Longitudinal data from the Health and Retirement Study support the concept that disability reflects a progression from disease to impairment to functional limitation and finally to disability.

Over and above absolute level, increases in self-efficacy and outcome expectancy were significant predictors of decreases in symptoms and increases in functioning. Implications for treatment are discussed, as well as future directions of research.

Trends should continue to be monitored closely for both groups, since younger people have not experienced the improvements of the older group, but are its future members.
