The concept of disability and its causal mechanisms in older people over time from a theoretical perspective: a literature review

Considerations when asking about "disability" in disability inclusive research

PURPOSE

There are several ways to include "disability" in research studies, which can be confusing or overwhelming for researchers, community members, and students. The aim of this paper is to share conceptualizations of disability and how to ask about "disability" in research studies. The paper provides a general introduction and brief analysis of the methodological approaches which can be used.

METHODS

We used reviews of the literature and extensive discussions to identify key articles, books, websites, and reports that provide guidance and examples of asking about disability in research.

RESULTS

Four primary approaches to asking study participants about disability were identified. For each of these, we provide background information, key points about the ways to use the approach including tools that have been developed, and example studies. A comparison table provides a high-level overview of similarities and differences in approaches. Other approaches and tools were also identified and are briefly described.

CONCLUSION

Researchers involved in disability and rehabilitation research should be aware that there is not one best or singular way to ask about disability when conducting research. The approach or approaches chosen for a particular study need to match the purpose of the study. It is important that researchers take time to carefully consider their options and choose the best fit for their study.

Stakeholder perspectives on the preferred service ecosystem for senior citizens living at home: a qualitative interview study

BACKGROUND

Most senior citizens want to live independently at home as long as possible. The World Health Organization recommends an age-friendly community approach by transforming the service ecosystem for senior citizens and basing it on the question "What matters to you?". However, there is limited research-based knowledge to determine the characteristics of the preferred service ecosystem from the perspectives of multiple stakeholders. Therefore, the aim of the study was to gain a deeper understanding of multiple stakeholder perspectives on the preferred service ecosystem for senior citizens living at home.

METHODS

Four stakeholder groups (n = 57) from a Norwegian municipality participated in an interview study in 2019 and 2020: senior citizens, carers, healthcare professionals, and managers. Data were analysed according to qualitative content analysis.

RESULTS

Overall, there was considerable correspondence between the four stakeholder groups' perspectives on the preferred service ecosystem for senior citizens. Six themes were developed: (1) "self-reliance - living independently at home as long as possible"; (2) "remaining active and social within the community"; (3) "support for living at home as long as possible"; (4) "accessible information and services"; (5) "continuity of services"; and (6) "compassionate and competent healthcare professionals".

CONCLUSIONS

In order to adapt and meet changing needs, the preferred service ecosystem should support senior citizens' autonomy through interpersonal relationships and involvement. Healthcare managers and decision makers should consider a broader range of practical and social support services. Municipalities should plan for and develop age-friendly infrastructures, while healthcare professionals should rely on their compassion and competence to meet senior citizens' needs.

Relationship between person, environmental factors, and activities of daily living performance among physically disabled older adults living at home: a structural equation model

BACKGROUND

Older adults with physical disability need long-term services and support, which incur enormous costs. However, supportive environments may reduce disability and promote aging in place. It is unclear how the physical and social environment affect different types of functional impairments and influence the performance of activities of daily living (ADL) in physically disabled older adults.

OBJECTIVE

The purpose of this study was to examine the relationship between person, environmental factors, and ADL performance among physically disabled older adults living at home.

METHODS

This was a cross-sectional study. Using long-term care insurance claims data from a pilot city in China, we used a structural equation model to assess the potential paths among person, environmental factors, and ADL performance.

RESULTS

Education and income had different influences on the social environment and physical environment. The functional impairments had significant effects on ADL performance, either directly or through physical environment (with handrails) and social environment (family support).

CONCLUSIONS

The present findings offer crucial evidence for understanding the interactions between a person and the environment, as well as their influence on physical ADLs, suggesting the importance of a supportive environment and a subpopulation-targeting strategy for disabled older adults.

Functional Capacity and Difficulties in Activities of Daily Living From a Cross-National Perspective

Objectives: This study investigated whether physical and cognitive functioning predicts developing difficulties in basic or instrumental activities of daily living (ADL/IADL), and whether country-level factors moderated the associations. Methods: 69,227 adults aged 50+ from 19 countries were followed for up to 14 years. Cox regression and meta-regression analyses were used. Results: Higher grip strength was associated with a 45% lower risk of developing ADL limitations and a 47% lower risk of IADL limitations. The corresponding values were 22% and 23% for peak flow, 20% and 23% for word recall, and 20% and 24% for temporal orientation. The associations were similar and statistically significant in most countries, but some associations were weaker in countries with lower GDP and lower service coverage. Discussion: Good physical and cognitive functional capacity protects from ADL and IADL limitations consistently across Western countries. The associations may be stronger in countries with more resources.
