I want to add this link to this forum since DID is my primary issue. My T uses CBT with me as a part of the DID help. This link has worksheets you can use if your T uses CBT: http://www.getselfhelp.co.uk/freedownloads2.htm

For us, we actually work with each alter through the different issues. Having them fill in the worksheets as each one might allow T to see how each alter interprets a situation in a different way.
