Factors Associated With Participation in Physical Leisure Activities in Taiwanese Community-Dwelling Older Adults.

This study was to identify factors at the intrapersonal, interpersonal, and community levels that relate to physical leisure participation in Taiwanese community-dwelling older adults and to examine their relative importance. We used a cross-sectional study with purposive sampling (N = 160). Physical leisure participation was quantified as the variety, frequency, and duration of participation. Data were analyzed using a series of hierarchical multiple linear regressions. The results showed that higher variety, frequency, or duration of physical leisure participation was associated with older males and with those who reported having better health, fewer depressive symptoms, and greater social support. Intrapersonal- and interpersonal-level factors play a relatively more important role in predicting physical leisure participation than factors at the community level. Understanding factors that relate to these three levels of participation has the potential to inform interventions that are tailored to individual profiles.

The First Naked Bismuth-Chalcogen Metal Carbonyl Clusters: Extraordinary Nucleophilicity of the Bi Atom and Semiconducting Characteristics.

Mixed bismuth-chalcogen-iron clusters [{EFe3(CO)9}Bi]- [E = Te (1a) or Se (1b)] were produced via the reduction of BiCl3 with [EFe3(CO)9]2- under mild conditions. X-ray analysis showed that both clusters 1a and 1b had a square-pyramidal geometry, where the naked Bi and chalcogen both adopted a distorted trigonal-pyramidal configuration with a stereoactive lone pair. Complexes 1a and 1b can be further functionalized by methylation and metalation, which permits the nucleophilicity of the 6s/5s and 6s/4s lone pairs to be compared. In the metalation, the 6s pair of the Bi atom in 1a and 1b had an extraordinary nucleophilicity toward the unsaturated Cr(CO)5 fragment, even in the presence of the more chemically active 5s or 4s pair, whereas in the case of methylation, only the 4s pair of Se could be selectively alkylated. Upon oxidation of 1a and 1b with suitable oxidizing agents, NaBiO3 or K2SeO3, Bi-E bonded tetrahedral complexes [{EFe2(CO)6}Bi]- [E = Te (4a) or Se (4b)] were formed by the elimination of one Fe(CO)3 vertex. X-ray photoelectron spectroscopy, X-ray absorption near-edge structure, and density functional theory (DFT) calculations showed that all of the Bi atoms in these complexes had oxidation states close to +1. Due to the electropositive character of the Bi atom, pronounced induced Bi···E inter- and intramolecular interactions were evident in 1a (1b), 4a (4b), and the metalated 3a (3b), where their linear-like ···Bi···E··· or zigzag-like ···Bi-E··· (E = Te or Se) chain or the Bi···E···E···Bi (E = Te or Se) dimeric chain can further expand into the two-dimensional network via nonclassical C-H···O(carbonyl) interactions, supported by noncovalent interaction index and DFT calculations. These positively charged Bi-induced Bi···E (E = Te or Se) and carbonyl-aided weak interactions can facilitate efficient electron transport within these ternary Bi-E-Fe or quaternary Bi-E-Fe-Cr cluster-based frameworks, resulting in semiconducting behavior with surprising ultranarrow energy gaps of 1.01-1.21 eV.

Leisure as an End, Not Just a Means, in Occupational Therapy Intervention.

Leisure is commonly treated as a means instead of an end goal of intervention. This approach, influenced by history and society's past values, does not reflect the fact that leisure is meaningful and unique to its participants and has a significant effect on their health. On the basis of the core values of the occupational therapy profession and its role in the health care system, in this article we advocate that occupational therapists should expand their focus to include leisure as a goal of intervention. Although adopting this proposed approach may not be easy, given that it involves challenges in reimbursement for services, potential competition with other health professions, and a twisting of the deep-rooted existing values of occupational therapists, we believe the proposed solutions address these concerns and shed light on how to make leisure a valued goal of intervention.

Consistency of participation over time among persons aging with physical disability as measured by a tool designed for use among community-based organizations.

BACKGROUND: Community participation measures for persons aging with disability were developed and evaluated to support community-based organizations (CBOs) with efficient assessment of change in participation and need for supports/services to facilitate participation. OBJECTIVE: To evaluate a set of nine activity domain measures to broadly assess community participation and change in participation over time. METHODS: A community-based sample (N = 323) of persons ages 45-65 responded to a survey with repeated measures three times annually (T1, T2, T3) between 2019 and 2022. Nine activity domain measures were developed based on extant research and evaluated with assistance from community-based support service providers. Statistical analyses employed T-tests and chi-square tests to assess change in participation over time, perceptions of participation satisfaction, and assistance needed to facilitate participation. Participants were asked if they thought changes were attributable to aging, the COVID-19 pandemic, or other factors. RESULTS: Findings showed varying levels of participation across the nine activity domains, with the lowest participation rate for employment and the highest participation rates for personal leisure and managing medications across T1, T2, and T3. Change in participation over the three-year period was limited; most change was reported as activity reduction. In general, respondents indicated that reduction was due to their aging or the COVID-19 pandemic. Personal assistance, transportation, environmental modifications, and improved health were identified as factors needed to help increase participation levels. CONCLUSION: The activity domain measures demonstrated efficiency in identifying participation rates and change. CBOs may deem them useful for assessing support and service needs to facilitate participation.

Correlations between Sagittal Parameters and Functional Scores in 65-Year-Old Osteoporotic Females with Vertebral Body Fracture under Low-Energy Mechanism.

Background: Vertebral compression fractures (VCFs) are the most common fragility fractures associated with low-energy injury mechanisms in postmenopausal women with osteoporosis. No clear consensus is currently available on the optimal timing for surgical intervention in specific cases. Methods: This study examined the correlations between sagittal parameters, functional scores, and the appropriate timing for surgical intervention during the recovery stage in patients with osteoporosis with thoracolumbar (TL) vertebral body fractures. A total of 161 women aged ≥ 65 years with osteoporosis were included in the study. Spinal sagittal parameters from standing plain films and functional outcomes as the Oswestry disability index (ODI) and the visual analogue scale (VAS) were collected. Results: We found that TL junction Cobb angle was significantly correlated with ODI > 30 (p < 0.001) and VAS > 6 (p < 0.001) and the discriminative values for predicting ODI > 30 and VAS > 6 were a TL kyphotic angle of 14.5° and 13.5°, respectively. Among women aged ≥ 65 years with osteoporosis, the back pain and functional impairment observed within 6 months following a compression fracture are associated with a greater TL kyphosis angle. Conclusions: This suggests that a more proactive approach may be necessary when addressing the conditions of these patients.

Removing home hazards for older adults living in affordable housing: A stepped-wedge cluster-randomized trial.

BACKGROUND: Falls are the leading cause of injury, disability, premature institutionalization, and injury-related mortality among older adults. Home hazard removal can effectively reduce falls in this population but is not implemented as standard practice. This study translated an evidence-based home hazard removal program (HARP) for delivery in low-income senior apartments to test whether the intervention would work in the "real world." METHODS: From May 1, 2019 to December 31, 2020, a stepped-wedge cluster-randomized trial was used to implement the evidence-based HARP among residents with high fall risk in 11 low-income senior apartment buildings. Five clusters of buildings were randomly assigned an intervention allocation sequence. Three-level negative-binomial models (repeated measures nested within individuals, individuals nested within buildings) were used to compare fall rates between treatment and control conditions (excluding a crossover period), controlling for demographic characteristics, fall risk, and time period. RESULTS: Among 656 residents, 548 agreed to screening, 435 were eligible (high fall risk), and 291 agreed to participate and received HARP. Participants were, on average, 72 years, 67% female, and 76% Black. Approximately 95.4% of fall prevention strategies and modifications implemented were still used 3 months later. The fall rate (per 1000 participant-days) was 4.87 during the control period and 4.31 during the posttreatment period. After adjusting for covariates and secular trend, there was no significant difference in fall rate (incidence rate ratio [IRR] 0.97, 95% CI 0.66-1.42). After excluding data collected during a hiatus in the intervention due to COVID-19, the reduction in fall rate was not significant (IRR 0.93, 95% CI 0.62-1.40). CONCLUSIONS: Although HARP did not significantly reduce the rate of falls, this pragmatic study showed that the program was feasible to deliver in low-income senior housing and was acceptable among residents. There was effective collaboration between researchers and community agency staff.

The Association Between Postural Sway and Preclinical Alzheimer Disease Among Community-Dwelling Older Adults.

BACKGROUND: It is unknown whether older adults with preclinical Alzheimer disease (AD) experience changes in postural sway compared with those without preclinical AD. The purpose of this study was to understand the effect of dual tasking on standing balance, or postural sway, for people with and without preclinical AD. METHODS: A cross-sectional analysis of baseline data from a longitudinal cohort study. Participants were cognitively normal older adults with and without preclinical AD. Postural sway (path length) was tested using a force plate under standard and dual task balance conditions. Dual task cost (DTC) was calculated to examine performance change in balance conditions. Logistic regression models were used to predict preclinical AD status as a function of DTC. RESULTS: 203 participants (65 preclinical AD+) were included. DTC for path length was significantly greater for participants with preclinical AD (DTC path length mean difference 19.8, 95% CI 2.6-37.0, t(201) = 2.29, p = .024). Greater DTC was significantly associated with increased odds of having preclinical AD (adjusted odds ratio for a 20-unit increase in DTC 1.16, 95% CI 1.02-1.32). CONCLUSIONS: Older adults with preclinical AD are more likely to demonstrate significantly greater DTC in postural sway than those without preclinical AD. Dual tasking should be integrated into balance and fall risk assessments and may inform early detection of preclinical AD.

The Stroll Safe outdoor falls prevention program: Participant experiences in eight community sites.

BACKGROUND AND OBJECTIVES: Outdoor falls can negatively impact the quality of life of community-dwelling older adults. Although there are differences in risk factors for indoor and outdoor falls, none of the existing evidence-based fall prevention programs specifically targets outdoors falls. To fill this gap, the Stroll Safe program was developed. The purpose of this study was to explore participant's experiences in the Stroll Safe program RESEARCH DESIGN AND METHODS: In this qualitative study, we conducted focus groups at eight community program sites with Stroll Safe program participants. Thematic analysis, with both deductive and inductive coding were used. Researcher triangulation was employed to increase trustworthiness of the findings RESULTS: Four major themes emerged from the data, including (1) Precipitants of behavioral change, (2) Behavioral change, (3) Program design, and 4) Enjoyment of program experience. Several sub-themes were also uncovered DISCUSSION AND IMPLICATIONS: Although the qualitative findings are consistent with the quantitative findings from the efficacy trial, the results also reveal benefits that were not captured by the quantitative analysis. In addition, the findings related to the influence of the group leader and program design can be used to guide future implementation science studies.

COVID-19: Factors Predicting Depressive Symptoms in People Aging With Long-Term Physical Disabilities.

The mental health impact of the COVID-19 pandemic may be greater than that of the viral infection. This impact is likely greater for disadvantaged groups such as people with long-term physical disabilities (PwLTPD). This cross-sectional study used a multiple linear regression model to examine factors associated with depressive symptoms and to understand their relative importance during the onset of the COVID-19 pandemic. The model explained 58% of the variance in depressive symptoms. Anxiety was the most important predictor, accounting for 8% of variance. Higher levels of anxiety, loneliness, and financial stress; prior diagnosis of depression; and non-Black race predicted a higher level of depressive symptoms in PwLTPD during the onset of the COVID-19 pandemic. Occupational therapy practitioners should strategically acknowledge predictors of depression that cannot be modified and actively address those that can be modified through evidence-based interventions to improve depressive symptoms in PwLTPD.

Influence of falls, fall-related injuries, and fear of falling on social participation in people aging with long-term physical disability: a cross-sectional study.

PURPOSE: This study examined prevalence and relationships among falls, injuries, fear of falling, and social participation in people aging with long-term physical disability (PAwLTPD). MATERIALS AND METHODS: A convenience sample of 474 PAwLTPD recruited from community agencies and social media as baseline of a longitudinal cohort study. Inclusion criteria: 45-65 years, self-reported physical disability for ≥5 years, and English-speaking. Self-report surveys of physical/mental health, falls in the past year, fear of falling, and Patient-Reported Outcomes Measurement Information System (PROMIS) ability and satisfaction with participation in social roles and activities measures were collected. RESULTS: Mean age 56.8 years; participants were mostly female (66.7%) and White (61.4%). Nearly 65% reported a fall; 56.6% of falls resulted in injury. Falls and fall-related injuries were associated with worse physical/mental health and presence of >5 health conditions. Seventy-five percent of participants reported fear of falling. Lower ability and satisfaction with participation were found in participants who fell and worried about falls. CONCLUSIONS: PAwLTPD are at increased risk of falls, fall-related injuries, and fear of falling, which affects their ability to engage in social activities. Future research is needed to understand circumstances associated with falls and to develop effective interventions to address falls in PAwLTPD.

Community-dwelling individuals aged 45­65 years who are aging with long-term physical disabilities report increased rates of falls, fall-related injuries, and fear of falling.People aging with long-term physical disabilities who experience falls report decreases in their social participation.Additional work within the rehabilitation field is needed to develop effective, evidence-based interventions to reduce the occurrence of falls among individuals aging with long-term physical disability.

Retention of Study Partners in Longitudinal Studies of Alzheimer Disease.

BACKGROUND: Study partners are required for all participants at Alzheimer's Disease Research Centers (ADRCs). Study partners' attitudes and beliefs may contribute to missed visits and negatively impact retention of participants in longitudinal AD studies. OBJECTIVE: Study partners (N = 212) of participants (Clinical Dementia Rating® [CDR]≤2) at four ADRCs were randomly surveyed to examine their facilitators and barriers to continued participation in AD studies. METHODS: Reasons for participation were analyzed with factor analysis and regression analysis. Effects of complaints and goal fulfillment on attendance were estimated with fractional logistic models. Open-ended responses were characterized with a Latent Dirichlet Allocation topic model. RESULTS: Study partners participated for personal benefit and altruism. They emphasized personal benefits more when their participants had a CDR > 0 than when they had a CDR = 0. This difference declined with participant age. The majority of study partners rated their ADRC participation as positive and meeting their goals. Although half reported at least one complaint, very few regretted participating. Those who reported that ADRC participation fulfilled their goals or had fewer complaints were more likely to have perfect attendance. Study partners requested more feedback about test results and better management of study visits. CONCLUSION: Study partners are motivated by both personal and altruistic goals. The salience of each goal depends on their trust in researchers and the participant's cognitive status and age. Retention may improve with perceived goal fulfillment and fewer complaints. Potential areas for improving retention are providing more information about the participant's test results and better management of study visits.

Sociodemographic Differences in Respondent Preferences for Survey Formats: Sampling Bias and Potential Threats to External Validity.

Objective: To explore sampling bias as a result of survey format selection by examining associations between characteristics of people aging with long-term physical disability (PAwLTPD) and their preferences for phone or web-based survey format. Design: A cross-sectional study using a secondary data analysis approach. Setting: Data were from an ongoing longitudinal cohort study conducted in the community. Participants: Convenience sampling was used. PAwLTPD who participated in year 2 of the longitudinal cohort study were included. Inclusion criteria were age 45-65 years, English speaking, and self-reported onset of a physical disability at least 5 years prior to study recruitment. Two participants completed the survey using both phone and web formats and were thus excluded; 387 participants (N=387) were included in the analysis. Interventions: Not applicable. Main Outcome Measures: Choice of survey format and demographics (age, sex, race and ethnicity, marital status, living arrangement, socioeconomic status) were collected in addition to self-rated physical health. Results: Participants were on average 58.2±5.6 years old. A total of 33% were male, and 62% were White. Approximately 40% of participants completed phone surveys. The phone survey group was significantly older (t=-4.76, P<.001) and had lower education (U=11133, z=-6.65, P<.001) and lower self-rated physical health (U=15420, z=-2.38, P=.017) than the web survey group. Participants who were White (χ2=60.69; df=1; P<.001; odds ratio [OR], 0.18) or were in a long-term relationship were less likely to choose phone surveys (χ2=42.20; df=1; P<.001; OR, 0.21). Those who earned $10,008 or less annually (χ2=53.90; df=1; P<.001; OR, 5.22) or who lived alone (χ2=36.26; df=1; P<.001; OR, 3.64) were more likely to choose phone surveys. Participants with paid work (χ2=16.81, df=1, P<.001) tended to select web-based surveys, while those on disability leave (χ2=9.61, df=1, P<.01) were more likely to choose phone surveys. Conclusions: Sociodemographics are associated with survey format choice in PAwLTPD. Findings largely support the existing understanding of digital literacy but also provide insight into the potential occurrence of sampling bias when multiple survey format options are not offered. These findings have implications for investigators who aim to reach a more representative sample of people with disabilities.

A protocol for Removing Environmental Barriers to Independent Living (REBIL): An adapted evidence-based occupational therapy intervention to increase community participation for individuals aging with long-term physical disabilities.

Background: People aging with long-term physical disabilities (PAwLTPD) are living longer and experiencing the challenges of aging, including the onset of secondary and age-related health conditions. PAwLTPD are at high risk of falls, fall injuries, diminished functional abilities, and compromised participation. However, no available programs support PAwLTPD to participate safely at home and in the community. The proposed study is to examine the feasibility and efficacy of an adapted intervention: Removing Environmental Barriers to Independent Living (REBIL). Method/Design: A single-blinded randomized controlled trial (RCT) will be conducted. Participants who are 45-65 years old; self-report difficulty with ≥2 daily activities; have had a physical disability for ≥5 years; and live within 60 miles of the research lab are eligible. All participants will receive an initial in-home evaluation before randomization. The treatment group will receive REBIL (total five visits), which is tailored. The waitlist control group will be offered the same intervention after 6-month follow-up. Expected outcomes are high acceptability, fidelity, and adherence; low safety risk; improved community participation and daily activities performance; and fewer environmental barriers and fall hazards. Discussion: Findings will serve as preliminary evidence for occupational therapy community practice. Outcomes will also inform future large, pragmatic trials. Trial Registration: ClinicalTrials.gov identifier NCT04589988.

Aging with Disability Symptoms and Ability to Participate in, and Satisfaction with, Social Participation among Persons Aged 45-64.

Pain, fatigue, and depression, considered aging with disability (AwD) symptoms, are known to be substantially higher among middle-aged adults with long-term disability compared to their age peers. Participation has been recognized as an important component of health. This cohort survey study reports findings on the relationship between AwD symptoms and ability to participate in, and satisfaction with participation in, social roles and activities using PROMIS measures. Data were collected at three time points from individuals aged 45-64 with an average of two decades of disability duration and primarily living in the state of Missouri, USA. This study reports on Time 1 (T1) and Time 3 (T3), pre- and post-COVID-19 pandemic declaration, respectively. Multiple regressions using both individual AwD symptoms and a composite measure demonstrated that having more pain, fatigue, and depression was associated with worse participation outcomes. Lower physical function scores were also related to lower participation scores, as was being female and living with others, and having more income reduced participation. Better physical health and identifying as African American/Black were associated with higher participation scores. Our findings suggest that AwD symptoms, along with other sociodemographic and health factors, play a substantial role in the social participation outcomes for persons aging with disability and remain consistent over time.

Interventions to promote independent participation among community-dwelling middle-aged adults with long-term physical disabilities: a systematic review.

PURPOSE: People aging with long-term physical disabilities (PAwLTPD) are aging at an accelerated rate beginning in middle-age. They face age-related challenges in conjunction with their existing disabilities; thus, maintaining independence as they age is often difficult. The aim of this systematic review was to examine the effectiveness of rehabilitation interventions for middle-aged PAwLTPD to participate independently in the home and community. MATERIALS AND METHODS: We searched four databases - MEDLINE, CINAHL, Web of Science, and EMBASE - for studies published from January 2005 to December 2020. Information from included studies was extracted using a critical appraisal form. Studies were categorized based on common themes, assigned level of evidence, and assessed for risk of bias. RESULTS: Fourteen articles were included. Common themes derived were fall risk reduction, functional capacity, community mobility, and function within the home. The strongest evidence supports wheelchair skills training programs (WSTPs) among manual wheelchair users and targeted paretic limb exercise post-stroke. Moderate evidence supports exercise and multicomponent interventions for those with multiple sclerosis, adaptive strategy training and WSTPs to improve satisfaction with mobility for power wheelchair users, and home modifications/assistive technology for mobility-impaired individuals. CONCLUSION: Interventions with strong and moderate evidence should be routinely offered for middle-aged PAwLTPD. Future research should focus on developing evidence-based interventions for middle-aged PAwLTPD.IMPLICATIONS FOR REHABILITATIONMiddle-aged PAwLTPD face the same aging-related challenges as people without disabilities but will experience additional difficulties due to compounding effects of long-term health conditions and aging.Current effective interventions to promote participation for middle-aged PAwLTPD have been measured over a wide range of outcomes, and many interventions should be used by clinicians on a case-by-case basis.Wheelchair skills training was found to have the strongest evidence and is recommended for use with middle-aged PAwLTPD who use manual and power wheelchairs.

Factors associated with IADL independence: implications for OT practice.

BACKGROUND: Globally, the population is aging. Instrumental activities of daily living (IADL) are an important component of independent function and impact the ability of older adults to age in place. Therefore, factors associated with IADL independence warrant further study. OBJECTIVE: To explore the association of age, depressive symptoms and leisure participation with IADL independence, and the relative importance of these three factors in predicting IADL independence. METHODS: A cross-sectional design using an existing data set was employed. Older adults age 60 and older (n = 98) who resided in senior housing or their own home/apartment were included in the study. A hierarchical multiple regression analysis was employed. RESULTS: The second model predicting IADL independence using age, depressive symptoms and level of leisure participation was significant (F(3,96) = 15.57, p < 0.001) and explained 31.00% of the variance in IADL independence compared to the first regression model, which included age alone (R2 adjusted = 18.00%). Age was the strongest of the three predictors, accounting for 11.40% of the variance in IADL independence. Depressive symptoms and participation in leisure activities were also significant predictors, their unique contributions being 7.30 and 4.30%, respectively. CONCLUSION AND SIGNIFICANCE: Age, depressive symptoms and leisure participation are all significant predictors of IADL independence among older adults. Therefore, according to our preliminary findings, leisure participation and non-pharmacological interventions for depressive symptoms warrant attention in practice in relation to IADL independence.

The Virtual Threat Effect: A Test of Competing Explanations for the Effects of Racial Stereotyping in Video Games on Players' Cognitions.

Past research provides evidence that embodying a racially stereotyped African American video game character triggers stereotyped thinking among White players. However, the mechanisms through which virtual racial embodiment of a negatively stereotyped character in a video game impacts stereotyped thinking are still unknown. This study expands on past research and utilizes a between-subjects experimental design to test two possible theoretical explanations: the virtual threat effect and presence. On the one hand, embodying a negatively stereotyped African American character may elicit stereotyped thinking among White players due to the mere exposure to the threatening stereotype. According to this explanation, negative affective response to the threatening stimulus predicts stereotyping. On the other hand, the process of embodying, not just observing, the stereotyped African American character suggests that presence in the game may determine how impactful the game imagery is on White players' stereotyping of African Americans. In this case, level of presence would predict stereotyping. The findings of this study advance research by providing evidence of a psychological explanation for the negative effects of embodying a racially stereotyped video game character on players' race-related perceptions. We conceptualize the "virtual threat effect," which may be applied in additional contexts to understand how embodying stereotyped representations of outgroups in virtual environments may negatively affect individuals' perceptions and support of these groups.

Does Facebook promote self-interest? Enactment of indiscriminate one-to-many communication on online social networking sites decreases prosocial behavior.

Abstract Communication tools on social networking sites (SNSs) provide users with an efficient way to distribute information to the public and/or their friends simultaneously. In this article, we show that this kind of indiscriminate one-to-many (i.e., monologue) communication, in which the diverse interests of recipients are not considered, may induce a tendency toward egocentrism that interferes with other-oriented concerns, resulting in a reduced inclination to display prosocial behavior. In Experiment 1, participants induced to post a public communication subsequently allocated less money to anonymous strangers in the dictator game than did control participants. In Experiment 2, participants directing a post about participation in an experiment to their Facebook friends volunteered to help code fewer data sheets than did controls. Moreover, an egocentric state was shown to mediate the relationship between indiscriminate one-to-many communication and helping behavior. We provide the first demonstration that indiscriminate one-to-many communication on online social networks may be associated with a tendency toward self-interest. Our results suggest that the prevalence of monologue communication on SNSs may induce an egocentric tendency that undermines the likelihood of prosocial behavior.
