I just logged onto your site for the first time and wonder if your tips can help us- a single parent with a 15 year old son who matches most of the factors you list in the behavior list AND as a result we are seeking residential placement before he does something really bad. He is a kid with great potential in spite of a low IQ and a school system, which is not meeting his needs. He has NVLD, which is not recognized by the school, and I cannot get them to understand that he needs different accommodations, not isolation in a special-ed classroom, which he hates.
Of course my bias would be to err on the side of trying the parenting strategies in my ebook first. Unless you will be sending him to a boarding school for at least a year, you will be wasting a lot of time and money on placement.
Keep in mind that I counsel kids who are struggling [just like your son], and I also work for a youth center that has 4 residential facilities. What I see is that the kid does very well while in placement, but if the parent has not made any changes on her end, the kid's "positive behavior change" has no longevity -- with a few short weeks after returning home, I see the behavior problems reappear with one negative caveat - the kid has been associating with other delinquents, and is a better "criminal thinker" as a result.
