AI Article Synopsis
- A study was conducted to measure schizotypal personality traits in Swedish-speaking populations and validate the Swedish version of the Schizotypal Personality Questionnaire-Brief (SPQ-B) due to the absence of Scandinavian data in previous research.
- The comparison involved 50 psychiatric patients and 202 control participants, focusing on the psychometric properties such as internal consistency and test-retest reliability of the SPQ-B.
- Results indicated that the Swedish SPQ-B is reliable, can successfully distinguish between psychiatric patients and controls, and shows similarity to findings in international samples, making it a useful tool for assessing schizotypal traits.
Article Abstract
Recently, schizotypal personality traits were measured in a multinational sample recruited from 14 countries, however no Scandinavian cohort was included. The aim of this study was, therefore, to measure schizotypal personality traits in Swedish-speaking populations, with and without psychiatric disorders, and to investigate the psychometric properties of the Swedish version of the Schizotypal Personality Questionnaire-Brief (SPQ-B). The SPQ-B results from 50 psychiatric patients were compared to controls ( = 202). An additional sample of 25 controls completed the full SPQ twice and we calculated test-retest reliability for SPQ and SPQ-B. We estimated the internal consistency for SPQ-B and SPQ-B factors with omega. We compared the results of SPQ-B ( and ) in patient and control groups to corresponding results worldwide. We found similarity between our SPQ-B scores and those from other published samples. SPQ-B showed good internal consistency and acceptable test-retest correlations. The results indicate that the Swedish version of the instrument is valid and can differentiate psychiatric cohorts from non-psychiatric controls. The Swedish version of the SPQ-B exhibit good psychometric properties and is useful for assessing schizotypal traits in clinical and non-clinical populations.

Objective: The present study aimed to examine facial emotion recognition in a sample from the general population with elevated schizotypal traits, as defined by the four-factor model of schizotypy, and the association of facial emotion recognition and the schizotypal dimensions with psychological well-being.
Method: Two hundred and thirty-eight participants were allocated into four schizotypal groups and one control group. Following a cross-sectional study design, facial emotion recognition was assessed with a computerized task that included images from the Radboud Faces Database, schizotypal traits were measured with the Schizotypal Personality Questionnaire, and psychological well-being was evaluated with the Flourishing scale.

Background: Schizotypy refers to a personality type characterized by behavioral and cognitive abnormalities similar in nature but less severe than those of schizophrenia. Schizotypy often progresses to schizophrenia, so identifying risk factors may facilitate early schizophrenia diagnosis and improve treatment. Psychological distress may be associated with schizotypy, highlighting its importance.

Background: Impairments in theory of mind (ToM) are highly prevalent among individuals with schizophrenia, resulting in substantial functional deficits. However, research on impairments in individuals with schizotypy has yielded inconsistent findings, with some studies finding ToM deficits in overall schizotypy, other studies finding ToM deficits in only specific schizotypy dimensions, and yet other studies finding no ToM deficits at all. One potential key factor that may account for this discrepancy is the use of schizotypy measures that do not adequately measure specific schizotypy dimensions.
