[Reliability of the Karasek scale in the assessment of perceived occupational stress and gender-related differences in scores. The SEMM study].
In recent years more attention has been paid to the relationship between work organization and job stress and chronic-degenerative diseases. Aims of this report are the assessment of the reliability and internal consistency of the Karasek's Job Content Questionnaire-JCQ and to assess age-specific distributions of core JCQ scores between the gender groups. The study has been carried out in a large group of employees (n. 7871 subjects, 5270 women and 2601 men) of the Municipality of Milano in the years between 1992 and 1996. Decision Latitude (DL), Psychological Job Demand (PJD) and Social Support at Work (SSW) scores were calculated. Reliability of the JCQ was satisfactory, with Cronback's alpha suitable values for DL and SSW and acceptable for PJD. From the distribution of gender- and age-specific mean scores, women show reduced probabilities of developing a favorable career and of perceiving satisfactorily the support from colleagues and supervisors than men when they get older. This results suggest that the Karasek's JCQ is an effective toll to describe perceived job stress conditions in this Italian work setting.
