- Although cognitive interventions for obsessive-compulsive disorder (OCD) have been tested in randomized trials, there are few trials that have tested the specific mechanisms of cognitive interventions, i.e. how they achieve their effects. In this study, we aimed to investigate the mediating effects of a short cognitive intervention in the treatment of OCD and used data from a recently conducted randomized controlled trial where 101 participants were allocated to either Internet-based CBT (ICBT) or to a control condition. Obsessive beliefs were measured at pre-treatment, at the time they had received the cognitive intervention, and also at post-treatment. Weekly OCD symptoms were measured throughout the 10 weeks of treatment. We hypothesized that (1) the ICBT group would have greater reductions in obsessive beliefs (controlling for change in OCD symptoms) after completing the cognitive intervention, and that (2) this reduction would, in turn, predict greater OCD symptom reduction throughout the rest of the treatment period. Contrary to our expectations, the longitudinal mediation analysis indicated that (1) being randomized to ICBT actually increased the degree of obsessive beliefs after receiving the cognitive intervention at weeks 1-3, and (2) increase in obsessive beliefs predicted better outcome later in treatment. However, when repeating the analysis using cross-sectional data at post-treatment, the results were in line with the initial hypotheses. Results were replicated when the control condition received ICBT. We conclude that, although obsessive beliefs were significantly reduced at post-treatment for the ICBT group, early increase rather than decrease in obsessive beliefs predicted favourable outcome.

- 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.

Advantages and limitations of Internet-based interventions for common mental disorders

Tidskriftsartikel (refereegranskat)abstract
- Several Internet interventions have been developed and tested for common mental disorders, and the evidence to date shows that these treatments often result in similar outcomes as in face-to-face psychotherapy and that they are cost-effective. In this paper, we first review the pros and cons of how participants in Internet treatment trials have been recruited. We then comment on the assessment procedures often involved in Internet interventions and conclude that, while online questionnaires yield robust results, diagnoses cannot be determined without any contact with the patient. We then review the role of the therapist and conclude that, although treatments including guidance seem to lead to better outcomes than unguided treatments, this guidance can be mainly practical and supportive rather than explicitly therapeutic in orientation. Then we briefly describe the advantages and disadvantages of treatments for mood and anxiety disorders and comment on ways to handle comorbidity often associated with these disorders. Finally we discuss challenges when disseminating Internet interventions. In conclusion, there is now a large body of evidence suggesting that Internet interventions work. Several research questions remain open, including how Internet interventions can be blended with traditional forms of care.

Forskningsöversikt (refereegranskat)abstract
- In recent years, there has been an increased interest in the cognitive foundations of religion and experimental methods have been used to explain religious behaviours. However, in the world, there are a substantial number of non-believers (atheists), and this has been a largely unknown field for experimental and more basic research informed by cognitive science. This has now changed and in this review, I cover three domains of study. First, studies in which belief in God has been manipulated in the direction of showing less belief are reviewed. For example, it is shown that analytical thinking reduces religious belief. Second, recent studies on cognitive bias against atheists are covered showing that atheists are distrusted, elicit disgust and are viewed as immoral both explicitly and implicitly. Third, I review studies in which prejudice against atheists has been experimentally manipulated showing that it is possible to reduce bias against atheists. I conclude the paper arguing that the bias against atheists need to be investigated in the Scan-dinavian countries.

Autobiographical Memory Specificity in Patients with Tinnitus Versus Patients with Depression and Normal Controls
- 2013
-
Ingår i: Cognitive Behaviour Therapy. - : Taylor and Francis (Routledge): STM, Behavioural Science and Public Health Titles / Taylor and Francis (Routledge). - 1650-6073 .- 1651-2316. ; 42:2, s. 116-126

Tidskriftsartikel (refereegranskat)abstract
- Several studies show that patients with depression and post-traumatic stress disorder respond with fewer specific autobiographical memories in a cued memory task (i.e. the autobiographical memory test; AMT) compared to healthy controls. One previous study found this phenomenon among tinnitus patients as well (Andersson, Ingerholt, andamp; Jansson, 2003). The aim of this study was to replicate the previous study with an additional control group of depressed patients and memory errors as measured with the AMT as an additional outcome. We included 20 normal hearing tinnitus patients, 20 healthy controls and 20 persons diagnosed with clinical depression. The AMT was administered together with self-report measures of depression, anxiety and tinnitus distress. Both the tinnitus and depression groups differed from the healthy control group in that they reported fewer specific autobiographical memories. There were, however, differences between the tinnitus and depression groups in terms of the errors made on the AMT. The depression group had more overgeneral memories than the normal control group, whereas the tinnitus group did not differ from the control group on this memory error. The tinnitus group had more semantic associations and non-memories than the other two groups, suggesting that executive functioning may play a role for the tinnitus group when completing the AMT. Clinical and theoretical implications of the findings are discussed.

Can the patient decide which modules to endorse? : an open trial of tailored internet treatment of anxiety disorders
- 2011

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.
