Technique Overview

Type A and Type B Personality

Type A and Type B Personality Definition

C. Jenkins, R. Rosenman, M. Friedman and their associates (Jenkins et al., 1967) proposed that there is a correlation between heart disease and patients' personalities. People with Type A personalities are at highest risk. Friedman & Rosenman (1974) defined the Type A behaviour pattern as "an action-emotion complex that can be observed in any person who is aggressively involved in a chronic, incessant struggle to achieve more and more in less and less time". By contrast, people with Type B personalities are at lower risk because they are more relaxed in their approach to work and life.
