Identity structure, narrative accounts, and commitment to a volunteer role

Degree of commitment was explored in relation to core self and role-identity. Thirty-one American emergency medical technicians (EMTs) described themselves in the EMT role (EMT now) and the way they anticipated they would be in the future (EMT future) by selecting items from an adjective checklist. Participants also described "real me," "ideal me," and "ought me." Ratings of commitment and extranormative activity were also obtained. Finally, participants described a positive and a negative episode they had experienced as an EMT in an open-ended question that was coded for task and relational content. Each participant's checklist data set was individually analyzed using HICLAS, a clustering algorithm for binary data (P. DeBoeck, S. Rosenberg, & I. Van Mechelen, 1993). Results indicate that the similarity between EMT now and real me best predicted activity and the similarity between EMT future and real me best predicted commitment (positive correlations in both cases). Older, more experienced EMTs tended to describe positive episodes in relational terms, whereas younger, less experienced EMTs described positive experiences in task-oriented terms.
