Psychometric Properties of Instruments Measuring Dyadic Communication and Environment in Dementia Care: A Systematic Review

BACKGROUND AND OBJECTIVES

A valid and reliable assessment of dementia dyadic communication and environment is essential to understand and facilitate social interaction and quality care. This review described the characteristics and evaluated psychometric properties of instruments that assess dyadic communication and environment between persons living with dementia and their caregivers.

RESEARCH DESIGN AND METHODS

A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Literature published until June 30, 2021, was searched. Ten psychometric properties and the ratio of sample size to the number of items were evaluated using the Psychometric Assessment for Self-report and Observational Tool.

RESULTS

A total of 3,708 scholarly records was identified, and 24 eligible instruments from 48 scholarly records were evaluated. Twenty-two instruments assessed dyadic communication, and 2 assessed both dyadic communication and environment. Eighteen instruments were developed to assess task-related communication and 15 for paid (professional) caregivers. All instruments were scored as low psychometric quality (score range = 0-7). Behavioral Observation Scoring System was scored the highest (total score = 7), followed by Dyadic Dementia Coding System, Grid for observation of physical and verbal behaviors of caregiver and resident, and Trouble-Indicating Behaviors and Repair (total score = 6). These instruments had low psychometric evidence for internal consistency, content validity, and structural validity.

DISCUSSION AND IMPLICATIONS

Existing instruments are in the early stages of development and validation in dementia population. Further testing is needed in diverse communication types in paid and unpaid dementia caregiver populations.

The Perceptions of People with Dementia and Key Stakeholders Regarding the Use and Impact of the Social Robot MARIO

People with dementia often experience loneliness and social isolation. This can result in increased cognitive decline which, in turn, has a negative impact on quality of life. This paper explores the use of the social robot, MARIO, with older people living with dementia as a way of addressing these issues. A descriptive qualitative study was conducted to explore the perceptions and experiences of the use and impact of MARIO. The research took place in the UK, Italy and Ireland. Semi-structured interviews were held in each location with people with dementia (n = 38), relatives/carers (n = 28), formal carers (n = 28) and managers (n = 13). The data was analyzed using qualitative content analysis. The findings revealed that despite challenges in relation to voice recognition and the practicalities of conducting research involving robots in real-life settings, most participants were positive about MARIO. Through the robot's user-led design and personalized applications, MARIO provided a point of interest, social activities, and cognitive engagement increased. However, some formal carers and managers voiced concern that robots might replace care staff.

Using Normalization Process Theory to Evaluate the Implementation of Montessori-Based Volunteer Visits Within a Canadian Long-Term Care Home

BACKGROUND AND OBJECTIVES

Montessori-based interventions (MBIs) have potential to improve the life quality of long-term care residents with dementia. In this study, we aimed to understand the processes by which staff integrated a volunteer-led MBI into practice within a special dementia care unit, and to explore staff members ' perceptions of associated strengths and limitations.

RESEARCH DESIGN AND METHODS

This study relied on a qualitative descriptive design. Following a 3-month period of volunteer involvement, we conducted 21 interviews with staff members to document perceptions of the new program and subjected interview transcripts to qualitative content analysis, guided by normalization process theory.

RESULTS

During the implementation of the volunteer-led MBI, staff members developed a shared understanding of the intervention, a sense of commitment, practical ways to support the intervention, and opinions about the value of the residents. Overall, we found that the volunteer-led MBI was quickly and successfully integrated into practice and was perceived to support both residents and staff members in meaningful ways. Nevertheless, some limitations were also identified.

DISCUSSION AND IMPLICATIONS

Volunteer-delivered MBIs are a useful adjunct to practice within a special dementia care unit. This article raises attention to some strengths and limitations associated with this approach.

Potential Pathways for Circadian Dysfunction and Sundowning-Related Behavioral Aggression in Alzheimer's Disease and Related Dementias

Patients with Alzheimer's disease (AD) and related dementias are commonly reported to exhibit aggressive behavior and other emotional behavioral disturbances, which create a tremendous caretaker burden. There has been an abundance of work highlighting the importance of circadian function on mood and emotional behavioral regulation, and recent evidence demonstrates that a specific hypothalamic pathway links the circadian system to neurons that modulate aggressive behavior, regulating the propensity for aggression across the day. Such shared circuitry may have important ramifications for clarifying the complex interactions underlying "sundowning syndrome," a poorly understood (and even controversial) clinical phenomenon in AD and dementia patients that is characterized by agitation, aggression, and delirium during the late afternoon and early evening hours. The goal of this review is to highlight the potential output and input pathways of the circadian system that may underlie circadian dysfunction and behavioral aggression associated with sundowning syndrome, and to discuss possible ways these pathways might inform specific interventions for treatment. Moreover, the apparent bidirectional relationship between chronic disruptions of circadian and sleep-wake regulation and the pathology and symptoms of AD suggest that understanding the role of these circuits in such neurobehavioral pathologies could lead to better diagnostic or even preventive measures.

A review of measures of three common dementia-related behaviors: Rejection of care, aggression, and agitation

BACKGROUND

Clustering of behavioral symptoms in dementia is common in dementia scales. However, lack of distinction may have negative treatment implications when a treatment response differs depending on classification of behaviors. Historically, rejection of care, aggression, and agitation have been lumped together. Yet, several studies have indicated these may be conceptually different behaviors.

OBJECTIVE

To examine how rejection of care, aggression, and agitation are described and operationalized in existing measures of dementia-related behaviors.

METHOD

We identified instruments developed to measure behavioral symptoms of dementia from two existing systematic reviews. Additionally, we conducted a literature review of peer-reviewed articles published from 1980 to 2017 to identify measures that were not captured in the two previous reviews.

RESULTS

43 instruments developed to measure behavioral symptoms of dementia were examined. Of these, 25 (58.1%) included items related to rejection of care; 32 (74.4%) included items related to aggression; and 35 (81.4%) included agitation items. Descriptions of these behaviors were highly variable across the instruments.

CONCLUSIONS

The review demonstrated that rejection, aggression, and agitation are measured in most scales, yet their operationalization is highly variable, and they are not typically distinguished from each other. Future efforts should be directed at developing uniform terminology to describe dementia-related behaviors while distinguishing rejection of care, aggression, and agitation in dementia scales.

The Use of Stimulus Preference Assessments for Persons with Neurocognitive Disorder: A Literature Review

Objectives: Stimulus preference assessments are a systematic, observation-based approach for identifying preferences among individuals with impaired communication skills. The purpose of this paper is to provide a review of the existing empirical literature that has utilized these methods with persons who have neurocognitive disorder (NCD).Methods: Studies were identified by searching online databases using a variety of search terms. Articles were included in the review if they were peer-reviewed, in English, were empirical in nature, and conducted a stimulus preference assessment with older adults diagnosed with NCD.Results: Eleven articles met the search criteria. Results revealed that data from stimulus preference assessments could increase activity engagement, increase requests for preferred items, identify reinforcers, and reduce behavioral and psychological symptoms.Conclusions: A small body of empirical literature suggests that data derived from stimulus preference assessments can be used to improve the lives of persons with NCD and their caregivers. Additional research is needed, however, to determine how effectively these procedures can be implemented into everyday practice in long-term care facilities.Clinical Implications: Stimulus preference assessments may provide a clinically useful means for efficiently identifying preferences in persons with severe NCD who cannot verbalize their needs.

Evaluating the feasibility and acceptability of the Namaste Care program in long-term care settings in Canada

BACKGROUND

Residents living and dying in long-term care (LTC) homes represent one of society's most frail and marginalized populations of older adults, particularly those residents with advanced dementia who are often excluded from activities that promote quality of life in their last months of life. The purpose of this study is to evaluate the feasibility, acceptability, and effects of Namaste Care: an innovative program to improve end-of-life care for people with advanced dementia.

METHODS

This study used a mixed-method survey design to evaluate the Namaste Care program in two LTC homes in Canada. Pain, quality of life, and medication costs were assessed for 31 residents before and 6 months after they participated in Namaste Care. The program consisted of two 2-h sessions per day for 5 days per week. Namaste Care staff provided high sensory care to residents in a calm, therapeutic environment in a small group setting. Feasibility was assessed in terms of recruitment rate, number of sessions attended, retention rate, and any adverse events. Acceptability was assessed using qualitative interviews with staff and family.

RESULTS

The feasibility of Namaste Care was acceptable with a participation rate of 89%. However, participants received only 72% of the sessions delivered and only 78% stayed in the program for at least 3 months due to mortality. After attending Namaste Care, participants' pain and quality of life improved and medication costs decreased. Family members and staff perceived the program to be beneficial, noting positive changes in residents. The majority of participants were very satisfied with the program, providing suggestions for ongoing engagement throughout the implementation process.

CONCLUSIONS

These study findings support the implementation of the Namaste Care program in Canadian LTC homes to improve the quality of life for residents. However, further testing is needed on a larger scale.

Preference for leisure items over edible items in individuals with dementia: A replication

We replicated previous research in which adults with dementia tended to show a preference for leisure items over edible items when presented in the same array. Additionally, we conducted engagement analyses with the highest, middle, and lowest preference leisure items to determine whether relative preference corresponded to engagement in the natural environment. The most highly preferred stimulus for 6 out of 7 participants was a leisure item, and for each of those six the top 3 preferred stimuli were leisure stimuli. For 4 participants, the most preferred stimulus also produced the longest duration of engagement. We discuss the issues we encountered when conducting preference assessments with adults with intact vocal verbal repertoires, and suggest potential explanations for the displacement of edibles by leisure stimuli in older adults with dementia.

Trust at stake: Is the "dual mission" of the U.S. Alzheimer's Association out of balance?

The official vision of the U.S. Alzheimer’s Association is “A world without Alzheimer’s disease.” The “dual mission” of the organization is “to eliminate Alzheimer’s disease through the advancement of research and to enhance care and support for individuals, their families and caregivers.” Using numerous reports from leading researchers and practitioners, a case is made by which the “dual mission” is grossly unbalanced with predominant focus on biomedical research aimed at curing the disease compared to research and practices focused on the psycho-social impacts of and adaptations to living with it. These experts discuss the likelihood of curing the disease, the complexity of realizing this goal, and the urgent need to “bring back the social and psychological aspects” of living with dementia to center stage. The moral responsibility to balancing the “dual mission” in accordance with the original motivation of the grassroots organizations who formed the association in 1980 is discussed.

Environmental Design for End-of-Life Care: An Integrative Review on Improving the Quality of Life and Managing Symptoms for Patients in Institutional Settings

CONTEXT

The environment in which end-of-life (EOL) care is delivered can support or detract from the physical, psychological, social, and spiritual needs of patients, their families, and their caretakers.

OBJECTIVES

This review aims to organize and analyze the existing evidence related to environmental design factors that improve the quality of life and total well-being of people involved in EOL care and to clarify directions for future research.

METHODS

This integrated literature review synthesized and summarized research evidence from the fields of medicine, environmental psychology, nursing, palliative care, architecture, interior design, and evidence-based design.

RESULTS

This synthesis analyzed 225 documents, including nine systematic literature reviews, 40 integrative reviews, three randomized controlled trials, 118 empirical research studies, and 55 anecdotal evidence. Of the documents, 192 were peer-reviewed, whereas 33 were not. The key environmental factors shown to affect EOL care were those that improved 1) social interaction, 2) positive distractions, 3) privacy, 4) personalization and creation of a home-like environment, and 5) the ambient environment. Possible design interventions relating to these topics are discussed. Examples include improvement of visibility and line of sight, view of nature, hidden medical equipment, and optimization of light and temperature.

CONCLUSION

Studies indicate several critical components of the physical environment that can reduce total suffering and improve quality of life for EOL patients, their families, and their caregivers. These factors should be considered when making design decisions for care facilities to improve physical, psychological, social, and spiritual needs at EOL.

Quantity of Movement as a Measure of Engagement for Dementia: The Influence of Motivational Disorders

Engagement in activities is crucial to improve quality of life in dementia. Yet, its measurement relies exclusively on behavior observation and the influence that behavioral and psychological symptoms of dementia (BPSD) have on it is overlooked. This study investigated whether quantity of movement, gauged with a wrist-worn accelerometer, could be a sound measure of engagement and whether apathy and depression negatively affected engagement. Fourteen participants with dementia took part in 6 sessions of activities: 3 of cognitive games (eg, jigsaw puzzles) and 3 of robot play (Pleo). Results highlighted significant correlations between quantity of movement and observational scales of engagement and a strong negative influence of apathy and depression on engagement. Overall, these findings suggest that quantity of movement could be used as an ancillary measure of engagement and underline the need to profile people with dementia according to their concurrent BPSD to better understand their engagement in activities.

Sundowning in Dementia: Clinical Relevance, Pathophysiological Determinants, and Therapeutic Approaches

Sundowning means the emergence or worsening of neuropsychiatric symptoms (NPS) in the late afternoon or early evening. This syndrome has been recognized since a long time in the field of dementing illnesses and is well known among most of health-care providers involved in the assistance of people with dementia. Indeed, it represents a common manifestation among persons with dementia and is associated with several adverse outcomes (such as institutionalization, faster cognitive worsening, and greater caregiver burden). Its occurrence and phenotypic characteristics may be influenced by diverse neurobiological, psychosocial, and environmental determinants. Moreover, it may pose diagnostic challenges in relation to other common causes of behavioral disruptions. Beside these considerations, this phenomenon has so far drawn limited clinical and scientific interest compared to other specific NPS occurring in dementias, as indicated by the lack of commonly agreed definitions, specific screening/assessment tools, and robust estimates on its prevalence. Accordingly, no randomized controlled trial specifically investigating the effectiveness of pharmacological and non-pharmacological strategies in managing this condition among demented patients has been yet conducted. In the present narrative review, we present and discuss available evidence concerning sundowning occurring in people with dementia. A special focus is given to its definitions, pathophysiological determinants, and clinical relevance, as well as to the clinical and therapeutic approaches required for its management in the daily practice.

Vocally disruptive behaviors in people with cognitive impaitment: Current knowledge and future research directions

This paper is a literature review of vocally disruptive behaviors (VDB) in people with dementia. This area of interest has not caught the full attention of researchers and professionals alike. Thus, the knowledge base being developed is limited. This paper will discuss the prevalence and the severity of the problem. The profiles of persons displaying VDB will be portrayed, as will the context for which VDB frequently occurs. Then, postulations regarding the etiologies for VDB and corresponding interventions will be explicated. Unfortunately, systematic studies are few and the effectiveness of different kinds of intervention strategies has not been supported by empirical data. Finally, issues pertaining to the study of VDB will be examined and directions for future research will be recommended.

Preventing Excess Disability in an Elderly Person With Alzheimer's Disease

Staff of an adult day treatment facility reported that a client diagnosed with Alzheimer's disease was exhibiting physical and verbal aggression toward other clients. Direct observation of the client's interactions at the adult day treatment facility revealed that she was neither physically nor verbally abusive but was assertive and used a cane to access social attention. Treatment consisted of three in-service trainings during which staff received information about the symptomatology of dementia, environmental factors contributing to excess disability, and the importance of environmental support for maintaining adaptive behavior in persons with dementia. Results indicate that staff perceived verbal behavior less negatively, and allowed the client to interact with others at a significantly increased frequency.

A Sequential Analysis of Verbal and Nonverbal Interaction of Two Long-Term Care Residents

This study examined interaction involving two older female residents and coresidents, care givers, and others at a Canadian long-term care institution. Twenty-four hour videotapes recorded each resident's behavior for 19 and 21 consecutive days, respectively. Interactions initiated by residents, their caregivers, and their roommates were coded from video segments occurring between 7 a.m. and 9 p.m. Lag-sequential analyses revealed that nurses initiated most of the interactions, followed by the residents themselves. Verbal contacts initiated by coresidents and other visitors to the focus residents were scant. Contact is not random but occurs in predictable sequences. The authors conclude that the nursing staff assumes the responsibility for initiating a large proportion of verbal contact and for initiating caregiving. Implications of the failure of residents to request care are discussed.

Sonas: a pilot study investigating the effectiveness of an intervention for people with moderate to severe dementia

OBJECTIVE

To investigate the feasibility and effectiveness of Sonas, a group intervention involving multisensory stimulation, reminiscence, and light physical activity.

METHODS

A total of 39 participants with moderate to severe dementia were randomized to receive either 14 sessions of Sonas or treatment as usual. Measures such as quality of life (QoL), communication, depression, anxiety, and behavioral disturbance were administered at baseline and follow-up.

RESULTS

No statistically significant results were found. However, participant attendance to sessions was good (mean = 12.4 sessions of 14 offered).

CONCLUSIONS

Sonas sessions did not lead to improvements in QoL and behavioral and psychological symptoms of dementia.

Assessing neuropsychiatric symptoms in people with dementia: a systematic review of measures

BACKGROUND

Neuropsychiatric symptoms (NPS) occur in people with dementia throughout disease course and across etiologies. NPS are associated with significant morbidities and hastened disease processes. Nevertheless, people with dementia are not systematically assessed for NPS in clinical settings. We review existing NPS measures for clinical and/or research purposes, and identify measurement gaps.

METHODS

We conducted a computerized search of peer-reviewed published studies of measures (January 1, 1980-December 1, 2013) using multiple search terms. Measures selected for review were in English, had adequate psychometric properties, and were developed for or used with people with dementia. Papers describing measures were evaluated by three coders along seven characteristics: behavioral domains, number of items, method of administration, response categories, targeted population, setting, and psychometric properties.

RESULTS

Overall, 2,233 papers were identified through search terms, and 36 papers from manual searches of references. From 2,269 papers, 85 measures were identified of which 45 (52.9%) had adequate psychometric properties and were developed or used with dementia populations. Of these, 16 (35.6%) were general measures that included a wide range of behaviors; 29 (64.4%) targeted specific behaviors (e.g. agitation). Measures differed widely as to behaviors assessed and measurement properties.

CONCLUSIONS

A robust set of diverse measures exists for assessing NPS in different settings. No measures identify risk factors for behaviors or enable an evaluation of the context in which behaviors occur. To improve clinical efforts, research is needed to evaluate concordance of behavioral ratings between formal and informal caregivers, and to develop and test measures that can identify known risks for behaviors and the circumstances under which behaviors occur.

Managing resident-to-resident elder mistreatment in nursing homes: the SEARCH approach

This article describes an educational program to inform nursing and care staff of the management of resident-to-resident elder mistreatment (R-REM) in nursing homes, using the SEARCH (Support, Evaluate, Act, Report, Care plan, and Help to avoid) approach. Although relatively little research has been conducted on this form of abuse, there is mounting interest in R-REM because such aggression has been found to be extensive and can have both physical and psychological consequences for residents and staff. The goal of the SEARCH approach is to support staff in the identification and recognition of R-REM as well as to suggest recommendations for management. The educational program and the SEARCH approach are described. Three case studies from the research project are presented, illustrating how nurses and care staff can use the SEARCH approach to manage R-REM in nursing homes. Resident and staff safety and well-being can be enhanced by the use of the evidence-based SEARCH approach.

Sundown syndrome in persons with dementia: an update

"Sundowning" in demented individuals, as distinct clinical phenomena, is still open to debate in terms of clear definition, etiology, operationalized parameters, validity of clinical construct, and interventions. In general, sundown syndrome is characterized by the emergence or increment of neuropsychiatric symptoms such as agitation, confusion, anxiety, and aggressiveness in late afternoon, in the evening, or at night. Sundowning is highly prevalent among individuals with dementia. It is thought to be associated with impaired circadian rhythmicity, environmental and social factors, and impaired cognition. Neurophysiologically, it appears to be mediated by degeneration of the suprachiasmatic nucleus of the hypothalamus and decreased production of melatonin. A variety of treatment options have been found to be helpful to ameliorate the neuropsychiatric symptoms associated with this phenomenon: bright light therapy, melatonin, acetylcholinesterase inhibitors, N-methyl-d-aspartate receptor antagonists, antipsychotics, and behavioral modifications. To decrease the morbidity from this specific condition, improve patient's well being, lessen caregiver burden, and delay institutionalization, further attention needs to be given to development of clinically operational definition of sundown syndrome and investigations on etiology, risk factors, and effective treatment options.

The comprehensive process model of engagement

BACKGROUND

Engagement refers to the act of being occupied or involved with an external stimulus. In dementia, engagement is the antithesis of apathy.

OBJECTIVE

The Comprehensive Process Model of Engagement was examined, in which environmental, personal, and stimulus characteristics impact the level of engagement.

METHODS

: Participants were 193 residents of 7 Maryland nursing with a diagnosis of dementia. Stimulus engagement was assessed via the Observational Measure of Engagement, measuring duration, attention, and attitude to the stimulus. Twenty-five stimuli were presented, which were categorized as live human social stimuli, simulated social stimuli, inanimate social stimuli, a reading stimulus, manipulative stimuli, a music stimulus, task and work-related stimuli, and two different self-identity stimuli.

RESULTS

All stimuli elicited significantly greater engagement in comparison to the control stimulus. In the multivariate model, music significantly increased engagement duration, whereas all other stimuli significantly increased duration, attention, and attitude. Significant environmental variables in the multivariate model that increased engagement were: use of the long introduction with modeling (relative to minimal introduction), any level of sound (especially moderate sound), and the presence of between 2 and 24 people in the room. Significant personal attributes included Mini-Mental State Examination scores, activities of daily living performance and clarity of speech, which were positively associated with higher engagement scores.

CONCLUSIONS

Results are consistent with the Comprehensive Process Model of Engagement. Personal attributes, environmental factors, and stimulus characteristics all contribute to the level and nature of engagement, with a secondary finding being that exposure to any stimulus elicits engagement in persons with dementia.

Reducing verbal agitation in people with dementia: evaluation of an intervention based on the satisfaction of basic needs

OBJECTIVES

Positive results have been reported with psychosocial interventions used to reduce verbal agitation (VA) in people with dementia, but there is no clear information regarding the proportion of persons who demonstrate significant behavioural improvement with such treatments. The main objectives of this pilot study are (a) to identify the proportion of persons with dementia who demonstrate significant behavioural improvement with a need-based intervention to reduce VA and (b) to further evaluate the effectiveness of this type of intervention.

METHOD

A single-group repeated measures design was used (N = 26). An individualized multicomponent intervention addressing needs for comfort, social interaction and sensory stimulation was applied by a therapist during 30 min sessions during the time of day when VA was most severe. The frequency and duration of VA were measured through computer-assisted direct observation several times before, during and after the intervention.

RESULTS

A statistically significant reduction of the duration of VA during the intervention phase relative to other phases of the protocol was found. This effect was limited to the period during which the treatment is being applied. Half of the participants (54%) demonstrated considerable behavioural improvement during the intervention (50% reduction of symptoms) and those whose functioning is best preserved showed the best response to the intervention.

CONCLUSION

This need-based intervention appears promising for improving the behaviour of a considerable proportion of patients.

The impact of stimuli on affect in persons with dementia

OBJECTIVE

To examine how presentation of different stimuli impacts affect in nursing home residents with dementia.

METHOD

Participants were 193 residents aged 60 to 101 years from 7 Maryland nursing homes who had a diagnosis of dementia (derived from the medical chart or obtained from the attending physician). Cognitive functioning was assessed via the Mini-Mental State Examination (MMSE), and data pertaining to activities of daily living were obtained through the Minimum Data Set. Affect was assessed using observations of the 5 moods from Lawton's Modified Behavior Stream. Baseline observations of affect were performed for comparisons. During the study, each participant was presented with 25 predetermined engagement stimuli in random order over a period of 3 weeks. Stimuli were categorized as live social, simulated social, manipulative, work/task-related, music, reading, or individualized to the participant's self-identity. The dates of data collection were 2005-2007.

RESULTS

Differences between stimulus categories were significant for pleasure (F(6,144) = 25.137, P < .001) and interest (F(6,144) = 18.792, P < .001) but not for negative affect. Pleasure and interest were highest for the live social category, followed by self-identity and simulated social stimuli for pleasure, and for manipulative stimuli in terms of the effect on interest. The lowest levels of pleasure and interest were observed for music. Participants with higher cognitive function had significantly higher pleasure (F(1,97) = 6.27, P < .05). Although the general trend of the impact of the different categories was similar for different levels of cognitive function, there were significant differences in pleasure in response to specific stimuli (interaction effect: F(6,92) = 2.31, P < .05). Overall, social stimuli have the highest impact on affect in persons with dementia.

CONCLUSIONS

The findings of the present study are important, as affect is a major indicator of quality of life and this study is the first to systematically examine the impact of specific types of stimuli on affect. As live social stimuli are not always readily available, particularly in busy nursing home environments, simulated social stimuli can serve as an effective substitute, and other stimuli should have a role in the activity tool kit in the nursing home. The relative ranking of stimuli was different for interest and pleasure. The findings demonstrate the differential effect of presentation of different types of stimuli on the affect of persons with dementia, and that, while the impact is greater on persons with higher levels of cognitive function, there is a different effect of varying stimuli even in persons with MMSE scores of 3 or lower. Future research should attempt to ascertain a person's degree of interest in stimuli prior to developing an intervention.

Alive and well: the state of behavioral gerontology in 2011

In this paper, the authors present a brief personal account of the senior author's 30 years of exploration in behavioral gerontology. The main thesis of the paper is that behavioral methods and interventions have found a home both in mainstream gerontology and at the National Institutes of Health (NIH). There are three sections: (a) a personal vignette discussing the problems inherent in using operant terminology in a nonoperant world; (b) a discussion, with examples from NIH sources, of the Institutes' views on behavior change; and (c) using Burgio and Burgio (1986) as a reference point, the authors show evidence of progress and vitality of behavioral gerontology in 2011.

Circadian rhythm disturbances in patients with Alzheimer's disease: a review

Circadian Rhythm Disturbances (CRDs) affect as many as a quarter of Alzheimer's disease (AD) patients during some stage of their illness. Alterations in the suprachiasmatic nucleus and melatonin secretion are the major factors linked with the cause of CRDs. As a result, the normal physiology of sleep, the biological clock, and core body temperature are affected. This paper systematically discusses some of the causative factors, typical symptoms, and treatment options for CRDs in patients with AD. This paper also emphasizes the implementation of behavioral and environmental therapies before embarking on medications to treat CRDs. Pharmacotherapeutic options are summarized to provide symptomatic benefits for the patient and relieve stress on their families and professional care providers. As of today, there are few studies relative to CRDs in AD. Large randomized trials are warranted to evaluate the effects of treatments such as bright light therapy and engaging activities in the reduction of CRDs in AD patients.

The value of social attributes of stimuli for promoting engagement in persons with dementia

The present study examined the impact of different attributes of social stimuli using the stimulus attributes aspect of the Comprehensive Process Model of Engagement ( Am J Geriatr Psychiatry. 17:299-307). Participants were 193 residents of 7 Maryland nursing homes with a diagnosis of dementia. Stimuli were chosen to represent different levels of the following social attributes: social versus not social, realistic versus not realistic, animated versus nonanimated, human versus nonhuman, and alive versus not alive. Participants had significantly longer engagement, were significantly more attentive, and displayed a significantly more positive attitude with social stimuli than with nonsocial stimuli. Longer durations and higher ratings of attention and attitude were seen with realistic and animated stimuli as compared to their counterparts. Human and live stimuli resulted in significantly more engagement than their counterparts. Giving any social stimulus to the residents is preferable to providing none, and the social attributes of stimuli should be maximized.

Can agitated behavior of nursing home residents with dementia be prevented with the use of standardized stimuli?

OBJECTIVES

To assess the relative effect of different types of stimuli on agitated behaviors of nursing home residents with dementia.

DESIGN

Repeated-measures design with randomized assignment of conditions.

SETTING

Seven Maryland nursing homes.

PARTICIPANTS

One hundred eleven nursing home residents with a diagnosis of dementia who exhibited agitation.

INTERVENTION

Different types of stimuli (music, social stimuli, simulated social stimuli, and individualized stimuli based on the person's self-identity) were presented.

MEASUREMENTS

Agitation was directly observed and recorded using the Agitation Behavior Mapping Instrument.

RESULTS

All stimulus categories were associated with significantly less physical agitation than baseline observations, and all except for manipulative stimuli were associated with significantly less total agitation. Live social stimuli were associated with less agitation than music, self-identity, work, simulated social, and manipulative stimulus categories. Task and reading stimulus categories were each associated with significantly less agitation than work, simulated social, and manipulative stimulus categories. Music and self-identity stimuli were associated with less agitation than simulated social and manipulative stimuli.

CONCLUSION

Providing stimuli offers a proactive approach to preventing agitation in persons with dementia, with live social stimuli being the most successful.

The underlying meaning of stimuli: Impact on engagement of persons with dementia

In a previous article, we discussed a theoretical framework asserting that a combination of stimulus attributes, personal attributes and environmental attributes as well as interactions among these affects engagement with stimuli by persons with dementia [Cohen-Mansfield, J., Dakheel-Ali, M., Marx, M.S., 2009. Engagement in persons with dementia: The concept and its measurement. American Journal of Geriatric Psychiatry 7, 299-307]. Based on this framework, we tested the impact on engagement of the personal meaning of stimuli, specifically examining work-like stimuli, stimuli based on the person's identity, and gender role-based activities. We hypothesized that having such meanings will render stimuli more engaging than stimuli without these meanings. Participants were 193 residents of 7 Maryland nursing homes. All participants had a diagnosis of dementia. Results confirmed the hypotheses, demonstrating that the meaning of the stimulus impacts engagement shown by persons with dementia. Interventions that involve objects or tasks with meaning specific to the person with dementia will be more likely to engage that person. Future research could explore more identity roles as well as other mechanisms affecting engagement.

Review: verbal agitation in dementia: the role of discomfort

Verbal agitation (VA) is a disturbing and commonly observed behavioral symptom in people with dementia. Although several different variables contribute to VA, it seems that discomfort plays an important role. The overall objective of this article is to review the relationship between VA and discomfort among people with dementia. Specifically, this article discusses the place of discomfort within the conceptualizations of VA, empirical support for the association between discomfort and VA, and practical implications of this relationship in the assessment and treatment of VA. This article contributes to a better understanding of VA and provides recommendations for prevention and effective intervention.

Engaging nursing home residents with dementia in activities: the effects of modeling, presentation order, time of day, and setting characteristics

We examined the impact of setting characteristics and presentation effects on engagement with stimuli in a group of 193 nursing home residents with dementia (recruited from a total of seven nursing homes). Engagement was assessed through systematic observations using the Observational Measurement of Engagement (OME), and data pertaining to setting characteristics (background noise, light, and number of persons in proximity) were recorded via the environmental portion of the Agitation Behavior Mapping Inventory (ABMI; Cohen-Mansfield, Werner, & Marx, (1989). An observational study of agitation in agitated nursing home residents. International Psychogeriatrics, 1, 153-165). Results revealed that study participants were engaged more often with moderate levels of sound and in the presence of a small group of people (from four to nine people). As to the presentation effects, multiple presentations of the same stimulus were found to be appropriate for the severely impaired as well as the moderately cognitively impaired. Moreover, modeling of the appropriate behavior significantly increased engagement, with the severely cognitively impaired residents receiving the greatest benefit from modeling. These findings have direct implications for the way in which caregivers could structure the environment in the nursing home and how they could present stimuli to residents in order to optimize engagement in persons with dementia.

Étude préliminaire d'une intervention non-pharmacologique pour réduire l'agitation verbale chez les personnes atteintes de démence

Verbally agitated behaviours are among the behavioural symptoms of dementia most commonly encountered in long-term care facilities. These behaviours may be related to unmet needs that cannot be expressed adequately because of cognitive impairment. The objective of this preliminary study is to assess an intervention, based on the needs of social attention, sensory stimulation, and comfort, for managing verbally agitated behaviours in long-term care demented patients. A multiple baseline case study design was used, with two participants.

The impact of past and present preferences on stimulus engagement in nursing home residents with dementia

OBJECTIVES

We examined engagement with stimuli in 193 nursing home residents with dementia. We hypothesized that activities and stimuli based on a person's past and current preferences would result in more engagement than other activities/stimuli.

METHOD

The expanded version of the self-identity questionnaire [Cohen-Mansfield, J., Golander, H. & Arheim, G. (2000)] was used to determine participants' past/present interests (as reported by relatives) in the following areas: art, music, babies, pets, reading, television, and office work. We utilized the observational measurement of engagement (Cohen-Mansfield, J., Dakheel-Ali, M., & Marx, M.S. (2009).

RESULTS

Analysis revealed that residents with current interests in music, art, and pets were more engaged by stimuli that reflect these interests than residents without these interests.

CONCLUSION

Our findings demonstrate the utility of determining a person's preferences for stimuli in order to predict responsiveness. Lack of prediction for some stimuli may reflect differences between past preferences and activities that are feasible in the present.

Sundowning: Disruptive Behavior With Many Causes

Most long-term care clinicians are familiar with sundowning syndrome, a period at the end of the day when residents with dementia may exhibit more agitation or behavioral disturbances. Little research has been done in this area, but that which has been completed implicates frustrated communication, sleep disturbances related to dementia, and poor light exposure as possible causes. Sundowning may be the manifestation of residents' distant memories of heightened activity in the evening and the inability to adapt to a different and less active long-term care environment.

The impact of personal characteristics on engagement in nursing home residents with dementia

OBJECTIVE

To examine the impact of personal attributes on engagement in persons with dementia.

METHODS

Participants were 193 residents of seven Maryland nursing homes. All participants had a diagnosis of dementia. Cognitive functioning was assessed via the Mini-Mental State Examination, and engagement was assessed via the Observational Measure of Engagement. Data pertaining to activities of daily living were obtained from the Minimum Data Set.

RESULTS

Women had longer mean engagement duration than men, and significant results were not seen with the other demographic variables. Significant, positive correlations were found between higher cognitive functioning and longer engagement duration, more attention, a more positive attitude, and a higher refusal rate. There was a positive and significant correlation between the comorbidity index and engagement duration, and between the number of medications and attention. All functional status variables yielded significance in a positive direction. Participants with poor hearing had a higher refusal rate. Cognitive status was the most consistent and potent predictor of engagement in this population.

CONCLUSION

Despite a higher refusal rate among those with higher cognitive levels, their overall engagement with stimuli is higher. Caregivers should anticipate higher refusal rates in those with poor hearing, and therefore compensatory methods should be used in presenting stimuli in this population. The potent role of cognitive and functional status on engagement of persons with dementia underscores the importance of tailoring activities to nursing home residents' needs, interests, and limitations.

Engagement in persons with dementia: the concept and its measurement

PURPOSE

The aim of this article is to delineate the underlying premises of the concept of engagement in persons with dementia and present a new theoretical framework of engagement.

SETTING/SUBJECTS

The sample included 193 residents of seven Maryland nursing homes. All participants had a diagnosis of dementia.

METHODOLOGY

The authors describe a model of factors that affect engagement of persons with dementia. Moreover, the authors present the psychometric qualities of an assessment designed to capture the dimensions of engagement (Observational Measurement of Engagement). Finally, the authors detail plans for future research and data analyses that are currently underway.

DISCUSSION

This article lays the foundation for a new theoretical framework concerning the mechanisms of interactions between persons with cognitive impairment and environmental stimuli. Additionally, the study examines what factors are associated with interest and negative and positive feelings in engagement.

The impact of different dog-related stimuli on engagement of persons with dementia

OBJECTIVE

To provide further empirical evaluation of the effectiveness of animal-assisted therapy in nursing home residents with dementia.

METHODS

Participants were 56 residents of 2 suburban Maryland nursing homes and had a diagnosis. Activities of daily living performance was assessed via the minimum data set and cognitive functioning assessed using the Mini-Mental State Examination. Engagement with dog-related stimuli was systematically assessed via the observational measurement of engagement.

RESULTS

Mean engagement duration was significantly lower for the small dog. Highest mean engagement duration was found for the puppy video, followed by the real dog and lowest was for the dog-coloring activity. Positive attitudes were found toward the real dogs, robotic dog, the puppy video, and the plush dog. No significant differences were found in engagement duration among our dog-related stimuli.

CONCLUSIONS

Nursing homes should consider animal-assisted therapy and dog-related stimuli, as they successfully engage residents with dementia.

Vocally disruptive behavior in the elderly: a systematic review

BACKGROUND

Vocally disruptive behavior (VDB) in the elderly is a common condition, especially in people with dementia, but difficult to treat. It may occur in as many as 40% of nursing home residents. This study is a review of the existing literature on this condition.

METHOD

The literature review was conducted using PubMed (particularly Medline and the Cochrane database) and reference lists from relevant publications in English, French, and German.

RESULTS

Most studies are small and no conclusive prevalence data are available. Many biological and psychosocial treatments have been advocated, but most studies are little more than anecdotal case reports. It is evident that VDB can have deleterious consequences on others and the patients themselves, although no studies specifically examine the range or the pervasiveness of VDB. Etiopathogenic research on VDB is still in its infancy.

CONCLUSIONS

Most aspects surrounding VDB are insufficiently understood. The heterogeneity and multiple contributive factors regarding VDB suggest quite convincingly that a panoply of different interventions tailored to the individual's needs will be required to overcome VDB and the suffering related to it.

The impact of stimulus attributes on engagement of nursing home residents with dementia

We examined the influence of stimulus attributes on the engagement of 69 nursing home residents with dementia. Specifically, we looked at work-related stimuli versus manipulative block stimuli, and whether the color, size, and material of a stimulus affect the duration and quality of engagement. Engagement was assessed using the Observational Measurement of Engagement (OME). Results revealed a clear preference for the work-related rather than manipulative block stimuli. In addition, the study participants showed a significant preference for small rather than large blocks, regardless of color or material. The effect of material and color was not statistically significant. These findings may assist nursing home caregivers who wish to provide appropriate stimuli for engaging nursing home residents with dementia.

Comparison of Caregiver and Occupational Therapist Ratings of Dementia Patients' Performance of Activities of Daily Living

Although proxy reports of activities of daily living (ADLs) are commonly used, especially when the care recipient has dementia, how well these caregiver reports correspond to professionals' ratings is not always clear. In this study, dementia caregivers completed an orally administered version of the Self-Care subscale of the Functional Independence Measure (FIM). ADL interactions were videotaped in the home, and independent raters assigned a FIM score to these interactions. An occupational therapist later viewed the videotaped ADLs and assigned FIM scores to those interactions. These three sets of scores were then compared. All possible correlations were significant (n = 21; p ≤ .005; r s = .620 to .933; Mdn = .862), and there were no significant differences among ratings obtained from the different sources. These results support earlier conclusions regarding the validity and clinical utility of caregiver proxy ratings of functional ability in elders with dementia.

The management of inappropriate vocalisation in dementia: a hierarchical approach

BACKGROUND

Patients with dementia can demonstrate noisy behaviours such as screaming, repetitive speech, moaning and singing. Such behaviours can be grouped under the title of "Inappropriate Vocalisation" which is used in this article to describe any noise making which impacts detrimentally upon patients, families or those in a caring role. Inappropriate vocalisation is notoriously difficult to treat and clinicians may have to rely on a "trial and error" approach when attempting to limit the distress it causes.

OBJECTIVES

This paper applies a hierarchical approach to Behavioural and Psychological Symptoms of Dementia (BPSD) in attempting to tackle inappropriate vocalisation systematically. Nine steps are ranked within three stages, with evidence for each intervention being considered sequentially in terms of the likelihood for success as the authors attempt to review the relevant literature.

METHODS

The authors performed a search of the medline database using the key words "screaming," "shouting," "persistent vocalisation" and "inappropriate vocalisation" combined with the key word "dementia". Further searches of the references of medline generated articles revealed a second group of articles of use in this review.

RESULTS

The search generated 53 reviews, research papers, case studies or letters, 36 of which are referenced in this article and the remaining references drawn from reading by the authors around the subject and related problems.

CONCLUSION

Interventions for inappropriate vocalisation in dementia are not limited to medication. Environmental factors and behavioural approaches are considered ahead of pharmacotherapy as the concepts of Underlying Illness, Hidden Meaning and Empirical Treatments are used to structure consideration of important, and sometimes overlooked, issues including pain, depression and overall level of stimulation.

Behavioral characteristics of agitated nursing home residents with dementia at the end of life

PURPOSE

The purpose of this study was to examine group differences in verbal agitation, verbal interaction, bed restraint, pain, analgesic and neuroleptic medication use, and medical comorbidity among agitated nursing home residents who died during a 6-month clinical trial compared with residents of the same gender and similar initial cognitive status who did not die during the trial.

DESIGN AND METHODS

We conducted a two-group secondary data analysis of prospective observational data from 10 nursing homes in Birmingham, Alabama. By means of chart review, resident assessments, surveys of certified nursing assistants, and direct observation of residents' daily behaviors and environment, 32 residents (87.34 +/- 7.29 years) with a Mini-Mental State Examination (MMSE) score = 4.31 (+/-5.54) who died were compared with 32 residents (84 +/- 6.96 years) with a mean MMSE score = 4.28 (+/-5.49) who did not die during the clinical trial.

RESULTS

Residents who died displayed more verbal agitation, less time in verbal interaction with staff, and almost twice as much time restrained in bed during observation time in comparison with residents who did not die during the clinical trial. However, groups did not differ significantly in severity of comorbid illness, functional status, number of painful diagnoses, certified nursing assistants' reports of residents' pain, or opioid or nonopioid analgesic prescription or dosage. Surviving residents were more likely to receive neuroleptic medication than residents who died.

IMPLICATIONS

Results suggest that agitated nursing home residents may exhibit a heightened level of verbal agitation, decreased verbal interaction with staff, and increased bed restraint up to 3 months prior to death. Prospective observational studies are needed to identify markers for imminent mortality among nursing home residents.

Verbal and physical non-aggressive agitated behaviors in elderly persons with dementia: robustness of syndromes

OBJECTIVE

More than a decade ago, different syndromes of agitation were identified in elderly nursing home residents, and it was found that these syndromes correlate with medical, cognitive, and psychosocial functioning. The present study was conducted to examine the robustness of two major syndromes, verbal agitation and physical non-aggressive agitation, as assessed via direct observations.

METHODS

Study participants were 175 elderly persons with dementia recruited from 11 nursing home facilities in Maryland. Observations of the participants' behavior were conducted using the agitated behaviors mapping instrument.

RESULTS

The profiles that emerged for physically agitated residents and for verbally agitated residents were remarkably similar to those originally reported. Specifically, verbally agitated behaviors correlated with female gender, with cognitive decline, poor performance of activities of daily living, impaired social functioning, and signs of depressed affect. Physically non-aggressive agitated behaviors correlated with cognitive impairment and with fewer concurrent medical diagnoses.

CONCLUSIONS

Examining correlates of different syndromes of agitated behaviors may provide researchers with valuable information that can be used for in-depth analysis of both the characterization and etiology of agitation, thus paving the way for the development of interventions that target particular types of problem behaviors.
