An interventional study of Cognitive behavior therapy and Internet support in Hoarding Disorder, sponsored by Karolinska Institutet. Completed at 1 site in Sweden. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2017-08-18.
Sponsored by Karolinska Institutet · Not applicable, Interventional, and Treatment
The primary aim is to develop, and test the feasibility and efficacy of, a manual based, cognitive behaviour therapy (CBT) treatment for Hoarding Disorder (HD) delivered in a group format combined with an Internet support system. The investigators' secondary aim is to investigate the neurocognitive profile of the participants before and after treatment in order to explore if the treatment might have an impact on neurocognitive functioning and if certain neurocognitive profiles predict outcome.
For the primary aim, the investigators hypothesize that the treatment will be acceptable to participants and decrease symptoms of hoarding. Regarding the secondary aim, the investigators hypothesize that deficiencies in executive functioning, as measured with a neurocognitive battery, will reduce upon completion of treatment and that baseline executive function will be associated with treatment outcome.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Ran from Oct 2015 to primary completion in Jun 2017, 20 months.
Of 20 interventional studies with no phase under Hoarding Disorder, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 48. This study's 20 months is below that.
