Group-based cognitive stimulation therapy for dementia: a qualitative study on experiences of group interactions

Integrating lived experience to develop a tailored sleep intervention for people living with dementia and carepartners

ObjectivesSleep disturbances are highly prevalent and have adverse health consequences for both people living with dementia and their carepartners. Despite this, they are under-addressed caregiving settings. This study aimed to explore these sleep disturbances and co-design a multimodal sleep intervention for people living with dementia and their carepartners.MethodsWe conducted two focus groups and five semi-structured interviews (n = 4 people living with dementia, n = 6 carepartners). Active involvement of community advisors was sought throughout the design, development, and facilitation phases. Reflexive thematic analysis was used to explore sleep-related experiences and receive feedback to shape intervention development.FindingsPeople living with dementia reported disruptions to sleep and circadian rhythms, including sleep disturbances and confusion between day and night. Multiple sleep challenges were encountered by carepartners including insomnia, hypervigilance, and daytime impairment. The proposed sleep intervention was received positively, with significant insights emphasising the need for a multimodal toolkit approach, adaptation of the intervention across different dementia stages, and a focus on tailoring the program to carepartners.ConclusionSleep interventions for caregivers and care-recipients should target both sleep and daytime functioning to ensure holistic support. Participants were receptive towards time-friendly, online, multimodal sleep interventions that combine cognitive behaviour therapies, light therapy, mindfulness, and exercise elements.

The effect of cognitive stimulation therapy (CST) on apathy, loneliness, anxiety and activities of daily living in older people with Alzheimer's disease: randomized control study

OBJECTIVES

This study was conducted to determine the effect of Cognitive Stimulation Therapy (CST) on apathy, loneliness, anxiety, and activities of daily living of individuals with Alzheimer's disease.

METHOD

The study was conducted in a daily care center between January 2023 and January 2024 in a randomized control study. A total of 52 people, 26 intervention and 26 control groups, were enrolled in the study and formed the sample of the study. Demographic Information Form, Apathy Evaluation Scale (AES-C), Geriatric Anxiety Scale (GAS), UCLA Loneliness Scale Short Form (UCLA-SF), and Functional Impairment in Dementia Scale (DAD) were used in the study.

RESULTS

After the intervention, it was found that the intervention group's levels of apathy, loneliness and anxiety were significantly reduced compared to the control group. In the intra-group comparisons, it was found that there was a significant difference between the pre-test and post-test scores of the AES-C, UCLA-SF, GAS of the individuals in the intervention group after the application of CST, and between the pre-test and pre-test scores of the DAD (p < 0.05).

CONCLUSION

CST was found to be effective in reducing apathy, loneliness and anxiety levels and increasing daily living activities in older people with Alzheimer's disease.

The efficacy of cognitive stimulation, cognitive training, and cognitive rehabilitation for people living with dementia: a systematic review and meta-analysis

Cognition-oriented treatments (COTs) are a group of non-pharmacological treatments aimed at maintaining or improving cognitive functioning. Specific recommendations on the use of these interventions in people living with dementia (PLwD) are included in the Italian Guideline on the Diagnosis and Treatment of Dementia and Mild Cognitive Impairment, developed by the Italian National Institute of Health. This systematic review and meta-analysis, based on the GRADE methodology, is part of the guideline. Considered outcomes included the cognitive functions, quality of life, and functional abilities of PLwD, taking into account disease severity, modality and system of delivery, and form of the intervention. The effectiveness of these interventions on caregivers' outcomes was also assessed. Both group and individual cognitive stimulation were reported as effective in supporting cognitive functions in PLwD at any degree of severity. Individual cognitive training and group cognitive training were reported as effective in improving global cognitive functions in people with mild dementia. Cognitive rehabilitation appeared to be effective only in improving the functional abilities of people with mild dementia. Cognitive rehabilitation appeared to be the most effective in improving caregivers' outcomes, with results suggesting a reduction in care burden. The observed differences in the effectiveness of these interventions in people with different disease severity can be explained by the intrinsic characteristics of each intervention. Despite the large number of available studies, a high clinical, statistical, and methodological heterogeneity was observed. More methodologically rigorous studies are needed to clarify the effectiveness of each protocol and modality of intervention.

Does Cognitive Stimulation Therapy show similar efficacy in individuals with mild-to-moderate dementia from varying etiologies? An examination comparing its effectiveness in Alzheimer's disease and vascular dementia

OBJECTIVE

The effectiveness of the Cognitive Stimulation Therapy (CST) is well-documented. Nevertheless, the question of whether specific subgroups of individuals with dementia are more or less likely to benefit from this cognitive stimulation intervention remains unaddressed. Here, we directly compared the effectiveness of the Italian CST (CST-IT), delivered in a previous multicenter controlled clinical trial, across two distinct cohorts of individuals clinically diagnosed with Alzheimer's Disease (AD, N = 30) and vascular dementia (VaD, N = 27) in the mild-to-moderate stage.

METHOD

The impact of dementia subtype (AD vs VaD) on immediate (at intervention completion) benefits of CST-IT in general cognitive functioning, communicative abilities, mood, behavior and perceived quality of life was evaluated through linear mixed effects models. The frequency and severity of neuropsychiatric symptoms at baseline was inserted as a covariate due to the different behavioral profile in the two groups. Exploratory analyses also investigated the potential differential effect of dementia subtype on long-term benefits (three months after intervention).

RESULTS

The CST-IT determined comparable immediate, clinically significant improvements in general cognition and communicative abilities. Dementia subtype influenced short-term benefits in depressive symptoms (with a greater decrease in AD patients) and quality of life (no significant impact in AD, and a small improvement in VaD). Such effects depended on diagnosis-related differences in neuropsychiatric symptoms. At long-term, benefits persisted in general cognition (though depending on the outcome considered). Improvements in narratives were seen in VaD, whereas communicative abilities in AD returned to baseline. Post-intervention gains in depressive symptoms persisted in AD, but not in VaD, although benefits in quality of life remained stable in the latter.

CONCLUSIONS

Different mechanisms of neuropsychological change after CST-IT were hypothesized for the different forms of dementia, particularly with respect to crucial outcomes such as language, mood and quality of life, with implications toward the delivery of such psychosocial intervention in clinical contexts.

Preliminary feasibility study of a cognitive stimulation therapy programme for older adults with an intellectual disability

BACKGROUND

Despite the increased risk for people with an intellectual disability developing dementia, post-diagnostic psychosocial supports such as cognitive stimulation therapy (CST) are not routinely offered and there is limited research examining this intervention with people with intellectual disabilities. The aim of this study was to explore the feasibility of CST for older adults with intellectual disability to support active ageing.

METHODS

Five client participants attended a 14-session CST group and four staff attended a focus group. Reflexive thematic analysis was used to investigate the client and staff narratives.

RESULTS

Three key themes were generated: (1) Brain Health, (2) Connecting with others, and (3) Barriers and Enablers.

CONCLUSION

Findings indicated the suitability of CST as a way of supporting active ageing for older adults with intellectual disability. This study adds to the growing knowledge about service provision for older adults and their changing needs as they age and identifies clinical implications such as staff training to support intervention adherence.

Cognitive Stimulation with Music in Older Adults with Cognitive Impairment: A Scoping Review

BACKGROUND

The use of music in cognitive interventions represents a possibility with potential worthy of further investigation in the field of aging, both in terms of prevention from dementia, in the phase of mild cognitive impairment, and in the treatment of overt dementia.

OBJECTIVES

Currently, the types of music-based interventions proposed in the literature are characterized by wide heterogeneity, which is why it is necessary to clarify which interventions present more evidence of effectiveness in stimulating different cognitive domains.

METHOD

The study was conducted in accordance with PRISMA guidelines for scoping reviews. By searching two different databases, PubMed and the Web of Science, all studies evaluating the cognitive effects of music-based interventions on people at early stages of cognitive decline (MCI or mild-to-moderate dementia) were selected.

RESULTS

The study selection included a total of 28 studies involving n = 1612 participants (mean age ranged from 69.45 to 85.3 years old). Most of the studies analyzed agree with the observation of an improvement, or at least maintenance, of global cognitive conditions (mainly represented by the results of the MMSE test) following music-based interventions, together with a series of other positive effects on verbal fluency, memory, and executive processes.

CONCLUSIONS

The results of this review suggest the introduction of music-based interventions as complementary approaches to usual cognitive treatments. Also, the use of standardized and well-defined protocols, in addition to strong methodological research approaches, is suggested. Music-based interventions are recommended in the early stages of dementia, in MCI, and in a preventive sense in healthy older adults.

Virtual Group Cognitive Stimulation Therapy for Dementia: Mixed-Methods Feasibility Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

Cognitive stimulation therapy (CST) is an evidence-based group intervention for people with dementia, with benefits for cognition and quality of life when delivered face-to-face. Many people are unable to attend face-to-face groups for reasons including health and transport issues. This study aimed to assess the feasibility and acceptability of online or "virtual" CST (vCST).

RESEARCH DESIGN AND METHODS

Single-blind, randomized controlled feasibility design with qualitative interviews. Forty-six people with mild-to-moderate dementia were randomly allocated to attend either 14 sessions of twice-weekly vCST (n = 24) or treatment as usual (TAU, defined as usual care; n = 22) over 7 weeks. Cognition, quality of life, and depression were assessed pre- and posttreatment. Qualitative interviews (n = 16) with participants and carers were analyzed using thematic analysis.

RESULTS

High levels of attendance, adherence, fidelity to the manual, and completion of outcomes were recorded. Recruitment appeared feasible although randomization may not have been acceptable to some. There were no statistical differences noted between vCST and TAU in any of the outcomes evaluated, although both quantitative and qualitative data indicated acceptability, with qualitative reports of improved outcomes including cognition.

DISCUSSION AND IMPLICATIONS

vCST appeared feasible to deliver but did not result in any changes in outcomes, as expected from an underpowered feasibility trial. CST is the main psychosocial intervention delivered for dementia in UK memory services and globally, with many services moving towards virtual CST delivery. Therefore, a fully powered RCT of the effectiveness of vCST is feasible and justified.

Online Cognitive Stimulation Therapy for Dementia in Brazil and India: Acceptability, Feasibility, and Lessons for Implementation

BACKGROUND

Cognitive stimulation therapy (CST) is an evidence-based, group psychosocial intervention for people with dementia, and it has a positive impact on cognition and quality of life. CST has been culturally adapted for use globally. It was developed as a face-to-face intervention but has recently been adapted for online delivery.

OBJECTIVE

In this study, we aimed to explore the feasibility and acceptability of online or virtual CST (vCST) delivery in India and Brazil, emphasizing barriers and facilitators to implementation.

METHODS

A single-group, multisite, mixed methods, feasibility study was conducted, with nested qualitative interviews. Primary feasibility outcomes were recruitment rate, attendance, attrition, acceptability, and outcome measure completion. Exploratory pre- and postintervention measures, including cognition and quality of life, were assessed. Qualitative interviews were conducted with people with dementia, family caregivers, and group and organizational leaders following intervention delivery, and the data were analyzed using the Consolidated Framework for Implementation Research.

RESULTS

A total of 17 vCST group sessions with 59 participants were conducted for 7 weeks, with 53% (31/59) of participants attending all 14 sessions. Attrition rate was 7% (4/59), and outcome measure completion rate at follow-up was 68% (40/59). Interviews took place with 36 stakeholders. vCST was acceptable to participants and group leaders and enabled vital access to services during pandemic restrictions. While online services broadened geographic access, challenges emerged concerning inadequate computer literacy, poor technology access, and establishing interpersonal connections online. Exploratory, uncontrolled analyses indicated positive trends in quality of life but negative trends in cognition and activities of daily living, but these results were not statistically significant.

CONCLUSIONS

vCST demonstrated feasibility and acceptability, serving as a crucial resource during the pandemic but raised challenges related to technology access, computer literacy, and long-term implementation. The study highlights the potential of vCST while emphasizing ongoing development and solutions to address implementation challenges.

Group cognitive stimulation therapy versus usual care for people with intellectual disabilities and dementia (CST-IDD) in the UK: protocol for a mixed-methods feasibility randomised controlled trial

INTRODUCTION

The prevalence of dementia is almost five times higher in people with intellectual disabilities compared with the general population. However, evidence-based treatments for this population are lacking, as most randomised controlled trials for dementia interventions have not included people with intellectual disabilities. Cognitive stimulation therapy (CST) has a robust evidence base in the general dementia population, consistently showing benefits to cognition, quality of life and being cost-effective. We are conducting a mixed-methods feasibility trial of group CST for people with intellectual disabilities and dementia, to determine if a future definitive randomised controlled trial is feasible.

METHODS AND ANALYSIS

Fifty individuals with intellectual disabilities and dementia will be randomised to either the intervention arm (14 sessions of group CST plus treatment as usual) or the control arm (treatment as usual). Randomisation will occur after informed consent has been obtained and baseline assessments completed. Each arm will have 25 participants, with the intervention arm divided into five or more CST groups with three to five participants in each. The outcomes will be feasibility of recruitment, acceptability and adherence of the intervention, suitability of study outcome measures and feasibility of collecting resource use data. Quantitative and qualitative approaches, including semistructured interviews with group participants, carers and group facilitators, will be employed to assess these outcomes.

ETHICS AND DISSEMINATION

This study has been approved by Essex REC (Ref: 21/EE/027) and the HRA ethical approval process through the Integrated Research Application System (IRAS ID: 306 756). We plan to publish the results in peer-reviewed journals and conferences as well as provide feedback to funders, sponsors and study participants.

Regulating the disenfranchised: Reciprocity & resistance under the Mental Capacity Act

This paper interrogates the legitimacy of formal ethical regulation regarding people with dementia under the Mental Capacity Act, 2005 in England and Wales. Under the Act, research among people diagnosed with dementia must be approved by Health Research Authority committees, irrespective of whether that research engages with health organisations or service users. As examples, I discuss two ethnographic dementia studies that do not engage with healthcare services, but which nonetheless require HRA approval. These instances raise questions regarding legitimacy and reciprocity in the governance of dementia. Through capacity legislation, the state exerts control over people with dementia, automatically delineating them as healthcare subjects because of their diagnoses. This diagnosis functions as a form of administrative medicalisation, rendering dementia a medical entity and those diagnosed with it the property of formal healthcare. However, many people with dementia in England and Wales do not receive related health or care services beyond diagnosis. This institutional imbalance of high governance and low support undermines the contractual citizenship of people with dementia, wherein state-citizen rights and responsibilities should be reciprocal. In response, I consider resistance to this system in ethnographic research. "Resistance" here is not necessarily deliberate, hostile, difficult or perceived, but rather encompasses micropolitical effects that are contrary to power or control, sometimes emerging from systems themselves rather than individual resistive actors. Resistance can be unintentional, through mundane failures to satisfy specific aspects of governance bureaucracies. It can also be deliberate, through refusals to comply with restrictions that seem cumbersome, inapplicable or unethical, potentially raising questions of malpractice and misconduct. I suggest that resistance is made more probable due to the expansion of governance bureaucracies. On the one hand, the potential for both unintentional and intentional transgression increases, while on the other hand, the capacity for those transgressions to be discovered and rectified decreases, because the maintenance of control over such a system requires vast resources. Behind this ethico-bureaucratic tumult, people with dementia themselves are largely invisible. People with dementia often have no interaction with committees that determine their research participation. This further renders ethical governance a particularly disenfranchising facet of the dementia research economy. The state stipulates that people with dementia must be treated differently because of their diagnoses, without consulting those people. In response, resistance to unethical governance could be intuitively deemed ethical per se, but I suggest that such a simplistic binary is somewhat misleading.

Carers' experience of everyday life impacted by people with dementia who attended a cognitive stimulation therapy (CST) group intervention: a qualitative systematic review

ObjectivesTo explore carers' experiences of everyday life impacted by people with dementia who attended a seven-week cognitive stimulation therapy (CST) group intervention.MethodsA systematic review of qualitative studies and qualitative mixed method studies was conducted. Eight databases were searched. The selected studies were screened and assessed for methodological quality using the Rayyan Qatar Computing Research Institute (QCRI) and Critical Appraisal Skills Programme Qualitative Checklist (CASP-QC). Three studies were included following an inductive content analysis.ResultsTwo themes were identified: 'Enrichment by enhanced communication' and 'Growth through positive emotional interaction'.ConclusionQualitative research on the impact of the CST group intervention on carers' everyday life with a person with dementia is scarce. Carers experienced feelings of enrichment due to improvement and equality in communication and a possible source of happiness. There was a sense of togetherness and reconnection through music and singing together as well as a sense of mutual growth, increased positive interaction, increased ability to socialize, and feelings of fondness when experiencing glimpses of the previous personality of the person with dementia. Nevertheless, knowledge about the impact of the CST group intervention on carers' personal everyday life is lacking and requires further research.

Cognitive stimulation to improve cognitive functioning in people with dementia

BACKGROUND

Cognitive stimulation (CS) is an intervention for people with dementia offering a range of enjoyable activities providing general stimulation for thinking, concentration and memory, usually in a social setting, such as a small group. CS is distinguished from other approaches such as cognitive training and cognitive rehabilitation by its broad focus and social elements, aiming to improve domains such as quality of life (QoL) and mood as well as cognitive function. Recommended in various guidelines and widely implemented internationally, questions remain regarding different modes of delivery and the clinical significance of any benefits. A systematic review of CS is important to clarify its effectiveness and place practice recommendations on a sound evidence base. This review was last updated in 2012.

OBJECTIVES

To evaluate the evidence for the effectiveness of CS for people with dementia, including any negative effects, on cognition and other relevant outcomes, accounting where possible for differences in its implementation.

SEARCH METHODS

We identified trials from a search of the Cochrane Dementia and Cognitive Improvement Group Specialized Register, last searched on 3 March 2022. We used the search terms: cognitive stimulation, reality orientation, memory therapy, memory groups, memory support, memory stimulation, global stimulation, cognitive psychostimulation. We performed supplementary searches in a number of major healthcare databases and trial registers to ensure the search was up-to-date and comprehensive.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) of CS for dementia published in peer review journals in the English language incorporating a measure of cognitive change.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. As CS is a psychosocial intervention, we did not expect those receiving or delivering CS to be blinded to the nature of the intervention. Where necessary, we contacted study authors requesting data not provided in the papers. Where appropriate, we undertook subgroup analysis by modality (individual versus group), number of sessions and frequency, setting (community versus care home), type of control condition and dementia severity. We used GRADE methods to assess the overall quality of evidence for each outcome.

MAIN RESULTS

We included 37 RCTs (with 2766 participants), 26 published since the previous update. Most evaluated CS groups; eight examined individual CS. Participants' median age was 79.7 years. Sixteen studies included participants resident in care homes or hospitals. Study quality showed indications of improvement since the previous review, with few areas of high risk of bias. Assessors were clearly blinded to treatment allocation in most studies (81%) and most studies (81%) reported use of a treatment manual by those delivering the intervention. However, in a substantial number of studies (59%), we could not find details on all aspects of the randomisation procedures, leading us to rate the risk of selection bias as unclear. We entered data in the meta-analyses from 36 studies (2704 participants; CS: 1432, controls: 1272). The primary analysis was on changes evident immediately following the treatment period (median length 10 weeks; range 4 to 52 weeks). Only eight studies provided data allowing evaluation of whether effects were subsequently maintained (four at 6- to 12-week follow-up; four at 8- to 12-month follow-up). No negative effects were reported. Overall, we found moderate-quality evidence for a small benefit in cognition associated with CS (standardised mean difference (SMD) 0.40, 95% CI 0.25 to 0.55). In the 25 studies, with 1893 participants, reporting the widely used MMSE (Mini-Mental State Examination) test for cognitive function in dementia, there was moderate-quality evidence of a clinically important difference of 1.99 points between CS and controls (95% CI: 1.24, 2.74). In secondary analyses, with smaller total sample sizes, again examining the difference between CS and controls on changes immediately following the intervention period, we found moderate-quality evidence of a slight improvement in self-reported QoL (18 studies, 1584 participants; SMD: 0.25 [95% CI: 0.07, 0.42]) as well as in QoL ratings made by proxies (staff or caregivers). We found high-quality evidence for clinically relevant improvements in staff/interviewer ratings of communication and social interaction (5 studies, 702 participants; SMD: 0.53 [95% CI: 0.36, 0.70]) and for slight benefits in instrumental Activities of Daily Living, self-reported depressed mood, staff/interviewer-rated anxiety and general behaviour rating scales. We found moderate-quality evidence for slight improvements in behaviour that challenges and in basic Activities of Daily Living and low-quality evidence for a slight improvement in staff/interviewer-rated depressed mood. A few studies reported a range of outcomes for family caregivers. We found moderate-quality evidence that overall CS made little or no difference to caregivers' mood or anxiety. We found a high level of inconsistency between studies in relation to both cognitive outcomes and QoL. In exploratory subgroup analyses, we did not identify an effect of modality (group versus individual) or, for group studies, of setting (community versus care home), total number of group sessions or type of control condition (treatment-as-usual versus active controls). However, we did find improvements in cognition were larger where group sessions were more frequent (twice weekly or more versus once weekly) and where average severity of dementia among participants at the start of the intervention was 'mild' rather than 'moderate'. Imbalance in numbers of studies and participants between subgroups and residual inconsistency requires these exploratory findings to be interpreted cautiously.

AUTHORS' CONCLUSIONS

In this updated review, now with a much more extensive evidence base, we have again identified small, short-term cognitive benefits for people with mild to moderate dementia participating in CS programmes. From a smaller number of studies, we have also found clinically relevant improvements in communication and social interaction and slight benefits in a range of outcomes including QoL, mood and behaviour that challenges. There are relatively few studies of individual CS, and further research is needed to delineate the effectiveness of different delivery methods (including digital and remote, individual and group) and of multi-component programmes. We have identified that the frequency of group sessions and level of dementia severity may influence the outcomes of CS, and these aspects should be studied further. There remains an evidence gap in relation to the potential benefits of longer-term CS programmes and their clinical significance.

Cognitive stimulation and cognitive results in older adults: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

The lack of cognitive activity accelerates age cognitive decline. Cognitive stimulation (CS) tries to enhance cognitive functioning. The purpose of this systematic review and meta-analysis was to evaluate the effects of CS on cognitive outcomes (general cognitive functioning and specific cognitive domains) in older adults (aged 65 years or older, cognitively healthy participants, or with mild cognitive impairment, or dementia).

METHODS

PubMed, Scopus and Web of Science databases were examined from inception to October 2021. A total of 1,997 studies were identified in these databases, and. 33 studies were finally included in the systematic review and the meta-analysis. Raw means and standard deviations were used for continuous outcomes. Publication bias was examined by Egger's Regression Test for Funnel Plot Asymmetry and the quality assessment tools from the National Institutes of Health.

RESULTS

CS significantly improves general cognitive functioning (mean difference=MD = 1.536, 95%CI, 0.832 to 2.240), memory (MD = 0.365, 95%CI, 0.300 to 0.430), orientation (MD = 0.428, 95%CI, 0.306 to 0.550), praxis (MD = 0.278, 95%CI, 0.094 to 0.462) and calculation (MD = 0.228, 95%CI, 0.112 to 0.343).

CONCLUSION

CS seems to increase general cognitive functioning, memory, orientation, praxis, and calculation in older adults.

Cultural Adaptation of Cognitive Stimulation Therapy (CST) for Portuguese People with Dementia

OBJECTIVES

Portugal is one of the most aged countries in the world and dementia is increasing among the Portuguese population. It is estimated to affect around 200,000 people in Portugal. There is a clear need for non-pharmacological interventions to ameliorate the symptoms of dementia and improve the quality of life. Cognitive Stimulation Therapy (CST), a worldwide well-known program developed in the United Kingdom (UK), is recognized as a cost-effective intervention, with benefits both in cognitive function and quality of life of people with mild to moderate dementia. We tested the feasibility and cultural appropriateness and adapted CST to Portuguese people with dementia.

METHODS

The Formative Method for Adapting Psychotherapy (FMAP) model for cultural adaptation was used. A focus group discussion with health professionals and caregivers provided the basis for cultural adaptation, as well as feedback from participants, caregivers, and facilitators after a pilot study.

RESULTS

Some modifications were required, especially related to linguistic issues, in 11 of the 14 CST sessions. The adapted program was found to be acceptable and enjoyable in a small sample of people with dementia in a rehabilitation context.

CONCLUSIONS

CST seems feasible and culturally appropriate in Portugal. A systematically developed and culturally adapted manual is ready to be used in a large-scale implementation and validation of CST in Portugal.

CLINICAL IMPLICATIONS

CST is a valid program for the Portuguese culture, contributes to the availability of a structured and effective clinical intervention for PwD in Portugal and to the possibility of comparing programs across countries.

Group experiences of cognitive stimulation therapy (CST) in Tanzania: a qualitative study

BACKGROUND

Tanzania is a low-income country in which medication for dementia is largely unavailable. Cognitive Stimulation Therapy (CST) is a group-based psychological treatment for people with dementia (PwD), shown to improve cognition and quality of life (QoL). It has previously been culturally adapted and piloted in Tanzania, shown to produce similar outcomes. UK research into CST suggests processes inherent to the group nature are key to its success. This study sought to identify group processes within CST in Tanzania and understand their impact on CST principles and outcomes.

METHODS

Data collection took place in rural Hai District, through qualitative semi-structured interviews. Sixteen PwD and four facilitators were recruited through convenience sampling and interviewed about their experiences of CST. Interviews were audio-recorded, translated, transcribed and analysed by thematic analysis.

RESULTS

Two main themes emerged: 'Positive group experiences' and 'Negative group experiences'. From this, a number of group processes were identified, such as helping behaviours and feeling understood by the group. Positive processes supported CST principles and participant improvement. Facilitators were influential over group dynamics. The group processes identified impacted CST principles and treatment outcomes.

CONCLUSIONS

This is the first study on group mechanisms of CST in Tanzania. It provides deeper insight into participants' experiences of CST, thus identifying specific processes underlying the quantitatively measured positive outcomes of CST in Tanzania by previous studies. It also reveals further cultural barriers to implementation, enabling amendments for optimization of treatment efficacy.

Unethical governance: capacity legislation and the exclusion of people diagnosed with dementias from research

This paper considers the potential for the Mental Capacity Act (MCA) of England and Wales to incentivise the exclusion of people with dementia from research. The MCA is intended to standardise and safeguard the inclusion of people with cognitive impairments in research. This entails various procedural requirements, which in pressurised research contexts can lead researchers to exclude people with dementia as a means of simplifying bureaucratic constraints. I consider the risks of an ‘unethical ethics’, wherein procedural ethics indirectly causes the exclusion of people with dementia from research, undermining historic successes toward increased inclusivity. I suggest several solutions, including enhanced sensitivity to impairments and shifting the burden of proof from justifying inclusion to justifying exclusion. The paper responds to the ‘ethics creep’ tradition in procedural ethics, and critical appraisals of capacity legislation in dementia research. This approach recognises that institutional research ethics is itself a major ethical concern and can unwittingly beget unethical practices. Dementia researchers must be alert to such unethical ethics.
