Contributions of Psychosocial Factors and Physical Activity to Successful Aging

Abstract

The aim of this study was twofold: (a) To validate a successful aging model in a Spanish older adult's sample, and (b) to predict successful aging from psychosocial factors and physical activity. Participants were 725 Spanish older people, of whom 478 were women and 247 men, aged between 55 and 100 years. Of these, 501 were physically active and 197 persons did not practice physical activity. The sample was collected in three areas: Sport centers, day centers and public areas of several Spanish towns. Factorial validity of the Successful Aging Inventory was studied by confirmatory factor analysis, and four multiple regressions to predict each of the dimensions of successful aging (functional performance, intrapsychic factors, gerotranscendence, and spirituality) were estimated. The model of successful aging in Spanish elderly through the Successful Aging Inventory was adequate. The four multiple regressions predicted highly successful aging, with effect sizes of: R2 = .037 for spirituality; .267 for functional performance; .531 for intrapsychic factors; and .356 for gerotrascendece. A main conclusion derived from the results is that older people who do exercise achieve better aging. Another point is that aspects of health and life satisfaction are directly related to better aging while social aspects influence indirectly.
