To demonstrate this expertise, the contributions of Jean-Claude Abric and Armando Alonso were epistemologically integrated; the tool used was the Natural Semantic Networks psychological test. It is necessary to clarify that this procedure was validated by expert criteria. In addition the effectiveness of the praxis was confirmed thanks to the interviews with the parents of the adolescents after the psychosocial intervention. This expertise can be applied to adolescents to prevent other scourges of humanity such as: prostitution, violence, human trafficking, slavery, terrorism and organ trafficking, where it would be based on the singularities of each country or community.
