Development and Validation of the Children's Assertiveness Inventory

Abstract

The development and validation of the Children's Assertiveness Inventory are reported. Psychometric properties of the scale are detailed for the normal samples of grade school children and one sample of socially withdrawn children. Initial analyses indicate that the scale possesses high test-retest reliability and acceptable stability over time. Further, it adequately discriminates between normal and withdrawn samples, has acceptable convergent and discriminant validity, and possesses a meaningful factor structure. The potential research and clinical utility of the scale is discussed, and important social and developmental issues affecting the expression of assertiveness in children are addressed.
