Design outcomes

Secondary

MeasureTime frame
1. Intentions to become an organ donor in the future 2. If the anticipated regret intervention is successful the trialists will test whether the increase in registration is due to people having greater intentions to register as an organ donor and less negative emotions and attitudes towards donation 3. These variables will be measured in questionnaires using the indices described above

Primary

MeasureTime frame
1. Verified number of NHS Blood and Transplant organ donor registrations in each of the four study arms, 6 months after receiving the postal questionnaire 2. NHS Blood and Transplant will search the Organ Donor Database to see whether participants have registered as organ donors and, if applicable, when they registered
