Craske For DSM-V, simple dimensional measures of disorder severity will accompany diagnostic criteria. The current studies examine convergent validity and test-retest reliability of two potential dimensional indicators of worry severity for Generalized Anxiety Disorder (GAD): percent of the day worried and number of worry domains. In study 1, archival data from diagnostic interviews from a community sample of individuals diagnosed with one or more anxiety disorders (n = 233) were used to assess correlations between percent of the day worried and number of worry domains with other measures of worry severity (clinical severity rating (CSR), age of onset, number of comorbid disorders, Penn State Worry Questionnaire (PSWQ)) and DSM-IV criteria (excessiveness, uncontrollability and number of physical symptoms).
