A revision of the A-S reaction study (form for women) is reported, together with new data concerning the reliability, validity, and uses of the scale with both men and women. 11 years of experience have shown that the test is useful for vocational guidance, personal counselling, and psychological demonstrations. The scale defines and measures a biosocial continuum, serviceable for comparative studies within the field of practical psychology, but too coarse in its construction to represent adequately the subtleties of individual traits within the single personality. Various published studies agree in finding negligible relationship between ascendance-submission and intelligence, a correlation of approximately .35 between submission and introversion, and a correlation of .44 between ascendance and persistence.
