Abstract: Crisis intervention in psychiatric nursing plays a pivotal role in stabilizing individuals experiencing acute psychological distress, often at the edge of mental breakdowns. Acute psychiatric settings demand rapid, compassionate, and effective responses to prevent escalation and promote safety. Over the years, several crisis intervention models have emerged to guide healthcare professionals in managing psychiatric emergencies. This review explores key theoretical models—including the Roberts’ Seven-Stage Crisis Intervention Model, the SAFER-R Model, and the ABC Model of Crisis Intervention—alongside their application in acute care environments. The article critically evaluates the effectiveness, ethical implications, and limitations of these models, particularly when applied to diverse populations and high-risk psychiatric cases. It concludes with recommendations for integrating culturally competent, trauma-informed, and recovery-oriented approaches in crisis intervention practice. The review underscores the need for ongoing training, interdisciplinary collaboration, and research in shaping the future of mental health crisis care.
