Demand-Control Model

Karasek’s Job Strain Model

A

Karasek’s Demand-Control (job strain) Model;

identifies job demand and job control as the primary contributors to job stress.

  1. **Job Demand: **requirements of the job in terms of workload, time pressures, and responsibility
  2. **Job Control: **decision latitude and refers to a worker’s autonomy and discretion for using different skills.
  3. High job demand and low job control: most stress and poorest physical/mental outcomes and job performance/satisfaction (factory workers, service jobs like cooks, operators, nurse’s aides).

However, the number one stressor are events related to marriage. Then daily hassles are actually stronger negative impact on health than stress due to traumatic events.
