Background and objectives: Compulsive buying has been associated with addiction, depression, and obsessive-compulsive disorder, as well as hoarding. The present study investigated the relationship that compulsive buying (CB) has with 'addictive' (i.e., sensitivity to reward), obsessive-compulsive, and depressive phenomena, after controlling for hoarding, substance dependence, manic, and Borderline Personality Disorder symptoms. Methods: 87 participants from a community population completed the online questionnaires for the study, however 70 participants (M = 29.19, SD = 10.45; 70% were female) were used in the analyses because of exclusion criteria. Results: As expected, CB measures correlated with hoarding, depression, sensitivity to reward, and, but less so, obsessive-compulsive measures. Sensitivity to reward was the most important predictor of CB severity, compared to obsessive-compulsive and depression symptoms. Hoarding was also an important predictor of CB severity. Limitations: Small sample size meant gender comparisons could not be made, and the use of a novel, communicated questionnaire meant that interpretation should be considered conservatively. Conclusions: Overall, findings suggest that CB may be most closely related to the phenomena associated with addiction (an increased sensitivity to reward), rather than obsessive-compulsive or depression symptoms. Hoarding and reward sensitivity perhaps might separate compulsive buying from ordinary and recreational shopping. (C) 2014 Elsevier Inc. All rights reserved.
