Race differences in a sample of vocational rehabilitation clients with traumatic brain injury.

Objective: To evaluate race differences in demographics, injury severity, and vocational outcomes for persons with TBI.

Participants: Seventy-five individuals with TBI (13 African American, 62 Caucasian) who requested services from the Missouri Division of Vocational Rehabilitation (VR) over a 2-year period.

Measures: Demographics (i.

The neurobehavioural rating scale-revised: sensitivity and validity in closed head injury assessment.

Objectives: To investigate the factor structure and psychometric properties of the neurobehavioural rating scale-revised (NRS-R) and to determine its usefulness in clinical trials.

Methods: A consecutive series of patients sustaining severe closed head injury were evacuated to one of 11 large regional North American trauma centres and entered into a randomised, phase III, multicentre clinical trial investigating the therapeutic use of moderate hypothermia. Acute care personnel were blinded to outcome and outcome personnel were blinded to treatment condition.

Factor analysis of an outcome interview for use in clinical trials of traumatically brain-injured patients: a preliminary study.

Objective: To study the factor structure, internal consistency, concurrent validity, and sensitivity to detect change in patient report of problems of a structured interview in relationship with accepted outcome measures.

Design: Outcome status of patients with severe traumatic brain injury participating in a randomized, phase III, multicenter clinical trial was assessed at 6 mo postinjury using the Glasgow Outcome Scale, the Disability Rating Scale, and the Severe Traumatic Brain Injury Outcome Interview.

Results: Exploratory factor analysis of the Severe Traumatic Brain Injury Outcome Interview produced a meaningful five-factor model: (1) activities of daily living; (2) cognitive; (3) affective; (4) behavioral; and (5) instrumental activities of daily living.

Neurobehavioral effects of phenytoin and carbamazepine in patients recovering from brain trauma: a comparative study.

Objective: To compare the effects of prophylactic anticonvulsant use of phenytoin and carbamazepine on the cognitive and emotional status of the patient after brain injury.

Design: Double-blind, placebo-controlled study with assessments before and after withdrawal from drug treatment.

Setting: Patients had been initially treated by neurosurgeons at a university hospital and were followed up during the study on an outpatient basis.

Factor analysis of the WMS-R and the WAIS.

A principal components factor analysis of the Wechsler Memory Scale-Revised (WMS-R) and Wechsler Adult Intelligence Scale (WAIS) was performed on 133 patients referred for neuropsychological assessment al a university medical center. Six factors were selected according to the Scree test, percentage of variance extracted, and the meaningfulness of the factors. The factors were labelled as follows: Perceptual Organization, Verbal Comprehension, Attention/Concentration, Complex Verbal Memory, Verbal Paired-Associate Memory, and Visual Paired Associate Memory.
