I had to see a forensic psychologist about four or five years ago. I had already been on social security disability for over three years and SSA was reviewing my case to make sure that I still qualified for disability. After receiving all of the requested information from myself, my husband, my doctor, etc. they wanted me to see a forensic psychologist who was independent from my case.
As I recall, he had a regular therapy practice but he also saw clients specifically for disability and other court related evaluations. He did not ask me to go through the details of my personal history. He needed a general idea but no details. His main interest was in how I was presently functioning and determining if, in fact, that qualified as being disabled. I found him to be knowledgeable, understanding and compassionate. Before going to the appointment I had feared his goal would be to somehow prove that I wasn't disabled but it didn't feel like that at all. In fact, there were questions about symptoms that he asked and I sort of blew off at first because they were symptoms that I had lived with so long I didn't really recognize them as being a big deal or being "not normal". He was very compassionate but asked more detailed questions about those daily functioning sorts of things because he saw around the fact that I was minimizing it and recognized that there was a problem there.
It all worked out. I still continue on disability. And what I really found was that all of the dread that I felt for the weeks/months leading up to that appointment were for nothing. Like many things, it wasn't nearly as bad as I had built it up to be in my mind.
