The McGill Pain Questionnaire (Short Form) measures a patient’s subjective pain experience by using two dimensions of pain, sensory pain rating index (S-PRI) and affective pain rating index (A-PRI), and a total pain rating index (T-PRI). It was developed at McGill University by Melzack and Torgerson in 1971. The McGill Pain Questionnaire is copywritten by Ronald Melzack - ensure that the necessary licensing is secured before use!
