Logical memory, visual reproduction, and verbal paired associates are effective embedded validity indicators in patients with traumatic brain injury.

Objective: This study was design to evaluate the potential of the recognition trials for the Logical Memory (LM), Visual Reproduction (VR), and Verbal Paired Associates (VPA) subtests of the Wechsler Memory Scales-Fourth Edition (WMS-IV) to serve as embedded performance validity tests (PVTs).

Method: The classification accuracy of the three WMS-IV subtests was computed against three different criterion PVTs in a sample of 103 adults with traumatic brain injury (TBI).

Results: The optimal cutoffs (LM ≤ 20, VR ≤ 3, VPA ≤ 36) produced good combinations of sensitivity (.

Critical item (CR) analysis expands the classification accuracy of performance validity tests based on the forced choice paradigm-Replicating previously introduced CR cutoffs within the Word Choice Test.

Objective: This study was designed to replicate previous research on critical item analysis within the Word Choice Test (WCT).

Method: Archival data were collected from a mixed clinical sample of 119 consecutively referred adults ( = 51.7, = 14.

Self-rated executive dysfunction in adults with epilepsy and effects of a cognitive-behavioral intervention (HOBSCOTCH).

Rationale: Cognitive problems are common in adults with epilepsy and significantly affect their quality of life. HOBSCOTCH (HOme Based Self-management and COgnitive Training CHanges lives) was developed to teach problem-solving and compensatory memory strategies to these individuals. This study examined whether HOBSCOTCH is associated with improvement in specific aspects of subjective executive functions.

Differentiating epilepsy from psychogenic nonepileptic seizures using neuropsychological test data.

Objective: Differentiating epileptic seizures (ES) from psychogenic nonepileptic seizures (PNES) represents a challenging differential diagnosis with important treatment implications. This study was designed to explore the utility of neuropsychological test scores in differentiating ES from PNES.

Method: Psychometric data from 72 patients with ES and 33 patients with PNES were compared on various tests of cognitive ability and performance validity.

Patient safety considerations in the rehabilitation of the individual with cognitive impairment.

Deficits in cognitive functioning are associated with many safety concerns, including difficulties performing activities of daily living, medication errors, motor vehicle accidents, impaired awareness of deficits, decision-making capacity, falls, and travel away from home. Preventing adverse safety outcomes is particularly relevant in rehabilitation patients. Integration of information and recommendations stemming from allied disciplines, such as rehabilitation medicine, physical therapy, occupational therapy, speech therapy, and neuropsychology, is the most effective way to limit poor outcomes.
