Profiles of psychological functioning in the old and oldest old.
Authors:Smith, Jacqui   Baltes, Paul B.
Abstract:
Cluster analysis was applied to 12 measures of intellectual, personality, self-related, and social functioning collected in the 1st cross-sectional wave of the Berlin Aging Study (BASE; N?=?516). Central questions concerned the number, profile desirability (functional status), and membership of the subgroups obtained. Of the 9 subgroups extracted, 4 reflected different patterns of desirable functioning (47% of the sample), and 5 reflected less desirable functioning (53%). Relative risk of a less desirable profile was 2.5 times higher for the oldest old (85–103 years) than for people between the ages of 70–84 years and was 1.25 times higher for women compared with men. Relationships with education, health, and mortality suggested underlying systemic differences. Consistent with theoretical propositions about a "4th age" and the incomplete architecture of life span development (P. B. Baltes, 1997), the oldest old appear to have a distinct and less desirable psychological profile. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
