McGill Pain Questionnaire
Evaluates pain based on a self-report on set descriptors of the quality and intensity of pain, to be used on the spot or for long-term monitoring.
Refer to the text below the questionnaire for more information about the McGill Pain index and its usage.
The McGill Pain Questionnaire (also known as the McGill Pain Index) or MPQ is a self-report scale developed by Melzack and Torgerson in 1971, to allow people experiencing significant pain to give their clinician an exact description of the quality and intensity of pain that they are experiencing.
The tool can be used to assess pain on the spot, or monitor it over time, for example in determining the effectiveness of a pain management intervention.
The MPQ consists of 20 sections that group a list of 78 descriptive words. The questionnaire can also be divided into four domains: Sensory (sections 1-10), Affective (sections 11-15), Evaluative (section 16) and Miscellaneous (sections 17-20).
There is an additional question, on a 5 item Likert scale, about present pain intensity.
The sum of points from the 20 sections determines a Pain Rating Index (PRI) and the interpretation states that the higher the score, the greater the perceived pain.

McGill Pain Questionnaire Explained
The McGill Pain Questionnaire (also known as the McGill Pain Index) or MPQ is a self-report scale developed by Melzack and Torgerson in 1971, to allow people experiencing significant pain to give their clinician an exact description of the quality and intensity of pain that they are experiencing.
The tool can be used to assess pain on the spot, or monitor it over time, for example in determining the effectiveness of a pain management intervention, as well as be of use in epidemiological and clinical studies. This is the most widely used measurement tool for multidimensional pain assessment in chronic pain.
The questionnaire can also be divided into four domains: Sensory (sections 1-10), Affective (sections 11-15), Evaluative (section 16) and Miscellaneous (sections 17-20).
Sensory descriptors are used to describe how the pain feels in the present moment at the time of reporting:
- Flickering, Quivering, Pulsing, Throbbing, Beating, Pounding
- Jumping, Flashing, Shooting
- Pricking, Boring, Drilling, Stabbing, Lancinating
- Sharp, Cutting, Lacerating
- Pinching, Pressing, Gnawing, Cramping, Crushing
- Tugging, Pulling, Wrenching
- Hot, Burning, Scalding, Searing
- Tingling, Itchy, Smarting, Stinging
- Dull, Sore, Hurting, Aching, Heavy
- Tender, Taut, Rasping, Splitting
Affective descriptors are used to offer an understanding into how an individual’s pain changes with time:
- Tiring, Exhausting
- Sickening, Suffocating
- Fearful, Frightful, Terrifying
- Punishing, Gruelling, Cruel, Vicious, Killing
- Wretched, Blinding
Evaluative descriptors are used to assess how strong the pain feels:
- Annoying, Troublesome, Miserable, Intense, Unbearable
Miscellaneous descriptors
- Spreading, Radiating, Penetrating, Piercing
- Tight, Numb, Drawing, Squeezing, Tearing
- Cool, Cold, Freezing
- Nagging, Nauseating, Agonizing, Dreadful, Torturing
Present Pain Intensity
No pain (0); Mild (1); Discomforting (2); Distressing (3); Horrible (4); Excruciating (5)
McGill Pain Questionnaire Scores
- Sensory score = sum of answers from 1 to 10
- Affective score = sum of answers from 11 to 15
- Evaluative score = score from question 16
- Miscellaneous score = sum of answers from 17 to 20
- Pain Rating Index (PRI) = sum of answers from 1 to 20
- Present Pain Intensity (PPI) – score from the PPI question
Pain score interpretation: The higher the score, the greater the perceived pain. Should there be any suspicions regarding the patient language proficiency, the test administrator should define the unknown words/concepts.
The use of the MPQ has demonstrated that different pain syndromes/conditions can be consistently described with specific groups of adjectives. The questionnaire has to date been used in over 500 research studies and benefits from 26 different language versions.
The questionnaire has been validated in patients with fibromyalgia, chronic pelvic pain, herniated intervertebral discs, ischemic muscular pain, low back pain, lumbago-sciatica, rheumatic pain or malignancy.
