Trauma-informed practices make a conscious effort to understand the deep, personal impact trauma has on individuals. These practices seek to avoid re-traumatization by empowering individuals in:

  • Decision making
  • Creating safety and trust
  • Choice and collaboration
  • Building skills in personal problem solving

The article under discussion reviewed four quantitative studies that had an emphasis on trauma-informed therapy in which an assessment for suicide and self harm was a component. The results of the review indicated that only two of the studies reported improvements in suicidal ideation, intent, and behavior. As a result, conclusions about the effectiveness of trauma-informed therapies are difficult to determine. While the work of trauma-informed therapies is still in its infancy, more qualitative and quantitative research is needed to develop a body of evidence. Identifying ways, including those considered non-traditional, to successfully treat Veterans who have experienced trauma and suicidal ideation will enhance all available treatment options.
