Background: Prudent research management requires the archiving of original source documents (SD), e.g., questionnaires, in case they are needed during, or after, a project for research or audit purposes. Due to space and other resource constraints, paper archives are being replaced by electronic storage archiving such as CD-ROM/DVD of scanned documents, on the assumption that the scanned image is identical to and contains all the information in the original SD.
Methods: We examined to what extent the scanned SD image stored on CD-ROM is valid for research purposes, by analyzing SD information contained on a CD-ROM archive of alcohol or other drug use and risky sex behavior data, collected between 1999 and 2002 in Miami-Dade, for completeness, legibility, and record locator accuracy.
Results: Of 454 commercially scanned initial intake subject records, at least 11.2% were incomplete, having the following errors: Missing or non-existent subject records (3.3%); Missing or mislabeled record locators; Missing pages within a record; Incomplete pages within a record ; Incomplete words within a record or research project code book (e.g., unidentifiable variable names); Pages/data elements scanned out of order.
Conclusion: Because alcohol or other drug use and risky sex behaviors are socially stigmatized or illegal, there are known difficulties in ascertainment and obtaining accurate respondent information; errors may be compounded further due to current record archiving technology.
