In the office of a therapist treating adolescents we encounter issues of teenagers breaking their parents trust. When the violation occurs the parents are frequently heard to say "I will never to able trust you again." Or the other response is "until you are 18 or maybe 30." Families are sometimes resistant to instructing the child in how to earn trust back. They tell me that if I tell them what to do they will just do it and how will I know if it is real? If we remember that if we ask someone to do something and they do it that indicates they are trying to do the right thing. This violation of trust is not the only mistake the teenager will make. When a teenager keeps making the same mistake then the consequence is not good enough or there is another issue and professional help may be indicated. But basically teenagers want things to be good between themselves and their parents. It is like a light bulb going off when a teen says to be "I think I get it. If I do what they tell me, go to school and do my homework I can just about do what I want."
So to create a trust building plan. It of course depends upon the violation. But basically following the consequence there should be a planned reinstatement of the violated privilege, returned slowly with monitoring. For example, if the child is not where they say they will be the parents will check up on them with decreasing frequency until they feel they have gotten this. Then sporadicly they check a bit longer on a random basis. If they violate internet privileges it it the same process. Check their websites with decreasing frequency to know they are following the rules. I also tell the kids that if you mess up again don't try to hide it. Go to your parents as soon as you get home and say I violated the rules tonight, This is what I did. There will be a consequence and reduction in freedom but it will not be a bad as trying to hide it. They are sometimes slow to learn that parents always find out. Teen are a bit slow to accept this but I convince them (and the parents) the the consequences will be less if they tell the truth.
As always I feel we need to give our kids lots and lots of positives even when or especially when we are upset with them.
Good luck with this. Sherri
