Psychometric properties of the Persian version of the Fleishman Job Analysis Survey (FJAS)

Abstract

BACKGROUND: Job analysis is one of the most important and widely used processes to determine job duties, identify and reduce potential risks, and specify the skills and facilities required for each job at the highest level of occupational safety and health. OBJECTIVE: This study aimed to perform psychometric analyses of the Persian version of the Fleishman Job Analysis Survey (FJAS). METHODS: A cross-sectional study was conducted among 31 drivers. Participants were selected by random sampling. Ten occupational health and ergonomics experts confirmed the validity of the survey. First, we calculated the survey’s CVR and CVI. Then, we used ICC and Cronbach’s alpha coefficients to evaluate the survey’s reliability. Data analysis utilized SPSS 21. RESULTS: 78% of the participants were male and 22% were female. The mean age±SD of the participants was 39.1±11.82 years. The reliability and validity of the short version survey showed that the value of ICC and Cronbach’s alpha coefficient was 0.96, and CVR was 0.75. Moreover, the values of CVI for simplicity, clarity, and relevance were 0.87, 1, and 0.73, respectively. The long version’s ICC and CVR were 0.96 and 0.97, respectively. Simplicity, clarity, and relevance CVI scores were 0.9, 0.94, and 0.95. CONCLUSION: The results of this study showed that the Persian version of the Fleischman Job Analysis Survey has the necessary validity and reliability for job analysis, so it can be used for driving professional or research purposes. Moreover, this survey is an effective tool for obtaining accurate and complete knowledge of job tasks and requirements.
