A 13-Year Time-Lagged Description of General Cognitive and Functional Abilities in Older Men
Objectives: The purpose of this study was to evaluate a cross-lagged panel model of general cognition and functional abilities over 13 years. The goal was to determine whether general cognitive abilities predict or precede functional decline versus functional abilities predicting cognitive decline. Methods: The sample included 3508 men (71-93 years of age at baseline) of the Kuakini Honolulu-Asia Aging Study who were tested repeatedly using a glo…
A Cultural Comparison of Personality Profiles of U.S. and Japanese Centenarians
The purpose of this study was a cross-cultural examination of centenarians’ personality through a person-centered approach to examine if there is a “resilient” personality profile consistent across cultures. Proxy reports information was obtained from family and close friends of 239 U.S. centenarians from the Georgia Centenarians Study and 272 Japanese centenarians from the Tokyo Centenarian Study. Latent profile analyses were conducted to identi…

Defining Successful Aging
PURPOSE OF THE STUDY: Everyone wants to age successfully; however, the definition and criteria of successful aging remain vague for laypersons, researchers, and policymakers in spite of decades of research on the topic. This paper highlights work of scholars who made significant theoretical contributions to the topic. DESIGN AND METHODS: A thorough review and evaluation of the literature on successful aging was undertaken. RESULTS: Our review inc…
Examination of Important Life Experiences of the Oldest-Old
Evaluation of the Religiosity in 5-D Scale
The goal of this study was to evaluate the factor structure and measurement equivalence of the Religiosity in 5-D Scale (Faulkner & DeJong, 1966). Using 262 participants from the Georgia Centenarian Study (Poon et al., 1992), analyses included exploratory factor analyses without rotation and using rotation, confirmatory factor analyses of a multiple and single factor religiosity construct, the establishment of measurement equivalence across age g…
Influence of Personality and Health Behaviors on Fatigue in Late and Very Late Life
There is limited understanding about variables associated with fatigue in late and very late life. The purpose of this study was to explore the longitudinal influences of personality and health behaviors on changes in fatigue. One hundred and seventy-eight participants of the Georgia Centenarian Study were part of this study. Multiple regression analyses were computed to assess the influence of personality, physical activity, stress management, a…
Self-perception of aging and health among older adults in Korea
Age Changes and Differences in Personality Traits and States of the Old and Very Old
The purpose of this study was to examine stability and change in personality traits and states for 3 age groups: centenarians, octogenarians, and sexagenarians. One hundred seventy-nine older adults participated in the 2-wave study. Results concerning age-group differences indicated that centenarians scored higher in Suspiciousness but lower in Intelligence and Stress when compared with the other 2 age groups. Octogenarians were lower in the pers…
A Molecular View of Coping Behavior in Older Adults
The findings suggest that a molecular view of specific coping behaviors in reaction to health problems, in addition to global measures of coping, is essential
Cognitive Functioning in Centenarians
Cognitive functions among centenarians in Japan, Sweden, and the United States are described. Three areas are explored. First, definitions and prevalence of dementia are compared between Japan and SWEDEN: Second, levels of cognitive performances between centenarians and younger age groups are presented. Third, interindividual variations in cognitive performances in centenarians and younger persons are compared in Sweden and the United STATES: The…
A Model of Loneliness in Older Adults
Loneliness and physical health status in older adults have been correlated strongly but the predictive direction is unclear. This study examined the relationship between personality, cognition, social network, and age modeled as predictors of loneliness in older Americans. Self-assessed health mediated the relationship. The sample consisted of 208 independently living individuals 60 to 106 years of age from the southern region of the United State…

Factors of Nutritional Health-Seeking Behaviors
Health-seeking behaviors are described by Harris and Guten (1979) as any behavior of an individual that promotes, protects, or maintains one's health, regardless of actual or perceived health status. The purpose of this study was to determine if nutritional health-seeking behavior (Bausell, 1986) comprised one or more factors for older adults (N = 256). Participants were in their 60s (n = 90), 80s (n = 91), and 100+ (n = 75). Exploratory factor a…

Older Women's Financial Resources and Perception of Financial Adequacy
Data from the Georgia Centenarian Study were used to investigate sources and amounts of older women's financial resources and their perception about the adequacy of those resources. The findings revealed that age, marital status and race have an impact on women's financial resources. Centenarian women had the highest poverty rate. Six times as many black as white women received Supplemental Security Income. The poverty rate for black women approa…

Locus of Control and Vasomotor Response to Sensory Processing
Heart rate and forearm blood flow responses were measured during experimental tasks requiring sensory intake, sensory rejection, and a mixture of the two behaviors. Subjects were 29 college students who had been categorized using Rotter's locus of control scale. Significant increases in both cardiovascular indices were seen in all three tasks; the responses were smaller, however, during sensory intake. Internals showed a differential response of …
