Sensitivity analysis of intervention costs plus societal costs over four years

Economic Outcomes	OM-plus-RMC (N=219)	OM-only (N=217)
Physical and Mental Health Services	$11,637 (24,882)	$12,711 (22,153)
Social Services	$2,224 (5,477)	$2,460 (3,548)
Criminal Activity	$21,078 (82,619)	$19,438 (59,291)
Criminal Justice System Involvement	$2,739 (5,010)	$2,493 (4,644)
Treatment of Substance Use Disorders	$4,380 (4,927)	$3,765 (4,435)
Employment Earnings	(−) $17,556 (29,133)	(−) $14,238 (21,546)
Direct Intervention Costs	$4,889 (52.56)	$2,705 (23.84)
Total Societal Costs – criminal activity	$26,652 (97,981)	$26,750 (73,097)
Difference in total societal costs OM-plus-RMC minus OM-only	(−)$98 (122,243)
Total Societal Costs – criminal justice system	$8,300 (44,041)	$9,971 (36,118)
Difference in total societal costs OM-plus-RMC minus OM-only	(−)$1,671 (57,097)

Notes: Costs reported in 2007 dollars. Total costs include direct intervention costs plus societal costs (minus employment earnings). Total societal costs were calculated two ways: first, using self-reported criminal activity for which the monetary conversion factors already include criminal justice system costs, and second, using criminal justice system costs only. Standard deviations in parentheses. Incremental differences may not be exact due to rounding errors.
