Abstract

Background and purpose: Assessing job satisfaction within any organization is essential due to its impact on productivity and overall effectiveness. This study aimed to evaluate the validity and reliability of the Persian version of Spector's Job Satisfaction Questionnaire among employees of emergency medical centers. Methods: This descriptive-analytical study was conducted among 270 employees of emergency medical centers in Ahvaz between February 2021 and June 2021. Data collection was performed using a census method and Spector's Job Satisfaction Questionnaire. Face validity, content validity, and translation accuracy of the questionnaire were reviewed by experts. Convergent and divergent validity and reliability were assessed using factor loadings, average variance extracted (AVE), reciprocal factor loadings, Cronbach's alpha, and composite reliability in SMART-PLS 3 software. Results: The face validity, content validity, and translation accuracy of the questionnaire were confirmed by experts to suit the Iranian context. All item factor loadings and the AVE index for all constructs exceeded 0.4. The AVE index for the entire questionnaire was 0.523. Examination of reciprocal factor loadings confirmed divergent validity. Cronbach's alpha and composite reliability indices for all constructs were above 0.7. The Cronbach's alpha coefficient and composite reliability for the entire questionnaire were 0.83 and 0.88, respectively. Conclusion: The validity and reliability of this questionnaire, as adjusted for the Iranian population, were confirmed to be high. Therefore, this questionnaire can be effectively used to evaluate job satisfaction among employees in various organizations, particularly in healthcare organizations and centers.
