A '''Subjective Units of Distress Scale''' ('''SUDS''' - also called a '''Subjective Units of Disturbance Scale''') is a scale of 0 to 10 for measuring the [[subjectivity|subjective]] intensity of disturbance or distress currently experienced by an individual. The individual self assesses where they are on the scale. The SUDS may be used as a [[Benchmarking|benchmark]] for a professional or observer to evaluate the progress of treatment. In desensitization-based therapies, such as those listed below, the patients' regular self assessments enable them to guide the clinician repeatedly as part of the therapeutic dialog.
