Primary study designInterventional
Study designRandomized controlled multicenter trial
Secondary study designRandomised controlled trial
Study type Participant information sheet
Scientific titleThe social phobia psychotherapy research network
Study acronymSOPHO-NET
Study objectivesDifferential efficacy of short-term psychodynamic psychotherapy (STPP) and cognitive-behavioral therapy (CBT) in social phobia therapy - named hypothesis A1

The first add-on study (named C1) of this multicentre trial will be studying genetic polymorphisms in patients with social phobia who are treated with STPP and CBT.

The second add-on study (named C2) of this multicentre trial will be studying the neural functional and structural changes in patients with social phobia who are treated with STPP and CBT.

The third add-on study (named C3) of this multicentre trial will be studying the attachment characteristics as differential predictors of treatment outcome in 128 patients with social phobia who are treated with STPP and CBT.
Ethics approval(s)Ethics Committee of the Medical Faculty of the University of Goettingen, 06/12/2006
Health condition(s) or problem(s) studiedSocial phobia (social anxiety disorder)
InterventionManualized short-term psychodynamic psychotherapy (STPP) versus manualized cognitive-behavioral therapy (CBT)
Intervention typeOther
Primary outcome measure(s)For A1, primary outcome is no diagnosis of SP according to the SCID-I DSM-IV and the Liebowitz Social Anxiety Scale

For C1, the primary outcome will be, that the psychotherapy outcome is associated with genetic variation in the serotonin transporter (SERT) gene (directed: L12 higher pre-post difference in the Liebowitz Social Anxiety Scale [LSAS])

For C2, primary outcomes will include normalisation of neural structural and functional abnormalities after successful treatment

For C3, primary outcomes will be whether patients reveal a secure organized attachment; representation will reach a better outcome than those with insecure features and\or disorganized states of mind
Key secondary outcome measure(s)For A1, secondary outcomes will include:
1. Social anxiety (Social Phobia and Anxiety Inventory [SPAI])
2. Depression (Beck Depression Inventory [BDI])
3. Interpersonal problems (IIP)
4. Self-image
5. Quality of life or social functioning (short-form-12 questionnaire [SF-12])
6. Costs and utilities of the treatments

For C1, the secondary outcome will be, that the severity of social phobia is linked with genetic variation in SERT gene (directed: S10 higher LSAS at baseline)

For C2 secondary outcome will include specificity of neural structural and functional abnormalities in social phobia

For C3, secondary outcome will include whether a self-reported attachment will significantly change after successful therapy indicating increased security. This will be tested by using the Experiences in Close Relationships-Revised (ECR-R) instrument within the entire sample (n = 512)
