the forms sound like the dbt ones... it's not meant to be a deterrent, but to help you understand exactly what goes on when, and help to get to a point where you can change the behavior before it escalates to self-harm... (or so they say). I hated them immensely and always felt like it was a punishment. I stopped going to DBT, and have refused it every time it's been suggested again because it's a bigger trigger for me than a help. (actually, I was kicked out every time except this last time... every other time I screwed up so bad they didn't want me there anymore because they realized it did more harm than good. This last time the group dwindled to too few participants so they stopped it... It was actually one I liked finally. go figure).
Maybe having a frank conversation about your unwillingness to stop the self harm at this point would be a good idea? I know they can't endorse self-harm, but some therapists will then focus treatment on something else. I have had therapists do that in the past - we worked on the other stuff and there was an understanding that they would ask every few sessions how the self-harm was going, and I would agree to get checked out by a dr or nurse if it got too bad. we also had the agreement that I would not lie about the self-harm if asked directly, nor would I omit any information. It helped me focus less on that negative coping and feel safer in being able to talk about it when I was asked. I don't know if that's feasible for you, but thought I would throw it out there that it is possible and may be worth a conversation...
