This chapter considers the challenges that arise in accurately identifying the occurrence of disease, or more broadly, health outcomes. It considers the methods for detecting such errors and quantifying their impact on measures of association. Some amount of error in assessment is inevitable, with the extent of such error depending on the nature of the health outcome of interest, the ability to apply definitive (sometimes invasive) tests to all participants, and human and instrument error associated with gathering and interpreting the information needed to assess the outcome.

Keywords: epidemiological research; epidemiological studies; disease misclassification; exposure; integrated assessment; bias
