Tellegen et al. (2003) proposed fundamental changes in MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scale development by discarding empirical scale development in favor of construct validation via Jackson's (1970) sequential system of scale development. As a result of their efforts, a general distress factor (Demoralization) was identified and 8 Restructured Clinical (RC) Scales were developed. Using 7,330 clinical cases from Caldwell's (1997) data set, in this study, we sought to cross-validate the MMPI-2 RC Scales. Scale homogeneity was confirmed with high alpha coefficients and interitem correlations in the expected range. We also achieved a major objective of reducing interscale correlations. In replicating Tellegen et al.'s principal components analysis, we achieved a high concordance for 6 of the 8 RC Scales. We critically examine these results in light of Jackson's construct validation. We discuss the clinical usefulness of the MMPI-2 RC Scales within the context of current and future research.

The development of standardized assessments for competency-to-confess evaluations has remained largely neglected for the last several decades. Groundbreaking research was conducted on Miranda waivers during the late 1970s, but researchers have failed to sustain programmatic research. This critical review focuses on four published Miranda measures (Comprehension of Miranda Rights, Comprehension of Miranda Rights-Recognition, Comprehension of Miranda Vocabulary, and Function of Rights in Interrogation). When evaluated by contemporary standards, the validation of these measures is very limited. Major improvements are needed for interrater reliability, test-retest reliability, content validity, construct validity, and criterion-related validity.

Forensic evaluations of offender populations often consider psychopathy as an integral component of these consultations. Vexing issues remain of whether psychopathic traits should be evaluated consistently irrespective of demographic characteristics (e.g. gender), comorbidity (e.g. other Axis II pathology), or setting (e.g. jail or community). The current study examined gender differences for psychopathy and Axis II traits in a nonreferred jail sample of predominantly nonviolent offenders. Participants with moderate to high levels of psychopathy evidenced substantial comorbidity, especially with Cluster B personality disorders. Facets of psychopathy and Axis II traits varied substantially across both genders. In addition, the research evaluated Lynam's Hyperactivity, Impulsivity, and Attention difficulties (HIA) model of psychopathy. These initial data found little support for the HIA model in this jail sample. In testing competing hypotheses, the HIA model was substantially better at predicting Cluster B traits than psychopathy per se.
