Psychometrics of the Physical Resilience Scale in Older Adults Living with Dementia: Proxy Responses

Objectives: The purpose of this study was to determine if proxies can complete the Physical Resilience Scale for older adults living with dementia. Methods: This was a descriptive study using Rasch analysis and baseline data from the Function Focused Care for Acute Care Using the Evidence Integration Triangle trial. The first 240 patients living with dementia were included in this analysis. Results: There was evidence of reliability based on person and item separation index. There was no evidence of Differential Item Functioning (DIF) between genders and a DIF by race on Item 7. Validity was supported based on items fitting the model with the exception of one item, and a significant relationship between physical resilience and pain and function. Discussion: There is some evidence that the Physical Resilience Scale is reliable and valid when completed by proxy reports. Future use should remove one of the items due to redundancy.

The Relationship Between Physical Activity and Limited Range of Motion in the Older Bedridden Patients

Background

The purpose of this study is to examine the association between physical activity and contracture in older patients confined to bed in long-term care (LTC) facilities.

Methods

Patients wore ActiGraph GT3X+ for 8 hours on their wrists, and vector magnitude (VM) counts were obtained as the amount of activity. The passive range of motion (ROM) of joints was measured. The severity of ROM restriction classified, as the tertile value of the reference ROM of each joint, was scored 1-3 points. Spearman's rank correlation coefficients (Rs) were used to measure the association between the VM counts per day and ROM restrictions.

Results

The sample comprised 128 patients with a mean (SD) age of 84.8 (8.8) years. The mean (SD) of VM was 84574.6 (115195.2) per day. ROM restriction was observed in most joints and movement directions. ROMs in all joints and movement directions, except wrist flexion and hip abduction, were significantly correlated with VM. Furthermore, the VM and ROM severity scores showed a significant negative correlation (Rs = -0.582, p < .0001).

Conclusions

A significant correlation between the physical activity and ROM restrictions indicates that a decrease in the amount of physical activity could be one of the causes of contracture.

The association of physical activity and behavioral and psychological symptoms among a sample of hospitalized older adults living with dementia

OBJECTIVES

The aims of this study were to: (1) describe the prevalence of behavioral and psychological symptoms of dementia in hospitalized older adults living with dementia and (2) examine the association of physical activity and behavioral and psychological symptoms of dementia among hospitalized older adults living with dementia, after controlling for covariates.

METHODS

Physical activity was measured using the Physical Activity Survey and behavioral and psychological symptoms of dementia were measured using the Neuropsychiatric Inventory. Descriptive analysis and multiple linear regressions were run using baseline data on 294 older adults with dementia hospitalized on general medical units from an ongoing study entitled Function Focused Care for Acute Care Using the Evidence Integration Triangle.

RESULTS

Participants performed an average of 7.92 (SD = 4.49) of 34 possible activities "in the last 24 h" prior to the Physical Activity Survey administration. A total of 132 participants (45.5%) had at least one behavioral and psychological symptom of dementia. We found that physical activity was not associated with behavioral and psychological symptoms of dementia (b = 0.01; p = 0.56), after controlling for covariates.

CONCLUSIONS

Although this study found no evidence of an association between physical activity and behavioral and psychological symptoms of dementia, evidence of physical activity did not exacerbate these behaviors. Thus, given the benefits of physical activity, it is important to continue to encourage patients living with dementia to engage in activity.

Testing Function Focused Care for Acute Care using the Evidence Integration Triangle: Protocol description

This manuscript provides the protocol for a National Institute of Aging-funded cluster randomized clinical trial that focuses on helping nurses in acute care to engage patients with dementia in physical activity while hospitalized using an approach referred to as function-focused care. Physical activity is defined as bodily movement produced by skeletal muscles resulting in the expenditure of energy and includes functional tasks such as bathing and dressing, leisure activity, ambulation, and moderate and vigorous intensity physical activity such as dancing, bike riding, or walking upstairs. The development of Function Focused Care for Acute Care (FFC-AC) was based on the Social Ecological Model and Social Cognitive Theory and includes four steps: (1) Environment and Policy Assessments; (2) Education; (3) Establishing Patient Goals; and (4) Mentoring and Motivating of Staff (all levels of nursing staff), Patients, and Families. Function-focused care activities include motivating older patients to participate in bed mobility; personal care activities such as bathing, dressing, ambulating as they are able; and other types of physical activities. The integration of the intervention among the nurses on the units is guided by the Evidence Integration Triangle (EIT), which includes the participation of a stakeholder team and practical outcome measures. The intervention is therefore referred to as FFC-AC-EIT. In addition to describing the protocol developed to test the effectiveness and feasibility of FFC-AC-EIT, a description of ways to overcome some of the barriers and challenges that can be encountered with this study is provided.

Measuring the outcomes for aged care residents' participation in physical activity interventions: A systematic review of randomised controlled trials

OBJECTIVES

Lack of physical activity presents substantial health risks to older adults living in residential aged care facilities. The objective of this review was to examine the suitability of physical activity outcome measurement instruments among cognitively sound residents.

METHODS

Search terms were used to explore health, nursing and social science databases to identify applicable English-language research from January 2000 to July 2020.

RESULTS

Sixteen papers met the inclusion criteria. The findings show that a diverse range of outcome measurement instruments have been used to evaluate physical activity intervention effectiveness. Most were found not to be validated for use specifically with residential aged care populations.

CONCLUSIONS

A range of Outcome Measurement Instruments (OMI) appear to effectively measure physical activity intervention outcomes among residential aged care older adults. Results highlighted the need for greater rigour in study design and selection of valid and population-appropriate instruments for use with this population.

Factors That Influence Nurse Staffing Levels in Acute Care Hospital Settings

PURPOSE

To identify which patient and hospital characteristics are related to nurse staffing levels in acute care hospital settings.

DESIGN

A cross-sectional design was used for this study.

METHODS

The sample comprised 1,004 patients across 10 hospitals in the Andalucian Health Care System (southern Spain) in 2015. The sampling was carried out in a stratified, consecutive manner on the basis of (a) hospital size by geographical location, (b) type of hospital unit, and (c) patients' sex and age group. Random criteria were used to select patients based on their user identification in the electronic health record system. The variables were grouped into two categories, patient and hospital characteristics. Multilevel linear regression models (MLMs) with random intercepts were used. Two models were fitted: the first was the null model, which contained no explanatory variables except the intercepts (fixed and random), and the second (explanatory) model included selected independent variables. Independent variables were allowed to enter the explanatory model if their univariate association with the nurse staffing level in the MLM was significant at p < .05.

RESULTS

Two hierarchical levels were established to control variance (patients and hospital). The model variables explained 63.4% of the variance at level 1 (patients) and 71.8% at level 2 (hospital). Statistically significant factors were the type of hospital unit (p = .002), shift (p < .001), and season (p < .001). None of the variables associated with patient characteristics obtained statistical significance in the model.

CONCLUSIONS

Nurse staffing levels were associated with hospital characteristics rather than patient characteristics.

CLINICAL RELEVANCE

This study provides evidence about factors that impact on nurse staffing levels in the settings studied. Further studies should determine the influence of patient characteristics in determining optimal nurse staffing levels.

Racial differences in physical activity in nursing home residents with cognitive impairment

BACKGROUND

Nursing home (NH) residents with moderate-to-severe cognitive impairment experience mostly sedentary lifestyles.

AIM

Previous research has examined racial differences in physical activity (PA) levels in community-dwelling older adults but not in NH residents with cognitive impairment, and the current study aimed to examine these differences.

METHODS

This was a secondary data analysis of baseline data from the Function and Behavior Focused Care Intervention (FBFC) study. The sample included 247 cognitively impaired residents from 12 NHs who wore an ActiGraph to measure PA.

RESULTS

The residents' mean age was 82.6 (SD = 10.1) and had an average MMSE score of 7.8 (SD = 5.0). The sample (N = 247) was 41% African American and 59% White. African American and White residents engaged in only 50.6 and 46.2 min of light- and 1.5 and 1.1 min of moderate-level PA, respectively. Based on a multivariate analysis of covariance (MANCOVA), there was not a statistically significant difference between African American and White residents on combined dependent PA measures [F (8, 237) = 1.067, p = .387, Wilks' Λ = 0.962]. There was a trend that direct care providers subjectively reported that White residents engaged in more PA than their African American counterparts [F(8, 237) = 2.741, p = .09].

CONCLUSIONS

These findings are not consistent with prior research. However, these findings indicate severely low levels of PA in NH residents, regardless of racial group. Future research should prioritize PA interventions that make accommodations for all NH residents, and especially consider their underlying physical comorbidities and cognitive function.

Quantifying physical activity in aged residential care facilities: A structured review

BACKGROUND

Engaging aged residential care (ARC) residents with physical activity (PA) may be a useful strategy to decelerate dependence and disability. It is unclear what volume, intensity and patterns of PA ARC residents participate in. This review aims to synthesize the literature to quantify the volume, intensity and pattern of PA that ARC residents participate in across differing care levels (e.g. low, intermediate, high, mixed), and make recommendations for future research.

METHODS

30 studies of 48,760 yielded were reviewed using systematic review strategies.

RESULTS

Questionnaires and technological tools were used to assess PA, with accelerometers employed in 70% of studies. Overall, studies reported low volumes and intensities of PA across all care levels, and suggested limited variation in patterns of PA (e.g. little day-to-day variation in total PA). There was limited inclusion of people with cognitive impairment, potentially causing representativeness bias. Findings were limited by lack of consistency in methodological approaches and PA outcomes.

DISCUSSION

Based on findings and limitations of current research, we recommend that total volume or low-light intensity PA are more useful interventional outcomes than higher-intensity PA. Researchers also need to consider which methodology and PA outcomes are most useful to quantify PA in ARC residents.

A Cluster Randomized Controlled Trial Testing the Impact of Function and Behavior Focused Care for Nursing Home Residents With Dementia

OBJECTIVE

The purpose of this study was to test the effectiveness of the Function and Behavior Focused Care for the Cognitively Impaired (FBFC-CI) intervention on function, physical activity, and behavioral symptoms among nursing home residents with dementia, and to explore the adoption of the intervention at the facility level.

DESIGN

This study was a clustered, randomized controlled trial with a repeated measures design that was implemented in 12 nursing homes randomized to either treatment (FBFC-CI) or educational control [Function and Behavior Focused Care Education (FBFC-ED)].

SETTING AND PARTICIPANTS

Twelve nursing homes (6 treatment and 6 control) and 336 residents (173 treatment and 163 control) with moderate to severe cognitive impairment.

MEASURES

Outcomes included functional ability (Barthel Index), physical activity (actigraphy and survey), behavioral symptoms (Resistiveness to Care Scale, Cohen-Mansfield Agitation Inventory, Cornell Scale for Depression in Dementia), and psychotropic medication use.

RESULTS

The participants were 82.6 (SD = 10.1) years of age, mostly female, and were moderate to severely cognitively impaired (Mini-Mental State Exam of 7.8, SD = 5.1). There was a significantly greater increase in time spent in total activity (P = .004), moderate activity (P = .012), light activity (P = .002), and a decrease in resistiveness to care (P = .004) in the treatment versus control group at 4 months. There was no change in mood, agitation, and the use of psychotropic medications. There was some evidence of adoption of the intervention at treatment sites.

CONCLUSIONS AND IMPLICATIONS

This study provides some support for the use of the FBFC-CI Intervention to increase time spent in physical activity and decrease resistive behaviors during care commonly noted among nursing home residents with moderate to severe cognitive impairment.

Feasibility, Reliability, and Validity of the MotionWatch 8 to Evaluate Physical Activity Among Older Adults With and Without Cognitive Impairment in Assisted Living Settings

This study tested the feasibility, reliability, and validity of the MotionWatch 8 among assisted living residents with and without cognitive impairment. Data from the Dissemination and Implementation of Function Focused Care in Assisted Living Using the Evidence Integration Triangle study were used. The sample included 781 individuals from 85 facilities with a mean age of 89.48 (SD = 7.43) years. The majority were female (71%), White (97%), and overall (44%) had cognitive impairment. A total of 70% were willing to wear the MotionWatch 8. Reliability was supported as there was no difference in time spent in activity across three consecutive wear days. Validity was based on hypothesis testing, and function was associated with counts of activity at baseline (p = .001) and 4 months (p = .001). Those with cognitive impairment engaged in less physical activity (p = .04). The MotionWatch 8 is a useful option for measuring physical activity in older adults with and without cognitive impairment.

Prevalence and Associated Factors of Physical Activity Among Older Adults Living in Nursing Homes: A Cross-Sectional Study

In many countries, the physical activity level of nursing home residents is low, and the amount of time spent on such behavior has not been quantified in China. In the current study, pedometers were used to measure the physical activity levels of 349 nursing home residents. Daily steps for residents ranged from 5 to 16,773 steps per day, with a median of 1,608 steps per day. Three hundred (85.96%) residents were sedentary, 16 (4.6%) were low active, and 33 (9.5%) were physically active. Factors such as the living conditions of the nursing home, younger age, lower body mass index, higher educational level, marriage, higher pension, and greater family support all led to a higher physical activity level among residents. Regarding sedentary level, male residents were more active than female residents. The physical activity level of nursing home residents in China is lower than the current World Health Organization standard. [Journal of Gerontological Nursing, 46(10), 19-26.].

The Impact of Physical Activity and Function on Falls in Assisted Living Residents

The purpose of this study was to describe physical activity and function of older adults in assisted living communities and test the association between moderate and vigorous activity and falls. This study used baseline data from 393 participants from the first two cohorts in the Function-Focused Care in Assisted Living Using the Evidence Integration Triangle study. The majority of participants were female (N = 276, 70%) and White (N = 383, 97%) with a mean age of 87 years (SD = 7). Controlling for age, cognition, gender, setting, and function, the time spent in moderate or vigorous levels of physical activity was associated with having a fall in the prior 4 months. Those who engaged in more moderate physical activity were 0.6% less likely to have a fall (OR = 0.994, Wald statistic = 5.54, p = .02), and those who engaged in more vigorous activity were 2% less likely to have a fall (OR = 0.980, Wald statistic = 3.88, p = .05).

Physical Function, Relocation, and Mortality Outcomes in Residential Care and Assisted Living Residents

Objective: This study aimed to identify predictors of 6-month physical function and 12-month relocation or death in 272 residents of 34 residential care/assisted communities. Method: Measures collected at baseline, 6, and 12 months included health and demographic characteristics; self-reported pain, fatigue, and depressive symptoms; exercise self-efficacy, barriers, and expectations; attitudes on aging; performance-based physical function and physical activity; and community demographics, programs, and policies. GLIMMIX procedures for regression analyses with community as a random effect were run. Results: Better baseline physical function and grip strength, female sex, and residential care community predicted better 6-month physical function. At 12 months, 25.6% had relocated or died. The odds of 12-month relocation or death for 1-point increase in physical function score was 0.84 and for 1-point increase in depression score was 1.16. Discussion: Targets to promote longer tenure in residential care/assisted living include programs to ameliorate functional decline and depression screening and treatment.

Attributions for physical activity in very old adults: predicting everyday physical activity and mortality risk

OBJECTIVES

Although physical activity is recognised as a health-promoting behaviour for older adults, notable barriers exist that may reduce physical activity in this age group. Limited research has explored causal beliefs (attributions) as a barrier to physical activity. Our study assessed associations between older adults' attributions about physical activity and objective health outcomes.

METHODS

We examined the role of attributions as a predictor of everyday physical activity (EPA) and subsequent mortality risk over a 10-year period (2006-2016) in a sample of older adults (M_age = 87, N = 261).

RESULTS

OLS and Cox proportional hazard regression analyses revealed older adults who endorsed more internal and uncontrollable attributions for limited activity (physical incapacity) when feeling unwell had lower subsequent EPA (β = -0.18), and higher 10-year mortality risk (HR = 1.46). Other attributions with different dimensional properties (e.g. internal and controllable) were not associated with EPA or mortality.

DISCUSSION

Findings suggest that causal beliefs older adults have about their physical activity can influence their future behaviour and longevity. Psychological treatments designed to discourage maladaptive attributional thinking for older populations who face barriers to physical activity may be an important avenue for future research.

Differences Between Moderate to Severely Cognitively Impaired Fallers Versus Nonfallers in Nursing Homes

INTRODUCTION

The purpose of this study was to test differences in psychotropic medication, function, physical activity, agitation, resistiveness to care, comorbidities, and depression among moderate to severely cognitively impaired nursing home residents who were fallers versus nonfallers.

METHODS

This was a secondary data analysis using baseline data from a randomized controlled trial testing the Function and Behavior Focused Care intervention across 12 nursing homes. The sample included 336 older adults, the majority of whom were female and white.

RESULTS

There was a significant difference in the total number of comorbidities, agitation, the total number of psychotropic medications, depressive symptoms, and physical activity between those who fell and those who did not fall (Pillai-Bartlett trace = 4.91; P < .001).

DISCUSSION

Findings support prior work except with regard to medication use, cognition, and function. Due to inconsistent findings, additional research is recommended particularly with regard to the use of specific drug groups and medications.

Testing the evidence integration triangle for implementation of interventions to manage behavioral and psychological symptoms associated with dementia: Protocol for a pragmatic trial

Behavioral and psychological symptoms of dementia (BPSD) include aggression, agitation, resistiveness to care, depression, anxiety, apathy, and hallucinations. BPSD are common in nursing home residents and can be ameliorated using person-centered approaches. Despite regulatory requirements, less than 2% of nursing homes consistently implement person-centered behavioral approaches. In a National Institute of Nursing Research-funded research protocol, we are implementing a pragmatic cluster randomized clinical trial designed to enable staff in nursing homes to reduce BPSD using behavioral approaches while optimizing function, preventing adverse events, and improving quality of life of residents. The implementation is based on use of the Evidence Integration Triangle (EIT), a parsimonious, community-engaged participatory framework that is well suited to the complexity and variability in the nursing home environment. A total of 50 nursing home communities will be randomized to EIT-4-BPSD or education only. Primary Aim 1 is to determine if communities exposed to EIT-4-BPSD demonstrate evidence of implementation evaluated by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) criteria. Primary Aim 2 is to evaluate the feasibility, utility, and cost of the EIT approach in EIT-4-BPSD communities.

Feasibility and Efficacy of Function-Focused Care for Orthopedic Trauma Patients

To overcome challenges associated with optimizing function and physical activity among hospitalized older adults, we developed function-focused care for acute care (FFC-AC). The purpose of this study was to test the feasibility and preliminary effectiveness of this intervention. We hypothesized that hospitalized trauma patients exposed to FFC-AC would (1) maintain or improve function, spend more time in physical activity, and have fewer adverse events between admission and discharge; and (2) maintain or improve function, have less fear of falling, fewer depressive symptoms, less pain, be more physically resilient, and be less likely to experience adverse events at 1 month postdischarge compared with those exposed to FFC-education only (EO). FFC-AC was implemented by a research function-focused care nurse who worked on the participating units for 20 hr a week for 16 months to implement the three components of FFC-AC. The sample included 89 older orthopedic trauma patients the majority of whom were female (N = 59, 66%), white (N = 82, 92%), and not married (N = 53, 59%). At discharge and/or 30 days postdischarge, participants in the treatment site showed greater improvement in function, less fear of falling, and better physical resilience when compared with those in the FFC-EO site. Future research is needed to continue to work on engaging staff in function-focused care approaches and optimizing the hospital environment and policies to support nurses in this type of care approach.

Factors that Influence Physical Activity among Residents in Assisted Living

The purpose of this study was to examine factors that influence physical activity among residents in assisted living. This was a secondary data analysis using baseline data from a function-focused care intervention study including 171 residents from 4 assisted living facilities. Using structural equation modeling, we found that mood, satisfaction with staff and activities, and social support for exercise were directly associated with time spent in physical activity. Gender, cognition, depression, and comorbidities were indirectly associated with physical activity and accounted for 13% of the total variance in physical activity. Implications for future research and social work practice are presented.

Reliability and Validity of the Resistiveness to Care Scale Among Cognitively Impaired Older Adults

BACKGROUND

Resistiveness to care is behavior that prevents or interferes with caregivers' performing or assisting with activities of daily living and puts residents at risk for inappropriate use of antipsychotic drugs, other restraining interventions, social isolation, and physical abuse. The purpose of this study was to establish the psychometric properties of a previously developed Resistiveness to Care measure.

PROCEDURES

This was a descriptive study using baseline data from an ongoing randomized controlled trial testing a Function and Behavior Focused Care (FBFC) intervention. Residents were eligible to participate if they were 55 years of age or older, had a Mini-Mental State Exam (MMSE) score of 15 or less, and were not enrolled in hospice or admitted for subacute care. Descriptive information included age, race, gender, cognitive status, and marital status. In addition to the Resistance to Care Scale, the Barthel Index, the Physical Activity Survey in Long Term Care (PAS-LTC), and the Cohen-Mansfield Agitation Inventory (CMAI) were completed. Psychometric testing was done using Rasch analysis and the Winsteps statistical program.

MAIN FINDINGS

The participants were moderate to severely cognitively impaired (MMSE of 7.23), functionally dependent (Barthel Index 47.31, SD 27.59), and engaged in only 134.17 (SD = 207.32) minutes of physical activity daily. Reliability was supported based on a Cronbach alpha of 0.84 and the DIF analysis, as there was no difference in function of the items between male and female participants. Validity was supported as all items fit the measurement model based on INFIT and OUTFIT statistics.

CONCLUSIONS

The findings support the reliability and validity of the Resistiveness to Care Scale for use with older adults with dementia in nursing home settings. Future work with the measure may benefit from the addition of items that are easier to endorse with regard to resistiveness to care (shutting eyes or spitting out food may be useful additions).

Function Focused Care for Assisted Living Residents With Dementia

PURPOSE OF THE STUDY

Assisted living (AL) residents with dementia require assistance with activities of daily living, encounter limited opportunities to engage in physical activity, and often exhibit challenging behavioral symptoms. The Function Focused Care Intervention for the Cognitively Impaired (FFC-CI) teaches and motivates direct care workers (DCWs) to engage residents with dementia in activities that optimize function and activity while minimizing behavioral symptoms. The purpose of this study was to test the impact of FFC-CI on function, physical activity, behavior, and falls.

DESIGN AND METHODS

A cluster-randomized trial included 96 residents with dementia and 76 DCWs from 4 ALs. Generalized estimating equations were used to evaluate outcomes at 3 and 6 months.

RESULTS

There were no treatment by time differences with regard to resident behavior, mood, counts of physical activity based on actigraphy, falls, and function. There were significant increases in physical activity based on kilocalories burned (p = .001), time spent in physical activity based on survey results (p = .001), and time spent in repetitive behaviors, such as wandering (p = .01) among the control group over time. There were no treatment by time differences with regard to DCW beliefs, knowledge, or performance of FFC, except for less decline in job satisfaction among the treatment group (p = .002). Treatment fidelity with regard to delivery and receipt were poor due to high staff attrition in the treatment group (46% vs. 16%) and limited site support.

IMPLICATIONS

The findings from this study can be used to adapt future FFC intervention studies to improve treatment fidelity and optimize intervention efficacy.

Optimizing physical activity among older adults post trauma: Overcoming system and patient challenges

BACKGROUND

By 2050 it is anticipated that close to half (40%) of all trauma patients will be over the age of 65. Recovery for these individuals is more complicated than among younger individuals. Early mobilization has been shown to improve outcomes. Unfortunately, there are many challenges to early mobilization. The Function Focused Care Intervention was developed to overcome these challenges.

PURPOSE

The purpose of this paper was to describe the initial recruitment of the first 25 participants and delineate the challenges and successes associated with implementation of this intervention.

RESULTS

Overall recruitment rates were consistent with other studies and the intervention was implemented as intended. Most patients were female, white and on average 79 years of age. Optimizing physical activity of patients was a low priority for the nurses with patient safety taking precedence. Patients spent most of the time in bed. Age, depression and tethering were the only factors that were associated with physical activity and functional outcomes of patients.

CONCLUSION

Ongoing work is needed to keep patients physically active in the immediate post trauma recovery period.

Optimizing Eating Performance for Long-Term Care Residents With Dementia: Testing the Impact of Function-Focused Care for Cognitively Impaired

OBJECTIVES

The objective of this study was to evaluate the impact of a well-developed theory-based function-focused care for cognitively impaired (FFC-CI) intervention on eating performance among long-term care (LTC) residents with moderate-to-severe cognitive impairment.

DESIGN

A secondary analysis of longitudinal data from 2 cluster-randomized controlled trials that originally tested the impact of FFC-CI on all function and physical activities.

PARTICIPANTS AND SETTING

Participants were 199 residents with moderate-to-severe cognitive impairment from 4 nursing homes and 4 assisted living facilities.

MEASUREMENTS

Data at baseline, and 3 and 6 months were used. Resident outcome data used in this analysis included eating performance conceptualized using the single self-care "feeding" item in the Barthel Index, cognitive function by Mini-Mental State Examination, sitting balance conceptualized using the single "chair sit-sitting balance" item in the Tinetti Gait and Balance scale, physical capability by Physical Capability Scale, depression by Cornell Scale for Depression in Dementia, and agitation by Cohen-Mansfield Agitation Inventory (short form).

RESULTS

At baseline, almost one-third (32.2%) of the 199 residents needed help with eating. There was no significant change with regard to eating performance over time in both groups, and no significant treatment by time difference between groups in eating performance (P = .195).

CONCLUSION

Current findings support a need to revise the FFC-CI to better address eating performance. Future work may benefit from a stronger focus on eating performance rather than the more commonly addressed functional tasks, such as bathing, dressing, and ambulation. In addition, the inclusion of a more heterogeneous group of LTC residents with regard to eating performance is needed to test the impact of the revised approach on eating performance.

The Self-Efficacy for Functional Abilities Scale for older adults in long-term care: two-level exploratory and confirmatory factor analysis

BACKGROUND AND PURPOSE

This study examines the underlying factor structure of the Self-Efficacy for Functional Abilities (SEFA) scale among older adults in long-term care settings.

METHODS

A secondary analysis of SEFA data for 568 residents in 16 long-term care facilities was applied. The sample was randomly split into 2 subsamples. A 2-level exploratory and confirmatory factor analysis adjusting for clustering effect of facilities was used to identify and determine the factor structures respectively.

RESULTS

There were 1- and 2-factor models that were identified. Both models demonstrated acceptably mixed model fit. The 2-factor model had poor discriminant validity with high correlation between factors (r = .92, p < .001). The single-factor model was considered valid with moderate correlation with function (r = .301, p < .001).

CONCLUSIONS

The SEFA scale demonstrated a unidimensional construct among older adults in long-term care settings. Future testing is needed among other older adult populations.

Basic Physical Capability Scale: Psychometric Testing With Cognitively Impaired Older Adults

The purpose of this study was to evaluate the reliability and validity of the Basic Physical Capability Scale when used with older adults having moderate to severe cognitive impairment and consider the utility of the measure in establishing function-focused care (FFC) goals for these individuals. The study was a secondary data analysis using data from 2 intervention studies testing FFC interventions in older adults with moderate to severe cognitive impairment in nursing homes and assisted living settings. Participants included 96 recruited from 4 assisted living facilities and 103 older adults from 4 nursing homes. There was support for validity of the measure based on construct validity and hypothesis testing, internal consistency (Cronbach's α of .79), and utility of the measure. Recommendations are provided for additional items that might help better differentiate individuals with moderate to severe cognitive impairment who are particularly high or low in basic physical capability.

Optimizing function and physical activity among nursing home residents with dementia: testing the impact of function-focused care

PURPOSE OF THE STUDY

The purpose of this study was to test the impact of Function-Focused Care for the Cognitively Impaired Intervention on nursing home residents with dementia and the nursing assistants who care for them.

DESIGN AND METHODS

This was a cluster-randomized controlled trial using repeated measures. A total of 103 cognitively impaired residents and 77 nursing assistants were recruited from four nursing homes. For residents, outcome measures included function, physical activity (survey and actigraphy), mood, behavior, and adverse events (falls and hospitalization). Main outcome measures for nursing assistants included knowledge, beliefs, and performance of function focused care.

RESULTS

There were significant improvements in the amount and intensity of physical activity (by survey and actigraphy) and physical function in the treatment group. In addition, there was a significant decrease in the number of residents who fell during the treatment period with those in the treatment sites having fewer falls (28% vs. 50% in the control group). Nursing assistants were also observed to be providing a greater percentage of function focused care during resident care interactions in the treatment group at 6 months following the completion of baseline measures.

IMPLICATIONS

This study provides some evidence that nursing home residents with severe cognitive impairment can safely and successfully be engaged in physical and functional activities.

Validity of motor impairment scale in long-term care insurance system of Korea

OBJECTIVE

To validate the Motor Impairment Scale (MIS) of the Korean long-term care insurance (LTCI) system by comparing with the service time offered for aiding activities of daily living (ADL) and the ADL score.

METHODS

A total of 407 elderly subjects without dementia who had used LTCI services were included in this study. Spearman correlations and multivariate linear regression models were employed to determine the relationship of the upper and lower limb MIS (U-MIS and L-MIS, respectively) to the service time and ADL. Stratified analyses for the facility group (n=121) and the domiciliary group (n=286) were performed.

RESULTS

There were significant differences in characteristics between facility group and domiciliary group. The MIS was significantly correlated with service time in facility group (Spearman p=0.41 for U-MIS, Spearman p=0.40 for L-MIS). After adjusting for age, sex, and cognition score, U-MIS was an independent predictor for service time in facility group (p=0.04). In domiciliary group, no significant correlation was found between the MIS and service time. The MIS correlated with all of the ADL items and total ADL score in both groups. After adjusting for other factors including age, sex, and cognitive score, U-MIS and L-MIS were independent variables for explaining the total ADL score in both groups.

CONCLUSION

The validity of the MIS as an evaluation tool in the physically-disabled elderly is higher in facility group than in domiciliary group. As an easy, objective, and simple method, MIS can be a useful tool in the LTCI system of Korea.

Patient-reported physical activity questionnaires: a systematic review of content and format

Background

Many patients with chronic illness are limited in their physical activities. This systematic review evaluates the content and format of patient-reported outcome (PRO) questionnaires that measure physical activity in elderly and chronically ill populations.

Methods

Questionnaires were identified by a systematic literature search of electronic databases (Medline, Embase, PsychINFO & CINAHL), hand searches (reference sections and PROQOLID database) and expert input. A qualitative analysis was conducted to assess the content and format of the questionnaires and a Venn diagram was produced to illustrate this. Each stage of the review process was conducted by at least two independent reviewers.

Results

104 questionnaires fulfilled our criteria. From these, 182 physical activity domains and 1965 items were extracted. Initial qualitative analysis of the domains found 11 categories. Further synthesis of the domains found 4 broad categories: 'physical activity related to general activities and mobility', 'physical activity related to activities of daily living', 'physical activity related to work, social or leisure time activities', and '(disease-specific) symptoms related to physical activity'. The Venn diagram showed that no questionnaires covered all 4 categories and that the '(disease-specific) symptoms related to physical activity' category was often not combined with the other categories.

Conclusions

A large number of questionnaires with a broad range of physical activity content were identified. Although the content could be broadly organised, there was no consensus on the content and format of physical activity PRO questionnaires in elderly and chronically ill populations. Nevertheless, this systematic review will help investigators to select a physical activity PRO questionnaire that best serves their research question and context.

Physical activity monitoring by use of accelerometer-based body-worn sensors in older adults: a systematic literature review of current knowledge and applications

OBJECTIVES

To systematically review the literature on physical activity variables derived from body-worn sensors during long term monitoring in healthy and in-care older adults.

METHODS

Using pre-designed inclusion and exclusion criteria, a PubMed search strategy was designed to trace relevant reports of studies. Last search date was March 8, 2011.

STUDY SELECTION

Studies that included persons with mean or median age of >65 years, used accelerometer-based body-worn sensors with a monitoring length of >24h, and reported values on physical activity in the samples assessed.

RESULTS

1403 abstracts were revealed and 134 full-text papers included in the final review. A variety of variables derived from activity counts or recognition of performed activities were reported in healthy older adults as well as in in-care older adults. Three variables were possible to compare across studies, level of Energy Expenditure in kcal per day and activity recognition in terms of total time in walking and total activity. However, physical activity measured by these variables demonstrated large variation between studies and did not distinguish activity between healthy and in-care samples.

CONCLUSION

There is a rich variety in methods used for data collection and analysis as well as in reported variables. Different aspects of physical activity can be described, but the variety makes it challenging to compare across studies. There is an urgent need for developing consensus on activity monitoring protocols and which variables to report.

Satisfaction with assisted living: the unexplored role of physical activity

In the ongoing Interdisciplinary Nursing Quality Research Initiative Program study, we are testing the impact of Function-Focused Care, which is an approach to care in which we work with assisted living (AL) residents and staff to optimize the functional and physical activities of residents during daily activity. The purpose of this article is to evaluate life satisfaction of AL residents with a focus on the impact of physical activity. In a sample of 171 older adults from 4 ALs, it was found that depression, social support from friends and experts, time in caregiving, and fear of falling all had a significant relationship with life satisfaction in AL. Physical activity was not related to life satisfaction in this study. Ongoing research is necessary to explore whether changing attitudes about physical activity among older adults and increasing social support related to physical activity can improve life satisfaction.

Perceptions and performance of function and physical activity in assisted living communities

OBJECTIVE

The purpose of this study was to describe residents' self-efficacy and outcome expectations with regard to function and physical activity (PA); to measure functional performance and time in PA; to evaluate the fit between the resident and the environment; and to evaluate knowledge, beliefs, and care behaviors of nursing assistants (NAs) in 4 different assisted living (AL) communities.

DESIGN

This was a descriptive study using baseline data from an ongoing intervention study, Testing the Impact of a Function Focused Care Intervention, Res-Care-AL.

SETTING

Four assisted living communities in Maryland.

PARTICIPANTS

A total of 171 residents and 96 NAs consented, passed eligibility, and were included in this study.

MEASUREMENTS

Descriptive data were obtained from NAs and residents. Resident data also included self-efficacy and outcome expectations associated with functional tasks and exercise, social support for exercise, and subjective and objective information about function and physical activity. NA data included self-efficacy and outcome expectations, knowledge, and performance of function-focused care.

RESULTS

Residents were mostly female, white, and widowed; needed some assistance with activities of daily living; and engaged in very little PA based on subjective and objective reports. NAs were mostly female and black, had more than a decade of nursing experience, strong confidence but limited knowledge of function-focused care, and performed this care in 76% of observed care interactions. There were no site-specific differences among NAs with regard to beliefs, knowledge, or performance of function-focused care. There were site-specific differences in residents with regard to self-efficacy for functional ability; functional performance; social supports for exercise from experts; and from family, person-environment fit, and PA based on subjective surveys. There were no differences noted based on actigraphy.

CONCLUSION

Residents in AL communities engage in very limited amounts of PA and staff in these sites could benefit from ongoing education about how to increase PA among residents and help them adhere to current guidelines for PA so as to optimize overall health status.

Differential determinants of men's and women's everyday physical activity in later life

OBJECTIVES

The present study of a representative sample of older adults quantified everyday physical activity (EPA) by having participants wear actigraphs. Our objectives were to examine whether poor health may partly explain why older adults become less physically active with advancing age and whether gender might moderate the extent to which health status predicts EPA.

METHODS

We performed multiple regression analyses on a sample of older, community-dwelling adults (aged 80-98 years, N = 198; women = 63.1%).

RESULTS

The results imply that age-related declines in EPA may be partially accounted for by health (in men) and by living arrangements (in women).

DISCUSSION

We consider reasons why poorer health might erode EPA for men (but not women) and why living alone might erode EPA for women (but not men).
