Abstract

There is considerable conceptual debate about how hoarding disorder (HD) and buying-shopping disorder (BSD) can be best classified. In this article, we reason that these disorders may represent behavioral addictions by mapping evidence to the Components Model of Addiction and the Interaction of Person-Affect-Cognition-Execution (I-PACE) model for addictive behaviors. Our review identifies phenomenological, psychological, and neurobiological evidence to support both disorders as behavioral addictions. However, limitations of the extant literature prevent strong conclusions from being made about the conceptual status of HD and BSD as behavioral addictions. By applying addiction theory to HD and BSD, we generate testable predictions for future research and open potential new avenues for psychological treatment advances.
