On the day of surgery and every day after the surgery (until discharge), both youth and parents will report pain characteristics (pain intensity [NRS], pain-related fear [NRS], pain interference [PROMIS], pain unpleasantness [a Likert scale], pain catastrophizing [state]), state anxiety (NRS), overall affect (NRS), and sleep quality (NRS). Parents will also complete a measure of parent responses to child pain (ARCS). Information regarding analgesic and anesthetic agents administered on the day of surgery will be collected via medical chart review.
