A benefit-cost analysis of full continuum (FC) and partial continuum (PC) care was conducted on a sample of substance abusers from the State of Washington. Economic benefits were derived from client self-reported information at treatment entry and at 9 months postadmission using an augmented version of the Addiction Severity Index (ASI). Average (i.e., per client) economic benefits of treatment from baseline to follow-up for both FC and PC were statistically significant for most variables and in the aggregate. The overall difference in average economic benefit between FC and PC was positive ($8,053) and statistically significant, favoring FC over PC. The average cost of treatment amounted to $2,530 for FC and $1,138 for PC (p < .01). Average net benefits were estimated to be $17,833 (9.70) for FC and $11,173 (23.33) for PC, with values showing statistical significance (p < .05). Results strongly indicate that both treatment options generated positive and significant net benefits to society.
