An example of an ASA status classification system is that used by dental professionals. [4] Many include the 'functional limitation' or 'anxiety' to determine classification which is not mentioned in the actual definition but may prove to be beneficial when dealing with certain complex cases.
All of these scores are used to compute an overarching score that indicates a person's anxiety severity. [4] The Hamilton Anxiety Rating scale has been considered a valuable scale for many years, but the ever-changing definition of anxiety, new technology, and new research has had an effect on the scale's perceived usefulness.

Using a cut-off of 8 the GAD-7 has a sensitivity of 92% and specificity of 76% for diagnosis generalized anxiety disorder. The following cut-offs correlate with level of anxiety severity: Score 0-4: Minimal Anxiety; Score 5-9: Mild Anxiety; Score 10-14: Moderate Anxiety; Score greater than 15: Severe Anxiety
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 ...
The YMRS was also designed for completion by nurses at the end of their eight-hour shift on an inpatient unit, observing adult patients. The KMRS has several advantages in comparison: It covers all the symptoms used in current versions of ICD and DSM, it was designed for use with children and teenagers, and it was written and validated as an ...
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.
It has been used in cognitive-behavioral treatments for anxiety disorders (e.g. exposure practices and hierarchy) and for research purposes. There is no hard and fast rule by which a patient can self assign a SUDS rating to his or her disturbance or distress, hence the name subjective. Some guidelines are:
The PANAS for Children (PANAS-C) was developed in an attempt to differentiate the affective expressions of anxiety and depression in children. The tripartite model on which this measure is based suggests that high levels of negative affect is present in those with anxiety and depression, but high levels of positive affect is not shared between the two.
