SCORING NECK DISABILITY INDEX (NDI), THE MODIFIED OSWESTRY
DISABILITY INDEX, AND THE FEAR AVOIDANCE BELIEFS
Scoring the Neck Disability Index or Modified Oswestry Disability Index
1. Assign a score to each section. Each section can be scored from 0-5, based on the
selection chosen by the patient. If the patient marks the first response, assign a score of
0, the next response a 1, the next response a 2, and so on, with the final response being
assigned a score of 5. Below is an example of the section called “Pain Intensity” with
the corresponding score that should be assigned if that response is selected.
Assign score of: Pain Intensity
0 I can tolerate the pain I have without having to use pain
2 The pain is bad but I can manage without having to take pain
4 Pain medication provides me complete relief from pain.
5 Pain medication provides me with moderate relief from pain.
Pain medication provides me with little relief from pain.
Pain medication has not effect on my pain.
2. Add up the individual scores for each section.
3. Divide this result by 50, and report as a percentage (ex. 30/50 = 60%). In the event a
patient does not complete each section adjust the denominator accordingly. For
example, if the patient does not answer the question with respect to “Social Life”, you
would divide by 45 instead of 50. Divide by 40 if they leave 2 sections blank, 35 if
they leave 3 sections blank, and so on. However, it is recommended the clinician
always check to ensure all items are completed to minimize having to adjust the
score. The interpretation of the results become less meaningful when more than 1-2
items are missing.
Scoring the FABQ
The FABQ consists of 2 subscales, which are reflected in the division of the outcome
form into 2 separate sections. The first subscale (items 1-5) is the Physical Activity
subscale (FABQPA), and the second subscale (items 6-16) is the Work subscale
(FABQW). Although we are only interested in the FABQW subscale for the purposes of
classifying patients, all items should be completed. Interestingly, not all items contribute
to the score for each subscale; however the patient should still complete all items as these
items were included when the reliability and validity of the scale was initially established.
Also note that there is no total score where the each subscale score is added as each
subscale exists as a separate entity. The method to score each subscale is outlined below.
(Note: It is extremely important to ensure all items are completed as there is no procedure
to adjust for incomplete items.)
Scoring the Physical Activity subscale (FABQPA)
Sum items 2, 3, 4, and 5 (the score circled by the patient for these items).
Scoring the Work subscale (FABQW)
Sum items 6, 7, 9, 10, 11, 12, and 15. (The items that need to be added are in bold on the form.)
