The Interventions We’ve Identified Are Linked Below

Those found through an expert review process to meet the Congressional “Top Tier” evidence standard are denoted “Top Tier”; those found to require only one more step to meet this standard – e.g., replication of their sizeable, sustained effects in an additional well-conducted randomized controlled trial – are denoted “Near Top Tier”. The other listed interventions have been found promising by Coalition staff but have not yet been identified by the expert panel as Top Tier or Near Top Tier – in some cases, because of study limitations (such as only short-term follow-up) that indicate the need for additional testing.1

Top Tier Critical Time Intervention (A case management program to prevent recurrent homelessness in people with severe mental illness): Randomized controlled trials show a sizable decrease in rates and duration of homelessness.

1 While we strive to ensure that our staff-level summaries are accurate and balanced, readers should note that they have received less scrutiny than those reviewed by the expert panel for Top Tier or Near Top Tier consideration.
