OBJECTIVE Recently, innovative statistical tools have been used to model patterns of change in psychological treatments. These tools can detect patterns of change in patient progress early in treatment and allow for the prediction of treatment outcomes and treatment length. METHOD We used growth mixture modeling to identify different latent classes of(More)
OBJECTIVE The present study had 2 aims: (a) to implement West and Kenny's (2011) Truth-and-Bias model to simultaneously assess the temporal congruence and directional discrepancy between clients' and therapists' ratings of the bond facet of the therapeutic alliance, as they cofluctuate from session to session; and (b) to examine whether symptom severity and(More)
Psychotherapy does not always follow a linear path. The present study explores the frequency of sudden gains and losses during the course of outpatient psychotherapy. The sample includes 1500 patients treated at three different outpatient centers. The patients were 57.4% female, and suffered primarily from anxiety and depressive disorders. Progress was(More)
UNLABELLED Knowledge about typical change patterns of psychotherapy patients can help to improve treatment guidelines for psychological disorders. Recent studies showed that it is possible to identify several patient subgroups with regard to their early change pattern. However, although focusing on the early phase of treatment, change patterns in later(More)
OBJECTIVE There is a need for rigorous methods to study the mechanisms that lead to individual-level change (i.e., process-outcome research). We argue that panel data (i.e., longitudinal study of a number of individuals) methods have 3 major advantages for psychotherapy researchers: (1) enabling microanalytic study of psychotherapeutic processes in a(More)
OBJECTIVE This study estimates feedback and therapist effects and tests the predictive value of therapists' and patient attitudes toward psychometric feedback for treatment outcome and length. METHODS Data of 349 outpatients and 44 therapists in private practices were used. Separate multilevel analyses were conducted to estimate predictors and feedback(More)
In the last 15 years feedback interventions have had a significant impact on the field of psychotherapy research and have demonstrated their potential to enhance treatment outcomes, especially for patients with an increased risk of treatment failure. This article serves as an introduction to the special issue on "Patient-focused and feedback research in(More)
Several different approaches have been applied to identify early positive change in response to psychotherapy so as to predict later treatment outcome and length as well as use this information for outcome monitoring and treatment planning. In this study, simple methods based on clinically significant change criteria and computationally demanding growth(More)
OBJECTIVE Two patient-focused long-term research projects performed in the German outpatient psychotherapy system are focused on in this article. The TK (Techniker Krankenkasse) project is the first study to evaluate a quality assurance and feedback system with regard to its practical feasibility in German routine care. The other study ("Quality Assurance(More)
This is the first study to evaluate a quality assurance and feedback tool with regard to its practical feasibility in routine care and within the German health insurance system. This paper summarizes the evaluators' perspective on issues regarding the representativeness of the sample, consequences for therapy length and central assumptions and concepts of(More)
