Notes: DATCAP refers to the Drug Abuse Treatment Cost Analysis Program. All costs are inflated to 2006 dollars.
N/A = not available. Some numbers may not add, divide, or multiply exactly due to rounding.
Table includes data from Fleming, Mundt, French, Manwell, Stauffacher, & Lawton Barry (2000); French, Zavala, McCollister, Waldron, Turner, & Ozechowski (in press); Knealing, Roebuck, Wong, and Silverman (in press); Kunz, French, and Bazargan-Hejazi (2004); Mundt, French, Roebuck, Baier Manwell, and Lawton Barry (2005); Roebuck et al. (2003); Zavala et al. (2005) and numerous unpublished DATCAP studies.
Weekly Economic Cost per Client = Total Annual Economic Cost ÷ Average Daily Census ÷ 52.14 weeks
Economic Cost per Treatment Episode = Weekly Economic Cost per Client × Average Length of Stay (weeks)
We conducted extensive searches of the relevant literature on screening and brief intervention and the results of only these three studies provided the information necessary to be included in the table and subsequent analyses. Furthermore, as the DATCAP was not originally designed to evaluate costs of screening and brief interventions, Fleming et al. (2000) do not directly use the DATCAP, but a similar method to estimate the cost of their intervention.
Reported costs for in-prison therapeutic communities are incremental (i.e., in addition to standard incarceration).
