AB  - A model of anxiety that emphasizes a single common pathology across diagnostic 
      categories is gaining support and influencing nosological and treatment 
      approaches of anxiety disorders. As research in this area continues to grow, a 
      need exists for an assessment tool of the theorized single anxiety pathology that 
      is unbiased toward any particular anxiety diagnosis. The Anxiety Disorder 
      Diagnostic Questionnaire (ADDQ) was developed as a screening tool for the 
      presence of clinical fear and anxiety irrespective of diagnoses. It is a brief 
      four-section index developed to assess fear, anxiety/worry, escape/avoidance 
      behaviors, physiological symptoms, and associated distress and interference. The 
      ADDQ was tested for reliability and validity in two samples: 146 undergraduate 
      students who were given the ADDQ along with a variety of other commonly-used 
      measures of anxiety and 94 outpatients representing a mix of diagnoses (28.2% 
      panic disorder with or without agoraphobia, 44.6% social anxiety disorder, 20.7% 
      generalized anxiety disorder, 3.3% anxiety disorder not otherwise specified, 2.1% 
      obsessive-compulsive disorder, and 1.1% posttraumatic stress disorder). Internal 
      consistency of the instrument was strong, and a one- or two-factor solution was 
      found to be the best fit to the data. Convergent and discriminant validity was 
      also demonstrated. Data from those clinical participants who completed a 
      manualized cognitive-behavioral treatment program indicated a very strong 
      concordance between change on the ADDQ and change in clinician severity ratings 
      from a structured diagnostic interview. The findings offer support for the 
      psychometric validity of the ADDQ in both clinical and nonclinical populations.
