First, On their parents' education of variables associated with adolescents’ parents, there is no significant difference in all three scales - academic stress, depression and family health. Depending on whether adolescents live their parents together or not, in case of living with their mother, there is a significant difference in all three scales. In other words, adolescents living with their mother get lower scores on academic stress and depression, and get higher scores on family health. Concerning conversation-time with adolescents’ parents, all three scales show significant differences. That is to say, having a lot of conversation-time among family members doesn't automatically prove that it is good for adolescents. but overall, it has positive influences on all three scales. Second, the correlation analysis on academic stress, depression and family health shows that the higher the academic stress, the greater the depression; meanwhile, the healthier the family functioning, the lower the academic stress and depression.
