Quality of life of older adults is influenced by multiple environmental factors. The purpose of this study was to examine the relationships of quality of life and internal environmental factors (physical functioning, and depressive symptoms), and external environmental factors (social support satisfaction and social network density). The study framework was based on the Complexity Theory and the Human Response Model.
A cross-sectional predictive design was used to study the residents of retirement communities or people who attend senior centers in Northeast Ohio. Data collection involved the Short Physical Performance Battery, the Geriatric Depression Scale, the Arizona Social Support Interview Schedule, and the Quality of Life ICECAP index. This study was approved by the Case Western Reserve University's Human Subjects Review Board.
Total sample size was 95. Data analyses indicated 62% of the sample was female, 78% were white, 90% were non-Hispanic, 86% lived at home, 63% lived alone, 73% were drivers, 89% completed high school or higher, and subject age ranged from 65 to 96, with the average age of 76 years. Descriptive statistics are as follows: physical functioning was high (M =8.95, SD = 2.49); quality of life was high (M = .84, SD =.11); depressive symptoms were low (M = 1.98, SD = 2.42); social support satisfaction was high (M = 35.67, SD = 6.18); and social network density was moderate (M = .53, SD = .33). Physical functioning was significantly higher in participants who completed college or higher than those who complete high school or less, and higher in participants who lived with others than those who lived alone. Depressive symptoms were significantly lower in the drivers than non-drivers/drivers with constraints. Hierarchical regression analysis shows that predictor variables explain 32% of variance in the quality of life of older adults (R2adj = .32, F(11, 83) = 4.95, p < .001). Physical functioning (β = .26, p < .05) and depressive symptoms (β = (open full item for complete abstract)
