| Description | Objectives. The aim of the present study was to adapt the Schizotypal Personality Questionnaire (SPQ), one of the most widely used methods for the assessment of schizotypy, into the Slovak language and investigate its basic psychometric properties (reliability, latent structure, gender differences, and measurement invariance) in healthy volunteers. Sample and setting. The Slovak version of the questionnaire (SPQ-SK) was completed by 267 responders (120 men and 147 women) with a mean age of 25.3 years (SD = 5.5). SPQ includes 74 binary items arranged into 9 subscales. Hypotheses. Latent structure of two concurrent models, a three-factor and a four-factor model were tested. Statistical analysis. Gender differences were assessed by Welch t-test. Internal consistency was assessed using Cronbach’s alpha and ordinal alpha. Confirmatory factor analysis (CFA) was calculated using the maximum likelihood method. chi-square-test, CFI, RMSEA, SRMR, AIC and BIC were used to evaluate and compare the respective models. Measurement invariance was assessed by chi-square and CFI differences. Results. SPQ-SK showed an acceptable internal consistency. On average, men scored higher in the dimensions Odd or Eccentric Behavior, No Close Friends, and Constricted Affect, whereas women scored higher on Excessive Social Anxiety and Magical Thinking. CFA indicated that a modified three-factor structure represented the best model for SPQ-SK. This model also showed configural invariance and weak measurement invariance. However, strong and strict invariance was only partially supported. Study limitations. The research sample consisted of healthy individuals. Further investigations are needed to determine clinically relevant scores. |
