Brief Summary

This is a study to develop a protocol on Cognitive behavior therapy (CBT) for asthma-related anxiety that in a consecutive study can be translated to internet-delivered CBT.

Detailed Description

Asthma is one of the most common chronic diseases around the world, with a high prevalence of anxiety disorders. Cognitive behaviour therapy (CBT) has been shown to increase psychological well-being for anxiety-related asthma.

Ten participants will be included in a single-subject multiple baseline design. They will all receive 10-12 sessions of CBT.
