This study examined several hypotheses for matching patients to 12-Step and
cognitive-behavioral (CB) treatments in a multisite evaluation of VA inpat
ient substance abuse programs. A total of 804 male patients in five 12-Step
programs, and 1069 male patients in five CB programs completed an intake,
discharge, end 1-year follow-up questionnaire, The findings did not support
the notion that certain patient characteristics would differentially predi
ct better outcomes after 12-Step and CB treatment. This conclusion held whe
n the pure est 12-Step and CB programs were used, and when patients who rec
eived the full dose of treatment (i.e., treatment completers) were examined
separately. Process analyses of the hypothesized mechanisms underlying the
patient-treatment matching effects did not yield the expected links among
patient characteristics, proximal outcomes, and 1-year outcomes. Our conclu
sion is that there is no advantage to matching men with substance abuse pro
blems to 12-Step or CB treatments based on the patient attributes measured
here.
