title: Reliability and validity of the Korean version of the Penn State Worry Questionnaire in primary school children.
abstract: Worry is a generalized psychological phenomenon seen among most people. When worry is excessive and nearly uncontrollable, people usually suffer psychological pain. The Penn State Worry Questionnaire for Children (PSWQ-C) was developed to measure worry objectively. It comprises 14 items for measuring excessive, generalized, and uncontrollable worry in children. This study, conducted with a large group of elementary children (3rd through 6th graders, ages 8-12 yr; N=973), investigated the reliability and validity of the Korean version of the Penn State Worry Questionnaire for Children (PSWQ-CK). The PSWQ-CK showed high reliability by test-retest and also excellent internal consistency results. To examine the validity of the PSWQ-CK, we calculated its correlation with the Revised Children's Manifest Anxiety Scale (RCMAS). The PSWQ-CK had a higher correlation with the worry/oversensitivity factor than with other subscales of the RCMAS, and it showed no correlation with the lie factor. When 3 reversed PSWQ-CK items were eliminated, the instrument showed higher internal consistency. However, this did not improve its correlation with other anxiety-measuring tools. In conclusion, the PSWQ-CK's reliability and validity were satisfactory, and it is a useful tool for objectively measuring the worry of Korean children of this age group.
