Abstract
Background
While the Schizotypal Personality Questionnaire (SPQ; Raine, 1991) is an established measure of self-reported schizotypy, the higher-order structure of its ratings has continued to be debated in numerous translations. Here, we examined the psychometric properties of a Romanian translation of the SPQ and assessed associations with quality of life, self-esteem, and satisfaction with life.
Methods
In total, 711 university students (488 women, 223 men) from Romania completed a novel translation of the SPQ online alongside measures of quality of life, self-esteem, and life satisfaction. All participants indicated no immediate family history relating to psychosis.
Results
Using confirmatory factor analysis, we suggest that a 4-dimensional model of SPQ scores had better fit to these data than alternative 3- and 4-factor models. The 4-factor model also demonstrated partial measurement invariance across sex, although sex differences on domain scores were negligible (ηp2 = .01-.02). The 4 SPQ domains were significantly and negatively correlated with all additional measures of quality of life, self-esteem, and satisfaction with life. Further, in predicting scores on these additional measures, the Negative SPQ domain emerged as the strongest predictor, with Paranoid and Disorganised scores also significant predictors.
Discussion
Romanian SPQ scores demonstrated adequate construct and predictive validity vis-à-vis quality of life, satisfaction with life, and self-esteem. Importantly, our findings highlighted the benefit of a Paranoid factor within the SPQ dimensionality, which provides support for a 4-factor conceptualisation of SPQ scores in a hitherto neglected linguistic group.
