Development of the Children’s Assertive Behavior Scale for Preschool Children:Examination of Its Reliability and Validity

Abstract

This study aimed to develop a redacted version of the Children’s Assertive Behavior Scale (CABS) for use with preschoolers, and to examine the devised scale’s reliability and validity. A total of 270 children (113 in the second year; 157 in the third year) participated in Study 1. Factor analysis revealed a single-factor structure, with a significant test – retest correlation. In Study 2, with 27 participants (14 boys and 13 girls; all in the third year), we examined the criterion-related validity by evaluating the correlation between assertion and empathy. Results showed a relationship between assertion and empathy, supporting our hypothesis. In conclusion, these findings suggest that our adapted version of the CABS for preschool children appears to have adequate psychometric validity and reliability.
