The influence of type A behaviour and locus of control upon job satisfaction and occupational health

Results from this study show that in a sample of 332 German managers a Type A personality and an External locus of control are associated with greater perceived levels of stress (particularly in terms of inter-personal relationships), lower job satisfaction and a poorer physical and mental health than that of managers with a type B personality and an Internal locus of control. The magnitude of main effect size is substantially larger than the interaction terms (Type A×Locus of Control). There is no evidence to support a significant effect of a Type A×Locus of Control interaction on either of the health outcome measures (physical and psychological health), but there is some evidence of an interaction with work satisfaction outcomes (job satisfaction and organizational satisfaction). Those with an External locus showed significantly lower levels of work satisfaction, especially when this characteristic was combined with a Type A personality. It appears that negative health consequences may outweigh the superficial attractiveness of the type A personality in a managerial position, particularly when this trait is coupled with a more external locus of control.
