A scientific model is an abstract, conceptual, graphic, physical and/or mathematical representation of systems, objects, phenomena and physical or social processes, which seek to analyze, describe, explain, simulate those systems and phenomena or processes presented in a real situation. The models are developed through an iterative process that allows determining a final result based on input data, in which empirical evidence allows us to review and modify their basic assumptions. In our case, the nursing profession, in Spain, the current models are given and we try to fit our reality into them. Considering our own objectives, it is necessary that our models adjust to the reality situation they conceptualize, since it is different. Every model must be built from specific concepts and relationships in an adaptation to the reality that each professional and nurse lives. In our case, we talk about the context of each nurse, the cultural situation in which the communication and interrelation processes are carried out, relying on epistemological and ontological bases, and being knowledgeable about the conceptual elements that give meaning to the profession.
