I imagine it varies by pdoc - mine asked me basic medical history questions, more detailed emotional/family history/personal history questions, then he asked me about what I was currently experiencing (anxiety and depression), how those manifest for me, what I want out of treatment, and we talked about options. My initial appointment was over an hour long, but it was just lots of information gathering on the pdoc's part and me asking questions of him and talking about options. Also, I had my therapist call him prior to my appointment, so she gave him her thoughts, some of my background, etc before I even met him.

Having my T call my pdoc first was so helpful for me. She was able to give him the basics on me and she was able to share with him the things that I wasn't able to in that first appointment.
