- The aim of this study was to compare guided Internet-delivered to group-delivered cognitive behavioral therapy (CBT) for insomnia. We conducted an 8-week randomized controlled non-inferiority trial with 6-months follow-up. Participants were forty-eight adults with insomnia, recruited via media. Interventions were guided Internet-delivered CBT (ICBT) and group-delivered CBT (GCBT) for insomnia. Primary outcome measure was the Insomnia Severity Index (ISI), secondary outcome measures were sleep diary data, depressive symptoms, response- and remission rates. Both treatment groups showed significant improvements and large effect sizes for ISI (Within Cohen's d: ICBT post = 1.8, 6-months follow-up = 2.1; GCBT post = 2.1, 6-months follow-up = 2.2). Confidence interval of the difference between groups posttreatment and at FU6 indicated non-inferiority of ICBT compared to GCBT. At post-treatment, two thirds of patients in both groups were considered responders (ISI-reduction > 7p). Using diagnostic criteria, 63% (ICBT) and 75% (GCBT) were in remission. Sleep diary data showed moderate to large effect sizes. We conclude that both guided Internet-CBT and group-CBT in this study were efficacious with regard to insomnia severity, sleep parameters and depressive symptoms. The results are in line with previous research, and strengthen the evidence for guided Internet-CBT for insomnia. Trial registration: The study protocol was approved by, and registered with, the regional ethics review board in Linkoping, Sweden, registration number 2010/385-31. (C) 2015 The Authors.

- A randomized trial was conducted comparing 10 individual weekly sessions of cognitive behaviour therapy for panic disorder (PD) with or without agoraphobia with a 10-module self-help program on the Internet. After confirming the PD diagnosis with an in-person structured clinical interview (SCID) 49 participants were randomized. Overall, the results suggest that Internet-administered self-help plus minimal therapist contact via e-mail can be equally effective as traditional individual cognitive behaviour therapy. Composite within-group effect sizes were high in both groups, while the between-group effect size was small (Cohen's d=16). One-year follow-up confirmed the results, with a within-group effect size of Cohen's d=0.80 for the Internet group and d=0.93 for the live group. The results from this study generally provide evidence to support the continued use and development of Internet-distributed self-help programs.

- Social anxiety disorder (SAD) is common, debilitating and associated with high societal costs. The disorder can be effectively treated with Internet-based cognitive behavior therapy (ICBT), but no previous study has investigated the long-term clinical or health economic effects of ICBT for SAD in comparison to an evidence-based control treatment. The aim of the study was to investigate the clinical effectiveness and cost-effectiveness of ICBT compared to cognitive behavioral group therapy (CBGT) four years post-treatment. We conducted a 4-year follow-up study of participants who had received ICBT or CBGT for SAD within the context of a randomized controlled non-inferiority trial. The cost-effectiveness analyses were conducted taking a societal perspective. Participants in both treatment groups made large improvements from baseline to 4-year follow-up on the primary outcome measure (d = 1.34-1.48) and the 95% CI of the mean difference on the primary outcome was well within the non-inferiority margin. ICBT and CBGT were similarly cost-effective and both groups reduced their indirect costs. We conclude that ICBT for SAD yields large sustainable effects and is at least as long-term effective as CBGT. Intervention costs of both treatments are offset by net societal cost reductions in a short time. (C) 2014 Elsevier Ltd. All rights reserved.

- Aim: To evaluate if internet-delivered Cognitive Behavioral Therapy for insomnia (ICBT-i) with brief therapist support outperforms an active control treatment. Method: Adults diagnosed with insomnia were recruited via media (n = 148) and randomized to either eight weeks of ICBT-i or an active internet-based control treatment. Primary outcome was the insomnia severity index (ISI) assessed before and after treatment, with follow-ups after 6 and 12 months. Secondary outcomes were use of sleep medication, sleep parameters (sleep diary), perceived stress, and a screening of negative treatment effects. Hierarchical Linear Mixed Models were used for intent-to-treat analyses and handling of missing data. Results: ICBT-i was significantly more effective than the control treatment in reducing ISI (Cohen's d = 0.85), sleep medication, sleep efficiency, sleep latency, and sleep quality at post-treatment. The positive effects were sustained. However, after 12 months the difference was no longer significant due to a continuous decrease in ISI among controls, possibly due to their significantly higher utilization of insomnia relevant care after treatment Forty-six negative effects were reported but did not differ between interventions. Conclusions: Supported ICBT-i is more effective than an active control treatment in reducing insomnia severity and treatment gains remain stable one year after treatment (C) 2015 The Authors.
