Validation of an instrument to assess knowledge, attitudes, and practices on tuberculosis among health care workers in Colombia
Abstract
Introduction. Tuberculosis persists in the national epidemiologic scenery; 289 cases of tuberculosis in healthcare workers were notified in 2022; this disease in sanitary workers is related to low levels of knowledge, deficient self-care measures, and low health attention quality. This study's objective was to validate an instrument for the evaluation of knowledge, attitudes, and practices about tuberculosis in healthcare workers. Methodology. Methodology study. Five experts validated the content, the appearance validation with 32 healthcare workers (HW), and construct validation with 140 HW. The inclusion and exclusion criteria depend on the validation phase. Data was processed in SPSS. Results. The instrument comprises three dimensions: knowledge, attitudes, and practices, and 43 items. The content validation reached a global content validation index of 0.96. The appearance validation demonstrated the understandability of the items in 84%. The exploratory factorial analysis ratified the conformation of the three dimensions with a sampling adequacy measure of Kaiser-Meyer-Olkin (0.741). Finally, the instrument reached an Alpha of Cronbach global of 0.72. Discussion. In Colombia, no validated and reliable instruments that evaluated this topic were identified. Different investigations in the world have indicated the utility and effectiveness of this type of tool. Conclusions. The instrument "evaluated" in workers showed content, construct, and appearance validity to measure knowledge, attitudes, and practices about tuberculosis in healthcare workers.
