An examination of the factorial structure of the Schizotypal Personality Questionnaire-Brief (SPQ-B) among undergraduate students.
Cognitive-perceptual, interpersonal, and disorganized subscales of the Schizotypal Personality Questionnaire-Brief (SPQ-B), reflecting the three commonly used subscales of the full-version SPQ, have been used in a number of studies. However, the factorial validity of SPQ-B subscales remains to be clarified. Utilizing data from 825 undergraduate students, confirmatory factor analyses involving the 22 items of the SPQ-B were conducted. A significant chi(2) difference test favored the 3-factor over the 1-factor model and fit indices for the 3-factor model were generally satisfactory. However, several of the items may index more than one of the hypothesized factors, so the item-factor separation is not sharp. Thus, more research is needed on the factorial validity of the increasingly used SPQ-B subscales.
