How is Erikson's theory applicable to working with children and families now?

Erik Erikson's psychosocial development theory emphasized the idea that the man must face several life stages in order to gain confidence and mental health, those stages are:

Confidence vs. distrust, which main support is his own mother. Autonomy vs. shame and doubt, related with parents. Initiative vs. guilt, developed in hand with basic family. Laboriousness vs. inferiority, with his neighborhood or school. Exploration of identity vs. identity dissemination, during his adolescence with friends or pairs. Privacy vs. isolation, develop the search and need of privacy. Generativity vs. stagnation, in this life stage, the person looks for family company. Integrity of the self vs. despair, it occurs between the older age and the death.
