How the Scales are Structured

example score

35/64

Total Score (TS)

This scale sums symptom frequency to indicate the likelihood of hyperventilation-related ventilation dysregulation.

Low likelihood

High likelihood

0 – 22: Low likelihood | 23 – 64: High likelihood

A total score of 35 falls in the High likelihood range, indicating a higher probability of hyperventilation syndrome compared with scores at or below 22.

WHAT THE TEST MEASURES

About This Assessment

Nijmegen Questionnaire Test - Symptoms and Signs

somatics

vegetative dysfunction

This brief self-report measure screens for symptoms commonly associated with dysregulated breathing patterns. The Nijmegen Questionnaire is used to quantify the frequency of physical sensations that may co-occur with hyperventilation-related complaints.

It consists of 16 items and typically takes about 3 minutes to complete. Respondents rate how often they experience a range of somatic symptoms (e.g., dizziness, shortness of breath, tingling), supporting initial triage and helping determine whether further clinical assessment of breathing-related symptoms may be warranted.

The Nijmegen Questionnaire was developed by Jan Duivenvoorden and David H. Van Dixhoorn and is intended for screening and monitoring purposes rather than stand-alone diagnosis.
