A validation study of the OSI on a blue‐collar sample

The Occupational Stress Indicator is a diagnostic research tool which assesses seven different aspects of the stress—strain relationship. On the outcome or strain side, it measures job satisfaction, mental health and physical health. On the stressor or independent variable side of the equation, it assesses sources of job stress, type A behaviour, locus of control and coping styles. It has been previously validated for white‐collar and professional groups and this article describes its validation for a blue‐collar sample.
