Jenkins activity survey

The Jenkins Activity Survey is one of the most widely used methods of assessing Type A behavior.

The JAS is a psychometric survey of behavior and attitude designed to identify persons showing signs of Type A behavior. The test is multiple choice and self-administered.

It was published in 1979 by C. David Jenkins, Stephen Zyzanski, and Ray Rosenman. The terms Type A and Type B personality were originally described in the work of Rosenman and Friedman in the 1940's.
