Objectives: This study investigates the application of Trauma-Informed Care (TIC) for military veterans, particularly those with trauma-related experiences, emphasizing conflict management and therapeutic communication. It focuses on addressing the unique needs of adolescent and older veterans to improve mental health outcomes and facilitate smoother transitions to civilian life. Method: The research examines TIC’s effectiveness in enhancing veterans' emotional regulation, collaborative problem-solving, and interpersonal conflict management skills. It emphasizes therapeutic communication techniques such as active listening and reflective statements to foster trust and support veterans in exploring their emotions safely. Results: TIC helps adolescent veterans, who often struggle with emotional expression, and older veterans, who may have repressed emotions over time, in managing conflicts and understanding their trauma. Therapeutic communication under TIC builds trust between veterans and healthcare providers, facilitating open emotional expression. However, barriers, including limited TIC training for healthcare providers, rigid care structures, and organizational constraints, impede effective implementation. Discussion: While TIC provides a promising framework for supporting veterans, its success relies on overcoming institutional challenges. Expanding training, restructuring healthcare models, and fostering an organizational culture that prioritizes trauma-sensitive care are critical steps to fully integrating TIC. Addressing these challenges could significantly improve mental health outcomes for adolescent and older veterans, promoting resilience and facilitating successful reintegration into civilian life.
