The Experience of Emotional Distancing in The Management of Compulsive Hoarding: A Visual Methods Approach Using The “Hoard” Acronym Tool

“Conclusion: Emotional distancing occurs during these reflective activities, with seems to play an important role when utilizing the “HOARD” acronym tool.  Three key themes emerged from the data:  the evocative power of the image,  images as monitoring tools and verifying and validating the hoarding problem.  This particular methodological approach is beneficial in generating valuable narrative for self-reflection.”

Understanding  Hoarding in Vancouver’s downtown eastside

"A separate arm of the project is to get a sense of the prevalence of hoarding in
the Downtown Eastside neighbourhood, which has many supportive housing buildings.

A previous study by a community group in the neighbourhood involved a survey of
landlords and building managers and suggested a very high prevalence rate - up to
four times as high as estimates for the general population"

Is Hoarding a Symptom of Obsessive-Compulsive Disorder?
"The presence of hoarding symptoms in patients with obsessive-compulsive disorder (OCD)
is a commonly reported phenomenon. How these symptoms are to be understood is less clear.
The extent to which hoarding fits with other symptoms of OCD by considering its diagnostic
utility and underlying cognitive processes is evaluated. In the first study, hoarding symptoms
did not differentiate OCD patients from individuals with other anxiety disorders or unscreened
students, indicating that hoarding does not inform diagnostic decision making. In the second study,
using an independent nonclinical sample, cognitive variables related to OCD were distinct from
hoarding-specific cognitions, and not predictive of hoarding symptoms. These results add to a
growing body of evidence suggesting that hoarding is not a symptom or manifestation of OCD.
The need for careful assessment of the function of hoarding symptoms is discussed"

Psychiatric Issues in Hoarding - Strategies for Diagnosing and Treating Symptoms of Hoarding

"Historically, hoarding has been deemed a subtype of OCD, although forthcoming evidence
suggests there are more differences than similarities. Hoarding is under consideration for
inclusion in DSM-5 as a stand-alone disorder. A set of provisional criteria for hoarding disorder
has been proposed and will require further study in the future. A recent study conducted by
Frost and colleagues that examined the largest sample of participants to date confirmed that
major depressive disorder was the most frequently occurring comorbid condition (more than 50%)
and that kleptomania was a factor in 10% of the sample. This article highlights treatment options
for hoarding that are available to practitioners, including alternative approaches focusing on
self-help, support group, and Web-based delivery models."..........

ADHD prevalence and association with hoarding behaviors in childhood-onset OCD.
CONCLUSION: ADHD rates were elevated in this sample of individuals with childhood-onset OCD
compared to the general population rate of ADHD, and there was a strong association between
ADHD and clinically significant hoarding behavior. This association is consistent with recent studies
suggesting that individuals with hoarding may exhibit substantial executive functioning impairments
and/or abnormalities, including attentional problems

REVIEW: HOARDING DISORDER: A NEW DIAGNOSIS FOR DSM-V?
See the full article and research at the link below.
One of the conclusions and preliminary recommendations:
1. Clinically significant hoarding is prevalent and can
vary from mild to life threatening. The personal and
public health consequences of hoarding are substantial and it is generally considered difficult to
treat. These direct and indirect consequences of
hoarding are serious enough to warrant its consideration as a mental disorder
............
10. If it becomes a separate diagnostic category, the most appropriate ‘‘neighborhood’’ for hoarding
disorder is unclear as it has ties with several groupings of disorders, particularly OCD and
impulse control disorders. Until we learn moreabout its etiology, the decision will necessarily
require expert consensus. For the time being, giventhe historical link between hoarding and OCD/
OCPD, the fact that some hoarders are seen in OCD clinics, and the conservative approach adopted
by DSM-V, it would be reasonable to acknowledge hoarding disorder as an OCSD, if such a group is
included in DSM-V. An alternative to our recommendation would be to include it in an Appendix of
Criteria Sets Provided for Further Study.

Hoarding as a Behavioral Addiction
"Compulsive hoarding is a psychiatric syndrome with serious personal and public health consequences.
Although the diagnostic status of hoarding is uncertain, it appears to be associated with a number of
other psychiatric disorders, including obsessive-compulsive disorder. Several important features of
hoarding, however, differentiate it from obsessive-compulsive disorder and other anxiety disorders.
Moreover, there are important phenomenological similarities between hoarding and behavioral addictions,
such as the pleasurable feelings that may be associated with collecting and saving. In this chapter, we
review diagnostic and comorbidity issues regarding hoarding, while highlighting the relationship between
hoarding and impulse control disorders. In addition, we discuss ways in which a behavioral addiction model
may be consistent with compulsive hoarding. We also outline a prominent cognitive-behavioral theoretical
model of hoarding that emphasizes the role of both information-processing deficits and excessive emotional
attachment to possessions. Finally, we describe various self-report and interview measures used to assess
hoarding, as well as current biological and psychological approaches to treatment"

"Conclusion: The prevalence and clinical characteristics of compulsive hoarding in OCD subjects
was similar to those reported in Western countries, supporting its trans-cultural consistency.
The distinction between primary and secondary hoarding in OCD is clinically useful, and may
contribute to the debate about whether hoarding should be a separate diagnostic entity."

Compulsive Hoarding : an interpretive phenomenological analysis                                                       Abstract:                                                                                                                                                                                                            
Background:
This project aimed to explore the experiences of people who compulsively hoard
and how they make sense of their own hoarding behaviours.

Method:
A total of 11 compulsive hoarders were recruited and interviewed using a simple semi-structured
interview format, designed for the purposes of the study. The resulting transcribed interviews were analyzed using
interpretive-phenomenological analysis.

Results
: Four super-ordinate discrete, but interacting, themes were found: (1) childhood factors; (2) the participants'
relationship to their hoarded items; (3) cognitive and behavioural avoidance of discard; and (4) the impact of
hoarding on self, others and the home environment. The themes as a whole described people entrapped in
massively cluttered physical environments of their own making. Efforts at discard appeared consistently
sabotaged by cognitive/behavioural avoidance, thereby creating maintaining factors of associated personal
distress and environmental decline.

Conclusions:
The results are discussed in the context of the extant evidence concerning hoarding, the distinct
contribution made by the current results and the identified methodological shortcomings of the research approach.

Family Informants' Perceptions of Insight in Compulsive Hoarding
"Family/friend informants’ ratings of hoarding severity were significantly greater than were their estimates
of the hoarder’s ratings. Hoarders described as showing less distress about the hoarding were described
as showing poorer insight. These results suggest that compulsive hoarding is characterized by poor insight
into the severity of the problem. Treatment development might need to emphasize strategies to bolster
awareness, insight, and motivation."

Elucidating the Relationship of Hoarding to Obsessive Compulsive Disorder and Impulse Control Disorders
"Therefore, the current study tested the hypothesis that hoarding would be as strongly related to symptoms
of ICDs as it is to OCD and that these relationships would be medium to strong in magnitude. Results from
an undergraduate sample showed hoarding behaviors were strongly related to symptoms of OCD, moderately
related to symptoms of compulsive buying, and more modestly related to symptoms of pathological gambling,
trichotillomania, and kleptomania. Finally, findings suggest indecisiveness may be a particularly important
underlying feature in hoarding behaviors. These results support the consideration of hoarding outside the confines
of OCD."

Recent Advances in Compulsive Hoarding
Abstract
"Compulsive hoarding is a common and often disabling neuropsychiatric disorder. This article reviews the
conceptualization, phenomenology, diagnosis, etiology, neurobiology, and treatment of compulsive hoarding.
Compulsive hoarding is part of a discrete clinical syndrome that includes difficulty discarding, urges to save,
excessive acquisition, indecisiveness, perfectionism, procrastination, disorganization, and avoidance. It was
thought to be part of obsessive-compulsive disorder or obsessive-compulsive personality disorder, but recent
evidence indicates that it should be classified as a separate disorder with its own diagnostic criteria. Compulsive
hoarding is a genetically discrete, strongly heritable phenotype. Neuroimaging and neuropsychological studies
are elucidating its neurobiology, implicating dysfunction of ventral and medial prefrontal cortical areas that
mediate decision-making, attention, and emotional regulation. Effective treatments include pharmacotherapy
and cognitive-behavioral therapy. More research will be required to determine the prevalence, etiology, and
pathophysiology of compulsive hoarding and to develop better treatments."

Development and Validation of Clutter Image Rating
"Few instruments are available to assess compulsive hoarding and severity of clutter. Accuracy of assessment
is important to understanding the clinical significance of the problem. To overcome problems associated with
over- and under-reporting of hoarding symptoms, the clutter image rating (CIR) was developed. This pictorial
scale contains nine equidistant photographs of severity of clutter representing each of three main rooms of
most people’s homes: living room, kitchen, and bedroom. The psychometric properties of this measure were
examined in two studies. Internal consistency, test–retest, and interobserver reliabilities were good and
convergent validity with other questionnaire and interview measures was also good. The CIR correlated more
strongly with measures of clutter than with other hoarding and psychopathology scales. The CIR’s very brief
pictorial assessment method makes it useful in clinical and treatment contexts for measuring the clutter
dimension of compulsive hoarding. Development and Validation of the Clutter Image Rating"

Hoarders' Scans Reveal Distinct Brain Signature.
Am J Psychiatry. 2004 June;161(6):1038-48.
"Recent positron emission tomography (PET) imaging studies by scientists at the University of California at Los Angeles
suggest that the neurobiology of America's estimated 1 million compulsive hoarders differs significantly from people
with other obsessive-compulsive disorder (OCD) symptoms as well as healthy individuals. The findings also suggest
that hoarders might respond best to medications that target particular brain systems. The study by Sanjaya Saxena, M.D.,
and colleagues detected less brain activity in the anterior cingulate gyrus of compulsive hoarders than in other OCD
patients. This brain structure helps govern decision-making, focused attention, motivation, and problem solving ? cognitive
functions that frequently are impaired in compulsive hoarders. The study also found a correlation in all of the subjects
with OCD between the severity of hoarding symptoms and lower brain activity in the anterior cingulate gyrus.
