AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children aged 7 to 15 with asthma diagnosed by a pediatrician, whose health care professional thinks they may not feel their symptoms well. It tests whether regular lung tests and personal feedback help.
- Age
- 7 to 15 years
- Sex
- Boys and girls
- Disease stage
- Asthma diagnosed by a pediatrician. After a selection phase, the trial is looking for children whose symptom perception is poor on the Perception Rainbow.
- Earlier treatment
- No medication change in the past 2 weeks. No flare-up that needed oral prednisone in the past 6 weeks.
- Biomarker or test result
- Enough lung function measurements and VAS scores in the selection phase: at least 4 after exercise or with symptoms, and at least 2 standard ones. Poor perception shown by measurements in the red, orange or yellow zone of the Perception Rainbow.
Main reasons for not taking part
- Severe other illness, for example psychomotor retardation or severe heart and lung conditions
- Cannot fill in a VAS score, for example due to blindness
- Cannot do the lung function test (spirometry) correctly
- Flare-up at the time of joining
- No computer, tablet or smartphone with internet at home

- Original description
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'.Read full original descriptionShow less
The Rainbow Study - a Randomized Controlled Trial to Evaluate the Effect of Personalized Feedback on Symptom Perception in Asthmatic Children
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.
Inclusion: Selection phase:; Pediatrician diagnosed asthma; Health care professional thinks perception might be poor; Age 7 until 15 years old; Adequate understanding of Dutch language; Intervention phase:; Adequate number of lung function measurements + VAS scores during selection phase, defined as:; At least 4 measurements after exercise or when experiencing symptoms and; At least 2 standard measurements; Poor perception during selection phase, defined as:; At least 1 measurement in red zone on Perception Rainbow and/or; At least 2 measurements in orange zone on Perception Rainbow and/or; Average of all measurements after exercise or when experiencing symptoms in yellow zone (or orange/red)and/or; Average of all measurements in yellow zone (or orange/red).
Exclusion: Medication change in past 2 weeks; Severe comorbidity (for example psychomotor retardation or severe cardiopulmonary conditions); Not able to fill in VAS score (for example due to blindness); Not able to perform technically correct spirometry manoeuvres; Exacerbation which required oral prednisone in the past 6 weeks; Exacerbation at the moment of inclusion; No device (computer, tablet or smartphone) with internet connection available at home.
