A Shift from Objective Measures to Subjective Well-being
For decades, the concept of successful aging in gerontology was heavily influenced by objective, biomedical criteria, such as the famous model by Rowe and Kahn. Their framework prioritized three main components: low probability of disease and disability, high physical and cognitive function, and active engagement with life. However, critiques quickly arose for being overly restrictive and failing to capture the lived experiences of many older adults, particularly those with chronic health conditions.
Scoping reviews, which systematically map existing evidence, have been instrumental in re-centering the definition around older adults' own perspectives. Instead of adhering to an exclusive, achievement-based model, older adults embrace a more holistic and adaptive view. They perceive themselves as aging successfully despite physical limitations, demonstrating that successful aging is not an outcome to be achieved but a process of adaptation and coping.
The Multidimensional Pillars of Successful Aging
Scoping reviews have consistently identified several core dimensions that older adults emphasize when defining successful aging. These go far beyond simple physical health and functional capacity.
Psychosocial and Emotional Health
This domain is perhaps the most heavily weighted by older adults. It includes a variety of factors that contribute to mental and emotional resilience.
- Positive Coping Strategies: The ability to adapt and cope with age-related changes and challenges is a cornerstone. This includes managing losses and maintaining a positive attitude despite difficulties.
- Life Satisfaction: Feeling content and satisfied with one's life, including a sense of contentment with past choices and present circumstances.
- Self-Acceptance: Older adults value accepting themselves as they are, acknowledging their limitations without letting them define their entire worth. Self-determination is a key element.
- Wisdom: Research also links wisdom, accumulated over a lifetime of experience, with how older adults perceive successful aging.
Social Connection and Engagement
Maintaining meaningful social relationships and staying engaged with the world is a vital component. Social ties provide support and a sense of belonging that enriches later life.
- Strong Social Networks: This includes relationships with family, friends, and neighbors, which provide both emotional and instrumental support.
- Active Community Involvement: Participation in a variety of activities, such as volunteering, joining community groups, and engaging in lifelong learning, is highly valued.
- Spirituality and Meaning: For many, engaging in religious or spiritual activities provides a sense of meaning and purpose in life.
- Avoiding Isolation: Scoping reviews underscore that strong social ties act as a protective factor against the negative mental and physical effects of isolation.
Adaptation to Physical Changes
Unlike the objective criteria of traditional models, older adults' perspectives emphasize function and adaptation rather than perfect health. The goal is to maintain independence and daily function for as long as possible, even in the presence of chronic illness or disability.
- Maintaining Functional Capacity: The ability to perform daily activities, even with modifications, is more important than the absence of disease.
- Physical Activity: Regular, appropriate physical activity is seen as a means to maintain mobility and overall health, not as a marker of perfect health.
Personal Meaning and Purpose
A sense of continued purpose and growth, regardless of age, significantly influences older adults' perceptions.
- Productive Activities: Engaging in paid or volunteer work, hobbies, and other meaningful pursuits keeps older adults feeling valuable and contributing to society.
- Ongoing Growth: The belief that one can continue to grow, learn, and develop throughout life is a key aspect of successful aging from the lay perspective.
Older Adult vs. Biomedical Perspectives: A Comparison
To highlight the difference in perspective, let's compare the defining aspects of successful aging from an older adult's viewpoint versus a traditional biomedical model.
| Aspect | Older Adult Perspective (Subjective) | Biomedical Model (Objective) |
|---|---|---|
| Physical Health | Adaptation and coping with illness; maintained function despite limitations. | Absence of disease and disability; high physical function. |
| Psychological State | Resilience, positive attitude, self-acceptance, life satisfaction. | Minimal depressive symptoms; high cognitive function based on tests. |
| Social Life | Meaningful social relationships; feeling connected and valued; community engagement. | High frequency of social interaction; participation in specified activities. |
| Process | A dynamic process of adapting to life's challenges. | An outcome achieved by meeting a strict set of criteria. |
| Focus | Holistic well-being (mind, body, and spirit). | Physical and cognitive function as primary indicators. |
The Impact of Social and Cultural Context
Scoping reviews also bring to light that the definition of successful aging is not universal and is shaped by an individual's social and cultural context. Factors like socioeconomic status, gender, and cultural background play a significant role. For instance, collective cultures may emphasize family ties and intergenerational support over the individual autonomy valued in Western societies.
Furthermore, the availability of resources, such as access to affordable healthcare and financial stability, heavily influences an older adult's ability to pursue their version of successful aging. Socioeconomic inequalities can create significant barriers, highlighting that successful aging is not simply a matter of individual choice but is profoundly affected by broader societal structures.
How Scoping Reviews Inform Health Promotion
Understanding how older adults define successful aging provides a powerful roadmap for developing more effective health promotion policies and interventions. Instead of focusing solely on disease prevention, programs can emphasize building resilience, fostering social connections, and promoting a sense of purpose. This approach is more likely to resonate with and empower older adults, leading to greater well-being.
By systematically synthesizing the voices of older adults themselves, scoping reviews ensure that research and policy reflect the reality of aging.

Conclusion: A More Inclusive Definition of Success
The findings from scoping reviews offer a richer, more inclusive definition of successful aging. By moving beyond rigid, biomedical criteria, we gain a deeper appreciation for the complex, personal, and subjective journey of aging. For older adults, success is not the absence of challenges but the ability to adapt, maintain a positive outlook, nurture relationships, and find purpose despite them. This reframing not only honors their experience but also offers a more compassionate and practical framework for promoting health and well-being in later life.
