Test-retest reliabilities of the Revised Children's Manifest Anxiety Scale over 1- and 5-wk. intervals were examined for two samples of students, 73 boys and 88 girls in regular sixth, seventh and eighth grade classrooms (11 yr. to 14 yr.). For raw scores the test-retest Pearson r was .88 (1-wk.) and .77 (5-wk.), indicating good reliability. For both samples there was a small difference between test (12.2 for 1-wk. sample; 11.4 for 5-wk. sample) and retest (11.2 for 1-wk. sample; 9.8 for 5-wk. sample) mean raw scores. Implications for test use are discussed.
