Personality traits, early childhood influences, social insecurities, and financial pressure are some of the factors that can promote addictive consumption. This chapter examines how psychological dispositions—such as impulsivity, low self-esteem, or neurotic tendencies—increase the risk of developing a dependency on shopping. The influence of external factors such as media, advertising psychology, and social networks is also considered. In particular, the omnipresence of digital purchasing options and algorithmic consumption control is playing an increasingly significant role in the development and maintenance of compulsive buying behavior.
