Relationship of pain drawing scores to ratings of pain description and function.

We examined the relationship between pain distribution and measures of self-reported behavioral functioning, pain intensity, frequency, and quality in 51 patients with chronic pain. Results indicate that patients with more distributed pain report their pain as more disruptive to important areas of functioning and also report their pain as more intense and frequent. These results corroborate previous findings and suggest that pain distribution may be used as a useful clinical marker of disability status in chronic pain patients.
