Examining rural and racial disparities in the relationship between loneliness and social technology use among older adults. Frontiers in Public Health, 9(723925). DOI: 10.3389/fpubh.2021.723925
Overview: Findings of this study demonstrated that rurality, but not race, moderated the relationship between loneliness and social technology use among older adults. Additionally, those in rural environments tended to use social technology less than those in suburban environments.

Overview: This study examined the predictions of Strength and Vulnerability Integration theory, which posits that higher levels of chronic stress will attenuate favorable age gradients for multiple indices of well-being. The study found that older age is not significantly associated with well-being in conditions of high levels of chronic stress.

Overview: This study demonstrates the utility of examining within-person variability in a naturalistic driving dataset of 68 older drivers across two weeks. To our knowledge, this is the first study to use multilevel modeling to quantify variability in distracted driving behavior in a naturalistic dataset for older drivers.

Overview: This study examined satisfaction across life domains (condition of the home, city of residence, daily life/leisure, family life, current financial situation, total household income, health, and life as a whole) among Black adults. This study also examines the association between satisfaction in each domain and sociodemographic, personality, and mental/physical health measures. Results suggest that levels of life satisfaction vary across domains and that life satisfaction may serve as a source of resiliency for Black adults.

DOI: 10.1093/geronb/gby095
Overview: This study examined anxiety and satisfaction with computer-based and traditional paper-and-pencil based neuropsychological testing batteries among black colder adults. Results indicated that participants were more satisfied and less anxious using the computer batteries in comparison to the paper-and-pencil battery.
Phillips, C. B., *Freed, S. A., & Ross, L. A. (2019). Older adult lifespace varies by driving status and residential population density. Transportation Research Record, 2673(7), 586-595.doi: 10.1177/0361198119846092
Overview: This paper examined the relationship between baseline driving status and lifespace across five years and whether this relationship differed by residential status. Results indicated that non-drivers had smaller mean lifespace than drivers across five years, and rates of lifespace declines did not differ between drivers and non-drivers. Non-drivers at baseline residing in low population density areas had smaller lifespace than non-drivers in high population density areas. The findings suggest that residential context plays a role in older adults' travel behavior and choices.
*Sprague, B. N., Phillips, C. B., & Ross, L. A. (2017). Age-varying relationships between physical function and cognition in older adulthood. The Journals of Gerontology, Series B: Psychological Sciences & Social Sciences. doi: 10.1093/geronb/gbx126
Overview: This paper examined cross-sectional relationships between physical and cognitive function in older adults using a novel statistical technique called time-varying effects modeling (TVEM). Briana and her colleagues found that simple physical function was a stronger predictor of processing speed, memory, and reasoning for the oldest-old, and complex physical function generally was a stronger predictor for the young-old and oldest old. This demonstrates that age plays a critical role in how relationships between physical and cognitive function couple across the older adulthood continuum.

Overview: This paper examines teen drivers in the Senior and Adolescent Naturalistic Driving Study (SANDS). Worse self-reported executive function was associated with higher odds of self-reported problematic driving outcomes. However, there was no association between performance-based executive function meaasures and self-reported problematic driving outcomes. The authors discuss the application of research findings to potential screening tools for adolescent drivers.
Overview: The taxonomy, terms, and definitions constitute suggestions that, in the view of its sponsoring committee, will facilitate communication and promote best practice among a host of disciplines and professional organizations committed to safe, independent, and dignified options for seniors to remain mobile
within their communities. It is anticipated that this resource will be revised and updated as
needed to reflect the dynamic and evolving set of issues that confront practitioners in this area.

Overview: This paper examines teens and older drivers in the Senior and Adolescent Naturalistic Driving (SANDS) study. In teens, higher levels of openness and conscientiousness and lower levels of agreeableness were associated with greater frequency of texting and interacting with a phone while driving. In older adults, greater extraversion was associated with greater talking and interacting with a phone while driving. Results suggest that specific personality traits associated with distracted driving are different across age groups. Implications for targeted interventions are discussed.

Transportation Research Record, Transportation Research Board of the National Academies of Sciences, Engineering, and Medicine, 2584, 70-76. DOI:10.3141/2584-09.
Overview: Baseline cognitive function and visual acuity were positively related to changes in driving mobility across five years. Changes in general health and changes in physical function were positively associated with changes in driving mobility across five years. Patterns of associations varied depending on the specific physical function measure and mobility outcome. Results highlight the time-varying nature of the relationships between physical function and driving mobility.

Overview: This editorial reviews risk factors of driving safety in older adults, including cognitive and visual function, as well as interventions targeting these risk factors. Assessments of driving performed by physicians present issues with patient willingness to disclose driving difficulties and validity of physician assessment. Evidence-based screening of driving ability that is inexpensive, culturally appropriate, and easily administered by providers of different backgrounds is needed.

Overview: Factor analysis of executive function measures revealed two factors that require distinct executive processes. Greater cortical thickness in the Cingulo-Opercular Network predicts better performance on the Sustained Executive Control factor. Greater cortical thickness in the Frontoparietal Network predicts better performance on the Complex Attention Control factor. Results suggest that distinct brain networks predict different executive processes.

Overview: Findings suggest that there are not unique cognitive subtypes in HIV, but rather a subset of individuals who exhibit globally normal performance and those with below average performance. Older age and the related cardiovascular comorbidities of both aging and HIV medications may be key factors in explaining variability in neurocognitive functioning in this population.
