Confirmatory factor analysis of the Fear Questionnaire in injured workers with chronic pain.

In an effort to extend the validity of the Fear Questionnaire (FQ) in a sample of patients with high levels of blood/injury phobia, the FQ responses of 255 injured workers with chronic pain were subjected to confirmatory factor analysis. Results indicated that an intercorrelated three-factor model of the FQ provided a better fit to the data than unidimensional, two-factor, hierarchical three-factor, or categorical three-factor models. These findings provide further support for the factorial validity of the FQ and the corresponding multidimensional theory of fear.
