Can psychological ownership help to mobilize people to get vaccines?

Vaccines have been crucial for dealing with infectious diseases. However, overcoming vaccine hesitancy remains challenging. In their article, Hengchen Dai (Anderson School of Management, University of California) and colleagues examine whether a communication strategy using reminders impact vaccine intentions. They report data from two sequential large-scale randomized controlled trials that investigate whether nudging people to get vaccinated can improve the uptake of vaccines. The authors randomized whether participants received text-message-based reminders or not and assessed whether they subsequently scheduled an appointment for the COVID-19 vaccine and eventually obtained the vaccine. In the first reminder the authors varied whether the reminder was designed to induce feelings of psychological ownership over the vaccine. Reminders indicated that the vaccine had ‘just been made available for you’ and encouraged participants to ‘claim your dose’. The results reveal that text-based reminders designed to overcome barriers can effectively encourage vaccinations. The effects are heightened when the reminders leverage psychological ownership, making people feel that a dose of the vaccine belongs to them. The research of Hengchen Dai and colleagues thus provide valuable insights into how vaccine uptake can be maximized and highlight the value of inducing feelings of ownership.
