The Factor Structure of the Boston Diagnostic Aphasia Examination, Third Edition.

Objective: The Boston Diagnostic Aphasia Examination (BDAE) is one of the most commonly used aphasia batteries. The newest edition has undergone significant revisions since its original publication in 1972, but existing evidence for its validity is lacking. We examined the construct validity of BDAE-3 and identified the factor structure of this battery.

Predicting Cognitive Functioning, Activities of Daily Living, and Participation 6 Months after Mild to Moderate Stroke.

Objective: Predicting neurocognitive and functional outcomes in stroke is an important clinical task, especially in rehabilitation settings. We assessed acute predictors of cognitive and functional outcomes 6 months after mild to moderate stroke.

Methods: We conducted a retrospective analysis of acute clinical data and 6-month follow-up telephone interviews for 498 mild to moderate stroke patients.

Utility of Serum Biomarkers in the Diagnosis and Stratification of Mild Traumatic Brain Injury.

Objective: The objective was to compare test characteristics of a single serum concentration of glial fibrillary acidic protein (GFAP), S-100β, and ubiquitin carboxyl terminal hydrolase L1 (UCH-L1), obtained within 6 hours of head injury, to diagnose mild traumatic brain injury (mTBI) in head-injured subjects.

Methods: Adults aged 18 to 80 years who presented to one of seven EDs with a blunt closed head injury underwent head CT within 4 hours of injury and had blood drawn for biomarker analysis within 6 hours of injury were eligible. Subjects were considered to have mTBI if they had an initial Glasgow Coma Scale (GCS) > 13 and met one or more of the following criteria: loss of consciousness (LOC), posttraumatic amnesia, or confusion.

Exploratory factor analysis of the reintegration to normal living index in a stroke population.

Background: The reintegration to normal living index (RNLI) is a global assessment of patient quality of life often utilized in stroke populations. Previous studies in various general disability samples have consistently reported a two-factor solution for the RNLI. Despite its common use with stroke patients, the RNLI has not been psychometrically evaluated in an exclusively stroke sample.
