Content validity for the identification of occupational and ergonomic risks in the management of Endoscopic Retrograde Cholangiopancreatography

Introduction: The team of professionals involved in the management of endoscopic retrograde cholangiopancreatography experiences occupational and ergonomic risks, for which validation instruments are required to facilitate the identification of these risks, in order to prevent occupational diseases. Objective: To validate the instruments for identifying occupational and ergonomic risks in the management of endoscopic retrograde cholangiopancreatography, using statistical methods of competence coefficient, Aiken's V and calculation of confidence intervals. Methods: Content validity was assessed using expert criteria based on Aiken's V. The study was conducted from February to April 2025. The experts' competency coefficient was taken into account. Content validation was performed using Aiken's V and its confidence intervals. Results: The instrument was comprehensively validated, with a score of 0.98 for occupational hazards (98.21%), while the ergonomic hazards instrument validation yielded an overall score of 0.99 for 98.93%, which is considered good, above 75%. The confidence intervals confirm the study's validity. Conclusions: Content validation was performed, which favors reliable research results. Specialist suggestions were taken into account based on the clarity and comprehension of the occupational risk instrument.
