Analysis

The Nijmegen Hyperventilation Scale (NHS) is a psychometric tool developed to assess symptoms related to hyperventilation. The questionnaire is designed to evaluate the severity of hyperventilation symptoms and assist in diagnosing individuals suffering from this condition.

Objective

The main goal of the NHS is to provide a reliable method for assessing hyperventilation symptoms and to facilitate their diagnosis and management. The NHS helps to understand the extent to which hyperventilation affects individuals’ daily lives and provides useful information for developing appropriate intervention strategies.

Scoring

The NHS includes 16 statements related to hyperventilation symptoms, and participants are asked to rate the intensity of their symptoms on a Likert scale, usually from 0 (never) to 4 (always). The total score is calculated by summing the ratings for all statements, with higher scores indicating more severe hyperventilation symptoms.
