For assessing outcomes and doing longitudinal research, how can deviance on the school-age scales be analyzed in relation to deviance on the adult scales scored later for the same individuals?

Answer: The profiles for all the instruments provide criteria for classifying scores as being in the normal, borderline, or clinical range. If people are grouped into these categories according to their school-age scores and their subsequent adult scores, relations between the earlier and later classifications can be analyzed via chi-square, kappa, and odds ratios, as well as correlational and logistic statistics.
