Forskningsöversikt (refereegranskat)abstract
- Therapist-guided internet-based cognitive behavior therapy (ICBT) has been tested in numerous controlled trials conducted in research settings. It is now established that this novel treatment format works for a range of clinical conditions. It is less well known if the promising results from efficacy studies can be transferred to routine clinical practice. In this paper we review the evidence from effectiveness studies and highlight challenges when implementing ICBT. Following literature searches we identified 4 controlled trials and 8 open studies, involving a total of 3,888 patients. There is now an increasing number of effectiveness studies on ICBT with studies on panic disorder, social anxiety disorder, generalized anxiety disorder, post-traumatic stress disorder, depression, tinnitus, and irritable bowel syndrome. All indicate that it is possible to transfer ICBT to clinical practice with sustained effects and moderate to large effect sizes. However, it is not clear which model to use for service delivery, and more work remains to be done on dissemination of ICBT. Moreover, the knowledge about outcome predictors from controlled efficacy trials is probably less relevant, and studies with large clinically representative samples are needed to investigate for which patients ICBT is suitable. In this work existing data could be combined and reanalyzed to study predictors of outcome.

- The aim of this study was to investigate if future thinking would change following two forms of Internet-delivered cognitive behavior therapy (ICBT) for major depression. A second aim was to study the association between pre-post changes in future thinking and pre-post changes in depressive symptoms. Effects of psychological treatments are most often tested with self-report inventories and seldom with tests of cognitive function. We included data from 47 persons diagnosed with major depression who received either e-mail therapy or guided self-help during 8 weeks. Participants completed a future thinking task (FTT), in which they were asked to generate positive and negative events that they thought were going to happen in the future and rated the events in terms of emotion and likelihood. The FTT was completed before and after treatment. Data on depressive symptoms were also collected. FTT index scores for negative events were reduced after treatment. There was no increase for the positive events. Change scores for the FTT negative events and depression symptoms were significantly correlated. We conclude that ICBT may lead to decreased negative future thinking and that changes in depression symptoms correlate to some extent with reductions in negative future thinking.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Guided Internet-delivered treatments were developed in the late 1990s and have since been tested in numerous controlled trials. While promising, there are yet few direct comparisons between Internet treatments and traditional face-to-face treatments. The aim of the present study is to present an overview of the evidence in the field of anxiety disorders. Method: Studies were located, including unpublished trials from our research group in Sweden. Results: Results of direct comparative trials on panic disorder (n=3) and social anxiety disorder (n=3) show equivalent outcomes. One study on specific phobia did not show equivalent outcomes with an advantage for face-to-face treatment. However, a systematic review by Cuijpers et al. (2010) found equivalent outcomes across several self-help formats, suggesting that guided self-help overall can be as affective as face-to-face treatments. Conclusion: Overall, there are still few large-scale trials and statistical power is often limited. A preliminary conclusion is that guided Internet treatment can be as effective as face-to-face treatments, but there is a need to investigate moderators and mediators of the outcome.

Tidskriftsartikel (refereegranskat)abstract
- In this study, the authors compared guided Internet-delivered self-help with one-session exposure treatment (OST) in a sample of snake phobic patients. A total of 30 patients were included following a screening on the Internet and a structured clinical interview. The Internet treatment consisted of four weekly text modules which were presented on a web page, a video in which exposure was modelled, and support provided via Internet. The OST was delivered in a three-hour session following a brief orientation session. The main outcome was the behavioural approach test (BAT), and as secondary measures questionnaires measuring anxiety symptoms and depression were used. Results showed that the groups did not differ at post-treatment or follow-up, with the exception of a significant interaction for the BAT in favour of the OST. At post-treatment, 61.5% of the Internet group and 84.6% of the OST group achieved a clinically significant improvement on the BAT. At follow-up, the corresponding figures were 90% for the Internet group and 100% for the OST group (completer sample). Within-group effect sizes for the Snake Phobia Questionnaire were large (d = 1.63 and d = 2.31 for the Internet and OST groups, respectively, at post-treatment). It is concluded that guided Internet-delivered exposure treatment is a potential treatment option in the treatment of snake phobia, but that OST probably is better.

Tidskriftsartikel (refereegranskat)abstract
- Background: Guided Internet-based cognitive behavior therapy (ICBT) has been tested in many trials and found to be effective in the treatment of anxiety and mood disorders. Generalized anxiety disorder (GAD) has also been treated with ICBT, but there are no controlled trials on guided Internet-based psychodynamic treatment (IPDT). Since there is preliminary support for psychodynamic treatment for GAD, we decided to test if a psychodynamically informed self-help treatment could be delivered via the Internet. The aim of the study was to investigate the efficacy of IPDT for GAD and to compare against ICBT and a waiting list control group.Method: A randomized controlled superiority trial with individuals diagnosed with GAD comparing guided ICBT (n = 27) and IPDT (n = 27) against a no treatment waiting list control group (n = 27). The primary outcome measure was the Penn State Worry Questionnaire.Results: While there were no significant between-group differences immediately after treatment on the main outcome measure, both IPDT and ICBT resulted in improvements with moderate to large within-group effect sizes at 3 and 18 months follow-up on the primary measure in the completer analyses. The differences against the control group, although smaller, were still significant for both PDT and CBT when conforming to the criteria of clinically significant improvement. The active treatments did not differ significantly. There was a significant group by time interaction regarding GAD symptoms, but not immediately after treatment.Conclusions: IPDT and ICBT both led to modest symptom reduction in GAD, and more research is needed.Copyright (C) 2012 S.

- Purpose of review The aim of this paper is to provide an updated review of recent controlled trials of Internet interventions for health conditions and how the Internet is used to promote health. Recent findings We identified 18 published trials including studies on diabetes, cancer, pain conditions, obesity, irritable bowel syndrome, stress management, hypertension, metabolic syndrome, cerebral palsy, infertility, HIV infection, and fruit/vegetable consumption. Of the 18 trials, one-third targeted children and adolescents. Two cancer studies investigated the role of peer support in an online environment that failed to result in any major improvements. Overall, several trials did not result in any substantial significant improvements, but there are exceptions, such as treatment of irritable bowel syndrome, headache, and chronic pain. Although a few of the reviewed studies had sufficient sample sizes, the majority were small and underpowered. In particular, this was the case for the studies on children and adolescents. Summary This review suggests that Internet interventions hold some promise as a complement to other treatments such as cognitive behavior therapy. The benefits from participating in online peer support groups are not clear. Although studies on children and adolescents have emerged, there is a lack of studies on older adults with health problems.

- Lars-Göran Öst is one of the most eminent clinical researchers in the field of cognitive behaviour therapy (CBT) and a founder of CBT in Sweden. He has recently retired from his position as professor in clinical psychology at Stockholm University, Sweden. In this paper, we sketch a brief description of the body of work by Öst. Examples of his innovative and pioneering new treatment methods include the one-session treatment for specific phobias, as well as applied relaxation for a range of anxiety disorders and health conditions. While Öst remains active in the field, he has contributed significantly to the development and dissemination of CBT in Sweden as well as in the world.
