Exercise Intensity Among Older Adults Participating From Home in Remotely Delivered EnhanceFitness.

We aimed to examine exercise intensity among older adults participating from home in remotely delivered EnhanceFitness (Tele-EF). Exercise intensity was assessed through Fitbit-measured heart rate and the Borg 10-point rating of perceived exertion over 1 week of a 16-week exercise program. Outcomes included mean minutes spent at or above the heart rate reserve calculated threshold for moderate intensity and mean rating of perceived exertion. Pearson and Spearman rank correlations were used to examine associations between baseline characteristics with exercise intensity. During the 60-min classes, the 55 participants achieved moderate intensity for a mean of 21.0 min (SD = 13.5) and had a mean rating of perceived exertion of 4.9 (SD = 1.2). There were no significant associations between baseline characteristics and exercise intensity. Older adults can achieve sustained moderate-intensity exercise during Tele-EF supervised classes. Baseline physical function, physical activity, and other health characteristics did not limit ability to exercise at a moderate intensity, though further investigation is warranted.

Female cancer survivor perspectives on remote intervention components to support physical activity maintenance.

PURPOSE: Physical activity minimizes the side effects of cancer; yet, participation rates among cancer survivors are low. Technological innovations are promoted as efficient means for communication and remote monitoring, but little is known about acceptability among female cancer survivors. The purpose of this study was to examine female cancer survivor perspectives on remote monitoring and communication to support independent, physical activity maintenance after completing a structured, facility-based program. METHODS: Participants were 19 female cancer survivors (mean age 56.3) recruited after completing a 12-week exercise-based oncology rehabilitation program. Semi-structured interviews were conducted with participants following a 4-week pilot trial of a tailored text message, FitBit®, and health coach intervention to support independent physical activity maintenance. All interviews were audio-recorded and transcribed. Transcripts from the interviews were iteratively coded by two team members using a thematic analysis. RESULTS: Participants reported acceptance and satisfaction with remote monitoring and communication. Emergent themes related to technology-based support for physical activity maintenance included the following: (1) accountability to a remote partner; (2) plan Bs, planning for barriers; (3) the habit cycle; (4) convenience through technology; and (5) reclaiming health ownership following a cancer diagnosis. CONCLUSIONS: Participants attributed physical activity maintenance to accountability enabled by technology. Communication based on remote monitoring was perceived as encouraging and not intrusive, during the transition to a home program. IMPLICATIONS FOR CANCER SURVIVORS: This study highlights the importance of accountability and support for physical activity adherence and the positive role that technology can provide for female cancer survivors to regain control of health management.

Depression and activity-limiting fall worry among older adults: longitudinal reciprocal relationships.

OBJECTIVES: Late-life depression, falls, and fall worry are public health problems. While previous research confirms the cross-sectional relationship between depression and fall worry, few longitudinal studies have examined whether changes in fall worry are associated with changes in depressive illness and vice versa. This study examined longitudinal relationships between probable major depression (PMD) and activity-limiting fall worry (ALW). DESIGN, SETTING, PARTICIPANTS, MEASUREMENTS: This longitudinal panel observational study used data from the National Health and Aging Trends Study (NHATS) waves 5 (referred to as T1 in this study) and 6 (T2), conducted in 2015 and 2016, respectively (N = 6,299, aged 65 and older). We examined associations of new and continued ALW between T1 and T2 with T2 PMD, controlling for T1 PMD; and associations of new and continued PMD between T1 and T2 with T2 ALW, controlling for T1 ALW. We used χ2 and t tests for descriptive statistics and logistic regression for multivariable analysis. RESULTS: Those with new ALW at T2 had significantly greater odds of T2 PMD compared to those without ALW at both time points (AOR = 2.64, 95% CI = 1.98-3.51), and those with new PMD at T2 had significantly greater odds of T2 ALW (AOR = 2.42, 95% CI = 1.66-3.52). Those with continued PMD also had greater odds of T2 ALW compared to those without PMD at either time point (AOR = 2.31, 95% CI = 1.62-3.29). CONCLUSIONS: The findings add to knowledge about bidirectional (mutually reinforcing) relationships between depression and activity-limiting fall worry. Innovative interventions are needed to reduce both late-life depression and activity-limiting fall worry.

Efficacy, feasibility, and acceptability of a novel technology-based intervention to support physical activity in cancer survivors.

PURPOSE: Physical activity is known to minimize the long-term side effects of cancer treatment. Yet, rates of physical activity participation by cancer survivors are significantly lower compared to the general population. The purpose of this pilot study was to examine the efficacy, feasibility, and acceptability of a technology-based intervention to promote maintenance of physical activity after completing an exercise-based oncology rehabilitation program. METHODS: The pre-post 4-week intervention included support delivered through tailored text messages, Fitbit® self-monitoring, and brief health coaching sessions. The primary outcome measure was accelerometer-assessed physical activity levels. Self-efficacy, self-regulation, social support, fatigue, sleep disturbance, depression, and Fitbit® step counts were assessed as secondary outcomes. RESULTS: Twenty-four participants (20 females; mean age = 57.9 years ± 10.4) completed the intervention. Mean daily step counts and weekly minutes of moderate-to-vigorous intensity physical activity were maintained after the intervention, as compared to baseline levels achieved at the end of 12 weeks of exercise-based oncology rehabilitation. Both self-regulation (goal setting, relapse prevention) and fatigue severity increased significantly post intervention as compared to baseline (p = 0.05 and p = 0.02, respectively). Qualitative responses demonstrated overall satisfaction with intervention components. CONCLUSIONS: Results demonstrate efficacy of the intervention for maintenance of physical activity levels achieved during exercise-based oncology rehabilitation. Low attrition and high satisfaction provide evidence for both the acceptability and feasibility of the intervention components. Exercise interventions post oncology treatment provide multiple benefits for cancer survivors, yet continued maintenance after program completion is challenging. Technological options offer low-cost, accessible modes to deliver continued monitoring and support beyond traditional facility-based programs.

Rehabilitation Services Use and Patient-Reported Outcomes Among Older Adults in the United States.

OBJECTIVE: To characterize rehabilitation service use among community-dwelling older adults in the United States by identifying predictors of rehabilitation utilization, patient-reported functional improvement, and rehabilitation goal attainment. DESIGN: Cross-sectional analysis of the 2015 National Health and Aging Trends Study, which used an age-stratified, multistage sampling design and oversampled blacks and the oldest old (≥85y). SETTING: Standardized, in-person home interviews and physical performance testing. PARTICIPANTS: Nationally representative sample of community-dwelling Medicare beneficiaries (N=7487) aged ≥65 years. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Rehabilitation services use (physical therapy, occupational therapy, and speech therapy) across all settings in the last year, patient-reported functional improvement, and patient-reported rehabilitation goal attainment. RESULTS: Twenty percent of older adults reported rehabilitation use in the last year. In a multivariable model, rehabilitation use was significantly lower among blacks and higher among those with higher education, chronic medical conditions, pain, history of falls, and severe limitations in physical performance. Overall, 72% reported functional improvement during rehabilitation, and 75% reported meeting their goals by discharge. Improved function was associated with longer duration of rehabilitation. A significantly lower percentage of older adults with bothersome pain and severe physical limitations reported meeting rehabilitation goals. CONCLUSIONS: Most older adults who received rehabilitation reported functional improvement and meeting rehabilitation goals. However, social disparities were evident with lower rehabilitation utilization among blacks and those with less education. Importantly, functional improvement and goal attainment did not vary by demographics or diagnoses. Longer duration of rehabilitation and improved pain management may be necessary for functional improvement and goal attainment.

A psychometric examination of multimorbidity and mental health in older adults.

OBJECTIVES: Multimorbidity, the presence of multiple chronic medical conditions, is particularly prevalent in older adults. We examined the relationship of multimorbidity with mental health, social network and activity limitations in the National Health and Aging Trends Study, a nationally representative, age-stratified sample of older adults. METHOD: After excluding participants who used a proxy to complete the survey and those who did not answer any of the depressive symptoms, anxiety symptoms and positive and negative affect items, the final sample was 7026. A disease count of 10 conditions (heart disease, hypertension, arthritis, osteoporosis, diabetes, lung disease, stroke, dementia, cancer, fracture) was used. RESULTS: Factor analysis indicated a one factor structure for disease count was tenable, although cancer did not appear to fit the model. Therefore, a count of the nine other diseases was used. Disease count was related to increased depressive symptoms, anxiety symptoms and negative affect and less positive affect. All individual diseases including cancer were related to worse mental health as was having two or more conditions. Disease count, having two or more conditions and several individual diseases (heart disease, hypertension, arthritis, cancer and fracture) were also related to increases in social network size while other individual diseases (osteoporosis, diabetes, lung disease, stroke and dementia) were related to decreases in social network size. All the measures of multimorbidity and individual diseases were associated with the increased odds of activity limitations. CONCLUSIONS: Results support a broader focus for older adults with multimorbidity that includes mental health needs.

The Relationship of Perceived Risk and Biases in Perceived Risk to Fracture Prevention Behavior in Older Women.

BACKGROUND: A bias in perceived risk for health outcomes, including fracture, exists. PURPOSE: We compared perceived risk and biases in perceived risk for fracture to fracture preventive behavior. METHODS: Women over age 55 (n = 2874) completed a survey five times over 5 years, and data was pulled from the medical record. Perceived risk was measured by asking women to rate their risk of fracture compared to similar women. Actual risk was measured using FRAX score. Bias was measured using an interaction between perceived and actual risk. RESULTS: Higher perceived risk was related to lower quality of life and self-reported health, more medication and calcium use, increased bone density scan use, and less walking. Bias was only associated with less medication use. Neither perceived risk nor bias predicted medication adherence. CONCLUSIONS: Perceived risk, but not bias, may predict different fracture prevention behaviors. Clinicians may need to base interventions on risk perceptions.

Physical Therapist and Patient Perspectives on Mobile Technology to Support Home Exercise Prescription for People With Arthritis: A Qualitative Study.

Introduction Mobile applications (apps) for exercise prescription may enhance communication between healthcare providers and patients while addressing common barriers to exercise among people with osteoarthritis. However, little is known about preferences and barriers to the use of mobile apps by physical therapists or people aging with osteoarthritis. Therefore, we aimed to examine physical therapist and patient perspectives on mobile apps to support physical therapist-prescribed home exercise for people with osteoarthritis. Methods Eighteen physical therapists and 17 individuals with a history of physical therapy for osteoarthritis participated in the study. Focus groups (n = 6, three each with physical therapists and patients) were conducted to gather perspectives on three commercially available mobile apps designed for physical therapy exercise prescription. Semi-structured questions assessed feature preferences, ease of use, exercise completion support, clinical feasibility, and potential barriers and facilitators to using the apps. Recordings of the focus groups were transcribed verbatim. The study team iteratively coded transcripts using thematic analysis. Results Perspectives of patients and physical therapists intersected but differed on the mobile apps. All patients preferred video exercise prescription over traditional methods and both patients and therapists predicted challenges and opportunities with mobile communication. Four themes emerged: accountability, data-driven, communication boost, and duality of technology. Facilitators of home exercise through mobile apps included exercise tracking, feedback loop, personalization, and the potential for reduced in-person visits. Barriers included technological challenges, complex interface design, lack of universal applicability, and security concerns. Conclusion Mobile app technology has the potential to support exercise adherence for people with osteoarthritis. However, patients' and therapists' perspectives differ and highlight numerous challenges that limit the universal clinical adoption of this technology. While physical therapists acknowledged the potential to improve the rehabilitation experience with mobile apps, there was concern about reimbursement and time constraints in the current fee-for-service environment.

Older adults with communication disabilities and their use of communication support at doctor's visits: a nationally representative study.

PURPOSE: Older adults with communication disabilities (CDs) experience barriers to receiving care and face a paucity of accommodations for their disability. Utilizing someone that supports communication with healthcare providers (communication support persons) may be a way that this group self-supports their disability. We examined if this utilization was independently associated with CDs among older adults. We also sought to understand if socioeconomic factors were associated with utilization. METHODS: We used the 2015 National Health and Aging Trends Survey (NHATS) to conduct a cross-sectional analysis of Medicare beneficiaries (n = 5954) with functional hearing, expressive, or cognitive difficulties. We calculated a weighted, population prevalence and an adjusted prevalence ratio (APR) controlling for sociodemographic, health and other disability factors. RESULTS: Among community dwelling older adults, having CDs was associated with higher utilization of a communication support person at medical visits (APR: 1.41 [CI: 1.27 - 1.57]). Among adults with CDs, Black adults and women had lower levels of utilization as compared to White adults and men, respectively. CONCLUSION: Communication support persons may be a way that older adults with CDs self-support their disability. However, not all older adults with CDs bring someone and variation by social factors could suggest that unmet support needs exist.

Over half of older adults with communication disabilities do not utilize a communication support person at doctors' visits, and utilization differs by race and gender.Rehabilitation professionals should educate their older adult patients with communication disabilities on this practice and collaborate with speech-language pathologists (SLPs) and audiologists (AuDs) on how to accommodate this population's disability.SLPs and AuDs can directly train support persons, other rehabilitation professionals, and physicians on accommodating these patients. For patients who don't bring a support person, SLPs and AuDs can plan alternative communication disability supports to use in healthcare settings, so that all older adults with CDs can equitably access their healthcare.

Exploring the implementation potential of physical activity assessment and prescription tools in physical therapy practice: a mixed-method study.

BACKGROUND: Despite the benefits of physical activity (PA), especially related to aging, physical therapists do not perform regular PA prescriptions secondary to various barriers, including lack of tools. Therefore, we developed the Inventory of Physical Activity Barriers (IPAB). OBJECTIVE: Explore potential solutions that could address the current lack of PA prescription among United States-based physical therapists treating patients 50 years and older. METHOD: A convergent parallel mixed-method design consisting of focus groups and self-report questionnaires. Descriptive statistics were used for all quantitative variables. Focus groups were thematically coded. RESULTS: The 26 participants had 8.6 years (SD = 6.4) of clinical experience, 88.4% (n = 23) reported they regularly have PA conversations with patients, 65.4% (n = 17) regularly assess PA levels, and 19.2% (n = 5) regularly provide PA prescriptions. We identified three themes: 1) opportunities and challenges related to PA prescriptions; 2) lack of standardization in PA assessments and interventions; and 3) implementation potential for innovative solutions that address the current informal PA assessments and interventions. CONCLUSION: Physical therapists are amenable to incorporating innovative solutions that support physical activity prescription behavior. Therefore, we recommend the continued development and implementation of PA assessment and prescription tools.

Prevalence and sociodemographic characteristics of US community-dwelling older adults with communication disabilities, using the national health and aging trends survey.

INTRODUCTION: Identifying the population-level prevalence of a disability group is a prerequisite to monitoring their inclusion in society. The prevalence and sociodemographic characteristics of older adults with communication disabilities (CDs) are not well established in the literature. In this study we sought to describe the prevalence and sociodemographic characteristics of community-dwelling older adults experiencing difficulties with understanding others or being understand when communicating in their usual language. METHODS: We conducted a cross-sectional analysis of the National Health and Aging Trends Survey (2015), a nationally representative survey of Medicare beneficiaries ages ≥ 65 years old (N = 7,029). We calculated survey weight-adjusted prevalence estimates by mutually exclusive subgroups of no, hearing only, expressive-only, cognitive only, multiple CDs, and an aggregate any-CD prevalence. We described race/ethnicity, age, gender, education, marital status, social network size, federal poverty status, and supplemental insurance for all groups. Pearson's chi-squared statistic was used to compare sociodemographic characteristics between the any-CD and no-CD groups. RESULTS: An estimated 25.3% (10.7 million) of community-dwelling older adults in the US experienced any-CDs in 2015; approximately 19.9% (8.4 million) experienced only one CD while 5.6% (2.4 million) had multiple. Older adults with CDs were more likely to be of Black race or Hispanic ethnicity as compared to older adults without CDs (Black 10.1 vs. 7.6%; Hispanic: 12.5 vs. 5.4%; P < 0.001). They also had lower educational attainment (Less than high school: 31.0 vs 12.4%; P < 0.001), lower poverty levels (<100% Federal poverty level: 23.5% vs. 11.1%; P < 0.001) and less social supports (Married: 51.3 vs. 61.0%; P < 0.001; Social network ≤ 1 person: 45.3 vs 36.0%; P < 0.001). CONCLUSIONS: The proportion of the older adult population experiencing any-CDs is large and disproportionately represented by underserved sociodemographic groups. These findings support greater inclusion of any-CDs into population-level efforts like national surveys, public health goals, health services, and community research aimed at understanding and addressing the access needs of older adults who have disabilities in communication.

Physical function in older adults with and without a cancer history: Findings from the National Health and Aging Trends Study.

BACKGROUND: Previous studies identified physical function limitations in older cancer survivors, but few have included objective measures and most focused on breast and prostate cancer survivors. The current study compared patient-reported and objective physical function measures between older adults with and without a cancer history. METHODS: Our cross-sectional study used a nationally representative sample of community-dwelling, Medicare beneficiaries from the 2015 National Health and Aging Trends Study (n = 7495). Data collected included patient-reported physical function, including a composite physical capacity score and limitations in strength, mobility, and balance, and objectively measured physical performance metrics, including gait speed, five time sit-to-stand, tandem stand, and grip strength. All analyses were weighted to account for the complex sampling design. RESULTS: Thirteen percent of participants (n = 829) reported a history of cancer, of which more than half (51%) reported a diagnosis other than breast or prostate cancer. In models adjusted for demographics and health history, older cancer survivors had lower Short Physical Performance Battery scores (unstandardized beta [B] = -0.36; 95% CI: -0.64, -0.08), slower gait speed (B = -0.03; 95% CI: -0.05, -0.01), reduced grip strength (B = -0.86; 95% CI: -1.44, -0.27), worse patient-reported composite physical capacity (B = -0.43; 95% CI: -0.67, -0.18) and patient-reported upper extremity strength (B = 1.27; 95% CI: 1.07, 1.50) compared to older adults without cancer. Additionally, the burden of physical function limitations was greater in women than in men, which may be explained by cancer type. CONCLUSIONS: Our results extend studies in breast and prostate cancer to show worse objective and patient-reported physical function outcomes in older adults with a range of cancer types compared to those without a cancer history. Moreover, these burdens seem to disproportionately affect older adult women, underscoring the need for interventions to address functional limitations and prevent further health consequences of cancer and its treatment.

Remotely Delivered Exercise to Rural Older Adults With Knee Osteoarthritis: A Pilot Study.

OBJECTIVE: EnhanceFitness (EF) is an evidence-based exercise program recommended for management of osteoarthritis (OA). However, access to EF is limited in rural areas. Accordingly, we evaluated the feasibility and acceptability of remotely delivered EF (tele-EF) in rural, community-dwelling older adults with symptomatic knee OA. METHODS: A single-arm pilot trial of tele-EF classes was conducted. Videoconferencing was used to livestream the instructor-led, 1-hour EF classes 3 days/week for 12 weeks. Outcomes were assessed at baseline and immediately post intervention. RESULTS: A total of 15 of 27 potential participants (55%) were screen eligible and enrolled into the trial. Participants had a median age of 70 years (interquartile range: 67-75), and 14 (93%) were women. The median EF class attendance rate was 91% (interquartile range: 85%-94%). Knee pain, as measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS), improved significantly from baseline to the 12-week end point (mean difference = -11.4 [95% confidence interval (CI): -20.9 to -2.0]; P = 0.02). In addition, participants' self-reported knee function improved significantly (mean difference in KOOS function score = -11.8 [95% CI: -18.4 to -5.2]; P < 0.01) as well as their physical capacity (mean difference in Timed Up and Go test time = 1.8 seconds [95% CI: 0.2-3.4]; P = 0.03). All participants (100%) were very satisfied with tele-EF classes, and 12 participants (86%) reported that their condition had much improved or very much improved since beginning the EF exercise program. Lastly, there were no serious adverse events. CONCLUSION: Findings from this pilot trial indicate that tele-EF is feasible and acceptable in rural older adults with knee OA.

Physical Activity and Physical Activity Participation Barriers Among Adults 50 Years and Older During the COVID-19 Pandemic.

OBJECTIVE: We examined changes in physical activity from pre-COVID-19 to during the COVID-19 pandemic and the factors associated with reduced physical activity levels among adults 50 yrs and older. DESIGN: Participants of a validation study were stratified into being "less active than before" or "equally or more active than before" COVID-19. Multivariable manual backward analyses were used to identify self-reported barriers associated with the reduction in physical activity. RESULTS: Reduced physical activity levels during COVID-19 were reported among 244 of 503 participants (43%). After adjusting for demographics and health conditions, factors that increased the odds of reduced physical activity levels during COVID-19 were lacking access to workout places, feeling too anxious, and difficulty committing to physical activity. Factors that decreased the odds of reduced physical activity levels during COVID-19 were self-identifying a heart- or lung-associated diagnosis that impacts physical activity and having a 12-mo retrospective history of falling. CONCLUSIONS: The physical activity participation barriers identified to be associated with a reduction in physical activity can be used as a starting point for a conversation regarding physical activity participation during COVID-19.

Nutrition Risk is Associated With Falls Risk in an Observational Study of Community-Dwelling, Rural, Older Adults.

OBJECTIVES: Poor nutritional status is a risk factor for falls and impedes recovery from falls in older adults. The primary objective of this study was to investigate the relationship between nutrition status and fall risk over time in a cohort of older adults. METHODS: Using an observational analytic study design, we collected demographic, fall risk, nutrition risk, food insecurity, and incident falls data from community-dwelling older Vermonters. RESULTS: Data from 708 participants (70.3 years ± 6.6; 82% female) indicate a significant association between fall risk and nutrition risk (p < 0.001), fall risk and food insecurity (p < 0.001), and food insecurity and nutrition risk (p < 0.001). After adjusting for potential confounders, elevated nutrition risk was significantly associated with an incident fall over the next 6 months (p < 0.05). CONCLUSION: Given the evidence for an association between nutrition status and falls, additional research, in a more diverse population, is needed to understand the nuances of these relationships.

Remotely delivered exercise to older rural cancer survivors: a randomized controlled pilot trial.

PURPOSE: The study aimed to determine the feasibility of remotely delivered exercise (tele-exercise) for older, rural cancer survivors and to explore the effects of tele-exercise on physical function, physical activity, and patient-reported outcomes. METHODS: Participants were rural cancer survivors age ≥ 60 years (79% female; mean age 70.4 ± 5.7) randomly assigned to the remotely delivered EnhanceFitness (tele-EF) exercise program, inclusive of aerobic, strength, and balance training and led by American Council on Exercise certified instructors for 1 h, 3 days/week for 16 weeks (n = 20) or to a waitlist control group (n = 19). We assessed feasibility, physical function, accelerometer-measured physical activity, and patient-reported outcomes at baseline and post intervention. RESULTS: Among those screened as eligible, 44 (64%) consented to participate with 39 randomized after completing baseline measures. Attrition was equivalent between groups (n = 1, each) with 95% completing the study. The median class attendance rate was 86.9% (interquartile range: 79-94%). Compared to controls, tele-EF participants had statistically significant improvement in the five-time sit-to-stand test (- 3.4 vs. - 1.1 s, p = 0.03, effect size = 0.44), mean daily light physical activity (+ 38.5 vs 0.5 min, p = 0.03, effect size = 0.72) and step counts (+ 1977 vs. 33, p = 0.01, effect size = 0.96). There were no changes in self-efficacy for exercise, fatigue, or sleep disturbance between groups. CONCLUSIONS: Findings indicate that tele-EF is feasible in older, rural cancer survivors and results in positive changes in physical function and physical activity. IMPLICATIONS FOR CANCER SURVIVORS: Tele-EF addresses common barriers to exercise for older, rural cancer survivors, including limited accessible opportunities for professional instruction and supervision.

The Inventory of Physical Activity Barriers for Adults 50 Years and Older: Refinement and Validation.

BACKGROUND AND OBJECTIVES: Due to health consequences associated with insufficient physical activity (PA), particularly among aging adults, health care providers should assess and address lack of PA participation. Addressing lack of PA means developing individualized PA prescriptions that incorporate solutions to PA participation barriers. Assessing PA participation barriers can be done through the Social Ecological Model-based Inventory of Physical Activity Barriers Scale (IPAB). This study aimed to refine the initial 40-item IPAB and determine its reliability and validity. RESEARCH DESIGN AND METHODS: Five hundred and three community-dwelling adults 50 years and older completed a demographic and health questionnaire, the Physical Activity Vital Sign, the IPAB, and a feedback questionnaire. For scale refinement, half of the data were used for exploratory factor analysis and the other half for confirmatory factor analysis. The refined scale underwent reliability and validity assessment, including internal consistency, test-retest reliability, and construct validity. RESULTS: The refined scale contains 27 items consisting of 7 factors and 1 stand-alone item: (a) environmental, (b) physical health, (c) PA-related motivation, (d) emotional health, (e) time, (f) skills, (g) social, and (h) energy (a stand-alone item). The 27-item IPAB has good internal consistency (alpha = 0.91) and high test-retest reliability (intraclass correlation coefficient = 0.99). The IPAB's mean scores were statistically different between those who met the recommended levels of PA and those who did not (p < .001). DISCUSSION AND IMPLICATIONS: The information gathered through the IPAB can guide discussions related to PA participation barriers and develop individualized PA prescriptions that incorporate solutions to the identified barriers.

Evaluation of Electronic and Pen-and-Paper Formats of the Inventory of Physical Activity Barriers: A Randomized Crossover Study.

BACKGROUND: The Inventory of Physical Activity Barriers (IPAB) assesses physical activity participation barriers. Development, refinement, and psychometric evaluation of the IPAB occurred via an electronic format. However, various circumstances may require using a pen-and-paper format. As instrument formats are not always interchangeable, the authors aimed to establish whether 2 different formats (electronic and pen and paper) can be used interchangeably for the IPAB. METHODS: This randomized crossover study included 66 community-dwelling adults aged 50 years and older (mean age = 73 [SD = 7.6]). Half the sample completed the electronic format of the IPAB first and the pen-and-paper format second, and the other half completed them in reverse order. Tests of equivalence and a Bland-Altman plot were performed. RESULTS: The intraclass correlation coefficient between formats was .94, and kappa was .68. The mean difference between the 2 administration forms of the IPAB was 0.002 (P = .96). Both administration formats had high internal consistency (Cronbach alpha = .92 and .93) and illustrated construct validity (P ≤ .001 for both administration formats). CONCLUSION: Pen-and-paper and electronic formats of the IPAB are equivalent and, thus, can be used interchangeably among non-Hispanic whites who are highly educated. The format should be used consistently if completing preintervention and postintervention evaluations or comparing scores.

A Feasibility Study of Multi-Component Fall Prevention for Homebound Older Adults Facilitated by Lay Coaches and Using a Tablet-Based, Gamified Exercise Application.

Although homebound older adults face high risk for falls, they are unable to utilize community-based fall prevention programs due to their mobility limitations. In this article, we report a feasibility study of a four-session, multicomponent fall prevention program for low-income homebound older adults using pre, post, mixed-method design. The manualized program was delivered by lay coaches who were trained and supervised by a physical therapist. The program also used an iPad-based gamified strength and balance exercise app (called KOKU) that was operable without the need to connect to the internet. Participants (N = 28) in this study were highly receptive to the program and approved all components: psychoeducation, the KOKU app, home-safety checks, safe ambulation training, and medication review. The study showed that a brief, multi-component fall prevention program for homebound older adults is feasible and acceptable. Further research is needed to evaluate its effectiveness.

Impact of COVID-19 'Stay Home, Stay Healthy' Orders on Function among Older Adults Participating in a Community-Based, Behavioral Intervention Study.

Background: Early mitigation orders for COVID-19 halted participation in community-based programs. We examined the early impact of "Stay Home, Stay Healthy" orders on functioning in older adults participating in a behavioral intervention study involving community-based exercise. Methods: A quasi-natural experiment, using mixed methods (n = 39). Participants completed interviews and questionnaires after 3-4 weeks of the Stay Home, Stay Healthy directive. PROMIS-29 outcomes were compared to pre-COVID-19 responses. Results: Participants had a mean age of 74.1 (6.5) years, 79.5% were women, and 20.5% were racial/ethnic minorities. Compared to pre-COVID-19, there was a significant increase in anxiety and decrease in fatigue and social participation. Thematic analysis revealed five main themes related to disruption of daily life, the emotional and physical impact of stay-at-home orders, unexpected positive outcomes, and perspectives on messaging surrounding the pandemic. Conclusions: Efforts to curb the spread of COVID-19 have substantially impacted the lives of older adults participating in community-based exercise.
