Samenvatting
After a brief review of previous studies of the effect of mass media on safety belt use, the two-part investigations carried out, are described. First, a survey was conducted of actually observed safety belt users and non users to determine the factors which distinguished the two groups. Second, television messages were shown on one cable of a dual cable television system designed for marketing studies. Results show no significant difference between drivers from households on the experimental cable or on the control cable.
