Purpose: In the present study, we investigated whether the relationship between identity confusion and compulsive buying (offline/online) and hoarding is mediated by materialistic value endorsement and depression. Procedures: The community sample consisted of 254 Flemish adults who completed self-report questionnaires to assess identity confusion (Erikson Psychosocial Stage Inventory), compulsive buying tendencies (Compulsive Buying Scale/short-Internet Addiction Scale, adapted for shopping), hoarding tendencies (Saving-Inventory Revised), materialistic value endorsement (Materialistic Value Scale), and depression (Patient Health Questionnaire-9). Findings: We found significant positive associations between identity confusion, compulsive buying, and hoarding. The association between identity confusion and compulsive buying was fully mediated by materialistic value endorsement; whereas depression mediated the association between identity confusion and hoarding. Conclusions: The results suggest that the collection or buying of material goods can be considered as identity substitutes. (C) 2016 Elsevier Inc. All rights reserved.
