Anxiety Score From the Modified Yale Preoperative Anxiety Scale

The modified Yale preoperative scale consists of 5 categories (activity, vocalizations, emotional expressivity, state of apparent arousal, and use of parents). Four of the five categories are scored between 1-4 points and one of the categories is scored from 1-6 points. The scores are divided by their number of possible points in their respective category and multiplied by 20 to get the final anxiety score which ranges from 20 to 100. Low numbers represent low anxiety and higher numbers represent high anxiety.
