Correlates of disruptive behavior in cognitively impaired elderly nursing home residents

The Prevalence of Psychotic Symptoms, Violent Ideation, and Disruptive Behavior in a Population With SARS-CoV-2 Infection: Preliminary Study

Background

The COVID-19 disease results from infection by the SARS-CoV-2 virus to produce a range of mild to severe physical, neurological, and mental health symptoms. The COVID-19 pandemic has indirectly caused significant emotional distress, triggering the emergence of mental health symptoms in individuals who were not previously affected or exacerbating symptoms in those with existing mental health conditions. Emotional distress and certain mental health conditions can lead to violent ideation and disruptive behavior, including aggression, threatening acts, deliberate harm toward other people or animals, and inattention to or noncompliance with education or workplace rules. Of the many mental health conditions that can be associated with violent ideation and disruptive behavior, psychosis can evidence greater vulnerability to unpredictable changes and being at a greater risk for them. Individuals with psychosis can also be more susceptible to contracting COVID-19 disease.

Objective

This study aimed to investigate whether violent ideation, disruptive behavior, or psychotic symptoms were more prevalent in a population with COVID-19 and did not precede the pandemic.

Methods

In this preliminary study, we analyzed questionnaire responses from a population sample (N=366), received between the end of February 2021 and the start of March 2021 (1 year into the COVID-19 pandemic), regarding COVID-19 illness, violent ideation, disruptive behavior, and psychotic symptoms. Using the Wilcoxon rank sum test followed by multiple comparisons correction, we compared the self-reported frequency of these variables for 3 time windows related to the past 1 month, past 1 month to 1 year, and >1 year ago among the distributions of people who answered whether they tested positive or were diagnosed with COVID-19 by a clinician. We also used multivariable logistic regression with iterative resampling to investigate the relationship between these variables occurring >1 year ago (ie, before the pandemic) and the likelihood of contracting COVID-19.

Results

We observed a significantly higher frequency of self-reported violent ideation, disruptive behavior, and psychotic symptoms, for all 3 time windows of people who tested positive or were diagnosed with COVID-19 by a clinician. Using multivariable logistic regression, we observed 72% to 94% model accuracy for an increased incidence of COVID-19 in participants who reported violent ideation, disruptive behavior, or psychotic symptoms >1 year ago.

Conclusions

This preliminary study found that people who reported a test or clinician diagnosis of COVID-19 also reported higher frequencies of violent ideation, disruptive behavior, or psychotic symptoms across multiple time windows, indicating that they were not likely to be the result of COVID-19. In parallel, participants who reported these behaviors >1 year ago (ie, before the pandemic) were more likely to be diagnosed with COVID-19, suggesting that violent ideation, disruptive behavior, in addition to psychotic symptoms, were associated with COVID-19 with an approximately 70% to 90% likelihood.

Aggressive behavior in institutionalized elders: A theoretical framework

This review article explores current research on aggression in institutionc ized elders and proposes a theoretical framework for use by caregivers. The relationships of brain dysfunction, past behaviors, social networks and environmental triggers to the expression of aggression a te discussed. The framework can be used to generate research hypothesis, or as a guide for assessing rise factors associated with these behaviors.

Passive behaviors in Alzheimer' disease: A descriptive analysis

Fifteen empirical studies investigating passive behaviors (PB) in Alzheimer's disease (AD) were examined. Results indicated that PB are distinct from depression; they tend to increase over the course of the disease; and they can be related to cognitive status and personality changes. Absence of theoretical frameworks, lack of an instrument specifically designed to measure PB in AD, and no clearly established operational concept capable of describing and unifying behaviors into a syndrome of passivity represent problem areas for researchers. Future research to determine whether PB are a “default” mechanism brought on by AD itself or the result of a need to isolate or withdraw in order to cope with multiple stressors is indicated. Antecedent behaviors, those associated with passivity itself as well as caregiver responses and interventions also warrant investigation.

Resident-to-Resident Abuse: A Scoping Review

L'abus de résidents par d'autres résidents parmi de foyers de soins de longue durée (SLD) implique l'agressivité et la violence et peut avoir des conséquences graves pour tous les deux, agresseurs et victimes. Jusqu'à présent, il n'y a eu aucune tentative d'évaluer systématiquement la portée de ce problème au Canada. Pour combler cette lacune, nous avons entrepris une étude de délimitation de l'étendue pour améliorer la compréhension de l'abus chez les résidents des foyers de SLD. Nous présentons aussi un ensemble redigé de données canadiennes sur l'abus chez les résidents. On a cherché neuf bases de données bibliographiques électroniques; un total de 784 résumés a été trouvés, mais seulement 32 ont satisfait les critères d'inclusion. La majorité des documents (75 pour cent) étaient des études de cas rétro-perspectives, des études qualitatives et critiques/commentaires. Parmi eux, seuls 14 se consacrent exclusivement à l'abus parmi les résidents. L'ensemble redigé de données canadiennes suggère que l'abus des résidents par d'autres résidents représente environ un tiers des cas d'abus signalés. Afin de faire connaître cette phénomène et d'aider à diminuer son incidence, des recommandations pour la recherche future, la pratique clinique et la politique sont fournis.

Effect of the bathing without a battle training intervention on bathing-associated physical and verbal outcomes in nursing home residents with dementia: a randomized crossover diffusion study

OBJECTIVES

To evaluate the effectiveness of the Bathing Without a Battle intervention in reducing physical and verbal aggressive behaviors for nursing home residents with dementia.

DESIGN

A randomized crossover diffusion study, with one group receiving the intervention after one round of baseline observations and a delayed intervention group receiving the intervention after two rounds of baseline observations.

SETTING

Six nursing home facilities in the state of New York.

PARTICIPANTS

Nursing home residents with dementia (N = 240).

INTERVENTION

The Bathing Without a Battle educational program, designed for direct-care staff members responsible for bathing residents diagnosed with dementia and implemented through a train-the-trainer model.

MEASUREMENTS

Rates of verbal and physical aggressive and agitated behaviors were measured using the Care Recipient Behavior Assessment; secondary measures of effect included bath duration, bath modality, and antipsychotic medication use.

RESULTS

In spite of implementation obstacles (consent delays and change in leadership at one facility), a significant change was observed in how residents were bathed that translated into a significant reduction in the rate of aggressive and agitated behaviors, particularly verbal, during residents' baths. The use of in-bed baths increased 17%, and average bath duration decreased significantly (average 1.5 minutes less) in the postintervention period, particularly for in-bed baths. Verbal behaviors declined 17.8% (P = .008), combined verbal and physical behaviors declined 18.6% (P = .004), and antipsychotic use declined 30% (P = .002) after the intervention.

CONCLUSION

The Bathing Without a Battle educational program, delivered through a train-the-trainer format, is an effective means of improving the bathing experience of residents with dementia in nursing homes. This research supports broadly adopting this intervention, especially for nursing homes serving many residents with dementia.

Validité et fidélité de l'Inventaire d'agitation de Cohen-Mansfield

Agitation in older persons is a major problem for the agitated individual and those around him/her. French-language measures of agitation with demonstrated validity and reliability are necessary for research and interventions in the French-speaking community. The goal of this study is to verify the reliability and validity of the “Inventaire d'agitation de Cohen-Mansfield” (IACM), a French version of the Cohen-Mansfield Agitation Inventory. The IACM measures the frequency of 29 agitated behaviours during a two-week period. Ninety-nine residents of a long-term care facility participated in this study. Results demonstrate the inter-rater reliability (r = .72), test-retest reliability (r = .72), internal consistency (Cronbach's alpha from .75 to .77), concurrent validity (r = .74) and construct validity (all r are significant, p < .05) of the IACM.

Factors associated with aggressive behavior among nursing home residents with dementia

PURPOSE

In an attempt to more thoroughly describe aggressive behavior in nursing home residents with dementia, we examined background and proximal factors as guided by the Need-Driven Dementia-Compromised Behavior model.

DESIGN AND METHODS

We used a multivariate cross-sectional survey with repeated measures; participants resided in nine randomly selected nursing homes within four midwestern counties. The Minimum Data Set (with verification by caregivers) identified participants. We used a disproportionate probability sample of 107 participants (51% with a history of aggressive behavior) to ensure variability. Videotaped care events included four of direct care (shower baths, meals, dressing, and undressing) and two of nondirect care (two randomly selected 20-minute time periods in the afternoon and evening). The majority of participants (75%) received three shower baths, for a total of 282 videotaped baths.

RESULTS

Because the shower bath was the only care event significantly related to aggressive behavior (F = 6.9, p < .001), only those data are presented. Multilevel statistical modeling identified background factors (gender, mental status score, and lifelong history of less agreeableness) and a proximal factor (amount of nighttime sleep) as significant predictors (p < .05) of aggressive behavior during the shower bath. We found significant correlations between aggressive behavior and negative subject affect (r = .27) during the bath, and aggressive behavior and lifetime agreeableness level (r = -.192). We also found significant correlations between mental status and the amount of education (r = .212), and between negative caregiver affect and negative participant affect (r = .321).

IMPLICATIONS

We identified three background and one proximal factor as significant risk factors for aggressive behavior in dementia. Data identify not only those persons most at risk for aggressive behavior during care, but also the care event most associated with aggressive behavior. Together these data inform both caregiving for persons with dementia as well as the design of intervention studies for aggressive behavior in dementia.

Executive control functioning and functional ability in older adults

The manner in which executive control functioning exerts its influence on functional tasks was investigated. Sixty older adults were administered neuropsychological tasks tapping into four domains of executive control function, including working memory, planning, fluency, and flexibility. A test of performance-based functional ability also was administered. Correlational analyses demonstrated that working memory was most strongly associated with performance-based functional ability; however, impairment in planning appeared to best predict performance-based functional decrement in simultaneous regression models. Results highlight the role of planning in the maintenance of functional ability, as measured by performance-based functional measures.

Correlates of physical health of informal caregivers: a meta-analysis

Effects of caregiving on physical health have received less theoretical and empirical attention than effects on psychological health. This meta-analysis integrates results from 176 studies on correlates of caregiver physical health. Caregiver depressive symptoms had stronger associations with physical health than did objective stressors. Higher levels of care recipient behavior problems were more consistently related to poor caregiver health than were care receiver impairment and intensity of caregiving. Higher age, lower socioeconomic status, and lower levels of informal support were related to poorer health. Predictors of physical health are not identical to predictors of psychological health. Associations of caregiving stressors with health were stronger among older samples, dementia caregivers, and men. In sum, negative effects of caregiving on physical health are most likely to be found in psychologically distressed caregivers facing dementia-related stressors.

A TRAINING PROGRAM FOR Managing Agitation of Residents in Long-Term Care Facilities: DESCRIPTION AND PRELIMINARY FINDINGS

The purpose of this article is to describe a training program for managing agitation of long-term care residents and to report results of a pilot study. The program emphasizes the development of behavioral skills for the assessment, prevention, and reduction of both aggressive and non-aggressive agitated behavior. It includes 8 hours of class instruction followed by 8 hours of weekly supervision by the trainers. The nursing staff of all working shifts of a unit located in a large nursing home and the residents of this unit participated in the pilot study. Residents and staff were assessed prior to and after the 2-month training program. Staff members reported using behavioral techniques to a greater extent and feeling more effective in managing agitation after training. More than 90% of staff members were satisfied with the training program. During the supervision period, the staff developed and implemented individualized interventions for two residents. The interventions involved providing more attention to these residents and, in one case, modifying some aspects of the direct environment which seemed to trigger agitation. Both residents were less agitated after the interventions were implemented. Moreover, there was a reduction in the number and frequency of agitated behaviors for the other residents of the trainees' unit following staff training.

Disruptive Behaviors in Veterans Affairs Nursing Home Residents: How Different Are Residents with Serious Mental Illness?

OBJECTIVES

To determine the prevalence and correlates of behavior problems of residents of Veterans Affairs (VA) nursing homes and to compare residents with serious mental illness (SMI) with other resident groups.

DESIGN

This study combined cross-sectional resident assessments with administrative data for all residents in VA nursing homes. Multivariate ordinal logistic regression was used to evaluate associations between resident characteristics and problem behaviors.

SETTING

Nursing home care units in the VA healthcare system.

PARTICIPANTS

A total of 9,618 nursing home residents assessed as part of the VA's April 2001 national resident census.

MEASUREMENTS

The Patient Assessment Instrument assessed each resident's verbally disruptive, physically aggressive, and socially inappropriate behaviors in the prior 4 weeks. Functional limitations in eating, mobility, toileting, and transfer were assessed. Diagnoses were evaluated for the stay and up to 6 months before assessment.

RESULTS

Almost one-fifth (17.9%) of residents received a diagnosis of SMI. Residents with SMI or dementia had greater behavior problems than residents with neither condition. Residents with SMI (and without dementia) exhibited more verbal disruption than residents with dementia (and without SMI), but the two subgroups did not differ in physically aggressive or socially inappropriate behavior.

CONCLUSION

Many VA nursing home residents have SMI. Their level of behavior problems is comparable with that of residents with dementia. Clinical practice and nursing home staff training must encompass geriatric mental health and behavior management to meet the needs of residents with SMI.

Effect of Person-Centered Showering and the Towel Bath on Bathing-Associated Aggression, Agitation, and Discomfort in Nursing Home Residents with Dementia: A Randomized, Controlled Trial

OBJECTIVES

To evaluate the efficacy of two nonpharmacological techniques in reducing agitation, aggression, and discomfort in nursing home residents with dementia. The techniques evaluated were person-centered showering and the towel bath (a person-centered, in-bed bag-bath with no-rinse soap).

DESIGN

A randomized, controlled trial, with a usual-care control group and two experimental groups, with crossover.

SETTING

Nine skilled nursing facilities in Oregon and six in North Carolina.

PARTICIPANTS

Seventy-three residents with agitation during bathing (69 completed the trial) and 37 nursing assistants who bathed them.

MEASUREMENTS

Agitation and aggression were measured using the Care Recipient Behavior Assessment; discomfort was measured using a modification of the Discomfort Scale for Dementia of the Alzheimer Type. Raters who were blinded to subject status coded both from videotaped baths. Secondary measures of effect included bath duration, bath completeness, skin condition, and skin microbial flora.

RESULTS

All measures of agitation and aggression declined significantly in both treatment groups but not in the control group, with aggressive incidents declining 53% in the person-centered shower group (P<.001) and 60% in the towel-bath group (P<.001). Discomfort scores also declined significantly in both intervention groups (P<.001) but not in the control group. The two interventions did not differ in agitation/aggression reduction, but discomfort was less with the towel bath (P=.003). Average bath duration increased significantly (by a mean of 3.3 minutes) with person-centered showering but not with the towel bath. Neither intervention resulted in fewer body parts being bathed; both improved skin condition; and neither increased colonization with potentially pathogenic bacteria, corynebacteria, or Candida albicans.

CONCLUSION

Person-centered showering and the towel bath constitute safe, effective methods of reducing agitation, aggression, and discomfort during bathing of persons with dementia.

Teaching staff to respond effectively to cognitively impaired residents who display self-protective behaviors

A randomized controlled trial (RCT) was implemented to evaluate the effectiveness of a 7 1/2 hour educational program designed to provide staff with the knowledge, skill, and confidence to manage physical self-protective behaviors of cognitively impaired long-term care residents. This RCT using a pretest/post-test design was conducted using consenting staff members (n = 40) who were randomly allocated to either a control or experimental group. The main outcome measure was a skills lab that evaluated participants 'responses to simulated patients. Both groups participated in the skills lab prior to training, and six weeks after the experimental group completed the program. Pre- and post-training and skills lab observational field notes were subjected to thematic content analysis. Twenty-eight staff members completed both pre- and post-training assessment measurements. Descriptive statistics and paired t-test analyses yielded statistically significant differences in change scores for performance indicators in three simulation scenarios. Analysis of the qualitative data support the finding that, once trained, staff felt better prepared to manage self-protective behaviors. The results suggest that an initiative to educate staff will enhance knowledge, improve performance, and provide the confidence necessary for staff to respond positively to overt physical behaviors in cognitively impaired elders.

Correlates of behavioral disturbances and pattern of psychotropic medication use in five skilled nursing facilities

There are several treatment options for behavioral disturbances (BDs) in dementia. However, the choice of a specific psychotropic agent is directed by personal preferences and local community practice patterns. We examined the relationship between common clusters of BDs and the use of different classes of psychotropic agents in our community. A cross-sectional study of 430 long-term care residents from 5 nursing homes was undertaken. The Behavior Measurement Scale (BMS) was used to measure the frequency of BDs grouped in 4 categories. Residents with > 4 BD episodes in at least one category during a 2-week observation period were the behavior group and were considered to have clinically significant BDs. A sample of patients who had < 4 BDs in all BMS categories during the same observation period defined the nonbehavior group. A BD cluster was defined as > 4 BDs occurring in one or more BMS categories during the 2-week observation. Data on functional status, comorbidity, use of benzodiazepines, antidepressants, and neuroleptic agents were collected with chart review. The chi-square test was used to examine the correlation between variables. Clinically significant BDs were identified in 27.2% (117/430) of the residents in the sample. Five of 15 behavior clusters accounted for 73% of all clinically significant BDs. The 5 clusters were verbally nonaggressive behaviors (cluster 1, 20.5%), behaviors from all 4 categories (cluster 2, 17.9%), verbally and physically nonaggressive behaviors (cluster 3, 14.5%), physically nonaggressive behaviors (cluster 4, 12.8%), and verbally aggressive and nonaggressive behaviors (cluster 5, 7.7%). Cluster 5 had a negative correlation with functional impairment (P = .009). There was a significant correlation between cluster 2 and benzodiazepine use (P = .014). No other significant correlation was found between any of the 5 clusters and demographic variables, comorbidity status, and use of antidepressant or neuroleptic medications. Residents in the behavior group had higher impairment in self-feeding (P = .036) and bathing (P < .001) and were more likely to be treated with benzodiazepines (P = .004) and neuroleptic agents (P = .009) than residents in the nonbehavior group (n = 116). The higher use of neuroleptics and benzodiazepines in the behavior group compared with the nonbehavior group indicates that BDs are being identified for treatment, but the medications used may not be efficacious. The lack of association between specific classes of psychotropic medications and distinct behavior clusters indicates that clinicians are not using a standardized approach to target the neurochemical abnormalities that may underlie certain behavior clusters. Some behavior clusters correlate with impairment in specific activities of daily living categories such as bathing and feeding, making room for nonpharmacologic interventions.

Predictors of agitation in nursing home residents

Agitation in nursing home residents presents a serious challenge to caregivers and may place residents at risk for harm. Understanding the etiology of agitation can assist clinicians in developing nonpharmacologic interventions for preventing and treating this problem. The purpose of this study was to examine independent and common predictors of resident agitation with structural equation modeling. Agitation was measured with both a standardized staff report rating scale and direct behavioral observation. No indirect or mediating effects were found. Cognitive impairment, vision and hearing impairment, and gender were found to be independent predictors of agitation as measured by direct behavioral observation. Only cognitive impairment was found to be predictive of agitation as measured by the standardized staff report scale. An unexpected finding was that vision impairment appeared to exert a protective effect for agitation in these severely cognitively impaired residents. The clinical implications of these findings are discussed as well as the relative merits of the two methods of measuring agitation.

Timed-event sequential analysis of agitation in nursing home residents during personal care interactions with nursing assistants

Computer-assisted behavioral observation data were collected from 66 nursing home residents while they received assistance during personal care routines from a certified nursing assistant (CNA). Data were collected both before and after a comprehensive behavior-management and communication-skills training program was delivered to the nursing staff. A total of 30 residents showed 6 or more episodes of disruptive vocalization or other forms of agitation during baseline observations, and timed-event sequential analysis methods were used to test whether certain CNA behaviors either elicited or prevented onsets of agitation in these 30 residents. Simple verbal prompts used by CNAs during personal care routines before staff training were found to elicit agitation onset ( p =.03), whereas positive statements to the resident were found to reduce the likelihood of agitation onset (p =.02). In a previous analysis of the effects of staff training, we found that rates of resident agitation were significantly lower after training compared with baseline and that CNAs increased their rates of positive statements to residents. In the present study, timed-event sequential analyses indicated that the verbal prompts used by CNAs during personal care routines were no longer associated with an increased rate of resident agitation after staff training among the 20 residents who showed 6 or more episodes of agitation both before and after staff training. These findings suggest that the staff training program improved the quality of CNA verbal prompts. The sequential analysis of observational data provides an important method for studying interpersonal interactions, including those of nursing home residents and the nursing staff who care for them.

Teaching and maintaining behavior management skills in the nursing home

PURPOSE

To examine the efficacy of a comprehensive behavior management skills training program for improving certified nursing assistants' (CNA) skill performance in the nursing home, to assess the effectiveness of a staff motivational system for maintaining newly acquired behavior management skills for a 6-month period, and to evaluate any resulting effects on resident agitation.

DESIGN AND METHODS

This study used a randomized clinical trial of 88 residents with behavior disturbances and 106 CNAs who cared for them in two urban nursing homes. After CNAs received 4 weeks of behavior management training, supervisory nursing staff implemented formal staff management (FSM), designed to maintain training effects over time. The supervisory staff used conventional staff management (CSM, usual supervisory routine) on control units. We completed behavioral observations and paper-and-pen assessments at baseline and repeated them during a 4-week post-intervention phase and at 3- and 6-month follow-ups.

RESULTS

During the immediate post-training phase, both the FSM and CSM groups improved five out of seven communication skills and the ability to delay physical assistance during care routines. Although CNAs showed a reduction in the use of ineffective behavior management strategies, they did not increase their use of effective behavioral strategies. Follow-up assessments suggested that the FSM system was more effective than CSM for maintaining and even improving communication skills over time. Resident agitation was reduced during care interactions and maintained at follow-up.

IMPLICATIONS

The behavior management skills training program improved CNAs' ability to interact with behaviorally disturbed nursing home residents and produced sustained reductions in agitation. The FSM system was more effective for maintaining communication skills 6 months after training.

Nursing staff perceptions of the behaviour of older nursing home residents and decision making on restraint use: a qualitative and interpretative study

This study examined staff perceptions of the behaviour of older nursing home residents and how these perceptions govern their decision making on restraint use. Data were collected in unstructured interviews with 20 trained and untrained nursing staff from two Swiss nursing homes. Data analysis was based on Colaizzi's phenomenological method. Two main themes were extracted from the data: (i) situations in which behaviour is perceived in terms of a problem that needs to be controlled and consequently leads to restraint use; and (ii) situations in which behaviour is perceived in terms of something one has to learn to live with and consequently leads to avoidance of restraint. Staff members' choices to perceive resident's behaviour from the angle they did were clearly associated with the rights and responsibilities of both nursing staff and older people. It is concluded that the primary source of change towards the avoidance of restraint use does not necessarily lie in external factors, but in staff members themselves.

Agitated behavior in elderly nursing home residents with dementia in Japan

This study is the first investigation of the frequency of agitated behaviors in elderly dementia patients in Japanese nursing homes using the Cohen-Mansfield Agitation Inventory (J. Cohen-Mansfield, 1991). Despite major differences between Japanese and American cultures, findings were highly consistent with those of previous U.S. studies. Physically aggressive behavior, although evidenced by only 10-20% of the sample, comprised the strongest factor. A separate factor for verbal agitation also emerged. The behaviors declined during the evening and night shifts. In both the Japanese and U.S. samples, wandering, general restlessness, verbal agitation such as repetitious questioning, cursing, and complaining occurred most frequently. Another 4-point scale was used to code the degree to which agitated behavior occurred during eating, dressing, bathing, and toileting for each resident. The majority of aggressive behavior occurred in relation to personal caregiving, especially in regard to bathing. Despite major cultural differences, Japanese findings paralleled previous U.S. results.

Development and psychometric evaluation of the Environment-Behavior Interaction Code (EBIC)

BACKGROUND

Although the behavioral changes with progressive dementia are seen to increasingly depend on the environmental context until late stage disease, measurement has not reflected this interaction in real time to allow examination of antecedents to disruptive behavior.

OBJECTIVES

To develop and evaluate the psychometric properties of the Environment-Behavior Interaction Code (EBIC) for use in dementia care research with either sequential or nonsequential analyses of behavioral data.

METHOD

Development of the computer-based (sequential event format) EBIC provided an observational coding system to classify all behavior and environmental context in real time, so that the probability of social environmental antecedents to resident disruptive behavior could be estimated. A checklist (interval format) EBIC, based on the same behavioral taxonomy, was developed for clinical outcome research. A total of 158 elderly residents of dementia care units were purposively selected from three large long-term care facilities for the psychometric study components.

RESULTS

Psychometric results indicated significant (p < 0.01) known-groups validity for the disruptive behavior construct, which was defined as a composite of aversive, harmful, and high intensity neutral behavior. Interrater agreement for the event format of the EBIC was estimated by average kappa (0.65) and percentage agreement (78%). For the interval format, the mean interrater kappa was 0.80 with 96% agreement. Stability of the event format using a 2-week retest interval ranged from r= .50 (positive behavior) to r = 0.73 (negative behavior, defined as aversive + harmful). On replication with a new sample, stability was higher for positive (r = 0.92) and negative (r = 0.95) components, and for composite scores of nondisruptive (positive + low intensity neutral; r = 0.65) and disruptive (r= 0.85) behavior.

CONCLUSION

This research provided support for the reliability and validity of both event and interval EBIC formats. Measurement using the EBIC taxonomy has applicability to dementia care research questions that call for either sequential analysis of social interactions or nonsequential analysis of behavioral outcomes in intervention studies.

Natural history of aggressive behaviour in dementia

OBJECTIVE

This article analyses changes in aggressive behaviour throughout the course of dementia.

DESIGN

Prospective, 10 year, longitudinal study of aggressive behaviour in dementia, with autopsy follow-up.

SETTING

Subjects with dementia, living at home with a carer, Oxfordshire, UK.

PARTICIPANTS

Ninety-nine people with dementia (Alzheimer's disease and/or vascular dementia) who were living at home with a carer.

MEASURES

At 4-monthly intervals, the carers were interviewed about the subjects and the subjects were assessed cognitively. Subjects' behaviour was assessed using the Present Behavioural Examination. This is an investigator-based, semi-structured interview consisting of eight main sections monitoring behavioural and psychological change. Eight different aspects of aggressive behaviour were assessed in detail and comparison made with other relevant factors.

RESULTS

Verbal aggression is the most common and longest lasting form of aggressive behaviour. Aggressive resistance and physical aggression are most likely to persist until death. Intimate care is the main factor precipitating aggressive behaviour. There are no correlations between any type of aggressive behaviour and age, gender or time since onset of dementia.

CONCLUSIONS

Aggressive behaviour creates problems for carers. In general, the physical types of aggressive behaviour are most prevalent in people with more severe dementia.

Physical restraint: a descriptive study in Swiss nursing homes

This article focuses on the reasons for using physical restraints, their prevalence and nurses' experiences of their use. The data were collected by means of a questionnaire from nurses, trained nurse's aids and auxiliary staff (n = 173) in seven Swiss nursing homes. The results showed that physical restraints are used in nursing units, the mean number of restrained residents in each being 3.7 (SD 3.9). However, nursing staff did not necessarily understand and consider the term 'restraint' as a restrictive device in its negative sense. The most common reasons indicated for the use of restraint were related to the protection and safety of the residents themselves, the prevention of disturbance of other residents, and the residents' restlessness and aggressiveness. As for the reasons related to staffing, reference was made to understaffing, a lack of competence on the part of nurses, and the demands of residents, their next of kin and doctors. It was not common practice to inform the elderly residents that they would be restrained, and therefore they were not always aware of what was happening to them and why. Twenty-nine per cent of the respondents reported that the flexbility of their work was affected by the use of physical restraint.

Environmental correlates of resident agitation in Alzheimer's disease special care units

OBJECTIVE

To determine the point prevalence of agitated behaviors in a representative sample of Alzheimer's disease Special Care Units, and to determine the extent to which agitation is associated with aspects of the treatment environment.

DESIGN

A cross-sectional study in which nonparticipant observers recorded 3723 observations of resident behaviors in 53 Alzheimer's disease Special Care Units. Observational data were gathered on the physical environment and staff treatment in these settings, and resident characteristics were extracted from a data base developed in the study states by the Health Care Financing Agency. Analyses studied the association between aspects of the staff and physical environment and resident agitation levels, controlling for resident cognitive and functional status.

SETTING

Special Care Units in nursing homes in Kansas, Maine, Mississippi, and South Dakota.

PARTICIPANTS

All residents and staff of the participating units.

MAIN OUTCOME MEASURES

Eight specific agitated behaviors and two indexes of resident agitation were measured by direct observation by research assistants on three to four data collection walk-throughs in each of the study facilities.

RESULTS

The most common agitated behaviors noted were repetitive mannerisms (4.5% of resident observations) and non-loud verbal excess (3.8%). Wandering, which frequently reflects agitation, was noted in 6.5% of resident observations. The proportion of residents exhibiting an agitated behavior varied from none in some units to 38% in one unit. Independent correlates of low unit agitation levels included favorable scores on measures of the physical environment and of staff treatment activities, low rates of physical restraint use, a high proportion of residents in bed during the day, small unit size, low levels of resident functional dependency, and fewer numbers of comorbid conditions.

CONCLUSIONS

While the prevalence of agitation tends to increase as Alzheimer's disease progresses, modifiable treatment factors appear to have a strong influence on the prevalence of agitation. Both physical design and staff treatment appear to influence agitation rates, as do some measures consistent with a low stimulus approach to Alzheimer's care.

The relationship between premorbid life-style and wandering behaviors in institutionalized people with dementia

Forty-nine ambulatory residents participated in a study conducted to determine the relationship between premorbid life-style, work, and ways of handling stress, and wandering in dementia units. The sample consisted of 23 males and 26 females with a mean age of 79. Family members responded to open-ended questionnaires that asked about premorbid leisure activities, hobbies, exercise, stress management, type of employment and social interactions. Activities were ranked according to energy expended on the Metabolic Cost of Activities (MET) Scale. No activity equaled Inactive (0); 1.5-2 METS equaled Mildly Active (1), 2-3 METS equaled Moderately Active (2), and 3-4 METS equaled Very Active (3). Subjects were observed three times for one-hour intervals on each of three shifts (day, evening, night) at randomly selected times to assess wandering behavior. Behavior was logged every five minutes. The subjects' most frequent conditions were awake (21%), alone (20%), and in their own rooms (17%). Twenty-four (50%) of the subjects were observed pacing, and 16 (33%) were agitated/restless at some point in time. Statistical analyses showed no significant correlations between premorbid life-style variable rankings and the amount of time spent standing, walking and pacing. The findings suggest that wandering behavior is not influenced by premorbid life-styles.

Physical aggressive resident behavior during hygienic care

Management of aggressive behavior has been identified as a concern for nursing staff who provide institutional care for cognitively impaired elderly. The Omnibus Reconciliation Act (OBRA '87) mandates a trial reduction in the use of chemical and physical restraints, and the development of nursing interventions for the management of behavioral disorders of institutionalized cognitively impaired elderly. Most skilled nursing facilities, however, are limited in their ability to provide environmental and behavioral programs to manage aggressive patient behavior. For the purposes of this study, physically aggressive behavior was identified as threatened or actual aggressive patient contact which has taken place between a patient and a member of the nursing staff. This study explored the nursing staff's responses to patient physical aggression and the effects that physical aggression had on them and on nursing practice from the perspective of the nursing staff. Nursing staff employed on one Dementia Special Care Unit (DSCU) were invited to participate. Interviews with nursing staff were analyzed using qualitative descriptive methods described by Miles and Huberman (1994). Nursing staff reported that they were subjected to aggressive patient behaviors ranging from verbal threats to actual physical violence. Nursing staff reported that showering a resident was the activity of daily living most likely to provoke patient to staff physical aggression. The findings revealed geropsychiatric nursing practices for the management of physically aggressive residents, and offered recommendations for improving the safety of nursing staff and residents on a secured DSCU.

Toileting: a biobehavioral challenge in Alzheimer's dementia care

As the trajectory of Alzheimer's disease (AD) progresses, problems with toileting become evident. This research addresses the range and variation of toileting problems, management strategies used by family and employed caregivers, and interactive and contextual conditions associated with toileting. Qualitative ethology was used to analyze data from over 120 hours of participant observation at an Alzheimer's Day Care Center, in clients' homes, and support groups; and interviews with families (n = 16) and staff members (n = 13). Toileting emerged as a complex event with many stages, as unaesthetic and unpleasant for caregivers and clients, and as occasionally resulting in catastrophic reactions. Caregivers read cues and interpret toileting behaviors. They provide physical and cognitive assistance while attempting to avoid accidents and catastrophic events. Client, staff member, and contextual variables affect toileting events. Recommendations for practice and research are proposed.

Psychiatric nursing outcome research: the state of the science

A review of the nursing literature from 1989 to 1994 indicates that few psychiatric nursing studies are published in the major nursing research journals. The psychiatric specialization literature includes a large number of studies that are classified as either outcome studies or could serve as building blocks for future outcome studies. Few studies build on prior research, resulting in a weak scientific basis for evaluating the outcomes of psychiatric nursing care. Strategies for increasing the quantity and quality of psychiatric nursing outcome research are presented.

Disturbing behaviors in demented elders: a concept synthesis

This article describes the use of concept synthesis, as defined by Walker and Avant, to extract meaningful syndromes of disturbing behaviors as they are manifested in demented elders. The process resulted in the identification of five distinct behavioral clusterings: Aggressive Psychomotor Behavior, Nonaggressive Psychomotor Behavior, Verbally Aggressive Behavior, Passive Behavior and Functionally Impaired Behavior. These synthesized concepts are an initial attempt at clarifying nursing perspective on disturbing behaviors in dementia.

The influence of environmental factors in incidents of disruptive behavior

1. Disruptive behavior is an annoying and potentially dangerous problem in most nursing homes. Disruptive behaviors can be both physical and verbal. 2. Changes associated with termination of disruptive behaviors included the reduction of external environmental stimuli, reduction of perceived threats to the patient's personal freedom and fulfillment of basic physical needs, fulfillment of needs for interpersonal support, a simple request to the disruptive person that the behavior be discontinued, provision for increased freedom by releasing the person from a gerichair or wheelchair with rollbar, separation of residents involved in disputes, and resolution of disputes over belongings. 3. In order to initiate changes that will reduce the frequency of such behavior or mitigate its harmful effects, nurses must have a better understanding of how environmental factors influence the evolution of disruptive episodes and plan appropriate and specific nursing interventions.

Behavioral symptoms in dementia: an update

A descriptive literature review was done to identify research conducted in both community and institutional settings and published from 1986 to 1993 on the correlates of behavioral symptoms associated with dementia. Critical appraisal and synthesis of the 40 studies revealed theoretical and methodological problems that tempered conclusions about the relationships between behavioral symptoms and the correlates under study. While direct relationships were found in studies in which relationships between behavioral symptoms and cognitive impairment and contextual factors were examined, contradictory results were found in studies of demographic and functional variables. Recommendations for research-based practice are advanced, including the development and testing of alternatives to physical and chemical restraints in the care of persons with dementia.

Managing disruptive responses to bathing by elderly residents. Strategies for the cognitively impaired

1. Persons with altered cognition are more prone to display inappropriate behaviors because of decreased ability to accurately interpret environmental cues, and increased frustration in combination with reduced inhibition. 2. Disruptive and agitated behaviors are commonly associated with the provision of assistance with activities of daily living, particularly bathing and dressing. 3. A preventive approach intended to reduce the occurrence of distress and disruptive behaviors in cognitively impaired residents during showering and bathing respects long-standing routines and preferences of the patient.

Risk profiles for nursing home placement of rural elderly: a cluster analysis of psychogeriatric indicators

In an effort to better understand the clinical and functional status of patients served by our Rural Elder Outreach Program, more effectively identify risk groups, and more efficiently target services, we performed a cluster analysis on 92 older adults served by our program. The first cluster included patients with very poor health, mild cognitive impairment, very high care demands, and migrating toward active risk for institutionalization. The second cluster included patients with poor physical but good mental health, intact cognition, high care demands, and at passive risk. The third cluster comprised patients with high functional, physical, and cognitive impairment, intensive care demands, moderate mental health problems, poor insight into their situation, and at active risk for institutionalization.

Effects of relaxing music on agitation during meals among nursing home residents with severe cognitive impairment

Relaxing music was hypothesized to buffer the general noise level typically found in dining rooms of nursing homes, exert a calming effect, and thus reduce agitated behaviors among residents with severe cognitive impairment. Twenty-nine nursing home residents with severe cognitive deficits participated in a 4-week protocol in which, following baseline observations (week 1), relaxing music was introduced (week 2), removed (week 3), and reintroduced (week 4). Subjects were observed in terms of total number of behaviors of the Cohen-Mansfield Agitation Inventory present during a given week, and the number of behaviors present on the subscales of aggressive, physically nonaggressive, verbally agitated, and hiding/hoarding behaviors. Significant reductions were observed on the cumulative incidence of total agitated behaviors (63.4%); as well as the cumulative incidence of physically nonaggressive behaviors (56.3%) and verbally agitated behaviors (74.5%). No significant reductions were noted in terms of aggressive behaviors and hiding/hoarding behaviors. Where significant reductions were achieved, a distinct pattern was observed. Agitation decreased during week 2, increased again during week 3, only to decrease again in week 4. In addition, variance effects were noted as well, as ranges and standard deviations of agitated behaviors narrowed over time. These findings are interpreted within Hall and Buckwalter's (1988) model of a progressively lowered stress threshold among dementia patients.
