Adolescent Assertiveness Assessment Scale: Evidence of Content Validity

Abstract

This study aimed to present the process of elaborating the Adolescent Assertiveness Assessment Scale (AAA-S). Based on the analysis of judges, evidence of the validity of the content of the instrument was established, assessing the criteria of relevance, pertinence, and clarity of the items. In addition, a study with a sample of the instrument’s target population showed good indices for the comprehensibility of the items (semantic validity). Based on these results, the illustrated version of the instrument was elaborated, which underpins the general scope of the psychometric study on the construct validity and accuracy of AAA-S and sheds light on the development of new studies on the factorial validity of the instrument.
