It is quite difficult to determine the degree of family functionality. The degree of family functionality, can be determined by the clarity of the family boundaries, which need to be well defined but also flexible. Thus, it is necessary to have interactions by respecting the individuality of the person, emotional support and encouragement from the family to manifest their own personality, in order to be able to shape and then to define their own identity. Focusing on the child and receiving it with unconditional love, contributes to the creation of the feeling of self, a feeling that brings safety, validation, confidence and freedom to evolve psycho-emotional. The family availability to meet the needs of the child in an interval of frustration tolerated by the child, contributes largely to the development of a friendly personality, with a high self-esteem, open to new, autonomous, self-respect and respect for others, inclined for personal growth and evolution.
