The present study aimed to investigate the correlation between the sense of belonging and ERA in elderly adults. An important finding of the research was the appropriate level of the variables of sense of belonging and ERA. Furthermore, the multiple regression results demonstrated that the sense of belonging was positively correlated with all the dimensions of ERA. In a study in this regard, Sarkisian reported the mean score of ERA in three groups of elderlies (American, African-American, and non-American Caucasians), and the results are consistent with the present study (
16). Furthermore, Li et al. (
17) proposed congruent findings in this regard in an elderly population in China. On the other hand, Kim (
9) reached an inconsistent conclusion with the present study, reporting the ERA to be relatively poor in the elderly in Korea.
Several studies have confirmed the significant effects of the expectation regarding positive and negative aging on lifespan and the quest for health care (
18-
20). Unfortunately, we could not properly address the tendency to longevity in the current research, while as a potential factor, it highlights the need for further investigating ERA.
Some studies have also been focused on the sense of belonging in various populations, such as students (
21), older adults (
22), and adults (
23), and their positive findings in this regard are consistent with the present study. Psychologically, evolutionarily, and biologically, humans are social beings, and many of their needs have been met through interactions with others throughout the biological history of mankind. As such, sense of belonging is an important factor in satisfying human needs, which could justify the consistency of our findings with the similar studies conducted on various populations (
11).
Another important finding of the present study was the significant, direct correlation between the sense of belonging and ERA in the elderly. According to the available databases, this was the first study regarding this subject matter. According to our findings, the sense of belonging could predict ERA. The intimate relations of the elderly with their family members could result in healthier aging. Previous findings have also denoted that the appropriate communication of the elderly in social environments (with family or peers) could further engage these individuals socially, thereby reducing their unemployed time, as well as the risk of depression and other mental disorders, which in turn promotes their overall health (
24). On the other hand, the higher ERA in the elderly could influence their sense of belonging, thereby forming a positive cycle through which their desire and tendency to have more friends could be strengthened in the process of aging; this has been confirmed in a study conducted by Menkin et al. (
25) on the elderly in the United States. Therefore, special attention should be paid to ERA as an important variable; according to the report by Low et al. (
26), the promotion of ERA ultimately improves the quality of life of the elderly.
In the present study, the correlations between demographic variables such as age, gender, marital status, education level, economic status, and visiting relatives with ERA were also investigated, and only economic status could predict ERA. Various results have been reported in this regard; in the studies by Sarkisian et al. (
16) and Menkin et al. (
25), education level has been reported to be significantly correlated with ERA. Evidently, discrepancies could be attributed to the cultural differences (e.g., livelihood and economic issues, quality of life, social welfare) and lifestyle of the elderly in the mentioned studies. In the study by Bowen et al., education level could not predict ERA, and economic status was not significantly correlated with ERA (
18).
5.1. Strengths, Limitations, and Suggestions
This was the first study conducted in this regard in Iran, and the findings could lay the groundwork for the further investigations. The present study had some limitations, such as the small sample size, low standard deviation in the age variable, possibility of cultural differences among the elderly that could affect the results and limit generalizability, and lack of similar studies for standard comparison. Therefore, it is suggested that further studies be carried out, and randomized clinical trials (RCTs) be conducted to determine the impact of training on the development of emotional skills on ERA in order to provide accurate results for the community. Due to different living conditions, the Iranian elderly living in other countries are also an appropriate group for the comparison of results obtained within the country.
5.2. Research Implications
The results of the present study could be used by researchers to design further investigations. Considering the impact of mental health on the other aspects of geriatric health, the importance of the subject matter, and lack of similar studies, further studies are required in this regard in Iran. In addition, proper training should be provided in this respect to nursing students and geriatric nursing senior students given their direct contact with the elderly population in educational centers and universities. Finally, the elderly and their families should also be educated in order to take a step toward improving their quality of life.
5.3. Conclusions
According to the results, the levels of ERA and sense of belonging in the elderly were acceptable. Furthermore, these variables had a direct, significant correlation. Economic situation could also predict ERA. Our findings could be incorporated into the design of comprehensive studies and RCTs to obtained accurate results.
