Pain Disability Index (PDI)

The Pain Disability Index is a tool used for measuring the degree of pain a patient is experiencing. The test is a self-report asking patients to rate how much pain interferes in seven areas of life activity: family/home, recreation, social, occupation, sexual, self-care, life-support, and average. Participants use a 0 (no disability) to 10 (total disability) numeric rating scale. Approximately 5 minutes is required to administer the test.

Reliability and Validity

Evaluation strongly supports the use and reliability of the Pain Disability Index; however, issues dealing with bias and influence on reports have been investigated. Patients had sometimes untruthfully reported their pain to increase their disability. The test-rest reliability of the PDI was .44 and the internal consistency was 0.86 (Cronbach alpha rating), according to studies by Tait, Chibnall, and Krause (1990) using a sample of 444 patients with chronic pain.
