Can Doll therapy preserve or promote attachment in people with cognitive, behavioral, and emotional problems? A pilot study in institutionalized patients with dementia

Doll therapy for improving behavior, psychology and cognition among older nursing home residents with dementia: A systematic review and meta-analysis

OBJECTIVE

To explore the effectiveness of doll therapy (DT) on behavior, psychology and cognition among older nursing home residents with dementia.

METHODS

A systematic review and meta-analysis was conducted. Subgroup analyses were performed to determine whether the intervention characteristics influenced effect sizes.

RESULTS

Ten studies met the inclusion criteria and were selected for qualitative and quantitative synthesis. The overall methodological quality was relatively high. DT significantly improved all behaviors [SMD=-0.42, P=0.01], including agitation [SMD=-0.94, P<0.001], apathy, irritability and wandering, and psychological states (i.e., pleasure, anxiety and depression). However, there was no significant difference in the improvement of cognition. Subgroup analyses revealed that the DT process employing empathy dolls and coordinating with caregivers was more beneficial for improving all behaviors (P=0.01; P=0.02).

CONCLUSION

DT significantly reduced behavioral and psychological disturbances among older nursing home residents with dementia. Specifically, administering empathy dolls and coordinating with caregivers may be the most appropriate and effective option.

This article illustrates the NMIs implemented, how they are carried out and how they are evaluated as part of the Bien vieillir project at Nice University Hospital.

[Quality of life in institutionalized older adults with moderate to severe major neurocognitive disorder: Effect of Doll therapy]

BACKGROUND AND OBJECTIVES

Major neurocognitive disorder is characterized by progressive cognitive impairment, a decrease in the person's ability to perform activities of daily living and the appearance of psychological and behavioral symptoms that lead to a deterioration in the quality of life and progression towards institutionalization. The most common management of major neurocognitive disorder is pharmacological therapy that mitigates or slow progressive deterioration and symptom control. The objective of this study was to establish the effect of a nursing intervention based on Doll therapy, compared to conventional care on the quality of life of older adults with moderate to severe major neurocognitive disorder institutionalized in nursing homes in the city of Medellín, Colombia.

METHODS

Pilot experimental study with two groups and pretest post-test measurement. The sample consisted of 26 institutionalized elderly adults with advanced-stage major neurocognitive disorder, randomly assigned to each group. The experimental group received Doll therapy, based nursing therapy, while the comparison group continued to receive conventional therapy according to the institution's protocol. The QUALID instrument was used, which was evaluated by professionals external to the care centers.

RESULTS

The comparison of the groups, before and after the intervention, indicates that the experimental group showed a positive effect on quality of life, supported by the statistical significance of the data, with a moderate effect.

CONCLUSIONS

The Doll therapy as a non-pharmacological therapy has a positive effect on the quality of life of patients with moderate to severe major neurocognitive disorder, which constitutes a contribution to strengthen the knowledge associated with the effects or this intervention.

The ethics of pet robots in dementia care settings: Care professionals' and organisational leaders' ethical intuitions

BACKGROUND

Pet robots are gaining momentum as a technology-based intervention to support the psychosocial wellbeing of people with dementia. Current research suggests that they can reduce agitation, improve mood and social engagement. The implementation of pet robots in care for persons with dementia raises several ethical debates. However, there is a paucity of empirical evidence to uncover care providers' ethical intuitions, defined as individuals' fundamental moral knowledge that are not underpinned by any specific propositions.

OBJECTIVES

Explore care professionals' and organisational leaders' ethical intuitions before and when implementing pet robots in nursing homes for routine dementia care.

MATERIALS AND METHODS

We undertook a secondary qualitative analysis of data generated from in-depth, semi-structured interviews with 22 care professionals and organisational leaders from eight nursing homes in Ireland. Data were analysed using reflexive thematic analysis. Ethical constructs derived from a comprehensive review of argument-based ethics literature were used to guide the deductive coding of concepts. An inductive approach was used to generate open codes not falling within the pre-existing concepts.

FINDINGS

Ethical intuitions for implementing pet robots manifested at three levels: an (1) individual-relational, (2) organisational and (3) societal level. At the individual-relational level, ethical intuitions involved supporting the autonomy of residents and care providers, using the robots to alleviate residents' social isolation, and the physical and psychosocial impacts associated with their use. Some care providers had differing sentiments about anthropomorphizing pet robots. At the organisational level, intuitions related to the use of pet robots to relieve care provision, changes to the organisational workflow, and varying extents of openness amongst care providers to use technological innovations. At the societal level, intuitions pertained conceptions of dementia care in nursing homes, and social justice relating to the affordability and availability of pet robots. Discrepancies between participants' ethical intuitions and existing philosophical arguments were uncovered.

CONCLUSION

Care professionals and organisational leaders had different opinions on how pet robots are or should be implemented for residents with dementia. Future research should consider involving care practitioners, people with dementia, and their family members in the ethics dialogue to support the sustainable, ethical use of pet robots in practice.

Doll Therapy Intervention Reduces Challenging Behaviours of Women with Dementia Living in Nursing Homes: Results from a Randomized Single-Blind Controlled Trial

Background: Doll therapy (DT) is a non-pharmacological intervention for the treatment of the behavioural and psychological symptoms of dementia (BPSD). We designed a single-blind randomized controlled trial of the 30-day efficacy of DT in reducing the BPSD, professional caregivers’ distress and patients’ biomarkers of stress, and in improving the exploration and caregiving behaviours. Methods: We randomly assigned 134 women with moderate-to-severe dementia living in nursing homes (NHs) to a DT intervention (DTI, 67) or a sham intervention with a cube (SI, 67). Results: From the first to the 30th session, the DTI group showed a significant decrease in the Neuropsychiatric Inventory-NH (NPI-NH) total score and in the NPI-NH-Distress score compared to the SI group (both p < 0.001). We observed a greater interest in the doll than in the cube, a greater acceptance of a separation from the nurse among DTI participants, and caregiving and exploratory behaviours towards the doll. There were no differences between the groups in the stress biomarkers. Conclusions: Consistent with attachment theory, our findings support the 30-day efficacy of DT, as this non-pharmacological intervention promotes perceptions of security by creating a situation in which patients feel confident and engaged in a caregiving relationship with the doll and reduces the challenging behaviours that are stressful for professional caregivers.

Managing feeding needs in advanced dementia: perspectives from ethics of care and ubuntu philosophy

The response to feeding needs in advanced dementia patients is a subject of ethical inquiry. Advanced dementia is the debilitating result of a range of neurodegenerative diseases. As this terminal illness progresses, patients develop mild to severe dysphagia that can make swallowing difficult. Of the two available options, artificial tube feeding or oral hand feeding, an estimated one-third of these patients will receive artificial tube feeding. However, observational studies have failed to validate the clinical benefits of tube feeding. Ethics of care, the feminist philosophical perspective, and Ubuntu philosophy offer arguments for the choice of oral hand-feeding as a preferrable first option by caregivers as far as possible. These moral theories acknowledge that human beings can be dependent for long periods, mostly early and later years of life. Both views reflect an approach that draws people into a system of interdependent caring relationships. They encourage hand feeding as a way of exhibiting solidarity and respecting human dignity even at the end of life.

Effect of Doll Therapy in Behavioral and Psychological Symptoms of Dementia: A Systematic Review

(1) Background: Behavioral and psychological symptoms of dementia (BPSD) are a threat for people with dementia and their caregivers. Doll therapy is a non-pharmacological person-centered therapy to promote attachment, company, and usefulness with the aim of minimizing challenging behaviors. However, the results are not clear. (2) Objective: To know the effectiveness of doll therapy in reducing behavioral and psychological symptoms of people with dementia at a moderate-severe phase. (3) Methodology: The systematic review was informed according to the criteria established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Searches were conducted in eight databases: Cochrane, PubMed, Web of Science, Cinahl, Embase, Lilacs, PeDro, and Scopus before October 2021. Studies were selected when they accomplished the simple majority of Consolidated Standards of Reporting Trials (CONSORT). The risk of bias was appraised with the Cochrane Collaboration Risk of Bias Tool. The review protocol was recorded in Inplasy:1539. (4) Results: The initial search strategy showed 226 relevant studies, 7 of which met the eligibility criteria. In the included studies, a total number of 295 participants (79% female) with a mean age of 85 years were enrolled. There was found to be a reduction in challenging and aggressive behaviors, the participants were less rough and irritable, and their communication skills and emotional state were also improved. (5) Conclusion: Our findings suggest that doll therapy improves the emotional state of people with dementia, diminishes disruptive behaviors, and promotes communication. However, randomized studies with a larger sample size and higher methodological rigor are needed, as well as follow-up protocols in order to reaffirm these results.

The doll therapy as a first line treatment for behavioral and psychologic symptoms of dementia in nursing homes residents: a randomized, controlled study

Background

Patients living with dementia are severely affected by the development of behavioral and psychologic symptoms (BPSD) which represent a burden for patients and caregivers. The use of psychotropic drugs in the control of BPSD is widely diffused, however the use of a first line non-pharmacologic approach is highly recommended.

Here we evaluate the effect of doll therapy (DT) in the management of BPSD, on the reduction of caregiver burden and delirium incidence in nursing home residents by a randomized controlled trial.

Methods

We enrolled fifty-two nursing homes residents living with dementia and BPSD. Subjects were randomized to DT (26) or standard treatment (ST, 26), we measured BPSD, caregiver burden and delirium with standard clinical scales at baseline, after 45 and 90 days.

In order to evaluate the presence of BPSD we used Neuropsychiatric Inventory (NPI) scale and the A.Di.CO scale, the caregiver burden was measured by the Greutzner scale and delirium by the Confusion Assessment Method (CAM) scale.

Results

DT was more effective in reducing agitation and aggressiveness as respect to ST. Moreover DT globally reduced the presence of BPSD as dysphoria, wandering and apathy. We observed a significant reduction of the professional caregiver burden and the incidence of delirium was significantly reduced in subjects treated with DT.

Conclusions

We show that DT is more effective that ST in the control of BSPD in patients affected by moderate to severe dementia. Moreover we suggest that DT may effective in reducing the incidence of delirium.

A Minimal Design of a Human Infant Presence: A Case Study Toward Interactive Doll Therapy for Older Adults With Dementia

We introduce a minimal design approach to manufacture an infant-like robot for interactive doll therapy that provides emotional interactions for older people with dementia. Our approach stimulates their imaginations and then facilitates positive engagement with the robot by just expressing the most basic elements of humanlike features. Based on this approach, we developed HIRO, a baby-sized robot with an abstract body representation and no facial features. The recorded voice of a real human infant emitted by robots enhances the robot’s human-likeness and facilitates positive interaction between older adults and the robot. Although we did not find any significant difference between HIRO and an infant-like robot with a smiling face, a field study showed that HIRO was accepted by older adults with dementia and facilitated positive interaction by stimulating their imagination. We also discuss the importance of a minimal design approach in elderly care during post–COVID-19 world.

[Design and validation of two scales about attitudes and knowledge regarding doll therapy in dementia]

INTRODUCTION

Non-pharmacological interventions are often the subject of debate in the scientific field. Therefore, it is essential to know the attitudes that health professionals have towards the novel Doll Therapy in Dementia (DTD). The objective of this study was to design and validate two questionnaires to find out the attitudes and knowledge on DTD in health professionals.

MATERIAL AND METHODS

A total of 120 Spanish-speaking Geriatrics and Gerontology professionals, with a mean age of 38.3 years (DT = 10.99), participated, mostly women (88.3%). A questionnaire (TCM_DEMCO) on knowledge about the DTD and a questionnaire (TCM_DEMAC) on attitudes towards the DTD were designed and applied. The construct validity was assessed by exploratory factor analysis, and reliability was calculated using Cronbach's α.

RESULTS

The exploratory factor analysis of the TCM_DEMCO questionnaire retained 10 items in 5 factors ("environment and dementia", "therapeutic application", "activities", "methodology" and "benefits and implications") that explained 70.1% of the total variability, giving a Cronbach α coefficient value > 0.50. The exploratory factor analysis of the TCM_DEMAC questionnaire retained 10 items in two factors ("positive attitudes" and "negative attitudes") that explained 61.2% of the total variability, giving a Cronbach α value > 0.85.

CONCLUSIONS

Both questionnaires are a brief tool to learn about the attitudes and knowledge of Spanish-speaking Geriatrics and Gerontology professionals in matters of DTD. The reliability and validity analyses performed showed good psychometric properties of these tools.

Doll therapy intervention for women with dementia living in nursing homes: a randomized single-blind controlled trial protocol

BACKGROUND

Doll therapy is a non-pharmacological intervention for people with dementia aimed to reduce distressing behaviours. Reliable results on the efficacy of Doll therapy for people with dementia are needed. The concept of attachment theorised by Bowlby has been proposed to explain the Doll therapy process, but it has not been proven to influence the response to doll presentation.

METHODS/DESIGN

This single-blind, randomised controlled trial will involve people with dementia living in nursing homes of the Canton Ticino (Switzerland). Participants will be randomised to one of two interventions: Doll Therapy Intervention or Sham Intervention with a non-anthropomorphic object, using a 1:1 allocation ratio. The two interventions will consist of 30 daily sessions lasting an hour at most, led by a trained nurse for an hour at most. We will enrol 64 participants per group, according to power analysis using an estimated medium effect size (f = 0.25), an alpha level of 0.05, and a power of 0.8. The primary goal is to test the efficacy of the Doll Therapy Intervention versus the Sham Intervention as the net change in the following measures from baseline to 30 days (blinded outcomes): the Neuropsychiatric Inventory-Nursing Home administered by a trained psychologist blinded to group assignment, the professional caregivers' perceived stress scale of the Neuropsychiatric Inventory-Nursing Home, patients' physiological indices of stress (salivary cortisol, blood pressure and heart rate) and interactive behaviours. The secondary goal is to assess the relationship between attachment styles of people with dementia (detected by means of the Adult Attachment Interview to the patients' offspring) and their caregiving behaviours shown during the Doll Therapy Intervention.

DISCUSSION

This is the first single-blind, randomised controlled trial on the efficacy of Doll therapy for dementia and an explanatory model of the response of people with dementia to doll presentation.

Enhancing theory of mind in behavioural variant frontotemporal dementia with transcranial direct current stimulation

Behavioural variant frontotemporal dementia (bvFTD) is a form of frontotemporal degeneration characterized by early changes in personality, emotional blunting, and/or loss of empathy. Recent research has highlighted that these features may be at least partially explained by impairments in the theory of mind (ToM; i.e., the ability to understand and predict other people's behaviour by attributing independent mental states to them). The aim of this randomized, double-blind, placebo-controlled study was to test the hypothesis that transcranial direct current stimulation (tDCS) over the medial frontal cortex (MFC) selectively enhances communicative intention processing, a specific ToM ability. Using a single-session online design, we administered a ToM task that measures the ability to represent other people's private and communicative intentions during active or sham tDCS to 16 bvFTD patients. To assess the impact of dementia on performance on the ToM task, we included 16 age-matched healthy volunteers who were asked to perform the entire experimental ToM task. BvFTD is characterized by an impairment in the comprehension of both communicative and private intentions relative to a healthy control group and by a disproportional impairment in communicative intention compared with private intention processing. Significant and selective accuracy improvement in the comprehension of communicative intentions after active stimulation was observed in patients with bvFTD. This is the first study that analyses ToM ability in patients with bvFTD using tDCS stimulation. Our findings could potentially contribute to the development of an effective, noninvasive brain stimulation treatment of ToM impairments in patients with bvFTD.

Comparison of the efficacy of gesture-verbal treatment and doll therapy for managing neuropsychiatric symptoms in older patients with dementia

BACKGROUND

The prevalence of neuropsychiatric symptoms (NPS) diminishes the quality of life and increases the care burden in patients with dementia. Despite the clinical importance of dementia-associated NPS, no protocols for treating NPS are already well established. Attention has turned to the effectiveness of nonpharmacological treatments for NPS since their potential safe alternative to pharmacotherapy.

OBJECTIVE

This study is aimed to compare the effects in older individuals with dementia living in a residential care, of two intervention programs, the gesture-verbal treatment (GVT), a treatment implemented by us on a previous method for word retrieval in individuals with aphasia, and the better-known doll therapy (DT). The GVT would act on both receptive and expressive language skills, the DT on attachment and emotional connections.

METHODS

We evaluated NPS by the neuropsychiatric inventory in a total of 30 patients divided into 3 groups, the GVT, the DT, and control groups, using a pre-post design. The treatment groups completed 12-week nonpharmacological interventions in addition to standard rehabilitative therapies, while the control group participated only in standard rehabilitative therapies.

RESULTS

The DT group showed significant improvements in agitation, irritability, apathy, depression, and delusions relative to controls. The GVT group showed significant improvements in apathy and depression with respect to controls. The DT intervention ameliorated symptoms of agitation compared to the GVT intervention whereas the GVT intervention improved apathy compared to the DT intervention.

CONCLUSION

Improved understanding of the potential therapeutic benefits of different treatments for neuropsychiatric symptoms is crucial for establishing nonpharmacological interventions in dementia.

Using dolls for therapeutic purposes: A study on nursing home residents with severe dementia

OBJECTIVES

Among the psychosocial interventions intended to reduce the behavioral and psychological symptoms of dementia (BPSD), doll therapy (DT) is increasingly used in clinical practice. Few studies on DT have been based on empirical data obtained with an adequate procedure; however, none have assessed its efficacy using an active control group, and the scales used to assess changes in BPSD are usually unreliable. The aim of the present study was to measure the impact of DT on people with severe dementia with a reliable, commonly used scale for assessing their BPSD, and the related distress in formal caregivers. Effects of DT on the former's everyday abilities (ie, eating behavior) were also examined.

METHOD

Twenty-nine nursing home residents aged from 76 to 96 years old, with severe dementia (Alzheimer's or vascular dementia), took part in the experiment. They were randomly assigned to an experimental group that used dolls or an active control group that used hand warmers with sensory characteristics equivalent to the dolls. Benefits of DT on BPSD and related formal caregiver distress were examined with the Neuropsychiatric Inventory. The effects of DT on eating behavior were examined with the Eating Behavior Scale.

RESULTS

Only the DT group showed a reduction in BPSD scores and related caregiver distress. DT did not benefit eating behavior, however.

CONCLUSIONS

This study suggests that DT is a promising approach for reducing BPSD in people with dementia, supporting evidence emerging from previous anecdotal studies.

Animal-assisted intervention for individuals with cognitive impairment: A meta-analysis of randomized controlled trials and quasi-randomized controlled trials

The aim of this meta-analysis was to systematically examine the efficacy of animal-assisted intervention (AAI) for cognitive impairment patients. PubMed, Embase, the Cochrane library, PsycINFO, and Web of Science databases were searched up to June 2017 to collect studies related to AAI conducted in patients with cognitive impairment. Five randomized controlled trials (RCTs) and five quasi-randomized controlled trials (quasi-RCTs) involving 413 participants were included. Compared with control groups, AAI groups exhibited significantly fewer behavioral and psychological symptoms of dementia (BPSD), especially depression and agitation. In both the short and long term, AAI had beneficial effects on BPSD in cognitive impairment patients. However, no significant improvements were found in daily living activities, quality of life or cognitive score. The present meta-analysis showed that AAI can be effective in reducing BPSD in patients with cognitive impairment.

Cognitive Training in a Large Group of Patients Affected by Early-Stage Alzheimer's Disease can have Long-Lasting Effects: A Case-Control Study

Introduction: Cognitive training in Alzheimer's disease (AD) has recently started to demonstrate its efficacy. We used our ‘puzzle-like’ task (GEO) as training for a large group of early-stage AD patients, to detect its effects over time.

Method: AD patients (N = 40) and healthy controls (N = 40) were involved. Participants were administered the Geographical Exercises for cognitive Optimization (GEO) task. Participants underwent individual sessions with GEO three times a week for 2 months, and then their performance was recorded again. Lastly, at the 12-month follow-up the GEO task was administered for the last time.

Results: Patients’ scores were significantly worse than controls’ scores only on a few neuropsychological tests. We ran a repeated measures GLM by considering groups’ performance on the GEO task at the assessment points. Results showed a significant main effect of group, and a significant effect of the interaction between group and time: patients’ performances both at the end of the training and at the follow-up were virtually identical to controls’ performances.

Conclusions: Patients effectively acquired new procedural abilities, and their achievements were stable at follow-up. This study suggests the GEO is a useful strategy for cognitive training in AD, and should prompt further investigations about the degree of generalisability of patients’ acquired skills.
