Foundational perspectives of sociology can be applied to aging and gerontology — the study of old age, the process of aging, and the particular problems of older populations. But with any field, demographic, or topic, more specific theories offer a closer look. Continuity theory, disengagement theory, and activity theory all focus on explaining age in different ways. They are direct contrasts from each other and can be helpful when discussing social problems people experience as they age.
Continuity Theory
Middle-aged and older adults use adaptive measures to promote mental and physical continuity. Continuity theory is a micro-level psychosocial theory connected to aging. Continuity theory states that older adults maintain activities, behaviors, and relationships they had in young adulthood and adulthood, and this connects them to a sense of familiarity that increases life satisfaction.
