Individuals with Hoarding disorder (HD) have on-going difficulties in discarding possessions, and it is now considered to be a mental health disorder. Previous assessments of Hoarding Disorder have not been very accurate, so a new assessment tool was developed called The Structured Interview for Hoarding Disorder (SIHD). This paper looked at how effective the SIHD is as an assessment of Hoarding Disorder.

How was the study conducted?

Participants were recruited from the South East London Community Health (SELCoH) study, a two-phase study of two diverse London boroughs. Out of the 1698 participants from the first phase of SELCoH, 191 participants were seen to be suitable to be assessed for HD in a follow-up study. Out of the 191 suitable participants, 99 individuals (55% female) aged between 16 and 77 years, took part in the SIHD interview and were assessed for HD.

A diagnosis of HD was given if there was agreement between specialists in HD, which included three researchers and a psychiatrist.  

What did we find?

Using the SIHD interview, the raters strongly agreed that HD was present in 16 individuals (16.2% of the 99 individuals who were interviewed because they were identified as being at greater risk of having a hoarding disorder). 8 were female and 8 were male, with their ages ranging between 23 and 74 years.

The strong agreement between raters in diagnosing Hoarding Disorder using the SIHD shows it is an accurate and reliable assessment measure of HD.


The results show that the SIHD provides a good assessment of HD. Ideally, the SIHD should be completed in the person's home by experienced interviewers, and should include all available sources of information. As the SIHD can also assess for risk, it can be useful in helping identify individuals who are at risk of HD.
