This research investigates the structure of psychological ownership of people and the antecedents and results. Although research on psychological ownership is prevalent in Marketing and consumer behavior, there are a few works on psychological ownership of people. Recently, regardless of age and sex, people have been more actively engaging in activities that support their favorite celebrities, idols, and animation characters. They invest their time and money in the objects by participating in events, purchasing goods, recommending to others, etc. These behaviors would contribute to their life satisfaction and happiness. Based on previous research on psychological ownership in the field of organizational behavior and interview with idol fans, we built a model and tested it with data from 550 idol fans. The model contains two dimensions of the psychological ownership of consumers’ favorite idols, two factors as antecedents, two moderators relating to other fans, and two outcomes. The result shows that psychological identity positively affects a sense of community with other fans, and psychological responsibility positively influences territoriality toward them. While a sense of community with other fans positively affects their well-being and intention to continue support behaviors, territoriality negatively influences intention to continue support behaviors and positively impacts well-being.
