The authors examined the predictive validity and construct equivalence of the three major procedures used to measure assertive behavior: self-report, behavioral role-playing, and in-vivo assessment. Seventy-five subjects, who spanned the range of assertiveness, completed two self-report measures of assertiveness, the Rathus Assertiveness Scale (RAS) and the College Self-Expression Scale (CSES); two scales from the Endler S-R Inventory of General Trait Anxiousness, the interpersonal and general anxiety scales; eight role-playing situations that involved the expression of positive and negative assertiveness; and a telephone in-vivo task. In general the study revealed the following: assertiveness measures are task-dependent in that there was more overlap within task than between tasks; there is a moderate degree of correspondence between self-report and role-playing measures, although this was true only for negative assertion; positive and negative assertion do not appear to have the same topography of responding; and there appears to be no consistent relationship between the in-vivo measure and any other type of assertiveness measure.
