This chapter covers the use of medical records and other types of records, diaries, and proxy respondents in exposure measurement in epidemiology. For each of these methods, topics covered include the advantages and limitations of the method, sources of error and quality control procedures specific to the method. For records, careful design of the record abstraction form, precise definition of terms, and abstractor training should reduce error. The accuracy of diary information can be enhanced by use of multiple diary days spread over a sufficient time period, and by careful training of subjects and coders. There is substantial error and item non-response in data provided by proxy respondents. For studies which use proxy respondents, close relations of the index subjects should be selected as the proxies, and proxies should be used for some (or all) controls as well.

Keywords:   medical records, record abstraction form, diaries, food records, number of diary days, coding, reactivity, proxy respondents, surrogate respondents
