Objective To evaluate the reliability and validity of adolescent students for time horizon questionnaire（THQ）

and to understand the characteristics of adolescent students’temporal self-value.Methods The sample consisted of 1985 adolescents in Yunnan completed through time horizon questionnaire.Results THQ had a good internal reliability（the Cronbachαcoefficients ranged from 0.620

0

.762）

had a good split-half reliability（the Split-half coefficients ranged from 0.567

0

.731）.In the sub-scale

future plans with positive psychological capital（r=0.512

P

<

0.01）and actual self（r=0.513

P

<

0.01）showed significantly positive correlation.Future value with positive psychological capital（r=0.487

P

<

0.01）and actual self（r=0.457

P

<

0.01）had significantly positive correlation.Temporal self-appraisals in young students scored 0.86;the differences of temporal self-appraisals among adolescent students with different gender

residence

family financial status

grades and single or non-single child were statistically significant（P

<

0.05 or P

<

0.01）.Conclusion THQ has good reliability and validity in adolescent students and meets requirements of psychometrics

and it can be used to evaluate their temporal self-value.Contemporary young students have good temporal self-appraisals.Different gender

single or non-single child

residence and family financial status have important impacts on their temporal self-appraisals among young students.Grade One and Two in middle school is a peak for the development of temporal self-appraisals

and the sophomore year in high school is a low period for the development of temporal self-appraisals.
