Warning research: an integrative perspective.

We developed an integrative perspective on the empirical evidence supporting the influence of particular variables on the warning process based on a broad review of the warning literature. The warning process is described in terms of the following four components: notice, encode, comprehend, and comply. Relevant variables are classified as person variables (characteristics of the individual interacting with the warning) and warning variables (characteristics of the warning itself or the context in which the warning appears). This integrative perspective yields general principles about the variables that influence the warning process and serves as a resource for warning developers and as a guide to facilitate effective analysis of warnings. We also identify aspects of the warning process that are not well understood, directions for effective methods of intervention, and a research agenda for future efforts. Actual or potential applications of this research include improving the design of warnings.

Mitral valve prolapse. Disease or illness?

Mitral valve prolapse (MVP) is a common condition that is believed to be responsible for numerous symptoms and potentially serious complications. To determine whether symptoms and functional impairment are related to MVP itself, we studied 274 outpatients referred to an echocardiography laboratory for suspicion of MVP. The age, sex, and symptoms at the time of echocardiography were similar among patients with and without evidence of MVP. After 14 to 36 months, 158 patients were interviewed. There was a high rate of dysfunction, but echocardiographic evidence of MVP was not associated with disability, health care utilization, or reported symptoms. The results of this study suggest that symptoms and dysfunction are not related to the presence of MVP by echocardiography. The functional impairment that is seen in patients suspected of MVP may be caused by other factors.
