The relation of communication to risk judgment and preventive behavior related to lead in tap water

More and more communities are becoming concerned about health risks posed by lead and other health hazards in their drinking water. Our study, applying the model of innovation diffusion to the adoption of preventive health behaviors, found that reliance on health professionals for information about lead in tap water was associated with residents perceiving risk from this hazard, their sense of efficacy in dealing with it, and their adoption of preventive behaviors. Mass media and pamphlets mailed directly to residents were relatively ineffective. Results suggest that interpersonal channels may be the best way to reach individuals who live in areas of highest risk from tap water lead.
