An assertion inventory for use in assessment and research

Abstract

The Assertion Inventory is a 40 item self-report inventory which permits respondents to note for each item their degree of discomfort, their probability of engaging in the behavior, and situations they would like to handle more assertively. Normative data from a college population as well as data from women taking part in assertion training groups are included. Comparative distributions of these populations over four combinations of response probability and discomfort scores are presented as well as reliability and validity data. The value of the Inventory both in clinical settings and in research is discussed.
