Physical, Cognitive, and Psychosocial Variables From the Disablement Process Model Predict Patterns of Independence and the Transition Into Disability for the Oldest-Old

By understanding the physical, cognitive, and psychological variables that predict whether a person develops a disability within the next 2 or 4 years, we may be better able to plan for care or implement appropriate interventions.
