Abstract

ABSTRACT This study examined the reliability and validity of the Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT), a widely-used assessment of the health and social vulnerabilities and housing needs of individuals experiencing homelessness. Homeless Management Information System data were obtained for 1495 individuals who were administered the VI-SPDAT between 2014 and 2016. Subsamples were selected for reliability and validity assessments. Results suggest there are challenges to the reliability and validity of the VI-SPDAT in practical use. VI-SPDAT total scores did not significantly predict risk of return to homeless services, while type of housing was a significant predictor. Vulnerability assessment instruments have important implications for communities working to end homelessness by facilitating prioritization of scarce housing resources. Findings suggest that further testing and development of the VI-SPDAT is necessary.

漏洞指数服务优先级决策辅助工具（VI-SPDAT）在实际实施中的可靠性和有效性

摘要本研究检验了脆弱性指数服务优先级决策援助工具（VI-SPDAT）的可靠性和有效性，该工具是一种广泛使用的评估无家可归者的健康和社会脆弱性以及住房需求的工具。获得了1495名2014年至2016年间接受VI-SPDAT治疗的无家可归者管理信息系统数据。选择子样本进行可靠性和有效性评估。结果表明，VI-SPDAT在实际使用中的可靠性和有效性存在挑战。VI-SPDAT总分不能显著预测重返无家可归者服务的风险，而住房类型是一个显著的预测因素。脆弱性评估工具对致力于通过促进稀缺住房资源的优先次序来结束无家可归现象的社区具有重要影响。研究结果表明，VI-SPDAT的进一步测试和开发是必要的。
