Objective
[edit | edit source]
The Nijmegen Questionnaire (NQ) gives a broad view of symptoms associated with dysfunctional breathing patterns. The Nijmegen Questionnaire was introduced over 30 years ago as a screening tool to detect patients with hyperventilation complaints that could benefit from breathing regulation through capnographic feedback
Intended Population
[edit | edit source]
Mostly used for people with hyperventilation syndrome.
Method of Use[edit | edit source]
The NQ consosts of 16 items to be answered on a five point scale ranging from 'never' counted as zero to 'very often' counted as 4. The total score ranges from 0-64. Completion of the questionnaire only takes a few minutes.
A score of over 19 denotes the presence of respiratory distress and dysfunction. The higher the score the more distress is present. Values below 20 are considered within normal and functional domain.[1]

Evidence[edit | edit source]
Reliability[edit | edit source]
Validity[edit | edit source]
The sensitivity of the Nijmegen Questionnaire in relation to the clinical diagnosis was 91% and the specificity 95%[2]
Responsiveness[edit | edit source]
Advantages of the NQ is that it is short and responsive to treatment[1] Thus it can be used repeatedly over a course of treatment to measure progress.
