Application of social identity theory in group therapy with stigmatized adults.

Social identity theory was applied in group therapy for adults with mild mental retardation. Social identity theory suggests that social group membership, also called collective identity, has an impact on self-esteem. Individuals will try to maintain self-esteem by viewing their social groups positively. This may not be possible for individuals who are members of a stigmatized group. However, it may be possible to enhance self-esteem by broadening one's awareness of collective identity. Furthermore, being able to positively view other individuals who are co-members of one's own stigmatized group can also have positive consequences for self-esteem. A clinical vignette demonstrates this process in group therapy. Results are discussed as being applicable to members of various stigmatized groups.
