"Psychometric Evaluation of the Whole Brain Model: Adaptation of the HBDI for Business Students"

Abstract

"Introduction: The Herrmann Brain Dominance Instrument (HBDI) is an instrument designed to assess cognitive preferences based on the Whole Brain Model (logical-analytical, sequential-organized, interpersonal-emotional, and holistic-creative quadrants). Despite its international application, a validated adaptation for the Latin American context is absent. Aim: This study aimed to evaluate the psychometric properties of the Spanish adaptation of the HBDI (Jiménez, 2006) within a Latin American university student population. Methods: Data from 578 business university students were subjected to EFA to examine structural validity, internal consistency analysis for reliability, and a CFA to confirm the simplified factorial structure. Results: EFA yielded a reduced 11-item structure in Study 1, which was further refined to an 8-item solution (2 items per quadrant) in Study 2. Discussion/conclusion: The findings indicated robust factorial validity, and acceptable internal consistency for each subscale provides evidence of the adapted HBDI for use within Latin American university settings. © 2026 The Author(s), 2026.
