This Chapter Describes The Rationale, Initial Specification, And Testing Of Cti In Two Randomized Trials With Unhoused Men And Women Following Discharge From Institutional Settings In New York. Through Our Decade Of Work In The Nascent Homelessness Services Sector, We Observed That While Considerable Attention Had So Far Rightfully Focused On Designing Innovative Outreach Approaches Intended To Successfully Engage Homeless Persons On The Streets And Shelters, Few Focused Systematically On The Transition To Community Care. While Engagement And Treatment Programs Must Effectively Build Close, Trusting Relationships With Clients, This Often Leads To Clients Depending On Program Staff To Meet A Wide Range Of Needs. In Contrast, The Transition Process Must Help Clients Move Toward Greater Autonomy And Reliance On Other Sources Of Support In The Community. This Underdeveloped Stage Of Service Delivery Became The Focus Of The New Cti Model-- Provided By Publisher.
