Dyadic (Relational) Cohesion


Cohesion is generally thought of as a group-level property, reflecting the connectedness of the group network. However, it is convenient to also think of dyadic-level cohesion, which reflects the strength or closeness of a pair of nodes. In older network literature, dyadic cohesion referred to as "relational cohesion" or as "social proximity".
