Keywords: Job satisfaction, measurement, exploratory and confirmatory factor analysis, validity
Job satisfaction is a concept highly examined in the international literature. However, in Italy there are little studies that have analyzed both the theoretical status and the measurement of job satisfaction. Therefore this contribution has two aims: on one hand to describe the «state of the art» on job-satisfaction measurement, on the other hand, to examine the validity of three particular measures of job-satisfaction on an Italian sample. With regard to this second aim the "Minnesota Satisfaction Questionnaire" (MSQ), the "Job Descriptive Index" (JDI) and the "Satisfaction with Job General" (SJ) scales have been administered to a sample of 344 subjects. Exploratory factor analyses and reliability analyses have shown that these three scales present adequate psychometric properties.
