This study is part of a school-based collaborative research project with a Nova Scotian Mi'kmaq community that hopes to shed light on the relationship between exposure to violence and mental health in First Nations youth. This particular study sought to examine how the multifaceted construct of resilience might act as a protective factor, buffering some students from the negative mental health consequences of exposure to violence. The present paper focuses on whether the construct of resilience, measured by the Child and Youth Resiliency Measure (CYRM; Ungar et al. 2008), has a moderating impact on the relationship between exposure to violence (emotional, physical, and sexual), measured by the Childhood Experience of Violence Questionnaire (CEVQ; Walsh, MacMillan, Trocme, Jamieson, & Boyle, in press), and posttraumatic stress symptoms, measured by the Child PTSD Symptom Scale (CPSS, Foa et al. 2001). Results showed that the positive relationship between exposure to violence--measured as emotional, physical, and sexual abuse, and witnessing domestic violence--and the reexperiencing symptom cluster of PTSD was moderated by resilience, such that exposure to violence was only predictive of reexperiencing at lower levels of resilience. These findings not only help provide further cross-cultural validation for the CYRM as a measure, but provide support for an ecological conceptualization of resilience.
