Personality characteristics of the accident involved employee

The research relating personality traits to industrial and traffic accidents is reviewed. The research from the past 15 years is integrated with the multitude of studies preceding this period. All of the research is interpreted in terms of the differential accident liability concept, rather than the discredited accident proneness theory. The need to control for the confounding effects of age, experience, sex, and accident risk is discussed. It is concluded that the personality traits of extroversion, locus of control, impulsivity, aggression, social maladjustment, and some aspects of neurosis are related to the occurrence of accidents. Finally, the need to develop causal models of the personality-accident process and to identify causal influences through time series designs is proposed.
