The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory factor(More)
The California Verbal Learning Test - second edition (CVLT-II) is one of the most widely used neuropsychological tests in North America. The present study evaluated the 1-month test-retest reliability and practice effects associated with the standard and alternate forms of the CVLT-II in a sample of 195 healthy adults. Eighty participants underwent repeat(More)
This randomized, double-blind, placebo-controlled, 6-month trial examined the efficacy and safety of once-daily morning-dosed atomoxetine in adult patients with attention-deficit/hyperactivity disorder (ADHD) and the efficacy of atomoxetine in ameliorating symptoms through the evening hours. Patients received once-daily atomoxetine (n = 250) or placebo (n =(More)
OBJECTIVE To assess the effect of atomoxetine on ADHD-related executive functions over a 6-month period using the Brown Attention-Deficit Disorder Scale (BADDS) for Adults, a normed, 40-item, self-report scale in a randomized, double-blind, placebo-controlled clinical trial. METHOD In a randomized, double-blind clinical trial, adults with ADHD received(More)
Although the Wechsler Full Scale IQ (FSIQ) is a common component of most neuropsychological evaluations, there are many clinical situations where the complete administration of this battery is precluded by various constraints, including limitations of time and patient compliance. These constraints are particularly true for dementia evaluations involving(More)
OBJECTIVE Multivariate base rates allow for the simultaneous statistical interpretation of multiple test scores, quantifying the normal frequency of low scores on a test battery. This study provides multivariate base rates for the Delis-Kaplan Executive Function System (D-KEFS). METHOD The D-KEFS consists of 9 tests with 16 Total Achievement scores (i.e.(More)
The psychometric criterion of mild cognitive impairment (MCI) generally involves having an unusually low score on memory testing (i.e., -1.5 SDs). However, healthy older adults can obtain low scores, particularly when multiple memory measures are administered. In turn, there is a substantial risk of psychometrically misclassifying MCI in healthy older(More)
OBJECTIVE Validation of the Adult ADHD Investigator Symptom Rating Scale (AISRS) that measures aspects of ADHD in adults. METHOD Psychometric properties of the AISRS total and AISRS subscales are analyzed and compared to the Conners' Adult Attention-Deficit/Hyperactivity Disorder Rating Scale-Investigator Rated: Screening Version (CAARS-Inv:SV) and the(More)
