Dimensional indicators of generalized anxiety disorder severity for DSM-V

► Simple dimensional measures of disorder severity are needed for GAD in DSM-V. ► Percent of the day worried and number of worry domains were examined for validity and reliability. ► Validity was tested in a clinical sample, and test-retest reliability in a non-clinical sample. ► Both measures displayed good convergent validity with existing measures of worry severity. ► Percent of the day worried had the best reliability compared to number of worry domains and DSM-IV criteria.
