A comparison of three worry questionnaires.

This paper describes a study comparing three worry questionnaires; The Worry Domains Questionnaire (WDQ), The Penn State Worry Questionnaire (PSWQ), and The Student Worry Scale (SWS). The results suggested that (i) scores on two out of the three questionnaires exhibited sources of variance that were independent of trait anxiety, (ii) content-based questionnaires (the WDQ and SWS) appeared to capture features of task-oriented constructive worrying, whereas the PSWQ did not, and (iii) all three questionnaires indicated that worriers were characterized by an information-seeking, monitoring cognitive style and a tendency to indulge in avoidance coping behaviours. The implications of these findings for the development of a clinically useful diagnostic instrument are discussed.
