Ratings of Self-Status International, a scale designed to measure beha
vioral and attitudinal correlates of fertility control, was administer
ed 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 yi
elded coefficients of .23 (P<.05) and .32 (p<.01) only, indicating nee
d for revision or reformulation.
