Maximising response is an important issue in epidemiological research. Reciprocation and commitment/consistency are psychological persuasion principles that have been used in many contexts to increase compliance with requests. We attempted to apply both these principles to increase compliance with a survey request by sending a fridge magnet reminder. The aim of this study was to determine whether the magnet improved response.
