The Worry Domains Questionnaire (WDQ) [Tallis, F., Eysenck M.W., & Mathews,
(1992). A questionnaire for the measurement of nonpathological worry. Pers
onality and Individual Differences, 13, 161-168)] is an instrument widely u
sed to assess the amount of worry across five domains of everyday concern:
relationships, lack of confidence, aimless future, work, and financial issu
es. With 25 items, however, the WDQ is somewhat lengthy. The aim of the pre
sent study was therefore to construct a 10-item short form (WDQ-SF). A samp
le of 1080 university students completed the 25 items of the WDQ. One-half
of the sample was used to construct the WDQ-SF by selecting two appropriate
items from each of the five WDQ domain subscales. The other half of the sa
mple was used to cross-validate the factorial structure of the WDQ-SF by me
ans of confirmatory factor analysis. Like the WDQ, the WDQ-SF displayed hig
h internal consistency (Cronbach's alpha= 0.88) and a clear five-factor str
ucture. Moreover, the WDQ-SF showed a near-perfect correlation with the WDQ
long form (r = 0.97). Thus, the WDQ-SF represents a reliable and economica
l alternative to the full 25-item scale. (C) 2001 Elsevier Science Ltd. All
