About this trial
Hoarding disorder is characterized by excessive amassment of objects in the home and difficulty of getting rid of the objects. It is associated with a high level of somatic and psychiatric comorbidity, suicidality, social marginalization, damage to property and risk of eviction. Previous clinical studies have mainly been in help-seeking groups. However, social services engage severe cases with poor insight, whereas few as 10% have contact with mental health services.
This study investigates:
1. The prevalence of severe mental illness and comorbidities among 60 individuals with hoarding disorder that have led to contact with social services at Copenhagen Municipality 2. the effect of a cross-sectoral intervention aiming to establish contact with regional mental health services for these individuals. The intervention consists of an outreach team of clinicians and municipal social workers who refer participants to clinical services based on a systematic clinical assessment.
Primary outcomes are 1) primary and comorbid diagnoses assigned at the clinical assessment and 2) contact with mental health services after the intervention, at 3- and 6-months follow-up.
Six to 12 months after the baseline assessment, a qualitative follow-up interview will be carried out, including approximately 14 participants. The aim is to explore the participants' experience of the intervention and subsequent clinical and social services to provide a more nuanced understanding of the quantitative outcomes of the study.
The hypotheses of the study are
1. more than 75% of the participants will be identified to have comorbid diagnoses including more than 50% with associated severe mental illness (schizophrenia, other psychotic disorders, bipolar disorder and periodic depression). It is expected that 10% will suffer from underlying organic disorders of dementia or mental retardation. 2. Fifty percent of the sample will establish contact with mental health services within 3 months after attempt of referral, and 30% of the sample will remain in contact for more than 6 months

Treatments tested in this trial
Assertive and supportive diagnostic detection team
Diagnostic testThe intervention consists in an outgoing (assertive and flexible) team of clinicians (the PhD student, primary supervisor and co-supervisor who are both clinical associate professors and senior consultants) and municipality social workers, directed towards people with hoarding disorder and an ongoing contact with The Housing Advisors, Copenhagen Municipality. The clinicians will do the clinical assessment, and based on this, the team facilitates referrals of research participants to the appropriate regional mental health services, if referral is relevant. The task of the social workers in the intervention will be the same as their current function in The Housing Advisors as outgoing case managers regarding the social issues of their clients.

Trial outcomes
Primary outcomes
1
Primary and comorbid psychiatric diagnosis
ICD-10, ICD-11 and DSM-5 diagnoses
Time frame
Primary and comorbid diagnosis is assessed at baseline.2
Contact or not with mental health services at a 3- and 6-months follow up
Data obtained through review of files and Nationwide register-data from the National Patient Register and Danish Psychiatric Central Register
Time frame
The participants get referred at baseline, and contact or no contact will be measured at 3 and 6 months follow-upSecondary outcomes
1
Clutter Image Rating Scale (CIR)
Photographic self-measurement scale. The participant have to look at a photographic scale for 3 types of rooms which is living room, kitchen and bedroom. The score goes from one to nine, and the participants has to choose the photo that is closest to being accurate. The higher the score, the worse the outcome.
Time frame
Assessed at baseline and 3- and 6-months follow-up.2
Saving Inventory - Revised (SIR)
Self-rating measure consisting of 23 items, subdivided in 3 subscales with 7-9 items in each. The scale goes from 0 to 4. The higher the score, the worse the outcome. The subscales are: Clutter Subscale (9 Items) Difficulty Discarding/ Saving Subscale (7 items) Acquisition Subscale (7 items) The total score is the sum of all items.
Time frame
Assessed at baseline and at 6 months follow-up3
Manchester Short Assessment of Quality of life (MANSA)
Quality of life self-rating scale. The participants have to answer 15 questions on a Likert-scale from 1-7, where one is the worst and seven is the best. The lower the score, the worse the outcome.
Time frame
Assessed at baseline and at 6-months follow-up4
Home Environment Assessment Tool for Hoarding (HEATH)
Clinician-rated scale assessing the home for health and safety risks. Consists of five subscales, which will be rated from zero to two. Zero is low risk and 2 is high risk. The total score is the sum of the five subscales. The higher the score, the worse the outcome.
