The concept of stress refers to those situations that require individual adaptation efforts that go beyond its normal capacity. If such situations occur very often, they determine nonspecifi c changes in the body. The efforts the body makes to overcome these changes may produce disorders in the adaptive mechanisms of the body. Tolerance to stress may refl ect different adaptive levels of individuals, and such differences are of particular interest to professional activities carried out in environments considered to be stressful. In this regard the development and implementation of a diagnostic tool to illustrate the confi guration of the tolerance level to stressful situations was a major objective for psychological practice.
