Objective
[edit | edit source]

Patient-completed questionnaire which gives a subjective percentage score of level of function (disability) in activities of daily living in those rehabilitating from low back pain. Suitable for the English speaking population only.

Intended Population
[edit | edit source]

Acute or chronic low back pain.  Most effective for persistent severe disability[1]

Method of Use[edit | edit source]

Questionnaire examines perceived level of disability in 10 everyday activities of daily living.

The 6 statements are scored from 0 to 5 with the first statement scoring 0 through to the last at 5, e.g.,
Section 1 - Pain intensity
• I have no pain at the moment. Score = 0
• The pain is very mild at the moment. Score = 1
• The pain is moderate at the moment. Score = 2
• The pain is fairly severe at the moment. Score = 3
• The pain is very severe at the moment. Score = 4
• The pain is the worst imaginable at the moment. Score = 5

If more than one box is marked in each section, take the highest score.

The ODI score (index) is calculated as:

For example:

If all 10 sections are completed the score is calculated as follows:

if 16 (total scored) out of 50 (total possible score) x 100 = 32%

If one section is missed (or not applicable) the score is calculated:

If 16 (total scored) / 45 (total possible score) x 100 = 35.5%

Rounding the percentage to a whole number for convenience is suggested.

Evidence[edit | edit source]

Reliability[edit | edit source]

The ODI addresses a broader concept of disability than that directly related to pain intensity[2].
