Primary use / Purpose:
The ADDQ is a 4-part self-report questionnaire assessing fearfulness and apprehension/worry, the severity, interference, and distress of the anxiety, as well as specific symptoms (i.e. shortness of breath, irritability).
Background:
The ADDQ was constructed as a screening tool for the presence of clinical fear and anxiety independent of diagnoses, in both clinical and nonclinical populations.
Psychometrics:
Support for the psychometric validity of the ADDQ is presented (Norton & Robinson, 2010).
