Answer: For evaluating a particular person, T scores are helpful for indicating the degree to which the person deviates from normative samples of peers on each scale. However, for statistical analyses of adaptive functioning, syndrome, DSM-oriented, 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 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 the age group in the sample that is being analyzed. Chapter 11 discusses the different uses of raw scores and T scores in detail.
