where:
• The question on driving is omitted if the patient did not drive a car when in good health.
neck pain score =
= SUM(points for the first 9 questions)
If the all 9 questions are answered, then
NPQ percentage =
= (neck pain score) / 36 * 100%
If only the first 8 questions are answered, then
NPQ percentage =
= (neck pain score) / 32 * 100%

• minimum score: 0
• maximum score: 36 if all 9 questions answered, 32 if only the first 8
• The percentages range from 0 to 100%.
• The higher the percentage, the greater the disability.
Performance:
• The questionnaire has good short term repeatability and internal consistency.
