Following an awareness campaign targeting the use of safety belts at a large pharmaceutical company, the present research examined the effects of a variable-rate cash-incentive strategy designed to further boost the level of plant-wide safety belt use. The observed percentage of belt use showed a sig- nificant increase during the incentive phase and a subsequent decline during short-term follow-up, although levels during follow-up were significantly higher than during baseline. Belt wearing was found to be essentially un- changed 6 months later during long-term follow-up.survival and growth for entrepreneurs.
