There have been many threads related to interventions in the Alcoholism & Newcomers sections of these forums. One of the things that helped me in my own education about addiction was reading in all the forums to get a sense of perspective from all sides.
Here's a recent thread that you may find interesting - especially the "compliance vs surrender" theory that is discussed on page 2. (by Psychologist Dr Harry Tiebout) This theory holds water to me in regards to recovery across the board, regardless of what a person is suffering/recovering from.
