RESUMO
This study aims to develop and validate a job satisfaction scale for human resources for health (HRH) who are employed by the Ministry of Health. The scale was developed through a comprehensive literature review, and its validity and reliability were assessed using several psychometric properties, including expert evaluation, a pilot survey, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). A large sample psychometric evaluation was made by all kinds of HRH staff (n = 2122), and the final version of the job satisfaction scale included 25 items. The EFA revealed seven factors with modest internal consistency ranging from 0.68 to 0.85. The goodness of fit of the model was found to be satisfactory, with root mean square error approximation (RMSEA) = 0.05, chi-square/df = 6.4, and both Tucker-Lewis Index (TLI) = 0.92 and CFI = 0.93 being higher than 0.9. The standardized root mean square residual had a value of 0.035. This instrument proved to be a reliable and valid tool for measuring job satisfaction in health institutions.
