Discan

The term is a contraction of the words "discretized" and "analog"[1] and is also known as categorical analogue scales.

Its scoring system is a unitary non-transitional scales of severity that may have a maximum 8 or 10.

[2] With the Discan method, four descriptive anchor-levels yield 14 scale-points, or three levels produce ten, representing some of the possible values of intensity of the variable.

[1] The Likert and analog scales—with the implicit assumption about the judgmental process of rating—are considered part of the Discan family.
