M236. AN ASSESSMENT OF THE DIMENSIONALITY OF A ROMANIAN TRANSLATION OF THE SCHIZOTYPAL PERSONALITY QUESTIONNAIRE AND ASSOCIATIONS WITH QUALITY OF LIFE, SELF-ESTEEM, AND LIFE SATISFACTION

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.
