An Identity Theory Approach to Commitment

Commitment highlights one of the ways in which individuals infuse roles and social structure with self-motivated behaviors, thereby linking the self to social structure. Past theoretical formulations of commitment, including work by Becker, Stryker, and Kanter, tended to focus on commitment as a tie between an individual and either 1) a line of activity, 2) particular role partners, or 3) an organization. An approach based on identity theory or affect control theory (each of which uses a cybernetic model of identity processes) suggests that commitment connects an individual to an identity. In this view, commitment does not link a person to consistent lines of activity, other role partners, or organizations, but to a stable set of self-meanings. These stable self-meanings, in turn, produce consistent lines of activities. This idea is borne out in an analysis of data from the college student role, in which there exist multiple, independent bases of commitment containing cognitive and socioemotional components. Commitment moderates the relationship between student identity and role performance such that the relationship is stronger for persons with higher commitment.
