"Trauma Informed Care" is defined as "care that is grounded in and directed by a thorough understanding of the neurological, biological, psychological, and social effects of trauma and violence on humans and is informed by knowledge of the prevalence of these experiences in persons who receive mental health services." Roberts' Seven-Stage Crisis Intervention Model consists of a biopsychosocial and lethality assessment, establishment of rapport, the identification of problem dimensions, dealing with feelings, exploring alternative coping methods, formulation of an action plan, and provision of a follow-up plan. Each sequential stage of crisis intervention is examined. The outcomes demonstrated in the two case studies are goal setting and goal attainment, the discovery of new coping skills, the implementation of an action plan, crisis stabilization and resolution, and reduction in psychological symptoms. The chapter emphasizes the importance of evidence-based practice, which is defined as "the use of treatments for which there is sufficiently persuasive evidence to support the effective care and management of individuals using the best evidence in obtaining the desired outcomes." At times when there is not sufficient evidence to develop a treatment approach in a particular case, the treatment team must develop its own evidence-based search in order to inform the care provided. The search for an appropriate evidence-based treatment should focus on the client or problem of interest, the intervention being considered, the inclusion of a comparison group, and the outcome of interest. 17 references
