About this trial

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.

Eligibility criteria

Adequate understanding of Dutch language

Disqualifiers

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

Trial design

Design model

Parallel

Treatments tested in this trial

  • Rainbow tool

    Behavioral

    The Rainbow tool visualizes perception based on lung function measurements and VAS scores.

  • Feedback

    Behavioral

    Feedback sessions with health care professional based on the Rainbow tool.

Treatment groups

39 Participants

Trial outcomes

Primary outcomes

1

Perception score

The difference in the average perception score (0-100) during the two-week run-in and last week of the intervention between the intervention group (with feedback) and the control group

Time frame
Two week run-in versus last week of intervention

Secondary outcomes

1

Perception score intervention groups

Difference between average perception score of intervention group (with feedback) and intervention (without feedback) group per week

Time frame
Measured per week during the study period, which is 8 weeks
2

Perception score over time

Perception scores (0-100) and average perception score per week. Including over- or underperception

Time frame
Measured per week during the study period, which is 8 weeks
3

Perception score zones

Number of perception scores in green/yellow/red zone (absolute and relative) per week

Time frame
Measured per week during the study period, which is 8 weeks
4

Additional symptoms

Type of additional symptom when measurement (lung function + VAS) is performed: no additional symptoms, cough, wheezing, chest pain, feeling dizzy, nasal symptoms

Time frame
Measured per week during the study period, which is 8 weeks
