Validation of an instrument for measuring public health management indicators

Introduction: this study focuses on the need to validate and reliably measure management indicators in the field of public health in Paraguay using psychometric techniques. Objective: the main objective of this study was to develop a valid and reliable instrument to measure public health management indicators in Paraguay considering its psychometric properties. Methodology: this study followed a quantitative approach using a descriptive and propositional observational design. A pilot test was conducted using Likert scales to capture different aspects of public health management indicators. Exploratory and confirmatory factor analyses were performed to validate the construct, and the JASP was used for statistical analysis. The sample included adults in Paraguay who were connected to the public health system in the previous year. Results: the results showed that Aiken's V for all items was higher than 0.7, indicating content validity. The fit indices of the confirmatory factor analysis, such as RMSEA=0.064 and CFI=0.971, demonstrated good construct validity. In addition, the alpha and omega values were higher than 0.9, which guarantees the high reliability of the instrument. Conclusion: these results indicate that the developed instrument is valid and reliable for measuring public health management indicators in Paraguay.
