In a study of social identity in everyday social interaction, 133 undergraduates described their social interactions for two weeks using a variant of the Rochester Interaction Record. Some participants were members of campus social organizations and some were not, and descriptions of interactions included the social affiliation (identity) of the others who were present. Participants also completed measures of social dominance and self-construal. A series of multilevel random coefficient modeling analyses found that for members of social organizations, on average, the presence of members was not associated with a change in reactions to interactions; however, for members high in social dominance, interactions with members were more positive than interactions with non-members. In contrast, for non-members, the presence of a member was associated with less positive interactions on average; however, there were no such differences for non-members who were high in independent self-construal.
