CTI Model

CTI Model

Critical Time Intervention (CTI) is a time-limited evidence-based practice that mobilizes support for society’s most vulnerable individuals during periods of transition. It facilitates community integration and continuity of care by ensuring that a person has enduring ties to their community and support systems during these critical periods. CTI has been applied with veterans, people with mental illness, people who have been homeless or in prison, and many other groups. The model has been widely used on four continents.
