Ouimette PC, Finney JW, Gima K, Moos RH. A comparative evaluation of substance abuse treatment III. Examining mechanisms underlying patient-treatment matching hypotheses for 12-step and cognitive-behavioral treatments for substance abuse. Alcoholism, clinical and experimental research. 1999 Mar 1; 23(3):545-51.
This study examined several hypotheses for matching patients to 12-Step and cognitive-behavioral (CB) treatments in a multisite evaluation of VA inpatient 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, and 1-year follow-up questionnaire. The findings did not support the notion that certain patient characteristics would differentially predict better outcomes after 12-Step and CB treatment This conclusion held when the purest 12-Step and CB programs were used, and when patients who received 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 conclusion is that there is no advantage to matching men with substance abuse problems to 12-Step or CB treatments based on the patient attributes measured here.
