Forskningsstudie för vuxna med tvångssyndrom

IKBTvsF2F_reklam

Lider du av tvångssyndrom? Just nu bedriver vi en studie där vi jämför olika varianter av KBT-behandling vid tvångssyndrom. Rekryteringen är öppen hela 2017 och det är gratis att delta i studien.

Den som deltar i studien blir lottad till en av tre KBT-behandlingar, som alla pågår i 14 veckor:

  • Behandling på OCD-programmet (Huddinge Sjukhus)
  • Internet-behandling med behandlarstöd
  • Internet-behandling på egen hand

Före och efter behandlingen får deltagarna komma till Huddinge Sjukhus för utvärdering. Vi gör också uppföljningar 3 och 12 månader efter behandlingen.

Largest study on hoarding symptoms

This week, our latest study on hoarding symptoms in young people was published in Plos One. In this study, we used data from the Swedish Twin Registry  on twins in 3 samples (ages 15, 18 and 20-28 years). We had access to data for more than 16 000 twins (largest sample to date) and estimated the heritability at every age and also conducted longitudinal analyses on twins with data at ages 15 and 18. Our results showed that hoarding symptoms were heritable at all ages although the heritability decreased somewhat with age. Symptoms of hoarding were also moderately stable between ages 15 and 18, and this stability was largely due to genetic factors while non-shared environmental factors had a time-specific effect.

It’s done.

Manuel Mattheisen joins our group

Our collaborator Manuel Mattheisen, Associate Professor at Århus University, is now officially affiliated to Karolinska Institutet and our group.  He studied medicine at the University in Bonn and went on to be a research follow at Harvard Medical School before moving to Denmark. We are fortunate to enjoy his deep expertise in genetical methods. Check out his quite spectacular publication list here.

A strong week for CBT-treatment of pediatric OCD

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.
