Note. “Other” includes programmatic discharges beyond the control of the inmate, including institutional transfer,
writ or court order, medical discharge, etc. “Direct Parole” indicates inmates who received parole as the reason for
their treatment program discharge. In other words, such inmates were paroled directly fiom their treatment
program. These figures are unrelated to the number of inmates who may eventually apply for (or receive) parole at
a later date following completion of their substance abuse programs.
As expected, the experimental and comparison groups differed considerably on total
treatment exposure (Table 5). Treatment exposure was calculated for each inmate in the sample
by multiplying the number of weeks he spent in each treatment program by the program’s
intensity (number of hours of treatment programming per week). TC inmates in general had more
than 10 times as much total treatment exposure as inmates in the Education or Outpatient groups,
thus providing a strong rationale for the formation of comparison groups. Total treatment
exposure can also be entered as a control variable in multivariate analyses, although care needs to
be exercised since program type is highly associated with treatment exposure.

As noted earlier, successfbl and unsuccesshl discharges were analyzed separately in outcome
analyses in order to help address shortcomings of previous evaluation studies.
