Abstract

The Experiencing Scale (EXP), a measure of client's emotional processing, is often used in psychotherapy process research. While researchers agree that it predicts treatment outcomes, this relationship has not been systematically studied. This meta-analysis quantified the relationship between EXP and therapy outcomes using a total of 11 studies and 458 clients. Analysis indicated that peak EXP measured during the working phase was the strongest predictor of treatment outcomes, r = .236. Subgroup analyses indicated that working phase effects were moderated by the outcome measure modality. Early phase effects were moderated by the type of treatment and the treatment target. In accordance with the literature in the field, working phase EXP was found to be a significant predictor of clinical outcomes, although this relationship was influenced by a number of variables. Further research should look at the moderators between EXP and outcomes, and at processes that increase client experiencing.
