title: The Penn State Worry Questionnaire: psychometric properties of the Korean version.
abstract: The factor structure and concurrent validity of the Penn State Worry Questionnaire (PSWQ) were examined in two college student samples in Korea. We demonstrated method effects due to the inclusion of negatively keyed items. Confirmatory factor analyses supported the single-factor model with method factor. This indicates that the Korean version of the PSWQ (K-PSWQ) can be contaminated by method effects and response patterns are different between positively worded and reverse-scored items. Thus, the relevance of negatively worded items in the K-PSWQ is questioned.
