Answer: For evaluating a particular adult, T scores are helpful for indicating the degree to which the adult deviates from normative samples of peers on each scale. However, for statistical analyses of adaptive functioning, syndrome, DSM-oriented, substance use, and Critical Items scales, raw scores should be used because the T scores are truncated, as explained in Chapters 6 and 7. For statistical analyses of Internalizing, Externalizing, and Total Problems, either raw scores or T scores can be used because they will usually produce similar results. If different gender/age groups are combined in the same analyses, it may be useful to standardize scores by gender within age group. Chapter 14 discusses the different uses of raw scores and T scores in detail.
