparing the factor structure of the Wisconsin Schizotypy Scales and the Schizotypal Personality Questionnaire
TL;DR: This study examined the comparability of the factor structure of 2 leading psychometric measures of schizotypy, finding support for a 2-factor model with positive and negative factors underlying the WSS and the best fit for the SPQ.

The interpersonal theory of psychiatry
TL;DR: In this article, the authors describe how Sullivan traced from early infancy to adulthood the formation of the person, opening the way to a deeper understanding of mental disorders in later life, using a developmental approach to psychiatry.

Structured clinical interview for DSM-IV axis I disorders : SCID-I : clinical version : scoresheet
TL;DR: The SCID-I is an efficient, user-friendly instrument that covers those DSM-IV diagnoses most commonly seen by clinicians and includes the diagnostic criteria for these disorders with corresponding interview questions and provides extensive documentation of the diagnostic process.

Psychosis as a state of aberrant salience: A framework linking biology, phenomenology, and pharmacology in schizophrenia.
TL;DR: A heuristic framework for linking the psychological and biological in psychosis is provided and it is proposed that a dysregulated, hyperdopaminergic state, at a "brain" level of description and analysis, leads to an aberrant assignment of salience to the elements of one's experience, at an "mind" level.
Journal ArticleDOI
The SPQ: A Scale for the Assessment of Schizotypal Personality Based on DSM-III-R Criteria
TL;DR: The SPQ was found to have high sampling validity, high internal reliability, test-retest reliability, convergent validity, and criterion validity, findings which were replicated across samples, and may be useful in screening for schizotypal personality disorder in the general population and also in researching the correlates of individual schizotypesal traits.

Schizotaxia, Schizotypy, Schizophrenia
TL;DR: While I have not until recently begun any systematic research efforts on this baffling disorder, I felt that to share with you some of my thoughts, based though they are upon clinical impressions in the context of selected research by others, might be an acceptable use of this occasion.
