The following questions deal with the workload that you experience in your job. Please put an ‘X’ on each of the following six scales at the point that matches your overall experience of workload.

	Low	High
1. Mental demand. How much mental activity is required to perform your job (thinking, deciding, calculating, remembering, looking, searching, etc…)?
2. Physical demand. How much physical activity is required to perform your job (e.g., pushing, pulling, turning, controlling, activating, etc.)?
3. Temporal demand. How much time pressure do you feel due to the rate or pace at which the tasks or task elements occurred?
4. Effort. How hard do you have to work (mentally and physically) to accomplish your level of performance?
5. Performance. How satisfied are you with your performance at your job?
6. Frustration level. How insecure, discouraged, irritated, stressed and annoyed versus secure, gratified, content, relaxed and complacent do you feel about your job?
