The boy that you wrote about reminds me of many of the children that I work with. The situation is also very similiar to many of my cases. I strongly believe that the aunt must be interviewed by the psychiatrist evaluating the boy to have a complete picture of the boys behavioral and emotional presentation. If the concerns of the case worker are that the aunt's input may be misleading then your assessment of the aunt, other sources of feedback regarding the boy (such as teacher or other caregiver) should be considered. Making a plan for treatment both in therapy and for psychopharmological intervention can not be made without input from caregivers. In fact a diagnosis of ODD (or depression along with ODD in this case) can not be substantiated without caregiver's remarks. The fact that the boy is not responding to typical parenting techniques appears to represent to me a manifestation of the boy acting out a negative self identity that has been incorporated by the abuse introject. In his defensive functioning to relieve the anxiety of the abuse introject he projects the negativity onto the caregivers. Through play therapy and working with the caregiver this can be addressed and the client can integrate a more healthy and balanced view of himself.
