When reintegration fails: Stigmatization drives the ongoing violence of ex‐combatants in Eastern Democratic Republic of the Congo

Reintegration of ex‐combatants involves multiple challenges. In addition to the trauma‐related psychological sequelae, social obstacles in the community can aggravate psychopathological aggressive tendencies and lead to the continuation of violence in civilian life. However, the association between others’ negative attitudes and ex‐combatants’ ongoing perpetration of violence remains largely unexplored. Between September 2018 and May 2019, we assessed a representative community sample of adults in Eastern DR Congo ( N  = 1,058) and measured trauma exposure, perpetration, mental health problems (PTSD, depression, and appetitive aggression), perceived stigma (shame, perceived lack of social acknowledgement), experienced stigma, and skepticism toward reintegration with ex‐combatants. Male ex‐combatants (12%, n  = 129) had more past trauma and violence perpetration than other community members and a greater number of recent conflicts (including both victimization and perpetration) within the community and with strangers/organized violence. They reported more experienced stigma, more severe PTSD symptoms but were less skeptical about reintegration. Ex‐combatants’ ongoing violence was predicted by an interplay of the community's skepticism toward reintegration and ex‐combatants’ perceived and recently experienced stigma (often attributed to the armed group history) and mental health problems, in addition to lifetime traumatization. These findings promote the need for combined interventions that address individual mental health problems including aggression and collective discriminatory attitudes and behaviors.
