Happiness is considered a positive inner experience originating from individuals’ cognitive and emotional interpretation of their lives [1]. As indicated in this definition, happiness is also an all-encompassing concept underlain by two components, namely, emotion and cognition. The emotional component refers to pleasure (balance between pleasant and unpleasant affect), and the cognitive component pertains to mental health [2]. Considering outcomes related to happiness, a number of studies have suggested that a sense of happiness can be used as a basis for treating mental disorders, increasing hope, developing psychological resistance, and reinforcing defensive power against stress [3]. The effectiveness of using happiness as a pathway to treatment is supported by publications such as the World Health Organization’s World Happiness Report, which ranked Iran as the 107th happiest nation among 155 countries in 2017. The country exhibits a higher happiness rate than Iraq and Afghanistan and a lower happiness rate than its other neighbors, such as Turkey, Pakistan, Azerbaijan, and Arab countries [4].

Similar to happiness, old age is experienced as one of the inevitable events in human life by a considerable proportion of the population in different communities [5]. Old age comes with the debilitation of physical and spiritual strength, thereby placing the elderly in a highly vulnerable position. The elderly can also suffer from problems such as loneliness, depression, anxiety, and, eventually, physical and mental disorders because of the “automated” life currently characterizing the modern world, residence in apartments or small homes, reduced number of children, children’s immigration to other cities, and the consequent distance of any of them from their parents [6]. These issues highlight the need to pay attention to the elderly age group, provide them with necessary support, and investigate and evaluate their needs in all of life’s dimensions. One such dimension is social support received from family or friends [7]. Research has demonstrated that factors such as levels of interaction and social support can affect the satisfaction and general health of elderly people [8]. Social support refers to assistance or support provided by members of social networks to an individual [9]. Rathus [10] believed that social support can adjust and diminish the unfavorable effects of mental pressure. The author also described different types of support: (1) emotional support, which involves listening to individuals’ difficulties and showing empathy, care, understanding, and reassurance; (2) instrumental support, which pertains to provision of tangible assistance that a person needs; (3) informational support, which is the delivery of guidance and advice to increase the coping skills of individuals; and (4) appraisal support, which refers to the provision of feedback by others concerning quality of functioning and thus leading to corrected functioning [10]. Janevic et al. [11] in 2004 concluded that informational support, emotional support, mutual positive social action, tangible support, the number of close friends and relatives, and marital status are significantly correlated with the health status of elderly women. Investigations have also showed a significant and positive relationship between social support and happiness [11]. Countries provide different types of support to their elderly populations. In Iran, for example, the Ministry of Health and the Welfare Organization and Relief Committee provide elderly counseling services and food basket donations, implement the house caretaker and Shahid Rajaee plans, and exempt elderly caregivers from tax and insurance payments [12]. Despite these initiatives, Iran is confronted with a lack of studies devoted to the circumstances and living conditions of the elderly. Such explorations are important given the increasing population of elderly individuals and the necessity of understanding the factors that affect old people’s quality of life. Accordingly, the present research was conducted to examine the effectiveness of social support for the elderly of Iran and determine the magnitude and importance of each social support structure on the elderly. The findings can serve as a reference in formulating strategies for care planning and intervention at the individual and group levels. It is hoped that these strategies will improve the quality of life and health of the elderly.

Of the 411 participants, 74% were men and 88.3% were married (Table 1). The mean age of the respondents was 64.89 years (standard deviation [SD], 4.59). The other demographic characteristics of the participants are presented in Table 1.

As shown in Table 2, the mean score for happiness among the respondents was 41.17. Out of the respondents, 47.32% reported being happy. The correlation between the different types of social support and happiness showed a significant relationship among all the study variables at a significance level of 0.01 (P=0.000).

Table 3 indicated that happiness was significantly and positively correlated with age (P=0.002), education (P=0.001), and income (P=0.001). The social support score in relation to these variables was 29.40. None of the demographic variables, except for marital status (P=0.005) and age (P=0.005), showed a significant relationship with social support. An increase in age could reduce the level of social support received by the elderly.

Table 4 presents the results of the multiple linear regression conducted on happiness, social support, and the demographic variables. The beta coefficient indicated that informational support was highly correlated with happiness. The R2 of the test was 0.255, indicating that 25% of the variance in happiness could be explained by social support and the demographic variables. The results of this study suggest that there is a significant relationship between happiness and two components of social support such as information and emotional support, even when controlling for confounding variables such as age, gender, and so on.

The purpose of this study was to investigate the relationship between social support and happiness among elderly people. Individuals endowed with favorable social support were expected to exhibit a more positive view toward life, a higher level of satisfaction, and better functioning than those who do not receive such support [16]. The results suggested a significant and positive relationship between the dimensions of social support (informational, appraisal, etc.) and happiness; that is, individuals receiving more social support had higher levels of happiness. The findings are consistent with those of similar studies [17]. The types of support that can be provided to the elderly include trust; emotional, informational, instrumental, appraisal, psychological, and financial support; the presence of kinship networks; a sense of belonging and affiliation; and understanding, sympathy, and friendship. Having positive effects on human life and consequently on human happiness, social support not only promotes health but also diminishes medical problems such as depression and anxiety [18]. Social support can drive improved health status provided that it establishes a sense of intimacy [19]. The protective effects of social support can result from several processes, such as positive access to information about health and healthcare services, encouragement of healthy behaviors, assistance in the use of healthcare services, and the provision of tangible assistance [17]. Living with family members, including spouses and children, and acquiring financial and emotional attention and support, create feelings of love, care, self-esteem, and value among the elderly, thus leading to a happy and healthy life. The results revealed that the sample receive above-average social support, consistent with the findings of Bozo [20].

The findings of the current work also suggested a significant relationship between social support and marital status and age. Marriage can create a sense of affection, love, and sympathy, which count as forms of social support that foster satisfaction and tranquility. Such feelings are absent or at low levels among unmarried individuals. The advantages of marriage as well as the density and quality of social support can likewise vary depending on culture. These results are in line with the findings of Heiydari et al. [21] Given the inverse relationship between age and social support, the results indicated that increased age could reduce the number of social networks and, subsequently, the level of subordinate social support among the elderly population [22]. This issue, along with the empty nest syndrome, the social characterization and context of today’s society, children’s concerns, and lack of opportunities to meet the needs of the elderly, can be another reason for the decline in social support with age. Gender was not significantly correlated with social support. The lack of difference in social support provided by family and friends to elderly men and women is attributed to Iranian and Islamic culture, in which respect for the elderly, especially parents, is of utmost importance. Thus, both male and female elderly individuals are revered by family and friends. The results showed no significant relationship between social support and education. The same was also true for income, family, and occupation. Given these results, individual differences in occupation, level of education, and income were disregarded as determinants of the level of social support provided to the elderly. Thus, these need not be emphasized in planning and policy making. In justifying the family dimension as a social network, it was concluded that the number of family members was not relevant merely because of the significance of communication skills and quality and social support.

In the current research, social support and its dimensions could predict happiness. The results are consistent with the findings of studies that confirmed the predictive power of social support for happiness [23]. In explaining these findings, it was assumed that relatives and strangers can act differently as they interact with elderly people; although family members always function as a source of emotional and instrumental support (e.g., money, gifts, and services), friends are unable to provide the same type of support [24]. However, informational and appraisal support can arise from both family members and friends [25]. The friends of elderly individuals can accompany them in social activities more frequently than can their children or other relatives. Considering the power of social support to predict happiness, social support could increase self-confidence, self-disclosure, and selfesteem in an individual, thereby helping him/her achieve goals, satisfaction with life, and, consequently, happiness.

Note that there are three social support aspects that affect a person’s health status and level of happiness. The first is associated with the features of social networks to which a person belongs, in which a link with a network is established through integrated relationships. This structural dimension encompasses the bases of individuals’ relationships, the size of relationship networks, intimate friends available, and frequency of contact. The second aspect of social support is the content of social relationships, which is associated with the functions of social support that involve the features of emotional support, such as love and empathy. In this respect, participatory and advisory support is associated with thinking and feelings, informational support focuses on problem solving and data collection, and instrumental support refers to assistance and services. The third aspect of social support is social network evaluation, which involves the measurement of the quantity and quality of support as well as satisfaction with social relationships [26]. Promoting such support can play a significant role in increasing individuals’ levels of happiness and satisfaction.

Similar to any other study, the present research has certain limitations, namely, the establishment of relationships with the elderly people, the acquisition of access to these individuals, and the lack of cooperation by some of them. The results of various studies have revealed that emotional support can exert the strongest impact on quality of life and happiness among the elderly. An equally important consideration, however, is that the elderly are also in dire need of services, financial assistance, and advisory support given their social, economic, and physical status. The findings highlight the need for increased social support to elderly people as this can elevate the levels of happiness in this age group. The amount and quality of support provided to elderly people by family and friends can serve as a predictor of level of happiness. Thus, society should provide the maximum social support (emotional, instrumental, informational, and appraisal) to this population so that certain conditions are accommodated for this target group to enable them to live a life replete with affection and kindness in their homes and more effectively alleviate their concerns regarding old age. Providing them sources of information and emotional support can similarly affect the lives of the elderly and contribute to the promotion of happiness and life satisfaction among them.
