Unfortuantely, my plans to develop a simple Web- and app-based autism evaluation tool for concerned parents has hit a snag: the American Psychiatric Association denied my request to use their DSM criteria for autism as the basis for the tool. However, hope is not lost: I have some ideas about how I might incorporate other diagnostic criteria into the tool, and in the process make it an even more robust and interesting experience. It's not back to the drawing board, but onward and upward.
