Introduction Non‐pharmacological treatments (NPTs) have the potential to improve meaningful outcomes for older people at risk of, or living with dementia, but research often lacks methodological rigor and continues to produce mixed results. Methods In the current position paper, experts in NPT research have specified treatment targets, aims, and ingredients using an umbrella framework, the Rehabilitation Treatment Specification System. Results Experts provided a snapshot and an authoritative summary of the evidence for different NPTs based on the best synthesis efforts, identified main gaps in knowledge and relevant barriers, and provided directions for future research. Experts in trial methodology provide best practice principles and recommendations for those working in this area, underscoring the importance of prespecified protocols. Discussion We conclude that the evidence strongly supports various NPTs in relation to their primary targets, and discuss opportunities and challenges associated with a unifying theoretical framework to guide future efforts in this area.

Purpose. This paper reports findings from a project that sought to develop accessible guidelines for including people with dementia in qualitative interviews in a music therapy study, based on experience from people previously involved in qualitative music therapy research. Method. People with previous experience of qualitative music therapy research were invited to participate in semi-structured interviews about how the interview process could be made more accessible. Participants included four family-caregivers and three music therapy-researchers. Interview data were analysed using thematic analysis. Findings were used to develop guidelines for a subsequent study; reflections on the implementation of these guidelines are provided. Results. Five themes were identified: (a) motivators and barriers to participating in interviews; (b) pragmatic elements that impact interview participation; (c) relationship dynamics may impact the interview; (d) familiarity fosters comfort, enables preparation and support and (e) broader considerations for accessible research design. Conclusions. Themes identified align with reports from the extant literature. Reflections on implementation of the guidelines reveal the need for more clarity around the ethics of building rapport in qualitative research. Implications about future uses of the guidelines, including the use of music as a research tool are discussed.

Background: Recent research on the efficacy of music-based interventions for people with dementia have focused on specific outcomes and methods, and singing has been noted as a particularly beneficial activity. However, due to heterogeneity of research methods, there is a need to synthesise the findings of both quantitative and qualitative research in order to better understand both the impact and potential mechanisms of singing for people in this population.Method: This systematic review included quantitative, qualitative and mixed-methods studies, and analysed these using a systematic mixed-studies synthesis (with a results-based convergent approach). Quantitative and qualitative data were initially synthesised using a narrative synthesis and thematic synthesis method, respectively, before a final meta-integration method was used to synthesise common themes across the two data forms.Results: Electronic and hand search strategies revealed 1,815 relevant studies, 40 of which met the full eligibility criteria. Narrative synthesis of quantitative data revealed six key outcome areas (quality of life; psychological well-being; cognition; engagement; activities of daily living; care-partner well-being), and thematic synthesis of qualitative data generated seven themes relating to the impact and mechanisms of singing (pragmatic elements; social benefits; mood; identity; memory; flow-on effects; and relationships). Meta-integration identified four key areas relating to the impact and mechanisms of singing for people with dementia and care-partners: psychological well-being, quality of life, cognition, and care-partner well-being.Conclusion: Results from the syntheses suggest that singing can positively impact the lives of people with dementia and their care-partners, although due to heterogeneity of study design and outcome measures, it is difficult to draw conclusions based on quantitative data alone. Qualitative data provides further context and insights from participant perspectives, and when integrated with quantitative data, contextual factors that may influence the benefits that participants experience from singing are revealed.
