This paper investigates predictors of life satisfaction and quality of life among severely disabled elderly adults. Markides and Martin's (1979) path analysis model was adapted specifically to elderly persons with severe disabilities. The study group comprised 97 patients discharged from three medical rehabilitation facilities in metropolitan Boston during 1984. The adapted model explained about 40% of the variance in quality of life among both men and women, with functional capacity being the most important predictor.

We examined the effectiveness of using diagnosis related groups (DRGs), Severity of Illness Index (SIt), age and function at admission to predict inpatient charges for medical rehabilitation. Data from our sample of 199 indicate that DRGs alone explained approximately 12 per cent of the variation in charges for inpatient rehabilitation while SII explained 26 per cent of the variation. 51, DRG, and age together yielded the highest regression coefficient, accounting for nearly 39 per cent of the variation in total charges; S11 and age accounted for 36 per cent of the variation. IntroductionThe prevalence of disability in the United States has increased over the past 20 years.
