For evaluating anxiety in children the Modified Anxiety Scale (mYPAS) will be used. The mYPAS is frequently used to measure anxiety prior to induction and has demonstrated both inter and intra-rater reliability (using k statistics) ranging from 0.63 - 0.90 and acceptable reliability (p = 0.01, r = 0.79) The tool can be administered in less than one minute, is reliable in children ages 2-12 years, and uses five areas (activity, vocalization, expression, arousal, and interaction) to rate preoperative anxiety.
