Critical Time Intervention

Critical Time Intervention (CTI) is an empirically supported case management model that prevents homelessness and fosters recovery among vulnerable people during periods of significant transition. Individuals transitioning from institutions, such as jails, hospitals, and shelters, to the community often have trouble re-establishing connections to crucial supports. CTI is a time-limited case management approach that aims to build enduring connections to supports during transitional periods. Originally developed over 20 years ago, CTI has since been subjected to numerous tests of its impact, including several randomized trials. CTI is now widely used in homelessness services systems, and interest continues to grow in how the model might be effectively applied in other social service and health sectors. This chapter describes core components of the original CTI model and an overview of its adaptation for use in Rapid Re-Housing programs.
