New radio documentary miniseries “Hoarders”!

The new radio documentary miniseries “Hoarders” is now available on Swedish Radio P1. Hoarders is a three-part docuseries following people suffering from hoarding-related problems, exploring available remedies and support, and including the perspective of close relatives to hoarders. Volen Ivanov is featured in the documentary to lend his perspective on hoarding and provides information on effective types of treatment. 

In connection with the release of the first episode, Volen Ivanov was also featured alongside documentary director David Ohlsson, and Hanna Danmo in Studio One to give more information on the documentary miniseries as well as provide more insight into the problem both from the clinical and practical perspective, which can be listened to here.

Hoarding disorder is still relatively understudied, and it is believed that as many as 2,5 % of the population suffers from it. It is promising that hoarding has been spotlighted over the past couple of months, including in the SVT documentary Samlarna, released earlier this year. We are still actively recruiting for our study, testing a new treatment for patients with hoarding disorder. Read more about the study, and about how to apply, here.

All three episodes are available on Swedish public radio (Sveriges radio) and can be accessed by clicking the links below. All episodes are in Swedish. 

Science, Samba & Soccer: our visit to São Paulo in August 2022

Last week, Oskar Flygare, Volen Ivanov and Christian Rück visited our collaborators in São Paulo, Brazil to work on current projects and discuss new ones. This was the third meeting in person between the two collaborating groups, the previous ones being Alice de Mathis’ visit to Stockholm and a visit by Oskar and Christian to São Paulo in 2019. The OCD research group at São Paulo is led by professor Euripedes Constantino Miguel and our visits always involve a rich exchange of ideas relating to our research.


One ongoing research project is a pilot study of an internet-delivered treatment for obsessive-compulsive disorder (OCD-NET) which has been translated to Portuguese and is now being evaluated in Brazil. After a brief suspension due to the pandemic, the project is now well underway with ongoing recruitment and treatment of patients. So far the feedback from both therapists and patients has been encouraging. In addition to discussing the ongoing project, Oskar presented results and lessons learned from two recent clinical trials on OCD-NET in Sweden and England.

Volen shared his knowledge about hoarding disorder, from research projects and clinical work. Expertise in diagnosing and treating hoarding disorder is sorely lacking in Brazil, and our colleagues were eager to learn as much as possible in order to provide effective care. Interestingly, just months before our visit a podcast about an individual with likely hoarding disorder in São Paulo has stoked public interest and increased awareness about the condition. It is clear that our research groups have plenty of opportunities for collaboration on projects related to hoarding.

The visit was also an opportunity to plan an upcoming project led by Arthur Caye that will evaluate internet-delivered treatments for OCD, depression, insomnia and anxiety in two municipalities outside of São Paulo: Jaguariúna and Indaiatuba. The access to psychotherapy in these cities is limited and the project is an opportunity to increase access to effective treatments for common disorders. The project will evaluate the feasibility of using internet-delivered treatments in primary care, where most of the patients with mental disorders are seen.


We were once again moved by the hospitality and warmth our hosts showed us. There was a rich social programme outside the work activities and we had the opportunity to enjoy samba with Daniel Costa, soccer with Rodolfo Furlan Damiano and several restaurants together with our Brazilian colleagues Nil Morales, Sonia Borcato and Roseli Shavitt. Thanks to their generosity with their time, we got a true taste of Brazilian culture!

Two new research assistants needed

Interested in psychiatry research? Want to join the group? We are hiring not one but TWO new research assistants!

The group is certainly expanding. Team leader John Wallert just advanced to Assistant Professor within the group, congratulations! 🎯

We are also hiring two new research assistants for two slightly different employments.

One is for The Joining Forces RCT crew, working with Volen Ivanov and Sofia Jägholm. In this job you will do different tasks related to their RCT on a new combination treatment for hoarding disorder, including screening interviews and home visits with hoarding patients, interviews with housing supporters and managers in the social services and monitoring of data collection as well contact with the project’s various collaboration partners. Read more and apply here. Last day to apply is July 31.

The other one is for John Wallert’s interdisciplinary modeling team, an employment in a project in precision psychiatry. This employment includes assisting John and three others with tasks such as database work, archiving of completed projects, meeting documentation and planning, create and then support a structure for work in the steering group for one of our larger projects and write research information texts. Read more and apply here. Last day to apply is July 31.

2014 in review: highlights

Dear friends,

2014 has been a good year. We have contributed to 18 publications, presented at several congresses, Evelyn Andersson and Volen Ivanov have had their half-time seminars on their steady way to a PhD and Erik Andersson was the first out of our lab to defend his thesis. We have also staged what may be the Worlds first blind breaking party. On a more serious note, several of our treatment studies have helped people who suffer. We have published the first internetbased CBT study for Body Dysmorhic Disorder with Jesper Enander as first author and stay tuned for more on BDD in 2015. We hope to do even more in 2015. If you wish to donate to our research to make it possible, contact .

Oh yeah, he did it. Erik Andersson, PhD, being admired by Sabine Wilhelm and Christian Rück.

Volen Ivanov

On the radio: Om sjukligt samlande i P1

Idag talade bl a Volen Ivanov, Christian Rück och David Mataix-Cols som sjukligt samlande (hoarding) i P1:s Kropp och Själ som du kan lyssna på här:

Även HSB:s psykosociala enhet med Sylvia Mårtensson och Christina Ahlström berättar om deras fantastiska verksamhet i programmet.

Ny artikel: Om patologiskt samlande i Läkartidningen

Volen Ivanov och Christian Rück skriver i veckans nummer av Läkartidningen om patologisk samlande (hoarding). Att samla på saker är ett allmänmänskligt fenomen; studier har visat att 70 procent av barn och 30 procent av vuxna har en samling.
Men ibland kan samlandet ta sig orimliga proportioner och gå över gränsen till det sjukliga. Patologiskt samlande är svårigheter att göra sig av med saker på grund av ett upplevt behov att behålla dem och obehag förknippat med att göra sig av med dem. Symtomen resulterar i att hemmet blir stökigt och överhopat. Tillståndet är svårbehandlat, men vissa lovande resultat finns med läkemedelsbehandling och psykologisk behandling. Troligtvis krävs samordnade insatser från sjukvård, socialtjänst, bostadsbolag etc. Läs mer här.
