Group reminiscence intervention in Taiwanese elders with dementia

Digital Storytelling Intervention for Enhancing the Social Participation of People With Mild Cognitive Impairment: Co-Design and Usability Study

BACKGROUND

Community-based social participation has shown promise in delaying cognitive decline in older adults with mild cognitive impairment (MCI) who are at risk of developing dementia. Although group storytelling interventions have proven effective, the need for a skilled workforce to support people with MCI can limit broader community implementation. Technology-based interventions may offer a solution to this limitation by replicating the abilities of therapists.

OBJECTIVE

This study aims to co-design a digital storytelling intervention and evaluate its usability.

METHODS

This co-design process involved 3 stages, engaging people with MCI (n=12), their caregivers (n=4), and therapists (n=5) in Beijing, China. In the first stage, we used card sorting and voting methods to identify potential incentives for social participation and target the specific abilities that people with MCI wanted to enhance. In the second stage, we conducted brainstorming sessions with people with MCI and their caregivers to identify the potential features of a digital storytelling application named Huiyou ("meeting new friends" in Chinese). Finally, we assessed Huiyou's usability with people with MCI and therapists, leading to iterative improvements based on the usability findings.

RESULTS

We uncovered a crucial link between boosting the self-confidence of people with MCI and their ability to address social participation challenges. Notably, we identified memory improvement and enhanced language expression as key factors for effective communication with grandchildren. Subsequently, participants suggested features and interfaces to address these challenges, leading to the development of Huiyou, a group-based digital storytelling application featuring functions such as generating story materials, conducting memory retrieval activities, and sharing stories. It received an "excellent" rating in the User Experience Questionnaire benchmark, displaying high levels of attractiveness, dependability, stimulation, and novelty. People with MCI achieved an average task completion rate of 87% (n=19; SD 0.13) of the 22 tasks. However, feedback from people with MCI and therapists highlighted usability issues in navigation, activity management, user interface, and feature optimization, indicating a need for improved accessibility and efficiency.

CONCLUSIONS

The co-design approach contributed to developing the Huiyou prototype, supporting community-based social participation. User feedback highlighted the potential of Huiyou to enhance well-being and facilitate meaningful social interactions while maintaining crucial existing relationships.

Effect of reminiscence on cognitive impairment and depression in haemodialysis patients

BACKGROUND

Cognitive impairment and depression are common problems in haemodialysis patients.

AIM

The present study was carried out to determine the impact of reminiscence on cognitive impairment and depression in haemodialysis patients.

DESIGN

This clinical trial (2016) was conducted with a pretest-posttest design on the haemodialysis patients of hospitals in Shahrud, Iran.

PARTICIPANTS AND MEASUREMENTS

Block random sampling was used to investigate the patients' cognitive status and Beck's Depression Scale were administered among 75 patients divided into intervention (given 12 sessions of Stinson's group reminiscence), control (group discussions), and sham (without any intervention) groups before, immediately and 30 days after the intervention.

RESULTS

Immediately and 30 days after the intervention, the cognitive score was significantly higher in the reminiscence group than the control (p < 0.001) and sham (p < 0.001) groups. Immediately after the intervention, the depression score was significantly lower in the reminiscence group than the control (p = 0.011) and sham (p < 0.001) groups. Also, immediately and 30 days after the intervention, the depression score was significantly lower in the reminiscence group than the control (p = 0.031) and sham (p < 0.001) groups.

CONCLUSIONS

The findings showed that reminiscence increased the cognitive health score and improved depression in haemodialysis patients. Therefore, reminiscence protocols can be utilized as an independent routine nursing care measure for improving cognitive status and depression in haemodialysis patients.

The Effects of a Recollection-Based Occupational Therapy Program of Alzheimer's Disease: A Randomized Controlled Trial

Considering the high socioeconomic costs related to the increasing number of dementia patients and their poor quality of life and that of their families, it is important to identify the condition early on and provide an appropriate intervention. This study organized a recollection-based occupational therapy program: a nonpharmacological intervention consisting of five categories of activities (physical, horticultural, musical, art, and instrumental activity of daily living; IADL) and applied it to those having a mild stage of Alzheimer's disease. The experimental group participated in a total of 24 sessions--five times per week for one hour per session--while the control group took part in regular activities offered by the existing facilities. The experimental group presented improved cognitive functions, reduced depression, and enhanced quality of life; the two groups showed a statistically significant difference in every category. This study is meaningful in that it made a cognitive stimulation program concerning five different categories, implemented it for people suffering mild dementia, and confirmed positive outcomes. If a systemic version of the program is offered in dementia care facilities, it is expected to make a considerable contribution to the care of dementia patients.

Improving mental health and reducing antipsychotic use in people with dementia in care homes: the WHELD research programme including two RCTs

Background

The effective management of agitation and other neuropsychiatric and behavioural symptoms in people with dementia is a major challenge, particularly in care home settings, where dementia severity is higher and there is limited training and support for care staff. There is evidence for the value of staff training and the use of psychosocial approaches; however, no intervention currently exists that combines these elements into an intervention that is fit for purpose and effective in these settings based on evidence from a randomised controlled trial.

Objective

The objective was to develop and evaluate a complex intervention to improve well-being, reduce antipsychotic use and improve quality of life in people with dementia in care homes through person-centred care, management of agitation and non-drug approaches.

Design

This was a 5-year programme that consisted of six work packages. Work package 1 consisted of two systematic reviews of personalised psychosocial interventions for behavioural and psychological symptoms for people with dementia in care homes. Work package 2 consisted of a metasynthesis of studies examining implementation of psychosocial interventions, in addition to developing a draft Well-being and Health for people with Dementia (WHELD) programme. Work package 3 consisted of a factorial study of elements of the draft WHELD programme in 16 care homes. Work package 4 involved optimisation of the WHELD programme based on work package 3 data. Work package 5 involved a multicentre randomised controlled trial in 69 care homes, which evaluated the impact of the optimised WHELD programme on quality of life, agitation and overall neuropsychiatric symptoms in people with dementia. Work package 6 focused on dissemination of the programme.

Setting

This programme was carried out in care homes in the UK.

Participants

Participants of this programme were people with dementia living in care homes, and the health and care professionals providing treatment and care in these settings.

Results

Work package 1: reviews identified randomised controlled trials and qualitative evidence supporting the use of psychosocial approaches to manage behavioural symptoms, but highlighted a concerning lack of evidence-based training manuals in current use. Work package 2: the meta-analysis identified key issues in promoting the use of interventions in care homes. The WHELD programme was developed through adaptation of published approaches. Work package 3: the factorial trial showed that antipsychotic review alone significantly reduced antipsychotic use by 50% (odds ratio 0.17, 95% confidence interval 0.05 to 0.60). Antipsychotic review plus social interaction significantly reduced mortality (odds ratio 0.36, 95% confidence interval 0.23 to 0.57), but this group showed significantly worse outcomes in behavioural and psychological symptoms of dementia than the group receiving neither antipsychotic review nor social interaction (mean difference 7.37 symptoms, 95% confidence interval 1.53 to 13.22 symptoms). This detrimental impact was reduced when combined with social interaction (mean difference –0.44 points, 95% confidence interval –4.39 to 3.52 points), but with no significant benefits for agitation. The exercise intervention significantly improved neuropsychiatric symptoms (mean difference –3.58 symptoms, 95% confidence interval –7.08 to –0.09 symptoms) but not depression (mean difference –1.21 points, 95% confidence interval –4.35 to 1.93 points). Qualitative work with care staff provided additional insights into the acceptability and feasibility of the intervention. Work package 4: optimisation of the WHELD programme led to a final version that combined person-centred care training with social interaction and pleasant activities. The intervention was adapted for delivery through a ‘champion’ model. Work package 5: a large-scale, multicentre randomised controlled trial in 69 care homes showed significant benefit to quality of life, agitation and overall neuropsychiatric symptoms, at reduced overall cost compared with treatment as usual. The intervention conferred a statistically significant improvement in quality of life (Dementia Quality of Life Scale – Proxy z-score of 2.82, mean difference 2.54, standard error of measurement 0.88, 95% confidence interval 0.81 to 4.28, Cohen’s d effect size of 0.24; p = 0.0042). There were also statistically significant benefits in agitation (Cohen-Mansfield Agitation Inventory z-score of 2.68, mean difference –4.27, standard error of measurement 1.59, 95% confidence interval –7.39 to –1.15, Cohen’s d effect size of 0.23; p = 0.0076) and overall neuropsychiatric symptoms (Neuropsychiatric Inventory – Nursing Home version z-score of 3.52, mean difference –4.55, standard error of measurement 1.28, 95% confidence interval –7.07 to –2.02, Cohen’s d of 0.30; p < 0.001). The WHELD programme contributed to significantly lower health and social care costs than treatment as usual (cost difference –£4740, 95% confidence interval –£6129 to –£3156). Focus groups were conducted with 47 staff up to 12 months after the end of work package 5, which demonstrated sustained benefits. Work package 6: the outputs of the programme were translated into general practitioner workshops and a British Medical Journal e-learning module, an updated national best practice guideline and a portfolio of lay and care home outreach activities.

Limitations

Residents with dementia were not involved in the qualitative work.

Conclusions

The WHELD programme is effective in improving quality of life and reducing both agitation and overall neuropsychiatric symptoms in people with dementia in care homes. It provides a structured training and support intervention for care staff, with lower overall costs for resident care than treatment as usual.

Future work

It will be important to consider the long-term sustainability of the WHELD programme and cost-effective means of long-term implementation.

A systematic review and meta-analysis on the effect of reminiscence therapy for people with dementia

BACKGROUND

The main objective of this study was to conduct a meta-analysis to identify the effects of reminiscence therapy in people with dementia (PWD).

METHODS

A systematic search of randomized controlled trials (RCTs) was conducted using bibliographic databases. A total of 157 original published studies were identified in the search, and 24 complete articles were included in the final review to check for the level of evidence. Two of the study authors independently assessed the quality of the included studies using the "Risk of Bias" (ROB) tool developed by the Cochrane Collaboration. Depression, quality of life, and behavioral and psychological symptoms of dementia (BPSD) were selected to measure the effect of reminiscence therapy. To determine the effects of reminiscence therapy on these variables, each individual study was analyzed using Comprehensive Meta-Analysis Software® (Biostat, Englewood, NJ, USA).

RESULTS

The overall effect size was presented using standardized mean differences (SMDs) and 95% confidence intervals. Cohen's d effect size for depression was -0.541 (95% CI: -0.847 to -0.234, Z = -3.730, p<0.001), indicating that depression was significantly reduced in the reminiscence group compared to the control group. Increased quality of life and decreased BPSD were also found in the reminiscence group compared to the control group.

CONCLUSION

Reminiscence therapy has a moderate effect on depression and can be broadly used to decrease depression as an alternative to antipsychotics, which can have harmful side effects and high cost.

The Effect of Reminiscence Therapy With Internet-Based Videos on Cognitive Status and Apathy of Older People With Mild Dementia

This study was carried out to assess the effects of reminiscence therapy that was supported with internet-based videos on the cognitive condition and apathy levels of older people with mild dementia living in nursing homes. This randomized controlled experimental study was conducted between May 15, 2016, and August 25, 2016, in two nursing homes in Adana, Turkey. A total of 32 people participated in this study, 16 individuals were in the intervention group and 16 individuals were in the control group. The data were collected using a Personal Information Form, the Standardized Mini-Mental State Examination (SMMSE) test, and the Apathy Rating Scale (ARS) Self-assessment Form. The individuals in the intervention group received group reminiscence therapy involving internet-based videos for 60 minutes once a week for 3 months. During this period, 25 to 30 minutes of unstructured interviews were carried out with individuals in the control group. The data were analyzed using descriptive statistics, Student t test, the Mann-Whitney U test, and Wilcoxon signed rank test. In this study, a significant difference was found between experimental and control groups' posttest mean scores on the SMMSE test and ARS ( P < .01). The experimental group's SMMSE test and ARS posttest mean scores were higher than those of the control group ( P < .01). This study found that group reminiscence therapy using internet-based videos improved the cognitive functions and apathy levels of older people with mild dementia of the Alzheimer type. It is recommended that group reminiscence therapy studies with Internet-based videos be conducted in care institutions that are responsible for managing older people with mild dementia of the Alzheimer type.

Telling life stories: a dyadic intervention for older Korean couples affected by mild Alzheimer's disease

ABSTRACTBackground:Dementia has negative consequences for both persons with dementia and their family caregivers. Dyadic interventions in which both groups participate together have shown an effective and promising approach. The Couples Life Story Approach (CLSA) that was recently developed for older couples dealing with dementia in the USA was adapted and implemented for the older Korean population in this study. The purpose of this paper is to understand how older Korean couples dealing with dementia experienced the CLSA.

METHOD

Fifty six couples (n = 102) completed the five-week intervention from December 2013 to October 2015. The participants completed a survey including open-ended questions one week after finishing the intervention. A thematic content analysis was conducted to analyze the responses.

RESULTS

Qualitative analysis revealed benefits and challenges in the experience of CLSA. Themes related to benefits were: (1) emotional benefits of reminiscing; (2) positive evaluation of life as a couple; (3) gratitude toward spouse; (4) changes in communications or activities with spouse; and (5) changes in relationship quality. Couples' experience varied, with some having mixed feelings about the intervention. Challenges perceived by participants included revival of bitterness and identification of loss.

CONCLUSIONS

Findings suggest the CLSA contributes to enhancing the quality of life for couples affected by Alzheimer's disease and improving their relationship. Challenges that emerged in the CLSA will guide future research to identify the sub-population that is appropriate for the couple-oriented intervention in dementia care.

Reminiscence therapy for dementia

BACKGROUND

This updated Cochrane Review of reminiscence therapy (RT) for dementia was first published in 1998, and last updated in 2005. RT involves the discussion of memories and past experiences with other people using tangible prompts such as photographs or music to evoke memories and stimulate conversation. RT is implemented widely in a range of settings using a variety of formats.

OBJECTIVES

To assess the effects of RT on people living with dementia and their carers, taking into account differences in its implementation, including setting (care home, community) and modality (group, individual).

SEARCH METHODS

We searched ALOIS (the Cochrane Dementia and Cognitive Improvement Group's Specialized Register) on 6 April 2017 using the search term 'reminiscence.'

SELECTION CRITERIA

We included all randomised controlled trials of RT for dementia in which the duration of the intervention was at least four weeks (or six sessions) and that had a 'no treatment' or passive control group. Outcomes of interest were quality of life (QoL), cognition, communication, behaviour, mood and carer outcomes.

DATA COLLECTION AND ANALYSIS

Two authors (LOP and EF) independently extracted data and assessed risk of bias. Where necessary, we contacted study authors for additional information. We pooled data from all sufficiently similar studies reporting on each outcome. We undertook subgroup analysis by setting (community versus care home) and by modality (individual versus group). We used GRADE methods to assess the overall quality of evidence for each outcome.

MAIN RESULTS

We included 22 studies involving 1972 people with dementia. Meta-analyses included data from 16 studies (1749 participants). Apart from six studies with risk of selection bias, the overall risk of bias in the studies was low.Overall, moderate quality evidence indicated RT did not have an important effect on QoL immediately after the intervention period compared with no treatment (standardised mean difference (SMD) 0.11, 95% confidence interval (CI) -0.12 to 0.33; I² = 59%; 8 studies; 1060 participants). Inconsistency between studies mainly related to the study setting. There was probably a slight benefit in favour of RT in care homes post-treatment (SMD 0.46, 95% CI 0.18 to 0.75; 3 studies; 193 participants), but little or no difference in QoL in community settings (867 participants from five studies).For cognitive measures, there was high quality evidence for a very small benefit, of doubtful clinical importance, associated with reminiscence at the end of treatment (SMD 0.11, 95% CI 0.00 to 0.23; 14 studies; 1219 participants), but little or no difference at longer-term follow-up. There was a probable slight improvement for individual reminiscence and for care homes when analysed separately, but little or no difference for community settings or for group studies. Nine studies included the widely used Mini-Mental State Examination (MMSE) as a cognitive measure, and, on this scale, there was high quality evidence for an improvement at the end of treatment (mean difference (MD) 1.87 points, 95% CI 0.54 to 3.20; 437 participants). There was a similar effect at longer-term follow-up, but the quality of evidence for this analysis was low (1.8 points, 95% CI -0.06 to 3.65).For communication measures, there may have been a benefit of RT at the end of treatment (SMD -0.51 points, 95% CI -0.97 to -0.05; I² = 62%; negative scores indicated improvement; 6 studies; 249 participants), but there was inconsistency between studies, related to the RT modality. At follow-up, there was probably a slight benefit of RT (SMD -0.49 points, 95% CI -0.77 to -0.21; 4 studies; 204 participants). Effects were uncertain for individual RT, with very low quality evidence available. For reminiscence groups, evidence of moderate quality indicated a probable slight benefit immediately (SMD -0.39, 95% CI -0.71 to -0.06; 4 studies; 153 participants), and at later follow-up. Community participants probably benefited at end of treatment and follow-up. For care home participants, the results were inconsistent between studies and, while there may be an improvement at follow-up, at the end of treatment the evidence quality was very low and effects were uncertain.Other outcome domains examined for people with dementia included mood, functioning in daily activities, agitation/irritability and relationship quality. There were no clear effects in these domains. Individual reminiscence was probably associated with a slight benefit on depression scales, although its clinical importance was uncertain (SMD -0.41, 95% CI -0.76 to -0.06; 4 studies; 131 participants). We found no evidence of any harmful effects on people with dementia.We also looked at outcomes for carers, including stress, mood and quality of relationship with the person with dementia (from the carer's perspective). We found no evidence of effects on carers other than a potential adverse outcome related to carer anxiety at longer-term follow-up, based on two studies that had involved the carer jointly in reminiscence groups with people with dementia. The control group carers were probably slightly less anxious (MD 0.56 points, 95% CI -0.17 to 1.30; 464 participants), but this result is of uncertain clinical importance, and is also consistent with little or no effect.

AUTHORS' CONCLUSIONS

The effects of reminiscence interventions are inconsistent, often small in size and can differ considerably across settings and modalities. RT has some positive effects on people with dementia in the domains of QoL, cognition, communication and mood. Care home studies show the widest range of benefits, including QoL, cognition and communication (at follow-up). Individual RT is associated with probable benefits for cognition and mood. Group RT and a community setting are associated with probable improvements in communication. The wide range of RT interventions across studies makes comparisons and evaluation of relative benefits difficult. Treatment protocols are not described in sufficient detail in many publications. There have been welcome improvements in the quality of research on RT since the previous version of this review, although there still remains a need for more randomised controlled trials following clear, detailed treatment protocols, especially allowing the effects of simple and integrative RT to be compared.

A Novel and Intelligent Home Monitoring System for Care Support of Elders with Cognitive Impairment

BACKGROUND

Assistive technology, in the form of a smart home environment, is employed to support people with dementia.

OBJECTIVES

To propose a system for continuous and objective remote monitoring of problematic daily living activity areas and design personalized interventions based on system feedback and clinical observations for improving cognitive function and health-related quality of life.

METHODS

The assistive technology of the proposed system, including wearable, sleep, object motion, presence, and utility usage sensors, was methodically deployed at four different home installations of people with cognitive impairment. Detection of sleep patterns, physical activity, and activities of daily living, based on the collected sensor data and analytics, was available at all times through comprehensive data visualization solutions. Combined with clinical observation, targeted psychosocial interventions were introduced to enhance the participants' quality of life and improve their cognitive functions and daily functionality. Meanwhile, participants and their caregivers were able to visualize a reduced set of information tailored to their needs.

RESULTS

Overall, paired-sample t-test analysis of monitored qualities revealed improvement for all participants in neuropsychological assessment. Moreover, improvement was detected from the beginning to the end of the trial, in physical condition and in the domains of sleep. Detecting abnormalities via the system, for example in sleep quality, such as REM sleep, has proved to be critical to assess current status, drive interventions, and evaluate improvements in a reliable manner.

CONCLUSION

It has been proved that the proposed system is suitable to support clinicians to reliably drive and evaluate clinical interventions toward quality of life improvement of people with cognitive impairment.

Physical and mental health status and their correlations among older wheelchair users with dementia in long-term care facilities

PURPOSE

To investigate the physical health (daily functioning and functional fitness) and mental health (depression and behavioral dysfunction) of older wheelchair users with dementia in long-term care facilities, examine the correlations between physical and mental health, and identify the independent variables of their daily functioning.

METHODS

A descriptive correlational method was adopted, which was conducted in six long-term care facilities in three cities, south Taiwan. Participants comprised 98 older wheelchair users with dementia. Data were collected using structured questionnaires (Mini-Mental State Examination, Barthel Index, Cornell Scale for Depression in Dementia, and Clifton Assessment Procedures for the Elderly Behavior Rating Scale) and from functional fitness testing (cardiopulmonary functioning, body flexibility, joint mobility, and muscle strength and endurance).

RESULTS

Older adults with dementia who had high depression scores were likely to have more behavioral dysfunctions, poorer performance in shoulder flexion and abduction, and lower upper limb muscle strength and endurance. More behavioral dysfunctions were associated with poorer daily functioning, lung capacity, body flexibility, shoulder flexion, and upper limb muscle strength and endurance. Those with better lung capacity, body flexibility, upper limb muscle strength, and endurance were likely to have high daily functioning scores (all p < .05). The key independent variables associated with daily functioning were behavioral dysfunction, lower body flexibility, and lung capacity, which together explained 59.3% of the total variance.

CONCLUSIONS

Further research should develop appropriate activity-based intervention programs for older wheelchair users with dementia to delay their deterioration and promote their physical and mental health.

Effectiveness of Occupational Therapy Interventions to Enhance Occupational Performance for Adults With Alzheimer's Disease and Related Major Neurocognitive Disorders: A Systematic Review

OBJECTIVE

The purpose of this systematic review was to describe the evidence for the effectiveness of interventions designed to establish, modify, and maintain occupations for adults with Alzheimer's disease (AD) and related neurocognitive disorders.

METHOD

Titles and abstracts of 2,597 articles were reviewed, of which 256 were retrieved for full review and 52 met inclusion criteria. U.S. Preventive Services Task Force levels of certainty and grade definitions were used to describe the strength of evidence.

RESULTS

Articles were categorized into five themes: occupation-based, sleep, cognitive, physical exercise, and multicomponent interventions. Strong evidence supports the benefits of occupation-based interventions, physical exercise, and error-reduction learning.

CONCLUSION

Occupational therapy practitioners should integrate daily occupations, physical exercise, and error-reduction techniques into the daily routine of adults with AD to enhance occupational performance and delay functional decline. Future research should focus on establishing consensus on types and dosage of exercise and cognitive interventions.

AIM

The present study aimed to determine the impact of group integrative reminiscence therapy on mental health of older women living in Iranian nursing home in 2016.

DESIGN

A quasi-experimental design pre- and post-test was used in the present study. Purposive sampling was used to recruit participants who met the study criteria.

METHOD

The statistical population included 60 older women living in nursing home, among whom 46 having the inclusion criteria were selected as the sample. After completing the Goldberg's General Health Questionnaire, the older people were divided into intervention (N = 23) and control (N = 23) group by using block randomization method. The intervention groups were trained by integrative reminiscence therapy for 60-90 min 10 sessions, twice a week. Descriptive statistics and ANOVA were used for data analysis by SPSS software.

RESULTS

The results indicated that group integrative reminiscence therapy significantly affected general mental health and physical dimensions, anxiety and insomnia, social functions and depression.

Systematic review of systematic reviews of non-pharmacological interventions to treat behavioural disturbances in older patients with dementia. The SENATOR-OnTop series

OBJECTIVE

To provide an overview of non-pharmacological interventions for behavioural and psychological symptoms in dementia (BPSD).

DESIGN

Systematic overview of reviews.

DATA SOURCES

PubMed, EMBASE, Cochrane Database of Systematic Reviews, CINAHL and PsycINFO (2009-March 2015).

ELIGIBILITY CRITERIA

Systematic reviews (SRs) that included at least one comparative study evaluating any non-pharmacological intervention, to treat BPSD.

DATA EXTRACTION

Eligible studies were selected and data extracted independently by 2 reviewers.The AMSTAR checklist was used to assess the quality of the SRs.

DATA ANALYSIS

Extracted data were synthesised using a narrative approach.

RESULTS

38 SRs and 129 primary studies were identified, comprising the following categories of non-pharmacological interventions: (1) sensory stimulation interventions (25 SRs, 66 primary studies) that encompassed: shiatsu and acupressure, aromatherapy, massage/touch therapy, light therapy, sensory garden and horticultural activities, music/dance therapy, dance therapy, snoezelen multisensory stimulation therapy, transcutaneous electrical nerve stimulation; (2) cognitive/emotion-oriented interventions (13 SRs; 26 primary studies) that included cognitive stimulation, reminiscence therapy, validation therapy, simulated presence therapy; (3) behaviour management techniques (6 SRs; 22 primary studies); (4) Multicomponent interventions (3 SR; four primary studies); (5) other therapies (5 SRs, 15 primary studies) comprising exercise therapy, animal-assisted therapy, special care unit and dining room environment-based interventions.

CONCLUSIONS

A large number of non-pharmacological interventions for BPSD were identified. The majority of the studies had great variation in how the same type of intervention was defined and applied, the follow-up duration, the type of outcome measured, usually with modest sample size. Overall, music therapy and behavioural management techniques were effective for reducing BPSD.

Resistance Band Exercises Reduce Depression and Behavioral Problems of Wheelchair-Bound Older Adults with Dementia: A Cluster-Randomized Controlled Trial

OBJECTIVES

To test the effects of a 15-month wheelchair-bound resistance band exercise program on depression and behavioral problems of wheelchair-bound older adults with dementia.

DESIGN

Single-blind, cluster-randomized controlled trial with repeated measures.

SETTING

Eight nursing homes in southern Taiwan.

PARTICIPANTS

Wheelchair-bound nursing home older adults with dementia who participated voluntarily (N = 150) were cluster-randomized to two groups (experimental or control group); 127 completed the study (experimental: four nursing homes, n = 65; control: four nursing homes, n = 62).

INTERVENTION

The resistance band exercises were conducted three times per week in 40-minute sessions in the following two sequences: volunteer-led sessions for the first 6 months (Stage I) followed by DVD-guided sessions for the next 9 months (Stage II).

MEASUREMENTS

Depression, as measured using the Cornell Scale for Depression in Dementia, and behavioral problems, as measured using the Clifton Assessment Procedures for the Elderly-Behavior Rating Scale, of participants were observed at six time points at 3-month intervals: pretest, two posttests at Stage I, and three posttests at Stage II.

RESULTS

By the sixth month of the study, experimental group participants were significantly less depressed and had fewer behavioral problems than control group participants (all P < .05). These small but statistically significant differences persisted throughout the 9 months of the DVD-guided sessions (all P < .05).

CONCLUSION

Volunteer-led sessions followed by DVD-guided sessions of resistance band exercise is effective and practical in institutional settings.

A quasi-experimental study of a reminiscence program focused on autobiographical memory in institutionalized older adults with cognitive impairment

Working with past memories through reminiscence interventions has been practiced for several decades with successful outcomes on mental health in older adults. Few studies however have focused on autobiographical memory recall in older individuals with cognitive impairment. This study aims to analyze the impact of an individual reminiscence program in a group of older persons with cognitive decline living in nursing homes on the dimensions of cognition, autobiographical memory, mood, behavior and anxiety. A two-group pre-test and post-test design with single blinded assessment was conducted. Forty-one participants were randomized to an experimental group (n=20) and a control group (n=21). The first group attended five weekly individual reminiscence sessions. Changes in the outcome measures were examined for cognition (Montreal Cognitive Assessment; Autobiographical Memory Test), behavior (Alzheimer Disease Assessment Subscale Non-Cog) and emotional status (Cornell Scale for Depression in Dementia; Geriatric Depression Scale, and Geriatric Anxiety Inventory). Participants attending reminiscence sessions exhibited better outcomes compared to the control group in cognition, anxiety and depression (p<0.001), and presented a higher number of retrieved autobiographical events, specificity of evoked memories and positive valence of events (p<0.001), and also presented lower latency time for recalling events, and lower negative recalled events (p<0.01). This study supports the potential value of reminiscence therapy in improving the recall of autobiographical memory. Reminiscence therapy can be helpful to maintain or improve cognitive function, decrease anxiety and manage depressive symptoms and altered behavior, but further investigation is needed to clarify long-term effects.

Effectiveness of the Modified Instrumental Reminiscence Intervention on Psychological Well-Being Among Community-Dwelling Chinese Older Adults: A Randomized Controlled Trial

OBJECTIVE

The current study aimed to examine the effectiveness of the Instrumental Reminiscence Intervention-Hong Kong (IRI-HK) on alleviating depressive symptoms and improving life satisfaction in Chinese older adults living in empty nests (i.e., living alone or with a spouse only) in the community.

METHODS

A longitudinal, randomized, controlled design was adopted. Experimental and wait-list control groups were provided with the IRI-HK immediately and 12 weeks after the baseline assessment, respectively. Participants were 114 older adults living in empty nests and recruited via local elderly community centers. This high-risk population with detectable depressive symptoms were randomized into experimental (N = 46) and control (N = 68) groups. The IRI-HK is a group reminiscence intervention modified with cultural adaptations for Chinese older adults. It emphasizes the use of problem-focused coping strategies and comprises six intervention sessions and two follow-up sessions. Participants' depressive symptoms and life satisfaction were measured by the Chinese version of the Geriatric Depression Scale-Short Form and the Life Satisfaction Scale-Chinese, respectively.

RESULTS

Findings from this study showed a significant difference in depressive symptoms between groups after the intervention, F(1,77) = 35.62, p <0.001. Life satisfaction of the experimental group after the second follow-up was found to be significantly higher than that of the control group, F(1,68) = 5.67, p <0.05.

CONCLUSION

The IRI-HK was a successful cultural adaption suitable for use in the Chinese context. It was found to be an effective intervention for alleviating depressive symptoms in older adults living in empty nests in the community.

Baseball reminiscence league: a model for supporting persons with dementia

Reminiscence therapy for persons with dementia improves socialization and quality of life. Herein we report the development of reminiscence groups based around memories of professional baseball. Preliminary feedback suggests that this can be a successful approach to enhancing quality of life for persons with mild to moderate dementia.

A systematic review of the use of technology for reminiscence therapy

As the segment of the population 65 years of age or older continues to grow, the number of individuals with dementia increases proportionally, highlighting the need to design therapies that meet the social and emotional needs of people with dementia. Information and communication technologies (ICT) are potential venues for supporting the delivery of such therapies, including reminiscence therapy (RT), which is a non-pharmacological intervention involving the prompting of past memories, often with artifacts such as old photographs or music for therapeutic benefits such as the facilitation of social interactions or the increase of self-esteem. This paper systematically examines the scientific literature on the use of ICT for facilitating RT to assess the current state of the evidence and identify future trends. We searched the PubMed (1966-2013), ACM (1954-2013), and PsycINFO (1908-2013) repositories using the keywords dementia and reminiscence. Three hundred eighty-six articles were retrieved, 44 of which met the inclusion and exclusion criteria. Findings of the systematic review include that there are benefits to using ICT for RT interventions. Some of these benefits are access to rich and engaging multimedia reminiscence materials, opportunities for people with dementia to participate in social interactions and take ownership of conversations, and a reduction of barriers due to motor deficits during interactions with media. Future studies should explore the types and content of media beneficial to individuals at different stages of dementia.

The value of personalized psychosocial interventions to address behavioral and psychological symptoms in people with dementia living in care home settings: a systematic review

BACKGROUND

Several important systematic reviews and meta-analyses focusing on psychosocial interventions have been undertaken in the last decade. However, they have not focused specifically on the treatment of individual behavioral and psychological symptoms of dementia (BPSD) with personalized interventions. This updated systematic review will focus on studies reporting the effect of personalized psychosocial interventions on key BPSD in care homes.

METHODS

Systematic review of the evidence for psychosocial interventions for BPSD, focusing on papers published between 2000 and 2012. All care home and nursing home studies including individual and cluster randomized controlled trials (RCTs) and pre-/post-test studies with control conditions were included.

RESULTS

641 studies were identified, of which 40 fulfilled inclusion and exclusion criteria. There was good evidence to support the value of personalized pleasant activities with and without social interaction for the treatment of agitation, and reminiscence therapy to improve mood. The evidence for other therapies was more limited.

CONCLUSIONS

There is a growing body of evidence indicating specific effects of different personalized psychosocial interventions on individual BPSD and mood outcomes.

Effects of reminiscence interventions on psychosocial outcomes: a meta-analysis

OBJECTIVES

This study integrated results from controlled trials of reminiscence interventions.

METHODS

Meta-analysis was used to aggregate results from 128 studies on 9 outcome VARIABLES.

RESULTS

Compared to non-specific changes in control-group members, moderate improvements were observed at posttest with regard to ego-integrity (g=0.64) and depression (g=0.57 standard deviation units). Small effects were found on purpose in life (g=0.48), death preparation (g=0.40), mastery (g=0.40), mental health symptoms (g=0.33), positive well-being (g=0.33), social integration (g=0.31), and cognitive performance (g=0.24). Most effects were maintained at follow-up. We observed larger improvements of depressive symptoms in depressed individuals (g=1.09) and persons with chronic physical disease (g=0.94) than in other individuals, and in those receiving life-review therapy (g=1.28) rather than life-review or simple reminiscence. Moderating effects of the control condition were also detected.

CONCLUSIONS

Reminiscence interventions affect a broad range of outcomes, and therapeutic as well as preventive effects are similar to those observed in other frequently used interventions.

The prevalence of dementia and depression in Taiwanese institutionalized leprosy patients, and the effectiveness evaluation of reminiscence therapy--a longitudinal, single-blind, randomized control study

OBJECTIVE

This study investigated the prevalence of depression and dementia in long-term institutionalized older leprosy patients in Taiwan. We then examined the effectiveness of reminiscence group therapy on depressive symptoms and cognitive function in this population.

METHODS

We recruited 129 long-term institutionalized older leprosy patients in Taiwan and used the Geriatric Depression Scale-Short Form (GDS-SF), the mini mental state examination (MMSE), and the Clinical Dementia Rating (CDR) scale for outcome measurement. We then conducted a single-blind, randomized, longitudinal quasi-experimental analysis comparing the pre-test and post-test results of two equivalent groups at a 24-week intervention interval. The intervention in the experimental group was three sessions of reminiscence group therapy per week, whereas that in the control group was weekly individual supportive interviews.

RESULTS

The prevalence of dementia was 45.7-50.4% according to a CDR score ≥ 0.5 and an MMSE score < 25, and the prevalence of depression was 25% based on a GDS-SF score ≥ 7. According to the Wilcoxon signed-rank test, the GDS-SF scores in the experimental group decreased significantly (p = 0.02) after intervention as compared with that in the control group (p = 0.22), whereas the MMSE scores in both groups remained steady.

CONCLUSIONS

The prevalence of dementia and depression in long-term institutionalized older leprosy patients in Taiwan is high. Reminiscence group therapy has been confirmed effective on depression in this population, but its effectiveness on cognitive function requires further verification.

The clinical significance of cognition-focused interventions for cognitively impaired older adults: a systematic review of randomized controlled trials

BACKGROUND

Cognitive stimulation, training or rehabilitation can achieve modest, skill-specific gains in cognitively healthy older adults. With regard to the limited efficacy of currently available anti-dementia drugs it is crucial to investigate whether such treatments also provide clinically meaningful benefits to cognitively impaired older individuals.

METHODS

We conducted a systematic review of randomized controlled trials evaluating cognition-focused interventions in participants with mild cognitive impairment or dementia. Meta-analytic strategies were used to calculate effect sizes.

RESULTS

Cognition-focused interventions confer small and inconsistent effects on trained cognitive skills which, according to some studies, translate into gains on general cognitive ability. Instruments measuring such effects such as the Mini-Mental State Examination (MMSE) or the Alzheimer's Disease Assessment Scale, cognitive part (ADAS-Cog) show standardized mean differences of 0.20 and 0.30, respectively, which are comparable with those of current antidementia drug treatments. However, convincing evidence of clinical significance was only obtained from single trials in terms of delay of cognitive decline, improvement in activities of daily living, or enhanced attainment of personally relevant goals.

CONCLUSIONS

The potential of cognition-focused interventions has probably been obscured by the methodological inconsistencies and limitations of the clinical studies conducted thus far. Further randomized controlled trials on the efficacy of these treatment modalities are required using optimized and consistent methods. Emphasis should be placed on tailoring interventions to individual needs and resources while maintaining a high level of standardization, on implementing newly acquired skills and strategies in the everyday context, on appropriate treatment duration, and on including person-centered outcomes.

Impact of the life review program on elders with dementia: a preliminary study at a day care center in southern Taiwan

BACKGROUND

: Life review, a type of reminiscence therapy, assists participants to seek personal value in order to enhance social status and maintain a high quality of life (QOL).

PURPOSE

: This study aimed to examine the impact of an adaptive life review program (LRP) on perceived QOL in elders with mild to moderate dementia at a day care center and assess the effect, if any, of different cognitive impairment levels on intervention outcome.

METHODS

: This pre-experimental design used a single group of seven subjects for pretest and posttest and purposive sampling at a 2-week interval. Researchers administered to each subject a 10-day therapeutic recreation program modified from Tabourne's (1991) LRP.

RESULTS

: Posttest results found no statistically significant improvements. However, subjects reported higher mean scores of perceived QOL as measured by the 36-Item Short Form Health Survey. This finding indicated a trend of improving physical and mental health after the intervention. In addition, subjects with moderate cognitive impairment reported a higher improvement in physical health perception than did subjects with mild cognitive impairment.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

: Future research should include a larger sample size and a longer period of intervention and adopt multiple dimensions of QOL measurements to increase research rigor. Suggestions from this study can be used to improve the LRP.

Improved social interaction and increased anterior cingulate metabolism after group reminiscence with reality orientation approach for vascular dementia

A group reminiscence approach (GRA) with reality orientation (RO) is widely used as a psychosocial intervention for dementia. Since clinical effectiveness was reported for the intervention, interest has been directed toward areas of the neuronal network that might be being stimulated. We hypothesized that the frontal lobe associated with social interaction was being stimulated. To test this hypothesis, we studied 24 patients with vascular dementia. In addition to conventional care, a 1-h session of GRA with RO was provided once a week for 3 months in the GRA-RO arm (n=12). Only supportive care was provided in the control arm (n=12). Before and after the interventions, cognitive function, depressive state, and social activities were assessed. Since glucose metabolism is associated with brain function, cerebral glucose metabolism was measured by positron emission tomography (PET). Regarding behavioral improvement, 10 patients in the GRA-RO arm showed improvement compared with only two patients in the control arm, a significant difference. PET demonstrated that metabolism in the anterior cingulate was increased in the GRA-RO arm, whereas no significant changes were observed in the control arm. These results suggest that GRA-RO stimulates the anterior cingulate and has a positive effect on social interaction.
