Scientific basis

Internet-based self-help treatments have proved to be effective in a number of different conditions.

The patients are provided with access to treatment manuals over the Internet while receiving psychological support via e-mail or phone.

Studies have shown that the effectiveness of Internet-based CBT treatments with minimal support are comparable with the effectiveness of both real life individual treatments and treatments in groups.

Internetpsykiatri offers Internet treatment (ICBT) for depression, IBS, insomnia, health anxiety, panic disorder and social phobia (social anxiety syndrome). OCD-programmet offers ICBT for body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD). Our treatments are founded on a scientific research.

Our treatment results are evaluated continuously and reported to the quality register SibeR ( The proportion of patients, who have received each treatment, that has improved significantly after treatment is as follows for the past year (this is based on a reduction in the severity of symptoms by at least 30% (health anxiety, IBS and social phobia) and 40% (depression, insomnia and panic disorder); updated February 2022):

  • Depression 44%
  • Health anxiety 45%
  • Insomnia (sleep problems) 48%
  • Irritable bowel syndrome (IBS) 41%
  • Panic disorder 59%
  • Social phobia 45%
