Abstract
In an experimental study designed to investigate a decision- making model of seat- belt use, 227 employees of an agrochemical company participated in a health information program in which they watched either a videotape on seat belts or a control videotape and completed questionnaires immediately afterward and at 3 months and 1 year after exposure. The findings are discussed in terms of the role of subjective probabilities and habitual factors in seat- belt use.
