The purpose of this study was to reanalyze the national counseling center data set with the goal of exploring the role of process variables in the prediction of clients' probabilities of various categories of counseling outcome. Specifically, the study focused on the contribution (if any) of the counselor-client working alliance to enhancing earlier prediction regarding therapy outcome category membership. Results demonstrate that adding information regarding perceptions of the quality of the unfolding process of counseling--specifically, the counselor's view of the working alliance--can significantly enhance predictions of therapy outcome category membership.
