Litter in a University Cafeteria: Demographic Data and the Use of Prompts as an Intervention Strategy

Investigated the effectiveness of posted feedback as a litter control strategy in a university cafeteria in the absence of written prompts. Patronage and litter rates were monitored daily throughout a school term. Posted feedback was effective in reducing litter rates relative to baseline. Reductions in litter rates were maintained following intervention and continued to be evident 2 wks after the completion of the study. Posted feedback was thus a simple and effective method of litter control.
