Abstract: There is an increasing need to develop new neuropsychometric tools sensitive enough to detect subtle declines in cognitive performance during normal aging, as well as to distinguish between normal aging and the earliest stages of dementia. In this study, we report our findings regarding a new confrontational naming test, the Memory for Names test. We conducted evaluations utilizing a cohort of 234 elderly participants who comprised a spectrum of cognitive function ranging from normal for age (Uniform Data Set Overall Appraisal = 2, Clinical Dementia Rating = 0) to demented (Clinical Dementia Rating = 1–2, Mini Mental Status Examination Total …Score <25). The Memory for Names test was found to measure the same cognitive construct as the Boston Naming Test. In conclusion, the Memory for Names test is a reliable and valid measure of age-related cognitive function that can discriminate between normal aging and mild cognitive impairment, and between mild cognitive impairment and dementia.

Abstract: Dementia is a chronic condition in the elderly and depression is often a concurrent symptom. As populations continue to age, accessible and useful tools to screen for cognitive function and its associated symptoms in elderly populations are needed. The aim of this study was to test the reliability and validity of a new internet-based assessment battery for screening mood and cognitive function in an elderly population. Specifically, the Helping Hand Technology (HHT) assessments for depression (HHT-D) and global cognitive function (HHT-G) were evaluated in a sample of 57 elderly participants (22 male, 35 female) aged 59–85 years. The study sample …was categorized into three groups: 1) dementia (n  = 8; Mini-Mental State Exam (MMSE) score 10–24), 2) mild cognitive impairment (n  = 24; MMSE score 25–28), and 3) control (n  = 25; MMSE score 29–30). Test-retest reliability (Pearson correlation coefficient, r) and internal consistency reliability (Cronbach’s alpha, α ) of the HHT-D and HHT-G were assessed. Validity of the HHT-D and HHT-G was tested via comparison (Pearson r) to commonly used pencil-and-paper based assessments: HHT-D versus the Geriatric Depression Scale (GDS) and HHT-G versus the MMSE. Good test-retest (r = 0.80; p  < 0.0001) and acceptable internal consistency reliability (α = 0.73) of the HHT-D were established. Moderate support for the validity of the HHT-D was obtained (r  = 0.60 between the HHT-D and GDS; p  < 0.0001). Results indicated good test-retest (r  = 0.87; p  < 0.0001) and acceptable internal consistency reliability (α = 0.70) of the HHT-G. Validity of the HHT-G was supported (r  = 0.71 between the HHT-G and MMSE; p  < 0.0001). In summary, the HHT-D and HHT-G were found to be reliable and valid computerized assessments to screen for depression and cognitive status, respectively, in an elderly sample. Show more

Abstract: BACKGROUND: Active workstation alternatives (e.g., treadmill desks and pedal desks) have the potential to elevate workplace energy expenditure by replacing occupational sedentary behavior with opportunities to generate low-intensity non-exercise physical activity, but only to the extent that workers find them acceptable and congruent with their primary working tasks and therefore can frequently use them for extended periods of time. OBJECTIVE: To assess workers’ acceptability of the Pennington Pedal Desk™. METHODS: Full-time sedentary workers (N = 42; 76% female; mean+SD age 39.6±11.3 years; BMI 25.7±5.4 kg/m2 ) used the pedal desk for 15 minutes while they: 1) searched the internet, 2) …composed an email, and 3) completed acceptability ratings using an online Likert scale anchored from 1/strongly disagree to 5/strongly agree. Garmin Vector power meter pedals and EDGE 510 GPS bike computer (Garmin ® , USA) continuously captured revolutions per minute (RPM) and power. RESULTS: Participants indicated that they would use the pedal desk for 4 (median) hours per work day and 97.6% of participants were somewhat or completely confident that they could type proficiently while using the pedal desk. Participants pedaled at 54.8±11.2 RPM and 23.1±8.6 watts (mean+SD). CONCLUSIONS: Participants rated the Pennington Pedal Desk™ workstation positively and indicated potential for extended daily use.
