Enduring effects of ICBT
- 2017
-
Konferensbidrag (refereegranskat)abstract
- Introduction: Numerous randomized controlled trials have been conducted on internet interventions. In addition to the effects observed in these trials immediately after treatment there are several long-term follow-ups. The aim of this talk is to review the long-term effects of internet-delivered CBT (ICBT) with a focus on results at 1-year or later following treatment termination.Methods: We were able to locate examples of enduring effects for a range of conditions including mood and anxiety disorders and somatic disorders. The longest follow-up period has been five years.Results: Large within-group effects have been documented in most trials, with effects sizes being moderate to large for anxiety and depression studies.Discussion: Studies have failed to document how much the treatment is used during the follow-up period and in the case of depression it is unclear if episodes of depression have occured during the period covered. We conclude that the effects of ICBT appear to be enduring but that more research is needed.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Numerous controlled trials have been published on the effects of internet-delivered psychological treatments for a range of problems and disorders. Generally, trials adhere to the CONSORT statement and include control groups. Often this is attention control, waitlist but also alternative treatments. In experimental psychology factorial designs is the common way to investigate research questions but in psychotherapy research this is rare given the need for large samples in order to have sufficient power to detect differntial effects of independent variables (like for example different versions of a treatment). With the advent of internet-delivered CBT (ICBT) this has changes and it is now possible to run trials with larger samples. At the same time there is really no need for more studies showing that a treatment is better than just waiting (for some areas at least like depression). In this talk we will present result from three completed factorial design trials in which we have manipulated support form (on demand versus scheduled in one trial and chat-support versus just email in another), and also other aspects like learning support and choice of treatment. The talk will end with a discussion on future directions of ICBT research with regards to design of trials.

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.

Konferensbidrag (refereegranskat)abstract
- Internet-delivered cognitive behaviour therapy (ICBT) has been tested in many research trials but to a lesser extent been directly compared against face-to-face delivered cognitive behaviour therapy (CBT). We conducted a systematic review and meta-analysis on trials in which guided ICBT was directly compared against face-to-face CBT within the same trial. Studies on psychiatric and somatic conditions were included. Systematic searches resulted in 13 studies (total N=1053) that met all review criteria and were included in the review. There were 3 studies on social anxiety disorder, 3 on panic disorder, 2 on depressive symptoms, 2 on body dissatisfaction, 1 on tinnitus, 1 on male sexual dysfunction, and 1 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 at post-treatment across of Hedges g = -0.01 (95% CI, -0.13 to 0.12), indicating that 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 for which guided ICBT has not been compared against face-to-face treatment. Thus, more research is needed to establish equivalence of the two treatment formats.
