I doubt the lying has much to do with craving attention, but of course I can only speculate about that. I often refer to what your daughter is going through as Middle School Adjustment Disorder - it very common in both boys and girls. And you are doing the absolute best thing - i.e., you are closing the loopholes so that she can be held accountable. Be sure she keeps an agenda/planning book, where she records all her assignments each day (transfer long-term assignments to a central calendar, so they don't get 'lost' in the agenda book). Also, check her homework each day to see that each assignment has been completed, and establish a uniform, standard consequence that you will implement on any occasion when she fails to be truthful.
You apparently understood my 'diagnosis' to be a clinical one. I offered it tongue-in-cheek, as I often do to help parents see that this is a frequent response to a new experience.
A text based medium like this isn't always the easiest to pick up humor on, and I did not know you were joking.
Again, my apology for misinterpreting your answer.
One evening we went out for dinner. Our 11 year old foster daughter (chronic lying problems!) said she wanted to eat salad bar. We lightly ordered her pizza and fries. When her food arrived she was furious and exclaimed that this is not what she asked for. Without sarcasm at all, I just told her that I know she said salad bar. But since she lies so very often, we thought that she lied when she said salad bar and decided that she probably meant she really wanted pizza and fries.
We were not conflicted about her lying, but she sure was! When at the store I would buy the blue shirt instead of the pink one. Instead of the requested ice cream for dessert she got a bowl of cereal. Because we coul not believe her when she said stuff....
Our foster daughter is very truthful now. She still refers to that technique as one she really hated but she tells me now that it really made her want to stop lying "because it makes sense now why it is bad".
I hope this helps...
