• The STAI-Y assesses anxiety as a personality trait and as a specific emotional response to a situation. The first part, STAI-Y-1, consists of 20 sentences assessing the current emotional state of the subject. The second part, STAI-Y-2, consists of 20 sentences assessing the subject's usual emotional state.

• In the STAI-Y-1, the subject indicates the intensity of his feelings on a 4-point Likert scale ranging from "not at all" to "many". In the STAI-Y-2, the subject indicates on a 4-point Likert scale ranging from "almost never" to "almost always", a frequency at which he usually feels the symptoms listed.
• To obtain the score for the STAI-Y-1, the scores for the 20 items (1 to 20) are summed. To obtain the STAI-Y-2 score, the scores for the 20 items (21 to 40) are summed. Each score can therefore vary from 20 to 80.
