If I could find one for my kid to participate in, I wouldn't hesitate.

We are considering participating in a study at the NIMH. It's a big time commitment (weekly visits) to NIH because there's a therapy component to the study. So, we've been impressed (screening process). Their staff knows what they are doing and they have been very receptive. If your child has participated in a study with the Emotion and Development Branch, I would be interested to receive some feedback on what your experience was like.
