| Abstract: | In the past ten years or so, attempts have been made to understand better the essential nature of Type A. Yet, important questions remain as to exactly what the behaviour pattern is, how we can measure it reliably, and how we can help persons change their Type A behaviour as a means, it is hoped, of reducing their risk of CHD. Lack of a theoretically-based conceptual model of Type A is cited as one of the important reasons why serious conceptual; assessment, and treatment problems persist in this field. A recently developed model of Type A based on cognitive social learning theory is presented. The model focuses on the interplay among cognitive, behavioural, physiological, and environmental factors in the acquisition and maintenance of Type A behaviour. Personal beliefs and the fears they spawn are seen as forming the core of the behaviour pattern. Several of these beliefs are discussed. For instance, believing that one's personal worth is tied to one's tangible accomplishments is shown to explain the presence of many behaviours traditionally considered to constitute Type A. Environmental factors associated with the workplace are also discussed in terms of how they contribute to the persistence of Type A behaviour throughout adult life. |
