Konferensbidrag (refereegranskat)abstract
- Being highly attentive to details can be a positive feature. However, for some individuals, perfectionism can lead to distress and is associated with many psychiatric disorders. Cognitive behavior therapy has been shown to yield many benefits for those experiencing problems with perfectionism, but the access to evidence-based care is limited. The current study investigated the efficacy of guided Internet-based Cognitive Behavior Therapy (ICBT) and predictors of treatment outcome. In total, 156 individuals were included and randomized to an eight-week treatment or wait-list control. Self-report measures of perfectionism, depression, anxiety, self-criticism, self-compassion, and quality of life were distributed during screening and at post-treatment. Intention-to-treat were used for all statistical analyses. Moderate to large between-group effect sizes were obtained for the primary outcome measures, Frost Multidimensional Perfectionism Scale, subscales Concerns over Mistakes and Personal Standards, Cohen’s d = 0.68-1.00, 95% Confidence Interval (CI) [0.36-1.33], with 35 (44.9%) of the patients in treatment being improved. Predictors were also explored, but none were related to treatment outcome. In sum, guided ICBT can be helpful for addressing problems with clinical perfectionism, but research of its long-term benefits is warranted.

- Paradoxical intention (PI) has been considered an evidence-based treatment for insomnia since the 1990s, but it has not been evaluated with modern review techniques such as meta-analysis. The present study aimed to conduct the first systematic review and meta-analysis of studies that explore the effectiveness of PI for insomnia on insomnia symptomatology and theory-derived processes. A systematic review and meta-analysis was conducted by searching for eligible articles or dissertations in six online bibliographic databases. Randomised controlled trials and experimental studies comparing PI for insomnia to active and passive comparators and assessing insomnia symptoms as outcomes were included. A random effects model was estimated to determine the standardised mean difference Hedge's g at post-treatment. Test for heterogeneity was performed, fail-safe N was calculated, and study quality was assessed. The study was pre-registered at International Prospective Register of Systematic Reviews (PROSPERO, CRD42019137357). A total of 10 trials were identified. Compared to passive comparators, PI led to large improvements in key insomnia symptoms. Relative to active comparators, the improvements were smaller, but still moderate for several central outcomes. Compared to passive comparators, PI resulted in great reductions in sleep-related performance anxiety, one of several proposed mechanisms of change for PI. PI for insomnia resulted in marked clinical improvements, large relative to passive comparators and moderate compared to active comparators. However, methodologically stronger studies are needed before more firm conclusions can be drawn.

Experiences of Gamified and Automated Virtual Reality Exposure Therapy for Spider Phobia : Qualitative Study
- 2020
-
Ingår i: JMIR Serious Games. - Toronto, ON, Canada : JMIR Publications Inc.. - 2291-9279. ; 8:2
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Virtual reality exposure therapy is an efficacious treatment of anxiety disorders, and recent research suggests that such treatments can be automated, relying on gamification elements instead of a real-life therapist directing treatment. Such automated, gamified treatments could be disseminated without restrictions, helping to close the treatment gap for anxiety disorders. Despite initial findings suggesting high efficacy, very is little is known about how users experience this type of intervention.Objective: The aim of this study was to examine user experiences of automated, gamified virtual reality exposure therapy using in-depth qualitative methods.Methods: Seven participants were recruited from a parallel clinical trial comparing automated, gamified virtual reality exposure therapy for spider phobia against an in vivo exposure equivalent. Participants received the same virtual reality treatment as in the trial and completed a semistructured interview afterward. The transcribed material was analyzed using thematic analysis.Results: Many of the uncovered themes pertained directly or indirectly to a sense of presence in the virtual environment, both positive and negative. The automated format was perceived as natural and the gamification elements appear to have been successful in framing the experience not as psychotherapy devoid of a therapist but rather as a serious game with a psychotherapeutic goal.Conclusions: Automated, gamified virtual reality exposure therapy appears to be an appealing treatment modality and to work by the intended mechanisms. Findings from the current study may guide the next generation of interventions and inform dissemination efforts and future qualitative research into user experiences.

How well does internet-based CBT work for depression in Sweden? A patient-level meta-analysis
- 2023
-
Ingår i: Abstracts and Program Parallel Sessions. ; , s. 50-51
-
Konferensbidrag (refereegranskat)abstract
- Background: Several studies and meta-analysis suggest that ICBT works for patients with mild to moderate depression/depressive symptoms. Given the quality of the data is is now possible to conduct IPMAs. Several IPMAs have been published with data from different countries. A problem with that approach is the some studies may be left out as data are not provided. The aim of this IPMA was to study the effects focusing on Swedish data only with less loss of data/studies.Methods: We were able to include data from 16 studies with a total of 2952 participants. Missing data were imputed. The overall effect-size for nine studies compared to wait-list was d = 0.63 95 % CI [0.48, 0.78] and within-group effect-size for 15 studies d = 1.17 95 % CI [1.11, 1.22]. The results were surprisingly similar across different subgroups. Women had on average more symptoms before treatment and also reported a larger symptom decrease after treatment.Conclusions: Results show a large effect of ICBT on depressive symptoms in a Swedish setting, including in routine care. This meta-analysis supports treatment of depressive symptoms with ICBT in Sweden.

Internet‐delivered psychological treatments : from innovation to implementation
- 2019
-
Ingår i: World Psychiatry. - : Wiley. - 1723-8617 .- 2051-5545. ; 18:1, s. 20-28

Tidskriftsartikel (refereegranskat)abstract
- Internet interventions, and in particular Internet‐delivered cognitive behaviour therapy (ICBT), have existed for at least 20 years. Here we review the treatment approach and the evidence base, arguing that ICBT can be viewed as a vehicle for innovation. ICBT has been developed and tested for several psychiatric and somatic conditions, and direct comparative studies suggest that therapist‐guided ICBT is more effective than a waiting list for anxiety disorders and depression, and tends to be as effective as face‐to‐face CBT. Studies on the possible harmful effects of ICBT are also reviewed: a significant minority of people do experience negative effects, although rates of deterioration appear similar to those reported for face‐to‐face treatments and lower than for control conditions. We further review studies on change mechanisms and conclude that few, if any, consistent moderators and mediators of change have been identified. A recent trend to focus on knowledge acquisition is considered, and a discussion on the possibilities and hurdles of implementing ICBT is presented. The latter includes findings suggesting that attitudes toward ICBT may not be as positive as when using modern information technology as an adjunct to face‐to‐face therapy (i.e., blended treatment). Finally, we discuss future directions, including the role played by technology and machine learning, blended treatment, adaptation of treatment for minorities and non‐Western settings, other therapeutic approaches than ICBT (including Internet‐delivered psychodynamic and interpersonal psychotherapy as well as acceptance and commitment therapy), emerging regulations, and the importance of reporting failed trials.

Forskningsöversikt (refereegranskat)abstract
- Introduction: Internet-supported and therapist-guided cognitive behaviour therapy (ICBT) is effective for a range of problems in the short run, but less is known about the long-term effects with follow-ups of two years or longer.Areas covered: This paper reviews studies in which the long-term effects of guided ICBT were investigated. Following literature searches in PubMed and other sources meta-analytic statistics were calculated for 14 studies involving a total of 902 participants, and an average follow-up period of three years. Studies were from Sweden (n = 11) or the Netherlands (n = 3). Long-term outcome studies were found for panic disorder, social anxiety disorder, generalized anxiety disorder, depression, mixed anxiety and depression, obsessive-compulsive disorder, pathological gambling, stress and chronic fatigue. The duration of the treatments was usually short (8–15 weeks). The pre-to follow-up effect size was Hedge’s g = 1.52, but with a significant heterogeneity. The average symptom improvement across studies was 50%. Treatment seeking in the follow-up period was not documented and few studies mentioned negative effects.Expert commentary: While effects may be overestimated, it is likely that therapist-supported ICBT can have enduring effects. Long-term follow-up data should be collected for more conditions and new technologies like smartphone-delivered treatments.

Response and Remission Rates in Internet-Based Cognitive Behavior Therapy : An Individual Patient Data Meta-Analysis
- 2019
-
Ingår i: Frontiers in Psychiatry. - : Frontiers Media SA. - 1664-0640. ; 10

Forskningsöversikt (refereegranskat)abstract
- Background: Internet-delivered cognitive behavior therapy (ICBT) was developed over 20 years ago and has since undergone a number of controlled trials, as well as several systematic reviews and meta-analyses. However, the crucial question of response rates remains to be systematically investigated. The aim of this individual patient meta-analysis (IPDMA) was to use a large dataset of trials conducted in Sweden to determine reliable change and recovery rates across trials for a range of conditions.Methods: We used previously collected and aggregated data from 2,866 patients in 29 Swedish clinical trials of ICBT for three categories of conditions: anxiety disorders, depression, and others. Raw scores at pre-treatment and post-treatment were used in an IPDMA to determine the rate of reliable change and recovery. Jacobson and Truax’s, (1991) reliable change index (RCI) was calculated for each primary outcome measure in the trials as well as the recovery rates for each patient, with the additional requirement of having improved substantially. We subsequently explored potential predictors using binomial logistic regression.Results: In applying an RCI of z = 1.96, 1,162 (65.6%) of the patients receiving treatment were classified as achieving recovery, and 620 (35.0%) were classified as reaching remission. In terms of predictors, patients with higher symptom severity on the primary outcome measure at baseline [odds ratio (OR) = 1.36] and being female (OR = 2.22) increased the odds of responding to treatment. Having an anxiety disorder was found to decrease the response to treatment (OR = 0.51). Remission was predicted by diagnosis in the same direction (OR = 0.28), whereas symptom severity was inversely predictive of worse outcome (OR = 0.81). Conclusions: Response seems to occur among approximately half of all clients administered ICBT, whereas about a third reach remission. This indicates that the efficacy of ICBT is in line with that of CBT based in prior trials, with a possible caveat being the lower remission rates. Having more symptoms and being female might increase the chances of improvement, and a small negative effect of having anxiety disorder versus depression and other conditions may also exist. A limitation of the IPDMA was that only studies conducted in Sweden were included.

Knowledge About Treatment, Anxiety, and Depression in Association With Internet-Based Cognitive Behavioral Therapy for Adolescents : Development and Initial Evaluation of a New Test
- 2020
-
Ingår i: SAGE Open. - : Sage Publications. - 2158-2440. ; 10:1
-
Tidskriftsartikel (refereegranskat)abstract
- Evaluating knowledge and learning in psychotherapy is a growing field of research. Studies that develop and evaluate valid tests are lacking, however. Here, in the context of internet-based cognitive behavioral therapy (ICBT) for adolescents, a new test was developed using subject matter experts, consensus among researchers, self-reports by youths, and a literature review. An explorative factor analysis was performed on 93 adolescents between 15 and 19 years old, resulting in a three-factor solution with 20 items, accounting for 41% of the total variance. The factors were Act in aversive states, Using positive reinforcement, and Shifting attention. The internal consistency for the whole instrument was good (alpha = .84). Hopefully, the procedure presented here can contribute to the field by illustrating one way of evaluating knowledge in ICBT. The clinical use of the knowledge test needs further investigation.
