Examining the validity of eye tracking during the computerized Wisconsin card sorting test in a sample of stroke patients and healthy controls.

Introduction: Each year, approximately 50,000 Canadians, one million Americans, and millions of people worldwide are hospitalized for stroke. Cognitive impairment is common after experiencing a stroke and is known to affect functioning on daily tasks. While neuropsychological assessments are often employed to assess cognitive abilities and make inferences about functional capabilities, there is growing interest in integrating contemporary technologies to augment assessment.

A systematic review of the effects of cannabis on cognition in people with multiple sclerosis.

Background: Multiple sclerosis (MS) is a chronic demyelinating disease which leads to sensory, motor, autonomic, and cognitive symptoms. Cannabis is a common way for persons with MS (pwMS) to seek symptomatic therapy. Given the capacity for both cannabis and MS to cause cognitive impairment, it is important to determine whether there is any negative impact when the two co-occur.

A psychometric examination of the PAI-SF in persons with recent stroke.

The present study evaluated the psychometric properties of the Personality Assessment Inventory-Short Form (PAI-SF) for use with patients with recent stroke. Study participants ( = 170) were inpatients in a tertiary hospital in Western Canada admitted to a rehabilitation department who completed a neuropsychological evaluation as part of their care. All participants completed the full-form of the PAI (344 items) and both full- and short-form (160 items) versions were scored from the same protocol.

Does Happiness Improve Health? Evidence From a Randomized Controlled Trial.

Happier people are healthier, but does becoming happier lead to better health? In the current study, we deployed a comprehensive, 3-month positive psychological intervention as an experimental tool to examine the effects of increasing subjective well-being on physical health in a nonclinical population. In a 6-month randomized controlled trial with 155 community adults, we found effects of treatment on self-reported physical health-the number of days in the previous month that participants felt healthy or sick, as assessed by questions from the Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System Questionnaire. In a subsample of 100 participants, we also found evidence that improvements in subjective well-being over the course of the program predicted subsequent decreases in the number of sick days.

ENHANCE: Evidence for the efficacy of a comprehensive intervention program to promote subjective well-being.

Building from the growing empirical science of happiness, or subjective well-being (SWB), we have developed a 12-week comprehensive intervention program-Enduring Happiness and Continued Self-Enhancement (ENHANCE)-to increase SWB and enable a thorough examination of the mechanistic processes of program content and administrative structure for SWB change over time. In a randomized controlled trial, participants (N = 155; 55 using the in-person format, 100 online format) were randomly assigned to participate in ENHANCE or to a waitlist control condition. All participants completed assessments of SWB, including non-self-report measures, and process variables at baseline, posttest, and follow-up (3 months).

Allocentric Versus Egocentric Neglect in Stroke Patients: A Pilot Study Investigating the Assessment of Neglect Subtypes and Their Impacts on Functional Outcome Using Eye Tracking.

Objective: Few studies have investigated the assessment and functional impact of egocentric and allocentric neglect among stroke patients. This pilot study aimed to determine (1) whether allocentric and egocentric neglect could be dissociated among a sample of stroke patients using eye tracking; (2) the specific patterns of attention associated with each subtype; and (3) the nature of the relationship between neglect subtype and functional outcome.

Method: Twenty acute stroke patients were administered neuropsychological assessment batteries, a pencil-and-paper Apples Test to measure neglect subtype, and an adaptation of the Apples Test with an eye tracking measure.

Psychological disturbance and cognitive functioning in TBI patients.

The current study examined psychopathology and neuropsychological test performance in a traumatic brain injury (TBI) patient sample. Previous research has found that the Minnesota Multiphasic Personality Inventory - Second Edition (MMPI-2) indices of psychological disturbance were related to specific neuropsychological tests of attention and memory. Furthermore, higher scores on clinical scale 2 (Depression) and higher scores on the content scales of Fears and Bizarre Mentation of the MMPI-2 were related to poorer performance in, most notably, Attention and List Learning factors.

Assessing the predictive value of a neuropsychological model on concurrent function in acute stroke recovery and rehabilitation.

Few studies have examined the relationship between cognition and function for acute stroke inpatients utilizing comprehensive methods. This study aimed to assess the relationship of a neuropsychological model, above and beyond a baseline model, with concurrent functional status across multiple domains in the early weeks of stroke recovery and rehabilitation. Seventy-four acute stroke patients were administered a comprehensive neuropsychological assessment.

Comparison of the Buschke Selective Reminding Test and the California Verbal Learning Test - Second Edition in a heterogeneous sample of people with traumatic brain injury.

This study examined score and classification differences between the Buschke Selective Reminding Test (SRT) and the California Verbal Learning Test - Second Edition (CVLT-II) in a TBI sample. Seventy-nine participants with traumatic brain injury (TBI) were included and were comprised of 49 mild TBI, 11 moderate TBI, and 14 severe TBI. The majority of participants with mild TBI were involved in litigation.

Comparison of the Buschke Selective Reminding Test and the California Verbal Learning Test-Second Edition in a stroke population.

There are many tests of learning and memory; however, not all yield analogous results and thus are not interchangeable. This study examined the relationship between the California Verbal Learning Test-Second Edition (CVLT-II) and the Buschke Selective Reminding Test (SRT) in a stroke population. Data from stroke inpatients (N = 102) referred for rehabilitation were collected from medical records.
