Study summary

Stress disorders in form of adjustment disorder and burnout syndrom are highly prevalent and cause substantial suffering. Prior evidence suggest that these disorders may be effectively treated with cognitive behavior therapy (CBT), but access to psychological treatment is limited. One possible solution is to provide therapy via the Internet, which has been shown to be effective for anxiety disorders and depression. In the present study, we will investigate the efficacy of Internet-based CBT (ICBT) for adjustment disorders and burnout syndrom in a randomized controlled trial (N=100). Participants will be randomized to active treatment (n=50) or a control condition on waiting list.

Stress disorders in form of adjustment disorder and burnout syndrom are highly prevalent and cause substantial suffering. Prior evidence suggest that these disorders may be effectively treated with cognitive behavior therapy (CBT), but access to psychological treatment is limited. One possible solution is to provide therapy via the Internet, which has been shown to be effective for anxiety disorders and depression. Internet-based CBT can be described as online bibliotherapy with therapist support via a secure messaging system. In this study psychologists will deliver the treatment. We will investigate the efficacy of Internet-based CBT (ICBT) for adjustment disorder and burnout syndrom in a randomized controlled trial (N=100). Participants will be randomized to active treatment (n=50) or a control condition on waiting list. We expect that participants who receive ICBT will make superior improvements compared to the control condition on measures of stress, burnout, depressive symptoms, general anxiety and general functioning.

Study arms

  • Experimental
    Active treatment, Internet-based CBT

    Internet-based treatment with therapist support using an asynchronous messaging system. The treatment is comprised of 12 modules (similar to chapters) and the treatment is 12 weeks long. The treatment is based on cognitive behavior therapy. Participants will be stratified based on diagnosis, i.e. adjustment disorder and burnout.

    Behavioral: Internet-based CBT

  • No intervention
    Waiting list control

    The control condition is a waiting list. Participants in this arm receive no active treatment. After 12 weeks on waiting list, participants are crossed over to treatment.

Interventions

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 16, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
