title: Channels and vehicles of communication: the asbestos awareness campaign.
abstract: In April 1978, the U.S. Department of Health, Education, and Welfare launched a multimedia campaign to inform doctors, workers, and others about the increased risks of asbestos exposure. Unlike most worker notification efforts, this one has no lists of workers or even of workplaces but faced the challenge of locating people who had worked in the shipbuilding industries more than 30 years earlier. Multiple mass media channels were used, but since most messages were distributed as public service announcements, gatekeepers were critical to the success of the campaign. Some campaign messages were aired, but mostly at hours other than prime time, and the coverage focused more on the controversial, fast-breaking events rather than on estimates of risk or on behaviors to reduce risk. The campaign was effective in increasing the number of people who believed they were at risk, but was less successful with older Americans than with manual laborers.
