Cross-Cultural Adaptation, Psychometric Properties and Measurement Invariance of the Italian Version of the Job Satisfaction Scale

The JSS is based on the theoretical position that job satisfaction represented an affective or attitudinal reaction to a job, and today is one of the most popular instruments used in I-O psychology. This paper discusses the contribution to the validation of an Italian adaptation of the Job Satisfaction Survey. Five hundred and twenty-seven participants (258 men, 269 women) were enrolled to participate in this study, aged between 19 and 65 (M_age = 36.0, SD = 11.7). The sample mostly worked in public administration, in health care, and in the educational sector. A self-report questionnaire is used to investigate the psychometric properties of this scale, also measuring other variables. A back-translation procedure is used. The results pinpointed the goodness of the scale and the normality distribution. Confirmative factor analyses and multigroup confirmative factor analyses were performed to verify the factorial structure of the scale. The results confirmed the same factorial structure of the original version, suggesting a nine higher-order factor structure. The results from the multigroup confirmatory factor analysis showed that this factor solution was invariant across gender (men vs. women) and found evidence for metric invariance, uniqueness invariance, and scalar and structural invariance. The findings confirmed the applicability in the Italian context
