Previous study claimed that the prosocial behaviors endorsed by Chinese adolescents were constructed of four dimensions：altruism，commonweal-social rule，relationship，and personal trait.First，based on the four-dimension structure，we develop the preliminary Prosocial Behavior Scale for Adolescent（20 items）. 580 adolescents（pupils and junior students，51.0% were boys）in Sichuan Province participated in the preliminary test. Then the item analysis and factor analysis were used to develop the formal scale. 4309 adolescents（pupils，junior and senior students，47.6% were boys）recruited from five different districts in Beijing completed the 21-item formal scale. After revising，the final Prosocial Behavior Scale for Adolescent contains 15 items. The results indicated a good reliability and validity：（1）consistencies for each dimension and total scale were satisfactory；（2）the EFA showed that a four-factor model fit the data well，and the CFA suggested an acceptable structural validity. This study revalidated the four-dimension structure of prosocial behaviors in Chinese adolescents，and developed an appropriate Prosocial Behavior Scale for Adolescent.
