Brief Summary

Forty-eight people diagnosed with social phobia in an experimental study that randomized into two treatment groups: 1) Internet-based Cognitive Behavioural Therapy (iCBT) (n = 24) or 2) computerized attention training (n = 24). After nine weeks we change the condition of the two groups of research participants, which should therefore be given both treatments. Pre-and post measurement of functional magnetic resonance imaging (fMRI) will take place in the first round of treatment. Genotyping based on saliva samples takes place before the start of treatment, at the first fMRI measurement, for those who voluntarily leave the sample. Study hypothesis How is the brain activity of emotional processing and anxiety affected after completing an Internet-based CBT compared with computerized attention training? Does the treatment response of an Internet based treatment affects by variations in serotonin-transporter-linked promoter region (5-HTTLPR) and tryptophan hydroxylase-3 (TPH3) genes? How is the genetic variations related to symptoms in social phobia (pre treatment)?

Cognitive behavior therapy via the internet

ACTIVE COMPARATOR

Cognitive behavior therapy via the internet with therapist support.

Behavioral: Internet-based cognitive behavioural therapy (iCBT)

Attentional retraining

ACTIVE COMPARATOR

Attentional retraining as described by Nader Amir.

Behavioral: Internet-based computerized attention training

Interventions

The Internet-based cognitive behavioural therapy (iCBT) consists of our structured self-help program lasting a total of nine active treatment weeks. This treatment program has been well evaluated and involved in several research projects.

Cognitive behavior therapy via the internet

The Internet-based computerized attention training program lasting a total of four active treatment weeks. The treatment is consist of two training sessions per week, about 10 minutes long.
