An Overview of Jenkins Activity Survey Data in South Africa
Jenkins Activity Survey (JAS) data on samples of executives are reviewed first, followed by data on non-executive samples. A strong possibility exists of an unusually high incidence of the Type A behaviour pattern, as measured by the JAS Type A scale, among white managers in business and industries characterized by a strong marketing orientation and in occupations characterized by fast, personalized feedback on performance. Afrikaans speakers tended to obtain higher mean Type A scores than English speakers, in some cases significantly so. Patterns of scores on the Factor S, J and H scales suggest that the high Type A scores do not necessarily imply a high risk for coronary heart disease. However, the possibility of other ill-health as a consequence should be considered.
