AI Article Synopsis
- - The study investigates how schizotypal traits, which can indicate vulnerability to psychotic disorders, differ across sex, age, and countries, using data from 27,001 participants aged roughly 22 years.
- - Results show that females tend to score higher on positive aspects of schizotypal traits, while males score higher on disorganization; also, younger individuals exhibit a decrease in positive traits.
- - The variations in schizotypal traits across different demographics and countries suggest a complex relationship similar to patterns found in psychotic patients, offering new avenues for research in mental health.
Article Abstract
Background: Schizotypal traits are expressions of underlying vulnerability to psychotic disorders which have a potential impact on mental health status, neurocognition, quality of life, and daily functioning. To date, little research has examined epidemiologic landscape of schizotypal traits at the cross-national level. Our aim was to study the expression of schizotypal traits by sex, age, and country in a combined sample gathered from 12 countries.
Methods: A total of 27,001 participants completed the Schizotypal Personality Questionnaire (SPQ). The mean age of participants was 22.12 (SD=6.28); 37.5% (n=10,126) were males.
Results: Schizotypal traits varied according to sex, age, and country. Females scored higher than males in the positive dimension, whereas males scored higher in the disorganization dimension. By age, a significant decrease in the positive schizotypal traits was observed. Epidemiological expression of schizotypal traits varied by country. Moreover, several interactions by sex, age, and country were found.
Conclusions: This pattern is similar to those found in patients with psychosis and psychotic-like experiences. These findings provide new insights and the opportunity to explore the phenotypic expression of schizotypal traits at cross-national level.

Background: The etiology of schizophrenia involves both biological and environmental risk factors. Studying childhood trauma in disorders along the schizophrenia spectrum, including schizotypal personality disorder (SPD), can inform early risk and protective factors for psychosis. However, no study has directly compared childhood trauma between SPD and schizophrenia.

Introduction: Evidence highlights the importance of social isolation as a critical yet underserved treatment target for individuals managing psychosis. Schizotypal traits represent a useful model of psychosis, facilitating the assessment of contributors to social isolation without the confounds associated with schizophrenia. This study utilised structural equation modelling to examine the unique predictive capacity of schizotypal traits for subjective and objective indices of social isolation.

Background: Self-disorders constitute a core feature of the schizophrenia spectrum, including early stages such as first-episode psychosis (FEP). These disorders impact the minimal Self, or bodily self-consciousness, which refers to the basic, pre-reflective sense of embodied experience. The minimal Self is intrinsically linked to episodic memory, which captures specific past experiences of the Self.
