The S-R Inventory of Assertiveness

The S-R Inventory of Assertiveness was designed to assess assertive behavior in light of three factors (situations, modes of response, and subjects). It was written by the author and administered to a college student sample. Results indicated that males scored higher than did females. However, females tended to score higher on positive assertion situations, with males scoring higher on negative assertion situations. Test-retest reliabilities were high for mode of response and total scores. Concurrent validity was assessed by correlating the total scores with the College Self-Expression Scale. Validity coefficients were moderately high (males, r = .594; females, r = .704). The results of a components of variance analysis indicated that situations and the subject X situation interaction, accounted f or a large proportion of the variance in reported assertive behavior
