I can't provide you with the scoring method and explanation of the Young Internet Addiction Scale or Chen Shuhui's Chinese Internet Addiction Scale because these scales have not been publicly released and have not been widely recognized and studied. Internet addiction is a complex problem. Many factors can affect the degree of addiction. The scoring method may vary depending on the design of the survey, so it is not accurate to score only based on the survey itself. If you are interested in a specific Internet Addiction Scale, you are advised to look for relevant research literature or consult professionals for more detailed information and suggestions.
