The organizational culture studies date back to the 1980s, where its leading exponent, Edgar Schein, proposed the analysis of three fundamental variables to understand the culture of an institution: character, appearance, and personality. This last aspect has taken on greater relevance, since disorders arise as the need to analyze and explain the influence that the intrinsic characteristics of individuals have on the way they develop and interact with their environment. In this context, the present research aims to determine organizational personality and its contribution to hierarchical culture in military entities in Ecuador. For this purpose, a mixed approach will be used: quantitatively, the application of the Exploratory Personality Questionnaire (CEPER); and qualitatively, documentary analysis and the Delphi method expert judgment technique will be used to validate the instrument. The design is non-experimental, cross-sectional, and has a descriptive and exploratory scope. The sample is made up of members of Ecuador's military institutions, chosen using simple random probability sampling. The information will be processed with SPSS v.27 and Microsoft Excel software. For the analysis of the results, the exploratory factor analysis technique and the structural cross-impact matrix will be used. The results show that borderline personality disorder is the predominant disorder in this type of institution; likewise, it was determined that eleven of the fourteen types of personality disorder (78.57%) contribute to the hierarchical culture. The presence of these disorders can have an impact on decision-making, power management, internal communication, and esprit de corps.
