Psychometric case identification of individuals at risk for developing schizophrenia-spectrum disorders is an important enterprise. Unfortunately, current instruments this purpose are limited. The present studies sought to improve the Schizotypal Personality Questionnaire-Brief (SPQ-Brief), a measure schizotypal traits that has come under recent criticism. In first study, we conducted exploratory factor analysis on SPQ-Brief using Likert-style scoring format in large sample nonclinical...
Social anhedonia has been employed in psychometric high-risk studies to identify putative schizotypes. To date, this research focused almost exclusively on college samples. The current study sought examine the validity of social as an indicator risk for schizophrenia-spectrum disorders within a community sample. Furthermore, we evaluated role other individual difference variables accounting variable clinical severity group including trait affectivity, support, and family environment....
Background Schizotypal traits are considered a phenotypic-indicator of schizotypy, latent personality organization reflecting putative liability for psychosis. To date, no previous study has examined the comparability factorial structures across samples originating from different countries and cultures. The main goal was to evaluate structure reliability Personality Questionnaire (SPQ) scores by amalgamating data studies conducted in 12 21 sites. Method overall sample consisted 27 001...
Technological advances in the assessment and understanding of speech language within domains automatic recognition, natural processing, machine learning present a remarkable opportunity for psychologists to learn more about human thought communication, evaluate variety clinical conditions, predict cognitive psychological states. These innovations can be leveraged automate traditionally time-intensive tasks (e.g., educational assessment), provide information care chatbots), when delivered...
Abstract Facial emotion recognition deficits have been widely investigated in individuals with schizophrenia; however, it remains unclear whether these reflect a trait-like vulnerability to schizophrenia pathology present at risk for the disorder. Although some studies this population, findings mixed. The current study uses well-validated task, relatively large sample, and examines relationship between recognition, symptoms, overall life quality. Eighty-nine psychometrically defined...
Elucidating schizotypal traits is important if we are to understand the various manifestations of psychosis spectrum liability and reliably identify individuals at high risk for psychosis. The present study examined network structures (1) 9 personality domains (2) 74 individual items, (3) explored whether networks differed across gender culture (North America vs China). was conducted in a sample 27001 participants from 12 countries 21 sites (M age = 22.12; SD 6.28; 37.5% males). Schizotypal...
Abstract Objective Negative symptoms and functional outcome have traditionally been assessed using clinical rating scales, which rely on retrospective self-reports several inherent limitations that impact validity. These issues may be addressed with more objective digital phenotyping measures. In the current study, we evaluated psychometric properties of a novel “passive” method: geolocation. Method Participants included outpatients schizophrenia or schizoaffective disorder (SZ: n = 44),...
