BPI was originally intended to help measure cancer patients pain, but today it is used in cancer related cases as well as non-cancer related cases.
In Pain Interference two dimensions help discover different problems that need to be accessed to accurately treat the patient.
Pain Intensity is measured in four categories: worst, least, on average, and currently, while Pain Interference is measured in 7 categories: mood, work, general activity, walking, relationships, enjoyment of life, and sleep.
The patient rates each of these on a scale from 0–10, 10 being excruciating pain intensity and a complete interference in their life.
