In our study, we aimed to evaluate the validity and reliability of the Turkish version of the Breathlessness Beliefs Questionnaire-BBQ in our study.

Pulmonary diseases are a common cause of mortality and morbidity throughout the world. In pulmonary diseases such as asthma and COPD, the main symptom is dyspnea and it causes activity limitation. Dyspnea is defined as the difficulty that a person experiences during breathing. As a result of painful situations or injuries, avoidance of physical activity or movement due to the fear of repetition of the problem are defined as kinesophobia. Pulmonary patients are compensated by reducing the rate of activity, while avoiding dyspnea.This reduces the severity of the symptom that precedes the symptom that may occur. As a result, dyspnea causes kinesyphobia. Decrease in the level of activity; social isolation, fear of dyspnea, depression and anxiety result in a stubborn cycle, quality of life is reduced. The Breathlessness Beliefs Questionnaire (BBQ) was developed based on the Tampa Kinesiophobia Scale to assess dyspnea and dyspnoea-related kinesophobia and anxiety in respiratory diseases.
