AI Article Synopsis
- Homophily is the tendency for individuals to associate with others who are similar in attributes like sex, ethnicity, and social class, which has been well-documented in social network research.
- Existing studies typically examine these dimensions separately, but people possess multiple attributes simultaneously and belong to various social groups.
- Analyzing eleven adolescent friendship networks, the study finds that while having common attributes generally strengthens friendship ties, the impact diminishes when too many similarities are present, suggesting the need for more nuanced research on multidimensional homophily.
Article Abstract
Homophily - the tendency for individuals to associate with similar others - is one of the most persistent findings in social network analysis. Its importance is established along the lines of a multitude of sociologically relevant dimensions, e.g. sex, ethnicity and social class. Existing research, however, mostly focuses on one dimension at a time. But people are inherently multidimensional, have many attributes and are members of multiple groups. In this article, we explore such multidimensionality further in the context of network dynamics. Are friendship ties increasingly likely to emerge and persist when individuals have an increasing number of attributes in common? We analyze eleven friendship networks of adolescents, draw on stochastic actor-oriented network models and focus on the interaction of established homophily effects. Our results indicate that main effects for homophily on various dimensions are positive. At the same time, the interaction of these homophily effects is negative. There seems to be a diminishing effect for having more than one attribute in common. We conclude that studies of homophily and friendship formation need to address such multidimensionality further.

Background: A global-scale pandemic, such as the COVID-19 pandemic, greatly impacted communities of color. Moreover, physical distancing recommendations during the height of the COVID-19 pandemic negatively affected people's sense of social connection, especially among young individuals. More research is needed on the use of social media and communication about depression, with a specific focus on young Black Americans.

Few studies examined the social network structures within multicultural volunteer programs for low-income diverse older adults, making it unclear how diverse older adults establish social connections beyond their co-ethnic community. This study aims to identify the social network structures within a Senior Companion Program (SCP), a multicultural low-income volunteer program in a Midwestern Metropolitan area in the United States. Data were collected through surveys during a SCP monthly in-service training in October 2021.

Background: Peer influence on risky behavior is particularly potent in adolescence and varies by gender. Smoking prevention programs focused on peer-group leaders have shown great promise, and a social influence model has proven effective in understanding adult smoking networks but has not been applied to adolescent vaping until 2023. This work aims to apply a social influence model to analyze vaping by gender in a high school network.

Relationships between humans are essential for how we see the world. Using fMRI, we explored the neural basis of homophily, a sociological concept that describes the tendency to bond with similar others. Our comparison of brain activity between sisters, friends and acquaintances while they watched a movie, indicate that sisters' brain activity is more similar than that of friends and friends' activity is more similar than that of acquaintances.

Adolescents who befriend online game using peers may be at risk for initiated and continued excessive game use (online gaming use homophily). The present article examined how adolescents' severity of online gaming use related to their friends' online gaming behavior bi-directionally across a semester (peer selection or peer influence effect). Students from two universities completed three waves of online surveys within four and a half months (N = 3079; 33.
