- Background. Cognitive behaviour therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD) but access to CBT is limited. Internet-based CBT (ICBT) with therapist support is potentially a more accessible treatment. There are no randomized controlled trials testing ICBT for OCD. The aim of this study was to investigate the efficacy of ICBT for OCD in a randomized controlled trial. less thanbrgreater than less thanbrgreater thanMethod. Participants (n=101) diagnosed with OCD were randomized to either 10 weeks of ICBT or to an attention control condition, consisting of online supportive therapy. The primary outcome measure was the Yale-Brown Obsessive Compulsive Scale (YBOCS) administered by blinded assessors. less thanbrgreater than less thanbrgreater thanResults. Both treatments lead to significant improvements in OCD symptoms, but ICBT resulted in larger improvements than the control condition on the YBOCS, with a significant between-group effect size (Cohens d) of 1.12 (95% CI 0.69-1.53) at post-treatment. The proportion of participants showing clinically significant improvement was 60% (95% CI 46-72) in the ICBT group compared to 6% (95% CI 1-17) in the control condition. The results were sustained at follow-up. less thanbrgreater than less thanbrgreater thanConclusions. ICBT is an efficacious treatment for OCD that could substantially increase access to CBT for OCD patients. Replication studies are warranted.

- The Dimensional Obsessive-Compulsive Scale (DOCS) was designed to address the current limitations of existing obsessive-compulsive (OC) symptom measures and is a self-report questionnaire that assesses the severity of the four most empirically supported OC symptom dimensions. The aim of this study was to examine the psychometric properties of a Swedish version of the DOCS when administered via the Internet. Internal consistency, factor structure, and convergent and discriminant validity were examined in a sample consisting of 101 patients diagnosed with obsessive-compulsive disorder. The DOCS sensitivity to treatment effects were examined in a sample consisting of 48 patients treated with Internet-delivered cognitive behavioral therapy were the main intervention was exposure with response prevention. Results showed that the internal consistency was high. The DOCS also showed adequate convergent and discriminant validity, as well as fair sensitivity to treatment effects. The factor analysis supported the DOCS four-factor solution. In summary, the results from the present study give initial support that the DOCS can be administered via the Internet with adequate psychometric properties. © 2012 Elsevier Ltd.

Consensus statement on defining and measuring negative effects of Internet interventions
- 2014

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Internet interventions have a great potential for alleviating emotional distress and promoting mental health. A number of clinical trials have demonstrated their efficacy for several psychiatric conditions, and Internet interventions will likely become a common alternative to face-to-face treatments. Meanwhile, research has paid little attention to the potential negative effects associated with treatment, warranting further investigation of the possibility that some patients might deteriorate or experience adverse events. Evidence from face-to-face treatments suggests that negative effects afflict 5-10% of all patients undergoing treatment in terms of deterioration alone. However, there is currently a lack of consensus on how to define and measure negative effects in psychotherapy research in general, leaving researchers without practical guidelines for monitoring and reporting negative effects in clinical trials.Method: The current paper seeks to provide recommendations that could promote the study of negative effects in Internet interventions with the aim of increasing the knowledge of its occurrence and characteristics. Ten leading experts in the field of Internet interventions were invited to participate and share their perspective on how to explore negative effects, using the Delphi technique to facilitate a dialogue and reach an agreement.Results: The importance of conducting further research on negative effects is emphasized, and suggestions on how to classify and measure negative effects in Internet interventions are provided, involving methods from both quantitative and qualitative research. Potential mechanisms underlying negative effects are also presented, differentiating common factors shared with face-to-face treatments from those unique to treatments delivered via the Internet.Conclusion: Negative effects are to be expected and need to be acknowledged to a greater extent, advising researchers to systematically probe for negative effects whenever conducting clinical trials involving Internet interventions, as well as to share their findings in scientific journals.
