Considering that youth placed in rehabilitation centres have often experienced multiple traumatic events, and that specialized trauma-focused services are not routinely implemented in child protection services, a standardized assessment of traumatic events and symptoms should be put in place for this at-risk clientele. The purpose of this article is to provide an overview of psychometric measurement tools used to assess trauma in youth. This information is necessary in order to facilitate the development of a solid and cohesive mental health program that is focused on trauma in youth protection. Based on a systematic screening, 13 tools designed to collect information regarding traumatic events and symptoms were selected, most of which are youth self-reports. Practical and methodological considerations of these tools are presented. The implementation of a standardized assessment of trauma for children and youth in rehabilitation centres could serve as a catalyst for the development of specialized services for this particularly vulnerable and high needs clientele. The most promising trauma-focused interventions are discussed.
