[Application of Trauma-Informed Care in a Patient With Schizophrenia and Childhood Trauma]

This article presents a case study on the application of trauma-informed care on a male patient with schizophrenia and a history of childhood trauma. The nursing process was designed using the Substance Abuse and Mental Health Services Administration framework. For this case study, the "4R" core assumptions were transposed into five actionable principles (safety, trustworthiness, collaboration, empowerment, and choice), which guided all of the provided interventions. From July 14 to August 7, 2025, the nursing care focused on promoting psychological and emotional safety, facilitating the co-regulation of trauma responses, and fostering the development of personalized emotional coping strategies. All of the key outcome measures demonstrated significant improvement, with the patient showing a marked decrease in aggressive behaviors, the development of the ability to identify and articulate trauma triggers, and the ability to successfully use at least three distinct grounding techniques for emotional stabilization. This case confirms that applying trauma-informed care theory in a structured manner can effectively improve patient self-efficacy and strengthen the nurse-patient collaborative relationship. The findings provide a valuable, evidence-informed care model for managing the complexities of co-occurring psychiatric symptoms and trauma.
