The scoring criteria are as follows: "1" indicates none or very little time; "2" indicates some of the time; "3" indicates a good part of the time; "4" indicates most or all of the time.According to normative results, in China, the standard deviation cutoff for SAS is 53 points. The divisions are as follows:53 to 62 points: Mild anxiety，63 to 72 points: Moderate anxiety，Above 72 points: Severe anxiety.

The Self-Rating Depression Scale (SDS) was developed by W.K. Zung in 1965. This scale comprises 20 items reflecting subjective feelings of depression, with each item rated on a four-point scale based on the frequency of symptoms. For positively scored items, the ratings are 1, 2, 3, 4 respectively, while for negatively scored items, they are 4, 3, 2, 1. The normal upper limit for the total raw score of SDS is 41 points, with lower scores indicating better states. The standard score is obtained by multiplying the total raw score by 1.25 and taking the integer part. The standard deviation cutoff for SDS is 53 points. The divisions are as follows:53 to 62points:Mild depression，63 to 72 points: Moderate depression，Above 73 points: Severe depression.
