Table 3 Quality-of-life (QoL) scores and cost per QoL point in the four domains at the 6-month assessment ( n = 285)

	Baseline score	6-month score	QoL gained	Cost per QoL point
	M( SD)	M( SD)
Physical	58.53(15.51)	60.13(14.68)	1.6	368.7
Psychological	49.89(16.64)	53.19(17.15)	3.3^**	178.7

Environmental	52.92(16.97)	55.42(16.20)	2.5^**	235.9

Note. Repeated measures analyses of variance of baseline and 6-month follow-up were performed to control for age, education, gender, age at first heroin use, methadone dose and days in MMT before study. Cost per QoL point = Total MMT cost/Incremental QoL gain. MMT cost was $1179.70 in 2009. For the 6-month calculation, $589.85 (1179.7/2) was used.
