Randomized Controlled Trial
Guided internet-delivered cognitive behavior therapy for generalized anxiety disorder: a randomized controlled trial.
Generalized anxiety disorder (GAD) has been effectively treated with cognitive behavioural therapy (CBT) in face-to face settings. Internet-delivered CBT could be a way to increase the accessibility and affordability of CBT for people suffering from GAD. The aim of this study was to evaluate the efficacy of guided Internet-delivered CBT for GAD in a controlled trial with a wait-list control group. ⋯ Large effect sizes (Cohen's d > 0.8) were found both within the treatment group and between the groups in favor of the treatment on all outcome measures except on a measure of quality of life. Results at 1- and 3-year follow-up indicated that treatment results improved or were maintained. The authors conclude that Internet-delivered CBT with therapist support can reduce symptoms and problems related to GAD.

Randomized Controlled Trial
Internet-based treatment of depression: a randomized controlled trial comparing guided with unguided self-help.
Internet-delivered self-help for depression with therapist guidance has shown efficacy in several trials. Results from meta-analyses suggest that guidance is important and that self-help programs without support are less effective. However, there are no direct experimental comparisons between guided and unguided internet-based treatments for depression. ⋯ In both groups, treatment gains were maintained at 6-month follow-up. The findings provide evidence that internet-delivered treatments for depression can be effective whether support is added or not. However, all participants were interviewed in a structured diagnostic telephone interview before inclusion, which prohibits conclusions regarding unguided treatments that are without any human contact.
