Abstract
Summary: This study presents a French version of the Penn State Worry Questionnaire (PSWQ), the factorial structure of which was evaluated on a nonclinical sample of 668 adults. A confirmatory factor analysis showed that the French PSWQ is a one-dimensional worry instrument. However, the inclusion of method factors was needed to reach a good fit of the model. Method effects appear to be associated with negatively keyed items. Finally, the instrument demonstrated excellent internal consistency and good test-retest reliability.
