Ratings of Self-Status International, a scale designed to measure behavioral and attitudinal correlates of fertility control, was administered to 95 undergraduates on two occasions four weeks apart to estimate the stability of the 12 measured factors. The test-retest correlation of scores from the two times was .58. Ten of the 12 factor scores had estimates of stability ranging between .48 and .69, but two factors yielded coefficients of .23 (p < .05) and .32 (p < .01) only, indicating need for revision or reformulation.
