Development and Validation of the Job Satisfaction Brief Scale

Abstract

This research aimed to develop and validate an instrument to measure job satisfaction in general. A total of 1,491 employed people who worked at least 20 hours per week and were 21 years of age or older participated in the study. The Job Satisfaction Brief Scale was developed with a total of eight items. Several exploratory factor analyses and several confirmatory factor analyses were performed using structural equation modeling to examine the scale's internal structure. The final version of the scale was composed of four items for which Cronbach's alpha and McDonald's omega coefficients were examined and fluctuated between .77 to .78. The results of the factor analyses, especially the confirmatory one, support the one-dimensional internal structure. The new scale appears to be invariance among gender, age, job position, and type of organization. In this way, the results provide evidence of the validity and reliability of the instrument created to measure job satisfaction in general.
