interpersonal initiative（r=0.32）

interpersonal flexibility（r=0.30）

and interpersonal openness（r=0.20）all had a relation of direct proportion to positive mood state（P<0.05）

while interpersonal responsibility（r=-0.18）and interpersonal openness（r=-0.17）both had a relation of inverse proportion to negative mood state（P<0.05）.Feedbacks obtained gradually showed that interpersonal initiative and interpersonal flexibility markedly predicted positive mood state（P<0.01）

while interpersonal responsibility markedly and inversely predicted negative mood state（P< 0.05）.Conclusion Interpersonal independence is able to preserve emotional health through increasing positive mood and reducing negative mood.
