Assessing treatability in mentally disordered offenders: A conceptual and methodological note

The assessment of treatability in mentally disordered offenders has rarely been addressed through empirical research, despite its frequent use in clinical and legal decision-making. We describe four necessary steps for establishing the requisite research base for treatability evaluations: (a) criterion specification, (b) the development of reliable measures, (c) the validation of these measures with treatment outcome data, and (d) the incorporation of environmental and base rate information.

Use of local norms to improve high-point code-type concordance of two short forms of the MMPI

Criticisms of short forms of the MMPI have been based on claims of unsatisfactory high-point code-type concordance rates. The use of local norms has been suggested as a possible solution for these low concordance rates. In this study local norms for three client populations were developed for the MMPI-168 and Faschingbauer's abbreviated MMPI. These local norms did not significantly increase high-point code-type concordance. Possible explanations for these findings are discussed and suggestions for future research offered.
