The highest score will show you the defence you most typically engage in. The lowest one, indicates the defence you engage least in, etc.
The absolute score tells you something about your level of defensiveness: are you very well defended in general (scores 7,8,9,10), or are you well on your way to relinquishing your defences (scores 1,2,3,4)? The higher your scores, the more often you feel a need to defend yourself. This means that there are still many things that are symbolic for you. Many different situations or people will make you shift consciousness from Adult Consciousness (AC) to Child Consciousness (CC), resulting in your being in CC a lot of the time. In this case, beware of what you think is true about others, yourself, what you need and what is important. After all, when we are in CC or defending against the old pain we cannot trust that our perceptions constitute an accurate representation of the present.
To test whether you are making progress with your PRI-process, it is advisable that you do this test from time to time and compare the scores.
