Overall, the retention of people with serious mental illness (SMI) in supportive housing is high. However, some supportive housing settings report average stays of only 15 months, and others report declines in housing retention over time. Many studies report variables associated with supportive housing stability and tenure, but there are few extensive, focused investigations on the subject. Hence, a literature review was conducted to investigate factors associated with supportive housing stability and tenure among people with SMI. The review of the included 28 papers reveals that the factors associated with supportive housing stability and tenure fell into two general categories of individual factors (including psychiatric factors and prior homelessness), and contextual factors (including program characteristics and sense of community and social support). In conclusion, further focus on contextual factors, as well as a potential reframing of individual factors as contextual, may be helpful in addressing issues related to supportive housing stability and tenure for people with SMI.

探索严重精神疾病患者的保障性住房使用期限和稳定性相关因素

总体而言，患有严重精神疾病 (SMI) 的人留在支持性住房中的比例很高。然而，一些支持性住房环境报告平均停留时间仅为 15 个月，而另一些则报告住房保留率随着时间的推移而下降。许多研究报告了与支持性住房稳定性和使用权相关的变量，但很少有针对该主题的广泛、集中的调查。因此，进行了文献综述以调查与 SMI 患者的支持性住房稳定性和使用权相关的因素。对纳入的 28 篇论文的审查表明，与支持性住房稳定性和使用权相关的因素分为两大类个人因素（包括精神因素和以前的无家可归），和背景因素（包括项目特征以及社区和社会支持感）。总之，进一步关注背景因素，以及将个人因素重新定义为背景的潜在因素，可能有助于解决与 SMI 患者的支持性住房稳定性和使用权相关的问题。
