Objective To explore middle school students' life values and its effective factors in Yushu after the earthquake. Method The Life Values Scale and Adolescent Resilience Scale were used to investigate 300 middle school students in Yushu after earthquake. Results 1) Yushu middle school students who were only-child or not made significant differences in life value score (t=-2.553,P<0.05);2)The students in middle or junior school had significant differences in the social value,individual value,spiritual value,transcendental value and life value score(t=-3.195,P<0.05);3)Different family disaster degree of Yushu middle school students' had significant differences in life value scores (F=4.490,P<0.05);4) Yushu middle school students' life values scores and all its factors were positively correlated with target focused,positive cognitive,family support factors of resilience(P<0.05),the survival value was negatively correlated with emotional control (P<0.05);5) The target focused,positive cognitive and family support factors of resilience could predict life value (P<0.05). Conclusions The extent damage,only-child or not can make great influence on participant's life value.The higher the resilience is,the higher life value is.Resilience can positively predict life values.
