Work and psychiatric disorder in the Whitehall II Study

Area of Science:

• Occupational Health
• Psychiatry
• Sociology

Background:

• Rapidly evolving work practices and declining job security necessitate research into their mental health effects.
• The Whitehall II Study, a significant cohort study, has been instrumental in examining these workplace influences.

Purpose of the Study:

• To investigate the relationship between work characteristics and mental health outcomes in a large cohort of civil servants.
• To identify specific workplace factors that may protect against or contribute to psychiatric disorders and sickness absence.

Main Methods:

• Longitudinal analysis of data from 6895 men and 3413 women in the Whitehall II Study, recruited between 1985 and 1988.
• Utilized modified Karasek indices via self-report questionnaires to measure work characteristics.
• Assessed psychiatric disorder using the 30-item General Health Questionnaire (GHQ).

Main Results:

• High levels of work social support were associated with lower GHQ scores (indicating better mental health) at follow-up.
• High job demands predicted higher GHQ scores at follow-up, suggesting a negative impact on mental health.
• Both high work social support and high skill discretion demonstrated a protective effect against psychiatric sickness absence.

Conclusions:

• Work social support acts as a protective factor for mental health and reduces psychiatric sickness absence.
• Job demands represent a potential risk factor for adverse mental health outcomes and increased sickness absence.
• Findings have significant implications for workplace management, job design, and employee training to promote mental well-being.
