Abstract
A twin study was conducted to determine the relative contribution of genetic and environmental factors to the development of Pattern A behavior. Thirty five sets of college aged MZ twins and 21 sets of DZ twins completed the Jenkins Activity Survey for Health Prediction. This self administering questionnaire yields scales measuring Pattern A behavior and its related traits of Speed and Impatience, Job Involvement, and Hard driving Competitiveness. Results sowed a modest genetic component for the Hard driving Competitive aspect of Pattern A. Data were also presented regarding resemblances between the twins and their parents on Pattern A.
