Depression is one of the most prevalent psychiatric diseases and significantly negatively impacts patients’ productivity, quality of life, and cognitive functions... By examining scientific collaboration, this article also identified hot topics in depression research, which represent the areas of focus that numerous researchers have decided to have substantial potential to prevent and cure this pervasive disease... The analysis of centrality revealed that Harvard University has the highest degree and betweenness centrality and the lowest closeness centrality... The betweeness centrality of the University of Toronto in Canada was third highest and the closeness centrality second highest, but its degree centrality did not appear in the top 10... It also indicated that the University of Toronto had access to lots of research resources and was closely connected to core institutions, but lacked robust communications with other institutions... Similarly, Kings College London in England had a high betweenness and closeness centrality, indicating that it maintained an important position in the network, but its degree centrality did not make the top 10... However, some countries, such as France, had many ties but not many papers, while others, such as Brazil, had many papers but few ties... Finally, we found that the three countries that engaged in international collaboration most frequently – USA, England, and Germany – also have the most number of publications... Using the cluster term and research direction, we identified seven research hotspots... The first research hotspot, diagnosis and assessment, was found in sub-network 0, 2, 3, 8, 9, 12, 13, 14, 15, 16, 19, 20, 25 and 26... Due to the complexity of this disease and the diversity of the patients that it affects, scientific collaboration plays an indispensable role in understanding and treating depression... Thus, this article used SNA to construct and analyze the structure of scientific collaboration in depression research at the levels of authors, institutions, and countries from 2003 to 2012... The neurotransmitters responsible for emotion and mental state, mainly 5-hydroxytryptamine, dopamine, and catecholamine caused insanity when their processes of composition, storage, release, and receptor binding were disrupted... This study laid the foundation for psychopharmacology, leading to neurotransmitters research that has guided the development of new generation psychotropic drugs... Further, identifying research focus within the field can help researchers navigate the forefront of depression research.

Figure 3: Distribution of papers about countries’ collaboration.

Mentions: From 2003 to 2012, a total of 176 countries were represented. The number of papers with international collaborations increased from 5168 in 2003 to 12,750 in 2012 [Figure 3]. The most productive countries were USA, England, and Germany; approximately 53% of all papers in depression research originated in the USA. China was in 10th place, producing 4586 papers [Figure 4].
