Abstract:Objective To investigate the correlation between family function and self-efficacy (SE) among elderly adults in home-based setting in Guiyang. Methods A questionnaire survey was conducted by the application of Multistage stratified random method. General information, general SE scale and the family-concern index were recorded in 1905 elderly adults in home-based setting in Guiyang city, Guizhou province. Results The mean score of SE was (25.46 ± 7.23) in elderly adults in home-based setting. Age, education background, income and physical exercise had an effect on SE (P < 0.05). The mean score of family function was (7.62 ± 2.34). Totally 1262 (66.25%) elderly adults presented good family function, 577 (30.29%) elderly adults presented moderate family dysfunction, while 66 (3.46%) elderly adults presented a high level of family dysfunction. Correlation analysis showed that SE was positively correlated with their family functions in elderly adults in home-based setting (r = 0.209, P = 0.000). Conclusion SE of elderly adults in home-based setting in Guiyang needs to be improved. Society should focus more on those who are oldest-old, less-educated, low income and no more exercise. There is close relationship between the family function and self-efficacy in elderly adults. More intervention studies should be launched to enhance the family function.
