Nowadays Social networks are an important part of our lives (
1) and are considered as a new way of communicating in daily life (
2). Besides the growing number of the elderly in Iran (
3), we are witnessing the development of social media such as Facebook, Instagram, Telegram, Viber, with usability through cellphones. Today’s, individuals aged 50 or over use online social media as a part of their daily life to expand their social relationships (
4). The role of social networks and its positive impact on quality of life (
5) and subjective well-being (
6) has been confirmed. Furthermore, evidence shows the various benefits of seniors’ use of technology and online social networks such as reduce loneliness (
7,
8), depression,stress, and increase life satisfaction (
9,
10) as well as establishing an intergenerational relationship of senior members of a family with younger members (children and grandchildren) (
11). Another advantage is to reduce isolation through engagement in social interactions (
12). However, there are various reasons for social networks not to be used by older adults. Old people do not recognize the value of using online networks, neither do they have the skills to use such technology (
13). In another study, various personal reasons (such as functional capabilities), technology-based problems (such as cost and complexity of use), and environmental barriers were among the other reasons introduced for not using social networks by older adults (
14).
Given the benefits of using these types of networks, it is necessary to examine the barriers and problems that seniors may encounter when using the social networks. Identifying these difficulties and exploring the challenge experienced by the older generation in surfing social networks can help policy-makers facilitate the sue of such media. Given the existing research gap in Iran, we aim to understand the difficulties encountered by older adults when using online social networks.
