The Queens College Preschool Project (QCPP) is a federally-funded five-year study designed to distinguish inattentive/hyperactive preschool children who develop Attention-deficit/Hyperactivity Disorder (ADHD) from those who do not.

The ability to distinguish between these two groups of children might help to identify children for whom early intervention is warranted, and shed light on potential treatment strategies.
