A Preliminary Investigation of the Measurement of Object Interconnectedness in Hoarding Disorder
A defining feature of hoarding disorder (HD) is excessive attachment to possessions. Several existing self-report measures assess emotional attachment to items but do not explicitly assess the level of interconnectedness between the individual and their items. The current study investigated a new self-report measure of object attachment based on a measure of interconnectedness among individuals. The visual nature of this measure may be especially useful in HD patients since hoarding is often characterized by low insight. Participants completed the Relationship between Self and Items (RSI) measure and measures of hoarding severity, clutter, anxiety, and depression. HD participants reported significantly higher scores on the RSI than did community controls. The RSI was positively associated with hoarding symptoms, but was not significantly correlated with symptoms of anxiety or depression. Results also suggested that the RSI is sensitive to change from pre to post-treatment. This brief, one-item measure may be useful as a screen for HD and to provide further clinical data on level of interconnectedness to possessions.
