Popis: Epistemic beliefs are notoriously difficult to measure with self-report instruments. In this study, the authors used large samples to assess the factor structure and internal consistency of 3 self-report measures of domain-general epistemic beliefs to draw conclusions about the trustworthiness of findings reported in the literature. College students completed the Epistemological Questionnaire (EQ; M. Schommer, 1990; N = 935); the Epistemic Beliefs Inventory (EBI; G. Schraw, L. D. Bendixen, & M. E. Dunkle, 2002; N = 795); and the Epistemological Beliefs Survey (EBS; P. Wood & C. Kardash, 2002; N = 795). Exploratory factor analyses, confirmatory factor analyses, and internal consistency estimates indicated psychometric problems with each of the 3 instruments. The authors discuss challenges in conceptualizing and measuring personal epistemology.
