An old issue in psychological assessment is to what extent power and speed each are measured by a given intelligence test. Starting from accuracy and response time data, an approach based on posterior time limits (cut-offs of recorded response time) leads to three kinds of recoded data: time data (whether or not the response precedes the cut-off),…

Increases in the availability of gambling heighten the need for a short screening measure of problem gambling. The Problem Gambling Severity Index (PGSI) is a brief measure that allows for the assessment of characteristics of gambling behavior and severity and its consequences. The authors evaluate the psychometric properties of the PGSI using…

Langer's theory of mindfulness proposes that a mindful person seeks out and produces novelty, is attentive to context, and is flexible in thought and behavior. In three independent studies, the factor structure of the Langer Mindfulness/Mindlessness Scale was examined. Confirmatory factor analysis failed to replicate the four-factor model and a…

Item response theory (IRT) and related latent variable models represent modern psychometric theory, the successor to classical test theory in psychological assessment. Although IRT has become prevalent in the measurement of ability and achievement, its contributions to clinical domains have been less extensive. Applications of IRT to clinical…

In this study, we examined the internal consistency and the structural validity of scores on the African Self-Consciousness Scale (ASCS), the Multidimensional Inventory of Black Identity (MIBI), and the Cross Racial Identity Scale (CRIS). Participants consisted of 225 African American college students--75 attending predominantly White institutions…

David Cooke and colleagues have published a series of item response theory (IRT) studies investigating the equivalence of the Psychopathy Checklist-Revised (PCL-R) for European versus North American (NA) male criminal offenders. They have consistently concluded that PCL-R scores are not equivalent, with European offenders receiving scores up to…

The Youth Self-Report Form's (YSR's) factor model was derived from traditional exploratory factor analytical procedures. Assuming appropriate model specification, psychometrically invariant items, and that its items provide useful psychometric information across nations omitted from its normative samples, the YSR is widely used in cross-national…

The Minnesota Multiphasic Personality Inventory--Adolescent (MMPI-A) and Minnesota Multiphasic Personality Inventory--2 (MMPI-2) True Response Inconsistency (TRIN) scales are measures of acquiescence and nonacquiescence included among the standard validity scales on these instruments. The goals of this study were to evaluate the effectiveness of…

Research on the Wechsler Adult Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) suggests that practicing clinical psychologists and graduate students make item-level scoring errors that affect IQ, index, and subtest scores. Studies have been limited in that Full-Scale IQ (FSIQ) and examiner administration,…
