Demonstration (Evaluation report) | Evaluation design | Intervention description | Target population/sample | Summary of findings |
---|---|---|---|---|
Ticket to Work (TTW) (Stapleton et al. 2008) | Non-experimental evaluation initiated in three stages across the US from 2002 through 2004; researchers can use the variation in the phased rollout to evaluate impacts on service use, earnings, and benefit receipt. | Tickets (vouchers) to select from SSA-approved public and private providers. Providers can decide whether to accept tickets, and beneficiaries can work with providers to determine the types of services needed. | Tickets were mailed to most SSDI and SSI beneficiaries. | Impact estimates from early stages of the rollout for earnings and benefit amounts were too small to differentiate from historical variation in these outcomes. |
Benefit Offset Pilot Demonstration (BOPD) (Weathers and Hemmeter 2011) | Random assignment demonstration implemented in 2005 in four demonstration states. | Intervention included a gradual income benefit offset of $2 to $1 for SSDI beneficiaries earning above SGA. | Included SSDI beneficiaries who did not receive SSI. | No aggregate employment or earnings impacts. BOPD had mixed effects on earnings depending on whether the volunteer earned above or below SGA. |

Mental Health Treatment Study (MHTS) (Frey et al. 2011) | Random assignment demonstration in 23 projects in sites throughout the country implemented from 2006 through 2010. | Intervention included supported employment and systematic medication management services over a 24-month period. | Included 2,238 SSDI beneficiaries with a primary impairment of schizophrenia or affective disorder. | Percent employed (24 months) |

Average earnings (past month earnings averaged over eight interviews) | ||||
Control: $97 | ||||
Treatment: $148 | ||||
Youth Transition Demonstration (YTD) (Fraker 2013) | Random assignment demonstration implemented between 2003 and 2008 in six US sites. | Intervention varied according to site but included services such as job coaching, employment supports, and benefits counseling. | Included approximately 880 youth ages 14 to 25 per site who receive SSA disability benefits or who are at risk of receiving such benefits after leaving school. | Percent employed ranged across sites from no impact to high impact (West Virginia) |
