Evidence suggests that the structure of psychosisproneness in the general population may involve three distinct related dimensions. Therefore we conducted a study, using a wider range of measures, to explore the factorial structure of schizotypy assessed by a mixed self-report Schizotypal Traits Questionnaire (mSTQ) in young French healthy individuals. Raine’s Schizotypal Personality Questionna...

Youth with an extra X chromosome (47, XXY & 47, XXX) display higher levels of schizotypal symptoms and social anxiety as compared to typically developing youth. It is likely that the extra X chromosome group is at-risk for clinical levels of schizotypy and social anxiety. Hence, this study investigated how schizotypal and social anxiety symptoms are related and mechanisms that may explain t...

OBJECTIVE A cavum between the septi pellucidi may reflect neurodevelopmental anomalies in midline structures of the brain. The authors examined cavum septi pellucidi in subjects with schizophrenia, affective disorder, and schizotypal personality disorder and in normal subjects. METHOD Thirty schizophrenic patients (15 chronic, 15 first-episode), 16 patients with affective disorder (first-epis...

a r t i c l e i n f o Keywords: Autistic-like traits Diametrical model Impulsivity Life history strategy Schizotypal traits Sexual selection Sociosexuality According to recent theoretical models, autistic-like and schizotypal traits can be regarded as opposite sides of a single continuum of variation in personality and cognition, and may be diametrically associated with individual differences i...

Background: Flow experience is thought to enhance health-related quality of life by mitigating stress and providing a sense of achievement. The associations between flow experience and subclinical psychiatric anomalies, such as schizotypal personality traits and paranoid ideation, have not been examined. Objectives: This study aimed to evaluate the associations between flow experience and subcl...

Schizotypal personality features and certain neurocognitive deficits have been shown to aggregate in the relatives of schizophrenic patients, supporting the view that both are likely to reflect genetic contributions to liability to schizophrenia. Within the relatives of schizophrenic patients, however, the interrelationships between these potential indicators of liability to schizophrenia are n...

Attentional-interference using emotional Stroop tasks (ESTs) is greater among individuals in the general population with positive (versus negative) schizotypal traits; specifically in response to negatively (versus positively) valenced words, potentially capturing threat-sensitivity. Variability in attentional-interference as a function of subcategories of negatively valenced words (and in rela...

Behavioral and cognitive dysfunction, particularly social and communication impairments, are shared between autism and schizophrenia spectrum disorders, while evidence for a diametric autism-positive schizophrenia symptom profile is inconsistent. We investigated the shared phenotype at a personality trait level, particularly its resemblance to schizoid personality disorder, as well as different...

BACKGROUND The schizotypal personality disorder is considered as a marker of schizophrenia proneness. The schizotypal personality questionnaire (SPQ) is an instrument to help to the diagnosis of schizotypal personality disorder extensively studied in the literature. aim: To assess psychometric properties (reliability and factor structure) of the Arabic version of the SPQ in a sample of Tunisian...
