Trends and profiles of psychological functioning in very old age

Describes psychological and psychosocial status of the Ss of the Berlin Aging Study. In the 1st section, age trends are outlined in 3 domains: intelligence, self and personality, and social relationships. In the domain of intelligence, negative age differences between 70-103 yrs were substantial and were closely associated with indicators of biological deterioration. In contrast, age-related differences in personality, self-related beliefs, and social relationships were fewer and considerably smaller. (from the chapter); Interindividual differences, especially age/cohort differences, sources of interindividual and age-related variation, and the systemic interrelationships between the 3 domains of psychological functioning were examined.; Cluster analysis was used to identify 9 subgroups of older individuals with different patterns of functioning across 3 psychological domains. Four of these groups reflected various patterns of desirable functioning, and five, less desirable functioning. The relative risk of membership in the less desirable profile subgroups was 2.5 times larger for the very old (85-103 yrs) than for people between the ages of 70-84 yrs, and 1.3 times larger for women than for men.
