The McGill Pain Questionnaire

A Comprehensive Pain Assessment Tool

The McGill Pain Questionnaire (MPQ) is a widely used self-reporting measure of pain intensity, quality, and impact. Developed in the 1970s, the MPQ has become a cornerstone of pain assessment in clinical and research settings.

Measuring Pain Intensity and Quality

The MPQ consists of two main sections: * Pain Intensity Index: Measures the severity of pain using a 0-10 numerical rating scale. * Pain Descriptive Index: Includes a list of 78 pain descriptors organized into 20 subclasses, such as "throbbing," "burning," and "aching." Patients select the descriptors that best describe their pain.

Applications in Pain Management

The MPQ provides valuable information for pain management decision-making: * Diagnosis: Helps clinicians differentiate between different types of pain and identify underlying conditions. * Treatment Monitoring: Tracks changes in pain intensity and quality over time, allowing for adjustments in treatment plans. * Research: Facilitates the study of pain mechanisms, prevalence, and treatment outcomes.

Validation and Reliability

The MPQ has undergone extensive validation and reliability testing. Studies have shown that it is: * Valid: Correlates well with other pain assessment methods and measures pain intensity accurately. * Reliable: Produces consistent results over time and across different raters. * Comprehensive: Captures the multidimensional nature of pain, providing a rich description of the patient's experience.

Conclusion

The McGill Pain Questionnaire is a powerful tool for assessing pain intensity, quality, and impact. Its validity, reliability, and comprehensiveness make it an indispensable instrument in the field of pain management. By providing clinicians and researchers with a detailed understanding of patients' pain experiences, the MPQ facilitates accurate diagnosis, effective treatment, and improved patient outcomes.
