This document discusses crisis, crisis intervention, and the stages of crisis development. It defines a crisis as a sudden event that disrupts homeostasis and normal coping mechanisms. A crisis involves heightened anxiety, acute symptoms, and potential for growth or deterioration. The stages of crisis include impact, recoil, and post-traumatic periods. Crisis intervention aims to resolve the immediate crisis and restore pre-crisis functioning through assessment, planning interventions, and implementing reality-oriented support.
