The study seeks to investigate the efficacy of two internet-based self-help programmes administered with support from a therapist. The two active conditions consist of an internet cognitive behavioral therapy (ICBT) programme and a intervention of internet-based interpersonal psychotherapy (IIPT), both of which have been developed for the present study. The active conditions will be compared to a wait-list control group.
Participants will be recruited in Sweden with a nationwide recruitment.

| Change on Patient Health Questionnaire (PHQ-9) | Measure of depressive symptoms. Possible range for the total sum: 0 to 27 (created by summing up the score from each item). Clinical cut-offs for mild, moderate, moderately severe and severe major depressive disorder are considered to be 5, 10, 15, and 20 points. | 10 weeks after start of intervention, at 4 month follow-up, at 12 month follow-up |
| Change on Social Interaction Anxiety Scale (SIAS) | Measure of social interaction anxiety, closely correlated with social anxiety disorder. The score on each of the 20 items are summed up. Possible range for the total sum between 0 and 80. Higher scores indicate a higher degree of social interaction anxiety. | 10 weeks after start of intervention, at 4 month follow-up, at 12 month follow-up |
| Change on Generalised Anxiety Disorder 7-item scale (GAD-7) | Measure of symptoms of generalised anxiety disorder (GAD). Seven items, the score is interpreted by summing up the score from each individual item. Higher scores indicate more severe problems with worry and generalised anxiety. The total sum ranges from 0 to 21 with cut-offs of 5, 10, and 15 representing mild, moderate and severe generalised anxiety. | 10 weeks after start of intervention, at 4 month follow-up, at 12 month follow-up |
