A Triage Tool for assessing vulnerable transition age youth (TAY) age 18-24 was developed by Dr. Rice, in conjunction with Corporation for Supportive Housing (CSH). The tool was developed in consultation with providers of permanent supportive housing (PSH) to youth, consultation with stake holders from youth systems of care, and site visits with six providers of permanent supportive housing to youth, that at the time of this report, operate approximately 75% of the total PSH units available for TAY in LA County. Data from Rice’s NIMH-funded survey of approximately 700 homeless youth, recruited from drop-in centers in the Los Angeles communities of Hollywood, Santa Monica, and Venice, from 2011 to 2012 was used to conduct the subsequent analyses.
