A short form of the Worry Domains Questionnaire: construction and factorial validation. Personality and Individual Differences

The Worry Domains Questionnaire (WDQ) (Tallis, Eysenck, & Mathews, 1992) is an in-strument widely used to assess the amount of worry across five domains of everyday con-cern: relationships, lack of confidence, aimless future, work, and financial issues. With 25 items, however, the WDQ is somewhat lengthy. The aim of the present study was therefore to construct a 10-item short form (WDQ-SF). A sample of 1,080 university students com-pleted 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 sample was used to cross-validate the factorial structure of the WDQ-SF by means of confirmatory factor analysis. Like the WDQ, the WDQ-SF displayed high in-ternal consistency (Cronbach's alpha =.88) and a clear five-factor structure. Moreover, the WDQ-SF showed a near-perfect correlation with the WDQ long form (r =.97). Thus, the WDQ-SF represents a reliable and economical alternative to the full 25-item scale
