    Document: The second most common document type was meeting abstracts (41 documents, 4.28% of the total). As expected, the majority of the publications were written in English (99.06%). Figure 1 shows the publication productivity related to social media and the publication productivity related to social media in psychology over time. The correlation analysis clearly shows a high correlation between the number of publication in the field of social media and the publication productivity related to social media in psychology (r = 0.995; p value < 0.001). This increase in publications related to social media in psychology seems to be related to (1) social networking sites, which became very popular in previous decade [25, 26] ; (2) increasing interest in this field in multiple health disciplines [27] [28] [29] [30] [31] ; (3) or general cause such as the increasingly prevalent use of the internet, which has allowed more rapid distribution of medical knowledge through scientific research [32] . Table 1 shows information about the 10 countries with the most published papers. The USA is responsible for the most papers (548 documents, 57.14% of the total), with the highest h-index values (h-index value = 48). The USA is followed by the UK (69, 6.69%), Canada (46, 4.80%), Germany (46, 4.80%), and Australia (44, 4.59%). The h-index for all retrieved publications was 59. The publications with the most international collaboration were those from the USA (n = 100). The UK and China ranked second and third, with 35 and 17 documents for each, respectively. The collaboration between countries based on co-authorship is shown in Fig. 2 . The USA is the most networked country, collaborating with 26 countries, followed by the UK (n = 22) and Germany (n = 15). The USA was the most prolific country in producing publications related to psychology in social media, contributing to more than of half of the publications related to this topic. This research output from the USA is possibly due to the large size of the population or economic forces [33, 34] . Furthermore, most of the social networking sites were established and founded in the USA. These findings are similar to those found in previous bibliometric studies in different fields, principally that the USA had the highest activity in scientific research output worldwide and in international collaboration networks, as well as the highest h-index [32, [35] [36] [37] . Regarding the international collaboration, this emphasizes the significance of global networking and its impact on research output [38] [39] [40] [41] . Table 2 lists the top 10 most productive journals with their IF. The major publication outlets for research related to social media in psychology include The scientific landscape of main research areas related to social media in psychology is presented in Fig. 3 , based on the retrieved publications terms co-occurrence network from the retrieved publications. The most important research areas related to social media in psychology were personality psychology, experimental psychology, psychological risk factors, and developmental psychology. Based on the map, the four main clusters (denoted by the green, blue, red, and yellow colours) were characterised by the most commonly used terms in the research related to social media in the psychology field. Green coloured cluster represented terms related to the developmental psychology topic, such as "child", "adolescent", or "adult"; blue coloured cluster represen
