The MOSAIC study - psychological capacity in older people

Researchers from Charles Sturt University, Flinders University and the University of Adelaide, in collaboration with the World Health Organisation (WHO), will embark on a momentous multi-centre, international project to develop a scale to measure psychological capacity in older adults.

The project 'From deficit to capacity in healthy ageing: Development and validation of a measure of psychological capacity in older people' (known as 'The MOSAIC study') has been awarded a 2.5-year grant of $1.22 million by Velux Stiftung, Switzerland.

Impact summary

This pioneering research will contribute to global monitoring systems for healthy ageing by delivering the world’s first single comprehensive  measure of psychological capacity in later life that is fit for purpose and appropriate for a wider global community.

The project will empower governments, health systems, and aged care services to better support older adults by focusing on their capabilities rather than deficits.

Research problem

As populations age worldwide, the challenge is not just longer life but ensuring those years are healthy and fulfilling.

In 2015, the WHO introduced a framework for healthy ageing built on intrinsic capacity—the combination of mental and physical abilities. However, one of its key components, psychological capacity, remains poorly defined and unmeasured. This gap limits the effectiveness of policy, care planning, and services that aim to promote healthy ageing.

Funding

• International Partner: World Health Organization (WHO).
• Funder: Velux Stiftung, Switzerland ($1.22 million grant over 2.5 years).

Outcomes

• Development of a culturally valid and psychometrically sound measurement scale for psychological capacity.
• Establishment of a capacity-based definition of psychological capacity.
• Generation of baseline data to inform policy, practice, and further research.
• Academic publications and practical tools for global health and aged care systems.

Impact

his study will lay the groundwork for future global policies and interventions that prioritise well-being, independence, and inclusion for older adults. By focusing on capabilities, the project challenges traditional deficit-based models of ageing and supports the transformation of aged care towards empowerment and dignity.

Beneficiaries

• Older adults across diverse global contexts.
• Health professionals and aged care providers.
• National and international policymakers.
• The World Health Organization and public health monitoring bodies.
• Researchers and educators in ageing and health sciences.

This transformative research underscores Charles Sturt University’s commitment to leading health innovation that supports inclusive, empowered, and healthy communities.
