  1. aAIA = adolescent internet addiction.
  2. bPrevalence of Internet use: the ratio of the number of adolescents using internet to the number of the whole adolescent sample in that group. Chi-square was used to compare the prevalences of internet-use among different levels of the same family background variable.
  3. cTotal scores: total scores of DRM-52 Scale. ANOVA was used to analyze the differences of total scores of DRM-52 Scale among different levels of the same family background variable.
  4. dPrevalence of AIA: the ratio of the number of internet-addicted adolescents to the number of the whole adolescent sample in that group. Chi-square was used to compare the prevalences of AIA among different levels of the same family background variable.
