Sample characteristics
Across the full sample included in the evaluation (including recipients of SSI, SSDI, and neither at study enrollment), ages ranged from 18 to 60 years old (with a mean age of 40 years), and 58 percent of the sample was male. The sample was primarily White (64 percent) or Black (26 percent). About one-fifth of study participants (21 percent) did not have a high school diploma, whereas 37 percent had graduated high school (only), and 27 percent had at least some college. Before random assignment, on average, study participants had received SSDI benefits for 36 months and SSI benefits for 28 months. The average monthly benefit amount of SSDI and SSI received was $610 and $291, respectively. Finally, the most prevalent primary impairment in the sample was a mental impairment (42 percent).
