Ego State Diagnosis
It is helpful to be able to assess or diagnose which Ego State in the Structural Model, or which mode in the Behavioural Modes model, somebody is in. In this way we can respond appropriately as well as ensure which mode we are addressing However, when we work with other staff or are relating with young people, we are responding on the behavioural level. It is not always possible, or appropriate, to be undertaking more in-depth types of diagnosis. I have outlined them here though so that an understanding of the complexity of the process can be achieved.
Behavioural Diagnosis: Words, tone, tempo of speech, expressions, postures, gestures, breathing, and muscle tone provide clues for diagnosing ego states. Parent mode words typically contain value judgments, Adult words are clear and definable, and Free Child mode words are direct and spontaneous. For example, a person in Adapted Child mode may cry silently, whereas when in Free Child mode we are likely to make a lots of noise. "You" or "one" usually come from Parent. This can switch even mid-sentence. If we are leaning forward it is likely we are in the posture of the Parent mode, whereas if we are in Adult mode we tend to be erect. These are indicators not guarantees. Assessment needs to be supported by other methods of diagnosis.
Social Diagnosis: Observation of the kinds of transactions a person is having with others. For example, if eliciting a response from someone's caretaking Parent it is likely that the stimulus is coming from Child, though not necessarily the Adapted Child mode. Our own responses to someone will often be a way of assessing which ego state or mode they are coming from.
Historical Diagnosis: The person's past also provides important information. If, as a child we had feelings similar to those we are experiencing now, it is likely we are in Child ego state. If our mother or father behaved or talked in the same way that we are behaving or talking now then we are probably in a Parent ego state.
Phenomenological Diagnosis: This occurs when we re-experience the past instead of just remembering it. This means that diagnosis is undertaken by self-examination. This is sometimes accurate and sometimes very inaccurate as the Child ego state may be afraid to allow our Adult to know what is going on.
