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
Mostly used for people with hyperventilation syndrome.
Method of Use
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.

162 Greek asthma out-patients (86 with mild and 76 moderate asthma) participated in the study. Hyperventilation was assessed using NQ and clinical measures such as breath holding time (BHT), respiratory rate (RR) and end-tidal CO2 (ETCO2). Construct validity was tested through factor analysis and cross-sectional validity through correlations of the NQ score with BHT, ETCO2 and RR (Pearson’s r correlation coefficient).
The sensitivity of the Nijmegen Questionnaire in relation to the clinical diagnosis was 91% and the specificity 95%
Advantages of the NQ is that it is short and responsive to treatment Thus it can be used repeatedly over a course of treatment to measure progress.
The NQ was valid and reliable in the present sample with asthma.
