Coping resources and selective survival in mental health of the elderly.

Analysis of longitudinal data (1975-1984) from the Cleveland GAO study shows that physical health and social support emerge as major coping resources for forestalling decline in mental health among the elderly over a nine-year period. However, social resources and poorer self-assessed physical health, which are significant predictors of decline in emotional health, have no effect in loss of cognitive ability, suggesting a biological component in such loss. However mortality over the nine-year time span is related to poorer initial mental health and cognitive ability, thus revealing that selective survival masks the extent to which mental conditions decline over time, with impaired White males the least likely to survive. Although measures of mental health and cognitive skills play a major role in predicting mortality, taken together they are less significant in explanatory power than the availability of social resources.
