An evaluation of community-based cognitive stimulation therapy: a pilot study with an Irish population of people with dementia

Exploring outcome measures with cognitive stimulation therapies and how these relate to the experiences of people with dementia: A narrative literature review

A narrative literature review was undertaken to consider the outcome measures used in research on cognitive stimulation therapy (CST), cognitive training (CT) and cognitive stimulation (CS) interventions. This review extends findings from previous reviews by including a broad range of study methodologies, both qualitative and quantitative, and explored whether participant experiences of taking part in the research are discussed. A database search identified 1261 articles matching the search criteria, with 29 included in this review. Studies tended to use the manualised CST model, with 11 other models identified. Randomised control trials were chosen as the most used method to explore impact. Across the studies, 65 different outcome measures were used with people with dementia, and only four studies used a qualitative approach. Little information is provided on the assessment process in terms of time taken, assessor, or of the experience of the person with dementia. There is heterogeneity of measures used, within and across domains, and number, and agreement or consistency of measures would provide greater comparability across CS studies. Gaps in reporting were noted on the detail of the assessment process and the experience of people with dementia taking part in this research.

Experiences of people with progressive memory disorders participating in non-pharmacological interventions: a qualitative systematic review

OBJECTIVE

This review identified, critically appraised, and synthesized the available evidence on the experiences of people with progressive memory disorders who are involved in non-pharmacological interventions.

INTRODUCTION

Non-pharmacological interventions are widely used to improve the quality of life and general well-being of people with progressive memory disorders. While an array of intervention effects has been studied, a systematic review of experiences is needed. First-hand knowledge and experience provides insight into noteworthy aspects of the use and timing of non-pharmacological interventions both in the community and institutionalized care.

INCLUSION CRITERIA

The review included studies of people of all ages with progressive memory disorders who described their experiences of non-pharmacological interventions.

METHODS

The search strategy used a three-step approach and sought to locate both published and unpublished studies. Key databases included MEDLINE (PubMed), CINAHL (EBSCO), Medic, Scopus (Elsevier), and PsycARTICLES (ProQuest). MedNar was used to search for unpublished studies. The databases were searched from the date of inception of the database to May 2020, and a mix of controlled vocabulary (ie, MeSH, CINAHL headings) and keywords were used to capture all existing qualitative studies related to the experiences of people of all ages with progressive memory disorders participating in non-pharmacological interventions. Only English, Swedish, and Finnish studies were included during the screening of the study titles and abstracts. The recommended JBI approach was used for study selection, critical appraisal, data extraction, and data synthesis.

RESULTS

Forty-six studies were included in the review. The study designs included qualitative descriptions (n = 31), mixed methods (n = 8), grounded theory (n = 5), and ethnography (n = 2). The total number of participants was 444. The overall quality of the studies was rated as low or very low on the ConQual score, with dependability rated as low or moderate and credibility as moderate. Altogether, 189 findings were aggregated into eight categories and three synthesized findings. The synthesized findings describing the experiences of people with progressive memory disorders participating in a non-pharmacological intervention were as follows: i) It strengthened the sense of personhood; ii) it lightened up my life; and iii) what I find meaningful is that it was meant for us.

CONCLUSIONS

People with progressive memory disorders welcome non-pharmacological interventions. It is noteworthy that, regardless of what the interventions entailed, the participants experienced strengthened self-esteem and positive alterations to their daily life. To achieve the desired benefits, intervention development should embody communication based on equality and respect for those who suffer from memory disorders. However, the level of evidence of the review findings was evaluated as low or very low, which needs to be considered when applying the results in clinical practice.

Cognitive stimulation therapy (CST) for dementia: a systematic review of qualitative research

INTRODUCTION

Cognitive Stimulation Therapy (CST) is a well-established intervention for people with dementia shown to improve cognition and quality of life. Past research includes development of a longer term 'maintenance CST' and an individual CST programme. Previous reviews of CST have focused on quantitative outcomes or excluded certain formats of CST. This review aimed to fill this gap by evaluating how the voices of facilitators, carers and people with dementia in qualitative studies of CST can contribute to our understanding of its implementation and how it is experienced.

METHODS

The current systematic review explored the experience and perspectives of people with dementia, facilitators and carers. Thematic Analysis was used to analyse this data, alongside guidance on synthesising qualitative findings.

RESULTS

A systematic literature search retrieved 10 relevant studies using qualitative methodology. Eighteen themes were generated, which were grouped into three categories: 'Acceptability and feasibility', 'Features of CST' and 'Key outcomes'.

CONCLUSIONS

To our knowledge, this is the only review to explore solely qualitative studies of CST. Findings provided insight into the shared features, outcomes and factors affecting implementation, and suggested theories for discrepancies between quantitative and qualitative findings in the literature. Some of the common themes were also in keeping with past reviews.

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

OBJECTIVES

Cognitive Stimulation Therapy (CST) is an evidence-based group intervention shown to improve cognition and quality of life in dementia and is widely implemented across the NHS. However, no attempt has been made to understand the possible advantages, and/or disadvantages, of delivering CST in a group format. The main aim of the present study was to explore experiences of group interactions in CST and longer-term maintenance CST (MCST) groups.

METHOD

A total of twenty-one semi-structured in-depth interviews were conducted across four separate groups delivered in London, the East Midlands, South West and South East of England; including two CST and two MCST groups. Group members with mild to moderate dementia and facilitators from these groups were interviewed. Thematic analysis was used to analyse the data using NVivo software.

RESULTS

The final analysis identified six themes: 'benefits and challenges of group expression', 'importance of companionship and getting to know others, 'togetherness and shared identity', 'group entertainment', 'group support' and 'cognitive stimulation through the group'. The inter-connecting relationship between these themes are synthesised and summarised.

CONCLUSION

Findings support the notion that therapeutic advantages inherent to the group format exist in group-based CST. New insights into the challenges related to a group format are also highlighted and discussed. Future research may benefit from exploring the relationship between the identified experiences of group interactions and clinical outcomes.

Describing and measuring the ‘switch-on’ effect in people with dementia who participate in cognitive stimulation therapy: A mixed methods study

Introduction

Cognitive stimulation therapy is an evidence-based group intervention for promoting cognition and quality of life in people with dementia. This New Zealand study aimed to describe and measure the ‘switch-on’ effect, a recently reported benefit involving enhanced participation.

Method

A convergent parallel mixed methods design was implemented. Interviews guided by qualitative descriptive methodology were conducted with four community-dwelling men with mild dementia and their wives, before, during and after cognitive stimulation therapy. Concomitantly, participants with dementia were scored on the Volitional Questionnaire following a single-subject A–B design. Qualitative and quantitative data were analysed using NVivo-assisted thematic analysis and descriptive statistics respectively and conjointly.

Findings

‘Switch-on’ was found to be multi-dimensional in nature, with increased engagement and expanded scope in Doing, Feeling, Relating, and Thinking and Reflecting. ‘Switch-on’ occurred with a noticeable onset within 3 weeks, which was sustained and consolidated towards completion of cognitive stimulation therapy in both group and home environments. Three men showed concurrent improvements on the achievement sub-scale of the Volitional Questionnaire. However, the measure did not effectively capture ‘switch-on’ due to its ceiling effect.

Conclusion

Findings about ‘switch-on’ suggest broader, under-researched benefits of cognitive stimulation therapy that merit further exploration from an occupational therapy perspective.
