Investigation of relationship between functional level, cognitive status, emotional status, and quality of life in elderly people living at home

Purpose: This study was planned to investigate the relationship between cognitive status, depression level, functional status, and quality of life in elderly people living at home. Methods: One hundred thirteen voluntary elderly subjects living at home participated in this study. Demographics of the participants were recorded. The data was obtained by face-to-face interviews. The questionnaire covered socio-demographic characteristics, administration of the Standardized Mini Mental Test (SMMT), Geriatric Depression Scale-Short Form (GDS-SF), Lawton Instrumental Activities of Daily Living (IADL) Scale, Katz Index of Independence in Activities of Daily Living (ADL) and World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-OLD). Results: The mean age was 71.4 +/- 5.9 years. Ninety two percent of the elderly subjects were independent in ADL, whereas 83.2% were independent in IADL. The subjects had a high cognitive level (8.63 +/- 1.57) and low depression status (4.09 +/- 3.17). Also, there was a positive correlation between ADL, IADL, cognitive status, and quality of life (p<0.05) and a negative correlation between ADL, IADL, cognitive status, and depression status (p<0.05). Conclusion: This study indicated importance of the relationship between functional level, cognitive status, depression level, and quality of life in the rehabilitation of elderly people living at home.
