The aim of the study was to assess subjective stress to 92 nurses by administering the Rapid Stress Assessment (RSA) Scale, a self-rated tool. The self-administered test, easily understandable, which is quickly drawn up and which allows a quick scooring, appears to be suitable to select subjects deserving a thorough specialistic investigation. The test itself becomes therefore a useful professional means for the occupational health physician, who has to evaluate the workers' psychic and physical attitude.
