BASELINE DRIVING MILEAGE PREDICTS STATE-REPORTED CRASHES ACROSS 5 YEARS

Abstract Although annual driving mileage has frequently been examined as a predictor of crashes among older adults, most research used cross-sectional design and relied on self-reported crash data. This study used multivariate regression to examine the number of state reported at-fault crashes between groups of low (14,000km) self-reported annual distance over five years. Additionally, key factors of interest including age, gender, and population density were examined as predictors. The sample included 519 healthy older adults aged 65-90 (M=73.17, SD=5.56) across five sites in the United States. 12% of participants experienced a crash across five years, and among those who crashed, the majority (87%) experienced one crash (range 0-3 crashes). After controlling for age, gender and testing site, people in the high annual mileage group had a greater number of crashes compared to the low mileage group (β=.14, t(513)=2.37, p=.02). There was not a significant difference in number of prospective crashes between the low and medium group. Also, people who drove in sites with low population density had more crashes than those who in high population density sites (β=.10, t(513)=2.24, p=.03). Higher age was associated with a greater number of prospective crashes (β=.01, t(513)=3.67, p =.002); however, gender was not a significant predictor of crashes. Our results highlight the importance of examining prospective crashes over time, and taking mileage and population density into consideration. Future research should examine trajectories of driving exposure in relation to prospective crashes using multilevel modeling.

This study reports the findings of an anonymous web-based survey to test differences in symptom presentation (depression, anxiety, posttraumatic stress disorder [PTSD]) among women who experienced different types of sexual trauma (forcible, pressured, sex stress). The study used a descriptive cross-sectional design with an online convenience sample of 243 adult females living primarily in the United States. The findings revealed that there was a statistically significant difference among type of sexual trauma groups for depression (p = .013) and PTSD (p = .044) but not for anxiety (p = .183). Post hoc analysis of the overall difference in depression revealed that the multiple rape type group (p = .010) and the forcible sex group (p = .016) had higher levels of depression.

AbstractChanges in muscle stiffness have been reported with sarcopenia. Sonoelastography is an accessible and non-radiating imaging technique allowing quantification of elastic properties of tissue. We performed a systematic review of the literature to investigate whether sonoelastography can be a reliable method to assess sarcopenia in older patients. We searched Medline, Google Scholar, Scopus, SpringerLink and Science direct from January 1, 1990 to April 1, 2020. Three independent review authors assessed trial eligibility, extracted the data, and assessed risk of bias. We intended to learn which types of elastography have been tested, if such measures are repeatable, and if they have been compared to the currently accepted diagnostic method. Ten studies met the inclusion criteria. Most followed a cross-sectional design with young and older adult subgroups. The gastrocnemius, rectus femoris, and vastus intermedius appeared most frequently. Nine of the included studies used shear wave elastography and one-strain elastography. The passive elastic constant was significantly greater in sarcopenic versus healthy subjects after passive stretching (124.98 ± 60.82 vs. 46.35 ± 15.85, P = 0.004). However, even in non-sarcopenic patients, the age of the patient was responsible for about 45.5 % of the variance in SWV. Among ten included articles, four reported higher stiffness in the muscles of older adults, two reported lower stiffness, and four found no significant difference. Due to the substantial heterogenicity of actual data, we could not make any conclusions about the potential usefulness of elastography to assess sarcopenia. Further studies are needed, including a larger sample of older patients and using a standardized and reproducible protocol.

Religiosity And Depression

Background: A mediation model was proposed to explain how religiosity, religious coping, and fear of coronavirus disease 2019 (COVID-19) explained anxiety and depression among older adults. Methods: With the use of a cross-sectional design, the Integrated Health System was used to randomly invite 1000 older adults residing in Qazvin to participate in an online survey. Within the period of November 2020 to January 2021, 696 older Iranian adults (mean age=69.56years; 57.9% women) agreed to participate in the study and reported demographic information as well as measures of religiosity, fear of COVID-19, religious coping, anxiety, and depression. Results: Religiosity had direct effects on depression (B [SE]=-0.087 [0.037]; P=0.023) but not anxiety (B [SE]=-0.063 [0.036]; P=0.072). Moreover, both fear of COVID-19 and religious coping significantly mediated the association between religiosity and anxiety (B [SE]=-0.360[0.035]; p=0.002) and that between religiosity and depression (B [SE]=-0.365 [0.034];P=0.002). Conclusion: During the tough time of COVID-19 pandemic, religiosity and religious coping were protectors for older adults in developing good mental. Therefore, future research is needed to examine education programs that are effective for older adults to obtain correct knowledge concerning COVID-19, including the protective COVID-19 infection behaviors. Therefore, older adults may reduce their fear via their enhanced correct knowledge concerning COVID-19.

The Relationship

Abstract he positive association between discrimination and depression is well-supported throughout the literature. Previous evidence exploring potential mechanisms suggest discrimination is associated with depression via changes in social cognition. The goal of the current study was to investigate whether optimism explained the relationship between discrimination and depressive symptoms in mid-to-late life. Furthermore, the study assessed whether this mediated relationship was moderated by race or sex. This study included cross-sectional and longitudinal secondary data analysis of 2453 middle-aged and older adults (M age=68.30,SD=8.93) from the Midlife in the United States study. Discrimination was measured using an 11-item count of the number of discriminatory events experienced. Optimism was measured using the 6-item Life Orientation Test. Depressive symptoms were assessed using a 7-item count of the number of symptoms experienced. Optimism mediated the relationship between discrimination and depressive symptoms cross-sectionally, 95% CI:[.012, .034], and longitudinally, 95% CI:[.008, .024]. There was no evidence of moderated mediation; however, sex did moderate the direct relationship between discrimination and depressive symptoms cross-sectionally, b=.10, 95% CI:[.001, .194], and longitudinally, b=.03, 95% CI:[.01, .05]. The current study extends the literature by providing cross-sectional and longitudinal support for optimism as a mechanism through which discrimination leads to depressive symptoms in older adults. Evidence also suggests that women experience greater depressive symptoms than men in response to discrimination. Future research may wish to examine the developmental course of observed relationships and the impact of multiple marginalized identities on these relationships.

Evidence Based Treatments

The recent increase in the aging population, specifically in the United States, has raised concerns regarding treatment for mental illness among older adults. Late-life depression (LLD) is a complex condition that has become widespread among the aging population. Despite the availability of behavioral interventions and psychotherapies, few depressed older adults actually receive treatment. In this paper we review the research on refining treatments for LLD. We first identify evidence-based treatments (EBTs) for LLD and the problems associated with efficacy and dissemination, then review approaches to conceptualizing mental illness, specifically concepts related to brain plasticity and the Research Domain Criteria (RDoc). Finally, we introduce ENGAGE as a streamlined treatment for LLD and discuss implications for future research.

Abstract. Background: Given challenges that exceed the normal developmental requirements of adolescence, deaf and hard-of-hearing (DHH) youth are believed to be at elevated risk for engaging in suicide-related behavior (SRB). Unfortunately, little is known about the mechanisms that put these youth potentially at risk. Aims: To determine whether peer relationship difficulties are related to increased risk of SRB in DHH youth. Method: Student records (n = 74) were retrieved from an accredited educational center for deaf and blind students in the United States. Results: Peer relationship difficulties were found to be significantly associated with engagement in SRB but not when accounting for depressive symptomatology. Limitations: The restricted sample limits generalizability. Conclusions regarding risk causation cannot be made due to the cross-sectional nature of the study. Conclusion: These results suggest the need for future research that examines the mechanisms of the relationship between peer relationship difficulties, depression, and suicide risk in DHH youth and potential preventive interventions to ameliorate the risks for these at-risk youth.

Abstract Social engagement may confer cognitive benefits in older adulthood, but studies have typically been restricted to largely non-Hispanic White (NHW) samples. Levels of social engagement vary across race such that NHW report larger social networks, more frequent participation in social activities, and greater social support than non-Hispanic Blacks (NHB). Associations between social engagement and cognition may also vary by race, but research is sparse. The current cross-sectional study examined associations between different aspects of social engagement and episodic memory performance, as well as interactions between social engagement and race among NHB and NHW participants in the Michigan Cognitive Aging Project (N = 247; 48.4% NHB; age = 64.19 ± 2.92). Social engagement (network size, activities, support) was self-reported. Episodic memory was a z-score composite of immediate, delayed, and recognition trials of a list-learning task. Separate hierarchical linear regression models quantified interactions between race and each of the three social engagement variables on episodic memory, controlling for sociodemographics, depressive symptoms, and health conditions. Results showed a main effect of more frequent social activity on better episodic memory, as well as an interaction between race and social support indicating a significant positive association in NHB but not NHW. These preliminary findings suggest that participating in social activities may be equally beneficial for episodic memory across NHB and NHW older adults and that social support may be particularly beneficial for NHB. Future research is needed to determine the potential applications of these results in reducing cognitive inequalities through the development of culturally-relevant interventions.

Healthy Older Adults

ABSTRACT Objectives: The relationship between wisdom and fluid intelligence (Gf) is poorly understood, particularly in older adults. We empirically tested the magnitude of the correlation between wisdom and Gf to help determine the extent of overlap between these two constructs. Design: Cross-sectional study with preregistered hypotheses and well-powered analytic plan (https://osf.io/h3pjx). Setting: Memory and Aging Center at the University of California San Francisco, located in the USA. Participants: 141 healthy older adults (mean age = 76 years; 56% female). Measurements: Wisdom was quantified using a well-validated self-report-based scale (San Diego Wisdom Scale or SD-WISE). Gf was assessed via composite measures of processing speed (Gf-PS) and executive functioning (Gf-EF). The relationships of SD-WISE scores to Gf-PS and Gf-EF were tested in bivariate correlational analyses and multiple regression models adjusted for demographics (age, sex, and education). Exploratory analyses evaluated the relationships between SD-WISE and age, episodic memory performance, and dorsolateral and ventromedial prefrontal cortical volumes on magnetic resonance imaging. Results: Wisdom showed a small, positive association with Gf-EF (r = 0.181 [95% CI 0.016, 0.336], p = .031), which was reduced to nonsignificance upon controlling for demographics, and no association with Gf-PS (r = 0.019 [95% CI −0.179, 0.216], p = .854). Wisdom demonstrated a small, negative correlation with age (r = −0.197 [95% CI −0.351, −0.033], p = .019), but was not significantly related to episodic memory or prefrontal volumes. Conclusions: Our findings indicate that most of the variance in wisdom (>95%) is unaccounted for by Gf. The independence of wisdom from cognitive functions that reliably show age-associated declines suggests that it may hold unique potential to bolster decision-making, interpersonal functioning, and other everyday activities in older adults.

Introduction: Stroke incidence is reportedly increasing in younger adults. While increasing vascular risk factor prevalence has been suggested as a cause, the reasons for rising stroke incidence in the young are not clear. We explored several alternate explanations: trends in neurologically-focused emergency department (ED) visits, differential diagnostic classification of stroke and TIA over time, and changes in the use of advanced imaging in young and older adults. Methods: We performed a retrospective, serial, cross-sectional study on a nationally representative sample of all ED visits in the United States to quantify changes in patterns of neurologically-focused ED visits, stroke and TIA diagnoses, and rates of MRI utilization for young (18 – 44 years) and older (65+ years) adults over a 17-year period (1995 – 2000; 2005 – 2015) using National Hospital Ambulatory Medical Care Survey (NHAMCS) data. Results: In young adults, 0.4% (95% CI 0.3% – 0.5%) of neurologically-focused ED visits resulted in a primary diagnosis of stroke vs. 6.8% (95% CI 6.2% – 7.5%) for older adults. In both populations, the incidence of neurologically-focused ED visits has increased over time (+111/100,000 population/year, 95% CI +94 – +130 in the young vs. +70/100,000 population/year, 95% CI +34 – +108 in older adults). There was no evidence of differential classification of TIA to stroke over time (OR 1.001 per year, 95% CI 0.926 – 1.083 in the young; OR 1.003 per year, 95% CI 0.982 – 1.026 in older adults) and no evidence of disproportionate rise in MRI utilization for neurologically-focused ED visits in the young (OR 1.057 per year, 95% CI 1.028 – 1.086 in the young; OR 1.095 per year, 95% CI 1.066 – 1.125 in older adults). Conclusions: If the specificity of stroke diagnosis amongst ED visits is similar amongst young and older populations, then the combination of data observed here, including (1) a lower prior probability of stroke diagnoses in the young and (2) an increasing trend in neurologically-focused ED visits in both age groups, suggests that false positive diagnoses will increase over time, with a faster rise in the young compared to older adults. These data suggest a potential explanation that may contribute to higher stroke incidence in the young and merits further scrutiny.

Level Of Agreement

Objective – To survey middle managers’ beliefs regarding their participation in shared leadership and their libraries’ practices of shared leadership. Design – Cross-sectional survey. Setting – Twenty-two academic libraries within four-year public master’s level institutions in the Pacific Northwest of the United States. Subjects – A total of 115 middle managers were invited to participate; 77 completed the survey for a response rate of 66.9%. Methods – Selected middle managers were contacted by email a total of five times and were invited to complete a Web-based survey composed of three sections. The first section contained 10 statements for rating shared leadership within their own institutions, which they were asked to rate on an eight-point Likert scale from 1 (strongly agree) to 7 (strongly disagree), with 8 as an option for no opinion. The second section used the same scale to rate their levels of agreement with conceptual definitions of shared leadership from Jackson’s Framework. Jackson’s Framework consists of four components for ascertaining levels of shared leadership from both managerial and staff perspectives: accountability, equity, partnership and ownership. The third section invited subjects to provide their own definition of shared leadership. A three-part pretest served to validate the survey instrument. Mean scores were calculated for each statement. Main Results – In the first section, there was the highest overall level of agreement (1.52) with the statement “I am accountable for the decisions within the scope of my responsibility” followed by “I share information with the senior library administration” (1.71). There was the lowest overall level of agreement (3.65) with the statement that “Ideas presented at all levels of staff in the library are equally considered.” In the second section, respondents’ mean scores for Jackson’s definitions of four concepts of shared leadership were 2.62 for ownership, 2.68 for both partnership and equity, and 2.77 for accountability. In the third section, respondents most often linked their definitions of shared leadership with communication, learning and collaboration. Conclusion – Examining middle managers’ perceptions of shared leadership may help us understand organizational trends and capacity for leadership within libraries. Future research could examine shared leadership at levels below middle management as well as the relationship between accountability and shared leadership throughout the organization.
