Psychometric Properties of the Penn State Worry Questionnaire for Children in a Large Clinical Sample

The Penn State Worry Questionnaire for Children (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997 ) is a 14-item self-report measure of worry in children and adolescents.

Description
Summary:The Penn State Worry Questionnaire for Children (PSWQ-C; Chorpita, Tracey, Brown, Collica, & Barlow, 1997 ) is a 14-item self-report measure of worry in children and adolescents. Although the PSWQ-C has demonstrated favorable psychometric properties in small clinical and large community samples, this study represents the first psychometric evaluation of the PSWQ-C in a large clinical sample (N = 491). Factor analysis indicated a two-factor structure, in contrast to all previously published findings on the measure. The PSWQ-C demonstrated favorable psychometric properties in this sample, including high internal consistency, high convergent validity with related constructs, and acceptable discriminative validity between diagnostic categories. The performance of the 3 reverse-scored items was closely examined, and results indicated retaining all 14 items.
