[Job satisfaction. Use of the Job Satisfaction Scale (JSS)].

Job satisfaction is an important determinant of wellbeing and a moderator of stress at work. The Warr's Job Satisfaction Scale (JSS) is probably the most used questionnaire to assess job satisfaction. The aim of this paper is to evaluate the Italian version of the JSS. The questionnaire has been distributed to 632 health care workers. Results show that the Italian version of JSS has good reliability (Cronbach's alpha = 0.94). Principal component analysis revealed that a significant percentage of the variance (52%) was explained by a single factor which included all the 16 items. Varimax orthogonal rotation yielded the same two factors observed in the original questionnaire: intrinsic and extrinsic job satisfaction. The JSS may be an useful tool in the assessment of psychosocial risk at work.
