This report presents the short-term outcomes of the families enrolled in the Family Options Study, funded by the U.S. Department of Housing and Urban Development and carried out by Abt Global. The study is a multi-site random assignment experiment designed to study the impact of various housing and services interventions on homeless families. The report documents how families are faring approximately 20 months after random assignment to one of four interventions: community-based rapid re-housing(CBRR), project-based transitional housing (PBTH), permanent housing subsidy (SUB), and usual care (UC). Outcome measures fall within five domains: housing stability; family preservation; adult well-being; child well-being; and self-sufficiency. The collection of extensive cost data for each of the interventions tested enables the calculation of the costs that can be tied to each of the interventions, and in turn, used to understand the cost of achieving the outcomes observed. The study resulted in strong and significant findings, particularly related to the power of offering a voucher to a homeless family.
