Nick Cave, an American fabric sculptor and performance artist, is best known for his Soundsuits—ie, wearable sculptural forms that transform ordinary objects into whimsical and fantastic artworks. In his new exhibit at the Frist Center for the Visual Arts in Nashville (TN, USA), Nick Cave: Feat., several Soundsuits are on display. Each is intricately composed of interlaced second-hand objects: plastic buttons, sequins, synthetic hair, raffia, toys, and fabric woven together. The Soundsuits might remain in a fixed state as sculptures, or be worn and brought to life through movement. The wearable artwork is designed to make noise through movement and dance, becoming a body of artwork that is simultaneously a sculpture, costume, and musical instrument. Cave and others wear the suits, while musicians drum and photographers capture the interchange between his works. At first glance, Cave's Soundsuits are fanciful, but just beneath the surface, these collections of commonplace objects have a deeper meaning.

Hoarding disorder (HD) is a common, debilitating mental illness and public health burden. Understanding the factors that contribute to hoarding is critical for identifying treatment targets. As a relatively new diagnostic entity, this research remains in its initial stages. Intolerance of uncertainty (IU) is thought to be a vulnerability factor for generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD), and may also be relevant to HD. We investigated the possible association between IU and hoarding in two sets of analyses.First, we administered self-report measures of IU and hoarding symptoms to unscreened undergraduate students (N=456) and used regressions to probe their association controlling for relevant covariates. Second, in a clinical sample, we compared IU across groups of patients with HD (N=26), GAD (N=26), OCD (N=51), other anxiety disorders (N=91) and healthy controls (N=29).In the student sample, IU predicted hoarding symptoms above and beyond relevant covariates, including hoarding-related beliefs. In the clinical sample, HD patients evidenced greater IU relative to healthy individuals and the mixed anxiety group, and comparable levels of IU to the GAD and OCD groups.This study relied exclusively on self-report questionnaires and a cross-sectional design.IU is associated with hoarding behavior and, as we discuss, conceptual models might benefit from the study of IU as a potentially contributing factor. Directions for future research are discussed.

Prevalence and Correlates of Difficulty Discarding Results From a National Sample of the US Population 

Rodriguez, C. I., Simpson, H. B., Liu, S., Levinson, A., Blanco, C.


2013; 201 (9): 795-801



This study presents nationally representative data on the prevalence and the correlates of difficulty discarding, a behavior described in many psychiatric disorders, including a new diagnosis in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, called hoarding disorder. Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions, a national sample of the US population (N=43,093). Difficulty discarding worn-out/worthless items (assessed by a single item) and diagnoses of psychiatric disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule. The prevalence of difficulty discarding worn-out/worthless items in the general population was 20.6%. Difficulty discarding strongly correlated with axis I and axis II disorders, level of impairment, and use of mental health services. Difficulty discarding worn-out/worthless items is a common behavior that can be associated with various forms of psychopathology. When reported in a clinical setting, it may signal that careful assessment is needed to clarify diagnosis and inform treatment strategies.

Prevalence of Hoarding Disorder in Individuals at Potential Risk of Eviction in New York City A Pilot Study 

Rodriguez, C. I., Herman, D., Alcon, J., Chen, S., Tannen, A., Essock, S., Simpson, H. B.

This study estimated the prevalence of hoarding disorder (HD) in individuals seeking help from Eviction Intervention Services Housing Research Center (EIS), a not-for-profit community organization in New York City (NYC) that aids clients with housing problems including eviction. One hundred fifteen EIS clients were screened for HD. The prevalence of HD among those seeking help from EIS was 22% (clinician-rated) and 23% (self-rated), which is nearly 5 to 10 times greater than the rate of hoarding (2% to 5%) in the general population. Of individuals seeking help from EIS who met the criteria for HD (n = 25), 32% were currently in legal eviction proceedings (i.e., threatened with imminent eviction), 44% had a history of previous legal eviction proceedings, and 20% had been evicted from their home one or more times, yet only 48% were currently seeking mental health treatment. Almost a quarter of individuals seeking help for housing problems from a community eviction prevention organization met the criteria for HD; only about half of these individuals were receiving mental health treatment. Future studies are needed to determine whether HD treatment can reduce the risk of eviction and homelessness in NYC.
