Causes of Stress - Work - Johansson et al (1978)
Aim: To measure the psychological and physiological responses of stress in two catagories of employee.
Method: Quasi-experiment. IV: Employees with a high risk of Stress (high responsibility jobs) + Control group (cleaners and maintenence workers). DV: chemicals in urine that are related to stress and self-report of mood.
Sample: 24 workers at a sweedish sawmill, 14 high risk/10 control.
Procedure: Pps gave 5 daily urine samples and a baseline sample (from when at home). Self reports of mood were made on a likhert scale. Included consideration for caffine + nicotine consumption.
Findings: The high risk group had twice the adrenaline levels when compared to their baseline that increased throughout the day. The control group had a peak leavel of 1.5 times their baseline, which decreased throughout the day.
In the self-report, the high-risk group felt more rushed and irritated whereas the control group rated their wellbeing lower.
Elaboration: This shows that repetitive, machine-paced work (which is demanding in attention to detail) was contrubiting to the higher stress levels in the high-risk group. To circumvent this, Johansson suggested that people should avoid this type of work, or impliment a stress management program.
