Elderly people's definition of quality of life

Senescence for some elderly people is a phase of with development and satisfaction, whereas for others is a negative stage of life. The determinants of a good quality of life in old age vary from person to person. The aims of this study were to identify 1) the prevalence of octogenarian people who evaluate their current life as being mainly characterized by a positive quality and 2) which were the domains that they identified as being the determinants of this positive quality. A same parallel study was conducted with subjects who evaluated senescence as a preponderantly negative experience.

A random and representative sample of 35% of the octogenarian people, living residing in the community, was selected among the dwellers of the city of Veranópolis, state of Rio Grande do Sul. A semi-structured questionnaire on quality of life quality was applied as well as the scale of depressive symptoms Geriatric Depression Scale (GDS) and the index of general health Cumulative Illness Rating Scale (CIRS).

Slightly more than half of the studied sample (57%) defined their current quality of life with positive evaluations, whereas 18% presented a negative evaluation of it. A group 0f 25% defined their current lives as neutral or having both values (positive and negative). Those who were dissatisfied presented more health problems according to the CIRS and more depressive symptoms when evaluated by the GDS. Satisfied subjects ones had different reasons to justify this state, however, the dissatisfied had mainly the lack of health as a reason for their suffering. The main source of reported daily well-being was the involvement with rural or domestic activities. Among the interviewed, lack of health was the main source for not presenting well-being, although there was interpersonal variability regarding what each subject considered as loss of health.

Possibly, for the elderly subjects a negative quality of life is equivalent to loss of health and a positive life quality is equivalent to a greater range of categories such as activity, income, social life and relationship with the family, categories which differed from subject to subject. Therefore, health seems to be a good indicator of negative quality of life, though an insufficient indicator of successful elderliness.
