employed status are significantly correlated.
Comment
This is interesting work which focused on social relationship and profiles of
instrumental, emotional, and informational support. However, some revisions are
needed to make this work worthy of publication.
#1, Major
In generally, high education background and high employed status are correlated
high income. Therefore, such a well-endowed group can live with good mental
health. However, this theory may be common belief. And we need to focus on
some people who has not good mental health even if they have high income
(good social relation). Please describe about how to detect and rescue the
minority. Also please describe how to rescue the people the patients who have
not good social relationship.
#2, Major
Are there any affect for the outcome of present study by cancer treatment or the
fact of cancer?? As mentioned above, outcome of present study may be same as
general population. Please describe about the differences between cancer patient
and general population.
