Background: Studies on the self-efficacy of the elderly are still being conducted to a very limited extent. Nevertheless, they can provide relevant information for specialists to use in many disciplines of science, as well as for practitioners, especially gerontologists, geriatricians, psychologists and other people associated with prophylaxis and health promotion. The aim of the study is to assess the impact of the place of residence and marital status on the self-efficacy in the elderly. Methods: A diagnostic survey method was used for the study and within the method, the authors' sociodemographic data questionnaire and the generalized self-efficacy scale (GSES) were applied. The study was carried out in a group of 171 females and 130 males under nursing care in the home environment or in nursing-home care in Poland. Results: The average level of generalized sense of self-efficacy in the research cohort was M = 26.69, SD = 8.49. A relatively high percentage of the group (48.9%) showed a sense of self-efficacy at a high level. The level of a sense of self-efficacy was low in 38.2% of the cohort, while its average intensity in the remaining ones constituted 12.9% of the total. A statistically significant impact of a place of residence (Z = -2.940; p = 0.003) and marital status (H = 12.000; p = 0.007) on the sense of efficacy in the research cohort was proven in favor of those from the rural environment and the respondents having spouses. Conclusions: On the scale of the studied group, the results of a sense of self-efficacy are optimistic, as older people with high levels predominated. However, the results of the cohort whose self-efficacy is insufficient to cope with their old age should be considered carefully, especially in the case of lonely people living in the urban environment and NHC (nursing-home care) residents.
