  • +8 more secondary outcomes

Study Arms (2)

Internet-CBT

EXPERIMENTAL

The internet-CBT will comprise 8 weekly modules with therapist-support, encouraging exposure for fear of asthma symptoms while ensuring a stable asthma medication through a written medical plan on medical adherence Participants work independently from home with the treatment and receive weekly support from their psychologist through written messages online.

Behavioral: Exposure-based Internet-CBT

Treatment as usual

OTHER

Patients randomized to treatment as usual will receive the same medical information that participants in the Internet-CBT get, with physiological information about asthma and the importance of medical adherence to achieve well controlled asthma, but without the exposure-based treatment and no therapist support. All participants in both conditions can use any other available treatment, but psychological, from pre-assessments to 2 months after treatment completion. Participants in this arm will be crossed over to Internet-CBT after the primary endpoint at to 2 months follow up.

Other: Treatment as usual

Interventions

Internet-CBT for anxiety-related asthma 8 weekly modules of CBT delivered over the internet and targeting enhanced function and decreased symptoms of anxiety. Participants work independently from home with the treatment and receive support from experienced Internet-CBT Psychologists through written messages in the secure platform. All participants in both conditions can use any other available treatment (TAU), but psychological, from pre-assessments to 2 months after treatment completion.
