Consistent with previous research, Type A behaviour was also found to significantly
predict perceived stress. The relationship was moderate and positive, indicating that
this personality trait appears to mediate the existing effects of environmental stressors.
The results are consistent with Ganster’s (1987) suggestion that if Type A and Type B
people were to face equal occupational demands, Type A would show more
pronounced physiological and emotional activity. Subsequently, these individuals would
be most at risk of experiencing high levels of perceived workplace stress.
