Thriving: a life span theory

There is a need for aging theories to become holistic and multidisciplinary with a life span focus. A theory is the construction of explicit explanations in accounting for empirical findings. A good gerontological theory integrates knowledge, tells how and why phenomena are related, leads to prediction, and provides process and understanding. In addition, a good theory must be holistic and take into account all that impacts on a person throughout a lifetime of aging. Based on these criteria, the authors created the Theory of Thriving, with a holistic life span perspective for studying people in their environments as they age. This article proposes a theory for studying people over time in a holistic, encompassing manner.
