Measures self-esteem derived from one's memberships in social groups, based on Tajfel & Turner's Social Identity Theory. Membership Esteem captures how good a member of social groups one perceives oneself to be. Private Collective Self-Esteem captures personal evaluation of one's social groups (whether one thinks positively of them privately). Public Collective Self-Esteem captures perceptions of how outsiders evaluate one's social groups. Importance to Identity captures how central group memberships are to one's self-concept. Collective self-esteem is a key moderator of intergroup behaviour — high collective self-esteem predicts stronger in-group favouritism, resistance to threats to group identity, and group-based consumption behaviours. Widely relevant to brand community research, nationality-based consumer ethnocentrism, and group identity in inclusive advertising contexts.
