Abstract
50 male residents of Nova Scotia from 20 to 70 chronological years old were paid volunteers in a test-retest study of the Adult Growth Examination (AGE) test of bodily aging. With test-retest intervals of from 1 to 8 wk., the product-moment correlations of reliability were .88 full test, .75 systolic blood pressure subtest, .92 hearing level subtest, .93 near vision subtest; the standard error of measurement of body age was 4.98 yr. AGE full-test Body-age scores correlated .81 with chronological age. Additional subtest correlations and inter-correlations are made and comparisons with results from other samples and related research are included. All correlations were high and significant ( p = .01).Keywords
