The Impact of Self-Efficacy and Health Locus of Control on Performance Validity Testing.

Objective: Recent research has examined potential influences to performance validity testing beyond intentional feigning. The current study sought to examine the hypothesized relationships of two psychological constructs (self-efficacy and health locus of control) with performance validity testing (PVT).

Method: Retrospective review of 158 mild traumatic brain injury (mTBI) cases referred to an Army outpatient clinic for neuropsychological evaluation.

Clinical utility of the mBIAS and NSI validity-10 to detect symptom over-reporting following mild TBI: A multicenter investigation with military service members.

Self-report measures are commonly relied upon in military healthcare environments to assess service members following a mild traumatic brain injury (mTBI). However, such instruments are susceptible to over-reporting and rarely include validity scales. This study evaluated the utility of the mild Brain Injury Atypical Symptoms scale (mBIAS) and the Neurobehavioral Symptom Inventory Validity-10 scale to detect symptom over-reporting.

Clinical utility of the memory complaints inventory to detect invalid test performance.

Objective: This investigation was designed to examine the classification statistics of Memory Complaints Inventory (MCI) scores relative to the Medical Symptom Validity Test (MSVT) and the Non-Verbal Medical Symptom Validity Test (NV-MSVT), as well as various validity scales on the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 Restructured Form(MMPI-2-RF).

Method: The sample consisted of 339 active duty service members with a history of concussion who completed performance validity tests (PVTs), symptom validity tests (SVTs), and the MCI.

Results: Those who failed the MSVT and NV-MSVT had significantly higher scores across all MCI scales.

Performance validity test and neuropsychological assessment battery screening module performances in an active-duty sample with a history of concussion.

The current retrospective investigation sought to replicate previous findings demonstrating the significant impact of performance validity test (PVT) performance and evaluation context on neuropsychological testing. We examined differences on performance validity testing between active-duty service members undergoing neurocognitive screening for concussion who were seen in a clinical context and those who were seen in a disability-seeking context, as well as the overall impact of PVT performance on a neurocognitive screening battery. Overall, 38.

Emotional distress affects attention and concentration: the difference between mountains and valleys.

The current study tests the hypothesis that the "mountains and valleys pattern" (MVP) observed within the Attention and Concentration domain of the Meyers Neuropsychological Battery reflects the interference of emotional distress/anxiety on the patient's cognitive test performance. First, the MVP was objectively quantified using a formula that took into account both increased and decreased scores, rather than canceling them out through averaging. Using a total sample of 787 subjects, the Minnesota Multiphasic Personality Inventory-Second Edition Restructured Form (MMPI-2-RF) profile scores of cases with and without this pattern were then compared using an extensive database followed by a smaller, matched-groups design.
