Engagement with an old theory

The co-author of Disengagement Theory restates the central propositions, suggests new studies that might test its usefulness, and examines some of the controversy that has been generated over the years either by the theory itself or the context in which it was set forth. The four key propositions focus upon decreasing life space with advancing age, the individual's own anticipation and participation in this process, a change in style of interaction, and the momentum of the disengagement process once it has begun. Although some useful research has been done, the theory remains poorly operationalized and largely untested. A measure of life space variety is proposed, and attention also directed to neuro-physiological findings. Several misunderstandings and misapplications of Disengagement Theory are discussed, including the erroneous idea that disengaged people necessarily are either higher or lower in morale than others, and the unenlightening controversy over "activity versus disengagement."
