The pre-test(Mar. 20th. 2014), after-test(Jul. 17th. 2014), and later-test(Sep. 25th. 2014) were implemented in order to verify the effectⅣeness of the program. Eventually, the date of 29 students(14 for the play-based group, 15 for the control group) were analyzed to verify the effectⅣeness of the program. The date were analyzed by using SPSS 18.0. To know the difference of the two groups. the score of the after-test and later-test was analyzed by ANCOVA.

And play-based group therapy program had significant effects on decreasing the helplessness of the elementary school students.
