In your relationship with your child, you will have one of two attitudes towards everything you hear her say or see her do - acceptance or unacceptance.* When you feel unaccepting of the behavior (placing it below your line), YOU OWN THE PROBLEM. to solve it, you will want to take appropriate action to change that behavior somehow so that it becomes acceptable to you. P.E.T. teaches some powerful tools to do that effectively without damaging the relationship.
On the other hand, some of your child's behaviors which are acceptable to you - and thus do not cause you a problem - are indications that the child has a problem.
Examples: you hear the child crying or saying, "I don't have any friends." These behaviors are placed above the line in the window, but in a special area at the top; they are not causing you a problem, but indicate that something in the child's life is unacceptable to him. Now the child owns the problem.
P.E.T. teaches an entirely different set of skills for helping the child take the responsibility for solving her own problems.
And, finally, all the behaviors that are acceptable to you and are not cues or clues that the child has a problem are placed between the two "problem" areas in a space labeled "NO PROBLEM AREA." P.E.T. also teaches skills and concepts for enhancing your relationship with your child in this area.
The purpose of p.E.t. is to enable parents to enlarge the NO PROBLEM AREA in their relationships with each of their children through the use of skills - to help the child take charge of the problems in her life and to enable the parent to solve her problem when her child's behavior is unacceptable.
