Identity Fusion in US Military Members

Identity fusion, the visceral sense of interconnectedness between oneself and the members of a group, has been associated with military service anecdotally and examined among foreign military groups. However, no study to date has explored fusion and its relationship with functioning among U.S. military members. The aims of this study were (1) to examine the incremental predictive validity of fusion, (2) to examine the relationship between fusion and pro- and antisocial in-group behaviors, and (3) to determine how one's attitude toward their military service may affect fusion. Data were collected via self-report using Amazon's Mechanical Turk software. Results indicated that fusion predicted progroup beliefs and in-group helping behaviors above and beyond other indicators of military identity. Further, satisfaction with the military mediated the relationship between fusion and willingness to give time to other veterans. Identifying an important mediator of fusion expands upon earlier work in the field and suggests routes for future inquiry.
