Background and Purpose: The validity of the content can be determined by its validity. The usefulness of the sampled content from a certain domain determines the content validity of an instrument. This study aimed to establish a model the content validity of a questionnaire assessing the "Organizational Hierarchy" domain using a systematic approach based on the 6C Model and Content Validity Index (CVI).
Method: Content validation was conducted in six stages, as per the 6C Model: Creating a form for content validation, choosing an expert review panel, completing content verification, Considering the objects and domain, causing a grade for each item, and CVI Calculation. The panel of experts assessed the relevance of 18 items using predefined criteria.
Results: The results indicated high levels of content validity. Item Content Validity Index (I-CVI) scores revealed unanimous agreement among experts for most items, with I-CVI scores of 1. The Scale-Level Content Validity Index Using Average Method (S-CVI/Ave) was 0.94, demonstrating strong consensus among experts. The Scale-Level Content Validity Index based on the Universal Agreement method (S-CVI/UA) was 0.78, indicating substantial but not complete agreement.
Conclusion: Content validation is a critical step in ensuring the overall validity of assessments, and this study provides a structured and evidence-based approach for researchers. By following the 6C Model, researchers can establish the Content Validity Index (CVI) for their questionnaires, contributing to the credibility of their instruments. The findings underscore the importance of rigorous content validation in questionnaire development and measurement instrument assessment.
