Performance on the Test of Memory Malingering (TOMM) was evaluated in a sample of 100 consecutively referred 6 to 16-year-old children with a wide range of clinical diagnoses. In the complete sample, 97 children met actuarially defined criteria for sufficient effort on the TOMM. Two children were correctly identified as providing suboptimal effort and only(More)
The California Verbal Learning Test (CVLT; Delis, Kramer, Kaplan, & Ober, 1987) data of 150 patients with traumatic brain injury (TBI) were evaluated to determine the latent underlying constructs as well as the possibility of performance subtypes with criterion validity. Confirmatory factor analysis of eight competing latent variable models suggested that a(More)
OBJECTIVE To investigate the usefulness of the Test of Memory Malingering (TOMM) and the California Verbal Learning Test-Second Edition (CVLT-II) in assessing invalid test performance after traumatic brain injury (TBI). DESIGN Consecutive 3-year series of rehabilitation referrals (n = 132). METHODS AND PROCEDURES Percentage of participants who failed(More)

The standardization data for the California Verbal Learning Test-Children's Version (CVLT-C) were used to evaluate statistically significant discrepancies between key quantitative variables of this instrument, as well as the base rate of specific discrepancies. The results indicated that apparently large discrepancies between the respective standard scores(More)
A group of 30 five- to eight-year-old hydrocephalic children was administered a comprehensive battery of neuropsychological tests. As a group, they displayed a pattern of lower PIQ than VIQ. Their performance was within the average range of many neuropsychological tests, but they performed poorly on some measures of complex visuospatial functioning. It is(More)
It has been suggested that a ratio score of part B to part A of the Trail Making Test (TMT) may have clinical utility as a measure of cognitive efficiency and/or dissimulation. We investigated the clinical utility of the TMT B/A ratio score in the evaluation of patients with traumatic brain injury. Part B of the TMT demonstrated a statistically significant(More)
The performance of 40 children with complicated mild to severe traumatic brain injury on the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; Wechsler, 2003) was compared with that of 40 demographically matched healthy controls. Of the four WISC-IV factor index scores, only Processing Speed yielded a statistically significant group(More)
This study investigated the relationship between child functional independence, family dynamics, psychosocial factors, and level of distress in parents of children with congenital disabilities. The Vineland Adaptive Behavior Scales, the Family Assessment Device (FAD), and the Brief Symptom Inventory (BSI) were administered to 60 parents of children with(More)
We report the case of a patient with selective topographic orientation deficits in both familiar and novel environments after bilateral medial occipital infarctions. Extensive neuropsychological assessment revealed intact functioning in all other cognitive domains. The findings are interpreted in terms of a dissociation between the retrosplenial posterior(More)
The California Verbal Learning Test-Second Edition (CVLT-II) was performed by 200 participants, divided into moderate-severe traumatic brain injury (n=43), mild traumatic brain injury (n=57) and demographically matched control (n=100) groups. Participants with complicating premorbid histories or who scored below 15/16 on the CVLT-II forced choice(More)
