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, recording, and scoring tasks have not been syste...

The present study examined the factor structure of the Wechsler Intelligence Scale for Children– Fourth Edition, Spanish (WISC–IV Spanish, Wechsler, 2005a) with normative sample participants aged 6–16 years (N = 500) using confirmatory factor analytic techniques not reported in the WISC– IV Spanish Manual (Wechsler, 2005b).

The Vineland–II was designed to be an easily used, standardized measure of key domains of adaptive behavior–Communication, Daily Living Skills, and Socialization–that play a prominent role in the diagnosis of mental retardation and other developmental disabilities. The...

This study examined pre-surgical depressed mood as a predictor of post-surgical memory change in adults who underwent temporal lobe resections (TLRs; n = 211). Patients completed the Wechsler Memory Scale-III and Beck Depression Inventory-Second Edition (BDI-II) before and after TLR (left = 110, right = 101) and were divided into two groups (clinically elevated depressive symptoms or not depres...

WAIS-R Verbal-Performance IQ difference scores for Ward's (1990) seven subtest short form and the complete WAIS-R were examined in patients with lateralized and diffuse lesions. For both versions, the expected Performance > Verbal pattern was observed in the right hemisphere lesion group, while no summary score differences were seen in the left hemisphere group. Verbal-Performance IQ discrepanc...

The present study examined the incremental validity of Wechsler Adult Intelligence Scale-4th Edition (WAIS-IV; Wechsler, 2008a) factor index scores in predicting academic achievement on the Wechsler Individual Achievement Test-2nd Edition (WIAT-II; Psychological Corporation, 2002a) and on the Wechsler Individual Achievement Test-3rd Edition (WIAT-III; Wechsler, 2009a) beyond that predicted by t...

A previous study on the underlying structure of the Wechsler intelligence test (WISC-R; [Wechsler, D. (1974). Manual WISCR: Wechsler intelligence scale for children—Revised. New York: Psychological Corporation]), using smallest space analysis (SSA) [Guttman, L., and Levy, S. (1991). Two structural laws for intelligence tests. Intelligence, 15, 79–103] had indicated a threedimensional cylindrica...
