Using transtheoretical model profiles to differentiate levels of alcohol abstinence success

Using data from 673 outpatient and 510 aftercare clients in Project MATCH, this study identified drinking-outcome-related differences in profiles acro ss transtheoretical model (TTM) variables. Abstinent moderate, and heavier drinking outcome groups were formed as a function of their I-year posttreat ment drinking behavior. Using profile analysis, group differences in the sh apes of the mean profiles on TTM-related measures of stage and self-efficac y were found (a) for both the outpatient and aftercare populations and (b) at both the baseline and end-of-treatment time points. The use of cognitive and behavioral change processes during treatment was measured and the scor es for each were included in the creation of the end of treatment profiles. The relation between number of TTM goals attained and probabilities of suc cessful drinking outcome supports the usefulness of profile differences in predicting long-term drinking outcomes and can enable therapists to help cl ients set interim goals.
