The anxiety level of children aged 4 to 7 years was assessed by the visual analogue scale (VAS) for anxiety. It is a 10-cm horizontal line marked with the words ”not worried” (low score) at one end and ”very worried” (high score) at the other, with different facial expressions drawn along the line. This scale has been shown to be reliable and valid for measuring the subjective feelings of anxiety in children.The anxiety level of children aged 8 to 12 years was assessed by the short form of the Chinese version of the State Anxiety Scale for Children (CSAS-C).
