- 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.

Cost-effectiveness of internet-based cognitive behavior therapy for irritable bowel syndrome: results from a randomized controlled trial
- 2011
-
In: BMC Public Health. - : BioMed Central. - 1471-2458. ; 11:215
-
Journal article (peer-reviewed)abstract
- Background: Irritable Bowel Syndrome (IBS) is highly prevalent and is associated with a substantial economic burden. Cognitive behavior therapy (CBT) has been shown to be effective in treating IBS. The aim of this study was to evaluate the cost-effectiveness of a new treatment alternative, internet-delivered CBT based on exposure and mindfulness exercises. Methods: Participants (N = 85) with IBS were recruited through self-referral and were assessed via a telephone interview and self-report measures on the internet. Participants were randomized to internet-delivered CBT or to a discussion forum. Economic data was assessed at pre-, post- and at 3-month and 1 year follow-up. Results: Significant cost reductions were found for the treatment group at $16,806 per successfully treated case. The cost reductions were mainly driven by reduced work loss in the treatment group. Results were sustained at 3-month and 1 year follow-up. Conclusions: Internet-delivered CBT appears to generate health gains in IBS treatment and is associated with cost-savings from a societal perspective.

Journal article (peer-reviewed)abstract
- Background: Cognitive behavior therapy (CBT) is widely regarded as an effective treatment for obsessive compulsive disorder (OCD), but access to CBT therapists is limited. Internet-based CBT (ICBT) with therapist support is a way to increase access to CBT but has not been developed or tested for OCD. The aim of this study was to evaluate ICBT for OCD. less thanbrgreater than less thanbrgreater thanMethod: An open trial where patients (N = 23) received a 15-week ICBT program with therapist support consisting of psychoeducation, cognitive restructuring and exposure with response prevention. The primary outcome was the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), which was assessed by a psychiatrist before and immediately after treatment. Secondary outcomes were self-rated measures of OCD symptoms, depressive symptoms, general functioning, anxiety and quality of life. All assessments were made at baseline and post-treatment. less thanbrgreater than less thanbrgreater thanResults: All participants completed the primary outcome measure at all assessment points. There were reductions in OCD symptoms with a large within-group effect size (Cohens d = 1.56). At post-treatment, 61% of participants had a clinically significant improvement and 43% no longer fulfilled the diagnostic criteria of OCD. The treatment also resulted in statistically significant improvements in self-rated OCD symptoms, general functioning and depression. less thanbrgreater than less thanbrgreater thanConclusions: ICBT with therapist support reduces OCD symptoms, depressive symptoms and improves general functioning. Randomized trials are needed to confirm the effectiveness of this new treatment format.

Can the patient decide which modules to endorse? : an open trial of tailored internet treatment of anxiety disorders
- 2011
-
In: Cognitive Behaviour Therapy. - : Routledge, Taylor and Francis Group. - 1650-6073 .- 1651-2316. ; 1:40, s. 57-64

Journal article (peer-reviewed)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.

Journal article (peer-reviewed)abstract
- 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.

Intraclass correlation associated with therapists : estimates and applications in planning psychotherapy research
- 2011

Journal article (peer-reviewed)abstract
- It is essential that outcome research permit clear conclusions to be drawn about the efficacy of interventions. The common practice of nesting therapists within conditions can pose important methodological challenges that affect interpretation, particularly if the study is not powered to account for the nested design. An obstacle to the optimal design of these studies is the lack of data about the intraclass correlation coefficient (ICC), which measures the statistical dependencies introduced by nesting. To begin the development of a public database of ICC estimates, the authors investigated ICCs for a variety outcomes reported in 20 psychotherapy outcome studies. The magnitude of the 495 ICC estimates varied widely across measures and studies. The authors provide recommendations regarding how to select and aggregate ICC estimates for power calculations and show how researchers can use ICC estimates to choose the number of patients and therapists that will optimize power. Attention to these recommendations will strengthen the validity of inferences drawn from psychotherapy studies that nest therapists within conditions.

Experiences of guided Internet-based cognitive-behavioural treatment for depression : A qualitative study
- 2011
-
In: BMC Psychiatry. - : BioMed Central. - 1471-244X. ; 11:107
-
Journal article (peer-reviewed)abstract
- Background: Internet-based self-help treatment with minimal therapist contact has been shown to have an effect in treating various conditions. The objective of this study was to explore participants’ views of Internet administrated guided self-help treatment for depression. Methods: In-depth interviews were conducted with 12 strategically selected participants and qualitative methods with components of both thematic analysis and grounded theory were used in the analyses. Results: Three distinct change processes relating to how participants worked with the treatment material emerged which were categorized as (a) Readers, (b) Strivers, and (c) Doers. These processes dealt with attitudes towards treatment, views on motivational aspects of the treatment, and perceptions of consequences of the treatment. Conclusions: We conclude that the findings correspond with existing theoretical models of face-to-face psychotherapy within qualitative process research. Persons who take responsibility for the treatment and also attribute success to themselves appear to benefit more. Motivation is a crucial aspect of guided self-help in the treatment of depression.

Internet-based treatment of depression : a randomized controlled trial comparing guided with unguided self-help

Journal article (peer-reviewed)abstract
- 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. The present study compared the benefits of a 10-week web-based unguided self-help treatment with the same intervention complemented with weekly therapist support via e-mail. A waiting-list control group was also included. Seventy-six individuals meeting the diagnostic criteria of major depression or dysthymia were randomly assigned to one of the three conditions. The Beck Depression Inventory (BDI-II) was used as the primary outcome measure. Secondary outcomes included general psychopathology, interpersonal problems, and quality of life. Sixty-nine participants (91%) completed the assessment at posttreatment and 59 (78%) at 6-month follow-up. Results showed significant symptom reductions in both treatment groups compared to the waiting-list control group. At posttreatment, between-group effect sizes on the BDI-II were d = .66 for unguided self-help versus waiting-list and d = 1.14 for guided self-help versus waiting-list controls. In the comparison of the two active treatments, small-to-moderate, but not statistically significant effects in favor of the guided condition were found on all measured dimensions. 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.
