For assessing outcomes and doing longitudinal research, how can deviance on the adult scales be analyzed in relation to deviance on the older 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 adult scores and their subsequent older adult scores, relations between the earlier and later classifications can be analyzed via chi-squares, kappas, and odds ratios, as well as via correlational and logistic statistics.
