Alliance in Individual Psychotherapy

Show Summary Details


This chapter presents a research synthesis on the relation between alliance and the outcomes of individual psychotherapy. Included were over 200 research reports based on 190 independent data sources, covering more than 14,000 patients. The inclusion criteria included research involving five or more adult participants receiving genuine (as opposed to analog) treatments and the chapter referring to one of the independent variables as “alliance,” “therapeutic alliance,” “helping alliance,” or “working alliance.” Analyses were conducted using the assumptions of a random model. The overall aggregate relation between the alliance and treatment outcome (adjusted for sample size and nonindependence of outcome measures) was r = .275. The statistical probability associated with this relation is p. 〉 0.0000. The data collected for this meta-analysis were quite variable (heterogeneous). The chapter concludes with research-supported therapy practices.
