THE VALIDITY OF THE OCCUPATIONAL STRESS INDICATOR

This paper investigates the validity of four subscales of the Occupational Stress Inventory (OSI). Data derived from a sample of British managers are used to generate a multitrait–multimethod matrix. The results obtained suggest that three of the four OSI sales (job satisfaction, mental health, type A behaviour) show acceptable validity. The fourth scale (locus of control) needs further development. Further analysis, using multiple regression procedures, was conducted to explore the validity of the theoretical ideas underlying the OSI. The results reveal that both sources of pressure at work and type A behaviour are linked to mental health and job satisfaction. © 1990 Taylor & Francis Group, LLC.
