 Assessment Several scales for assessing the presence of clinical anxiety have been validated and are used routinely. These include the Hamilton Anxiety Scale (HAM-A), Hospital Anxiety and Depression Scale (HADS), Generalized Anxiety Disorder Questionnaire-IV (GAD-Q-IV). Regardless f whether they are self-administered, or structured interviews administered by the clinician, they all assess the presence of anxiety symptoms and their severity. They are not adequate for early detection or screening of probable GAD cases and cannot be self-administered by the patient without clinician supervision (Garcia-Campayo et al. 2012)
