A warning compliance study, conducted on 170 university undergraduates, compared the rates of safety compliance with three forms of instruction and warning information (written, oral, and combination) and two forms of message formality (formal and informal). Under the guise of a cover story, subjects were presented with the material and told to read (or listen to) it before performing routine product tasks. Dependent measures were compliance with the warning and time spent with the material. Compliance with the warning information was significantly affected by product. Predictor information included gender, previous product use, and product hazard rating. Hazard rating of the product was reliably correlated with product and with safety compliance. Time spent with the instruction and warning information was reliably correlated with gender, but was not significantly correlated with safety compliance. The results are discussed with regard to the warning situation and in comparison to previous risk perception research.
