Abstract
The author shows how the five ego states CP, NP, A, AC, and FC of TA form a balanced and complete system when there is equal energy available in each ego state. To the extent that there is a lack of energy in one of the ego states, the system is unbalanced and will evolve into a new configuration usually involving outside agents such as therapists, social workers, relatives, or other liaisons. Genograms and egograms are utilized to model families in terms of systems and subsystems. This approach provides diagnostic insights of the current state of the family system as well as predictive capability for future states of the system at critical stress points.
