In the context of deprived communities, a behaviourally-informed self-referral letter incorporating anticipated regret messaging is effective at promoting previous non-attenders to complete screening 2. In the context of deprived communities, incentivisation using a regret lottery with a behaviourally-informed self-referral letter incorporating anticipated regret messaging is effective at encouraging the uptake of screening We will analyse these separately for bowel and cervical cancer, for a total of four primary study hypotheses. We will also test the treatment arms against each other, which constitute 2 secondary hypotheses: 1. In the context of deprived communities, incentivisation using a regret lottery with a behaviourally-informed self-referral letter incorporating anticipated regret messaging is more effective at encouraging the uptake of cervical cancer screening than just a behaviourally-informed self-referral letter 2.
