The therapeutic alliance is considered the most robust process variable associated with positive therapeutic outcome in a variety of psychotherapeutic models [Alexander,L. B.,& Luborsky,L. (1986). The Penn Helping Alliance Scales. In L. S. Greenberg & W. M. Pinsoff (Eds.),The psychotherapeutic process: A research handbook (pp. 325–356). New York: Guilford Press; Horvath,A. O.,Gaston,L.,& Luborsky,L. (1993). The alliance as predictor of benefits of counseling and therapy. In N. Miller,L. Luborsky,J. Barber,& J. P. Docherty (Eds.),Psychodynamic treatment research: A handbook for clinical practice (pp. 247–274). New York,NY: Basic Books; Horvath,A. O.,Del Re,A. C.,Flückiger,C.,& Symonds,D. (2011). Alliance in individual psychotherapy. Psychotherapy,48,9–16; Orlinky,D.,Grawe,K.,& Parks,B. (1994). Process and outcome in psychotherapy: Noch einmal. In A. Bergin & J. S. Garfield (Eds.),Handbook of psychotherapy and behaviour change (4th ed.,pp. 270–378). New York,NY: Wiley and Sons]. The relationship between alliance and outcome has traditionally been studied based on measures that assess these therapy factors at a global level. However,the specific variations of the alliance process and their association with therapy segments that are relevant for change have not yet been fully examined. The present study examines the variations in the therapeutic alliance in 73 significant in-session events: 35 change and 38 stuck episodes identified through the observation of 14 short-term therapies of different theoretical orientations. Variations in the alliance were assessed using the VTAS-SF [Shelef,K.,& Diamond,G. (2008). Short form of the revised Vanderbilt Therapeutic Alliance Scale: Development,reliability,and validity. Psychotherapy Research,18,433–443]. Nested analyses (HLM) indicate a statistically significant better quality of the alliance during change episodes.
