Zusammenfassung:The reliability of the 30-item Modified Rathus Assertiveness Schedule (MRAS) was examined using the test-retest method over a three-week period. The MRAS, which was administered to 103 white middle-class seventh graders, yielded correlations of .74 using the Pearson product and Spearman Brown correlation coefficient. The correlations for males yielded .77 and .72 using the Pearson Product and Spearman Brown techniques, respectively. For females the correlations for both tests were .72. Paired t tests by sex indicated no significant change in MRAS scores between test administrations. These findings add to the existing information on the reliability of the MRAS.
