Self-reported job insecurity and health in the Whitehall II study: potential explanations of the relationship

This paper examines the potential of demographic, personal, material and behavioural characteristics, other psychosocial features of the work environment and job satisfaction to explain associations between self-reported job insecurity and health in a longitudinal study of British white-collar civil servants. Strong associations were found between self-reported job insecurity and both poor self-rated health and minor psychiatric morbidity. After adjustment for age, employment grade and health during a prior phase of secure employment, pessimism, heightened vigilance, primary deprivation, financial security, social support and job satisfaction explained 68% of the association between job insecurity and self-rated health in women, and 36% in men. With the addition of job control, these factors explained 60% of the association between job insecurity and minor psychiatric morbidity, and just over 80% of the association with depression in both sexes.
