Abstract

We read with great interest the article recently published in The IJOEM by Rai, et al, on the reliability and validity of a questionnaire for assessing occupational exposures to hazardous chemicals among health care workers in Bhutan. We really appreciate the efforts put by the authors for undertaking such a thought-provoking study that have pivotal role in occupational health of the developing countries. This paper well explained the importance of collecting valid and reliable occupational history data in estimating occupational exposures and work-related health effects. However, there are certain issues that need to be addressed. The title of the study creates a curiosity to learn about the reliability and validity of an adapted questionnaire. As the study process, the method tapers down the study into two stages (1) adaptation of the National Institute for Occupational Safety and Health (NIOSH) questionnaire, and (2) test-retest reliability assessment Comments on “Reliability and Validity of an Adapted Questionnaire Assessing Occupational Exposures to Hazardous Chemicals among Health Care Workers in Bhutan”
