The Engage-Disengage Model as an Inclusive Model for the Promotion of Healthy and Successful Aging in the Oldest-old

Theories relating to healthy and successful aging do not specifically cater for the oldest-old. This predominantly theoretical research considers the relevance of existing healthy and successful aging theories in the oldest-old. It explores a small sample of interviews of independently living oldest-old using Differential Qualitative Analysis. The Activity Theory and the Disengagement Theory were particularly relevant to investigate differences. The Engage-Disengage model was conceived as a pragmatic holistic model to address specific challenges facing the oldest-old. Engage-Disengage reflects attainable healthy and successful aging in the oldest-old according to individual abilities (intrinsic physical and mental capacities), values, and external resources (social, material, and environmental).
