The index of the reliability of the scale（α）was .88 and the split-half reliability（Spearman-Brown formula）was .83. Test-retest reliability, two and half month interval, was .72. Validity of the scale was estimated by the concurrent validity. The correlation between two kinds of prosocial scales（1, 2）and SRS were .55 and .57. The correlation between empathy scale and the SRS was .57. The correlation between cooperation scale and the SRS was .49. Validity was also tested by peer evaluation.
