Validating the Breathing Vigilance Questionnaire for use in dysfunctional breathing

Dysfunctional breathing is common among people with and without primary respiratory pathology. While anxiety can contribute to dysfunctional breathing, the underpinning mechanism is unclear. One explanation is that anxiety induces conscious, vigilant monitoring of breathing, disrupting "automatic" breathing mechanics. We validated a new tool that quantifies such breathing-related "vigilance": the Breathing Vigilance Questionnaire (Breathe-VQ).
