Evidence of Validity of the Knowledge Assessment Instrument on Metabolic Syndrome

Abstract

Abstract: This study aimed to develop and validate an instrument to analyze adults’ knowledge about metabolic syndrome. The instrument was developed via documentary research, resulting in 40 statements with Likert-type responses, organized into three domains: (1) knowledge about obesity and related diseases; (2) knowledge about risk factors; and (3) knowledge about protective factors. Experts’ analysis of the construct and testing on 600 participants were used to validate the instrument. Exploratory factor analysis indicated that six assertions had very low factor loadings and were excluded, resulting in 34 assertions. The final version of the instrument presented satisfactory internal consistency indicators, guaranteeing the first evidence of the instrument accuracy in assessing adults’ knowledge about metabolic syndrome.
