Resumen

Objective: To obtain the frequency of digital visual fatigue (DVF) using two questionnaires among students of a private university in Lima, Peru; to estimate the degree of agreement between both methods. Methods: A cross-sectional study was conducted in a sample of 345 participants over 18 years old, students of a university in Lima, Peru and who completed the data collection instrument. The two methods used for the measurement of DVF were the Hayes questionnaire, which defnes a positive case for DVF with a score equal to or greater than 20; and the Seguí CVS-Q questionnaire, which defnes a positive case for DVF with a score greater than 6. The Cohen's kappa coefficient with its 95% confdence interval was estimated to measure the overall agreement and by strata. Results: The Hayes questionnaire identifed 167 (48.4%) participants with a presumptive diagnosis of DVF, the Seguí questionnaire identifed 247 (71.6%) students. In the concordance analysis, Cohen's Kappa coefficient was 0.45 (95%CI; 0.37 - 0.53) (p < 0.01) in the overall analysis, considered moderate. Conclusion: The degree of concordance between both methods was moderate, the Seguí instrument identifed a higher proportion of university students with DVF.
