What are the scores for the disability index?
The NDI has become a standard instrument for measuring self-rated disability due to neck pain and is used by both clinicians and researchers. Each of the 10 items scores from 0 to 5. The maximum score is 50. The obtained score can be multiplied by two to produce a percentage score.
How to calculate disability index?
In our original publication we suggested that a score of 0% to 20% represented minimal disability; 20% to 40%, moderate disability; 40% to 60%, severe disability; 60% to 80%, crippled. We felt scores of 80% to 100% reflected either an exaggerated response or the respondent was almost certainly bedbound.
How is the neck index scored?
The 8 scores of the 8 sections are summed and divided by 8. The result is the DI or FDI, the disability index or functional disability index. In the event that one section is not completed by a subject then the summed score would be divided by 7.
