The McGill Pain Questionnaire is a widely used tool designed to assess and describe the quality and intensity of a person's pain. Developed by Dr. Ronald Melzack in 1975, it consists of a list of words that patients can choose from to express their pain experience. The questionnaire includes sections for pain intensity, sensory qualities, and affective qualities, allowing for a comprehensive evaluation of pain. This questionnaire is beneficial in both clinical and research settings, helping healthcare providers understand a patient's pain more effectively. By using the McGill Pain Questionnaire, practitioners can tailor treatment plans to address the specific pain characteristics reported by patients, improving overall pain management.
