Proceedings of Annual Spain Business Research Conference 26 - 27 May 2016, Novotel Barcelona City Hotel, Barcelona, Spain, ISBN: 978-1-925488-05-0 An Examination of the Effect of Mood Disorders on Compulsive Buying Behavior: A Meta-Analysis Abdullah J. Sultan* Recently, there has been a growing interest in studying compulsive buying tendencies among consumers. Much attention has been given to why consumers become engaged in compulsive activities. More specifically, most studies have focused on personal factors that cause shoppers to buy compulsively (e.g., cognitive and emotional factors); however, these studies have reported contradicting findings about the causes of compulsive buying behavior; whether it involves negative mood disorders or positive mood disorders. Based on evaluating the effect sizes of several studies using fixed and random effect models, the researcher concludes that negative mood disorder is associated with compulsive buying behavior.
