The structure of schizotypal personality traits: a cross-national study

Abstract

The results are consistent with the conceptual notion that schizotypal personality is a multifaceted construct and support the validity and utility of SPQ in cross-cultural research. We discuss theoretical and clinical implications of our results for diagnostic systems, psychosis models and cross-national mental health strategies.

Latent profile analysis of psychosis liability in a community‐derived sample of adolescents: Links with mental health difficulties, suicidal ideation, bipolar‐like experiences and psychotic‐like experiences

“…Previous factorial studies have demonstrated that schizotypy is a multidimensional construct in nature, composed basically of three factors (cognitive‐perceptual, interpersonal, and disorganization), phenotypically similar to that found in patients with psychosis (eg, positive, negative and disorganization symptoms) (Fonseca‐Pedrero, Debbané et al, ). Just as schizophrenia is phenotypically heterogeneous, encompassing a broad range of emotional, cognitive, perceptual, social and behavioural functions, schizotypy involves a diverse set of traits from different psychological systems (Cohen, Mohr, Ettinger, Chan, & Park, ).…”

A diagnostic classification version of Schizotypal Personality Questionnaire using diagnostic classification models

“…The SPQ has been demonstrated to have adequate psychometric properties in many studies (e.g., Chen et al, 1997; Cicero, ; Fonseca‐Pedrero et al, ; Raine, ). Furthermore, a cross‐national study, conducted by Fonseca‐Pedrero et al () using a large and multinational sample, also first suggested that the SPQ has good psychometric properties across countries. In order to compose a DC‐SPQ, all of the items were selected from the Chinese‐translated version of the SPQ (Chen et al, 1997) based on the psychometric characteristic.…”

Schizotypal traits and their relation to rejection sensitivity in the general population: Their mediation by quality of life, agreeableness and neuroticism

“…Schizotypy has several possible phenotypic expressions, namely schizotypal traits (at a behavioural level), schizotypal personality disorder, and psychosis (at sub-clinical and clinical levels, respectively) that are inter-related, but not necessarily interchangeable (Lenzenweger, 2010;Linscott et al, in press). According to this definition, schizotypy represents a theoretical construct and aetiological model of psychosis (Fonseca-Pedrero et al, 2018). Most people with schizotypy do not make the transition to psychosis (Kwapil et al, 2012;Rössler et al, 2013).…”

“…People who score highly on the Schizotypal Personality Questionnaire have schizotypal personality disorder (Raine, 1991). Schizotypal traits being on a continuum with the schizophrenia spectrum, could help to detect individuals at risk for psychosis (Ettinger et al, 2014;Fonseca-Pedrero et al, 2018). A further similarity between schizotypy and psychosis is the presence of positive and negative dimensions (Kendler, 1991;Liddle, 1987).…”

“…Positive schizotypy predicts a greater likelihood of having a psychotic disorder, while negative and positive schizotypal traits predict a greater likelihood of schizophrenia-4 spectrum disorders (Kwapil et al, 2013). Social anxiety is another schizotypal dimension denoting an intense fear of being rejected, embarrassed, and humiliated in social and performance situations (American Psychiatric Association, 2000;Fonseca-Pedrero et al, 2018). Social anxiety could contribute to paranoia in psychosis if paranoid beliefs contained beliefs that others will harm you (Green and Phillips, 2004;Lysaker et al, 2010).…”
