Article Synopsis
- - This study explored how the severity of processing speed impairment affects performance on the Rey 15-Item Test (RFIT) and its recognition variant, revealing that those with intact processing speed scored better than those with reduced or impaired speeds.
- - Data from 285 neuropsychological assessments were analyzed, using various standardized tests to measure processing speed and other cognitive functions, with results showing significant predictive power from both verbal/visual memory and processing speed.
- - While the RFIT tests showed good classification accuracy for individuals with intact processing speed, their effectiveness dropped significantly for those with impaired speeds, indicating that the RFIT may not be suitable for evaluating individuals with greater processing speed deficits.
Article Synopsis
- * The study included 129 adult outpatients and found that combining MIL and MCT-AI improved the detection of invalid performance, increasing sensitivity from 10-31% to 70% while keeping specificity above 90%.
- * Results indicate that failing either test is linked to lower cognitive scores, and failing both leads to significantly lower scores, supporting the idea that using multiple PVTs in assessments is beneficial.
Objective: The Making Change Test (MCT) is a brief, digitized freestanding performance validity test (PVT) designed for tele-neuropsychology (TeleNP). The objective of this study was to report the initial validation of the MCT in a mixed neuropsychiatric sample referred for neuropsychological evaluation using a known-groups design.
Method: The sample consisted of 136 adult outpatients who underwent a neuropsychological evaluation.
The Survey for Memory, Attention, and Reaction Time (SMART) was recently introduced as a brief (<5 min), self-administered, web-based measure of cognitive performance in older adults. The purpose of this study was threefold: (1) to develop preliminary norms on the SMART; (2) to examine the relationship between demographic variables (i.e.

Remote, technology-based tools have shown recent promise in assessing changes in older adults' daily activities and mood, which may serve as indicators of underlying health-related changes (e.g.

Physical activity (PA) has been linked to cognitive functioning and mental health in older adulthood. Multiple subjective (i.e.
View Article and Find Full Text PDFBackground: As researchers incorporate in-home technologies to identify and track changes in older adults' cognitive and daily functioning that could lead to early interventions, the attitudes of older adults across the continuum from normal cognitive aging to mild cognitive impairment (MCI) must be assessed to ensure technology adoption and adherence in each unique group.
Objective: This exploratory pilot study incorporated both quantitative and qualitative approaches to examine mild cognitive impairment (MCI) and cognitively intact older adults' attitudes (i.e.
Introduction: Brief, Web-based, and self-administered cognitive assessments hold promise for early detection of cognitive decline in individuals at risk for dementia. The current study describes the design, implementation, and convergent validity of a fWeb-based cognitive assessment tool, the Survey for Memory, Attention, and Reaction Time (SMART), for older adults.
Methods: A community-dwelling sample of older adults (n = 69) was included, classified as cognitively intact (n = 44) or diagnosed with mild cognitive impairment (MCI, n = 25).

Introduction: Medication-taking is a routine instrumental activity of daily living affected by mild cognitive impairment (MCI) but difficult to measure with clinical tools. This prospective longitudinal study examined in-home medication-taking and transition from normative aging to MCI.
Methods: Daily, weekly, and monthly medication-taking metrics derived from an instrumented pillbox were examined in 64 healthy cognitively intact older adults (Mage=85.
Background: Aging military veterans are an important and growing population who are at an elevated risk for developing mild cognitive impairment (MCI) and Alzheimer dementia, which emerge insidiously and progress gradually. Traditional clinic-based assessments are administered infrequently, making these visits less ideal to capture the earliest signals of cognitive and daily functioning decline in older adults.
Objective: This study aimed to evaluate the feasibility of a novel ecologically valid assessment approach that integrates passive in-home and mobile technologies to assess instrumental activities of daily living (IADLs) that are not well captured by clinic-based assessment methods in an aging military veteran sample.
