Finkelhor's article gets at the lack of empirical evidence that shows the benefits of the screening, something I know very little about.** But I too am finding a lack of empirical research that measures outcomes. For my own work, I was hoping to find something more than stories (lots of them, yes) that showed the benefits. I do qualitative research so I know the power of a story. But academic research requires certain standards that mean doing the work of setting up a study to track and figure out what measures to look for, find a sample... Seems all the people doing this good work, there'd be somebody out there studying it.
**[I was a little bothered by how little regard (or credit) he was giving people who could take this new self-knowledge and act on their own behalf -- maybe with or without professional mental health help but there are other resources people can and do rely upon.]
