Background:
We aimed to assess the reliability of a self-reported questionnaire on occupational radiation practices among radiologic technologists.
Methods:
We enrolled 941 participants who had repeatedly completed the questionnaire from the 2012-2013 radiologic technologists' health study in South Korea. We used percentage agreement, kappa statistics, and intraclass correlation coefficient (ICC) to assess the reliability of responses on work practices.
Results:
Overall agreement for ever-never diagnostic radiation procedures was high (87.5-97.5%), and κ values indicated substantial agreement (0.66-0.86) in all procedures except cephalometric and intraoral radiography. For the information of year of work start and working duration, high agreement was obtained (ICC: 0.99 and 0.98, respectively). However, use of a worn dosimeter and of personal protective equipment showed only moderate to substantial agreement.
Conclusions:
Self-reported information on working practices regarding radiation exposure in radiologic technologists was reliable enough for epidemiologic studies. Am. J. Ind. Med. 60:377-385, 2017. © 2017 Wiley Periodicals, Inc.
