Reliability and Validity of the VI-SPDAT

The Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT) is being used to allocate scarce housing services to individuals in need of housing. The goal of this study was to determine the measurement properties, including reliability and validity of the VI-SPDAT using Homeless Management Information System (HMIS) data. Study findings are reported in full here, and a blog post on the study can be found on the Homeless Hub.
