The Rainbow Study - the Effect of Feedback on Asthmatic Symptom Perception

Asthma is a common childhood disease that is characterized by chronic airway inflammation and episodic expiratory airflow obstruction. Asthma symptoms can impair participation in play and sports and have a negative impact on quality of life. It can be challenging for children to adequately feel and report their symptoms. Some children experience more symptoms than expected based on lung function during these symptoms, whereas others experience less symptoms than expected. This is also called 'symptom perception'.

A tool was developed to visualize symptoms, lung function and accessory symptom perception: The Rainbow tool. The aim of this study was to identify asthmatic children with a poor perception and investigate if their symptom perception could be improved by regular lung function measurements and personal feedback based on the Rainbow Tool.

Hypothesis: Measuring lung function en symptoms and provide personal feedback on perception based on the Rainbow tool has a positive effect on perception of asthma-related symptoms in asthmatic children.
