Abstract
Background: Questionnaire is one of the efficient tool to gather health-related data. Measuring and reporting validity and reliability of research tool are important.

Objectives: To establish the test-retest reliability of a questionnaire to assess ergonomic knowledge of Computer professionals.

Materials and Methods: An Ergonomic knowledge questionnaire was administered twice at 2 weeks interval to the same set of Computer professionals (N = 20). Pearson correlation coefficients at 95% confidence interval were computed.

Results: The test-retest reliability of the sections of the Knowledge questionnaire seems to be fair to high. The results also showed that Correlation values (r) were highly significant for all the sections of the questionnaire (P<0.001).

Conclusion: The questionnaire demonstrated adequate test-retest reliability to assess the Ergonomic knowledge of Computer Professionals.

Key words: Computer Professionals, Ergonomic Knowledge, Questionnaire, Reliability
