Objectives
The aim of this cross-sectional study was to determine the life satisfaction of older people living in a home environment and to find out what predictors influence it.
Methods
The research involved 1,121 older people 60 years and above from the Moravian-Silesian region who live in a home environment. The short form of the Life Satisfaction Index for the Thirds Age (LSITA-SF12) was used to assess life satisfaction. The Geriatric depression scale (GDS-15), the Geriatric Anxiety Inventory Scale (GAI), The Sense of Coherence Scale (SOC-13), and the Rosenberg Self-Esteem Scale (RSES) were used to evaluate related factors. In addition, age, gender, marital status, education, social support, and subjective health assessment were evaluated.
Results
The overall life satisfaction score was found to be 36.34 (s = 8.66). The satisfaction of older people was classified into four grades: high satisfaction (15.2%), moderate satisfaction (60.8%), moderate dissatisfaction (23.4%), and high dissatisfaction (0.6%). The predictors of the longevity of the lives of older people were confirmed, both health factors (subjective health assessment, anxiety, and depression [Model 1: R = 0.642; R2 = 0.412; p<0.000]) and psychosocial factors (quality of life, self-esteem, sense of coherence, age, and social support [Model 2: R = 0.716; R2 = 0.513; p<0.000]).
Conclusion
In implementing policy measures, these areas should be emphasized. The availability of educational and psychosocial activities (e.g. reminiscence therapy, music therapy, group cognitive behavioural therapy, cognitive rehabilitation) within the community care of the older people and university of third age is appropriate to increase the life satisfaction of the older people. An initial depression screening is also required as part of preventive medical examinations to ensure early diagnosis and treatment of depression.
