This article presents the scientific validation of a Management Model for International Cooperation aimed at the development of renewable energy sources in the Cuban electricity sector. The objective of this research is to validate the content of the developed questionnaire, thus obtaining an instrument with 22 activities and five subprocesses for application in the management of international collaboration projects. The methodology used was quantitative, descriptive, and psychometric, with content validity based on expert judgment, employing statistical treatment using the Statistical Software for the Social Sciences (SSPS V.20). It is concluded that the results show high internal consistency of the construct, where Cronbach's alpha values greater than 0.90 are considered optimal in all subprocesses of the model, confirming its relevance and reliability for the strategic management of international renewable energy projects.

Cuba is driving its sustainable energy transition with renewables as the central axis, although the Cuban government estimates that substantial investments will be necessary to achieve this goal. This work presents a proposal for a Management Model of International Cooperation for the Development of Renewable Energies, aimed at mobilizing the required funds. The model was designed through a structured questionnaire with 7 dimensions, 22 activities, and 5 subprocesses to guide the collaborative management of projects. The methodological approach was quantitative, descriptive, and psychometric, ensuring content validity through expert evaluation and statistical analysis. Reliability was established through internal consistency measures, while construct validity was supported by an exploratory factor analysis, confirming its feasibility and coherence. The validated questionnaire confirms its methodological rigor and practical utility, favoring the subsequent implementation of the model for Cuba’s transition toward green energy.
