Social science of ageing

Disengagement theory is the idea that separation of older people from active roles in society is normal and appropriate, and benefits both society and older individuals. Disengagement theory, first proposed by Cumming and Henry, has received considerable attention in gerontology, but has been much criticised.[45][46] The original data on which Cumming and Henry based the theory were from a rather small sample of older adults in Kansas City and from this select sample Cumming and Henry then took disengagement to be a universal theory.[47] There are research data suggesting that the elderly who do become detached from society are those who were initially reclusive individuals and such disengagement is not purely a response to ageing.[45]
Activity theory, in contrast to disengagement theory, implies that the more active elderly people are, the more likely they are to be satisfied with life. The view that elderly adults should maintain well-being by keeping active has had a considerable history and since 1972, this has come to be known as activity theory.[47] However, this theory may be just as inappropriate as disengagement for some people as the current paradigm on the psychology of ageing is that both disengagement theory and activity theory may be optimal for certain people in old age, depending on both circumstances and personality traits of the individual concerned.[45] There are also data which query whether, as activity theory implies, greater social activity is linked with well-being in adulthood.[47]
Selectivity theory mediates between the activity and disengagement theories, and suggests that it may benefit older people to become more active in some aspects of their lives, more disengaged in others.[47]
Continuity theory is the view that in ageing people are inclined to maintain, as much as they can, the same habits, personalities and styles of life that they have developed in earlier years. Continuity theory is Atchley's theory that individuals, in later life, make adaptations to enable them to gain a sense of continuity between the past and the present and the theory implies that this sense of continuity helps to contribute to well-being in later life.[11] Disengagement theory, activity theory and continuity theory are social theories about ageing, though all may be products of their era rather than a valid, universal theory.
