Increasing Organ Donation via Anticipated Regret (INORDAR): Protocol for a Randomised Controlled Trial.
O'Carroll RE, Ferguson E, et al.BMC Public Health, 12(1): 169, 2012.
Aims
This study protocol of a randomised controlled trial aimed to explore whether a simple, theory-based anticipated regret manipulation would lead to a significant increase in posthumous organ donor registrations.
Interventions
The participants are randomly assigned to receive a letter and donor registration form versus a questionnaire measuring their emotions and non-cognitive affective attitudes towards organ donation versus emotions and affective attitudes questionnaire plus items assessing their cognitive attitudes towards organ donation, perceived control over registration and how they think significant others view this action (the theory of planned behaviour group) versus the same indices as the theory of planned behaviour group plus two additional anticipated regret items (the anticipated regret group)
Participants
14,520 members of the adult Scottish general public.
Outcomes
The primary outcome will be NHS Blood and Transplant verified registrations as an organ donor within 6 months of receiving intervention. The secondary outcome is intentions to become an organ donor in the future.
Follow-up
6 months of receiving postal intervention.
CET Conclusions
This is a protocol for a large randomised study directed at over 14.000 adults in Scotland in which the aim is to see whether “anticipated regret†for not registering as an organ donor increases organ donor registration on the NHS Blood and Transplant registry 6 months later. The protocol is based on 3 pilot studies which suggest that “anticipated regret†would lead to an increase of validated registration on the UK donor registry.
Quality notes
