I think that mine would have me check in with him. I was having a hard time a few weeks ago and he wanted me to contact him between sessions. Since I could not guarantee that I would do that, he had me start seeing him twice a week. This was temporary and this will be my last week before I go back to once a week. I am glad that he did it this way. I don't think that I would be able to answer the phone if I knew he was checking in on me.

I am not certain, but I think that SI is usually used for self injury.
