| Annotation | A series of hierarchical regression models was used to determine if time of death was a significant independent variable for level and 7-year change in intellectual performance for 1,214 community-dwelling adults in the Seattle Longitudinal Study (SLS). Distance to death explained a significant amount of the variance of intellectual performance at individuals' last measurement, but not of the decline in performance after controlling for age, education, gender, and survivorship. The inclusion of time of death improved the proportion of unique variance explained by about 1% to 3% and between 4% and 10.4% of the total variance explained. Decedents had lower levels of verbal meaning (recognition of vocabulary), spatial ability, reasoning ability, and psychomotor speed at last measurements and greater amounts of 7-year decline on verbal meaning and psychomotor speed. The inclusion of distance to death may help improve the explanation of variability in performance associated with increased age. (RH). |
