One of the scales evaluates state anxiety, characterized by subjective feelings of tension and apprehension, followed by autonomic nervous system responses at a given moment. Trait anxiety, assessed by the other scale, refers to a relatively stable tendency to perceive situations at threatening and react anxiously to them. The scores are divided into low, moderate, high and very high and are determined by the sum of 20 symptoms from a 5-point Likert-type scale.The range of scores is 20-80, the higher the score indicating greater anxiety for both the Trait and State Anxiety.
