Social network analysis in social psychological ressearch (1990-2020): A scoping review.

Over the last two decades, Social Network Analysis (SNA) has become a standard tool in various social science disciplines. In social psychology, however, the use of SNA methodology remains scarce. This research identifies gaps in SNA use in Social Psychology and offers pathways for its further development. It reviews all empirical papers using SNA published in high-ranking social psychology journals over the last three decades. Findings reveal that SNA has been used across striking diversity of fields and subdomains central to the discipline, confirming its relevance for any field in Social Psychology in which the role of interpersonal or intergroup relationships is central to understand psychological and behavioural outcomes. However, the use of SNA in Social Psychology has been mostly limited to non-experimental and non-longitudinal studies, using student samples and with a focus on basic measurements of network structures such as density and centrality. The contributions of SNA to the understanding of psychosocial mechanisms have therefore remained modest. We propose several strategies by which such gaps can be filled in future research and the full potential of SNA for social psychology realized.
