Validity of preschool disruptive behavior disorders, NIH/NIMH, R01 MH62437 The Chicago Preschool Project seeks to evaluate the validity of diagnostic constructs in early childhood with a focus on externalizing disorders (including oppositional defiant and conduct disorders).  By examining a preschool cohort, C.P.P. will be able to determine if ODD and CD can be validly diagnosed in younger children, differentiating developmentally normative behavior difficulties from atypical or deviant behavior.
