It has been an intense week for those involved in the treatment of OCD in children and adolescents. Fabian Lenhard has successfully defended his thesis, congratulations Fabian! His opponent was Professor John Piacentini from University of California, Los Angeles. Professor Piacentini is an experienced clinician and researcher in pediatric OCD. Yesterday he gave a lecture on the research frontiers in this field.
Internet-delivered CBT for adolescents with OCD
The topic of Dr. Lenhard’s thesis is Internet-delivered Cognitive Behavior Therapy for Adolescents with Obsessive-Compulsive Disorder. You can find the thesis here: https://openarchive.ki.se/xmlui/handle/10616/45535
He has developed and tested the treatment in an open trial and a randomized controlled trial. Analyses on cost-effectiveness and predictors of outcome are underway.
The results from both the open trial and the randomized trial indicate that internet-delivered CBT is an effective treatment for adolescents with OCD. The pre-post within-group effect sizes were large in both trials.

Professor John Piacentini: Optimizing Outcomes for Pediatric OCD
During his visit to Sweden, Professor Piacentini talked about research that aims to optimize outcomes in pediatric OCD. After receiving CBT, around 40 % of patients are in remission. While our treatments are effective for some, we still have a long way to go in order to treat every child and adolescent with OCD. Looking into specific mechanisms of change might be a way to optimize the current treatments.
Some suggested mechanisms include expectations of recovery (which might be mediated by home work compliance), the ability of a therapist to push exposures, and affect labeling (”I feel scared”) rather than cognitive restructuring during exposure.
Professor Piacentini also discussed recent work on neurotransmitters that directly target the underlying brain correlates of OCD. For example, glutamate levels might serve as a possible moderator of treatment outcome. We are awaiting the results from trials that aim to change glutamate levels pre-treatment to enhance the outcomes of CBT.

Internet-delivered cognitive behavior therapy for adolescents with obsessive-compulsive disorder

Thalia Eley is professor of developmental behavioural genetics at SGDP centre, Institute of psychiatry, King’s College, London. She is also head of EDIT lab where the research focuses on the genetic and environmental effects on development and treatment of anxiety and depression amongst children.

Rayner outside EDIT lab.
The EDIT lab team aim to explore why anxiety and depression disorders to some extend run in the family. On one hand they do twin studies to explore how much of variation in a phenotype, i.e. anxiety disorders, could be explained by genetic variance and on the other hand they perform studies on environmental factors to explore to what extent variation could be explained by nurture.
The BioPoRT project is a part of IAPT (Increasing access to psychological treatment) in the UK. The aim of BioPoRT is to find predictors for treatment outcome, exploring both demographic variables as well as clinical and genetic factors. The latter is called therapygenetics, a term coined by Thalia Eley a few years ago.
Additionally the team do research on information processing.
We got a tour of the actual lab by the centre laboratory manager Bernard Freeman, where the whole genome sequencing (GWAS) is being executed. He showed us DNA extracted from salmon sperm and some very high tech machinery.

The team also run the EDIT lab blog, a great source for novel research, interesting chronicles about bringing research into daily life hazzle (such as making your baby sleep) and the challenges one could face when working as a researcher.
Much of the work done at EDIT lab is related to the genetics work done at Rücklab, although our experience and knowledge in the field is a bit more scant. We look forward to future collaborations with the EDIT lab team.
Sabina Brohede of Linköping University has just defended the first ever dissertation on Body Dysmorphic Disorder ever. Congratulations Sabina! Below her work explained in 4 wooden figures.
Hi! My name is Oskar Flygare and I’m the latest addition to the group of PhD students at Rücklab. I have been working in the group for a year and am now a registered doctoral student with Christian Rück as main supervisor. Co-supervisors are David Mataix-Cols and Erik Andersson.
The focus of my PhD thesis is the psychological treatment of OCD
Lina Lundström and I are the project managers of a randomised controlled trial that compares two types of internet-delivered cognitive behavioural therapy (ICBT) with face-to-face cognitive behavioural therapy for adults with OCD. The three treatments are:
- Individual face-to-face CBT
- Therapist-guided ICBT
- Self-guided ICBT
120 individuals will be randomised to receive one of the treatments, i.e. 40 patients in each treatment arm. Treatment lasts for 14 weeks. We are recruiting participants and you can register here.
Our main goal is to evaluate the treatments on how well they provide symptom relief. In addition to this, I will also perform cost-effectiveness analyses on the three treatments, i.e. evaluate the benefits in relation to costs. My study plan also contains research on predictors and moderators of treatment outcome.
When I’m not doing a deep-dive in obscure research, I enjoy playing and listening to music. I have been playing the saxophone for 15 years and wanted to become a professional musician when I was a teenager. I came to my senses after three years of intense music studies in high school and switched to psychology.
Please get in touch if you want to exchange ideas or talk about interesting research! I am always curious, sometimes thoughtful and never indifferent.
Dr. Blake F. Dear, Co-Director of the eCentreClinic in Australia, recently visited Karolinska Institutet to partake in the dissertation of Marianne Bonnert. While in Sweden, he also gave a talk on recent updates from the Australian eCentreClinic. They develop internet-delivered psychological treatments for common mental health and physical health conditions.
We have just opened up our treatment study of internet-based cognitive behavioural therapy for international participants. The treatment is in English. Read more about it at: https://bddstudy.com
D-cycloserine (DCS) is a partial NMDA agonist that facilitates fear extinction in animals and reduces return of fear when given before extinction training. Despite several initial trials showing promising results in humans with anxiety disorders larger trials conducted within the past 5 years have produced mixed results. Our large trial in obsessive-compulsive disorder22 found no general effect of DCS but a significant interaction effect between DCS and antidepressant medication in a post hoc analysis; antidepressants impaired treatment response in patients randomized to DCS but not in patients randomized to placebo.
We collected Individual participant data for 21 of 22 DCS trials, representing 1047 of 1073 eligible participants. When controlling for antidepressant use, participants receiving DCS showed greater improvement from pretreatment to posttreatment (mean difference, −3.62; 95% CI, −0.81 to −6.43; P = .01; d = −0.25) but not from pretreatment to midtreatment (mean difference, −1.66; 95% CI, −1.60 to 4.92; P = .32; d = −0.14) or from pretreatment to follow-up (mean difference, −2.98, 95% CI, −0.03 to 5.99; P = .05; d = −0.19). Only 1 significant moderator emerged: year of publication. Specifically, the more recent the study, the smaller the difference between DCS and placebo for pretreatment to follow-up improvement (b = 4.02; 95% CI, 0.59-7.45; P = .02, d = 0.26).
Conclusion: D-cycloserine is associated with a small augmentation effect on exposure-based therapy. The small size of the effect makes the clinical usefulness of DCS doubtful.
