The 5-factor client-report Dimensions of Change in Therapeutic Communities Treatment Instrument-Adolescent (DCI-A) was developed to assess adolescent substance abuse treatment process in the therapeutic community (TC). The goal of this study was to use bifactor modeling to derive a unidimensional DCI-A short-form (DCI-A-SF) that would represent content from the original DCI-A factors. Data are from 442 adolescents receiving treatment at one of seven residential TC programs. Bifactor analyses suggested selection of seven DCI-A items to comprise the short form. Three items are from the treatment motivation factor, and one item was selected from each of the remaining four factors. Confirmatory factor analysis suggested that the 7-item DCI-A-SF is strongly unidimensional, and unidimensional IRT analysis of the items indicated good internal consistency. A structural equation model that demonstrates the mediating relationship of DCI-A-SF with other measures, including demographic and pre-treatment characteristics, and subsequent treatment completion, provides preliminary evidence of internal validity.
