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

The objective of the present study was to know the psychometric properties of the Ned Herrmann test, HBDI (Herrmann Brain Dominance Instrument, 1989), in the Spanish version, which has been widely used in the field of education and organizational management. The HBDI is based on the Whole Brain model, which states that people have four thinking styles, related to the cerebral hemispheres and the limbic system. Method: Two exploratory and confirmatory factor analyzes were carried out on responses from 578 students from a business-oriented university. Results: In analysis 1, it was revealed that, of the 40 items of the Herrmann test in the Spanish version, they were reduced to only 11 items. In analysis 2, the results offer a new model, where the four dominance subscales have 2 indicators, reducing the questionnaire to only 8 items. Both analyzes showed the construct validity of the instrument Conclusion: The results show that this instrument in the Spanish version is reliable and valid. It offers the academic community a consistent tool to evaluate the thinking styles of business-oriented young people, in addition to being friendly, short and easy to administer.
