Other researchers at the time tended to blur the distinction. Pearlin (1985) included three aspects of social
support: (a) social networks (i.e., everyone with whom the individual has contact), (b) group affiliation (i.e., those
with whom the individual has an attachment), and (c) interpersonal interaction (i.e., active affiliations involving
trust and intimacy). House and Kahn (1985) referred to (a) social networks (i.e., the structures that exist among
a set of relationships), (b) social support (i.e., the functional content of interactions including emotional concern,
instrumentality, and information), and (c) social integration. Cobb (1976) defined support to include, variously,
emotional support, information that leads one to believe he or she is valued, and a feeling that he or she
belongs to a network of communication and mutual obligation.
