Prediction of treatment-related variables using the MMPI-2 This study examined the predictive utility of the MMPI-2 in psychological treatment. A literature review was conducted of MMPI/MMPI-2 scales in relation to various treatment-related variables. In particular, the Negative Treatment Indicators content scale (TRT) and its subscales [Low Motivation (TRT1) and Inability to Disclose (TRT2)] were reviewed. Because TRT scores were found to be related to MMPI-2 scales which have already been found to be related to treatment, the question was raised as to whether TRT scores provide any additional information about treatment prediction beyond what is already provided by other MMPI-2 scales. The study sample consisted of 1020 individuals (410 men and 610 women) who sought treatment in an outpatient mental health setting and completed valid MMPI-2's. A subsample of this group was also examined, consisting of 474 clients (207 men and 267 women) for whom there are valid MMPI-2's and completed termination reports (therapists' ratings). The relationships between various MMPI-2 scales and five therapy-related variables (attendance, compliance, activity, readiness for termination, and treatment success) were examined. Initial correlational analyses were conducted and after applying the appropriate Bonferroni correction, subsequent regression analyses were conducted. The results of this study offered only limited support for the incremental validity of the TRT scales in predicting treatment-related variables. Several MMPI-2 validity and clinical scale scores were significantly correlated with therapy-related variables. Further, two scales developed specifically to predict therapy-related behavior (TRT and Es) did not always provide incremental validity above and beyond what could be predicted by an optimally weighted set of validity and clinical scales. However, in some instances, TRT and TRT1 did provide incremental validity in the prediction of therapy-related variables.
