Ego State Therapy is a psychodynamic approach to treat various behavioural and cognative problems within a peron. It uses techniques that are common in group and family therapy, but with an individual, to resolve conflicts that manifest in a 'family of self' within a single person.
A specific ego state is a group of behaviours and perceptions which exhibit 'the self' in a given situation. For example one ego state may be 'the self' at work, another 'the self' in relation to a parent. The 'self' at work may be confident, enthusiastic, energised yet the same person in relation to an elderly parent might show very different characteristics and emotions. They are in a different ego state.
If a client is unhappy with their experience of a particular relationship or finding it difficult to function in specific environments, then Ego State Therapy may be an appropriate choice of therapy.
