In a sample of 75 women recruited from the community, we measured trauma/maltreatment history and symptoms of schizotypal personality disorder, using both questionnaire and interview measures. As hypothesized, individuals with histories of trauma/maltreatment had elevated levels of schizotypal symptoms. Among types of trauma/maltreatment, reported childhood neglect was especially strongly assoc...

background & aim: co-morbidity with schizotypal personality in patients with obsessive-compulsive disorder (ocd) has been widely reported to be associated with poor treatment response. studies have repeatedly revealed a positive and a negative dimension for schizotypy. the primary aim of the present study was to explore if all or only certain features of schizotypy are predictive for therapy ou...

Previous single studies have found inconsistent results on sex differences in positive schizotypy, women scoring mainly higher than men, whereas in negative schizotypy studies have often found that men score higher than women. However, information on the overall effect is unknown. In this study, meta-analytic methods were used to estimate sex differences in Wisconsin Schizotypy Scales developed...

Social Disorganisation (SD) is a shared autistic and schizotypal phenotype that is present in the subclinical population. Auditory processing deficits, particularly in mismatch negativity/field (MMN/F) have been reported across both spectrum disorders. This study investigates differences in MMN/F cortical spatio-temporal source activity between higher and lower quintiles of the SD spectrum. Six...

Negative schizotypal traits may be related to anhedonia and/or amotivation; however it is unclear which of these symptoms is related to negative schizotypy to a greater extent. Moreover, the impact of schizotypal traits on overall subjective well-being remains uncertain. The present study examined these two questions in a non-clinical sample assessed for schizotypal traits (n = 138). Schizotypa...

OBJECTIVE Schizotypal personality traits are associated with schizophrenia spectrum disorders, and individuals with schizophrenia spectrum disorders demonstrate increased dopamine transmission in the striatum. The authors sought to determine whether individual differences in normal variation in schizotypal traits are correlated with dopamine transmission in the striatum and in extrastriatal bra...

OBJECTIVE This overview focuses on neurobiological abnormalities found in subjects with schizotypal personality disorder, the prototype of the schizophrenia spectrum disorders, and chronic schizophrenia in the context of common vulnerabilities shared by schizotypal personality disorder and schizophrenia, as well as the factors that protect against the severe cognitive/social deficits and frank ...

BACKGROUND Schizotypal personality traits are associated with schizophrenia spectrum disorders, stating that schizotypal traits may represent a "prodrome" or other developmental precursor of schizophrenia. Genetic and environmental factors both play importanxt roles in the development of schizotypal traits. Different levels of schizotypal traits across regions may be indicative of similar diffe...

BACKGROUND Research is scarce with regard to the role of psychotic and schizotypal symptoms in treatment of obsessive-compulsive disorder (OCD). The aim of the current study was to investigate the occurrence and specificity of psychotic and schizotypal symptoms among non-psychotic OCD patients, and to examine whether such symptoms was associated with response to exposure and response prevention...
