Abstract

The Hungarian version of the Penn State Worry Questionnaire (PSWQ) was validated in two studies, using five different samples. Study 1 tested the factor structure and internal consistency of the PSWQ in two undergraduate student samples, comparing the psychometric properties of the paper-pencil and the online versions of the scale. Study 2 assessed construct validity in two undergraduate student samples and in a sample of patients diagnosed with Generalized Anxiety Disorder (GAD) and matched control participants. Our results suggest that the Hungarian PSWQ demonstrates good psychometric properties. We found no difference between the online and the paper-pencil versions of the scale. A factor structure with one general worry factor and two method factors representing wording effects showed the best fit to the data.
