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.

CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

What does this questionnaire measure?

It screens for symptoms commonly associated with overbreathing and ventilation imbalance. It does not provide a diagnosis.

How long does it take and how many items are included?

Completion typically takes about 3 minutes. It includes 16 items.

What types of symptoms are covered?

Items cover physical sensations linked to breathing dysregulation, such as dizziness, shortness of breath, and tingling or numbness. Symptoms are rated by frequency.

How should responses be selected?

Select the option that best reflects how often each symptom has occurred recently. Use the first response that seems accurate and avoid overthinking.

How should results be interpreted and used?

Higher scores indicate a greater likelihood of clinically relevant hyperventilation-related symptoms. Results should be considered alongside clinical evaluation and other findings.

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.
