| Résumé : | We assessed the effect of invalid responding on factor structure and on scores of schizotypy through the factor analysis of the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a sample of 580 Romanian students using 3 validity items and 5 social desirability items. We examined the factor structure of the SPQ-B, we compared the mean SPQ-B scores between reliable and unreliable responders and between high vs. low social desirability responders, and we re-run the factor analysis restricting the sample to the reliable or low social desirability responders. Factor analysis resulted in a 3-factor solution: Cognitive-perceptual, Interpersonal and Disorganized dimensions. Unreliable responders had lower scores of positive, negative and total schizotypy. Subjects with high social desirability scores had lower scores of disorganized schizotypy. Factor analyses in the samples of ?good? responders showed minor differences in reliable responders, whereas, after taking into account the effect of social desirability, 2 items correctly loaded on expected dimensions. Random responding and social desirability could influence scores of schizotypy and factor structure. Simple methods could be used to identify invalid responses. The effect of social desirability could be linked to the phrasing of items. [Résumé d'auteur] |
