Resilience is a dynamic process, through which, a person succeed to adapt to various lifetime adversities. Resilience perception and conceptualization have been changed through time. The resilience significance, broadening and components knew continuous changes, its complexity making difficult to develop thorough and standardized studies. The study of resilience went through several stages, trying to identify the factors involved in resilience, its explanatory processes and mechanisms and to develop interventions that enhance resilience. The lack of consensus on definition of the construct, the existence of multiple, various elements of resilience, the numerous measures meant to quantify resilience cause confusion within the field and ignite criticism of resilience theory. There is a need in the scientific realm for construct clarification for practical application and evaluation.
