The NCCN Distress Thermometer (DT) is a one-item, 11-point Likert scale represented on a visual graphic of a thermometer that ranges from 0 (no distress) to 10 (extreme distress), with which patients indicate their level of distress over the course of the week prior to assessment.

This validated 10 item survey captures a person's self assessment of their global physical and global mental health. The possible score ranges from 0 to 20 points in each case. 0 points represent the patient's most severe physical and/or mental impairment, while 20 points represent the best possible state of health.

This validated 20 item measure has been used extensively in research. Scores consist of a total symptom severity score (from 0 to 80) from four subscales: Re-experiencing (items 1-5 - max score = 20), Avoidance (items 6-7 - max score = 8), Negative alterations in cognition and mood (items 8-14 - max score = 28), and Hyper-arousal (items 15-20 - max score = 24). Higher scores represent higher severity.
