RESUMO

In collaboration with stakeholders, we conducted a systematic review of psychometric evidence for self-report tools measuring the perspective of family caregivers of nursing home residents with dementia. Our rationale for this review was based on evidence that nonpharmacological interventions can ameliorate dementia symptoms in nursing home residents. Such interventions require caregiver participation, which is influenced by perspectives. Yet, no existing tool measures the multidomain caregiver perspective. Our review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. The final sample included 42 articles describing 33 tools measuring domains of nursing home dementia care such as behavioral and psychological symptoms of dementia, resident quality of life, dementia-specific knowledge, communication, and medication use. We uncovered evidence gaps for tools measuring dementia-specific knowledge, communication, and medication use, all of which were important to our stakeholders. Future research should focus on development of psychometrically sound tools in alignment with the multidomain caregiver perspective.

RESUMO

We developed and evaluated the psychometric properties of the Columbia Behavior Scale for Dementia (CBS-8), a rapid instrument that assesses positive symptoms, to enhance behavioral and psychological symptoms of dementia (BPSD) assessment and treatment in long-term care. Psychometric analyses were performed on CBS-8 data from residents (N = 350, age ≥50 years) in 47 Maryland long-term care facilities referred for neurocognitive and mood evaluation. The CBS-8 demonstrated acceptable internal consistency (α = 0.78) and strong interrater reliability (intraclass correlation coefficient = 1.00). CBS-8 scores were correlated with greater cognitive impairment severity (r = -0.34). The diagnosis of dementia with behavioral disturbance had higher CBS-8 scores than other dementia types (e.g., vascular, unspecified) (p < 0.001, η2 = 0.40). Three CBS-8 factors-motor disinhibition, aggression, and psychosis-explained 65% of the variance in overall BPSD. The CBS-8 could enhance BPSD tracking and treatment, strengthen interdisciplinary collaboration, and aid nursing homes in meeting regulations on unnecessary medication use.

RESUMO

BACKGROUND: Older adults are at high risk for developing serious somatic and psychological symptoms associated with COVID-19. Currently available instruments may not be sensitive to the concerns about COVID-19 in postacute and long-term care and their applications in telehealth remain to be clarified. OBJECTIVE: We investigated the psychometric properties of the Mood-5 Scale (M5) as a rapid self-assessment of the COVID-19 psychological burden among postacute and long-term care residents. METHODS: Residents (N=131), aged 50 years and above, from 20 postacute and long-term care facilities in Maryland, USA, were evaluated in-person or via telehealth (43/131, 32.8%) across a 4-week period (May 11 to June 5, 2020) during the COVID-19 pandemic. The COVID-19 psychological burden experienced by the residents was rated by geriatric psychologists who independently reviewed their clinical documentation. Psychometric analyses were performed on the M5 in relation to psychological tests, COVID-19 psychological burden, and diagnostic data collected during the evaluation. RESULTS: The M5 demonstrated acceptable internal consistency (Cronbach α=.77). M5 scores were not confounded by demographic variables or telehealth administration (P>.08). Convergent validity for the M5 was established via positive associations with anxiety (r=0.56, P<.001) and depressive (r=0.49, P<.001) symptoms. An M5 cutoff score of 3 demonstrated strong sensitivity (0.92) and adequate specificity (0.75) for identifying COVID-19 psychological distress among postacute and long-term care residents (area under the curve of 0.89, positive predictive value=0.79, negative predictive value=0.91). CONCLUSIONS: The M5 is a reliable and valid tool for self-assessment of mood that can help identify postacute and long-term care residents with significant psychological burden associated with COVID-19. It can be completed in less than 1 minute and is appropriate for use in both in-person and virtual visits.

RESUMO

BACKGROUND: Barriers to the early detection of mild cognitive impairment (MCI) and dementia can delay diagnosis and treatment. myMemCheck® was developed as a rapid free cognitive self-assessment tool that can be completed at home to identify older adults that would benefit from a more comprehensive cognitive evaluation. OBJECTIVE: Two prospective cross-sectional studies were conducted to examine the psychometric properties and clinical utility of myMemCheck®. METHODS: In Study 1, participants were independent living residents referred to an outpatient memory clinic (N = 59); older adults in the community and post-acute nursing home residents (N = 357) comprised Study 2. RESULTS: Psychometric analyses were performed on cognitive and psychological testing data, including myMemCheck®. myMemCheck® evidenced adequate reliability and strong construct validity. Receiver operating characteristic analysis evidenced an optional myMemCheck® cut score for identifying older adults at risk for MCI or dementia. myMemCheck® explained 25% of cognitive status beyond basic patient information. CONCLUSIONS: myMemCheck® may help fast-track the diagnostic process, facilitate appropriate referrals for cognitive and neuropsychological evaluation, reduce assessment burden in health care and prevent negative outcomes associated with undetected cognitive impairment.

RESUMO

The objective of the current study was to investigate possible racial disparities in dementia among long-term care (LTC) residents. Participants were 1,239 residents (age ≥50) from 61 nursing home and assisted living facilities in Maryland. Retrospective analysis was performed to compare Brief Cognitive Assessment Tool (BCAT®) scores between African American and White participants. African American participants had 1.43 times greater odds of dementia and 1.86 times greater odds of severe-stage dementia than White residents. African American residents were significantly younger than their White peers by approximately 9 years within mild-moderate dementia levels and by 5 years at the severe stage. The rate of cognitive decline did not significantly differ by race despite a more negative curvilinear relationship between BCAT scores and age for African American participants than White participants. Implications of these findings are discussed for successful resident-centered care in LTC settings as well as for care transitions. [Research in Gerontological Nursing, xx(x), xx-xx.].

RESUMO

BACKGROUND AND OBJECTIVES: Diagnostic criteria for mild cognitive impairment (MCI) exclude functional deficits, yet recent studies suggest that older adults with MCI can exhibit impairment in instrumental activities of daily living (IADL). To assist health care providers in detecting functional vulnerabilities that often precipitate loss of independence, we: (a) compared IADL dependence in MCI to older adults without cognitive impairment and those with dementia, (b) estimated the odds of dependence on specific IADLs in MCI, and (c) investigated the differential contributions of memory and executive functions to IADL dependence. RESEARCH DESIGN AND METHODS: Participants were older adults (Mage = 77.58 ± 11.05) in Maryland, USA (N = 512) community and postacute rehabilitation settings. Analysis was performed on Brief Cognitive Assessment Tool (BCAT) and the Functional Activities Questionnaire (FAQ) data that assessed participants' cognitive functioning and IADL dependence, respectively. RESULTS: 61.04% of participants with MCI were dependent on one or more IADLs. MCI was associated with significantly greater odds of dependence than normal cognition on 7 of the 10 IADLs (odds ratios = 2.62-4.66). Impairment in memory and executive functions significantly predicted IADL dependence (18.52% of variance beyond demographics); executive functions were the stronger predictor, particularly for complex finances, complex cooking, and remembering events. DISCUSSION AND IMPLICATIONS: IADL dependence can occur even in MCI. Testing suggestive of MCI should alert clinicians to further investigate the older adult's profile of cognitive and functional limitations to highlight targets for caregiver support and promote independence by "right-sizing" community or facility resources.

RESUMO

OBJECTIVES: The clinical assessment of older adults' judgment is important for mitigating safety risks that often precipitate loss of independence. Our national survey of geriatric healthcare providers (N = 496; M years of experience = 17.11 ± 10.60) indicated that formal judgment tests are underutilized in clinical practice. We developed the Verbal Test of Practical Judgment (VPJ) as a new test of judgment for older adults intended to identify difficulty performing instrumental activities of daily living (IADL). METHOD: In two prospective studies, participants were long-term care facility residents (age ≥ 50) in Maryland, USA (Study 1, N = 51; Study 2, N = 110) referred to licensed psychologists for neuro-cognitive and mood evaluation by facility attending physicians. Psychometric analyses were performed to examine the construct validity of the VPJ. RESULTS: The VPJ evidenced adequate reliability and strong construct validity across both studies. Receiver operating characteristic analysis yielded an optimal VPJ cut score for identifying impaired judgment. The VPJ significantly predicted IADL performance beyond clinician and participant ratings. CONCLUSION: The VPJ appears to be a valid tool for assessing judgment among older adults with suspected cognitive impairment. VPJ score inferences can inform clinicians on the odds of requiring assistance for specific IADLs.

RESUMO

INTRODUCTION: The prevalence of cognitive, sensory, and physical impairments is expected to grow alongside increasing life expectancy. These chronic conditions pose challenges for geriatric assessment. We examined whether Brief Cognitive Assessment Tool (BCAT) modifications to accommodate visual and motor limitations would retain strong validity for identifying mild cognitive impairment (MCI) and dementia. METHOD: Psychometric analyses were performed on archival data (N = 458) from community-dwelling older adults and residents of assisted living facilities and nursing homes in Maryland, USA (age ≥ 50 years). Participants completed a brief testing battery, including the BCAT, and were assigned a cognitive diagnosis (normal cognition, MCI, mild dementia, moderate dementia, severe dementia) by licensed clinical psychologists. RESULTS: Receiver operator characteristic curve analyses evidenced excellent diagnostic validity of BCAT modification cutoffs for identifying the cognitive categories. Contextual memory and executive control factors, which explained over 80% of variance in cognitive diagnoses, may account for the preservation of validity despite BCAT modifications. CONCLUSIONS: The results indicate strong psychometric evidence for the BCAT modifications and provide cutoffs for identifying MCI and staging dementia. For clinicians, the score guidelines are preferable to the guesswork involved with adjusting cutoffs to accommodate visual and motor limitations.

RESUMO

We describe the development and validation of The Brief Cognitive Impairment Scale (BCIS), a cognitive screening instrument designed for persons with severe-stage dementia. Psychometric analyses were performed on neuropsychological data from long-term care residents (N = 247) who completed a brief battery of tests, including the BCIS. A principle component analysis yielded three factors that provide insight into how persons with severe dementia cognitively process information and may tolerate specific aspects of social stimulation, such as during personal care. A BCIS cut score can be used to identify severe dementia with a sensitivity of .82, a specificity of .84, and an area under the curve of .89. It may be used by clinicians or caregivers when advanced dementia is suspected, as an alternative to measures with suspected floor effects, when residents cannot tolerate more demanding assessment tools, and as part of non-pharmacologic treatment plans for behavior disturbances associated with dementia.

RESUMO

Background/Study Context: Whereas computer-assisted cognitive rehabilitation (CR) programs show promise as tools for improving cognition in certain populations, there is not a consensus regarding their efficacy. This study focuses on restorative CR, a treatment designed to improve cognitive functioning affected by progressive brain changes due to disease or aging, through computer-assisted cognitive exercises. The purpose of this study was to investigate the efficacy of a computer-assisted restorative CR intervention for improving cognitive functioning in older rehabilitation patients with relatively mild cognitive deficits. METHODS: Older adult residents in a Maryland retirement community (N = 43) who met inclusion criteria were assigned to either the CR treatment or the control group. Treatment group participants completed 3 weeks (nine sessions) of Memory Match, an online CR module designed to improve attention and visual memory, whereas the control group did not complete the CR program after the baseline assessment. Analyses were based on the 38 (n = 20 treatment, n = 18 control) participants (mean age = 78.08 ± 10.31) who completed the post-assessment Brief Cognitive Assessment Tool (BCAT) and a self-rating inventory (SRI) of cognitive ability. RESULTS: Treatment group participants who received the CR treatment obtained significantly higher BCAT scores (medium to large effect size) at post-assessment than control group participants over the same period. Additional evidence for the efficacy of the CR program was found by comparing responses on a SRI of cognitive ability between the two groups. CONCLUSION: The authors discuss the merits and shortcoming of this pilot study, the utility of the CR program for older rehabilitation patients with relatively mild cognitive deficits, and ideas for future research.

RESUMO

Purpose of the Study: Engagement in meaningful activities is associated with positive outcomes for persons with dementia, yet studies demonstrating quantitative evidence for which activities can be considered meaningful are lacking. We investigated MemPics™, a program designed to promote meaningful activity for individuals with dementia through engagement and cognitive stimulation. It was compared with other recreation activities offered in U.S. long-term care facilities to determine whether MemPics™ was rated as having more meaningful activity from both the perspectives of participants and recreation staff. Design and Methods: Long-term care residents with mild to moderate dementia that met eligibility criteria were randomly assigned to an activity group (treatment, control). Participants completed 2 sessions of either the experimental or control group activity with facility recreation staff. Both participants and staff rated each activity in terms of meaningfulness following each session. Results: Of the enrolled participants (N = 126), study analyses were based on the 94 participants (n = 48 treatment and n = 46 control; M age = 82.98±9.63) who completed the activity sessions. Compared to the control group activities, MemPics™ had significantly higher participant and staff ratings of meaningfulness. Scores between the 2 rater types were significantly different, with staff reporting higher meaningful activity than participants. Further support for MemPics™ was found in exit survey responses from participating staff. Implications: We discuss the merits and shortcoming of this study, the utility of MemPics™ for providing meaningful engagement in long-term care residents with mild to moderate dementia, and ideas for future research.

RESUMO

Reducing off-label antipsychotic medication use for behavioral and psychological symptoms of dementia (BPSD) in nursing home residents has been a centerpiece of government regulation, but without insight into utilization differences based on resident and facility characteristics. To examine whether resident and facility characteristics can predict off-label antipsychotic medication treatment for BPSD, residents prescribed antipsychotic medication (N = 216) from 17 Maryland nursing facilities were randomly selected. Based on physician diagnoses, 59.7% of participants were taking off-label antipsychotic medications for BPSD. Hierarchical logistic regression results suggest that dementia level (indicated by Brief Cognitive Assessment Tool scores) and age, but not facility characteristics, significantly predict greater likelihood of using off-label antipsychotic medications for BPSD. Having moderate-severe dementia was associated with more than a four-fold increase in off-label antipsychotic medication use for BPSD. Off-label use of antipsychotic medications for BPSD remains high, especially for older nursing home residents with more severe dementia, indicating that more targeted reduction approaches are needed.

RESUMO

We compared the accuracy of the Brief Cognitive Assessment Tool-Short Form (BCAT-SF) and AD8 in identifying mild cognitive impairment (MCI) and dementia among long-term care residents. Psychometric analyses of 357 long-term care residents (n = 228, nursing home; n = 129, assisted living) in Maryland referred for neuropsychological evaluation evidenced robust internal consistency reliability and construct validity for the BCAT-SF. Furthermore, hierarchical logistic regression and receiver operating characteristic curve analyses demonstrated superior predictive validity for the BCAT-SF in identifying MCI and dementia relative to the AD8. In contrast, previously reported psychometric properties or cut scores for the AD8 could not be cross-validated in this long-term care sample. Based on these findings, the BCAT-SF appears to be a more reliable and valid screening instrument than the AD8 for rapidly identifying MCI and dementia in long-term care residents.

RESUMO

In nursing homes, the ability to identify residents with cognitive impairment is critical; however, many providers fail to address symptoms of dementia due to insufficient time to assess cognition. In the current study, the authors compared two rapidly administered instruments, the Brief Interview for Mental Status (BIMS) and Brief Cognitive Assessment Tool-Short Form (BCAT-SF), in predicting specific cognitive stages. Two hundred twenty-five nursing home residents who were referred for neurocognitive evaluation and met inclusion criteria participated in the study. Both cognitive instruments were found to predict cognitive diagnoses generally, but only the BCAT-SF demonstrated sensitivity in differentiating among all cognitive levels. Receiver operating characteristic analyses did not confirm cutoff scores reported in the original BIMS study. However, sensitivity (0.91) and specificity (0.96) values for the BCAT-SF were robust for differentiating between dementia and non-dementia. The BCAT-SF appears to be a more sensitive instrument for predicting cognitive stages than the BIMS for nursing home residents.

RESUMO

OBJECTIVES: This study examines mild cognitive impairment (MCI) in long-term care settings by identifying and quantifying MCI subtypes in a combined sample of nursing home and assisted-living patients. We compared impairment thresholds of 1-SD and 1.5-SD to determine if different cut-offs differentially affect occurrence rates. METHOD: One hundred and eight participants who met general criteria for MCI were included for the purposes of this study. The general diagnosis of MCI was based on criteria. Participants were further grouped into MCI subtypes. Based on previously established norms, Brief Cognitive Assessment Tool (BCAT) factor scores were used to assess whether MCI participants met either the 1-SD and 1.5-SD impairment thresholds for memory, executive functions, and attentional capacity. RESULTS: Using both 1-SD and 1.5-SD impairment thresholds, three clear MCI subtypes were identified: amnestic, single-domain; non-amnestic, single-domain (executive); and amnestic, multi-domain (memory and executive). A fourth category (undifferentiated) was identified in patients who did not meet criteria for a distinct MCI subtype, but still had cognitive impairments. The stricter impairment threshold of 1.5-SD resulted in fewer patients classified as having any of the three domain-specific subtypes. CONCLUSION: Based on a sample of nursing home and assisted-living patients, we identified three MCI subtypes, and a fourth category consisting of participants with general MCI, but without clear evidence of domain-specific cognitive impairment. When selecting impairment thresholds, one should consider the impact on the identification of MCI subtypes and the probability of misdiagnoses.

RESUMO

BACKGROUND: Depression and anxiety are common among long-term care residents, yet both appear to be under-recognized and under-treated. In our survey of 164 geriatric health care professionals from 34 U.S. states, 96% of respondents reported that a new instrument that rapidly assesses both depression and anxiety is needed. The Brief Anxiety and Depression Scale (BADS) is a new screening tool that can identify possible major depressive episodes (MDE) and generalized anxiety disorders (GAD) in long-term care residents. METHODS: The psychometric properties of the BADS were investigated in a sample of 224 U.S. long-term care residents (aged 80.52 ± 9.07). Participants completed a battery of several individually administered mood and cognitive tests, including the BADS. MDE and GAD were diagnosed based on the DSM-IV-TR criteria. RESULTS: Adequate internal consistency and construct validity were found. A principle component analysis (PCA) revealed an Anxiety Factor and a Depression Factor, which explained 50.26% of the total variance. The Anxiety Factor had a sensitivity of 0.73 and specificity of 0.81 for identifying GAD (PPV = 0.69, NPV = 0.84). The Depression Factor had a sensitivity of 0.76 and a specificity of 0.73 for identifying MDE (PPV = 0.77, NPV = 0.72). CONCLUSIONS: The BADS appears to be a reliable and valid screening instrument for MDE and GAD in long-term residents. The BADS can be rapidly administered, is sensitive to mood diagnoses in both patients without dementia and with dementia, and produces separate depression and anxiety factor scores that can be used clinically to identify probable mood diagnoses.

RESUMO

The authors of the current article developed and investigated the psychometric properties of a Korean version of the Brief Cognitive Assessment Tool-Short Form (BCAT-SF-K) to better understand cognitive functioning of Korean American nursing home residents. In Step I, normative values were established for the BCAT-SF-K based on a sample of Korean American community-dwelling older adults (n = 34). In Step II, the authors confirmed construct validity for the BCAT-SF-K in a sample of Korean American nursing home residents (n = 26), described cognitive levels, and reported key demographics. In the nursing home sample, 84.6% of individuals had severe cognitive impairment, 7.7% had mild impairment, and 7.7% had normal cognition. The BCAT-SF-K appears to be a reliable cognitive screening measure for Korean American nursing home residents. Based on the current study's findings, Korean American nursing home residents are both older and more cognitively impaired than their American-born nursing home counterparts. Study findings are discussed in relation to improving care for these vulnerable nursing home residents.

RESUMO

ABSTRACT Background: Cognitive impairment is underrecognized and misdiagnosed among community-dwelling older adults. At present, there is no consensus about which cognitive screening tool represents the "gold standard." However, one tool that shows promise is the Brief Cognitive Assessment Tool (BCAT), which was originally validated in an assisted living sample and contains a multi-level memory component (e.g. word lists and story recall items) and complex executive functions features (e.g. judgment, set-shifting, and problem-solving). Methods: The present study cross-validated the BCAT in a sample of 75 community-dwelling older adults. Participants completed a short battery of several individually administered cognitive tests, including the BCAT and the Montreal Cognitive Assessment (MoCA). Using a very conservative MoCA cut score of <26, the base rate of cognitive impairment in this sample was 35%. Results: Adequate internal consistency and strong evidence of construct validity were found. A receiver operating characteristic (ROC) curve was calculated from sensitivity and 1-specificity values for the classification of cognitively impaired versus cognitively unimpaired. The area under the ROC curve (AUC) for the BCAT was .90, p < 0.001, 95% CI [0.83, 0.97]. A BCAT cut-score of 45 (scores below 45 suggesting cognitive impairment) resulted in the best balance between sensitivity (0.81) and specificity (0.80). Conclusions: A BCAT cut-score can be used for identifying persons to be referred to appropriate healthcare professionals for more comprehensive cognitive assessment. In addition, guidelines are provided for clinicians to interpret separate BCAT memory and executive dysfunction component scores.

RESUMO

OBJECTIVES: Verbal memory assessment metrics are an essential component of cognitive screening tools. We compared the relative utilities of word list and story recall metrics in predicting cognitive functioning in nondemented and demented nursing home patients. We selected memory metrics from the Brief Cognitive Assessment Tool (BCAT) and the Brief Interview for Mental Status (BIMS). The BCAT incorporates both word lists and story recall metrics, while the BIMS only has a word list feature. METHOD: Two hundred and thirty-nine individuals residing in a Maryland skilled nursing facility were referred for neurocognitive evaluation over a one-year period. These residents met inclusion criteria for retrospective data analysis by completing the BCAT and BIMS and were aged 60 or older. RESULTS: For the entire sample and for demented individuals, all four verbal memory metrics significantly predicted cognitive diagnosis. For nondemented individuals, only the BCAT delayed word list significantly predicted cognitive diagnosis. There appears to be enhanced utility in using both verbal memory metric types, as the inclusion of word list and story recall was a stronger predictor of cognitive diagnosis than any individual verbal memory metric. CONCLUSION: This study highlights the importance of using cognitive screening tools that contain both story recall and word list metrics. This is particularly true in long-term care settings where the base rate of cognitive impairment is high.

RESUMO

OBJECTIVES: In US nursing homes, cognitive assessment has been an essential component of the federally mandated Minimum Data Set assessment system, inclusive of the Brief Interview for Mental Status (BIMS) for identifying possible cognitive impairment. We compare it with the Brief Cognitive Assessment Tool (BCAT) to determine which instrument is more sensitive in differentiating degrees of cognitive functioning in nursing home residents. We attempt to cross-validate the psychometric properties of both measures. METHOD: Two hundred twenty-nine individuals residing in a Maryland skilled nursing facility were referred for neurocognitive evaluation over a 10-month period. One hundred eighty-nine of these residents met inclusion criteria by completing the BCAT and BIMS, and were aged 60 or older. RESULTS: The BIMS and the BCAT were confirmed to have strong internal consistency reliability and construct validity. Both cognitive tools were found to predict cognitive diagnoses generally, but only the BCAT was able to identify residents at all specific cognitive levels. The BIMS did not differentiate between residents with normal cognition and those with mild cognitive impairment, or between mild and moderate dementia. Both measures demonstrated high specificity and positive predictive values for identifying severe cognitive impairment or probable dementia. The BIMS had lower sensitivity and negative predictive values for identifying dementia compared to the BCAT. The BCAT accounted for an additional 47% of the variance in dementia diagnoses over and above BIMS scores. CONCLUSION: Based on these findings, the BCAT appears to be more sensitive than the BIMS in predicting cognitive level for nursing home residents.
