A number of researchers have explored HADS data to establish the cut-off points for caseness of anxiety or depression. Bjelland et al (2002) [3] through a literature review of a large number of studies identified a cut-off point of 8/21 for anxiety or depression. For anxiety (HADS-A) this gave a specificity of 0.78 and a sensitivity of 0.9.

Aaron T. Beck et al. (1988) combined three separate anxiety questionnaires, with 86 original items, to derive the BAI: the Anxiety Checklist, the Physician's Desk Reference Checklist, and the Situational Anxiety Checklist. [2] The BAI is used for measuring the severity of anxiety in adolescents and adults ages 17 and older.
The GAD-7 has a sensitivity of 57-94% and a specificity of 82-88% in the diagnosis of general anxiety disorder. [7] All screening questionnaires, if positive, should be followed by clinical interview including assessment of impairment and distress, avoidance behaviors, symptom history and persistence to definitively diagnose an anxiety disorder ...
The Screen for Child Anxiety Related Emotional Disorders (SCARED) is a self-report screening questionnaire for anxiety disorders developed in 1997. [1] The SCARED is intended for youth, 9–18 years old, [1] and their parents to complete in about 10 minutes. [2] It can discriminate between depression and anxiety, as well as among distinct ...
State anxiety (S-anxiety) can be defined as fear, nervousness, discomfort, etc. and the arousal of the autonomic nervous system induced by different situations that are perceived as dangerous. This type of anxiety refers more to how a person is feeling at the time of a perceived threat and is considered temporary.
The Zung Self-Rating Anxiety Scale (SAS) was designed by William W. K. Zung M.D. (1929–1992) a professor of psychiatry from Duke University, to quantify a patient's level of anxiety. [ 1 ] [ 2 ] The SAS is a 20-item self-report assessment device built to measure anxiety levels, based on scoring in 4 groups of manifestations: cognitive ...
