“…These models for assessing drug response were developed primarily for specialized clinics, and with the exception of obtaining behavior rating scales from teachers (their one common feature), have not incorporated a high degree of school involvement in the assessment procedure, although there are some exceptions (e.g., Gadow et al, 1991;Neisworth et al, 1976;Slimmer & Brown, 1985). Further, they vary greatly with regard to the use of placebos, doses and schedules of medication, measures of therapeutic drug response and side effects, and their implicit rationales for treatment, all of which makes comparisons extremely difficult.…”
