It sounds like you want more information on the topic rather than a look at outcome research in the area...And unfortunately I haven't heard of functional communication training before now. It sounds similar to dialectal behavior therapy (Linehan) and most particularly seems similar to the adaptions of DBT that I have heard Charles Swenson present. You might try looking on the discussion forum by Jessica Broitman on control mastery theory to ask her opinion on the topic. Just click on index to get to that forum. Best of luck in tracking down the right answers. Ellen
