aOne SNI subscale (Number of People in Social Network) measures the total number of regular contacts that a person maintains, reflecting overall network size. A second subscale (Number of Embedded Networks) measured the number of different groups these contacts belong to, reflecting network complexity...
several of our measures are commonly used to assess traits related to autism spectrum disorder (e.g. Empathizing Quotient13, Systematizing Quotient14, and Social Responsiveness Scale15), the social network index has been widely used as a proxy for social connectedness in real life, and the 16PF...
These responses are then summed to construct a social isolation score, such as the Social Network Index (SNI, the most frequent measure seen in the literature), the Social Isolation Index, the Social Isolation Scale, the Social Integration Index, and the Social Isolation Score, among others (...
