Differences Between Individuals Diagnosed with OCD-Hoarding Compared to OCD-Nonhoarding

Denise Moquin (2010)

The purpose of this study was to examine the differences in clinical symptom severity and treatment receptivity between individuals with Obsessive-Compulsive Disorder (OCD) with hoarding behaviors (OCD-H) and with OCD without hoarding behaviors (OCD-NH). Fifty-one participants diagnosed with OCD participated in this study. The Yale-Brown Obsessive Compulsive Scale was initially administered to determine OCD symptom severity. Only participants with a score of 16 or higher (moderate OCD symptom severity) were eligible to participate. The Savings Inventory-Revised was then administered to each participant who reported hoarding behaviors as their primary compulsive behavior. Six additional measures were then administered to each participant to examine group differences: (a) Beck Depression Inventory-II, (b) Beck Anxiety Inventory, (c) Beck Hopelessness Scale, (d) Overvalued Ideas Scale, (e) University of Rhode Island Change Assessment (modified for this study), (f) and Responsibility Attitude Scale. Results of this study revealed a statistically significant difference in both depression and hopelessness severity, with OCD-H participants endorsing higher levels of depression and hopelessness than OCD-NH participants. In addition, results of this study revealed a statistically significantdifference in treatment receptivity between OCD-H and OCD-NH. OCD-H participants endorsed lower levels of motivation for change, lower levels of insight, and higher levels of responsibility surrounding the interpretation of intrusive thoughts than OCD-NH.
