Organ donation registration is key to increasing donation, but registration rates in Canada are low, necessitating the development of new, registration-promoting interventions. Behaviour theories could help to better understand registration behaviour, inform fit-for-purpose interventions, and assist in building cumulative evidence, but it is unclear how they have been applied to organ donation registration. Study 1 reports a systematic review identifying behaviour theories that have been applied to registration, and a meta-analysis of the amount of variance in registration intention and behaviour explained by behaviour theories. Study 2 reports a qualitative meta-synthesis of organ donation registration barriers and enablers, mapped to a behavioural framework. The resulting comprehensive set of factors helps to identify priorities for future research, and provide insights towards developing novel interventions to bolster registration rates in Canada.enOrgan DonationOrgan Donation RegistrationBehaviour TheoriesTheoretical Domains FrameworkThesis
