I'm completing my forensic psychiatry fellowship this year. When I was applying, I did not get the sense that many programs "emphasize civil work more heavily than others." A good program will expose you to the concepts (i.e., assessment of causality related to psychiatric disorders or emotional distress; disability claims; sexual and racial harassments; competency to X, Y Z, etc.) and the relevant landmark cases. An excellent program will also ask you to review mock cases and draft reports for review. You may not ever be hired for a private case. And you may not spend much more than two to three months covering the civil case material.
The work-life balance in fellowship is a thing. Honestly, you get out of the experience what you put in. Learning the forensic report writing style and adapting your writing to it can be time-intensive. The sheer amount of record review and summarizing of records can feel endless. You'll pour hours of prep into a case and then learn the deadline moved or the evaluee cancelled. You may also be on the road a lot driving to and from isolated facilities to perform your evaluations. It can be a lot, but it can also be balanced.
If you're not wanting to jump into another year of training, then you can always utilize resources like AAPL. The journal is outstanding. The annual meetings are fun too. There's usually a seminar or two each year teaching the basics, and you'll notice that many of the current fellowship PDs teach those courses.
Are you comparing any programs specifically?
