| Abstract |
The validity and accuracy of work histories are discussed in the context of potential exposure misclassification and its impact on risk assessments. Misclassification that occurs independently of disease classification will usually lead to underestimates of the strength of the exposure-disease relationship, whereas misclassification that is not independent can produce over- or underestimates of risk. In the range of sample sizes that epidemiologists typically encounter, the chance probability is low that misclassification is independent of disease classification. Some suggestions for ways to enhance the validity of work history data for future epidemiology studies are offered. These include focusing on longer-term workers within an occupation or industry and soliciting work history data from multiple sources to offset the disadvantages of any single source. Finally, investigators are urged to validate their exposure estimates and adjust risk estimates for misclassification bias. |
