Abstract

The reliability and validity of the Penn State Worry Questionnaire (PSWQ) and the Worry Domains Questionnaire (WDQ) were examined with self-ratings from a non-clinical sample of 148 students in a test-retest design across four weeks. Ratings from three well-acquainted peers were also obtained. With internal consistencies and test-retest correlations of at least 0.85, the present study confirmed the high reliability of the questionnaires. Moreover, both measures demonstrated substantial convergent validity: Average agreement among peers was 0.42 (PSWQ) and 0.47 (WDQ) and aggregated self-peer agreement was 0.55 (PSWQ) and 0.49 (WDQ). Self-peer agreement was not biased by social desirability. These findings challenge views that worry is an unreliable and unobservable phenomenon.
