Compulsive buying disorder (
CBD), or
oniomania (from
Greek ὤνιος
ṓnios "for sale" and μανία
manía "insanity"), is characterized by an obsession with
shopping and buying behavior that causes adverse consequences. According to Kellett and Bolton (2009, p. 83), compulsive buying "is experienced as an irresistible–uncontrollable urge, resulting in excessive, expensive and time-consuming retail activity [that is] typically prompted by negative affectivity" and results in "gross social, personal and/or financial difficulties". Most people with CBD meet the criteria for an
axis II disorder. Compulsive shopping may be considered an impulse control
disorder, an obsessive-
compulsive disorder, a bipolar disorder, or even a clinical
addiction, depending on the clinical source.
