Abstract
Objetive: Validate an instrument for physicians from the first level of health care that measures the level of knowledge about dengue warning signs.
Materials and Methods: An instrument validation analytical study, for which an instrument created by the researchers was designed. This instrument was evaluated by the Delphi method by 7 experts in epidemiology, infectology and public health from more than 5 years of experience in the management of patients with dengue, the initial construct consisted of 22 questions that were evaluated in three rounds, with four being modified and 6 questions eliminated, leaving the final version of 16 questions, an average of intelligibility and relevance was obtained. Reliability was evaluated in 40 physicians working in the first level of health care in the Lambayeque region, using the Crombach Alpha Kuder Richarson-20 to assess reliability, in addition the Kaiser-Meyer-Olkin coefficient (KMO> 0.5) and Bartlett's sphericity test (<0.05), using the SPSS version 22 program.
Results: A 16-item instrument was developed with an average intelligibility and relevance of 5 / 4.5 respectively. A global Crombach's alpha of 0.81 was obtained with a correlation variation per item from 0.07 to 0.69 and a Kuder Richarson of 0.81. The Kaiser-Meyer-Oklin (KMO) with a value of 0.66 and the Bartlett's Sphericity test less than 0.05.
Conclusions: An instrument that proved to be valid and reliable was designed to evaluate the knowledge of physicians of the first level of health care on the warning signs of dengue.
