ABSTRACT
Aims
Today, measuring the job satisfaction is of the challenges that have increasingly occupied managers' minds. Considering the lack of a standard tool for measuring job satisfaction among the health care workers, this study was planned and carried out with the main purpose of preparation and standardization of the Job Satisfaction Survey questionnaire.
Methods This cross-sectional analytical study was carried out in September 2010. 301 employees of the Najmiyeh e Subspecialty Hospital were selected by stratified sampling method and answered the Job Satisfaction Survey questionnaire. Concurrent validity and confirmatory and exploratory factor analysis were used in order to examine the construct validity and Cronbach's Alpha method was used to examine the reliability. SPSS 16 and AMOS 18 were used to analyze data, using analytical statistical methods including Chi-square test.
Results Samples consisted of 301 subjects including 239 (81.8%) women and 53 (18.2%) men. The explanatory Factor analysis showed 7 factors with 62% total variance and 0.82 Kaiser-Meyer-Olkin Index. The results were also confirmed with confirmatory factor analysis (relative Chi-square=1.18, RMSEA=0.04, GFI=0.93, AGFI=0.91). The reliability of the questionnaire was reported 0.86 using the Cronbach's Alpha method.
Conclusion Considering that the validity and reliability indexes of the questionnaire are reported in acceptable range, the new version of Job Satisfaction Survey questionnaire is a valid and reliable questionnaire for measuring job satisfaction among military health care workers.
