The current study aimed to clarify the relationship among the constructs involved in neuropsychological assessment, including cognitive performance, symptom self-report, performance validity, and symptom validity. Participants consisted of 120 consecutively evaluated individuals from a veteran's hospital with mixed referral sources. Measures included the Wechsler Adult Intelligence Scale-Fourth Edition Full ...

A number of performance validity tests (PVTs) are used to assess memory complaints associated with traumatic brain injury (TBI); however, few studies examine the concordance and predictive accuracy of multiple PVTs, specifically in the context of combined models in known-group designs. The present study compared five widely used PVTs: ...

PURPOSE/OBJECTIVE: To examine resilience in the context of adjustment to traumatic brain injury (TBI), including the relative roles of demographic and theoretically related constructs such as coping, social support, and positive affectivity on resilience within the first 5 years postinjury. RESEARCH METHOD/DESIGN: This was a cross-sectional, observational study of ...

OBJECTIVE: The present study examined the incremental utility of item-level response time (RT) variables on a traditional performance validity test in distinguishing adults with verified TBI from adults coached to feign neurocognitive impairment. METHOD: Participants were 45 adults with moderate to severe TBI, 45 healthy adults coached to feign ...

PURPOSE: Having independent versions of the PROMIS® scales (for Pediatric and Adults) is problematic as scores cannot be evaluated longitudinally as individuals move from childhood into adulthood. The primary aim of this research project is to use item response theory (IRT) to develop a transitional scoring link (or "crosswalk") ...

Ethnically diverse examinees tend to perform lower on neuropsychological tests. The practice of adjusting normative comparisons for the education level and/or race to prevent overpathologizing low scores is problematic. Education quality, as measured by reading recognition, appears to be a more accurate benchmark for premorbid functioning in certain populations. ...

To provide important reliability and validity data to support the use of the Patient-Reported Outcomes Measurement Information System (PROMIS) mental health measures in caregivers of civilians or service members/veterans (SMVs) with traumatic brain injury (TBI).

OBJECTIVE: To examine how health self-efficacy and cognitive impairment severity relate to functional independence after acquired brain injury (ABI). DESIGN: Observational. SETTING: Outpatient rehabilitation hospital. PARTICIPANTS: Seventy-five adults with predominately stroke or traumatic brain injury who were beginning a course of occupational therapy. MAIN MEASURES: Health self-efficacy was assessed ...

To develop a new measurement system, the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL), that can evaluate both general and caregiving-specific aspects of health-related quality of life (HRQOL) in caregivers of persons with traumatic brain injury (TBI).

OBJECTIVE: To (1) identify groups of persons with traumatic brain injury (TBI) who differ on 12 dimensions of cognitive function: cognitive, emotional, and physical symptoms; personal strengths; physical functioning; environmental supports; and performance validity; and (2) describe patterns of differences among the groups on these dimensions and on participation ...

To develop new patient-reported outcome (PRO) measures to better understand feelings of loss in caregivers of individuals with traumatic brain injury (TBI)

To design a new measure of caregiver-specific anxiety for use in caregivers of individuals with traumatic brain injury (TBI), the Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Caregiver-Specific Anxiety item bank.

OBJECTIVE: To assess differential item functioning and observed mean differences across two modes of administration for PROMIS® measure scores in a sample of adults with traumatic injury. METHOD: Items from 7 PROMIS® adult measures (v1.0 Physical Function, Fatigue, Pain Interference, Anger, Anxiety, and Depression and v2.0 Social Health-Emotional Support) ...

To develop a new measure of caregiver strain for use in caregivers of individuals with traumatic brain injury (TBI), Traumatic Brain Injury Caregiver Quality of Life (TBI-CareQOL) Caregiver Strain.

Few studies address the course of recovery from prolonged disorders of consciousness (DOC) after severe traumatic brain injury (TBI). This study examined acute and long-term outcomes of persons with DOC admitted to acute inpatient rehabilitation within the National Institute on Disability and Rehabilitation Research (NIDRR) TBI Model Systems Programs ...

OBJECTIVE: This study explored the utility of combining data from measures of performance validity and symptom validity among Veterans undergoing neuropsychological evaluation for mild traumatic brain injury (mTBI). BACKGROUND: Persistent cognitive impairments following mTBI are often reported by returning combat veterans. However, objectively-measured cognitive deficits are not common among ...

This study examined embedded performance validity indicators (PVI) based on the number of impaired scores in an evaluation and the overall test battery mean (OTBM). Adult participants (N = 175) reporting traumatic brain injury were grouped using eight PVI. Participants who passed all PVI (n = 67) demonstrated fewer impaired scores and higher ...
