Apparently abnormal Wechsler Memory Scale index score patterns in the normal population.

Interpretation of the Wechsler Memory Scale-Fourth Edition may involve examination of multiple memory index score contrasts and similar comparisons with Wechsler Adult Intelligence Scale-Fourth Edition ability indexes. Standardization sample data suggest that 15-point differences between any specific pair of index scores are relatively uncommon in normal individuals, but these base rates refer to a comparison between a single pair of indexes rather than multiple simultaneous comparisons among indexes. This study provides normative data for the occurrence of multiple index score differences calculated by using Monte Carlo simulations and validated against standardization data.

Development of the MMPI-2 cognitive complaints scale as an embedded measure of symptom validity.

Objective: To empirically-derive a new MMPI-2 sub-scale, the 13-item Cognitive Complaints Scale (CCS), as an embedded measure of symptom validity. This study hypothesized that mild traumatic brain injured subjects with financial incentives who failed performance validity tests (PVTs) would score significantly higher on the CCS compared to mild traumatic brain injured subjects with financial incentives who passed PVTs. Mild traumatic brain injured controls with no financial incentives were predicted to score lowest on the CCS.

False positive diagnosis of malingering due to the use of multiple effort tests.

Objective: Effort indicators are used to determine if neuropsychological test results are valid measures of a patient's cognitive abilities. The use of multiple effort measures is often advocated, but the false positive rate for multiple indicators depends on the number of measures used and the correlation among indicators. This study presents a meta-analysis of correlations among effort measures.

Selection criteria for internships in clinical neuropsychology.

Criteria used in the evaluation and selection of applicants for clinical neuropsychology internships were identified by a survey of programs that met guidelines for specialty training. The number of internships that offer training with specialization in clinical neuropsychology has more than doubled during the past 10 years. Supervising neuropsychologists from 75 programs replied to the survey, yielding a 72.

Rates of apparently abnormal MMPI-2 profiles in the normal population.

MMPI-2 standardization data were re-sampled using Monte Carlo simulations to estimate the base rate of apparently abnormal scores expected by chance in the normal population when multiple scales are interpreted. 36.8% of normal adults are likely to obtain a score that would otherwise be considered clinically significant at 65T on one or more of the 10 Clinical scales.
