Active aging has been a challenging goal that is being explored and pursued by countries all over the world. Effectively establishing active aging for the elderly is a social and cultural process that requires policy framework and planning. The elderly are at the core of the active aging strategy, although families, communities, and society are also essential components in its utilization. However, the adoption and practice of active aging have continuously developed in different ways and with different characteristics all over the world. Some of the traditional aspects in the active aging policy framework are daily activities for the elderly, health protection, and life expectancy. However, the modern senior population has ability to take active part in social and political processes, so the rights to independent development must also be considered. Therefore, this study used the analysis steps of Walker and Avant (2005) to describe the definitional features of an intermediate period, case report, the results and their causes, and measurement tools for active aging. The definitional features of active aging including healthy life extension, empowerment to participate in social activities, work consciousness and economic stability, self-confidence and safe quality of life, and have self-confidence and respect. Finally, the directions of the evidence-basic measurement tools of the national level active aging index and the individual level active aging assessment scale. A multidimensional perspective was used to explain the concept of active aging. The results could help health care team members to understand and apply the concept in health care practice for the elderly, and empowerment of the elderly could help to achieve the overall goal of ''active aging.''
