The significance of personality factors for various dimensions of life quality among older people.

Quality of life has various dimensions with multiple meanings for people. One vital issue is whether a person's subjective experienced quality of life correlates with his or her personality. Several studies show a correlation between personality and quality of life, life satisfaction or well-being. The aim of this study was to examine the relationship between personality and life quality, in particular the way in which multi-dimensional conceptualization of personality relates to a multi-dimensional definition of life quality. Seventy-eight elderly individuals completed a quality of life questionnaire, the Lund Gerontology Centre's Life Quality Questionnaire (LGC), and a personality questionnaire, the Gordon Personal Profile Inventory (GP:A). Discriminant analysis showed that various personality characteristics relate to different aspects of life quality. Vigour alone predicted current quality of life, while emotional stability was related to psychological well-being and satisfaction with significant relationships. Ascendancy and ability to maintain personal relations were related to an optimistic outlook on life and absence of psychosomatic symptoms. Original thinking and sociability related to increased psychosomatic symptoms and sociability also correlated negatively with satisfaction with significant relationships. The results support the idea that various personality characteristics are related to various life quality dimensions in the investigated group, increasing the understanding of unique experience of life quality for each individual.
