Confirmatory factor analysis of the SA-45 Questionnaire in a Mexi-can sample.

Abstract

The aim of this work was to examine the factor structure, reliability and normative data of the Symptom Assessment-45 Questionnaire (SA-45) in a Mexican sample of undergraduates. As predicted, confirmatory factor analyses indicated that a multidimensional 9-factor model provided a good fit for the SA-45. Data on reliability (internal consistency) show the SA-45 to have sound psychometric properties. Normative data suggest that women scored higher than men on all scales except psychoticism. Overall, the study provides consistent cross-cultural support for reliability and validity of the questionnaire.
