If you think about the impact of asking a child if they were abused or their parent is mentally ill or chemically dependent. Those can be very difficult questions for a child regardless of their A.C.E. score. First realize the ACE questions were designed for adults to report on their childhood experiences.
Depending on the age of the child they may not know how to understand the question. If the questions are directed towards resiliency deficits then it is easier for a child to understand, It has less stigma and it gives the means to identify children who would benefit from adult supportive relationships even if they do not have current ACEs experience.
