- Background: Guided internet-delivered CBT for anxiety disorders has received increasing empirical support, but little is known regarding the role of the therapist. Aims: This study addressed therapist factors in guided internet-delivered cognitive behavioural therapy for anxiety disorders. Method: Data from three controlled trials with a total N of 119 were analyzed with attention to differences between eight therapists. Results: No significant mean level differences between therapists appeared in the dataset. However, one significant intraclass correlation between participants was found, suggesting that the outcome on the Beck Anxiety Inventory might have been influenced by the impact of the individual therapists. Conclusion: The therapist can possibly have some influence on the outcome of guided internet-delivered CBT for anxiety disorders, but studies with more statistical power are needed to establish whether therapist effects are present in this modality of psychological treatment. The present study was underpowered to detect minor therapist effects.

- ObjectiveThe role of genetics for predicting the response to cognitive behavior therapy (CBT) for social anxiety disorder (SAD) has only been studied in one previous investigation. The serotonin transporter (5-HTTLPR), the catechol-o-methyltransferase (COMT) val158met, and the tryptophan hydroxylase-2 (TPH2) G-703Tpolymorphisms are implicated in the regulation of amygdala reactivity and fear extinction and therefore might be of relevance for CBT outcome. The aim of the present study was to investigate if these three gene variants predicted response to CBT in a large sample of SAD patients.MethodParticipants were recruited from two separate randomized controlled CBT trials (trial 1: n = 112, trial 2: n = 202). Genotyping were performed on DNA extracted from blood or saliva samples. Effects were analyzed at follow-up (6 or 12 months after treatment) for both groups and for each group separately at post-treatment. The main outcome measure was the Liebowitz Social Anxiety Scale Self-Report.ResultsAt long-term follow-up, there was no effect of any genotype, or gene × gene interactions, on treatment response. In the subsamples, there was time by genotype interaction effects indicating an influence of the TPH2 G-703T-polymorphism on CBT short-term response, however the direction of the effect was not consistent across trials.ConclusionsNone of the three gene variants, 5-HTTLPR, COMTval158met and TPH2 G-703T, was associated with long-term response to CBT for SAD.

- BackgroundInternet-delivered cognitive behavior therapy (ICBT) for major depression has been tested in several trials, but only with follow-ups up to 1.5 years.AimThe aim of this study was to evaluate the outcome of ICBT 3.5 years after treatment completion.MethodsA total of 88 people with major depression were randomized to either guided self-help or e-mail therapy in the original trial. One-third was initially on a waiting-list. Treatment was provided for eight weeks and in this report long-term follow-up data were collected. Also included were data from post-treatment and six-month follow-up. A total of 58% (51/88) completed the 3.5-year follow-up. Analyses were performed using a random effects repeated measures piecewise growth model to estimate trajectory shape over time and account for missing data.ResultsResults showed continued lowered scores on the Beck Depression Inventory (BDI). No differences were found between the treatment conditions. A large proportion of participants (55%) had sought and received additional treatments in the follow-up period. A majority (56.9%) of participants had a BDI score lower than 10 at the 3.5-year follow-up.ConclusionsPeople with mild to moderate major depression may benefit from ICBT 3.5-years after treatment completion.

Tidskriftsartikel (refereegranskat)abstract
- Internet-delivered cognitive behaviour therapy commonly consists of disorder-specific modules that are based on face-to-face manuals. A recent development in the field is to tailor the treatment according to patient profile, which has the potential to cover comorbid conditions in association with anxiety and mood disorders. However, it could be that the patients themselves are able to decide what modules to use. The authors tested this in an open pilot trial with 27 patients with mixed anxiety disorders. Modules were introduced with a brief description, and patients could choose which modules to use. The exception was the two first modules and the last, which involved psychoeducation and relapse prevention. The treatment period lasted for 10 weeks. Results showed large within-group effect sizes, with an average Cohen’s d of 0.88. In a structured clinical interview, a majority (54%) had significantly improved 10 weeks after commencing treatment. Only one person dropped out. On the basis of results of this preliminary study, the authors suggest that the role of choice and tailoring should be further explored in controlled trials and that patient choice could be incorporated into Internet-delivered treatment packages.

Tidskriftsartikel (refereegranskat)abstract
- Internet-delivered cognitive behavior therapy (ICBT) has been tested in many research trials, but to a lesser extent directly compared to face-to-face delivered cognitive behavior therapy (CBT). We conducted a systematic review and meta-analysis of trials in which guided ICBT was directly compared to face-to-face CBT. Studies on psychiatric and somatic conditions were included. Systematic searches resulted in 13 studies (total N=1053) that met all criteria and were included in the review. There were three studies on social anxiety disorder, three on panic disorder, two on depressive symptoms, two on body dissatisfaction, one on tinnitus, one on male sexual dysfunction, and one on spider phobia. Face-to-face CBT was either in the individual format (n=6) or in the group format (n=7). We also assessed quality and risk of bias. Results showed a pooled effect size (Hedges' g) at post-treatment of −0.01 (95% CI: −0.13 to 0.12), indicating that guided ICBT and face-to-face treatment produce equivalent overall effects. Study quality did not affect outcomes. While the overall results indicate equivalence, there are still few studies for each psychiatric and somatic condition and many conditions for which guided ICBT has not been compared to face-to-face treatment. Thus, more research is needed to establish equivalence of the two treatment formats.

- The Internet, including modern information technology, has had a dramatic impact on many areas of life, including health care and psychological treatment. In particular, cognitive–behavioral therapy (CBT) has been found to be a form of psychological treatment that has been possible to transfer to other modes of delivery than regular face-to-face and group formats. The Internet is not only useful for providing CBT, but has a significant role in providing information about CBT and conditions that are treated using CBT. In addition, modern information technology also has a major role in assessment procedures, such as online administration of self-report mea- sures. In this article, we focus mainly on Internet-supported treatments, although another emerging format is to use video conferencing systems and conduct real- time face-to-face CBT, CBT training, or supervision.

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.

- BACKGROUND:Major depression can be treated by means of cognitive-behavioural therapy, but as skilled therapists are in short supply there is a need for self-help approaches. Many individuals with depression use the internet for discussion of symptoms and to share their experience.AIMS:To investigate the effects of an internet-administered self-help programme including participation in a monitored, web-based discussion group, compared with participation in web-based discussion group only.METHOD:A randomised controlled trial was conducted to compare the effects of internet-based cognitive-behavioural therapy with minimal therapist contact (plus participation in a discussion group) with the effects of participation in a discussion group only.RESULTS:Internet-based therapy with minimal therapist contact, combined with activity in a discussion group, resulted in greater reductions of depressive symptoms compared with activity in a discussion group only (waiting-list control group). At 6 months' follow-up, improvement was maintained to a large extent.CONCLUSIONS:Internet-delivered cognitive cognitive-behavioural therapy should be pursued further as a complement or treatment alternative for mild-to-moderate depression.
